Suppression of ethanolamine-containing glycerophospholipid synthesis in HL-60 cells during retinoic acid-induced differentiation.

abstract：:Using the mRNA differential display technique and Western blot analysis, the present study demonstrates that induction of KAR2 occurs when misfolded membrane-bound cytochrome P450, mutated in its cytosolically exposed domain, is expressed in Saccharomyces cerevisiae. Using various KAR2 promoter constructs in front of ...
