The first step in repair, the association of pieces of endoplasmic reticulum with holes in the nuclear membranes, appears to be a passive process since it was not affected by inhibitors of energy production, RNA synthesis, or protein synthesis. In contrast, fusion of pieces of endoplasmic reticulum with the nuclear membranes at the margins of the holes was blocked by KCN and dinitrophenol, indicating that membrane fusion requires energy derived from respiration, but RNA and protein synthesis inhibitors did not prevent fusion of pieces of endoplasmic reticulum with the nuclear membranes. The subsequent completion of repair and restoration of intact nuclear membranes was almost completely blocked by inhibitors of respiration, and it was reduced in the presence of actinomycin and emetine, suggesting that in addition to a requirement for energy, some later steps in the repair of the nuclear membranes require RNA and protein synthesis.<\/jats:p>","DOI":"10.1242\/jcs.21.2.291","type":"journal-article","created":{"date-parts":[[2021,4,24]],"date-time":"2021-04-24T05:17:04Z","timestamp":1619241424000},"page":"291-302","source":"Crossref","is-referenced-by-count":1,"title":["Metabolic requirements for interactions between nuclear and cytoplasmic membranes in the repair of damaged amoeba nuclei"],"prefix":"10.1242","volume":"21","author":[{"given":"Charles J.","family":"Flickinger","sequence":"first","affiliation":[{"name":"University of Virginia Department of Anatomy, School of Medicine , , Charlottesville, Virginia 22901, U.S.A."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"237","published-online":{"date-parts":[[1976,7,1]]},"reference":[{"key":"2023062015455301700_JOCES_21_2_291C1","doi-asserted-by":"crossref","first-page":"125","DOI":"10.1016\/B978-0-12-384850-5.50011-7","article-title":"Ultrastructure","volume-title":"In The Biology of Amoeba","author":"Daniels","year":"1973"},{"key":"2023062015455301700_JOCES_21_2_291C2","first-page":"273","article-title":"Structure and function of the nuclear envelope","volume":"2","author":"Feldherr","year":"1972","journal-title":"Adv. cell, molec.
