WebAug 12, 2024 · The Harvey rat sarcoma viral oncogene homolog (Hras) can be expressed upstream of miRNA instead of serving as a target of miRNA. Hras in mouse keratinocytes represses miR-203, which is the most upregulated gene during keratinocyte differentiation [ 37 ], leading to cell proliferation [ 86 ]. WebH-Ras, a member of the Ras family of GTPases, was originally identified as the transforming protein encoded by the Harvey rat sarcoma retrovirus ( 1 ). Activating mutations in H-Ras and its family members, K-Ras and N-Ras, were identified in a variety of cancers, and nearly 30% of all cancers have mutations in one of the Ras genes ( 2, 3 ).
