Alteration of autophagy in FLV- and FLV-SNED-treated
cells: Relative
expression of autophagy-related LC3B mRNA in MCF-7 cells at indicated
time points after treatment with DMSO, SNED, FLV, or FLV-SNED (10
μM). *P < 0.05 FLV vs DMSO at 16 and 24
h, **P < 0.01 FLV-SNED vs SNED at 16 and 24 h.
Two experiments performed in duplicate (A). MCF-7 cells were treated
with FLV, FLV-SNED, or DMSO and were incubated with or without chloroquine
(CQ, 25 μM). Lysates were immunoblotted with anti-LC3 antibody.
Representative immunoblot of LC3 proteins, LC31 (18 kDa) and LC3II
(16 kDa). Actin served as loading control (B). Densitometric quantification
of LC3II. ****P < 0.0001 FLV + CQ vs DMSO + CQ,
**P < 0.01 FLV vs FLV-SNED, *P < 0.05 FLV-SNED + CQ vs FLV + CQ. Four experiments performed
in duplicate (C).
