Rett syndrome linked to defects in forming the MeCP2/Rbfox/LASR complex in mouse models.

Rett syndrome (RTT) is a severe neurological disorder and a leading cause of intellectual disability in young females. RTT is mainly caused by mutations found in the X-linked gene encoding methyl-CpG binding protein 2 (MeCP2). Despite extensive studies, the molecular mechanism underlying RTT pathogenesis is still poorly understood.

QKI-5 regulates the alternative splicing of cytoskeletal gene ADD3 in lung cancer.

Accumulating evidence indicates that the alternative splicing program undergoes extensive changes during cancer development and progression. The RNA-binding protein QKI-5 is frequently downregulated and exhibits anti-tumor activity in lung cancer. Howeve-r, little is known about the functional targets and regulatory mechanism of QKI-5.

Effects of extraction methods on immunology activity and chemical profiles of Lycium barbarum polysaccharides.

It has been proven that polysaccharides have bioactivities and are beneficial to cure many diseases. Lycium barbarum fruit is widely used as a functional food all over the world, which main active component is L. barbarum polysaccharides (LBPs).

2-O-β-d-glucopyranosyl--ascorbic acid, a novel vitamin C derivative from Lycium barbarum, prevents oxidative stress.

Reducing agents are crucial for the management of maladaptive inflammation-induced macrophage death and hematopoietic toxicity of chemotherapy. 2-O-β-d-glucopyranosyl--ascorbic acid (AA-2βG), a unique AA (or vitamin C) derivative identified in Lycium barbarum, exhibited enhanced free radical scavenging activity compared with AA and its synthetic derivative AA-2αG. AA-2βG protected hydrogen peroxide-induced cell death in murine macrophage RAW264.

Lanostane triterpenes from the mushroom Ganoderma resinaceum and their inhibitory activities against α-glucosidase.

Eighteen previously undescribed lanostane triterpenes and thirty known analogues were obtained from the fruiting bodies of Ganoderma resinaceum. Resinacein C was isolated from a natural source for the first time. The structures of all the above compounds were elucidated by extensive spectroscopic analysis and comparisons of their spectroscopic data with those reported in the literature.
