In this study, we investigated the effects of interface stiffness on gene expression pathways by hydrogels with divergent stiffness. Our results reveal that adhesive interface stiffness affects cytoplasmic mechanotranduction as well as nuclear mechanics, and ultimately regulating the subcellular localization of HDAC3. Further investigation unfolds that HDAC3 directly affects global acetylation levels within nucleus. And HDAC3-induced acetylation changes are regulated by myosin contraction, thereby portraying downstream gene expression. Additionally, our study indicates that the interface stiffness-mediated regulation of HDAC3 nuclear-cytoplasmic redistribution is dependent on CRM1, and inhibition of CRM1 impedes the nuclear export of HDAC3. In summary, our work provides an overview of how the subcellular localization of HDAC3 can be manipulated through the regulation of cell adhesion interface stiffness, thereby altering upstream RNA polymerase II activity and gene expression.</div>","PeriodicalId":10483,"journal":{"name":"Colloid and Interface Science Communications","volume":null,"pages":null},"PeriodicalIF":4.5,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49707743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zirconium improves the chemistry and morphology of materials for fluoride adsorption.

The formation of biofilms leading to infections has a significant global impact, afflicting millions of patients and resulting in an approximate 1.6 million fatalities each year. Furthermore, the economic ramifications of such infections are considerable, with industries incurring billions of dollars in costs on an annual basis. Given that bacteria tend to proliferate in a community-based and surface-bound fashion, many studies have recently focused on the development of coatings that inhibit bacterial adhesion. Earlier designs were primarily monofunctional and relied on either antibacterial effect that inactivates bacteria; antifouling effect that repels bacteria; or anticontact effect that restricts the wetting of planktonic bacteria. However, these strategies can individually suffer from some drawbacks that restrict their broader utility. To advance the state-of-art of coatings against bacterial contamination and fouling, emerging trends have focused on synergistic combination of antibacterial, antifouling, and anticontact effect in the form of multifunctional coatings or interfacial materials.
