ABSTRACT

Objective:To investigate the effect of miR-375-3p on DNA damage repair and radioresistance of colorectal cancer cells.Methods:After overexpression of miR-375-3p in HCT116 and HT29, cell proliferation ability was detected by CCK-8 assay, clone formation ability was detected by clone formation assay, apoptosis was detected by Annexin V-FITC/PI double staining method and cell cycle distribution was detected by flow cytometry, and the formation of γ-H2AX foci were used to analyze homologous recombination (HR) repair efficiency. Bioinformatics was used to predict the downstream target genes of miR-375-3p in the HR repair pathway. A dual luciferase reporter gene assay was used to validate the regulation effect of miR-375-3p on Rad51 gene. The expression of miR-375-3p in HCT116 cells irradiated with 60Co γ-rays at 2 and 6 Gy was measured by RT-qPCR. The inhibition effect of miR-375-3p on the radiosensitivity of HCT116 cells was analyzed after irradiation with different doses of 0, 1, 2, 4 and 6 Gy. Results:Overexpression of miR-375-3p inhibited the proliferation and colony formation ability, induced G1 phase cycle arrest and cell apoptosis of colorectal cancer cells, enhanced DSBs formation, inhibited Rad51 expression, and significantly decreased HR repair efficiency ( t = 10.055, P < 0.05). Dual luciferase reporter gene assay demonstrated that miR-375-3p bound to Rad51 3′UTR region ( t = 5.013, P< 0.05). In addition, irradiation increased miR-375-3p expression, and inhibition of miR-375-3p expression reduced radiosensitivity of colorectal cancer cells ( t=6.460, 5.619, 10.150, P<0.05). Conclusions:miR-375-3p inhibited the homologous recombination repair efficiency of DSBs and enhanced the radiosensitivity of colorectal cancer cells.

ABSTRACT

Objective:Donor cytomegalovirus (CMV) serological negative status may have an adverse effect on the outcome of allogeneic hematopoietic stem cell transplantation (allo-HSCT), while there is inadequate data for Chinese people. This study is to explore the impact of donor CMV serological status on the outcome of CMV seropositive patients receiving allo-HSCT.Methods:Our study retrospectively analyzed 16 CMV seropositive patients with hematological malignancies receiving allogeneic grafts from CMV seronegative donors (antibody IgG negative) at Peking University People′s Hospital from March 2013 to March 2020, which was defined as D -/R + group. The other 64 CMV seropositive patients receiving grafts from CMV seropositive donors at the same period of time were selected as matched controls through a propensity score with 1∶4 depending on age, disease state and donor-recipient relationship (D +/R + group). Results:Patients in D -/R + group developed CMV DNAemia later than patients in the D +/R + group (+37 days vs. +31 days after allo-HSCT, P=0.011), but the duration of CMV DNAemia in D -/R + group was longer than that of D +/R + group (99 days vs. 34 days, P=0.012). The rate of CMV reactivation 4 times or more in D -/R + group was 4/16, significantly higher than that of D +/R + group (4.7%, 3/64, P=0.01). The incidences of refractory CMV DNAemia (14/16 vs. 56.3%, P=0.021) and CMV disease (4/16 vs. 4.7%, P=0.01) in D -/R + group were both higher than those in D +/R + group. In addition, the application of CMV-CTL as the second-line antiviral treatment in D -/R + group was more than that in D +/R + group. Univariate analysis and multivariate analysis suggested that CMV serological negativity is an independent risk factor for refractory CMV DNAemia and the duration of CMV infection. The cumulative incidence of aGVHDⅡ-Ⅳ, cGVHD, 3-year probability of NRM, overall survival, and the cumulative incidence of relapse were all comparable in two groups. Conclusions:Although there is no significant effect on OS and NRM, the incidence of refractory CMV DNAemia, the frequency of virus reactivation, and the development of CMV disease in D -/R + group are higher than those in controls. Therefore, CMV seropositive donors are preferred for CMV seropositive patients.

ABSTRACT

Objective:To investigate the incidences and risk factors of poor hematopoietic reconstitution (PHR) in patients with hematological diseases who underwent haploidentical allograft and were treated with rituximab for desensitization.Methods:Eight-three donor specific anti-HLA antibody (DSA, 2000 ≤MFI<10 000) positive patients who underwent haploidentical allograft were prospectively enrolled. Rituximab (375 mg/m 2) was used for desensitization day-3 of conditioning regimen. Incidence and factors associated with PHR, including primary poor graft function and prolonged thrombocytopenia, were investigated. Results:There were 22 males and 61 females with a median age of 39(range: 1-65) years. Kaplan-Meier analysis showed that the 100 day cumulative incidences of neutrophil and platelet engraftment were 93.0% and 90.7%, respectively. The incidences of PHR were 14.7%. The 3-year relapse rate, non-relapse mortality (NRM) rate, event-free survival (EFS), leukemia-free survival (DFS) and overall survival (OS) were 6.5%, 15.1%, 70.8%, 79.4% and 79.4%, respectively. Patients with DSA MFI<5 000 (group A, n=46) experienced lower PHR (4.4% vs. 27.5%, P=0.003), and higher 3-year EFS (79.5% vs. 59.8%, P=0.020) compared to those with DSA MFI≥5 000 (group B, n=37). Multivariate analysis showed that DSA MFI≥5 000 was correlated with PHR ( HR=6.101, P=0.021). PHR was associated with higher NRM ( HR=4.110, P=0.026), lower DFS ( HR=3.656, P=0.019) and OS ( HR=3.656, P=0.019). Conclusion:Our data suggest that high pre-transplant DSA level is a risk factor for PHR in patients with hematological diseases receiving haploidentical allograft and rituximab for desensitization.

ABSTRACT

BACKGROUND@#Psoriasis is a common, chronic, immune-mediated inflammatory skin disease with increased epidermal proliferation. The objective of this review was to systematically identify the evidence and perform a network meta-analysis (NMA) to estimate the relative efficacy of secukinumab (SEC) against adalimumab (ADA) and infliximab (INF) for the treatment of moderate-to-severe plaque psoriasis.@*METHODS@#A systematic literature review (SLR) was conducted according to a pre-specified protocol to identify relevant studies. Initially, the databases were searched from database inception till June 2013, and the SLR was updated in April 2020. The eligibility criteria included adult patients (≥18 years old) with moderate-to-severe plaque psoriasis, and the SLR included randomized controlled trials (RCTs). The comparators of interest were SEC, ADA, INF, and placebo (PLA), while outcomes of interest were Psoriasis Area and Severity Index (PASI) (50, 75, and 90) at weeks 12, 16, and 24. A Bayesian NMA for PASI was utilized with a framework that evaluated the probability of PASI responses in different categories of PASI thresholds within a single model.@*RESULTS@#A total of 23 RCTs that assessed the efficacy of SEC, ADA, and INF in patients with moderate-to-severe plaque psoriasis were identified. At 12 weeks, SEC was associated with a significantly better response compared with PLA and ADA for PASI 75 and 90, while response results were comparable against INF. At 12 weeks, risk ratio (95% confidence interval) derived from NMA for SEC vs. ADA and INF for PASI 75 was 1.35 (1.19, 1.57) and 1.01 (0.90, 1.18), respectively. At the 16-week and 24-week time interval, SEC was significantly better than PLA, ADA, and INF for PASI 75 and 90.@*CONCLUSION@#Efficacy of SEC in the treatment of patient populations with moderate-to-severe plaque psoriasis is well demonstrated through NMA.

ABSTRACT

Objective:To investigate the value of minimal residual disease (MRD) in prediction of prognosis in acute lymphoblastic leukemia (ALL) patients with or above complete remission 2 (CR2) underwent.Methods:A retrospective analysis was performed on 201 ALL patients who received allogeneic stem cell transplantation (allo-SCT) and pretransplant disease status ≥CR2 in Peking University People′s Hospital from January 2009 to December 2018. MRD was measured by multi-parameter flow cytometry at 1 month before transplantation and 1 month, 2 months, 3 months, 4 months, 6 months, 9 months or 12 months after transplantation. To investigate the influence of dynamic changes of MRD before and after transplantation on prognosis.Results:201 ALL patients, including 126 males and 75 females, with a median age of 18 years. The 3-year cumulative incidence of relapse (CIR), non-relapse mortality (NRM), leukemia-free survival (LFS) and overall survival (OS) of all cases were 34%, 16%, 50%, and 56%, respectively. Positive pre-SCT MRD patients with higher 3-year CIR (47% vs 26%, P=0.003), lower 3-year LFS (40% vs 55%, P=0.047) and OS (42% vs 60%, P=0.065) than those with negative one. Subjects with positive post-MRD had higher 3-year CIR (73% vs 22%, P<0.001) and lower 3-year LFS (28% vs 56%, P=0.005) and OS (32% vs 60%, P=0.040) compared with those with negative one. Multivariate analysis showed that both pre-MRD and post-MRD were associated with higher CIR ( HR=1.823, P=0.018; HR=3.474, P<0.001), lower LFS ( HR=1.779, P=0.007; HR=2.185, P=0.001) and OS ( HR=1.609, P=0.034; HR=1.970, P=0.001). Negative pre-and post-SCT MRD group had lower 3-year CIR (17%, 42%, 82%; P<0.001) and higher 3-year LFS (61%, 44%, 18%; P<0.001) and OS (63%, 47%, 27%; P<0.001) compared with those unrisen post-SCT MRD group, and increased post-SCT MRD group. Multivariate analysis showed that pre-and post-SCT MRD dynamics were associated with CIR, LFS and OS ( P<0.01 for all) independently. The pre-and post-SCT MRD dynamics could better distinguish CIR (C=0.669) from that of pre-SCT MRD (C=0.587) and post-SCT MRD (C=0.629). Conclusion:Our data suggest that pre-SCT MRD, post-SCT MRD and the dynamic peri-SCT MRD could be used to predict transplant outcome of ALLpatients with or above CR2 who underwent allo-SCT.

ABSTRACT

OBJECTIVE@#To investigate the regulatory role of Musashi-1 (MSI1) in the proliferation and growth of hepatocellular carcinoma (HCC) cells.@*METHODS@#We examined the expression of MSI1 in HCC and paired adjacent tissues from 24 patients using immunohistochemistry and Western blotting. A MSI1-expressing vector was constructed and stably transfected into HepG2 cells, and short hairpin RNAs (shRNAs) that targeted MSI1 mRNA were ligated into the vector and stably transfected in Huh7 cells. The effects of MSI1 overexpression and silencing on the proliferation, viability and cell cycle of HepG2 cells were investigated using flow cytometry or MTT assay. The expressions of PCNA, cyclin D1, APC and β-catenin in the HCC cells were detected with Western blotting.@*RESULTS@#MSI1 expression was significantly up-regulated in HCC tissues as compared with that in the adjacent tissues. Overexpression of MSI1 in HepG2 cells resulted in significantly enhanced cell growth ( < 0.01) and significantly reduced G0/G1 phase cells from (58.42±3.18)% to (40.67±1.22)% and increased S phase cells from (28.51± 1.93)% to (40.06±1.92)% ( < 0.01), causing also increases in the expressions of PCNA and Cyclin D1. Knockdown of MSI1 in Huh7 cells obviously inhibited the cell growth and caused cell cycle arrest at the G1/S phase ( < 0.01) with reduced protein expressions of PCNA and cyclin D1. Overexpression of MSI1 in HepG2 cells also down-regulated the expression of APC and up-regulated the expression of β-catenin protein, while MSI1 knockdown caused reverse changes in Huh7 cells.@*CONCLUSIONS@#MSI1 promotes the progression of HCC through positive modulation of cell growth and cell cycle the Wnt/β-catenin pathway.

ABSTRACT

OBJECTIVE@#To investigate the interaction between interleukin-17 (IL-17) and interferon-γ (IFN-γ) and how their interaction affects the growth of mouse hepatoma Hepa1-6 cells.@*METHODS@#Hepa1-6 cells treated with IL-17 and IFN-γ either alone or in combination were examined for changes in cell proliferation using MTT assay and in cell cycle distribution using flow cytometry. Western blotting was used to detect the protein expression levels of proliferating cell nuclear antigen (PCNA), cyclin D1, P21 and P16 and the phosphorylation of p38MAPK, ERK1/2 and Stat1 in the cells.@*RESULTS@#Compared with control group, IFN-γ treatment obviously inhibited the growth and proliferation of Hepa1-6 cells, induced cell cycle arrest at G0/G1 phase, reduced the protein expression of PCNA and cyclin D1, and increased the protein expression of P21. IL-17 alone had no effect on the growth of Hepa1-6 cells. In the combined treatment, IL-17 significantly antagonized the effects of IFN-γ. Compared with those treated with IFN-γ alone, the cells with the combined treatment showed significantly decreased G0/G1 cell population, increased the protein expressions of PCNA and cyclin D1, and decreased the protein expression of P21. IL-17 significantly inhibited IFN-γ-induced phosphorylation of p38MAPK and ERK1/2 without affecting the phosphorylation of Stat1.@*CONCLUSIONS@#IL-17 obviously reverses the antitumor effects of IFN-γ to promote the proliferation of mouse hepatoma cells and accelerate the development of hepatocellular carcinoma.

ABSTRACT

Objective@#To investigate the association of hematological complete remssion (HCR) status on the outcomes of the patients with B-cell acute lymphoblastic leukemia (B-ALL) who were undergoing haploidentical stem cell transplantation (Haplo-SCT). @*Methods@#Retrospective analysis was performed on 317 patients with B-ALL who received Haplo-SCT with HCR before transplantation in the Institute of Hematology, Peking University from September 2012 to June 2016. A Cox proportional hazards model was used to analyze the effects of HCR status before transplantation on the outcomes of Haplo-SCT. @*Results@#The 3-year cumulative incidences of non-relapse mortality (NRM) and cumulative incidence of relapse (CIR) were 15% and 15%, respectively. The 3-year probabilities of leukemia-free survival (LFS) and overall survival (OS) were 71% and 74%, respectively. There was no statistical difference for 3-year NRM, CIR and LFS among the HCR patients with recovery of absolute neutrophil count (ANC) and platelet (CR) group, without recovery of ANC and with or without recovery of platelet (CRi) group and those in HCR with recovery of ANC but without recovery of platelet (CRp) group (P value >0.05 for all). The probability of OS in cases of CR group was significantly higher than that of CRi group (76% vs 59%,P=0.049). Multivariate analysis showed that factors associated with CIR included pre-transplantation minimal residual disease (P=0.006) and chronic GVHD (P=0.020). Platelet engraftment was associated with NRM, LFS, and OS (P<0.001 for all). Grades Ⅲ-Ⅳ GVHD was associated with NRM (P<0.001) and OS (P=0.035). Chronic GVHD was correlated with LFS (P<0.001). @*Conclusion@#Our results indicate that no effect of HCR status before transplant on the outcomes was observed in patients with B-ALL who underwent Haplo-SCT.

ABSTRACT

Objective@#To screen the target genes of long non-coding RNA LOC102606465, which was previously identified to be induced by ionizing radiation, in order to examine its potential biological role.@*Methods@#The downstream differentially expressed genes (DEGs) of LOC102606465 were detected by microarray and partially verified by qRT-PCR. GO and KEGG enrichment analysis was performed, and PPI protein interaction network was constructed to screen significant modules and hub genes.@*Results@#The expression of LOC102606465 targeted by siRNA-447 and siRNA-541 was significantly lower than that of siRNA-NC (t=29.095, 13.751, P<0.01). A total of 374 common DEGs were identified(112 up-regulated/262 down-regulated) in both siRNA-447 and siRNA-541. The qRT-PCR was used to validate the expression of DEGs, which was consistent with the microarray result. In GO enrichment analysis, down-regulated DEGs were significantly enriched in " oxidoreductase activity, acting on the CH-CH group of donors, NAD or NADP as acceptor" (molecular function), " basal lamina" (cellular component), " ammonium ion metabolic process" (biological process). Up-regulated DEGs were mainly enriched in " protein phosphatase inhibitor activity" (molecular function), " SNARE complex" (cellular component), " negative regulation of fibrinolysis" (biological process). In addition, the KEGG enrichment analysis revealed that DEGs were significantly enriched in " metabolism of xenobiotics by cytochrome P450" , " dorso-ventral axis formation" , " lysosome glycerophospholipid metabolism" and " p53 signaling pathway" . Based on the STRING database, the PPI network was constructed (including 194 nodes and 268 edges), and one significant module and five key hub genes ACTRT3, CDKN1A, DPYD, TMP4, and PRKACB were identified.@*Conclusions@#LOC102606465 could be a potential biomarker for the regulation of ionizing radiation sensitivity, and the down-regulation of LOC102606465 plays an important role in the response to radiation, which would be an important target for regulating radiation sensitivity.

ABSTRACT

Circular RNA is a kind of single-stranded RNA ring without 5'capping and 3'polyadenylation.As a new member of non-coding RNA, circular RNA is evolutionally conserved, relatively stable,highly specific and enormously abundant.Instead of liner RNA,circular RNA became the research hotspot.So far,cerebellar degeneration-related protein 1 antisense(CDR1as)is a molecule that has garnered intense research.CDR1as harbors 74 conventional miRNA-7 binding sites.Expression of CDR1as efficiently tethers micro RNA-7, resulting in reduced micro RNA-7 activity and increased levels of micro RNA-7 targeted transcripts consistent with the micro RNA sponge and competing endogenous RNA(ceRNA)hypothesis.Moreover,CDR1as can restore micro RNA-7 and release it at right time.CDR1as can be stabilized in the exosomes.And its level has correlation with many clinical characteristics.

ABSTRACT

It has been estimated that approximately 75% of the human genome is transcribed into RNA, 74% of which would be transcribed into non-coding RNA (ncRNA).The ncRNA can be divided into 2 major groups including small RNA and long non-coding RNA (lncRNA).There is increasing evidence that the dysregulation of lncRNA is closely associated with the occurrence and progression of many tumors.The lncRNA taurine up-regulated gene 1 (TUG1) is originally detected in a genomic screen for genes in response to taurine treatment of developing mouse retinal cells.According to research reports, dysregulation of TUG1 participates in the progression of a variety of tumors.Therefore, the regulatory effects of lncRNA TUG1 on tumorigenesis are summarized in this article.
