droplet (LD) biogenesis induced by stress. Cytotoxic inhibitors of fatty acid synthase induced
TAG synthesis and LD biogenesis in CHO-K1 cells, in the absence of external sources of
fatty acids. TAG synthesis was required for LD biogenesis and was sensitive to inhibition
and down-regulation of the expression of group VIA phospholipase A 2 (iPLA 2-VIA).
Induction of stress with acidic pH, C 2-ceramide, tunicamycin, or deprivation of glucose also …
