However, the relationship between GRIM-19 and MDM2 in lung adenocarcinoma has not been reported yet.

Pearson correlation coefficient analysis showed a significant correlation between GRIM-19mRNA and MDM2mRNA (r = -0.970, <i>p</i> < 0.001). In this study, we further detected by experiments that the overexpression of GRIM-19 lowered the expression level of MDM2 protein, suggesting that GRIM-19 may affect the occurrence and development of lung adenocarcinoma by inhibiting the expression of MDM2. Cellular functional and subcutaneous tumour formation experiments in nude mice have shown that GRIM-19 inhibits the proliferation, invasion, and migration ability of lung adenocarcinoma cells, promotes cell apoptosis, and ultimately inhibits lung adenocarcinoma development. In addition, overexpression of GRIM-19 in A549 cells resulted in significant changes in the expression of EMT-related proteins Snail, N-Cadherin, E-Cadherin, and Vimentin, indicating that GRIM-19 may inhibit the metastasis of lung adenocarcinoma cells by regulating the EMT pathway.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10616-025-00797-5.</p>","PeriodicalId":10890,"journal":{"name":"Cytotechnology","volume":"77 4","pages":"130"},"PeriodicalIF":2.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12206682/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144539290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CAs are required for both physiological and pathophysiological processes such as cancer development, and there are differences in their expression profiles in different cancer types. Some members of the CA family like CAIX and CAXII have been suggested as potential cancer biomarkers in various studies. CAIX has been proposed as a possible biomarker for hypoxic colorectal carcinoma. Expression of CAIII, another member of the CA family, was also found to be reduced by TGF-β via the MAPK and PI3K signaling pathways in human colon cancer cells. Additionally, not much is known regarding the interaction between TNF-α, inflammation-related cytokine, and CAIII in colorectal carcinoma (CRC). This study investigates the effect of TNF-α on CAIII expression in different cancer cells, namely HT-29 and Saos-2. CAIII mRNA expression was analyzed by qRT-PCR at both late (24, 48, and 72 h) and early time points (1, 3, and 6 h). Western blot analysis was also used to confirm the reducing effect of TNF-α at the CAIII protein level. To analyze the transcriptional regulation of CAIII by TNF-α, CAIII promoter constructs were transiently transfected to HT-29 and Saos-2 cells, and transcriptional activities of truncated promoter constructs were analyzed with luciferase/SEAP activities. 500U/mL TNF-α led to a drastic decrease at 24 and 48 h time points at CAIII mRNA level. Western blot analysis showed that this decreasing effect of 500 U/mL TNF-α at 24 h, 48 h, and 72 h resulted in a reduction of the CAIII protein level by 0.5 times.

Transcriptional activity of all CAIII promoter constructs was reduced by TNF-α. As a result of pathway inhibition analysis, we deduce that TNF- α decreases CAIII mRNA expression in a colon cancer cell via the PI3K pathway.

Recent research suggests that drugs that induce ferroptosis could treat osteosarcoma. It is unknown how erastin-induced ferroptosis influences differential gene expression of System Xc, iron absorption, heme synthesis, and mono- (MUFA) and polyunsaturated (PUFA) fatty acid levels in aggressive OS cells. In this study, we show that erastin-induced ferroptosis decreases OS cell growth and survival by raising total ROS, mitochondrial membrane potential, and downregulating <i>VDAC2</i>. Furthermore, erastin induces elevated levels of <i>SLC7A11</i> and <i>SLC3A2</i>, but downregulation of <i>TFRC</i> and <i>HMOX1</i> in OS cells. Notably, the addition of Ferrostatin-1 protects against Erastin-induced cytotoxicity, implying that these agents induce ferroptosis. We also showed that Ferrostatin-1 provides partial protection against Erastin-induced ferroptosis by stimulating the unique transcriptional gene profile of System Xc-, MUFA, and PUFA while inhibiting iron uptake and heme production in OS cells. These findings show that Erastin inhibits the survival of aggressive OS cells, but it also increases the expression of genes linked with anti-ferroptosis activity, which could lead to preventing ferroptosis in the aggressive OS phenotype.

HNSCC cells were treated with 50-1000 μM AloAB to assess dose-dependent cytotoxicity and its effects on the STAT3/SLC7A11 pathway. CRISPR activation plasmids were used to overexpress STAT3 or SLC7A11 in FaDu cells. Subsequent analyses included migration and invasion assays, lipid peroxidation (LPO) assay, intracellular iron assay, as well as the measurement of oxidative stress markers and ferroptosis-related factors. Epithelial-mesenchymal transition (EMT) markers and matrix metalloproteinase (MMP) expression levels were also assessed. AloAB treatment significantly reduced cell viability in HNSCC cells at higher concentrations. It inhibited FaDu cell proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT), while downregulating STAT3/SLC7A11 expression. Additionally, AloAB induced oxidative stress and ferroptosis, as indicated by elevated malondialdehyde (MDA), Acyl-CoA Synthetase Long-Chain Family Member 4 (ACSL4), lipid peroxidation (LPO), and iron levels, alongside decreased levels of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase 4 (GPX4), reduced glutathione (GSH), and glutathione peroxidase (GPx). Overexpression of STAT3 or SLC7A11 reversed these effects, restoring oxidative stress markers and ferroptosis-related factors to control levels. Moreover, the suppression of EMT was alleviated by the upregulation of E-cadherin and the downregulation of N-cadherin, Vimentin, MMP2, and MMP9. AloAB exerts anti-tumor effects on HNSCC cells by inhibiting the STAT3/SLC7A11 signaling pathway, inducing oxidative stress, ferroptosis, and suppression of migration, invasion, and EMT.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10616-025-00798-4.</p>","PeriodicalId":10890,"journal":{"name":"Cytotechnology","volume":"77 4","pages":"137"},"PeriodicalIF":2.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12229470/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144575007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
