These intrinsic events within tumor cells enhance ER stress‐associated ubiquitylation and degradation by triggering ubiquitin via the E1 activase UBA6, facilitating ubiquitin transferring to E2 conjugate UBE2Z and increasing the activities of E3 ligase FBXW7 to degrade both EZH2 and MYC. This evidence concerns the gene MYC and neoplasm.
