KRAS and urinary bladder carcinoma: Analysis of human pancreatic adenocarcinoma-derived MIA PaCa-2 cells with KRAS G12C mutation, human bladder carcinoma-derived T24 cells with HRas G12V, and exogenous KRAS G12V-expressing NIH3T3 cells revealed that these cells obtain glutamine needed for proliferation by uptake of albumin from the extracellular fluid via macropinocytosis [135].
