Protective effect of centipedegrass against Aβ oligomerization and Aβ-mediated cell death in PC12 cells.

Context: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the abnormal accumulation of β-amyloid (Aβ). Multiple Aβ-aggregated species have been identified, and neurotoxicity appears to be correlated with the amount of non-fibrillar oligomers. Potent inhibitors of Aβ oligomer formation or Aβ-induced cell toxicity have emerged as attractive means of therapeutic intervention.

Coprinus comatus cap inhibits adipocyte differentiation via regulation of PPARγ and Akt signaling pathway.

This study assessed the effects of Coprinus comatus cap (CCC) on adipogenesis in 3T3-L1 adipocytes and the effects of CCC on the development of diet-induced obesity in rats. Here, we showed that the CCC has an inhibitory effect on the adipocyte differentiation of 3T3-L1 cells, resulting in a significant decrease in lipid accumulation through the downregulation of several adipocyte specific-transcription factors, including CCAAT/enhancer binding protein β, C/EBPδ, and peroxisome proliferator-activated receptor gamma (PPARγ). Moreover, treatment with CCC during adipocyte differentiation induced a significant down-regulation of PPARγ and adipogenic target genes, including adipocyte protein 2, lipoprotein lipase, and adiponectin.

Sasa borealis stem extract attenuates hepatic steatosis in high-fat diet-induced obese rats.

The aim of the current study is to examine the improving effect of Sasa borealis stem (SBS) extract extracts on high-fat diet (HFD)-induced hepatic steatosis in rats. To determine the hepatoprotective effect of SBS, we fed rats a normal regular diet (ND), HFD, and HFD supplemented with 150 mg/kg body weight (BW) SBS extracts for five weeks. We found that the body weight and liver weight of rats in the HFD + SBS group were significantly lower than those in the HFD group.
