Eurycomanone is a chemical compound that has been isolated from Eurycoma longifolia, also known as the longjack plant or tongkat ali. [1] Eurycomanone is distributed throughout the plant, with the highest concentration in leaves. Researchers measured 6.0568 μg/mL in leaves, and only 0.3533 μg/mL in roots. [2]
Eurycoma longifolia (commonly called tongkat ali, Malaysian ginseng or long jack) [3] is a flowering plant in the family Simaroubaceae. It is native to Indochina (Cambodia, Laos, Malaysia, Myanmar, Thailand and Vietnam) and Indonesia (the islands of Borneo and Sumatra ), [ 4 ] but has also been found in the Philippines. [ 5 ]
However, the amount Tongkat Ali raises T levels is not to any significant effect. “For most guys, it’s only going to raise your levels 30 points or so, which isn’t enough to meaningfully ...
DNA damage inhibits M-CDKs which are a key component of progression into mitosis. In all eukaryotic cells, ATR and ATM are protein kinases that detect DNA damage. They bind to DNA damaged sites and activate Chk1, Chk2, and, in animal cells, p53. Together, these proteins make up the DNA damage response system.
Reactive oxygen species modify the mechanism of epigenetic methylation by inducing DNA breaks which are later repaired and then methylated by DNMTs. DNA damage response genes, such as GADD45A, recruit nuclear proteins Np95 to direct histone methyltransferase's towards the damaged DNA site. The breaks in DNA caused by the ionizing radiation then ...
Nucleotide excision repair (NER) is a particularly important excision mechanism that removes DNA damage induced by ultraviolet light (UV). UV DNA damage results in bulky DNA adducts — these adducts are mostly thymine dimers and 6,4-photoproducts. Recognition of the damage leads to removal of a short single-stranded DNA segment that contains ...
DNA damage checkpoint is a signal transduction pathway that blocks cell cycle progression in G1, G2 and metaphase and slows down the rate of S phase progression when DNA is damaged. It leads to a pause in cell cycle allowing the cell time to repair the damage before continuing to divide.
A woman who underwent a trial immunotherapy as a child for neuroblastoma — an aggressive nerve tissue tumor that occurs often in children under 5 — has since been in remission for 18 years ...
