GNG7 and cancer: Among 1037 detected proteins, a membrane-localized patatin-like phospholipase AII-1 (SbpPLAII-1) attracted our attention (Supplementary Fig. 9a, b and Supplementary Data 7) since previous studies showed Gγ subunit 7 (GNG7) can inhibit cell proliferation in human Hela and U2OS cells20, while human group VIA phospholipase A2 (iPLA2) generally promotes proliferation of cancer cells21–23.
