Abstract To confirm the relationship between Circ_0003855 and EC, we purchased the Human esophageal carcinoma cell line Eca109 and normal human esophageal epithelial cells HEEC, and the expression levels of Circ_0003855, miR-622, and FLOT1 were detected. The results show that Circ_0003855 and FLOT1 were highly expressed in Eca109 cells, while miR-622 was lowly expressed (p < 0.05). Subsequently, Circ_0003855 small interfering RNA (si-Circ_0003855) and its negative control (si-NC) were used to detect changes in cellular biological behaviors. We found that the activity of Eca109 cells was reduced after interfering with the expression of Circ_0003855, and miR-622 expression was elevated, while FLOT1… More >

Abstract Objective: Previous studies indicated that aberrant circular RNA (circRNA) expression affects gene expression regulatory networks, leading to the aberrant activation of tumor pathways and promoting tumor cell growth. However, the expression, clinical significance, and effects on cell propagation, invasion, and dissemination of circRNA_001896 in cervical cancer (CC) tissues remain unclear. Methods: The Gene Expression Omnibus (GEO) datasets (GSE113696 and GSE102686) were used to examine differential circRNA expression in CC and adjacent tissues. The expression of circRNA_001896 was detected in 72 CC patients using fluorescence quantitative PCR. Correlation analysis with clinical pathological features was performed through COX multivariate and univariate analysis.… More >

Abstract Background: Placenta specific 8 (PLAC8) is a candidate oncogene involved in the development and progression of solid tumors. However, the status of PLAC8 in lung cancer (LC), especially non-small cell lung cancer (NSCLC) is still not lucid. Methods: Tissue microarray analysis (TMA) was performed to detect the expression patterns of PLAC8 in LC tissues and cell lines. Then a series of cellular experiments were performed fto assess cell proliferation, cell cycle profiles, and cell motility to explore the role of PLAC8 in NSCLC-derived cell lines: H1299 and A549. Results: TMA results showed that PLAC8 played complex and even contradictory roles… More >

Abstract Genetic information is transcribed from genomic DNA to mRNA, which is then translated into three-dimensional proteins. mRNAs can undergo various post-transcriptional modifications, including RNA editing that alters mRNA sequences, ultimately affecting protein function. In this study, RNA editing was identified at the 499th base (c.499) of human vaccinia-related kinase 2 (VRK2). This RNA editing changes the amino acid in the catalytic domain of VRK2 from isoleucine (with adenine base) to valine (with guanine base). Isoleucine-containing VRK2 has higher kinase activity than the valine-containing VRK2, which leads to an increase in tumor cell proliferation. Earlier we reported that VRK2 directly interacts… More > Graphic Abstract

Abstract Background: Glioma is the most common primary brain tumor. Exploration of new tumorigenesis mechanism of glioma is critical to determine more effective treatment targets as well as to develop effective prognosis methods that can enhance the treatment efficacy. We previously demonstrated that the deubiquitinase biquitin carboxyl-terminal hydrolase L5 (UCHL5) was downregulated in human glioma. However, the effect and mechanism of UCHL5 on the proliferation of glioma cells remains unknown. Methods: Transfection of siRNA was used to knockdown the expression of UCHL5 in U251 cells. The 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay, Edu assay, and colony formation assay were employed to… More > Graphic Abstract

Abstract Fos-related antigen 1 (Fra-1) is a nuclear transcription factor that regulates cell growth, differentiation, and apoptosis. It is involved in the proliferation, invasion, apoptosis and epithelial mesenchymal transformation of malignant tumor cells. Fra-1 is highly expressed in gastric cancer (GC), affects the cycle distribution and apoptosis of GC cells, and participates in GC occurrence and development. However, the detailed mechanism of Fra-1 in GC is unclear, such as the identification of Fra-1-interacting proteins and their role in GC pathogenesis. In this study, we identified tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein eta (YWHAH) as a Fra-1-interacting protein in GC cells using co-immunoprecipitation… More >

Abstract Background: Vascular smooth muscle cells (VSMCs) undergo a conversion from a contractile phenotype to a proliferative synthetic phenotype, contributing to the pathogenesis of cardiovascular diseases. Semaphorin 7A (SEMA7A) is a glycosylphosphatidylinositol-anchored membrane protein that plays an important role in vascular homeostasis by regulating endothelial cell behaviors. However, the expression and role of SEMA7A in VSMCs remain unclear.Methods: In this study, we screened for VSMC-regulating genes in publicly available datasets and analyzed the expression of SEMA7A in human coronary artery smooth muscle cells (hCASMCs) treated with platelet-derived growth factor-BB (PDGF-BB). The effects of SEMA7A overexpression and knockdown on hCASMC proliferation and… More >

Abstract The Wnt/β-catenin signaling pathway is the main target of tooth regeneration regulation. Treatment of cells with AZD2858 stimulates the Wnt/β-catenin signaling pathway, yet the function of this pathway in tooth regeneration remains unclear. Here, we found that AZD2858 promotes the accumulation of β-catenin in the nuclei of stem cells from the apical papilla (SCAPs) and enhances cell proliferation. Single-cell sequencing was performed on SCAPs treated with AZD2858. Eight clusters were identified, namely SCAPs-CNTNAP2, SCAPs-DTL, SCAPs-MYH11, SCAPs-MKI67, SCAPs-CXCL8, SCAPs-TPM2, SCAPs-IFIT2 and SCAPs-NEK10. The pseudo-time trajectory analysis showed that AZD2858 enhanced the evolution of SCAPs from SCAPs-TMP2 clusters to SCAPs-MYH11, SCAPs-CNTNAPs and… More >

Abstract Background: Activated hepatic stellate cells (HSCs) are closely involved in the initiation, perpetuation, and resolution of liver fibrosis. Pro-inflammatory cytokine levels are positively correlated with the transition from liver injury to fibrogenesis and contribute to HSC pathophysiology in liver fibrosis. Methods: In this study, we investigated the effect of the pro-inflammatory cytokine interleukin (IL)-1β on the proliferation and signaling pathways involved in fibrogenesis in LX-2 cells, an HSC cell line, using western blotting and cell proliferation assays. Results: IL-1β increased the proliferation rate and α-smooth muscle actin (SMA) expression of LX-2 cells in a dose-dependent manner. Within 1 h after… More >

Abstract Background: MicroRNA-145-5p (miR-145-5p) reportedly inhibits hepatocellular carcinoma (HCC) by targeting ARF6, SPATS2, CDCA3, KLF5, and NRAS, indicating that miR-145-5p plays an important role in the occurrence and development of HCC by regulating the expression of various genes. In this study, we aimed to explore novel downstream targets of miR-145-5p and elucidate the potential mechanism of miR-145-5p in HCC. Materials and Methods: A bioinformatics analysis was performed to determine the clinical significance of miR-145-5p and alpha/beta hydrolase domain-containing protein 17C (ABHD17C) in patients with HCC. The ability of Hep3B cells to proliferate, migrate, and invade was examined after overexpression of miR-145-5p… More >
