ANGPTL6 and cervical cancer: We first generated and characterized multiple, stable neomycin-resistant MDA-MB-468 HBC and HeLa cervical cancer sublines that express catalytically-inactive MAPK/SAPK isoforms (ERK1 AEF; JNK1a1 APF; JNK2a2 APF; p38δ AGF; p38γ APF; and p38γ AGF) as described in methods (Supplementary Figures S3A-C, F, G, K, L).
