CTP: phosphocholine cytidylyltransferase α (CCTα) o se enzyme faaniukilia lea e faʻapipiʻiina le laasaga faʻatapulaʻaina i le auala CDP-choline mo le phosphatidylcholine (PC) synthesis.Lipid activation o le CCTα iu i lona faaliliuina atu i le teutusi faaniukilia ma le faalauteleina o se intranuclear membrane network taʻua o le nucleoplasmic reticulum (NR) e ala i se masini e aafia ai le deformation membrane.E manaʻomia foʻi lamina faʻamalosi mo le mautu ma le faʻateleina o le NR, ae pe o lenei fausaga tulaga ese, poʻo le lamina faaniukilia lautele, e manaʻomia mo le faʻaogaina o le PC e le o iloa.Ina ia suʻesuʻeina lenei mafutaga, o le lamina faaniukilia na faʻaumatia e le RNAi pe faʻalavelaveina e le faʻaaliga o le Hutchinson-Gilford progeria syndrome (HGPS) mutant lamin A (progerin), ma o le aʻafiaga i le CCTα ma le choline metabolism na suʻesuʻeina.siRNA-mediated silencing o le lamin A / C poʻo le lamin B1 i CHO sela e faʻaitiitia ai le NR e leai se aoga i le faʻapipiʻiina o le PC, aʻo faʻalua le tuʻituʻi e le faʻapitoa e taofia ai le ala.O le faʻamaoniaina o lana matafaioi laʻititi i le faʻapipiʻiina o le PC, naʻo le 10% o le choline / ethanolamine phosphotransferase le tumau na maua i le NR.I sela CHO, CCTα sa nucleoplasmic ma faʻatasi ma le GFP-progerin i gauga faaniukilia ma invaginations;ae ui i lea, o le HGPS fibroblasts na faʻaalia ai le tufatufaina atu o le CCTα i le cytoplasm ma le teutusi faaniukilia lea na faʻatasi ma le faʻaitiitia o le 2-fold i le PC synthesis.E ui lava i le suiga o le localization, choline-labeling experiments na faʻaalia ai e leʻi aʻafia le CCT, ma o le faʻalavelaveina o le faʻaogaina o le PC na maua i le faʻaitiitia o le gaioiga a le hemicholinium-sensitive choline transporter.Matou te faʻauʻuina o le CCTα ma le lamine e galulue faʻatasi e fausia le NR, ae o le aotelega o le fausaga o le teutusi faaniukilia e itiiti sona aʻafiaga i le CCT ma le PC synthesis.
