Abstract The progestin regimen is one of the main therapeutic strategies for women with endometrial cancer who undergo conservative management. Although many patients respond well to initial therapy, progestin‐refractory disease inevitably emerges, and the molecular basis underlying progestin resistance has not been comprehensively elucidated. Herein, they demonstrated progestin results in p38‐dependent IDH1 Thr 77 phosphorylation (pT77‐IDH1). pT77‐IDH1 translocates into the nucleus and is recruited to chromatin through its interaction with OCT6. IDH1‐produced α‐ketoglutarate (αKG) then facilitates the activity of OCT6 to promote focal adhesion related target gene transcription to confer progestin resistance. Pharmacological inhibition of p38 or focal adhesion signaling sensitizes endometrial cancer cells to progestin in vivo. The study reveals p38‐dependent pT77‐IDH1 as a key mediator of progestin resistance and a promising target for improving the efficacy of progestin therapy. |
