In some embodiments, the methods comprise contacting a tumor cell or tumor with a GCS inhibitor. In some embodiments, the tumor cell or tumor has elevated expression of serine hydroxymethyltransferase 2 (SH1VIT2). In some aspects, methods of identifying a tumor cell or tumor that is sensitive to inhibiting the GCS are provided, the methods comprising determining whether the tumor cell or tumor overexpresses SHMT2.
