Fig. 2From: Palmitate induces cisternal ER expansion via the activation of XBP-1/CCTα-mediated phospholipid accumulation in RAW 264.7 cellsPalmitate induces cisternal ER expansion in RAW 264.7 cells. Cells were treated with palmitate at the indicated concentration for 24 h (a) and with 400 μM palmitate for the indicated times (b). Changes in ER structure were examined by transmission electron microscopy (a and b). Immunogold staining of calnexin was performed on ultrathin sections of cryoprocessed RAW 264.7 cells (c)Back to article page
