James Identification of the 16°C compartment of the endoplasmic reticulum in rat liver and cultured hamster kidney cells 2012-02-07 .txt text/plain 3909 196 49 The findings show parallel responses between the temperature dependency of transition vesicle formation in vitro and in situ and suggest that a subpopulation of the transitional endoplasmic reticulum may be morphologically and functionally homologous to the 16°C compartment observed in virally‐infected cell lines grown at low temperatures. Studies were then conducted with isolated transitional endoplasmic reticulum fractions from rat liver to determine if a similar mechanism of control by temperature of transition vesicle formation could be duplicated in the cell-free system. With further increases in temperature, the numbers of transition vesicles appeared to be increased slightly but the tubular elements of the endoplasmic reticulum did not reappear within the Golgi apparatus zone. Numbers of transition vesicles were approximately doubled relative to the control preparations and the peripheral cytoplasm contained numerous tubular transition elements of the endoplasmic reticulum similar in appearance to those observed with incubation at 16°C (Fig. 7A) . ./cache/cord-022774-wasdp2gh.txt ./txt/cord-022774-wasdp2gh.txt
