Expression profiles analysis identifies a novel three-mRNA signature to predict overall survival in oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) remains to be a challenging public health problem worldwide. However, the underlying molecular mechanism regulating the carcinogenesis of OSCC is poorly known. Gene expression profiles of GSE13601, GSE30784, GSE37991 and The Cancer Genome Atlas (TCGA) head and neck cancer were downloaded from gene expression omnibus (GEO) and TCGA database respectively.

Astragalus polysaccharides attenuates TNF-α-induced insulin resistance via suppression of miR-721 and activation of PPAR-γ and PI3K/AKT in 3T3-L1 adipocytes.

Insulin resistance is associated with obesity and type 2 diabetes. The aim of this study was to explore the mechanism of how Astragalus Polysaccharides (APS) improves insulin resistance in 3T3-L1 adipocytes. A cell culture model of insulin resistance was established in mature 3T3-L1 adipocytes by treating them with TNF-α, high glucose and insulin.
