STAT5A and cervical cancer: To gain further insight into the role of STAT5 in HPV+ cervical cancer, we assessed the relative expression of the two STAT5 isoforms, STAT5A and STAT5B [36] For this, we performed reverse-transcription quantitative PCR (RT-qPCR) and in all the HPV+ cervical cancer cells, STAT5B was expressed at higher levels when compared to HPV- cervical cancer cells (Supplementary Figure S5A).
