The presence of nerve cells does not induce the synthesis of A forms in cultures of 5 day-old myoblasts and does not increase their proportion in cultures of 7 day-old myoblasts. Thus, the capacity to synthesize (or assemble) the complex polymeric forms of AChE does not reflect a direct neural influence but might rather be considered as an intrinsic property of the \"late\" categories of myoblasts that sequentially occur during the differentiation of leg muscles. We studied the synthesis of ChE molecular forms in the mouse muscle C2 cell line. From these experiments we suggest that the synthesis of A forms (or their assembly) can take place as soon as the cells are withdrawn from the cell cycle, but does not require cell fusion by itself. These observations are related to other recent studies that challenge the validity of A forms as topographical/physiological markers of neuromuscular interactions.","PeriodicalId":20966,"journal":{"name":"Reproduction, nutrition, developpement","volume":"28 3B","pages":"693-702"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1051/rnd:19880503","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14316868","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}

Addition of monensin (0.1 microM or 1 microM) to the incubation medium induced a dilatation of Golgi saccules and vesicles and a decrease of the relative volume of microvesicles. Dilated vesicles did not contain acid phosphatase. Neosynthesized proteins were localized by electron microscope autoradiography near the membranes of dilated vesicles. 1 microM monensin did not inhibit basal secretion of neosynthesized caseins (radioactive caseins, labelled during a 3 min pulse, released into the medium), but increased basal secretion of total beta-caseins (measured by radioimmunoassay). Monensin abolished all the effects of prolactin (increase in the relative volume of Golgi microvesicles and stimulation of secretion of total and neosynthesized caseins). These results show that monensin provokes simultaneously modifications in the Golgi apparatus morphology and inhibition of the prolactin stimulating effect. Moreover, secretion of intracellular caseins is differently modified, depending probably on whether caseins are neosynthesized or stored.","PeriodicalId":20966,"journal":{"name":"Reproduction, nutrition, developpement","volume":"28 2A","pages":"303-17"},"PeriodicalIF":0.0,"publicationDate":"1988-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14502708","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}
