CD90 Promotes Gastric Cancer Progression by Regulating SLC1A5‐Mediated Glutamine Metabolism Through YY1

open access: yesCancer Science, EarlyView.
The CD90‐YY1‐SLC1A5 axis plays a significant role in gastric cancer. CD90 promotes the binding of YY1 to the SLC1A5 promoter. CD90 regulates SLC1A5‐mediated glutamine metabolism and ferroptosis. ABSTRACT CD90 (THY1) is a cell surface glycoprotein that plays a crucial role in the occurrence and development of various malignant tumors.
