Amyloid-β
β-amyloid peptide; Aβ; Abeta
Amyloid-β (Aβ) denotes peptides of 36–43 amino acids that are crucially involved in Alzheimer's disease as the main component of theamyloid plaques found in the brains of Alzheimer patients. The peptides result from the amyloid precursor protein (APP), which is being cut by certain enzymes to yield Aβ. Amyloid-β molecules can aggregate to form flexible soluble oligomers which may exist in several forms. Amyloid-β peptide is due to overproduction of Aβ and/or the failure of clearance mechanisms. Amyloid-β self-aggregates into oligomers, which can be of various sizes, and forms diffuse and neuritic plaques in the parenchyma and blood vessels. Amyloid-β oligomers and plaques are potent synaptotoxins, block proteasome function, inhibit mitochondrial activity, alter intracellular Ca2+levels and stimulate inflammatory processes. Loss of the normal physiological functions of Aβ is also thought to contribute to neuronal dysfunction.

Theasaponin E1
0 ImagesTheasaponin E1 is an orally effective tea saponin. Theasaponin E1 inhibits the proliferation of cancer cells by activating apoptosis. Theasaponin E1 inhibits angiogenesis in ovarian cancer cells and HUVECs by reducing the expression of VEGF. Theasaponin E1 upregulates the phosphorylation level of ATM protein and the expression level of PTEN protein in cancer cells, decreases the phosphorylation levels of Akt, mTOR, p70S6K and 4E-BP1 proteins, downregulates the expression of HIF-1α and NF-κB, and reduces the protein expression of Notch ligands Dll4 and Jagged1. Theasaponin E1 exerts neuroprotective effects by inhibiting the activity of acetylcholinesterase, activating α-secretase and neprilysin, reducing the concentration of Aβ, and inhibiting the activities of β-secretase and γ-secretase. Theasaponin E1 exhibits toxic effects on cancer cells and quinone reductase-inducing activity, and inhibits tumor growth in vivo. Theasaponin E1 induces ferroptosis in Pomacea canaliculata by synergistically disrupting cholesterol homeostasis and sphingolipid metabolism. Theasaponin E1 possesses anti-biofilm activity against Candida albicans. Theasaponin E1 can be used in the research of ovarian cancer, obesity, Alzheimer's disease and fungal infections.
