Cov Vitamin A (Retinol) Hmoov uas yaj tau hauv roj
Kev Taw Qhia Txog Khoom
Retinol (tseem hu ua retinol, Ib hom vitamin A) yog ib qho khoom noj khoom haus tseem ceeb rau tib neeg lub cev. Nws koom nrog hauv kev tsim cov hlwb pom thiab tseem ceeb rau kev tswj hwm kev ua haujlwm pom hauv qab lub teeb tsaus ntuj. Tib lub sijhawm, retinol tuaj yeem khi rau retinol binding protein (RBP) ntawm qhov chaw ntawm daim tawv nqaij thiab nkag mus rau hauv cov hlwb tawv nqaij los ntawm RBP receptors los tsim cov retinoic acid. Retinoic acid nkag mus rau hauv lub nucleus, sib xyaw nrog cov receptors cuam tshuam (RXR, RAR) los tsim ntau yam dimers, thiab sib xyaw nrog cov ntsiab lus teb retinoic acid sib xws nyob rau hauv kev pab ntawm activators (xws li histone acetyltransferase). Los ntawm kev tswj hwm thiab tswj hwm kev ua haujlwm thiab kev qhia tawm ntawm messenger RNA hauv lub nucleus, retinoic acid tswj hwm kev faib cell thiab kev sib txawv thiab txhawb nqa keratinocyte proliferation. Nws tuaj yeem txhawb nqa kev ua haujlwm ntawm keratinocytes hauv epidermis, txo qhov kev puas tsuaj ntawm collagen hauv dermis, thiab txhawb nqa fibroblasts los tsim ntau collagen thiab hyaluronic acid.
