Integrated pan-cancer genomic analysis reveals the role of SLC30A5 in the proliferation, metastasis, and prognosis of hepatocellular carcinoma.

Background: SLC30A5, a member of the solute transporter protein family, is implicated in tumorigenesis and cancer progression. This study aimed to explore the expression and prognostic significance of SLC30A family genes in pan-cancer, with a specific emphasis on SLC30A5 in hepatocellular carcinoma (HCC). Methods: Expression patterns and prognostic implications of SLC30A family genes were assessed across 33 cancer types, especially HCC. Co-expression analysis explored the relationship between SLC30A5 and immune cell infiltration, immune checkpoints, pathway molecules related to tumor angiogenesis and epithelial-mesenchymal transition (EMT). The role of SLC30A5 in HCC was evaluated through in vitro and in vivo assays, including CCK8 viability assay, EdU cell proliferation assay, colony formation assay, apoptosis assay, wound healing assay, transwell migration assay, and xenograft mouse model assay using Huh7 cells with targeted knockdown of SLC30A5. Results: SLC30A family genes exhibited overexpression in various tumors. In HCC, upregulation of SLC30A5 expression correlated with adverse prognosis. Significant associations were observed between SLC30A5 expression and immune cell infiltration, immune checkpoints, molecules involved in angiogenesis, and EMT. SLC30A5 overexpression was associated with advanced disease stages, higher histological grades, and vascular invasion. Single-cell RNA sequencing data (GSE112271) revealed notable SLC30A5 expression in malignant cells. In vitro and in vivo assays demonstrated that SLC30A5 knockdown in Huh7 cells reduced proliferation, migration, and invasion while promoting apoptosis. Conclusions: This study highlights the clinical relevance of SLC30A5 in HCC, emphasizing its role in cell proliferation and migration. SLC30A5 emerges as a promising candidate for a prognostic marker and a potential target in HCC.

[Network Meta-analysis of traditional Chinese medicine injections in treatment of chronic pulmonary heart disease].

Based on the network Meta-analysis, the efficacy and safety of different traditional Chinese medicine(TCM) injections in the treatment of chronic pulmonary heart disease(CPHD) were systematically evaluated. CNKI, Wanfang, VIP, SinoMed, Web of Science, PubMed, EMbase, and Cochrane Library were searched to collect randomized controlled trial(RCT) of TCM injection in the treatment of CPHD from inception to October 1, 2023. The quality of the included studies was evaluated by the bias risk assessment tool recommended by the Cochrane systematic evaluation manual version 5.3. Stata 17.0 and RevMan 5.4 software were used for statistical analysis of the data. Finally, 103 RCTs were included, involving 9 332 patients and 13 kinds of TCM injections. Network Meta-analysis yielded the following results.(1)In terms of improving the total clinical effective rate, the top three intervention measures in SUCRA ranking are Shuxuetong Injection + conventional western medicine>Ligustrazine Injection + conventional western medicine>Xinmailong Injection + conventional western medicine.(2)In terms of reducing pulmonary artery pressure, the top three intervention measures in SUCRA ranking are Salvia Miltiorrhiza Ligustrazine Injection + conventional western medicine>Ligustrazine Injection + conventional western medicine>Shenmai Injection + conventional western medicine.(3)In terms of improving left ventricular ejection fraction(LVEF), the top three intervention measures in SUCRA ranking are Xinmailong Injection + conventional western medicine>Danhong Injection + conventional western medicine>Ginkgo Damo Injection + conventional western medicine.(4) In terms of reducing brain natriuretic peptide(BNP), the top three intervention measures in SUCRA ranking are Xinmailong Injection + conventional wes-tern medicine>Ginkgo Damo Injection + conventional western medicine>Danhong Injection + conventional western medicine.(5) In terms of increasing arterial oxygen partial pressure(PaO_2) and reducing arterial carbon dioxide partial pressure(PaCO_2), the top three intervention measures in SUCRA ranking are Shenxiong Glucose Injection + conventional western medicine>Shenmai Injection + conventional western medicine>Shenfu Injection + conventional western medicine.(6) In terms of improving arterial oxygen saturation(SaO_2), the top three intervention measures in SUCRA ranking are Salvia Miltiorrhiza Ligustrazine Injection + conventional western medicine>Xinmailong Injection + conventional western medicine>Shenmai Injection + conventional western medicine.(7) In terms of increasing the percentage of forced expiratory volume in the first second(FEV_1%), the top three intervention measures in SUCRA ranking are Shenfu Injection + conventional western medicine>Tanshinone Sodium Ⅱ_A Sulfonate Injection + conventional western medicine>Shenmai Injection + conventional western medicine.(8) In terms of increasing the proportion of forced expiratory volume to forced vital capacity in the first second(FEV_1/FVC), the top three intervention measures in SUCRA ranking are Salvia Miltiorrhiza Ligustrazine Injection + conventional western medicine>Shuxuetong Injection + conventional western medicine>Danhong Injection + conventional western medicine.(9) In terms of safety, neither the experimental group nor the control group experienced any serious adverse drug reactions during the treatment period. In summary, combining TCM injection with conventional western medicine treatment can improve the comprehensive efficacy of treating CPHD, reduce pulmonary artery pressure, and improve cardiopulmonary function and arterial blood gas levels. However, due to the limitations of the quality and quantity of research methodology included, the above conclusions need to be further validated by more well-designed and high-quality RCT.

Multiple coronary heart diseases are risk factors for mental health disorders: A mendelian randomization study.

BACKGROUND: Previous observational studies have suggested associations between Coronary Heart Disease (CHD) and Mental Health Disorders (MHD). However, the causal nature of these relationships has remained elusive. OBJECTIVE: The purpose of this study is to elucidate the causal relationships between eight distinct types of CHD and six types of MHD using Mendelian randomization (MR) analysis. METHODS: The MR analysis employed a suite of methods including inverse variance-weighted (IVW), MR-Egger, weighted mode, weighted median, and simple mode techniques. To assess heterogeneity, IVW and MR-Egger tests were utilized. MR-Egger regression also served to investigate potential pleiotropy. The stability of IVW results was verified by leave-one-out sensitivity analysis. RESULTS: We analyzed data from over 2,473,005 CHD and 803,801 MHD patients, informed by instrumental variables from large-scale genomic studies on European populations. The analysis revealed a causal increase in the risk of Major Depressive Disorder and Mania associated with Coronary Artery Disease and Myocardial Infarction. Heart Failure was found to causally increase the risk for Bipolar Disorder and Schizophrenia. Atrial Fibrillation and Ischemic Heart Diseases were positively linked to Generalized Anxiety Disorder and Mania, respectively. There was no significant evidence of an association between Hypertensive Heart Disease, Hypertrophic Cardiomyopathy, Pulmonary Heart Disease, and MHD. Reverse MR analysis indicated that MHD do not serve as risk factors for CHD. CONCLUSIONS: The findings suggest that specific types of CHD may act as risk factors for certain MHDs. Consequently, incorporating psychological assessments into the management of patients with CHD could be advantageous.

Associations between gut microbiota and gynecological cancers: A bi-directional two-sample Mendelian randomization study.

Growing evidence has suggested that gut microbiota is associated with gynecologic cancers. However, whether there is a causal relationship between these associations remains to be determined. A two-sample Mendelian randomization (MR) evaluation was carried out to investigate the mechanism associating gut microbiota and 3 prevalent gynecological cancers, ovarian cancer (OC), endometrial cancer, and cervical cancer as well as their subtypes in individuals of European ancestry. The Genome-wide association studies statistics, which are publically accessible, were used. Eligible instrumental single nucleotide polymorphisms that were significantly related to the gut microbiota were selected. Multiple MR analysis approaches were carried out, including inverse variance weighted, MR-Egger, Weighted Median methods, and a range of sensitivity analyses. Lastly, we undertook a reverse MR analysis to evaluate the potential of reverse causality. We sifted through 196 bacterial taxa and identified 33 suggestive causal relationships between genetic liability in the gut microbiota and gynecological cancers. We found that 11 of these genera could be pathogenic risk factors for gynecological cancers, while 19 could lessen the risk of cancer. In the other direction, gynecological cancers altered gut microbiota composition. Our MR analysis revealed that the gut microbiota was causally associated with OC, endometrial cancer, and cervical cancer. This may assist in providing new insights for further mechanistic and clinical studies of microbiota-mediated gynecological cancer.

Immunotherapy-associated cardiovascular toxicities: insights from preclinical and clinical studies.

Immune checkpoint inhibitors (ICIs) have become a widely accepted and effective treatment for various types of solid tumors. Recent studies suggest that cardiovascular immune-related adverse events (irAEs) specifically have an incidence rate ranging from 1.14% to more than 5%. Myocarditis is the most common observed cardiovascular irAE. Others include arrhythmias, pericardial diseases, vasculitis, and a condition resembling takotsubo cardiomyopathy. Programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) pathway, cytotoxic T-lymphocyte antigen-4 (CTLA-4) pathway, and the recently discovered lymphocyte-activation gene 3 (LAG-3) pathway, play a critical role in boosting the body's natural immune response against cancer cells. While ICIs offer significant benefits in terms of augmenting immune function, they can also give rise to unwanted inflammatory side effects known as irAEs. The occurrence of irAEs can vary in severity, ranging from mild to severe, and can impact the overall clinical efficacy of these agents. This review aims to summarize the underlying mechanisms of cardiovascular irAE from both preclinical and clinical studies for a better understanding of cardiovascular irAE in clinical application.

A Mendelian randomization study on the causal association of circulating cytokines with colorectal cancer.

BACKGROUND: Circulating cytokines have been associated with colorectal cancer (CRC). However, their causal correlation remains undetermined. This investigation uses genetic data to evaluate the mechanism that links circulating cytokines and CRC via Mendelian Randomization (MR). METHODS: A two-sample MR evaluation was carried out to investigate the mechanism associating circulating cytokines and CRC in individuals of European ancestry. The Genome-wide association studies statistics, which are publically accessible, were used. Eligible instrumental SNPs that were significantly related to the circulating cytokines were selected. Multiple MR analysis approaches were carried out, including Simple Mode, inverse variance weighted (IVW), MR-Egger, Weighted Mode, Weighted Median, and MR pleiotropy residual sum and outlier (MR-PRESSO) methods. RESULTS: The evidence supporting the association of genetically predicted circulating levels with the increased risk of CRC was revealed; these included vascular endothelial growth factor (OR = 1.352, 95% CI: 1.019-1.315, P = 0.024), interleukin-12p70 (OR = 1.273, 95% CI: 1.133-1.430, P = 4.68×10-5), interleukin-13 (OR = 1.149, 95% CI: 1.012-1.299, P = 0.028), interleukin-10 (OR = 1.230, 95% CI: 1.013-1.493, P = 0.037), and interleukin-7 (OR = 1.191, 95% CI: 1.023-1.386 P = 0.024). Additionally, MR analysis negative causal association between macrophage colony stimulating factor and CRC (OR = 0.854, 95% CI: 0.764-0.955, P = 0.005). The data from Simple Mode, Weighted Median, MR-Egger, and Weighted Mode analyses were consistent with the IVW estimates. Furthermore, the sensitivity analysis indicated that the presence of no horizontal pleiotropy to bias the causal estimates. CONCLUSION: This investigation identified a causal association between circulating cytokines levels risk of CRC and may provide a deeper understanding of the pathogenesis of CRC, as well as offer promising leads for the development of novel therapeutic targets for CRC.

Ethyl acetate extract of Caesalpinia sappan L. for the treatment of atherosclerosis in ApoE-/- mice and its mechanism.

The ethyl acetate extract of Caesalpinia sappan L. is a traditional Chinese medicine extract commonly used in the treatment of atherosclerosis. However, the mechanism of its use in the treatment of AS is not yet clear, which seriously affects the wide-scale application of this drug. In this study, a combination of metabolomics and lipidomics was used to analyze cardiac tissue to obtain differential metabolites and differential lipid molecules, bioinformatic analysis was performed on the significantly different metabolites and subclass analysis, cluster analysis, and chain length and chain saturation analyses were performed on screened lipid molecules showing significant differences. A correlation network diagram of the screened differential metabolites and differential lipid molecules was constructed. Hematoxylin and eosin staining of thoracic aorta in rats confirmed its therapeutic effect. This study found that the ethyl acetate extract of C. sappan L. upregulates D-mannose through the lysosome pathway, enhances lysosomal function, mediates autophagy, and indirectly regulates the levels of lipid subtypes such as lysophosphatidylinositol and phosphatidylserine, thereby improving AS.

Scutellarin alleviates type 2 diabetes (HFD/low dose STZ)-induced cardiac injury through modulation of oxidative stress, inflammation, apoptosis and fibrosis in mice.

BACKGROUND: Diabetes is a serious global health concern which severely affected public health as well as socio-economic growth worldwide. Scutellarin (SCU), a bioactive flavonoid, is known for its efficacious action against a range of ailments including cardiovascular problems. The present study was conducted to find out possible protective effect and its associated mechanisms of SCU on experimental type 2 diabetes-induced cardiac injury. METHODS: Type 2 diabetes was induced by treating animals with high fat diet for 4 weeks and a single intraperitoneal dose (35 mg/kg body weight) of streptozotocin and diabetic animals received SCU (10 or 20 mg/kg/day) for 6 weeks. RESULTS: Scutellarin attenuated type 2 diabetes-induced hyperglycemia, bodyweight loss, hyperlipidaemia, cardiac functional damage with histopathological alterations and fibrosis. Scutellarin treatment to type 2 diabetic mice ameliorated oxidative stress, inflammatory status and apoptosis in heart. Furthermore, the underlying mechanisms for such mitigation of oxidative stress, inflammation and apoptosis in heart involved modulation of Nrf2/Keap1 pathway, TLR4/MyD88/NF-κB mediated inflammatory pathway and intrinsic (mitochondrial) apoptosis pathway, respectively. CONCLUSIONS: The current findings suggest that SCU is effective in protecting type 2 diabetes-induced cardiac injury by attenuating oxidative stress and inflammatory responses and apoptosis, and it is also worth considering the efficacious potential of SCU to treat diabetic cardiomyopathy patients.

MiR-145-5p modulates lipid metabolism and M2 macrophage polarization by targeting PAK7 and regulating ß-catenin signaling in hyperlipidemia.

The present study aims to explore the role of microRNA 145-5p (miR-145-5p) in hyperlipidemia. Using bioinformatics tools and a wide range of function and mechanism assays, we attempted to understand the specific function and potential mechanism of miR-145-5p in hyperlipidemia. A cholesterol-enriched diet induced an increase of serum cholesterol and triacylglycerol but a decrease of serum high-density lipoprotein. MiR-145-5p level was decreased in hyperlipidemia rat models. MiR-145-5p regulated lipid metabolism by antagonizing the alteration of high-density lipoprotein, cholesterol, and triacylglycerol in serum mediated by a cholesterol-enriched diet. In mechanism, miR-145-5p directly bound with p21 protein (RAC1)-activated kinase 7 (PAK7) and negatively regulated mRNA and protein levels of PAK7 in THP-1 cells. Furthermore, miR-145-5p level was negatively associated with PAK7 level in rat cardiac tissues. Finally, overexpression of PAK7 reversed the effects of miR-145-5p on ß-catenin activation and M2 macrophages polarization in THP-1 cells. In conclusion, MiR-145-5p modulated lipid metabolism and M2 macrophage polarization by targeting PAK7 and regulating ß-catenin signaling in hyperlipidemia, which may provide a potential biomarker for the treatment of hyperlipidemia-induced cardiovascular diseases.

Ethyl acetate extract of sappanwood alleviates experimental atherosclerosis in rats through changes in FGF21 and SREBP-2 expression.

Sappanwood extract shows promising effects against atherosclerosis. The fibroblast growth factor 21 (FGF21) and sterol regulatory element-binding protein 2 (SREBP2) are involved in atherosclerosis development. This study aimed to examine whether sappanwood ethyl acetate extract (SEAE) alleviates experimental atherosclerosis in rats through FGF21/SREBP-2 signaling. Rats were randomized to six groups (n=10/group): blank control, model, simvastatin (positive control, 4.2 mg/kg/d), and SEAE high-, medium-, and low-dose (2.30, 1.15, and 0.575 g/kg/d, respectively). The high-fat- and vitamin D3-induced rodent model of atherosclerosis was created (except in the blank control group). Aorta and liver underwent histopathologic examination. SREPB-2 and FGF21 expression levels were examined by real-time RT-PCR and western blot. Compared with the blank control group, the model group showed aortic and hepatic histopathology compatible with the development of atherosclerosis due to a high-fat diet. In addition, total cholesterol, triglycerides, and low-density lipoprotein cholesterol (LDL-C) were elevated (all P<0.05). SREBP2 expression was high, and FGF21 expression was low (both P<0.05). Compared with the model group, SEAE alleviated the changes in liver and aorta by histopathology and decreased total cholesterol, triglycerides, and LDL-C (all P<0.05), especially in the medium-, and high-dose groups. In addition, medium-dose SEAE increased FGF21 levels (mRNA: +296%; protein: +69%; P<0.05) and decreased SREBP2 levels (mRNA: -44%; protein: -77%; P<0.05). Simvastatin, as the positive control, had similar effects to those of SEAE. In conclusion, SEAE improves lipid metabolism and alleviates atherosclerosis through changes in FGF21 and SREBP-2 expression levels.
