Pimary human keratinocyte knockdown with deltaNp63 specific siRNA

Human ΔNp63-specific siRNA was obtained from Invitrogen (Carlsbad, CA; sense: 5′-ACAAUGCCCAGACUCAAUU-3′; antisense: 5′-AAUUGAGUCUGGGCAUUGU-3′). Scrambled sequence siRNA for the negative control was purchased from Invitrogen. Transfections were performed using Lipofectamine RNAiMAX (Invitrogen) in Opti-MEM (GIBCO) at 40 nmol/L according to the manufacturer's instructions. The culture medium was replaced at 6 h after siRNA transfection. mRNA was extracted from NHEKs transfected with ΔNp63-specific or scramble sequence siRNA at 72 h after transfection. Microarray slides were scanned using a 3D-GENE human 25k (TORAY, Tokyo, Japan) and microarray images were automatically analyzed with AROSTM, version 4.0 (Operon Biotechnologies, Tokyo, Japan). deltaNp63 knockdown keratinocyte vs control siRNA transfected keratinocyte
