YTHDF2 upregulates the m6A level in the 5′‐untranslated region of OCT4 mRNA to elevate the translation and expression of OCT4.[14] Thus, we next assessed whether OCT4 mediates the HSP90β/STUB1‐regulated cell proliferation in HCC. The gene discussed is HSP90AB1; the disease is hepatocellular carcinoma.
