TFE3 activation in a TSC1-altered malignant PEComa: challenging the dichotomy of the underlying pathogenic mechanisms [PDF]

, 2020
Perivascular epithelioid cell tumors (PEComas) form a family of rare mesenchymal neoplasms that typically display myomelanocytic differentiation. Upregulation of mTOR signaling due the inactivation of TSC1/2 (Tuberous Sclerosis 1 and 2) is believed to be

Decoding the Hexosamine Biosynthesis Pathway: Implications for Novel Therapeutic Strategies in Sarcoma

Journal of Cellular Physiology, Volume 241, Issue 5, May 2026.
ABSTRACT Cancer cells rewire their metabolism to sustain a high proliferation rate. Sensing external cues is essential to match the metabolic fluxes of the cells to the external stimuli. As part of the glucose metabolism, the hexosamine biosynthesis pathway (HBP) is considered a nutrient‐sensing pathway. The HBP produces UDP‐GlcNAc, a key precursor for
