Fig. 3From: HPV-mediated down-regulation of NOD1 inhibits apoptosis in cervical cancerExpression of NOD1 in 3 cervical squamous carcinoma cells was detected by immunocytochemistry (a), quantitative real-time PCR (b) and Western blot (c). NOD1 showed strongest expression in the HPV (−) C33A cells and was weakest in the HPV16 (+) SiHa cells. *P < 0.05, ****P < 0.0001Back to article page
