Tissues were fixed in zinc-formalin, paraffin-embedded, sectioned at 5 µm and stained with hematoxylin and eosin (H&E) or prepared for immunostaining as described (Hao et al. 2018 (link)). Images were captured with 10×, 20×, or 40× objectives using a Nikon Eclipse NI-U with a DS-QI1 or DS-Ri1 camera and NIS Elements software and adjusted in Adobe Photoshop. For IF, antibodies were as follows: rabbit anti-Acss2 (Abcam, 66038), mouse anti-TGIF1 (Santa Cruz Biotechnology, SC-17000), rabbit anti-Acat1 (Proteintech, 16215-1-AP), rabbit anti-Slc2a1 (Millipore 07-1401), and mouse anti-β-catenin (BD Transduction Labs, 610153).
