Knockdown of LANP by RNA interference. A, PC12 cells
transfected with a pool of siRNA targeting LANP show reduced expression at the
protein level as demonstrated by Western blot (WB). As expected, no
reduction of LANP is found with control siRNA or cells transfected in a mock
manner (no siRNA). Western blot performed with an anti-actin antibody serves
as a loading control. B, PC12 cells transfected with siRNA targeting
LANP show reduced expression at the RNA level as demonstrated by RT-PCR. Once
again, no reduction of LANP is found with control siRNA or cells transfected
in a mock manner (no siRNA). In these experiments, the GAPDH message was
measured as an internal control. C, quantitative RT-PCR comparing
PC12 cells transfected with LANP siRNA and control (C) siRNA. Ct
(threshold cycle) value of each sample is normalized to GAPDH and -fold change
is relative to control transfected PC12 cells. *, p <
0.0001.
