Precise let-7 expression levels balance organ regeneration against tumor suppression
The in vivo roles for even the most intensely studied microRNAs remain poorly defined. Here, analysis of mouse models revealed that let-7, a large and ancient microRNA family, performs tumor suppressive roles at the expense of regeneration. Too little or too much let-7 resulted in compromised protection against cancer or tissue damage, respectively. Modest let-7 overexpression abrogated MYC-dri...
متن کاملTumor and Stem Cell Biology LIN28 Expression in Malignant Germ Cell Tumors Downregulates let-7 and Increases Oncogene Levels
Despite their clinicopathologic heterogeneity, malignant germ cell tumors (GCT) share molecular abnormalities that are likely to be functionally important. In this study, we investigated the potential significance of downregulation of the let-7 family of tumor suppressor microRNAs in malignant GCTs. Microarray results from pediatric and adult samples (n1⁄4 45) showed that LIN28, the negative re...
متن کاملLet-7-mediated suppression of mucin 1 expression in the mouse uterus during embryo implantation
Mucin 1 (Muc1) is an integral transmembrane mucin glycoprotein expressed on the apical surface of most epithelia. It is considered to be a barrier to the regulation of embryo implantation by inhibiting attachment of the embryo to the endometrium. Therefore, loss of Muc1 on the surface of uterine epithelial cells is necessary for embryo implantation. Studies have demonstrated that microRNAs (miR...

متن کاملDICER1 regulated let-7 expression levels in p53-induced cancer repression requires cyclin D1
Let-7 miRNAs act as tumour suppressors by directly binding to the 3'UTRs of downstream gene products. The regulatory role of let-7 in downstream gene expression has gained much interest in the cancer research community, as it controls multiple biological functions and determines cell fates. For example, one target of the let-7 family is cyclin D1, which promotes G0/S cell cycle progression and ...
