Xie K, Chen Z, Feng J, Pan L, Wang N, Luo J, Yao Y, Ma H, Feng Y, Jiang W. Identification and validation of prognostic and immunotherapeutic responses in esophageal squamous carcinoma based on hypoxia phenotype-related genes. Front Pharmacol 2024; 15:1344317. [PMID: 38515846 PMCID: PMC10955338 DOI: 10.3389/fphar.2024.1344317] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Accepted: 02/21/2024] [Indexed: 03/23/2024] Open
Abstract
The study aimed to investigate the clinical significance of the interaction between hypoxia and the immune system in esophageal squamous cell carcinoma (ESCC) microenvironment. A comprehensive evaluation of 13 hypoxia phenotype-related genes (HPRs) was conducted using data from TCGA-ESCC and two GEO cohorts. Three distinct HPRclusters were identified, and the HPRscore was established as an independent prognostic factor (p = 0.001), with higher scores indicating poorer prognosis. The HPRscore was validated in various immunotherapy cohorts, demonstrating its efficacy in evaluating immunotherapy and chemotherapy outcomes. Additionally, phenome-wide association study (PheWAS) analysis showed that PKP1 had no significant correlation with other traits at the gene level. PKP1 was identified as a potential prognostic marker for ESCC, with upregulated expression observed in ESCC patients. In vitro experiments showed that the knockdown of PKP1 inhibited ESCC cell proliferation and migration. These findings suggest that the novel HPRscore and PKP1 may serve as prognostic tools and therapeutic targets for ESCC patients.

Abstract
In this paper, LINC00839 expression in gastric cancer (GC) was confirmed by real-time quantitative PCR. The function of LINC00839 in GC was detected by loss of function assays. Luciferase assays was performed to confirm the interaction between LINC00839 and miR-1236-3p. Then we investigated the regulatory effect of LINC00839 on miR-1236-3p. The results confirmed that the expression level of LINC00839 in GC was significantly up-regulated. LINC00839 could promote GC cell proliferation, mobility, and invasion. The detection of luciferase reporter gene confirmed that LINC000839 could bind to the binding site of miR-1236-3p. Our findings suggest that LINC00839 promotes GC progression through sponging miR-1236-3p.
