CAF-derived IL-6 decreased HIC1 expression in SK-BR-3 cells. HIC1 was decreased in SK-BR-3 cells cocultured with CAF40 and CAF74 compared to cells cocultured with NAF1. b-c HIC1 was decreased in SK-BR-3 by rhIL-6 in a time- and dose-dependent manner. d The decreased HIC1 induced by rhIL-6 was completely restored by STAT3 inhibition
