However, the mechanisms responsible for the oncogenic properties of mycoplasmas remain poorly understood. We have developed an infectious model of LNCaP prostate lymph node carcinoma cell line infection with Mycoplasma hominis (MHO). It has been shown that MHO can easily attach and invade into cells without reducing the growth rate or affecting morphology of LNCaP cells. Proteomic analysis has shown that during infection, MHO undergoes a significant functional restructuring decelerating its growth and leading to formation of mini colonies. This reorganization is associated with a shift in energy metabolism a less energy-efficient nucleoside utilization pathway. To adapt within LNCaP, MHO changes its repertoire of membrane proteins, variable antigens involved in adhesion and protection from host immunity. It is hypothesized that the transcription factor YebC plays a role in MHO survival within the eukaryotic cell.</p>","PeriodicalId":9331,"journal":{"name":"Bulletin of Experimental Biology and Medicine","volume":"178 5","pages":"637-642"},"PeriodicalIF":0.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143989827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sham-operated animals were used as a control. In both groups, a distinct response of the CPM vessels of different branching orders to vasodilators was observed: in pharmacological tests (acetylcholine, nitroglycerin), a dependence of the ED or EI vascular reactivity on the diameter of the arteries was found.
