WebT cell reactivity to tumor-specific neoantigens can drive endogenous and therapeutically induced antitumor immunity. However, most tumor-specific neoantigens are unique to each patient (private) and targeting them requires personalized therapy. A smaller subset of neoantigens includes epitopes that span recurrent mutation hotspots, translocations, or … Web15 okt. 2024 · Let-7 negatively targets the expression of a wide range of oncogenes, such as the RAS family, HMGA2 ( 46) and Myc ( 47 ). In addition, Let-7 has been reported to play crucial roles in metastasis by targeting HMGA2 in nasopharyngeal carcinoma ( 42 ), in breast cancer ( 44) and in oral cancer ( 48 ).
