Here, we used a HeLa cell line, inducibly expressing a GFP fusion protein [GFP-b(5)tail] anchored to the ER membrane, as a tool to investigate factors influencing ER organisation. Induction of GFP-b(5) tail expression caused proliferation of the ER, but its normal branching polygonal meshwork architecture was maintained. Experiments designed to test the effects of drugs that alter ceramide levels revealed that treatment of these cells with Phenyl-2-decanoyl-amino-3-morpholino-1-propanol-hydrocholride (PDMP) generated patches of segregated smooth ER, organised as a random tubular network, which rapidly dispersed after removal of the drug. The effect of PDMP was independent of its activity as sphingolipid synthesis inhibitor, but could be partially reversed by a membrane-permeant Ca2+ chelator. Although the smooth ER patches maintained connectivity with the remaining ER, they appeared to represent distinct domains differing in protein and lipid composition from the remaining ER. PDMP did not cause detachment of membrane-bound ribosomes, indicating that smooth ER patch generation was due to a reorganisation of preexisting ribosome-free areas. Our results demonstrate a dynamic relationship between smooth and rough ER and have implications for the mechanisms regulating ER architecture."@en ; prodottidellaricerca:prodottoDi modulo:ID2648 , istituto:CDS061 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA19267 , unitaDiPersonaleEsterno:ID1833 , unitaDiPersonaleEsterno:ID2100 . @prefix parolechiave: . prodotto:ID37824 parolechiave:insiemeDiParoleChiave . ns12:ID394912 pubblicazioni:rivistaDi prodotto:ID37824 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID37824 .
