Cov ntsiab lus kev paub
Nws tus nqi tseem ceeb yog tshem tawm "zombie hlwb" thiab txhim kho cov leeg nqaij ib puag ncig. High- kev cob qhia siv zog ua kom cov leeg nqaij senescence. Cov hlwb senescent no (feem ntau hu ua "zombie cells") tsis sib faib tab sis tsis tu ncua zais cov kab mob inflammatory (SASPs), cuam tshuam nrog kev ua haujlwm ntawm cov leeg nqaij satellite (core qia hlwb rau cov leeg nqaij), ua rau cov nqaij ntshiv stagnation thiab ntev rov ua haujlwm. FOXO4 sib tw khi rau p53 protein, pib txoj hauv kev mitochondrial apoptosis hauv cov hlwb senescent, meej meej tshem tawm cov teeb meem senescent yam tsis ua rau cov leeg nqaij noj qab haus huv. Qhov no tsim kom muaj ib puag ncig huv si rau kev kho cov leeg nqaij, pab cov neeg ncaws pob tawg los ntawm cov leeg nqaij - txhim kho toj siab.https://www.fiercerawsource.com/peptides/premium-high-purity-peptides-foxo4.html
Nws cov haujlwm tseem ceeb kuj suav nrog inhibiting cov leeg nqaij atrophy thiab txhim kho kev kawm endurance. FOXO4 tuaj yeem tswj hwm qhov kev qhia ntawm ubiquitin ligases MAFbx thiab MuRF1, ob lub ntsiab lus tseem ceeb ntawm cov leeg nqaij leeg. Thaum lub sij hawm poob rog lossis siab - kev siv zog hloov pauv, FOXO4 tuaj yeem txo cov leeg nqaij thiab tswj cov leeg nqaij thiab lub zog los ntawm inhibiting cov haujlwm ntawm ob lub enzymes. Nyob rau tib lub sijhawm, nws tuaj yeem txhim kho cov leeg nqaij mitochondrial muaj nuj nqi, txhim kho lub zog tsim hluav taws xob, txo kev qaug zog thaum lub sij hawm kev cob qhia, thiab pab cov neeg ncaws pob ua tau siab dua - siv zog, siab dua - zaus kev hloov pauv.
Tsis tas li ntawd, FOXO4's lipid metabolism kev tswj muaj peev xwm ua tau raws li kev xav tau ntawm lub cev. Cov kev tshawb fawb tau pom tias FOXO4 tuaj yeem txhim kho qhov kev qhia ntawm cov noob muaj feem xyuam rau lipolysis, txhawb cov metabolism hauv cov rog subcutaneous, thiab pab cov neeg ncaws pob kom txo tau cov rog hauv lub cev feem pua ntawm kev sib tw, qhia txog cov leeg nqaij. Tam sim no, kev tsim lub cev siv dav siv FOXO4 derivatives (xws li FOXO4-DRI), uas nws cov cell nkag tau zoo dua thiab qhov tshwj xeeb ua rau muaj kev tshem tawm cov hlwb zoo dua, ua rau nws muaj txiaj ntsig zoo rau kev tawg los ntawm cov leeg nqaij pob txha thiab txhim kho kev sib tw kev sib tw.
