Ni izihe ngaruka n'imikorere by'ubumaji bya urolithine A? Ni ibihe bicuruzwa byongewemo

 Urolithin A ni ikintu cy'ingenzi gikoreshwa cyane mu buvuzi no mu buvuzi. Ni enzyme ikorwa ahanini n'impyiko kandi ifite akazi ko gushonga amaraso. Ingaruka n'imikorere bya Urolithin A bigaragarira cyane muri ibi bikurikira.

Urolithine A irinda kwangirika kw'imitsi

1. Guteza imbere imikorere ya poroteyine mu mitsi no gukora inzira yo gutanga amakuru ya mTOR

Uburyo inyamaswa zo mu bwoko bwa rapamycin (mTOR) zikoresha mu gutanga ibimenyetso ni inzira y'ingenzi yo kugenzura imikorere ya poroteyine mu mitsi. Urolithin A ishobora gukora mu gutanga ibimenyetso bya mTOR no guteza imbere imikorere ya poroteyine mu turemangingo tw'imitsi.

mTOR ishobora kumva ibimenyetso nk'intungamubiri n'ibintu bikura mu turemangingo. Iyo ikoze, izatangiza urukurikirane rw'uturemangingo tw'ibimenyetso duto, nka poroteyine ya ribosomal S6 kinase (S6K1) na poroteyine 1 ifata eukaryotic factor 4E (4E-BP1). Urolithin A ikora mTOR, ikora fosforilati S6K1 na 4E-BP1, bityo igateza imbere gutangiza kwa mRNA no guteranya ribosome, kandi ikihutisha imikorere ya poroteyine.

Urugero, mu bushakashatsi bwakozwe ku turemangingo tw’imitsi twakuwe muri vitro, nyuma yo kongeramo urolithine A, byagaragaye ko urugero rwa fosforasi rwa mTOR n’uturemangingo tw’amakuru two hasi byiyongeraga, kandi ibimenyetso bya poroteyine mu mitsi (nk’urunigi ruremereye rwa myosin) byiyongeraga.
Igenzura imikorere y'imitsi mu buryo bwihariye

Muri icyo gihe, urolithin A ishobora kandi kunoza imikorere y’uruhererekane rw’ubuhumekero rwa mitochondrial, yongera imikorere ya adenosine triphosphate (ATP), igatanga ingufu zihagije zo gutuma imitsi ifungana, kandi ikagabanya kugabanuka kw’imitsi guterwa n’ingufu nke.

Igenzura imikorere y'isukari n'amavuta kandi igashyigikira imikorere y'imitsi

Urolithine A ishobora kugenzura imikorere ya glucose na lipid mu turemangingo tw’imitsi. Ku bijyanye n’imikorere ya glucose, ishobora kongera uburyo glucose itwarwa n’ikoreshwa n’uturemangingo tw’imitsi, kandi ikagenzura ko uturemangingo tw’imitsi tugira ingufu zihagije binyuze mu gukoresha inzira yo gutanga ibimenyetso bya insuline cyangwa izindi nzira zo gutanga ibimenyetso zijyanye no gutwara glucose.

Ku bijyanye n'imikorere y'ibinure mu mubiri, urolithine A ishobora guteza imbere okiside y'ibinure, igatanga indi soko y'ingufu zo kugabanya imitsi. Mu kunoza imikorere y'ibinure mu mubiri no mu mikorere y'ibinure mu mubiri, urolithine A ikomeza gutanga ingufu mu turemangingo tw'imitsi kandi igafasha gukumira ko imitsi igabanuka.

Urolithine A ifasha mu kongera imikorere y'umubiri

1. Kugenzura uburyo isukari ikoreshwa mu gukora isuku no kunoza uburyo insuline ikoreshwa mu gukora isuku
Urolithin A ishobora kongera ubushobozi bwo kumva insuline, ikaba ari ingenzi mu kubungabunga isukari mu maraso. Ishobora gukora ku bintu by'ingenzi biri mu nzira yo gutanga ibimenyetso bya insuline, nka poroteyine za insuline receptor substrate (IRS).

Mu gihe insuline idashobora gukora neza, phosphorylation ya tyrosine ya poroteyine ya IRS irahagarikwa, bigatuma inzira y'ikimenyetso cya phosphatidylinositol 3-kinase (PI3K) inanirwa gukora neza, kandi uburyo ak'uturemangingo tuyifatamo bugabanuka.

Urolithin A ishobora guteza imbere phosphorylation ya tyrosine ya poroteyine ya IRS, bityo igakoresha inzira y'ibimenyetso ya PI3K-protein kinase B (Akt), bigatuma uturemangingo dushobora kwinjiza no gukoresha glucose neza. Urugero, mu bushakashatsi bw'ingero z'inyamaswa, nyuma yo guhabwa urolithin A, ubushobozi bw'imitsi n'ibinure ku mubiri bya insuline bwarushijeho kuzamuka cyane, kandi urugero rw'isukari mu maraso rwaragenzuwe neza.

Igenzura ikorwa rya glycogen n'iyangirika

Glycogen ni yo nzira nyamukuru yo kubika isukari mu mubiri, cyane cyane mu mwijima no mu mitsi. Urolithin A ishobora kugenzura uburyo glycogen ikorwa n'uburyo ibora. Ishobora gukora synthase ya glycogen, igateza imbere uburyo glycogen ikorwa, kandi ikongera uburyo glycogen ibikwamo.

Muri icyo gihe, urolithine A ishobora kandi kubuza imikorere ya enzymes za glycogenolytic, nka glycogen phosphorylase, no kugabanya ingano ya glycogen ihinduka glucose ikajya mu maraso. Ibi bifasha gutuza urugero rw'isukari mu maraso no gukumira ihindagurika rikabije ry'isukari mu maraso. Mu bushakashatsi bwakorewe kuri diyabete, nyuma yo kuvurwa na urolithine A, ingano ya glycogen mu mwijima no mu mitsi yariyongereye, kandi kugenzura isukari mu maraso byaranogeye.

2. Kongera uburyo umubiri ukoresha ibinure mu mubiri no gukumira ikorwa rya aside irike

Urolithine A igira ingaruka ku ikorwa ry’ibinure mu mubiri. Mu mwijima no mu ngirabuzimafatizo z’amavuta, ishobora kubuza imisemburo y’ingenzi mu ikorwa ry’ibinure mu mubiri, nka synthase y’ibinure mu mubiri (FAS) na acetyl-CoA carboxylase (ACC).

FAS na ACC ni enzymes z'ingenzi zigenzura mu ikorwa rishya rya aside irike. Urolithin A ishobora kugabanya ikorwa rya aside irike ibuza imikorere yazo. Urugero, mu icyitegererezo cy'umwijima w'ibinure biterwa n'indyo irimo ibinure byinshi, urolithin A ishobora kugabanya imikorere ya FAS na ACC mu mwijima, ikagabanya ikorwa rya triglycerides, bityo ikagabanya ubwiyongere bw'ibinure mu mwijima.

Itera imbere ogisijeni y'aside irike

Uretse kubuza ikorwa rya aside irike, urolithine A ishobora kandi guteza imbere ibora rya aside irike. Ishobora gukora inzira z'ibimenyetso n'imisemburo bifitanye isano na ibora rya aside irike. Urugero, ishobora kongera imikorere ya carnitine palmitoyltransferase-1 (CPT-1).

CPT-1 ni enzyme y'ingenzi mu gutera aside irike β-oxidation, ishinzwe gutwara aside irike muri mitochondria kugira ngo oxidation ibore. Urolithin A itera imbere gutera β-oxidation ya aside irike binyuze mu gukora CPT-1, yongera ingufu zikoreshwa mu gutwika ibinure, ifasha kugabanya ububiko bw'ibinure mu mubiri, kandi ikanateza imbere imikorere y'ibinure mu mubiri.

Urolithin A ishobora kuyobora uturemangingo kugira ngo duhindure imikorere ya metabolic, bigatuma metabolic y’uturemangingo irushaho gukora neza. Mu bihe bimwe na bimwe by’imihangayiko cyangwa indwara, imiterere ya metabolic y’uturemangingo ishobora guhinduka, bigatuma imikorere igabanuka mu gukora ingufu no gukora ibintu.

Urolithin A ishobora kugenzura inzira zo gutanga ibimenyetso mu turemangingo, nk'inzira yo gutanga ibimenyetso ya AMP-activated protein kinase (AMPK). AMPK ni "sensor" y'imikorere y'ingufu z'uturemangingo. Nyuma y'uko urolithin A ikoresheje AMPK, ishobora gutuma turemangingo tuva kuri anabolisme tujya kuri catabolisme, tugakoresha neza ingufu n'intungamubiri, bityo bikanoza imikorere y'imikorere y'ingufu muri rusange.

Gukoresha urolithine A ntibigarukira gusa ku rwego rw'ubuvuzi. Bigenda birushaho kwitabwaho buhoro buhoro mu bikoresho by'ubuzima n'amavuta yo kwisiga. Urolithine A yongerwa ku bikoresho byinshi by'ubuzima kugira ngo yongere ubudahangarwa bw'umubiri, yongere amaraso atembera neza kandi ateze imbere imikorere y'umubiri. Ibi bikoresho akenshi biba biri mu buryo bwa capsules, ibinini cyangwa ibinyobwa, bikwiranye n'ibyo abantu batandukanye bakeneye.

Mu rwego rw'ubwiza bw'uruhu, urolithin A ikoreshwa cyane mu bikoresho byo kwita ku ruhu bitewe n'uko ihindura uturemangingo ndetse n'ubushobozi bwayo bwo kurwanya gusaza. Ishobora kunoza urujya n'uruza rw'amaraso mu ruhu no guteza imbere imikorere ya collagen, bityo ikarushaho kunoza uruhu no kurumurika. Ibigo byinshi byo kwita ku ruhu byo ku rwego rwo hejuru byatangiye gukoresha urolithin A nk'ikintu cy'ingenzi mu gutangiza ibikoresho birwanya gusaza, gusana no koroshya uruhu kugira ngo bihuze n'abaguzi bashaka uruhu rwiza.

Mu gusoza, nk'ikintu gifasha mu buzima gifite imirimo myinshi, urolithin A yagaragaje amahirwe menshi yo gukoreshwa mu rwego rw'ubuvuzi, ubuvuzi n'ubwiza. Uko ubushakashatsi bwa siyansi bugenda bwiyongera, urusobe rw'ikoreshwa rya urolithin A ruzakomeza kwaguka, rutange amahitamo menshi ku buzima bw'abantu n'ubwiza bwabo.
