Despite the continued use of antibiotics as the primary clinical treatment for diabetic wounds, there is an urgent need to develop antibiotic-free therapeutic strategies to combat MDR bacteria, given the limitations and resistance of antibiotics. In this study, a \"nanotank\", MXene@MOF@CORM-401 (MMC), was designed to target bacteria. The basis of this approach is the combination of 2-dimensional transition metal carbides/carbon nitrides (MXene), metal-organic frameworks (MOFs), and carbon monoxide-releasing molecules (CORMs). MMCs exhibit photothermal and photodynamic properties upon irradiation with near-infrared laser. The photodynamic effect generates a substantial quantity of reactive oxygen species, which subsequently triggers the release of carbon monoxide in a \"gas bombs\"-like manner. In vitro and in vivo experiments have demonstrated that MMC is not only biocompatible but also exhibits robust antimicrobial properties and accelerates diabetic wound healing.

Numerous evidences emerge to support lamin A regulation on cell function and fate by phosphorylation. However, live-cell imaging tools for visualizing the dynamics of pSer22 lamin A are yet to be established. Herein, we developed a novel lamin A phosphorylation sensor (LAPS) based on fluorescence resonance energy transfer (FRET) with high sensitivity and specificity. We observed the dynamic lamin A phosphorylation during the cell cycle progression in single living cells: the increase of pSer22 modification when cells entered the mitosis and recovered upon the mitosis exit. Our biosensor also showed the gradual reduction of pSer22 modification during cell adhesion and in response to hypotonic environment. By applying LAPS, we captured the propagation of pSer22 modification from inside to outside of the inner nuclear membrane, which further led to the breakdown of nuclear envelope. Meanwhile, we found the synchronous phosphorylation of pSer22 lamin A and H3S10ph at mitosis entry. Inhibition of Aurora B, the responsible kinase for H3S10ph, could shorten the mitotic period without obvious effect on the pSer22 modification level of lamin A. Thus, LAPS allows the spatiotemporal visualization of the lamin A pSer22, which will be useful for elucidating the molecular mechanisms underlying cell mitosis and mechanoresponsive processes.</p>","PeriodicalId":93902,"journal":{"name":"Biomaterials research","volume":"28 ","pages":"0091"},"PeriodicalIF":8.1,"publicationDate":"2024-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11494032/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142516811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
