NR5A1 and cervical carcinoma: In parallel, Western blot analyses of infected HeLa cervical carcinoma cells using an antiserum specific for bovine NR5A1 [46] were performed, demonstrating the expression of a major protein band with an estimated molecular weight of approximately 52 kDa comigrating with bovine NR5A1 protein in vitro translated from the original plasmid expression vector (Fig. 1C).
