AKT1 and breast carcinoma: Accordingly, another group has demonstrated that miR-302 family is able to sensitize breast cancer cells to radiotherapy; in particular Liang et al. showed that the decreased expression of miR-302a induces radiotherapy resistance and the reintroduction of miR-302a expression enhances radiotherapy sensitivity in in vitro and in vivo breast cancer models, abrogating the expression of AKT1 and RAD52 (78).
