HeLa (HPV18-positive) and CaSki (HPV16-positive) cells were exposed to various concentrations of AST. CCK-8 assay, flow cytometry analysis, wound healing, and Transwell assays were employed to examine the AST functions on CC cell aggressiveness. Protein levels were assessed by western blotting. Immunofluorescence staining was used to detect E6, E7, p53, and p-pRb expression. Animal experiments were performed to validate the anti-CC role in vivo. The results showed that AST dose-dependently impaired HeLa and CaSki cell viability and elicited G1 cell cycle arrest. AST restrained CC cell migration and invasiveness. AST inhibited the growth of HeLa-derived xenograft tumors in mice and repressed E6/E7 oncoprotein expression in CC cells and mouse tumor tissues. In conclusion, AST suppresses CC progression by downregulating E6/E7 oncoprotein expression to attenuate CC cell aggressiveness.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10616-025-00742-6.</p>","PeriodicalId":10890,"journal":{"name":"Cytotechnology","volume":"77 3","pages":"80"},"PeriodicalIF":2.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11923324/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143691479","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}

Cartilage organoids serve as a physiologically relevant model for studying cartilage development, disease progression, and regeneration. By integrating PRP with cartilage organoids, this review aims to enhance chondrogenesis, extracellular matrix synthesis, and cellular proliferation within the organoids. Emerging evidence suggests that PRP supplementation significantly improves chondrocyte viability, growth, and differentiation in cartilage organoids, thereby accelerating their maturation. This combination holds great potential for advancing cartilage repair strategies, providing a robust platform for preclinical studies, and paving the way for innovative therapeutic approaches for cartilage-related injuries and degenerative diseases. These key aspects-chondrogenesis, matrix synthesis, and cellular proliferation-were specifically selected due to their fundamental roles in cartilage tissue engineering and regeneration. Chondrogenesis is crucial for chondrocyte differentiation and maintenance, matrix synthesis ensures the structural integrity and functional properties of regenerated cartilage, and cellular proliferation supports tissue viability and repair. Addressing these factors is essential, as current cartilage regeneration strategies often suffer from limited long-term efficacy and inadequate extracellular matrix production.

However, functions and mechanisms of CTHRC1 in children with IBD remain unclear. This study aimed to determine the effects and mechanisms of CTHRC1 on dextran sodium sulfate (DSS)-treated HT-29 cells. HT-29 control cells were exposed to 2% DSS to develop an in vitro IBD model. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blotting were used to assess CTHRC1 expression in serum of children with IBD and HT-29 cells. Cell viability and apoptosis were assessed using MTT and flow cytometry (FCM). Expressions of cleaved-Caspase3 and Caspase3 were determined by western blotting. The cytokine production (TNF-α, IL-1β and IL-6) in HT-29 cells was measured by ELISA assay. Activation or inactivation of NF-κB signaling pathway was confirmed by western blot assay. Results showed that CTHRC1 expression was upregulated in the IBD serum and HT-29 control cells. The level of CTHRC1 was lower in CTHRC1-siRNA transfected cells than in control siRNA-treated cells. Notably, silence of CTHRC1 markedly enhanced HT-29 cells viability, decreased apoptotic cells, suppressed cleaved-Caspase3 expression, inhibited cleaved-Caspase3/Caspase3 ratio, reduced the production of inflammatory cytokines, and blocked NF-κB signaling pathway induced by DSS.
