SACK1G and cancer: We observed that PAWS1 protein expression was absent in many human cancer cells, including SK‐ES (bone), MCF‐7 (breast), SK‐N‐MC (brain), and PC3 (prostate) cells while robust expression was observed in HCT116 (colorectal), HEPG2 (liver), PNTA1 (prostate) and HeLa (cervical) cells.
