Chidzidzo cheChimurenga chinofumura Basa rePirin Protein muQuercetin Metabolism, Kutsanangura Patsva Mafambiro eSerura
Nyamavhuvhu 11, 2025 - Chidzidzo chakakosha chakabudiswa muMolecular Pharmacology chakapidigura makumi emakore ekubvumirana kwesainzi nekuburitsa kuti protein yePirin haidzore NF-κB nzira yekusaina sezvaimbotendwa. Pane kudaro, vaongorori vakawana kuti Pirin inoshanda se quercetinase - enzyme inogadzika iyo flavonoid quercetin - kuwanikwa kunogona kugadzirisa manzwisisiro edu ekuzvimba, kenza, uye metabolic regulation.
Kuwanikwa Kusingatarisirwi
Kwemakore, Pirin yaifungidzirwa kuva co-activator yeNF-κB nzira, mutongi anokosha wemhinduro dzekuzvidzivirira uye kuzvimba. Zvisinei, boka rekutsvakurudza rakatungamirirwa naDr. Meschkewitz kuMichigan State University harina kuwana uchapupu hwePirin hunosunga p65 (kiyi NF-κB subunit), pasinei nekuedza kakawanda kushandisa pamusoro peplasmon resonance (SPR), size-exclusion chromatography (SEC), uye fluorescence polarization (FP) miedzo.
Pane kudaro, chidzidzo chacho chakaratidza kuti Pirin inonyanya kuiswa munzvimbo ye endoplasmic reticulum (ER), iyo inosvibisa quercetin-ine simba antioxidant inowanikwa muzvokudya zvakadai semaapuro, hanyanisi, uye majiroji. Chikwata chakacherekedza CCG-257081, diki-morekuru inhibitor iyo inokwikwidza inovharira chiitiko chePirin's quercetinase, zvichikonzera kuwedzera kukuru kweiyo intracellular quercetin mazinga.
Zvinoreva Hutano uye Chirwere
Quercetin yakagara ichidzidzwa nekuda kwayo inopesana nekuputika, antioxidant, uye inogona kuita anticancer properties. Kuwanikwa uku kunoratidza kuti Pirin inogona kuita basa rakakosha mukugadzirisa quercetin's bioavailability mumaseru, izvo zvinogona kukanganisa mamiriro akaita senge kusingaperi kuzvimba, neurodegeneration, uye kunyangwe kukura kwegomarara.
"Kuwana uku kunotimanikidza kuti tifunge zvakare kuti quercetin inodzorwa sei mumuviri," akadaro Dr. Lisabeth, munyori pamwe chete wekudzidza. "Kana Pirin ikadzora kuderera kwequercetin, ipapo kuvharidzira Pirin kunogona kusimudzira mhedzisiro yequercetin yekurapa-chimwe chinhu chatiri kuongorora mumhando dzepamberi."
Ndiani anofanira kudzivisa quercetin?
Kunyanya kuwandisa kwequercetin kunogona kukuvadza itsvo. Iwe unofanirwa kutora nguva nenguva kubva pakutora quercetin. Vakadzi vane pamuviri, vakadzi vanoyamwisa, uye vanhu vane chirwere cheitsvo vanofanira kudzivisa quercetin. Pamadosi makuru kupfuura 1 g pazuva, kwave nemishumo yekukuvadzwa kweitsvo.
Ndinogona kutora quercetin nevhitamini D pamwechete?
Hongu, quercetin uye vhitamini D zvinogona kutorwa pamwechete. Muchokwadi, zvimwe zvidzidzo zvinoratidza kuti vanogona kutoshanda pamwe chete kutsigira hutano hwekudzivirira zvirwere. Quercetin, flavonoid inowanikwa mumichero yakawanda nemiriwo, uye vhitamini D, chikafu chinotsigira immune function uye hutano hwemaserura, inogona kuwanikwa mumubatanidzwa wekuwedzera.
Chii chaunofanira kudzivisa kana uchitora quercetin?
Ngwarira kana uri kutora zvinodhaka zvakadai semishonga inorwisa mabhakitiriya, cyclosporine, warfarin, kana mishonga inochinjwa nechiropa. Quercetin inogona kushandura mashandisirwo emishonga iyi uye kusimudza njodzi yemhedzisiro. Ikoko kunoratidzika kunge kuine kudyidzana pakati pequercetin uye chikafu kana mamwe maruva uye ekuwedzera.
Ko quercetin yakachengeteka kuvana here?
Kunyange zvazvo quercetin ichiwanika muzvokudya zvakawanda uye inowanzoonekwa seyakachengeteka kune vanhu vakuru muhuwandu hune mwero, pane tsvakurudzo shoma pamusoro pekuchengetedzwa kwayo uye kushanda kwevana, uye kungwarira kunorayirwa.
Nguva yekutora quercetin?
Iwe unogona kutora quercetin chero nguva yezuva. Nekudaro, iwe unofanirwa kufunga nezvekuitora panguva yekudya nekuti chikafu chine vhitamini C, bromelain, uye mafuta ane hutano zvinogona kubatsira kutora kwayo. Uyezve, “vamwe vanhu vangasarudza kuinwa pamwe chete nezvokudya kuti vaderedze kusagadzikana kungava kwomudumbu,” anodaro Dr. Ormond.
