HOTTIP suppresses ferroptosis via mediating DGCR8/miR‑214‑3p/GPX4 regulatory axis in osteosarcoma. (PubMed, Oncol Rep)
In the present study, HOTTIP was found to be downregulated in the Erastin‑treated OS cells...Mechanically, HOTTIP recruited the RNA binding protein DiGeorge Critical Region 8 (DGCR8) and influenced its protein stability, which disrupted miR‑214‑3p biogenesis and facilitated the de‑repression of glutathione peroxidase 4 transcription, eventually leading to preventing ferroptosis. Taken together, the present study demonstrated that HOTTIP suppressed ferroptosis in OS cells via DGCR8/micro RNA 214‑3p/GPX4 regulatory axis, which might provide insights to develop HOTTIP as a promising therapeutic target for OS patients.
