Exploring the potential of omics technologies in medicinal plant research: a review in Colombia / Explorando el potencial de las tecnologías ómicas en la investigación de plantas medicinales: una revisión en Colombia

This review presents advances in the implementation of high - throughput se quencing and its application to the knowledge of medicinal plants. We conducted a bibliographic search of papers published in PubMed, Science Direct, Google Scholar, Scopus, and Web of Science databases and analyzed the obtained data using VOSviewer (versi on 1.6.19). Given that medicinal plants are a source of specialized metabolites with immense therapeutic values and important pharmacological properties, plant researchers around the world have turned their attention toward them and have begun to examine t hem widely. Recent advances in sequencing technologies have reduced cost and time demands and accelerated medicinal plant research. Such research leverages full genome sequencing, as well as RNA (ribonucleic acid) sequencing and the analysis of the transcr iptome, to identify molecular markers of species and functional genes that control key biological traits, as well as to understand the biosynthetic pathways of bioactive metabolites and regulatory mechanisms of environmental responses. As such, the omics ( e.g., transcriptomics, metabolomics, proteomics, and genomics, among others) have been widely applied within the study of medicinal plants, although their usage in Colombia is still few and, in some areas, scarce.

Relationship between self-reported occupational noise exposure and expression levels of plasma inflammatory cytokines in adult asthmatic patients / 公共卫生与预防医学

Objectives To investigate the relationship between self-reported occupational noise exposure and levels of plasma inflammatory cytokines in asthmatic patients. Methods A total of 910 adult asthmatic patients were selected as the study subjects, and their occupational noise exposure history and other related information were collected. The peripheral blood samples were collected from the patients, and the expression levels of plasma soluble CD14 (sCD14), complement factor D (CFD), Eotaxin-11 (CCL11), and IL-9 were determined. The relationship between self-reported occupational noise exposure and the expression levels of the four inflammatory cytokines in patients’ plasma were analyzed using multiple linear regression models. The interactions between confounding factors and self-reported occupational noise exposure were further analyzed by interaction analysis. Results The plasma CCL11, sCD14 and CFD expressions in asthmatic patients with self-reported occupational noise exposure were significantly higher than those in patients without the exposure (P<0.05). After adjusting for confounding factors, compared with patients reporting no occupational noise exposure, the plasma CFD expression was increased by 0.17 (95% CI: 0.02, 0.31) natural logarithm units in patients with self-reported occupational noise exposure. During remission, the levels of plasma CCL11 and sCD14 in asthmatic patients with self-reported occupational noise exposure were increased by 0.27 (95% CI: 0.05, 0.49) and 0.22 (95% CI: 0.02, 0.41) natural logarithm units, respectively, when compared with patients without the exposure. Interaction analysis showed that self-reported occupational noise exposure had significant multiplicative interaction with smoking or pet ownership on plasma CCL11 or CFD expressions in asthmatic patients (all P<0.05). Conclusion Self-reported occupational noise exposure is significantly associated with increased expression levels of plasma CFD, CCL11, and sCD14 in adult asthmatic patients.

Effects of 2-dodecyl-6-methoxycyclohexa-2,5-diene-l ,4-dione on resisting hepatic fibrosis induced by CC14 in rats and its mechanisms via TGF-pi/Smads signaling pathway / 中国药理学通报

Aim To investigate the effects of 2-dode-cyl-6-methoxycyclohexa-2 , 5-diene-l, 4-dione ( DM-DD) on resisting hepatic fibrosis induced by carbon tetrachloride ( CC14 ) in rats and the underlying mechanisms , with a specific focus on the TGF-pi/Smads signaling pathway. Methods The hepatic fibrosis model was replicated using 50% CC14. Various parameters, including levels of aspartate transferase ( AST) , ala-nine transferase ( ALT ) , albumin/globulin ( A/G ) , total protein (TP) , total bilirubin (T-BIL) , hyaluron-ic acid ( HA ) , laminin ( LN ) , collagen type Ж ( Col Ж) , and collagen type IV(ColIV) in the blood, were measured. Liver tissue lesions and fiber formation were observed using HE and Masson staining. The expression levels of a smooth muscle actin (a-SMA) , collagen type I ( Col I ) , transformed growth factor (TGF-pi), Smad2, and Smad7 proteins were assessed using immunohistochemistry. a-SMA, Coll, TGF-pi, and Smad7 mRNA levels in liver tissue were measured by RT-PCR. Additionally, the expression levels of TGF-pi, Smad4, and Smad7 proteins in liver tissue were determined by Western blot. Results In comparison to the normal control group, the model group exhibited significantly elevated levels of AST, ALT, TP, T-BIL, HA, LN, Col Ш and Col IV in serum. But A/G level notably decreased. Successful modeling was confirmed by the presence of extensive fiber formations observed through HE and Massonstaining in liver tissue. The DMDD administration group demonstrated a notable decrease levels of AST, ALT, TP, T-BIL, HA, LN, Col III, and CollV, but A/G was significantly elevated when compared to the model group. Furthermore, a-SMA, Coll, TGF-f31, Smad2 and Smad4 mRNA and protein levels in the DMDD administration group were significantly reduced, while Smad7 significantly declined. HE and Masson staining results reflected a marked reduction in fibrous hyper-plasia. Conclusion DMDD exhibits a protective effect against CCl4-induced hepatic fibrosis, and its mechanism appears to be associated with the TGF-fJl/ Smads signaling pathway.

Synthesis and evaluation of 2-phenylamino-1, 4-naphthoquinones derivatives as potential hypoglycaemic agents / Síntese e avaliação de derivados de 2-fenilamino-1, 4-naftoquinonas como potenciais agentes hipoglicemiantes

Due to the severe side effects revealed by most of the currently used antidiabetic medicines, search for finding new and safe drugs to manage diabetes is continued. Naphthoquinones possessing strong antioxidant properties have been employed as candidates for diabetes therapy. Present study is aimed at finding the antioxidant and hypoglycaemic potential of some novel derivatives of 2-phenylamino-1,4-naphthoquinones (PAN) including chloro, nitro, methyl and bromo (5a-d) derivatives synthesized by single pot experiment. Product crystals were purified by TLC and characterized by FT-IR. The antioxidant potential of the compounds was assayed through DPPH radical scavenging and reducing power activities noted as UV-vis. absorbance. The DPPH assay has showed the powerful antioxidant activity of nitro and bromo derivatives, while the nitro derivative showed the significant reduction potential towards FRAP assay. Hypoglycaemic potential of the compounds was studied in rat animal model. All synthesized compounds revealed better hypoglycaemic activity; however, the chloro-derivative exhibited the more potent hypoglycaemic activity showing about 43% reduction in the mean blood glucose levels of the treated animals. As the bioreduction of naphthoquinones may be influenced by changing its redox properties, it has been noticed that the e-donating resonance effect (+R) of 'chloro' group has shown the significant effects on biological activity through stabalization of its imine form which limits the potential of generation of free radicals during bioreduction of quinones and thus has been proposed as the reason of its hypoglycaemic activity. Future studies employing the properties of e-donating groups of PAN may optimize the drug-receptor interaction for better drug designing and drug development strategies against diabetes and also for the clinical trials.

Os cristais do produto foram purificados por TLC e caracterizados por FT-IR. O potencial antioxidante dos compostos foi testado por meio de atividades de sequestro de radicais DPPH e redução de energia observada como absorção no UV-vis. O ensaio DPPH mostrou a poderosa atividade antioxidante dos derivados nitro e bromo, enquanto o derivado nitro mostrou o potencial de redução significativo para o ensaio FRAP. O potencial hipoglicêmico dos compostos foi estudado em modelo animal de rato. Todos os compostos sintetizados revelaram melhor atividade hipoglicemiante; no entanto, o derivado cloro apresentou atividade hipoglicêmica mais potente, com redução de 43% nos níveis médios de glicose no sangue dos animais tratados. Como a biorredução de naftoquinonas pode ser influenciada pela alteração de suas propriedades redox, notou-se que o efeito da doação eletrônica por ressonância (+R) do grupo "cloro" tem sido significativo na atividade biológica por meio da estabilização de sua forma imina, que limita o potencial de geração de radicais livres durante a biorredução de quinonas, e, portanto, tem sido proposto como a razão de sua atividade hipoglicemiante. Estudos futuros empregando as propriedades de grupos de doação eletrônica de PAN podem otimizar a interação droga-receptor para melhor planejamento de medicamentos e estratégias de desenvolvimento de medicamentos contra o diabetes e também para os ensaios clínicos.

Fangji Fuling Decoction Alleviates Sepsis by Blocking MAPK14/FOXO3A Signaling Pathway / 中国结合医学杂志

OBJECTIVE@#To examine the therapeutic effect of Fangji Fuling Decoction (FFD) on sepsis through network pharmacological analysis combined with in vitro and in vivo experiments.@*METHODS@#A sepsis mouse model was constructed through intraperitoneal injection of 20 mg/kg lipopolysaccharide (LPS). RAW264.7 cells were stimulated by 250 ng/mL LPS to establish an in vitro cell model. Network pharmacology analysis identified the key molecular pathway associated with FFD in sepsis. Through ectopic expression and depletion experiments, the effect of FFD on multiple organ damage in septic mice, as well as on cell proliferation and apoptosis in relation to the mitogen-activated protein kinase 14/Forkhead Box O 3A (MAPK14/FOXO3A) signaling pathway, was analyzed.@*RESULTS@#FFD reduced organ damage and inflammation in LPS-induced septic mice and suppressed LPS-induced macrophage apoptosis and inflammation in vitro (P<0.05). Network pharmacology analysis showed that FFD could regulate the MAPK14/FOXO signaling pathway during sepsis. As confirmed by in vitro cell experiments, FFD inhibited the MAPK14 signaling pathway or FOXO3A expression to relieve LPS-induced macrophage apoptosis and inflammation (P<0.05). Furthermore, FFD inhibited the MAPK14/FOXO3A signaling pathway to inhibit LPS-induced macrophage apoptosis in the lung tissue of septic mice (P<0.05).@*CONCLUSION@#FFD could ameliorate the LPS-induced inflammatory response in septic mice by inhibiting the MAPK14/FOXO3A signaling pathway.

DELEÇÃO 14q24.1: características fenotípicas e resposta ao uso hormônio do crescimento recombinante humano / 14q24.1 DELETION: phenotypic characteristics and response to the use of recombinant human growth hormone

As alterações cromossômicas estruturais no cromossomo 14 são incomuns e podem levar a um espectro variado de manifestações clínicas, incluindo hipotonia, atraso no desenvolvimento psicomotor, déficits cognitivos e dismorfismos faciais. O fenótipo específico é influenciado pela localização, extensão e pontos de interrupção da deleção. Este relato de caso tem como objetivo detalhar o fenótipo e genótipo de uma pré-escolar com deleção 14q24.1, além de documentar a resposta ao tratamento com hormônio do crescimento recombinante humano (rhGH). A paciente, uma prematura nascida com medidas adequadas para a idade gestacional e filha de pais não consanguíneos, apresentou desconforto respiratório e dificuldades de deglutição no período neonatal, necessitando de gastrostomia até o primeiro ano de vida. Entre o nascimento e os dois anos e seis meses, ela apresentou uma redução da velocidade de crescimento e baixa estatura desproporcional. Foram observados também inclinação palpebral superior bilateral, baixa inserção das orelhas, fissura palatina posterior, dentição irregular, micrognatia, retrognatia, escoliose, encurtamento do fêmur direito com marcha antálgica, agenesia do rim esquerdo e posicionamento pélvico do rim direito. Além disso, a paciente exibiu atraso no desenvolvimento neuropsicomotor. A análise genética revelou uma deleção no braço longo do cromossomo 14 de aproximadamente 231 Kb. Com o tratamento com rhGH, observou-se melhora na taxa de crescimento e na estatura final. A evolução clínica do caso indica que a administração de rhGH, associada ao acompanhamento clínico rigoroso e ao tratamento das comorbidades, pode contribuir para a melhoria dos parâmetros antropométricos.

Structural chromosomal changes on chromosome 14 are uncommon and can lead to a diverse spectrum of clinical manifestations, including hypotonia, delayed psychomotor development, cognitive deficits, and facial dysmorphisms. The specific phenotype is influenced by the location, extent, and breakpoints of the deletion. This case report aims to detail the phenotype and genotype of a preschooler with 14q24.1 deletion, in addition to documenting the response to treatment with recombinant human growth hormone (rhGH). The patient, a premature female, born with appropriate measurements for gestational age and daughter of non-consanguineous parents, presented respiratory discomfort and swallowing difficulties in the neonatal period, requiring gastrostomy until the first year of life. Between birth and two years and six months, she presented a reduction in growth speed and disproportionate short stature. Bilateral upper eyelid tilt, low ear insertion, posterior cleft palate, irregular dentition, micrognathia, retrognathia, scoliosis, shortening of the right femur with antalgic gait, agenesis of the left kidney and pelvic positioning of the right kidney were also observed. Furthermore, the patient exhibited delayed neuropsychomotor development. Genetic analysis revealed a deletion on the long arm of chromosome 14 of approximately 231 Kb. With rhGH treatment, an improvement in growth rate and final height was observed. The clinical evolution of the case indicates that the administration of rhGH, associated with strict clinical monitoring and treatment of comorbidities, can contribute to the improvement of anthropometric parameters.

Correlation of IL36RN and CARD14 mutations with clinical manifestations and laboratory findings in patients with generalised pustular psoriasis

Background: Generalized pustular psoriasis (GPP) is a chronic disease associated with genetic factors related to mutations of the interleukin 36 receptor antagonist gene (IL36RN) and the caspase recruitment domain 14 gene (CARD14). However, the relevance of these mutations to the clinical features and severity of GPP remains unclear. Aims: Our objective was to correlate the presence of IL36RN and CARD14 mutations with the clinical and laboratory findings in patients with GPP. Methods: This cross-sectional descriptive study was conducted in 64 subjects with GPP. Clinical manifestations were recorded and the severity was graded as mild, moderate, or severe. Routine laboratory tests were performed and blood samples were collected for Sanger sequencing. The clinical data of patients were compared among the different mutation groups. Results: The two main variants of IL36RN were c.115+6T > C (p.Arg10ArgfsX1) and c.227C > T (p.Pro76Leu). The major CARD14 mutations were c.2458C > T (p.Arg820Trp), c.1641C > T (p.Arg547Ser), and c.1753G > A transitions. Provocative factors were uncommon in the group with both IL36RN and CARD14 mutations. Drugs (unspecified), especially herbals, were the most common triggers. A history of psoriasis was frequent in patients with only CARD14 mutations, but fever was uncommon. The c.1641C > T mutation was associated with leukocytosis > 15000/mm3 and the c.1753G > A mutation was associated with hypoalbuminemia <3.8g/dL. Both the c.115+6T > C and c.227C > T variants of IL36RN were associated with fever ?38.5°C while the c.115+6T > C variant was also associated with geographic tongue. No gene mutations were associated with the total severity and severity grades. Limitations: Four patients without the two major IL36RN mutations were excluded from the study. Conclusion: The presence of IL36RN and CARD14 mutations were associated with a history of psoriasis, various provocative factors, fever, leukocytosis, hypoalbuminemia, and geographic tongue. Further studies to explore the role of these mutations in therapeutic efficacy and disease outcomes are necessary.

Added Effect of Pratimarsha Nasya with Ksheerabala Taila (14 Aavartita) over Selected Yoga Techniques in Insomnia

Insomnia is a prevalent psycho physiological sleeping disorder, included in the International Classification of Sleep Disorders-2 (ICSD-2). By definition insomnia is a difficulty in initiating or maintaining sleep, or both or the perception of a poor quality sleep. Insomnia leads to various social, interpersonal and occupational impairments. Clinical studies have proven that Yoga is effective in insomnia. Present study was to find out the added effect of Pratimarsha nasya with Ksheerabala taila (14 Aavartita) over selected Yoga techniques in relieving insomnia. As per Acharya Susrutha in Chikitsa Sthana, doing Pratimarsha nasya daily during evening hours (Sayamkala) renders Sukhanidraprabhodanam. A pre-post interventional study was performed in 40 participants both male and female, satisfying the inclusion and exclusion criteria. Out of 40 participants, 20 each were randomly allocated to Group I and Group II. In Group I, Pratimarsha nasya using Ksheerabala taila (14 Aavartita) was administered 1ml in each nostril at evening time along with the practice of selected yoga techniques during morning hours. In Group II, only selected Yoga techniques were advised. The study period was for 30 days. The pre & post changes in mean score value was assessed using Pittsburgh Sleep Quality Index (PSQI) score. The data was analyzed using unpaired t test, and was statistically significant with a p value ?0.01. Thus the added effect of Pratimarsha nasya with Ksheerabala taila (14 Aavrtita) over selected Yoga techniques in insomnia is more effective than selected Yoga techniques alone.

The variant was not present in healthy controls and databases.Conclusion:The homozygous mutation c.812T>C in the LSS gene may be the causative mutation for congenital hypotrichosis 14 in this family, which was a novel mutation that had not been reported before.

The role of neutrophil CD 11b, soluble CD 14 subtype and mitochondrial coupling factor-6 in the risk stratification of disease outcome in neonatal sepsis and its clinical significance / 中国医师进修杂志

Objective:To investigate the role of neutrophil CD 11b (nCD 11b), soluble CD 14 subtype (sCD 14-St) and mitochondrial coupling factor-6 (CF-6) in the risk stratification of disease outcome in neonatal sepsis and its clinical significance. Methods:The clinical data of 121 septic neonates from July 2019 to March 2020 in Shanxi Children′s Hospital were retrospectively analyzed. According to the neonatal critical illness score (NCIS), the neonates were divided into non-critical group (NCIS>90 scores) with 35 cases, critical group (NCIS 70 to 90 scores) with 49 cases, very critical group (NCIS<70 scores) with 37 cases. There were 25 cases with poor prognosis (death), and 96 cases with good prognosis (survival). The C-reactive protein (CRP), procalcitonin (PCT), nCD 11b, sCD 14-St and CF-6 before treatment were detected. The correlation between nCD 11b, sCD 14-St, CF-6 and disease severity was analyzed by Spearman method; the value of nCD 11b, sCD 14-St and CF-6 in predicting poor disease outcome in sepsis neonates was analyzed by the receiver operating characteristic (ROC) curve. Results:The nCD 11b, sCD 14-St, CF-6, PCT and CRP in critical group and very critical group were significantly higher than those in non-critical group: (414.68 ± 93.29) and (532.74 ± 101.85) MFI vs. (325.45 ± 71.90) MFI, (892.40 ± 113.72) and (1 249.53 ± 95.41) ng/L vs. (784.66 ± 103.72) ng/L, (84.79 ± 28.35) and (121.66 ± 34.27) ng/L vs. (42.59 ± 13.51) ng/L, (19.24 ± 6.30) and (34.96 ± 11.95) μg/L vs. (8.89 ± 2.24) μg/L, (109.49 ± 36.77) and (247.13 ± 82.06) mg/L vs. (56.84 ± 17.25) mg/L; the indexes in very critical group were significantly higher than those in critical group, and there were statistical differences ( P<0.05). Spearman correlation analysis result showed that nCD 11b, sCD 14-St and CF-6 were positively correlated with disease severity in sepsis neonates ( r = 0.719, 0.813 and 0.823; P<0.01). The nCD 11b, sCD 14-St, CF-6, PCT and CRP in poor prognosis neonates were significantly higher than those in good prognosis neonates: (618.58 ± 146.92) MFI vs. (374.55 ± 120.03) MFI, (1 516.91 ± 194.38) ng/L vs. (828.13 ± 175.67) ng/L, (165.84 ± 25.63) ng/L vs. (62.51 ± 16.75) ng/L, (43.46 ± 10.14) μg/L vs. (20.19 ± 6.30) μg/L and (321.09 ± 94.56) mg/L vs. (88.24 ± 29.19) mg/L, and there were statistical differences ( P<0.01). ROC curve analysis result showed that the area under the curve (AUC) of nCD 11b, sCD 14-St and CF-6 for predicting poor disease outcome in sepsis neonates were 0.763, 0.796 and 0.838 (95% CI 0.678 to 0.836, 0.713 to 0.864 and 0.760 to 0.899), and the AUC of combination the 2 indexes was 0.921 (95% CI 0.858 to 0.962). Conclusions:The nCD 11b, sCD 14-St and CF-6 are associated with the disease severity and prognosis in sepsis neonates, and can be used as markers for risk stratification of disease outcome and assessment prognosis.

Predictive value of calprotectin for acute kidney injury in patients with sepsis / 中华急诊医学杂志

Objective:To explore the predictive value and prognosis effect of calprotectin on acute kidney injury (AKI) in patients with sepsis.Methods:A prospective observational study was conducted. From December 2018 to November 2020, patients with sepsis admitted to the Emergency Department of China Rehabilitation Research Center were enrolled. General clinical data of patients were collected continuously, and the acute physiology and chronic health evaluationⅡ (APACHEⅡ) score, sequential organ failure assessment (SOFA) score and calprotectin were evaluated in 24 h after admission. The patients were divided into the AKI group and non-AKI group according to the occurrence of AKI within 7 days after admission. Calprotectin level and other clinical data were compared between the two groups. Logistic regression was used to analyze the risk factors for AKI in patients with sepsis, and receiver operating characteristic (ROC) curve was plotted to evaluate the predictive value of calprotectin for AKI in patients with sepsis. The patients with AKI were further divided into the survival group and death group according to the 28-day outcome, and the calprotectin levels between the two groups were compared.Results:A total of 207 patients with sepsis were enrolled, and the incidence of AKI was 68.12% (141/207). The level of calprotectin in patients with AKI was higher than that in patients without AKI [4.65 (3.25, 5.61) μg/mL vs. 3.42 (2.29, 4.09) μg/mL, P < 0.001]. Multivariable Logistic regression analysis showed that APACHEⅡ score ( OR=1.090, 95% CI: 1.043-1.139), C-reactive protein ( OR=1.004, 95% CI: 1.001-1.008) and calprotectin ( OR=1.590, 95% CI: 1.269-1.991) were independent risk factors for AKI in patients with sepsis. The area under ROC curve (AUC) of calprotectin for predicting AKI was 0.716 (95% CI: 0.643-0.788). The cutoff value of prediction was 4.63 μg/mL with the Yoden index of 0.405, which yielded a sensitivity of 0.511 and a specificity of 0.894. When calprotectin was combined with APACHE II score and SOFA score respectively, the predictive ability was significantly improved with the AUC of 0.768 (95% CI: 0.701-0.834) and 0.769 (95% CI: 0.701-0.837), respectively. We further divided patients with AKI into the survival group and non-survival group according to the 28-day outcome and there was no significant difference in calprotectin between the two groups [4.80 (3.40, 5.76) μg/mL vs. 4.19 (2.89, 5.29) μg/mL, P < 0.05]. Conclusions:The level of calprotectin in the AKI group is higher than that in the non-AKI group. Calprotectin can be regarded as an effective predictor of AKI in patients with sepsis, and the combination with APACHEⅡ score or SOFA score will improve its predictive efficacy. However, there is no significant difference in the concentration of calprotectin for patients with sepsis associated AKI with different prognosis.

Treatment status of non-small cell lung cancer with METexon14 skipping mutation / 国际肿瘤学杂志

MET exon14 (METex14) skipping mutation is an independent driver gene in non-small cell lung cancer (NSCLC) . About 3%-4% of NSCLC patients carry METex14 skipping mutation. These patients have poor prognoses and poor responses to traditional chemotherapy and immunotherapy. Highly selective MET inhibitors such as capmatinib, tepotinib, savolitinib have shown good efficacy and safety data in clinical trials, which bring new treatment options for patients with METex14 skipping mutations.

The Deubiquitinating Enzyme USP14 Promotes the Proliferation and Migration Ability of Pancreatic Cancer Cells / 中国生物化学与分子生物学报

Pancreatic cancer remains one of the deadliest cancer types with few effective treatment options. While the overexpression of ubiquitin-specific protease 14 (USP14) has been observed in many tumor cells, including pancreatic cancer cells, its precise role in pancreatic cancer is not well defined. Here, we investigated the biological function of USP14 in pancreatic cancer and its molecular mechanisms. Our analysis of the Cancer Genome Atlas database revealed that USP14 was highly expressed in pancreatic cancer tissues,and further investigation revealed that its expression level was negatively correlated with the prognosis of patients. In SW1990 and MIAPaCa2 pancreatic cancer cells,we established stable USP14-knockdown cell lines using the shRNA-USP14 lentivirus and found that USP14 knockdown inhibited the proliferation and migration ability of pancreatic cancer cells by CCK8, colony formation assay, wound-healing and Transwell assays. Western blotting analysis showed that downregulation of USP14 expression resulted in a decrease in CyclinD3 protein levels, while overexpression of USP14 increased the protein levels in SW1990 and MIAPaCa2 pancreatic cancer cells. Furthermore, co-immunoprecipitation demonstrated that USP14 interacts with CyclinD3 and ubiquitination assays show that overexpression of USP14 reduces the ubiquitination level of CyclinD3. Moreover, CRISPR / Cas9-mediated USP14 knockout in SW1990 pancreatic cancer cells resulted in decreased CyclinD3 protein levels. These findings suggest that USP14 promotes the proliferation and migration ability of pancreatic cancer cells by interacting with CyclinD3, highlighting USP14 as a potential therapeutic target for pancreatic cancer.
