Abstract
Lung cancer, one of the most frequently diagnosed cancers, causes a huge number of mortalities globally. Among lung cancers, non-small cell lung cancer (NSCLC) is the most recorded. Despite accumulating research, the molecular basis of NSCLC progression remains poorly known. Therefore, we aim to assess the function of NCK1-AS1 in NSCLC and elucidate the molecular mechanism. Firstly, we quantified the NCK1-AS1 level in tumors and adjacent healthy tissues. NCK1-AS1 was significantly upregulated in NSCLC tumors, which was associated with poor prognosis in patients. Silencing NCK1-AS1 significantly inhibited the proliferation, migration, and invasion, as well as the EMT of NSCLC cell lines. Starbase bioinformatic prediction revealed that NCK1-AS1 targets miR-361-5p which acts to regulate ADAM10 gene expression. Our result showed that NCK1-AS1 upregulation markedly reduced miR-361-5p mRNA expression, while increasing ADAM10 expression. For the first time, we demonstrated that NCK1-AS1 regulates the miR-361-5p/ADAM10 axis, thereby promoting NSCLC progression. NCK1-AS1 might be developed as a therapeutic target for treating NSCLC.

Abstract
Objective: To determine the expression of LINC00958 (BLACAT2) in bladder cancer (BC), the most common malignancy in the urinary system, and to determine its exact mechanism of action, so as to provide novel references for future clinical diagnosis and treatment of BC and lay a foundation for the follow-up research on LINC00958. Materials and Methods: Human bladder transitional cell carcinoma cells (T24 and J82) and human normal urothelial cells (SV-HUC-1) were purchased to detect the expression of LINC00958 and SAPK/JNK signaling pathway-related proteins. sh-LINC00958 targeting to silence LINC00958 expression and corresponding negative blank (sh-Control) were transfected into T24 and J82. Additionally, BC cells cultured with SP600125 (SP600125 group), a specific inhibitor of SAPK/JNK signaling pathway, and those cultured with the same amount of normal saline (Blank group) were also constructed. Cell growth capacity, cell invasiveness, and expression of epithelial-mesenchymal transition (EMT)-associated proteins were determined using CCK-8 & clone formation assays, Transwell assay, and Western blot, respectively. Results: The online databases Gene Expression Profiling Interactive Analysis, European Bioinformatics Institute, and StarBase revealed elevated LINC00958 expression in BC, and a potential association between LINC00958 and patient prognosis and survival. PCR results showed that LINC00958 was increased in T24 and J82 compared with the sh-Control group (p < 0.05). The results of biological behavior test revealed that the proliferation and invasiveness capacity of the sh-LINC00958 group decreased, while that of the SP600125 group increased compared with the Blank group (both p < 0.05). In the rescue experiment, the influence of sh-LINC00958 on BC cells was completely reversed by SP600125 (p > 0.05); In addition, the expression of E-cadherin, an EMT marker protein, was lower compared with the SH-LINC0958 group, while the Vimentin expression was higher (p < 0.05). Similarly, the wound-healing assay determined reduced cell healing rate in the sh-LINC00958 group (p < 0.05), and there was no difference between the sh-LINC00958+SP600125 group and the sh-Control group (p > 0.05). Conclusion: LINC00958 shows elevated expression in BC and promotes the growth and EMT of BC cell via inhibiting the SAPK/JNK signaling pathway, which has important potential as a new clinical diagnostic marker and therapeutic target for BC.

Characterization of Infiltrating Immune Cells and Secretory or Membrane-Associated Proteins in KRAS Lung Adenocarcinoma. J Immunol Res 2023; 2023:4987832. [PMID: 36793588 PMCID: PMC9925262 DOI: 10.1155/2023/4987832] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2022] [Revised: 10/31/2022] [Accepted: 01/16/2023] [Indexed: 02/09/2023] Open
Abstract
Background This study identified the expression and prognosis significance of secretory or membrane-associated proteins in KRAS lung adenocarcinoma (LUAD) and depicted the characteristics between the immune cell infiltration and the expression of these genes. Methods Gene expression data of LUAD samples (n = 563) were accessed from The Cancer Genome Atlas (TCGA). The expression of secretory or membrane-associated proteins was compared among the KRAS-mutant, wild-type, and normal groups, as well as the subgroup of the KRAS-mutant group. We identified the survival-related differentially expressed secretory or membrane-associated proteins and conducted the functional enrichment analysis. Then, the characterization and association between their expression and the 24 immune cell subsets were investigated. We also constructed a scoring model to predict KRAS mutation by LASSO and logistic regression analysis. Results Secretory or membrane-associated genes with differential expression (n = 74) across three groups (137 KRAS LUAD, 368 wild-type LUAD, and 58 normal groups) were identified, and the results of GO and KEGG indicated that they were strongly associated with immune cell infiltrations. Among them, ten genes were significantly related to the survival of patients with KRAS LUAD. The expression of IL37, KIF2, INSR, and AQP3 had the most significant correlations with immune cell infiltration. In addition, eight DEGs from the KRAS subgroups were highly correlated with immune infiltrations, especially TNFSF13B. Using LASSO-logistic regression, a KRAS mutation prediction model based on the 74 differentially expressed secretory or membrane-associated genes was built, and the accuracy was 0.79. Conclusion The research investigated the relationship between the expression of KRAS-related secretory or membrane-associated proteins in LUAD patients with prognostic prediction and immune infiltration characterization. Our study demonstrated that secretory or membrane-associated genes were closely associated with the survival of KRAS LUAD patients and were strongly correlated to immune cell infiltration.

[PMID: 35569349 DOI: 10.1016/j.biopha.2022.113087] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2022] [Revised: 04/27/2022] [Accepted: 05/04/2022] [Indexed: 11/02/2022] Open
Abstract
Long non-coding RNAs (lncRNAs), a class of RNA transcripts longer than 200 nucleotides, do not encode proteins; however, they encode small peptides and micropeptides that act as bioactive peptides with notable effects in regulating the progression of malignant tumors, such as lung and colorectal cancers, and affecting patient prognosis. lncRNAs are important intracellular regulators, particularly in tumorigenesis and tumor progression. Long intergenic non-protein coding RNA958 (LINC00958), which has received increasing attention in recent years, is highly expressed in various malignancies, including head and neck squamous cell carcinoma (HNSC), non-small-cell lung cancer (NSCLC), gastric cancer, hepatocellular carcinoma (HCC), colorectal cancer, bladder cancer, and breast cancer. Here, we reviewed the recent studies on LINC00958 as well as its closely related clinical features and functional regulation in cancers. We systematically expounded the molecular mechanisms underlying the biological functions of LINC00958 in inhibiting cell apoptosis and enhancing the chemoradiotherapy resistance of tumor cells. The upregulation of LINC00958 enhances the resistance of tumor cells to radiotherapy and chemotherapy and induces lymphangiogenesis. Moreover, it is involved in tumor glycolytic metabolism, which plays a crucial role in facilitating the proliferation, invasion, and migration of tumor cells. Additionally, analysis of various studies revealed that LINC00958 acts as an endogenous competitive RNA (ceRNA) and regulates the malignant behavior of tumor cells through the miRNA-mRNA axis. Collectively, the use of LINC00958 as a novel biomarker and therapeutic target for the clinical diagnosis and treatment of different cancers has bright prospects in the future.
