Mimosine is a toxic nonprotein amino acid that is a major constituent of the tropical legumes Leucaena and Mimosa. Mimosine has been shown to cause acute and chronic toxicosis in livestock fed from forage containing these plants. Recently, mimosine has been demonstrated to reversibly block cell
Hormone replacement therapy has been a conventional treatment for postmenopausal symptoms in women. However, it has potential risks of breast and endometrial cancers. The aim of this study was to evaluate the oestrogenicity of a plant-based compound, mimosine, in MCF-7 cells by in silico model. Cell
Tumor suppressor p53 is a nuclear protein that is induced by DNA damage and is involved in G1 and G2 phase control of the cell cycle. p21WAF1/CIP1/SDI1 (p21), a cyclin-dependent kinase inhibitor, is a downstream target and effector of p53 to induce G1 arrest. Mimosine is a potent reversible late G1
Most breast cancers occur sporadically due to long-term exposure to low-dose carcinogens in the diet and the environment. Specifically, smoke, polluted air, and high-temperature cooked meats comprise multiple carcinogens, such as 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), benzo[α]pyrene
Iron chelation, known to block progression through the cell cycle, was examined for effects on the activity and subunit levels of the cyclin-dependent protein kinases (cdk). Treatment of asynchronous MDA-MB-453 cells with the iron chelators mimosine or desferrioxamine (DFO) for 24 h stopped cell
The plant amino acid mimosine has been reported to block cell cycle progression in the late G1 phase. A recent study showed that mimosine might induce growth arrest by activating the expression of p21CIP1, a cyclin-dependent kinase inhibitor (CDKI), and by inhibiting the activity of cyclin
Translation initiation in eukaryotes is a rate-limiting step in protein synthesis. It is a complicated process that involves many eukaryotic initiation factors (eIFs). Altering the expression level or the function of eIFs may influence the synthesis of some proteins and consequently cause abnormal
