Next, we decided to determine the expression of all IL-6 family receptors including Interleukin-6 receptor (IL-6R), Interleukin-11 receptor (IL-11RA), IL-31RA, leukemia inhibitory factor receptor (LIFR), OSMR and its subunit IL6ST, ciliary neurotrophic factor receptor (CNTFR), that are widely known for their oncogenic actions23 in both sensitive and cisplatin-resistant ovarian cancer cells by qPCR (Fig. 1e). The gene discussed is CNTFR; the disease is ovarian carcinoma.
