GLTP knockdown by RNAi does not alter cell phenotype.

A) HeLa cells transfected with empty vector (control) or RNAi to GLTP mRNA (pSuper.puro-egfp-214) were analyzed by Western blot using β-actin expression as positive control. B) Epifluorescence microscopy showed that HeLa cell shape was not altered when GLTP expression was knocked down by siRNA.
