A preparation of alpha-ecdysone is 100 times less active than ecdysterone. The action of ecdysterone is eliminated when it is removed within 24 h, but after 48 h the inhibiting influence of the hormone becomes irreversible. The diploid line, triploid and tetraploid sublines are sensitive to ecdysterone. The diploid subline with a spontaneously arisen translocation of an X-chromosome to an autosome of the third pair is substantially more resistant to ecdysterone. At 24 h after the addition of ecdysterone, there is a 2-5-fold suppression of the synthesis of total RNA; DNA synthesis is lowered to the same degree only after 48 h. The gross synthesis of proteins, measured according to the incorporation of C 14-lysine, was not suppressed even after 48 h.</p>","PeriodicalId":76730,"journal":{"name":"The Soviet journal of developmental biology","volume":"5 1","pages":"29-36"},"PeriodicalIF":0.0,"publicationDate":"1975-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"11990433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
