MicroRNA (miRNA) are a class of non-coding RNA that suppress gene expression by degradation or translational inhibition of target RNA. Several miRNA have been shown to target oncogenes and recently miRNA-125b was shown to translationally and transcriptionally inhibit the p53 gene. Here, we show that an additional isomer of miRNA-125 (miRNA-125a) translationally arrests mRNA of the p53 tumor suppressor...
A novel survival role of focal adhesion kinase (FAK) that involves its nuclear translocation and direct association with p53 has been demonstrated. Here we examined the relationship between the p53/FAK interaction and Ser46 phosphorylation of p53 (p-p53 Ser46 ) in the apoptotic regulation of human esophageal squamous cell carcinoma (HOSCC) cell lines, expressing either wild type (wt) p53 or...
