Targeting of TRX2 by miR-330-3p in melanoma inhibits proliferation.
This study is intended to identify the key gene from gene expression profile and validate its role and regulatory mechanism in melanoma. ⋯ Inhibiting TPX2 by miR-330-3p suppresses the proliferation of melanoma cell lines. miR-330-3p/TPX2 pathway could be a potential therapeutic target in melanoma.

Effects of miR-26a-5p on neuropathic pain development by targeting MAPK6 in in CCI rat models.
MicroRNA are emerging as significant regulators of neuropathic pain progression. In addition, neuroinflammation contributes a lot to neuropathic pain. miR-26a-5p has been identified as an inflammation-associated miRNA in multiple pathological processes. However, little is known about the biological role of miR-26a-5p in neuroinflammation and neuropathic pain development. ⋯ Meanwhile, MAPK6 expression and miR-26a-5p were oppositely correlated in CCI rats. Furthermore, up-regulation of MAPK6 obviously reversed the suppressive effect of miR-26a-5p on neuroinflammation and neuropathic pain progression. Taken these together, our results implied that miR-26a-5p could act as a negative regulator of neuropathic pain development through targeting MAPK6, which indicated that miR-26a-5p might serve as a potential therapeutic target for neuropathic pain.

MicroRNA-92a antagonism attenuates lipopolysaccharide (LPS)-induced pulmonary inflammation and injury in mice through suppressing the PTEN/AKT/NF-κB signaling pathway.
Overwhelming lung inflammation is a key feature of acute lung injury (ALI). MicroRNAs (miRNAs) have been implicated in the regulation diverse cellular processes including the inflammatory response. However, little is known about their functions and molecular involvement in regulating the inflammatory process in ALI. ⋯ In addition, we identified that miR-92a inhibited the phosphatase and tensin homolog on chromosome ten (PTEN) by binding to its 3'-UTR in RAW264.7 murine macrophage cells. Western blot analysis demonstrated that inhibition of miR-92a may ameliorate inflammatory response through blocking PTEN/AKT/NF-κB signaling pathway in ALI mice. Collectively, these results have revealed a significant role of miR-92a in the lung inflammatory response associated with ALI in mice, and suggest that miR-92a may have potential as a prognostic indicator and novel therapeutic target for the treatment of ALI in future.
