This work aims to explore role of CDC25B in cisplatin sensitivity in stomach adenocarcinoma and offer a possible mechanism for explaining its function. By using bioinformatics approaches, CDC25B and TEAD4 expression levels in stomach adenocarcinoma tissues and enriched pathways of CDC25B were analyzed. qRT-PCR of CDC25B and TEAD4 expression in stomach adenocarcinoma cells, CCK-8 detection of cell viability and IC 50 values, and colony formation assay on cell proliferation were performed. Cell adhesion experiment detected cell adhesion ability. Western blot detected expression of proteins related to cell adhesion, specifically Muc-1, ICAM-1, VCAM-1. Dual luciferase assay and ChIP experiment verified binding relationship between TEAD4 and CDC25B. CDC25B was upregulated in stomach adenocarcinoma tissues and cells, enriched in focal adhesion pathway. Treatment with cell adhesion inhibitors revealed that CDC25B overexpression inhibits the sensitivity of stomach adenocarcinoma to cisplatin through the cell adhesion pathway. CDC25B has an upstream transcription factor TEAD4, which targeted and bound to CDC25B and was highly expressed in stomach adenocarcinoma. Rescue experiment revealed that knocking down TEAD4 weakened suppressive impact of CDC25B overexpression on sensitivity of stomach adenocarcinoma cells to cisplatin. Transcription factor TEAD4 could activate the transcription of CDC25B through cell adhesion to drive cell invasion and reduce sensitivity of stomach adenocarcinoma to cisplatin.

The protumor activities of cancer-associated fibroblasts (CAFs) suggest that they are potential therapeutic targets for cancer treatment. There is, however, a lack of CAF-related signature in predicting response to immunotherapy in gastric cancer (GC). Single-cell RNA sequencing (scRNA-seq) and RNA sequencing (RNA-seq) data of GC immunotherapy were downloaded from the Gene Expression Omnibus database. Bulk RNA-seq data were obtained from The Cancer Genome Atlas. The R package 'Seurat' was used for scRNA-seq data processing. Cellular infiltration, receptor-ligand interactions, and evolutionary trajectory analysis were further explored. Differentially expressed genes affecting overall survival were obtained using the limma package. Weighted Gene Correlation Network Analysis was used to identify key modules of immunotherapy nonresponder. Prognostic model was constructed by univariate Cox and least absolute contraction and selection operator analysis using the intersection of activated fibroblast genes (AFGs) with key module genes. The differences in clinicopathological features, immune microenvironment, immunotherapy prediction, and sensitivity to small molecule agents between the high- and low-risk groups were further investigated. Based on scRNA-seq, we finally identified 20 AFGs associations with the prognosis of GC patients. AFGs' high expression levels were correlated with both poor prognosis and tumor progression. Three genes ( FRZB , SPARC , and FKBP10 ) were identified as immunotherapy nonresponse-related fibroblast genes and used to construct the prognostic signature. This signature is an independent significant risk factor affecting the clinical outcomes of GC patients. Remarkably, there were more CD4 memory T cells, resting mast cells, and M2 macrophages infiltrating in the high-risk group, which was characterized by higher tumor immune exclusion. Moreover, patients with higher risk scores were more prone to not respond to immunotherapy but were more sensitive to various small molecule agents, such as memantine. In conclusion, this study constructed a fibroblast-associated ICI nonresponse gene signature, which could predict the response to immunotherapy. This study potentially revealed a novel way to overcome immune resistance in GC.</p>","PeriodicalId":7969,"journal":{"name":"Anti-Cancer Drugs","volume":" ","pages":"952-968"},"PeriodicalIF":1.8,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141896582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previously, we found that BAP1 loss renders RCC cells more sensitive to bromodomain and extra-terminal (BET) inhibitors, as demonstrated in both cell culture and xenografted nude mice models. Here, we demonstrate that BAP1 loss in murine RCC cells enhances sensitivity to BET inhibitors in ectopic and orthotopic allograft models. While BAP1 deletion suppresses RCC cell survival in vitro , it does not impede tumor growth in immunocompetent murine models. Thus, the effect of BAP1 loss on the interactions between tumor cells and host microenvironment plays a predominant role in RCC growth, highlighting the importance of utilizing immunocompetent animal models to assess the efficacy of potential anticancer therapies. Mechanistically, BAP1 deletion compromises DNA repair capacity, rendering RCC cells more vulnerable to DNA damage induced by BET inhibitors.

This study was intended to explore the role of PLA2G16 in multiple myeloma and to reveal the reaction mechanism. The mRNA and protein expressions of PLA2G16 in human bone marrow stromal cell line HS-5 and multiple myeloma cells were assessed using reverse transcription-quantitative PCR and western blot. The transfection efficacy of sh-PLA2G16 and oe-YAP was examined using reverse transcription-quantitative PCR and western blot. Through cell counting kit-8 assay and 5-ethynyl-2'- deoxyuridine staining, multiple myeloma cell viability and proliferation were detected. Flow cytometry was used to measure cell apoptosis and cell cycle distribution. Oxygen consumption rate, the activities of mitochondrial respiratory chain complexes I-V, and the activity of caspase-3 were estimated with Seahorse XF24 analyzer, oxidative phosphorylation activity assay kit, and caspase-3 assay kit, respectively. Lactate production and glucose consumption were evaluated usingcorresponding assay kits. Western blot was employed to meaure proteins associated with cell cycle, glycolysis, pentose phosphate pathway as well as Hippo/YAP signaling pathway. In this study, PLA2G16 expression was greatly increased in multiple myeloma cells and PLA2G16 silence inhibited cell proliferation, promoted cell apoptosis, facilitated cell cycle arrest, and suppressed the reprogramming of glucose metabolism in multiple myeloma. It was also identified that PLA2G16 depletion inhibited the Hippo/YAP signaling pathway. Further experiments revealed that the overexpression of YAP partially reversed the inhibitory effects of PLA2G16 silence on multiple myeloma cell malignant development and the reprogramming of glucose metabolism.
