TRIM47 promotes head and neck squamous cell carcinoma malignant progression by degrading XAF1 through ubiquitination.

Tripartite motif-containing 47 (TRIM47) is a member of the TRIM family, which has E3 ligase activity and has been demonstrated to be involved in tumor development. In this work, we found that TRIM47 is highly expressed in head and neck squamous cell carcinomas (HNSCC) tissues. TRIM47 overexpression promoted HNSCC cell proliferation.

Effects of metformin on bone mineral density and bone turnover markers: a systematic review and meta-analysis.

Objectives: Metformin is associated with osteoblastogenesis and osteoclastogenesis. This study aims to investigate the impacts of metformin therapy on bone mineral density (BMD) and bone turnover markers.

Design: Systematic review and meta-analysis of randomised controlled trials.

Radical cascade reaction of alkynes with N-fluoroarylsulfonimides and alcohols.

Cascade reactions initiated by radical addition to alkynes are synthetically very attractive because they enable access to highly complex molecular skeletons in only few synthetic steps under usually mild conditions. Here we report a general radical cascade reaction of alkynes, N-fluoroarylsulfonimides and alcohols, enabling the efficient synthesis of important α-amino-α-aryl ketones from readily available starting materials via a single operation. During this process, the highly regioselective nitrogen-centred radical addition to internal and terminal alkynes generating vinyl radicals and the next explicit migration of aryl group from the nitrogen source lead the following efficient desulfonylation, oxygenation, and semi-pinacol rearrangement.
