Keratin 23 (KRT23), a member of the keratin family, is implicated in the development of various cancers. Hence, this study aimed to clarify the molecular mechanism of KRT23 in the progression of CRC. Quantitative real time polymerase chain reaction (qRT-PCR) and western blot were applied to detected RNA and protein levels. Cell migration, invasion, and apoptosis were measured by wound healing, transwell assay, and flow cytometry, respectively. Glycolysis was reflected by the detection of ATP, lactate production, and glucose consumption. What's more, the binding site of zinc finger protein 384 (ZNF384) and KRT23 was predicted using the relevant website and verified by chromatin immunoprecipitation (CHIP) and dual-luciferase reporter assay. Meanwhile, the related proteins were detected by immunohistochemistry (IHC). A mouse xenograft model was established for in vivo analysis and further verified the role of ZNF384 and KRT23 in CRC. KRT23 was highly expressed in CRC tissues and cells. Functionally, silencing KRT23 inhibited CRC migration and invasion, promoted apoptosis, and impeded epithelial-mesenchymal transition (EMT) and glycolysis process by the TGF-β/Smad signaling pathway. In terms of mechanism, ZNF384 bound to the KRT23 promoter, and the inhibition caused by ZNF384 interference was reversed with KRT23. In vivo, knocking down ZNF384 inhibited tumor growth. In summary, ZNF384 could promote the malignant progression of CRC by regulating the KRT23-mediated TGF-β/Smad signaling pathway.</p><p><strong>Supplementary information: </strong>The online version contains supplementary material available at 10.1007/s10616-025-00765-z.</p>","PeriodicalId":10890,"journal":{"name":"Cytotechnology","volume":"77 3","pages":"111"},"PeriodicalIF":2.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12125435/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144198419","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}

In this study, we describe a method combining enzymatic and mechanical dissociation of large spheroids of five different oral squamous cell carcinoma (OSCC) cell lines (H314, SCC9, SCC25, UM-SCC1 and HSC3). Spheroids were generated using magnetic 3D bioprinting. Efficacy of dissociation and viability after dissociation were evaluated by flow cytometry. All spheroids were successfully dissociated into single cells with low cell aggregation using this method, except for spheroids of HSC3 cells. H314 and SCC9 spheroids yielded the highest number of events per microliter and therefore also the largest total number of events. H314 and SCC25 spheroids presented the better results for cell viability after dissociation. H314 spheroids also gave the largest total number of viable cell events.

The aim of this study was to investigate the role and mechanism of IGFBP7 in a cellular model of LPS-induced IDD. Human primary NP cells were cultured, and subsequently, LPS-stimulated human NP cells were employed to establish an IDD cell model. RT-qPCR and western blot assay were conducted to assess the expression of IGFBP7 in NP cells. A small interfering RNA targeting IGFBP7 (IGFBP7-siRNA) was used to explore the role of IGFBP7 in LPS-treated human NP cells. The viability and apoptosis levels of these cells were then evaluated using MTT assay and flow cytometry analysis. The secretion of TNF-α, IL-6, and IL-1β was calculated by ELISA. RT-qPCR and western blot assay were also utilized to measure the expression levels of Bax, Bcl-2, aggrecan, and type II collagen. Furthermore, western blot analysis was employed to detect the phosphorylation levels of ERK1/2 proteins. To explore the role of the ERK1/2 pathway in NP cells, LM22B-10, an ERK activator, was applied. IGFBP7 expression was significantly elevated in LPS-stimulated human NP cells to approximately 3 folds of control levels. LPS significantly inhibited the viability of human NP cells and promoted the level of apoptosis and inflammatory factor secretion. LPS markedly induced the expression of Bax in human NP cells, while suppressed the abundance of Bcl-2, aggrecan, and collagen type II. LPS significantly activated the ERK1/2 pathway in human NP cells, promoting an increase in ERK1/2 phosphorylation levels. All of these phenomena were reversed by IGFBP7-siRNA. LM22B-10 could significantly reverse the effects of IGFBP7-siRNA on LPS-induced human NP cells.

The supply interruption for the cell culture medium ActiPro™ optimized for producing VRC01, an IgG1-κ mAb, from a CHO-K1 cell line, necessitated the search for alternate media. VRC01 mAb is highly glycosylated and can broadly neutralize several strains of Human Immunodeficiency Virus (HIV). We investigated to see if an alternate medium can be used in the production without impacting quality attributes like glycosylation. In our strategy, we used 3 different commercially available media, performed two sets of experiments-with and without media supplements, Cell boost 7a and Cell boost 7b. Cell growth, volumetric production of the mAb protein and glycosylation pattern were compared to identify an alternative medium. Among the tested media based on cell growth, mAb production potential and glycosylation analysis, ActiCHO™ P was found to be a better alternate medium to ActiPro™ medium than EX-CELL® 325 PF CHO medium to produce VRC01 mAb.
