Menene tsarin aiki don GHK CU?
Inganta Rauni Warkar
Yadawa Kwayoyin Halitta da Hijira: GHK CU yana haɓaka haɓakawa da ƙaura na sel daban-daban, gami da fibroblasts fata da ƙwayoyin endothelial. Misali, a wuraren raunukan fata, yana hanzarta haɗa kayan matrix na waje kamar collagen da elastin ta fibroblasts, yana ba da tallafi na tsari don warkar da rauni. A lokaci guda, yana jan hankalin sel na endothelial don yin ƙaura zuwa ga rauni, yana haɓaka sabon samuwar jini. Wannan yana ba da wadataccen abinci mai gina jiki da iskar oxygen zuwa rauni, yana haɓaka tsarin warkarwa [1].
Ka'ida na Abubuwan Ci gaba: Wannan hadaddun yana daidaita magana da sakin abubuwan haɓaka da yawa, irin su canza yanayin girma-β (TGF-β) da haɓakar haɓakar haɓakar ƙwayoyin cuta (VEGF). Ɗaukar VEGF a matsayin misali, GHK CU yana inganta ɓoyayyen sa, wanda hakan ke haifar da yaduwar kwayar halitta ta jijiyoyi da kuma angiogenesis-mahimman matakai don warkar da rauni [1].
Abubuwan da ke hana kumburi
Inhibition of Inflammatory Mediators: GHK CU suppresses the production and release of multiple inflammatory mediators, including tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). Waɗannan masu shiga tsakani suna taka muhimmiyar rawa a cikin martani mai kumburi. Ta hanyar hana maganganun su, GHK CU yana rage ƙarfi da tsawon lokacin kumburi, ta haka yana rage lalacewar nama [2].
Modulation na Immune Cells: Hakanan yana daidaita aikin ƙwayoyin rigakafi. Ta hanyar daidaita macrophage polarization zuwa ga macrophages anti-mai kumburi, yana rage sakin masu shiga tsakani da inganta gyaran nama [2].
Gyaran DNA
Kunna Hanyoyin Gyara: GHK CU yana kunna hanyoyin gyaran DNA na ciki. Lokacin da kwayoyin halitta suka lalace ta hanyoyi daban-daban na endogenous ko na waje, suna fara jerin hanyoyin gyara DNA. GHK CU yana haɓaka gyaran DNA ɗin da ya lalace ta hanyar daidaita ayyukan enzymes masu alaƙa, kamar DNA polymerase da ligase, ta haka ne ke tabbatar da kwanciyar hankali na genomic [2].
Kariyar Antioxidant: Yana da ƙarfin maganin antioxidant, yana rage nau'in oxygen mai amsawa (ROS) lalacewa ta DNA. ROS na iya haifar da karyewar madaidaicin DNA da oxidation tushe. Ta hanyar zazzage ROS, GHK CU yana kare DNA a kaikaice daga lalacewa, ƙirƙirar yanayi masu kyau don gyaran DNA [1].
Gudanar da Ciwon Suga na Kwayoyin Halitta
Haɓaka Ciwon sukari na Makamashi: Game da metabolism na makamashin salula, GHK CU na iya rinjayar aikin mitochondrial. Mitochondria yana aiki azaman gidajen wutar lantarki, kuma GHK CU na iya haɓaka haɓakar samar da makamashi ta salula ta hanyar daidaita ayyukan enzymes masu alaƙa da mitochondrial-kamar waɗanda ke cikin zagayowar tricarboxylic acid da phosphorylation oxidative — don haka saduwa da buƙatun makamashi yayin tafiyar tafiyar salula kamar girma da gyara [2].
Ƙaddamar da Ƙimar Abu: GHK CU kuma tana daidaita haɗin mahimman abubuwa na ciki. Kamar yadda aka ambata a baya, yana haɓaka haɓakar abubuwan haɗin matrix na extracellular kamar collagen da elastin. Bugu da ƙari, yana rinjayar kira da metabolism na abubuwa na ciki kamar su sunadaran da lipids, ta haka ne ke ci gaba da aiki na al'ada na salon salula [2]..
Menene aikace-aikacen GHK CU?
Warkar da Rauni: GHK CU yana da ikon haɓaka warkar da rauni. Yana ƙarfafa angiogenesis, yana ba da wadataccen abinci mai gina jiki da iskar oxygen zuwa wurin rauni, ta haka yana haɓaka gyaran nama da sake farfadowa. GHK CU kuma yana goyan bayan aikin fibroblasts dermal, yana haɓaka haɓakar collagen, elastin, da glycosaminoglycans. Wannan yana taimakawa wajen gina matrix na waje mai lafiya kuma yana hanzarta aikin warkar da rauni. A cikin binciken Pickart L game da raunin fata, jiyya tare da GHK CU da ke ƙunshe da tsari yana haɓaka saurin warkar da rauni da ingantaccen ingancin warkarwa [2].
Ƙwararren Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararrun Ƙwararru. A cikin duka lipopolysaccharide (LPS) -induced m huhu rauni (ALI) linzamin kwamfuta model da kuma in vitro gwaje-gwaje tare da RAW 264.7 macrophages, GHK CU magani rage amsawa jinsunan oxygen (ROS) samar, ya karu superoxide dismutase (SOD) aiki, da kuma rage ƙarni na kumburi matsakanci irin su factor-αr necrosis -αr necrosis. (IL-6), wanda aka samu ta hanyar hana NF-κB p65 da p38 MAPK hanyoyin siginar. Don haka, GHK CU yana nuna yiwuwar warkewa don cututtukan da ke da alaƙa da kumburi kamar ALI/Acute Respiratory Distress Syndrome (ARDS) [3].
Kariyar salon salula: Yana Nuna tasirin kariyar salula da yawa. A cikin cututtuka na huhu na huhu (COPD), yana kare da gyara ƙwayar huhu yayin da yake dawo da aikin fibroblast COPD. Hakanan yana hana ƙwayoyin cuta kamar NFκB, waɗanda aka yi imani don haɓaka cututtukan tsufa, yana nuna yuwuwar rigakafin tsufa. Bugu da ƙari, yana nuna anti-damuwa, analgesic, da ayyukan anti-ta'addanci, kuma yana kunna ayyukan tsaftace salula ta hanyar tsarin proteasome, yana ba da cikakkiyar kariya ta salula [2] .
Gyaran DNA: GHK CU yana shiga cikin tsarin gyaran DNA na ciki na ciki, yana taimakawa wajen tabbatar da kwanciyar hankali na kwayoyin halitta da rage ilimin cututtuka na salula da kuma matsalolin tsufa da ke haifar da lalacewar DNA. Wannan yana goyan bayan rigakafi da maganin cututtukan da ke da alaƙa da lalacewar DNA [2].
Kammalawa
A matsayin hadadden trieptide-jan karfe na endogenous, GHK CU yana nuna ayyukan nazarin halittu masu yawa. Ta hanyar kunna hanyoyin sigina kamar PI3K/Akt da MAPK/ERK, yana haɓaka haɓakar fibroblast, angiogenesis, da haɓakar matrix na waje, suna taka muhimmiyar rawa wajen warkar da rauni. Har ila yau, yana nuna ayyukan anti-mai kumburi, antioxidant, da kuma immunomodulatory ayyuka, yana kawar da lalacewar nama da kuma taimakawa wajen gyaran gyare-gyare da kuma maganin cututtuka.
Game da Marubuci
Abubuwan da aka ambata a sama duk bincike ne, gyara su kuma Cocer Peptides ne suka haɗa su.

Loren Pickart sanannen masanin ilimin halittu ne kuma wanda ya kafa Skin Biology Inc., wanda ya kware a cikin nazarin peptides na jan karfe da aikace-aikacen su a lafiyar fata da tsufa. Ya gano peptide na jan karfe GHK CU a cikin 1973 yayin bincikensa na digiri na uku a Jami'ar California, San Francisco. Wannan binciken ya haifar da ci gaban fata peptides na jan ƙarfe da kuma kafa Skin Biology Inc. a cikin 1994. Ayyukansa sun ba da gudummawa sosai ga fahimtar ilimin halittun fata da haɓaka maganin tsufa. Binciken Pickart ya ci gaba da yin tasiri a fannin dermatology da magani na farfadowa.
