Fig. 2From: TNF up-regulates Pentraxin3 expression in human airway smooth muscle cells via JNK and ERK1/2 MAPK pathwaysTNF-induced PTX3 promoter activity in HASMC. HASMC were transiently transfected with the PTX3 promoter luciferase construct and stimulated with 10 ng/ml of TNF or vehicle for 12 h. Values are presented as the mean fold increase of luciferase activity normalized to the mock renilla luciferase activity from 5 different HASMC (**P < 0.01)Back to article page
