Kedu ihe ndabere nyocha nke MOTS-C?

Mitochondria, na-eje ozi dị ka 'ụlọ ike' nke mkpụrụ ndụ, na-arụ ọrụ dị mkpa n'ịkwado homeostasis cellular. Usoro nzikọrịta ozi n'etiti mitochondria na nucleus bụ ogologo oge nyocha nke sayensị. Mitochondria nwere genome nọọrọ onwe ya. Na agbanyeghị mkpụrụ ndụ ihe nketa 37, nchọpụta ndị na-adịbeghị anya ekpughere na mitochondrial DNA na-etinyekwa peptides dị mkpụmkpụ na-arụ ọrụ nke ndụ, otu n'ime ha bụ peptide MOTs-C nke mitochondrial enwetara, nke mpaghara mitochondrial 12S rRNA debere. Nchọpụta a na-agbasawanye ohere nke mkpụrụ ndụ ihe nketa mitochondrial nke ukwuu, na-enye echiche ọhụụ maka ịkọwapụta usoro ndu dị oke mkpa dị ka nkwurịta okwu mitochondrial-nuklear na usoro metabolic.

Ka ọ dị ugbu a, ọgwụgwọ maka ọtụtụ ọrịa na-ama aka dị ka metabolism na ịba ọcha n'anya B na-eche nnukwu nsogbu ihu. Ọrụ a ma ama MOTS-C na nhazi usoro metabolic nke akwara skeletal, dị ka ịkwalite glucose metabolism, na-egosi ikike ọ nwere n'ịgwọ ọrịa metabolic. Ọzọkwa, ọkwa MOTs-C na-adịghị mma a na-ahụ na usoro ọrịa dị iche iche emeela ka ndị nchọpụta nyochaa ọrụ ya na mmalite ọrịa, ọganihu, na ọgwụgwọ, na-achọ ụzọ ọhụrụ iji merie ọnọdụ ndị a na-adịghị agwụ agwụ.

Kedu usoro eji arụ ọrụ maka MOTS-C?

Na-ahazi Ụzọ nrịbama metụtara ọrịa shuga

Na-eme ka ụzọ mgbaama AICAR-AMPK rụọ ọrụ: MOTs-C na-arụ ọrụ ụzọ akara AICAR-AMPK site na imebi okirikiri folate-methionine intracellular. AMPK arụ ọrụ na-achịkwa metabolism ike cell, dị ka ịkwalite nnabata glucose na oxidation fatty acid. N'ime glucose metabolism, ọ na-abawanye ntụgharị nke GLUT4 na-ebu glucose na akpụkpọ ahụ, si otú ahụ na-eme ka ikike nnabata glucose dịkwuo elu, na-eme ka nguzogide insulin dịkwuo elu, na inye aka na mgbochi na ọgwụgwọ nke ọrịa metabolic dị ka ụdị 2 metabolism ^[1]..

Mmetụta na ụzọ ndị ọzọ: E wezụga ụzọ AMPK, MOTs-C na-arụkwa ọrụ na ụzọ AKT, ụzọ nrụgide oxidative, na ụzọ metụtara mbufụt. Banyere ụzọ AKT, ọ nwere ike imetụta usoro cellular dị ka uto, mmụba, na nlanarị site na ịhazi ọrụ nke ụzọ ahụ. N'okporo ụzọ nrụgide oxidative, MOTs-C na-ebelata ọkwa nrụgide oxidative intracellular, na-ebelata mmepụta ụdị oxygen (ROS), ma na-echebe mkpụrụ ndụ site na mmebi oxidative. N'ụzọ ndị metụtara mbufụt, ọ na-ebelata ntọhapụ nke ndị mgbasa ozi na-egbuke egbuke ma na-ebelata nzaghachi mkpali. Dịka ọmụmaatụ, n'ụdị mgbu na-egbuke egbuke, MOTs-C na-ebelata mwepụta onye mgbasa ozi mkpali na mpi dorsal nke ọkpụkpụ azụ, si otú ahụ na-emeziwanye mgbaàmà mgbu ^[2]..

Ọgụgụ 1 Ọrụ izizi nke MOTs-C gụnyere ibelata nguzogide insulin, igbochi oke ibu, melite ọrụ akwara, ịkwalite metabolism nke ọkpụkpụ, ịkwalite usoro mgbochi ọrịa, na igbu oge ịka nká ^[1].

Iwu nke okwu Gene

Usoro Nkwuwapụta Gene Nuklia: Mgbe mkpụrụ ndụ na-ezute nrụgide metabolic, dị ka mmachi glucose na nrụgide oxidative, MOTs-C na-atụgharị na nucleus ka ọ na-ahazi okwu mkpụrụ ndụ ihe nketa nuklia ozugbo, si otú ahụ na-akwalite homeostasis intracellular. Dịka ọmụmaatụ, MOTs-C na-agbanwe okwu nke mkpụrụ ndụ ihe nketa metụtara metabolism dị ka GLUT4, STAT3, na IL-10, na-emetụta usoro ọmụmụ physiological gụnyere glucose metabolism na usoro mgbochi. Mmụba okwu GLUT4 na-eme ka nnabata glucose dị n'ọbara; STAT3 na-ekere òkè n'ịba ụba nke cell, dị iche iche, na usoro nchịkwa; IL-10, cytokine na-egbochi mkpali, na-ebelata nzaghachi mkpali mgbe a na-ebuli okwu ya elu ^[1,3].

Ịkwalite ọrịa shuga mellitus

Glycolysis emelitere: N'ụdị ọrịa dị iche iche, dị ka ngụgụ ischemia-reperfusion mmerụ (LIRI) ụdị nke na-akpata site cardiopulmonary bypass (CPB), MOTs-C pretreatment na-eme ka glycolytic flux na pulmonary microvascular endothelial cell (PMVECs). Ọ na-ebelata mmerụ ahụ LIRI site na iweghachi homeostasis ume cell yana ibelata peroxidation lipid site na ịkwalite isi glycolytic enzyme PFKFB3. Nke a na-egosi na MOTs-C na-agbanwe ụzọ glycolytic iji nye ike zuru oke maka mkpụrụ ndụ nọ n'okpuru nrụgide, si otú a na-ejigide ọrụ cellular nkịtị ^[4]..

Mmetụta Nchekwa Cellular

Mbelata nke mmebi Mitochondrial: N'ụdị pneumonitis radieshon (RP), MOTs-C belatara mmerụ ahụ anụ ahụ nku ume, mbufụt, na nrụgide oxidative mgbe ọ na-atụgharị alveolar epithelial cell apoptosis na mmebi mitochondrial. Usoro a na-agụnye ịbawanye ọkwa 2 (Nrf2) metụtara ihe nuklia E2 na ịkwalite ntụgharị nuklia ya. Nrf2 na-arụ ọrụ usoro antioxidant na mkpụrụ ndụ ihe nchebe cell, na-echekwa ọrụ mitochondrial. Nke a na-egosi na MOTs-C na-echebe anụ ahụ mebiri emebi site na ichekwa mitochondria na ibelata apoptosis ^[5].

Nchedo nke mkpụrụ ndụ ndị ọzọ: N'ọmụmụ ihe na Duchenne muscular dystrophy (DMD), MOTs-C nwere ihe ndị na-eme ka uru ahụ dị n'ime. Ọ na-eme ka glycolytic flux na ike mmepụta ike na akwara dystrophic, na-enye aka n'ịrụ ọrụ muscle ka mma. Ọzọkwa, na ụdị mgbu na-egbuke egbuke, MOTs-C nke a na-elekọta ma ọ bụ n'akụkụ ya na-ebelata ihe mgbu na-egbuke egbuke site n'ịkwụsị nzaghachi mkpali na hyperexcitability neuronal, na-enye mmetụta neuroprotective ^[2,6]..

Kedu ihe bụ ngwa MOTS-C?

Ọgwụgwọ Ọrịa Metabolic:

Ịkwalite nguzogide insulin na igbochi metabolism: MOTS-C na-akwalite nguzogide insulin, nke dị mkpa maka igbochi ụdị 2 metabolism. Nguzogide insulin bụ isi ihe na-ebute mmalite nke ụdị 2 metabolism. MOTs-C nwere ike imeziwanye mmetụta insulin site na ịgbalite ụzọ akara AICAR-AMPK na ịhazi okirikiri folate-methionine intracellular. Nnyocha nke Gao Y na-egosi na ọ na-akwalite nnabata glucose n'ime akwara skeletal, dị ka imepe ụzọ nnabata glucose ọzọ na sel, si otú a na-ebelata ọkwa glucose ọbara ^[1]..

Na-achịkwa metabolism lipid na ịlụso oke ibu ọgụ: Banyere metabolism lipid, MOTs-C na-abawanye thermogenesis abụba agba aja aja ma na-akwalite agba aja aja na-acha ọcha. Abụba aja aja na-eri ike site na thermogenesis, ebe abụba na-acha ọcha na-egosi mgbanwe ike na-echekwa abụba ọcha ka ọ bụrụ abụba aja aja na-eri ike. Usoro a na-enyere ahụ aka ime mgbanwe na oyi na, nke ka mkpa, na-egbochi oke ibu na nsogbu metabolism lipid, na-enye nghọta ọhụrụ maka mgbochi na ọgwụgwọ oke ibu ^[1].

Mgbochi na ọgwụgwọ nke ọrịa metụtara akwara:

Ịkwalite Ịdịiche Muscle: Nnyocha ọmụmụ vitro na-egosi na ụdị anụ ọhịa MOTs-C peptide na-eme ka ọkpụkpụ myotubular dị na mmadụ (LHCN-M2) na òké (C2C12) mkpụrụ ndụ progenitor muscle, ebe Y8F mutant peptide enweghị mmetụta a. Nnyocha ndị ọzọ kpughere na MOTs-C na-eme ka myotubulogenesis dịkwuo mma site na iso ndị IL-6 / Janus kinase / transducer transducer na onye na-eme ihe na-eme ka ụzọ 3 (STAT3) transcription, si otú ahụ belata ọrụ STAT3 transcriptional ^[7].

Mgbochi nke Atrophy Muscle: Ọkwa Plasma MOTs-C na-emetụta ọkwa myostatin na-adịghị mma. MOTs-C na-egbochi atrophy myotube na-akpata palmitate na sel C2C12 dị iche iche ma na-ebelata ọkwa myostatin plasma na oke oke ibu na-ebute nri. Ọ na-egbochi atrophy anụ ahụ site na ịkwalite AKT phosphorylation, na-egbochi ọrụ FOXO1-ihe ntinye ederede nke myostatin na mkpụrụ ndụ akwara-atrophy ndị ọzọ-mgbe na-achịkwa mTORC2 na ọrụ PTEN na ịba ụba ọrụ CK2 iji kwụsị PTEN ^[8].

Mmetụta mgbochi ịka nká: Mgbanwe okwu MOTs-C nwere njikọ chiri anya na ịka nká, ọ na-egosipụtakwa ihe mgbochi ịka nká. A na-enweta nke a site n'ọtụtụ usoro, gụnyere imeziwanye glucose na metabolism lipid, na-eme ka ọrụ mitochondrial cellular dịkwuo elu, na ibelata mbufụt na-adịghị ala ala. Nnyocha nke Gao Y et al. na-egosi na metabolism ka mma na-enye mkpụrụ ndụ n'ụba ma kwụsie ike. Ịkwalite ọrụ mitochondrial yiri ịkwalite ụlọ ọrụ mmepụta ihe nke ume, ebe mbelata nzaghachi mkpali na-ebelata mmebi mkpali nke mkpụrụ ndụ ^[1].

Mmechi

Dị ka peptide sitere na mitochondrial, MOTs-C na-arụ ọrụ ụzọ mgbaàmà dị ka AMPK iji mezie glucose na lipid metabolism, na-akwalite mgbanwe abụba na-acha ọcha na agba aja aja, ma melite nguzogide insulin na oke ibu, na-enye ntụziaka ọgwụgwọ ọhụrụ maka nsogbu metabolic. Ọ na-eme ka ọdịiche osteoblast dịkwuo mma, na-egbochi nhazi osteoclast, na-edozi metabolism ọkpụkpụ, ma na-akwado nlekọta ahụike skeletal. Ọ na-achịkwa ọdịiche dị n'ahụ ahụ ma na-egbochi atrophy, na-ejide ikike itinye aka na nsogbu ndị metụtara akwara. MOTs-C na-egosiputa mkpakọrịta siri ike metụtara mmega ahụ: mmega ahụ na-edozi okwu ya, ọ na-edozikwa uru ahụike na-emega ahụ. MOTs-C na-ekerekwa òkè na igbu oge ịka nká na usoro ndị metụtara ya.
