Editing the cystine knot motif of MSTN enhances muscle development of Liang Guang Small Spotted pigs.

Myostatin (MSTN) is a member of the transforming growth factor-β (TGF-β) family, and functions as an inhibitor of muscle growth. Disrupting the inhibitory effect of MSTN on growth can provide an effective way to increase the muscle yield of livestock and poultry. The cysteine knot motif of TGF-β can stabilize the structure of MSTN protein and plays an important regulatory role in the biological function of MSTN.

Magnetic resonance imaging-three-dimensional printing technology fabricates customized scaffolds for brain tissue engineering.

Conventional fabrication methods lack the ability to control both macro- and micro-structures of generated scaffolds. Three-dimensional printing is a solid free-form fabrication method that provides novel ways to create customized scaffolds with high precision and accuracy. In this study, an electrically controlled cortical impactor was used to induce randomized brain tissue defects.

Curcumin attenuates ischemia-like injury induced IL-1β elevation in brain microvascular endothelial cells via inhibiting MAPK pathways and nuclear factor-κB activation.

Inflammatory reactions play a key role in the cerebral injury after stroke or other ischemic brain diseases. Curcumin, which is extracted from herb turmeric, has been reported to have anti-inflammatory effects. The present study was aimed to investigate the anti-inflammatory effects of curcumin on oxygen-glucose deprivation (OGD) injured brain microvascular endothelial cells (BMECs).
