Preclinical studies suggest that short-term fasting may be an effective tool for enhancing existing cancer therapies by disrupting the glucose-dependent, oncogenic phenotype of many cancers. In this study, we investigated whether a fasting-mimicking environment (FME) enhances the efficacy of an emerging proapoptotic drug, procaspase-activating compound 1 (PAC-1), in 2D and 3D GBM cell models. Ad libitum food consumption (Fed) and FME conditions were simulated <i>in vitro</i> by modifying glucose, ketone and serum concentrations. The FME conditions enhanced PAC-1 in U87-MG, T98G and 9L-GS monolayer experiments by significantly reducing the PAC-1 50% inhibitory concentration (IC<sub>50</sub>), delaying cell growth and increasing apoptosis. Similarly, in the 3D spheroid models, the minimum concentration of PAC-1 required to reduce U87-MG and 9L-GS spheroid area was lower in the FME conditions than the Fed conditions. Additionally, we discovered that serum restriction was primarily responsible for the FME-induced PAC-1 enhancement. These finding are the first to demonstrate that fasting-mimicking conditions sensitize 2D and 3D glioma cell models to PAC-1, supporting the use of short-term fasting as a low-cost and widely accessible strategy for enhancing cancer therapies.</p>","PeriodicalId":9686,"journal":{"name":"Cell Cycle","volume":" ","pages":"1-12"},"PeriodicalIF":3.9,"publicationDate":"2026-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12915821/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145988393","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Goosecoid (GSC), translated from a homeobox gene, is a protein participating in metastasis of assorted tumors. This study explores the role of GSC implicated in tumor metastasis, in PAAD progression. GSC expression in PAAD tissues and cells were tested by quantitative polymerase chain reaction (PCR) and western blot. GSC mRNA and protein expressions were elevated in PAAD tissues and cells. The impacts of GSC depletion or upregulation on PAAD cell proliferation, migration, invasion, cell cycle, and apoptosis were determined by colony formation assay, transwell assay, and flow cytometry. E-cadherin and N-cadherin expressions were tested through immunofluorescence to evaluate the epithelial-mesenchymal transition (EMT) process. The results showed that GSC depletion notably restrained cell proliferative and migratory capabilities and cell cycle, declined MMP2 and MMP9 activity, suppressed EMT process, and enhanced cell apoptosis. Nevertheless, GSC overexpression showed the opposite functions. Stem cell markers CD44 and CD133 were suppressed by GSC depletion and enhanced by GSC overexpression. Additionally, a sphere formation assay was implemented to test cell stemness. The levels of key proteins on TGF-β signaling were tested by western blot. GSC could activate TGF-β signaling in cells by promoting SMAD2/3 phosphorylation. The pathway inhibitor SIS3 notably counteracted the functions on cell malignant phenotypes induced by GSC overexpression. Moreover, xenograft tumor-bearing mouse models were established using male BALB/c nude mice to explore the effects of GSC knockdown on tumor growth and metastasis <i>in vivo</i>, and we found that GSC knockdown inhibited PAAD tumor growth and metastasis in xenograft models.

This approach enables precise quantification of TE transcripts at the locus level. By integrating p53 ChIP peaks with differentially expressed TE transcripts, we performed a global analysis of TE expression upon p53 binding. Applying this framework to lung fibroblast IMR90 and colon cancer HCT116 cells treated with p53 activators, we observed a striking pattern: TEs were predominantly activated in normal IMR90 cells but repressed in HCT116 cancer cells. Further analysis of 24 transcriptomes and 10 cistromes confirmed this trend as a distinguishing hallmark between normal and cancer cells. At the family level, normal cells showed broad TE upregulation, whereas cancer cells exhibited selective repression of Alu and LINE elements.
