Apoptotic index of NPC cells $(\overline{\mathsf{\text{X}}}\pm \mathsf{\text{s)}}$

Samples	Apoptotic index	F	P
pEGFP-C3-PinX1	49.733 ± 2.702*	183.419	0.000
pEGFP-C3	19.566 ± 0.577
Lipofectamine alone	19.066 ± 0.665
Untreated	19.266 ± 0.763
PinX1-FAM-siRNA	17.166 ± 2.663**

* vs untreated, P < 0.001; ** vs untreated, P > 0.05.

Apoptotic Index = apoptotic cell number/total cell number × 100%.
