Fig. 3From: HPV 16 E7 alters translesion synthesis signalingExogenous nucleoside supplementation decreases replication stress and TLS activation in cervical cancer cell lines. Representative immunoblots of cervical cancer cell lines (HeLa and SiHa) probed for A a marker of replication stress (p-ATR) and TLS pathway activation (ub-PCNA) along with total levels of each of these proteins and B representative TLS proteins. Whether the cell lines were grown in media supplemented with exogenous nucleosides is indicated below the immunoblot image with “ + ” indicating nucleosides were added and “−“ indicating that they were not. GAPDH and Nucleolin were used as loading controlsBack to article page
