A-E:. MOLM-14 cells were treated with CNL 15μM,
Ara-C 1.25μM, venetoclax 50nM alone or in combinations as indicated for
24 hours, prior to lipid analyses. Shown are total ceramide levels
(A), individual ceramide species (A-C), ratios of
the change in long-chain C16- to very-long-chain C24:1-ceramide
(D), and levels of sphingosine and sphingosine-1-phosphate (E). N=
4–5, shown are means +/− S.E.M. * p < 0.02 to Vehicle; #
p<0.001 to CNL/Ara-C/venetoclax (A); ^, p<0.005 to
vehicle (E).
