PIP3 levels in salivary glands.
(A) Mutant and wild-type dPIP4K rescue.
(B) Control, mutant, and kinase-dead dPIP4K rescue.
(C) (i) Immunoblot (from wandering third instar larvae) showing salivary
gland-specific depletion of dPIP4K (dPIP4KRNAi).
(ii) PIP3 levels in control and
dPIP4KRNAi salivary glands.
(D) (i) Immunoblot for dPIP4K knockdown in S2R+ cells with two
different dsRNAs. (ii) Total PIP3 using LCMS in whole cell lipid
extracts of S2R+ cells treated with indicated dsRNAs (data pooled
from two experiments, a total of four biological replicates). Scatter plots with
mean ± SD. Statistical test: one-way ANOVA with post hoc Tukey’s
multiple pairwise comparison. *p value < 0.05; **p value
<0.01.
(E) Western blots for (i) pAKTT342 and (ii) pS6KT398 levels
in control and dPIP4K knockdown cells.
