The most potent stimulation of migration and proliferation of EC and FB was observed at angiogenin concentration of 125 ng/ml in a serum-free medium. Angiogenin had little effect on apoptosis/necrosis of EC and FB. It promoted IL-1β production by EC in a serum-free medium and did not affect FB. Angiogenin had the opposite effects on the production of TNFα and IL-10 by cells: it suppressed the production of these factors by EC in a serum-free medium and enhanced their production by FB in media with and without serum. In a serum-free medium, VEGF production by EC increased and by FB drops. NO production by EC in response to angiogenin stimulation did not depend on the culturing conditions, while NO production by FB increased in complete culture media. Thus, the presence of FCS in the culture medium considerably modulated the effect of angiogenin.</p>","PeriodicalId":9331,"journal":{"name":"Bulletin of Experimental Biology and Medicine","volume":" ","pages":"367-370"},"PeriodicalIF":0.9,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143405877","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}

For reducing metastasis and mortality after resection, the primary tumor should be removed with subcutaneous fat on day 8 after inoculation. Antitumor and antimetastatic effects and reduced mortality were achieved by intraperitoneal injection of carboplatin (63.3 mg/kg) and paclitaxel (13.3 mg/kg); chemotherapy was administered twice.
