ATM/ATR
Ataxia telangiectasia mutated; ATM and RAD3 related
ATM/ATR, members of the phosphatidyl inositol 3-kinase-like family of serine/threonine protein kinases (PIKKs), are widely known as being central players in the mitotic DNA damage response (DDR), mounting responses to DNA double-strand breaks (DSBs) and single-stranded DNA (ssDNA) respectively. Activation of ATM by ionizing radiation results in the activation of signal transduction pathways that induce cell cycle arrest at G1/S, S and G2/M. ATR is required for cell cycle arrest in response to DNA-damaging agents such as ultraviolet radiation that cause bulky lesions.
Upon activation, ATM/ATR phosphorylate numerous targets to stabilize stalled replication forks, repair damaged DNA, and inhibit cell cycle progression to ensure survival of the cell and safeguard integrity of the genome. ATM and ATR are central players in activating cell cycle checkpoints and function as an active barrier against genome instability and tumorigenesis in replicating cells.

Hexapeptide-11
0 ImagesHexapeptide-11 is an anti-aging peptide that can protect fibroblasts from premature cell senescence mediated by oxidative stress. Hexapeptide-11 is also a potential stimulator of hyaluronic acid in keratinocytes, and can enhance skin barrier function by upregulating the expression of HAS2 and EGR3, and downregulating the expression of HYAL2. Hexapeptide-11 can also improve skin elasticity.

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.
