Abstract Psoriasis is an autoimmune-related chronic inflammatory disease with an approximate prevalence of 2–3% around the world, involving increased keratinocyte proliferation. Indeed, Th17 cells and IL-17 play critical roles in the pathogenesis of psoriasis. The monoclonal antibodies against cytokines have been shown to have effectively immunosuppressive effects on human psoriasis. However, there are still some patients that have no response to these treatments. Some patients have even serious side-effects which may affect their life. Mesenchymal stem cells have the ability of immunosuppressive and anti-inflammatory effects, which may be an alternative therapy with more safety and efficacy for human psoriasis. Moreover, the… More >

Abstract The chemokine ligand 13-chemokine receptor 5 (CXCL13-CXCR5) axis has been characterized as a critical tumor-promoting signaling pathway in the tumor microenvironment (TME) in multiple types of solid tumors. In this study, we analyzed the expression profile of CXCL13 in kidney clear cell carcinoma (KIRC) and its correlation with tumor-infiltrating immune cells (TIICs). A monoclonal antibody against CXCL13 with high affinity and purity was generated in our lab for western blot and immunohistochemistry (IHC). Bioinformatic analysis was performed based on bulk-seq data from the Cancer Genome Atlas (TCGA)-KIRC and single-cell RNA-seq data from scRNASeqDB and PanglaoDB. Results showed that high CXCL13… More >

Abstract Tet methylcytosine dioxygenase 2 (TET2) acts as an antioncogene that is investigated in different cancers. But the effects of TET2 in renal cell cancer (RCC) is still known little. Here, quantitative real-time PCR (qRT-PCR), Western blot, and immunofluorescence were performed to exam gene and protein expression. Cell proliferation was measured using Cell Counting Kit-8 (CCK-8). Transwell assay was performed to detect cell metastasis viability. Flow cytometry was performed to analyze the cell cycle and cell apoptosis. The effects of TET2 on RCC growth in vivo was analyzed using a mouse xenograft model.We found that TET2 and miR-200c were decreased in… More >

Abstract Chemotherapy drug resistance is the main cause leading to the relapse and metastasis of non-small cell lung cancer (NSCLC) patients. Our study aimed to investigate the mechanism of pemetrexed resistance in NSCLC. Firstly, the pemetrexed (PEM)-resistant PC-9 and A549 lung adenocarcinoma cell lines (PC-9/PEM and A549/PEM) were established. The expression of thymidylate synthase (TS) in PC-9/PEM, A549/PEM, A549, and PC-9 cells were analyzed by qRT-PCR and western blot. Then, cell viability, colony formation, migration, and invasion were performed on PEM-resistant cells transfected with TS siRNA. The role of EGFR in PEM resistance of PEM-resistant cells was investigated using EGFR siRNA.… More >

Abstract Increasing evidence indicates that aberrant expressions of some microRNAs are associated with cancer progression. However, the roles and biological mechanisms of miRNA-16-5p in human non-small cell lung cancer (NSCLC) are not to be well studied. Here, we validated that the expression of miR-16-5p was decreased significantly in NSCLC samples and cell lines. The correlation between the clinicopathological features of NSCLC and the miR-16- 5p expression showed that the expression of miR-16-5p in non-small cell lung cancer was linked with the advanced TNM stage, positive lymph node metastasis, with short overall survival (OS). Also, a negative correlation between miR-16-5p and Fermitin… More >

Abstract Non-small cell lung cancer (NSCLC) cells intake and consume glucose at high efficiency by aerobic glycolysis to maintain robust cell growth and resist cell death. MicroRNAs (miRNAs) have been known to play pivotal roles in NSCLC development partly through mediating glycolysis. However, only a few miRNAs have been experimentally confirmed as critical regulators of glycolysis in NSCLC. TCGA datasets were analyzed to screen for differentially expressed miRNAs between NSCLC and normal tissues. The function of miR-1294-5p was determined in NSCLC cells by cell proliferation, glucose uptake, lactate release, and Extracellular Acidification Rate (ECAR) assays. The target of miR- 1294-5p was… More >

Abstract Reviews The Dectin-1 cluster comprises seven members: CLEC-12A, CLEC-12B, CLEC-1A, CLEC-7A, CLEC- 2, CLEC-9A and OLR1. These members have been demonstrated to be involved in the tumorigenesis, progression, and metastasis of several cancers. However, little is known about their roles in human lung adenocarcinoma (LUAD). The expression patterns of the Dectin-1 cluster were analyzed via the ONCOMINE and GEPIA databases. We evaluated the prognostic value of the Dectin-1 cluster in patients with LUAD using the Kaplan-Meier plotter and GEPIA. Differential expression was validated with the EMBL-EBI database, and protein expression was analyzed with the HPA database. In addition, protein-protein interaction… More >

Abstract Esophageal cancer is the second most common type of cancer after lung carcinoma in the state of Jammu and Kashmir (J&K). The understanding of genetics in Esophageal cancer development is poor in the state. Genome wide association studies (GWAS) has proved to be unsurpassed tool in identification of new loci associated with different cancers. GWAS in Chinese population has identified SNP rs2294693 present in UNC5CL (UNC-5 Family C-Terminal like) to be associated with non-cardia gastric cancer. We performed a case control association study and genotyped the SNP rs2294693 using Taqman allele discrimination assay in 566 individuals (166 esophageal cancer patients… More >

Abstract Hypoxia affects the advancement, metastasis, and metabolism of breast cancer (BC). The circular RNA ribonuclease P RNA component H1 (circRPPH1) (has_circ_0000515) is implicated in tumor progression. Nevertheless, the regulatory mechanism related to circRPPH1 in hypoxia-mediated triple-negative breast cancer (TNBC) progression is indistinct. The expression levels of circRPPH1, miR-1296-5p, tripartite motif-containing 14 (TRIM14) mRNA in tissue samples and cells were examined through quantitative real-time polymerase chain reaction (qRT-PCR). Cell viability, migration, and invasion were determined with Cell Counting Kit-8 (CCK-8) or transwell assays. The levels of glucose consumption and lactate production were assessed via the Glucose Assay Kit or Lactate Assay… More >

Abstract RPA3 (Replication Protein A3) (14 kD) is a part of the canonical heterotrimeric replication protein A complex (RPA/RP-A). This study aimed to explore the functional role of RPA3 and the mechanisms of its dysregulation in breast cancer. Data from the Cancer Genome Atlas (TCGA)-breast cancer patients and GSE75688 were utilized for gene expression and survival analysis. Breast cancer cell lines MDA-MB-231 and SK-BR-3 were used for in-vitro cell studies. Clonogenic assay and immunofluorescent staining of γ-H2AX were performed to examine radiation-induced cytotoxicity. Systemic correlation analysis was performed to identify potential transcription factors (TFs) regulating RPA3 expression. ChIP-qPCR and dual-luciferase assay… More >
