Jedn\u00fdm z v\u00fdrazn\u00fdch pozorovan\u00ed je, \u017ee prirodzen\u00e1 hladina GHK s vekom kles\u00e1.

Podporuje opravu tkan\u00edv zv\u00fd\u0161en\u00edm hlad\u00edn rastov\u00fdch faktorov, ako s\u00fa VEGF a bFGF. Tieto faktory podporuj\u00fa tvorbu nov\u00fdch krvn\u00fdch ciev a zlep\u0161uj\u00fa dod\u00e1vku kysl\u00edka a \u017eiv\u00edn do tkan\u00edv, najm\u00e4 do po\u0161koden\u00fdch alebo starn\u00facich.

Okrem toho ovplyv\u0148uje z\u00e1palov\u00e9 dr\u00e1hy, ako je NF-\u03baB a p38 MAPK.

\u010eal\u0161ou d\u00f4le\u017eitou oblas\u0165ou je regul\u00e1cia g\u00e9nov. \u0160t\u00fadie na aktivitu g\u00e9nov ukazuj\u00fa, \u017ee GHK m\u00f4\u017ee ovplyv\u0148ova\u0165 ve\u013ek\u00e9 mno\u017estvo \u013eudsk\u00fdch g\u00e9nov, najm\u00e4 tie, ktor\u00e9 s\u00favisia s opravou, z\u00e1palom a celkovou \u00fadr\u017ebou buniek.

V niektor\u00fdch \u0161t\u00fadi\u00e1ch GHK podporuje aj syst\u00e9m ubiquit\u00edn-proteaz\u00f3m. Tento syst\u00e9m je zodpovedn\u00fd za odstra\u0148ovanie po\u0161koden\u00fdch alebo nepotrebn\u00fdch prote\u00ednov, \u010do je d\u00f4le\u017eit\u00e9 pre udr\u017eanie zdrav\u00fdch buniek.

U starn\u00facich my\u0161\u00ed sa pozorovalo zn\u00ed\u017eenie z\u00e1palu a vplyv na epigenetick\u00e9 markery, ako je aktivita hist\u00f3novej deacetyl\u00e1zy. Tieto zmeny boli tie\u017e spojen\u00e9 so zlep\u0161en\u00edm schopnosti u\u010denia.

Ktor\u00e9 prejavy starnutia boli sk\u00faman\u00e9 v s\u00favislosti s meden\u00fdm tripeptidom GHK?<\/strong><\/h2>\n
\n

GHK-Cu bol analyzovan\u00fd v kontexte nieko\u013ek\u00fdch dobre zn\u00e1mych znakov starnutia. Tieto zah\u0155\u0148aj\u00fa procesy ako chronick\u00fd z\u00e1pal, oxida\u010dn\u00fd stres, bunkov\u00fa senescenciu, zn\u00ed\u017een\u00fa schopnos\u0165 odstra\u0148ova\u0165 po\u0161koden\u00e9 bielkoviny a pokles schopnosti tkan\u00edv opravova\u0165 a regenerova\u0165 sa. Hoci GHK-Cu nie je v\u017edy form\u00e1lne zahrnut\u00fd do klasick\u00e9ho modelu \u201eznakou starnutia\u201d, pozorovan\u00e9 \u00fa\u010dinky jeho p\u00f4sobenia zodpovedaj\u00fa mnoh\u00fdm k\u013e\u00fa\u010dov\u00fdm biologick\u00fdm zmen\u00e1m sk\u00faman\u00fdm v kontexte starnutia.<\/p>\n

Jednou z naj\u010dastej\u0161ie analyzovan\u00fdch oblast\u00ed je chronick\u00fd z\u00e1pal, \u010dasto ozna\u010dovan\u00fd ako \u201einflammaging\u201d. Bolo preuk\u00e1zan\u00e9, \u017ee GHK-Cu zni\u017euje hladiny proz\u00e1palov\u00fdch sign\u00e1lov, ako s\u00fa TNF-\u03b1 a IL-6. Ovplyv\u0148uje tie\u017e k\u013e\u00fa\u010dov\u00e9 dr\u00e1hy, ako s\u00fa NF-\u03baB a p38 MAPK, ktor\u00e9 sa podie\u013eaj\u00fa na imunitnej odpovedi organizmu. Ke\u010f\u017ee chronick\u00fd z\u00e1pal je spojen\u00fd s po\u0161koden\u00edm tkan\u00edv a rozvojom chor\u00f4b s\u00favisiacich s vekom, tento \u00fa\u010dinok sa pova\u017euje za v\u00fdznamn\u00fd vo v\u00fdskume starnutia.<\/p>\n

\u010eal\u0161ou d\u00f4le\u017eitou oblas\u0165ou je oxida\u010dn\u00fd stres. GHK-Cu p\u00f4sob\u00ed ako antioxidant, pom\u00e1ha neutralizova\u0165 reakt\u00edvne formy kysl\u00edka, ktor\u00e9 m\u00f4\u017eu \u010dasom po\u0161kodzova\u0165 bunky. Podporuje tie\u017e prirodzen\u00e9 obrann\u00e9 syst\u00e9my tela vr\u00e1tane enz\u00fdmov, ako je superoxiddismut\u00e1za (SOD) a zl\u00fa\u010den\u00edn, ako je glutati\u00f3n. Okrem toho m\u00f4\u017ee viaza\u0165 toxick\u00e9 ved\u013eaj\u0161ie produkty vznikaj\u00face pri oxid\u00e1cii lipidov, ako je akrole\u00edn a 4-hydroxynonen\u00e1l. Tieto l\u00e1tky sa \u010dasto sp\u00e1jaj\u00fa s po\u0161koden\u00edm buniek v starn\u00facich tkaniv\u00e1ch.<\/p>\n

GHK-Cu bol sk\u00faman\u00fd aj v kontexte bunkovej senescencie. Je to proces, pri ktorom bunky str\u00e1caj\u00fa schopnos\u0165 sa deli\u0165 a spr\u00e1vne fungova\u0165. V \u0161t\u00fadi\u00e1ch so star\u0161\u00edmi fibroblastmi bolo pozorovan\u00e9, \u017ee GHK zni\u017euje markery spojen\u00e9 so senescenciou, vr\u00e1tane p21 a p53. Z\u00e1rove\u0148 obnovil schopnos\u0165 buniek na pohyb a aktivitu. Podporil tie\u017e elimin\u00e1ciu nefunk\u010dn\u00fdch myofibroblastov prostredn\u00edctvom apopt\u00f3zy, \u010do je d\u00f4le\u017eit\u00e9 pri obmedzovan\u00ed fibr\u00f3zy, ktor\u00e1 sa \u010dasto vyskytuje v starn\u00facich tkaniv\u00e1ch.<\/p>\n

\u010eal\u0161ou charakteristikou starnutia je strata proteost\u00e1zy, teda zn\u00ed\u017eenie schopnosti organizmu odstra\u0148ova\u0165 po\u0161koden\u00e9 alebo nespr\u00e1vne zbalen\u00e9 bielkoviny. \u0160t\u00fadie nazna\u010duj\u00fa, \u017ee GHK m\u00f4\u017ee aktivova\u0165 zlo\u017eky syst\u00e9mu ubikvit\u00edn-proteaz\u00f3m, ktor\u00fd je zodpovedn\u00fd za odstra\u0148ovanie tak\u00fdchto bielkov\u00edn. Tento syst\u00e9m vekom oslabuje a s\u00favis\u00ed s ochoreniami, ako s\u00fa neurodegenerat\u00edvne choroby.<\/p>\n

Okrem toho sa zd\u00e1, \u017ee GHK-Cu ovplyv\u0148uje aktivitu kme\u0148ov\u00fdch buniek a procesy regener\u00e1cie tkan\u00edv. Bol sp\u00e1jan\u00fd so zv\u00fd\u0161enou expresiou markerov, ako s\u00fa p63 a PCNA, ktor\u00e9 s\u00favisia s rastom buniek a schopnos\u0165ou opravy. Podporuje tie\u017e procesy, ako je produkcia kolag\u00e9nu, tvorba nov\u00fdch krvn\u00fdch ciev (angiogen\u00e9za) a remodel\u00e1cia extracelul\u00e1rnej matrix. Tieto funkcie sa zvy\u010dajne vekom oslabuj\u00fa.<\/p>\n
