Abstract
Glioblastoma multiforme (GBM) is one of the most aggressive forms of brain cancer, characterized by rapid growth and resistance to conventional therapies. This study investigates the role of HADHA, a key enzyme in fatty acid β-oxidation, in the progression of GBM. we show that the overexpression of HADHA in GBM correlates with a poor prognosis in patients and plays a role in promoting tumor growth and invasion. Mechanistically, HADHA regulates the JAK/STAT3 signaling pathway through modulation of H3K27ac histone acetylation. Knockdown of HADHA results in decreased acetyl-CoA levels, leading to reduced H3K27ac modification and subsequent inhibition of JAK/STAT3 activation. Furthermore, we show that the small molecule JIB-04, which targets HADHA, inhibits GBM cell proliferation and invasion both in vitro and in vivo. Our findings highlight the importance of targeting metabolic enzymes in cancer therapy and suggest that HADHA could represent a potential new therapeutic target for GBM. By targeting the metabolic-epigenetic pathway, this strategy presents a promising approach for treating this devastating disorder.
