It is closely associated with the dysfunction of glomerular endothelial cells (GECs) under hyperglycemia. Severe inflammation is an important inducer for the development of GECs dysfunction, and it contributes to the disruption of tight junctions in GECs and the increased endothelial permeability. Sinomenine, an alkaloid monomer extracted from the rhizome of Sinomenium acutum, is recognized for its multiple pharmacological functions, including an anti-DN property. The present study aimed to explore the potential functional mechanism of Sinomenine against DN. Animals were randomly divided into Sham, DN, DN + Sinomenine (20 mg/kg), and DN + Sinomenine (40 mg/kg) groups. The Sinomenine or vehicle was administered every day for 6 weeks, followed by collecting renal tissues for further detection. Increased body weights, elevated blood glucose levels and UAE values, aggravated renal tissue pathology, higher concentrations of IL-18 and IL-1β in renal tissues, and reduced claudin-5 expression were observed in DN rats. However, the administration of Sinomenine significantly alleviated all these DN-related changes. Furthermore, human renal glomerular endothelial cells (HrGECs) were treated with high glucose (HG, 30 mM) with or without Sinomenine (50, 100 μM) for 24 h. We found that Sinomenine treatment ameliorated the elevated production of IL-18 and IL-1β, increased fluorescence intensity of FITC-dextran, declined trans-endothelial electrical resistance (TEER) value, and reduction of claudin-5 and C/EBP-α in HG-treated HrGECs. Moreover, the regulatory effect of Sinomenine on endothelial monolayer permeability in HG-treated HrGECs was abolished by the knockdown of C/EBP-α, indicating C/EBP-α is required for the effect of Sinomenine.

The expression of mRNA and protein was evaluated by real-time qPCR, western blotting, immunofluorescent, and immunohistochemical staining. TMEM97 functions in cell proliferation, apoptosis, migration, and invasion were assessed by CCK-8, flow cytometry, and transwell assays. The roles of TMEM97 in CRC cells in vivo was investigated using a subcutaneous xenograft model. The transcriptional regulation of TMEM97 was explored by luciferase reporter and ChIP assays. The silencing of TMEM97 inhibited migration and invasion of CRC cells in vitro and led to suppressed growth and enhanced apoptosis in CRC cells and xenografts, whereas overexpression of TMEM97 displayed opposite effects. Mechanistically, TMEM97 knockdown caused a reduction of the proliferating marker PCNA and an increase of pro-apoptotic proteins (cleaved caspase 8/3/7 and cleaved PARP) in CRC cells. TMEM97 also positively regulated the β-catenin signaling pathway in CRC cells and xenografts by modulating the phosphorylated-GSK-3β and active (non-phospho) β-catenin levels.

However, up until now, whether LINC01287 is associated with the initiation and development of cervical cancer remains largely unknown. In the present study, expression levels of LINC01287, miR-513a-5p and stress-associated endoplasmic reticulum protein 1 (SERP1) mRNA were quantified utilizing qRT-PCR. A series of functional experiments including CCK-8 assay, colony formation assay, transwell assay, flow cytometry, and tumor xenograft growth of cervical cancer cells were performed for studying the effects of LINC01287. The luciferase reporter assay, pull-down assay, and western blot were used to confirm the downstream targets of LINC01287 and miR-513a-5p. The results demonstrate that LINC01287 was highly expressed in cervical cancer tissue samples and cell lines. High LINC01287 predicts a poor prognosis for cervical cancer patients.

Furthermore, we determined that the impaired Fanconi anemia (FA) pathway contributed to severe DNA damage in AS with chronic lymphedema. We also observed that the activated FANCD2 could facilitate DNMT1 recruitment on genomic DNA. Our study uncovers a novel regulatory mechanism of FA pathway on DNA methylation, and is a benefit to advanced understanding the pathogenesis of AS, as well as providing the potential therapeutic targets for AS treatment.</p>","PeriodicalId":13228,"journal":{"name":"Human Cell","volume":"35 5","pages":"1602-1611"},"PeriodicalIF":4.3,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40494251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
