Hepatocellular carcinoma (HCC) accounts for a large proportion of cancer-associated mortality worldwide. The functional impact of long noncoding RNAs (lncRNAs) in human cancer is not fully understood. Here, we identified a novel oncogenic lncRNA termed lncPARP1, which was significantly upregulated in HCC. Increase of lncPARP1 expression was associated with age, AFP levels, tumor size, recurrence, and poor prognosis of HCC patients. Loss-of-function approaches showed that knockdown of lncPARP1 inhibited proliferation, migration and invasion, while induced apoptosis in HCC cells...

Aspergillus cristatus belongs to the homothallic fungal group that undergoes a sexual stage without asexual conidiation under hypotonic conditions, while hypertonic medium induces initiation of the asexual stage and completely blocks sexual development. However, the veA deletion mutant only produces conidia in hypotonic medium after a 24 h culture, but both asexual and sexual spores are observed after 72 h. To elucidate the molecular mechanism of how VeA regulates asexual and sexual spore development in A. cristatus , two dimensional electrophoresis combined with matrix-assisted laser desorption/ionization-tandem time of flight mass spectrometry analysis were applied to identify 173 differentially expressed proteins (DEPs) by comparing the agamotype (24 h) and teleomorph (72 h) with wild-type A...

We introduced polyethyleneimine-cholesterol (PC) as a nanocarrier incorporating berberine (BER) and miRNA122 (miR-122) for the treatment of oral squamous cell carcinoma. BER was stabilized by incorporating PC to form ber -PC. Ber -PC was further electrostatically complexed with miR-122 to yield mr-ber- PC for the co-delivery of BER and miR-122. mr-ber- PC treatment dramatically decreased the level of invasion and migration of oral squamous cell carcinoma cells compared with single drug treatments. This study suggested that PC could be a multifunctional nanocarrier for the co-delivery of anti-cancer drug BER and miR-122 to significantly increase the anti-cancer therapeutic effects...
