SMEK1 ablation promotes glucose uptake and improves obesity-related metabolic dysfunction via AMPK signaling pathway.

Obesity has become a major risk of global public health. SMEK1 is also known as a regulatory subunit of protein phosphatase 4 (PP4). Both PP4 and SMEK1 have been clarified in many metabolic functions, including the regulation of hepatic gluconeogenesis and glucose transporter gene expression in yeast.

Arginine methyltransferase PRMT5 negatively regulates cGAS-mediated antiviral immune response.

Cyclic GMP-AMP synthase (cGAS) functions as an essential DNA sensor, which senses the cytoplasmic double-stranded DNA and activates the antiviral response. However, the posttranslational modification of cGAS remains to be fully understood and whether it has arginine methylation modification remains unknown. Here, we identified protein arginine methyltransferase 5 (PRMT5) as a direct binding partner of cGAS, and it catalyzed the arginine symmetrical dimethylation of cGAS at the Arg residue.

A SMOC2 variant inhibits BMP signaling by competitively binding to BMPR1B and causes growth plate defects.

Endochondral ossification is the major process of long bone formation, and chondrogenesis is the final step of this process. Several studies have indicated that bone morphogenetic proteins (BMPs) are required for chondrogenesis and regulate multiple growth plate features. Abnormal BMP pathways lead to growth plate defects, resulting in osteochondrodysplasia.

Isolated Decompression for Transverse Sacral Fractures with Cauda Equina Syndrome.

BACKGROUND The purpose of this study was to evaluate the clinical outcomes of isolated decompression for patients with transverse sacral fractures and cauda equina syndrome, which have been rarely reported before. MATERIAL AND METHODS Twelve neurological impaired patients with transverse sacral fracture from January 2010 to March 2017 treated in our institution were evaluated. All patients went through isolated decompression and were followed for a minimum of 12 months.
