IHC was performed as previously described69 (link) using a 1:400 antibody dilution for PKM2 (C-11), 1:600 dilution for PKM1 (Cat# NBP2-14833, Novus Biologicals; Littleton, CO), and 1:250 dilution for GLUT1 (AbCam; Cat# ab652). ISH was performed as described70 (link) using LNA microRNA ISH miR-122 optimization kit (Cat# 90003, Exiqon; Woburn, MA) followed by incubation of sheep anti-digoxigenin-AP (Cat# 11093274910, Roche Diagnostics; Mannheim, Germany), and developed with NBT:BCIP (Cat# SK-5400, Vector Laboratories; Burlingame, CA) at 30°C overnight. Nuclear fast red was used to counterstain nuclei (Cat# H-3403, Vector Laboratories).
