Validation of transcriptomics data. cDNAs derived from unlesioned, lesioned, lesioned and SRF-ΔMADS-VP16-positive and lesioned and SRF-VP16-positive facial nuclei were subjected to qPCR analysis with the indicated primers. Every bar reflects mRNA levels obtained from a cDNA sample in which facial nuclei of four independent animals were pooled. Numbers of independent cDNAs are indicated at bars. Statistical significance was calculated in relation to control (no lesion/no virus).
