Akt kinase is activated by transforming growth factor-beta1 (TGF-beta) in diabetic kidneys, and has important roles in fibrosis, hypertrophy and cell survival in glomerular mesangial cells. However, the mechanisms of Akt activation by TGF-beta are not fully understood. Here we show that TGF-beta activates Akt in glomerular mesangial cells by inducing the microRNAs (miRNAs) miR-216a and miR-217, both of which target PTEN (phosphatase and tensin homologue), an inhibitor of Akt activation. These miRNAs are located within the second intron of a non-coding RNA (RP23-298H6.1-001). The RP23 promoter was activated by TGF-beta and miR-192 through E-box-regulated mechanisms, as shown previously. Akt activation by these miRs led to glomerular mesangial cell survival and hypertrophy, which were similar to the effects of activation by TGF-beta. These studies reveal a mechanism of Akt activation through PTEN downregulation by two miRs, which are regulated by upstream miR-192 and TGF-beta. Due to the diversity of PTEN function, this miR-amplifying circuit may have key roles, not only in kidney disorders, but also in other diseases.

MicroRNAs (miRNAs) are integral elements in the post-transcriptional control of gene expression. After the identification of hundreds of miRNAs, the challenge is now to understand their specific biological function. Signalling pathways are ideal candidates for miRNA-mediated regulation owing to the sharp dose-sensitive nature of their effects. Indeed, emerging evidence suggests that miRNAs affect the responsiveness of cells to signalling molecules such as transforming growth factor-beta, WNT, Notch and epidermal growth factor. As such, miRNAs serve as nodes of signalling networks that ensure homeostasis and regulate cancer, metastasis, fibrosis and stem cell biology.

Tumor recurrence and metastases are the major obstacles to improving the prognosis of patients with hepatocellular carcinoma (HCC). To identify novel risk factors associated with HCC recurrence and metastases, we have established a panel of recurrence-associated microRNAs by comparing the microRNA expression in recurrent and non-recurrent human HCC tissue samples using microarrays (recurrence is defined as recurrent disease occurring within a 2-year time point of the original treatment). Among the panel, expression of the miR-216a/217 cluster was consistently and significantly upregulated in HCC tissue samples and cell lines associated with early tumor recurrence, poor disease-free survival and an epithelial-mesenchymal transition (EMT) phenotype. Stable over-expression of miR-216a/217-induced EMT, increased the stemlike cell population, migration and metastatic ability of epithelial HCC cells. PTEN and SMAD7 were subsequently identified as two functional targets of miR-216a/217, and both PTEN and SMAD7 were downregulated in HCC. Ectopic expression of PTEN or SMAD7 partially rescued miR-216a/217-mediated EMT, cell migration and stem-like properties of HCC cells. Previously, SMAD7 was shown to be a TGF-beta type 1 receptor antagonist. Here, we further demonstrated that the overexpression of miR-216a/217 acted as a positive feedback regulator for the TGF-beta pathway and the canonical pathway involved in the activation of PI3K/Akt signaling in HCC cells. Additionally, activation of the TGF-beta and PI3K/Akt signaling pathways in HCC cells resulted in an acquired resistance to sorafenib, while blocking the activation of TGF-beta pathway overcame miR-216a/217-induced sorafenib resistance and prevented tumor metastases in HCC. Conclusion: our present study demonstrates that overexpression of miR-216a/217 activates the PI3K/Akt and TGF-beta pathways by targeting PTEN and SMAD7, contributing to hepatocarcinogenesis and tumor recurrence in HCC.
