Since HDACs regulate chemokine transcription by both deacetylating histones and p65 NFκB [53,54,55,56,57,58], it will be important to analyze whether βOHB and other HDAC inhibitors regulate chemokine expression in ovarian cancer cells, and whether this is modulated by the metabolic state. The gene discussed is NFKB1; the disease is ovarian carcinoma.
