Ensibuko y’okunoonyereza eya Motc eri etya?

Mitochondria, ezikola nga 'powerhouse' y'obutoffaali, zikola kinene nnyo mu kukuuma homeostasis y'obutoffaali. Enkola z’empuliziganya wakati wa mitochondria ne nucleus zibadde zisinga kutunuulirwa mu kunoonyereza kwa ssaayansi okuva edda. Mitochondria zirina ensengekera y’obutonde (genome) eyetongodde. Okusukka obuzaale 37 obwa kalasi, okunoonyereza okwakakolebwa kulaga nti DNA ya mitochondrial nayo ekola enkodi ya peptides ennyimpi ezikola mu biramu, emu ku zo ye peptide evudde mu mitochondrial Motc, ewandiikiddwa ekitundu kya mitochondrial 12S rRNA. Okuzuula kuno kugaziya nnyo obuwanvu bw’obuzaale bwa mitochondrial, nga kuwa endowooza empya ey’okunnyonnyola enkola z’ebiramu ezikulu nga empuliziganya ya mitochondrial-nuclear n’okulungamya metabolic.

Mu kiseera kino, obujjanjabi bw’endwadde nnyingi ezisomooza nga metabolism ne chronic hepatitis B bwolekagana n’ebizibu ebinene. Omulimu omukulu Motc gwe yakola mu kulungamya enkyukakyuka y’ebinywa by’amagumba, gamba ng’okutumbula enkyukakyuka ya glucose, gulaga obusobozi bwayo mu kujjanjaba obuzibu mu nkyukakyuka y’emmere. Ekirala, emiwendo gya Motc egitaali gya bulijjo egyalabibwa mu nkola z’endwadde ez’enjawulo gireetedde abanoonyereza okunoonyereza ku kifo kyayo mu kutandika kw’obulwadde, okukula, n’okubujjanjaba, nga banoonya amakubo amapya ag’okuvvuunuka embeera zino ezitasobola kugonjoolwa.

Enkola y’okukola eri Motc eri etya?

Okulungamya Amakubo g’obubonero agakwatagana n’enkyukakyuka y’ebirungo

Okukola ekkubo ly’obubonero bwa AICAR-AMPK: Motc ekola ekkubo ly’obubonero bwa AICAR-AMPK nga etaataaganya enzirukanya ya folate-methionine mu butoffaali. AMPK ekola etereeza enkyukakyuka y’amasoboza g’obutoffaali, gamba ng’okutumbula okutwalibwa kwa glucose n’okukyusa asidi w’amasavu. Mu nkyukakyuka ya glucose, kyongera okutambuza ekitambuza glucose GLUT4 okudda mu luwuzi lw’obutoffaali, bwe kityo ne kyongera ku busobozi bw’obutoffaali okutwala glucose, okulongoosa obuziyiza bwa insulini, n’okuyamba mu kuziyiza n’okujjanjaba endwadde z’enkyukakyuka mu mubiri nga enkyukakyuka y’omubiri ey’ekika eky’okubiri ^[1]..

Ebikosa amakubo amalala: Okusukka ekkubo lya AMPK, Motc era ekola ku kkubo lya AKT, ekkubo lya oxidative stress, n’amakubo agakwatagana n’okuzimba. Ku bikwata ku kkubo lya AKT, liyinza okukwata ku nkola z’obutoffaali nga okukula, okukula, n’okuwangaala nga lifuga emirimu gy’ekkubo. Mu kkubo ly’okunyigirizibwa okw’okwokya, Motc ekendeeza ku miwendo gy’okunyigirizibwa okw’okwokya mu butoffaali, ekendeeza ku kukola ebika bya okisigyeni ebikola (ROS), era ekuuma obutoffaali okuva mu kwonooneka kw’okwokya. Mu makubo agakwatagana n’okuzimba, kiziyiza okufuluma kw’abatabaganya okuzimba era kikendeeza ku kuddamu kw’okuzimba. Okugeza, mu bikolwa by’obulumi bw’okuzimba, Motc ekendeeza ku kufulumya kw’omutabaganya w’okuzimba mu jjembe ly’omugongo, bwe kityo n’etereeza obubonero bw’obulumi ^[2]..

Ekifaananyi 1 Emirimu emikulu egy’omubiri gwa Motc mulimu okukendeeza ku buziyiza bwa insulini, okuziyiza omugejjo, okulongoosa enkola y’ebinywa, okutumbula enkyukakyuka y’amagumba, okutumbula enkola y’abaserikale b’omubiri, n’okulwawo okukaddiwa ^[1]..

Okulungamya Okwolesebwa kw’Obuzaale

Okulungamya okwolesebwa kw’obuzaale bwa nyukiliya: Obutoffaali bwe busisinkana okunyigirizibwa kw’enkyukakyuka mu mubiri, gamba ng’okuziyiza glucose n’okunyigirizibwa okw’okwokya, Motc ekyuka n’egenda mu nyukiliya okulung’amya butereevu okwolesebwa kw’obuzaale bwa nyukiliya obukwatagana, bwe kityo n’etumbula homeostasis mu butoffaali. Okugeza, Motc ekyusakyusa okwolesebwa kw’obuzaale obukwatagana n’enkyukakyuka y’emmere nga GLUT4, STAT3, ne IL-10, n’ekwata ku nkola z’omubiri omuli enkyukakyuka ya glucose n’okulungamya abaserikale b’omubiri. Okwongera mu kwolesebwa kwa GLUT4 kwongera ku kutwalibwa kwa glucose mu butoffaali; STAT3 yeetaba mu kukula kw’obutoffaali, okwawukana, n’okulungamya abaserikale b’omubiri; IL-10, ekirungo ekiziyiza okuzimba, kikendeeza ku kuddamu kw’okuzimba nga okwolesebwa kwayo kuli waggulu ^[1,3]..

Okwongera ku nkyukakyuka y’amasoboza

Enhanced Glycolysis: Mu bikolwa by’endwadde ez’enjawulo, nga enkola y’obuvune bw’amawuggwe-reperfusion injury (LIRI) evudde ku cardiopulmonary bypass (CPB), Motc pretreatment eyongera ku glycolytic flux mu pulmonary microvascular endothelial cells (PMVECs). Kikendeeza ku buvune bwa LIRI nga kizzaawo homeostasis y’amaanyi g’obutoffaali n’okukendeeza ku lipid peroxidation okuyita mu upregulating key glycolytic enzyme PFKFB3. Kino kiraga nti Motc ekyusa ekkubo lya glycolytic okusobola okuwa amaanyi agamala eri obutoffaali wansi w’okunyigirizibwa, bwe kityo n’ekuuma enkola y’obutoffaali eya bulijjo ^[4]..

Ebiva mu Kukuuma Obutoffaali

Okukendeeza ku kwonooneka kw’obutoffaali bw’omubiri (mitochondrial Damage): Mu nkola ya radiation pneumonitis (RP), Motc yakendeeza nnyo ku buvune bw’ebitundu by’amawuggwe, okuzimba, n’okunyigirizibwa okw’okwokya ate ng’ezzaawo apoptosis y’obutoffaali bw’omubiri (alveolar epithelial cell apoptosis) n’okwonooneka kw’obutoffaali bw’omubiri (mitochondrial damage). Enkola eno erimu okwongera ku miwendo gya nuclear factor E2-related factor 2 (Nrf2) n’okutumbula enkyukakyuka yaayo eya nuclear. Nrf2 ekola omuddirirwa gw’obuzaale obuziyiza obuwuka obuleeta obulwadde n’okukuuma obutoffaali, okukuuma enkola ya mitochondria. Kino kiraga nti Motc ekuuma ebitundu ebyonooneddwa nga ekuuma mitochondria n’okukendeeza ku apoptosis ^[5]..

Okukuuma Obutoffaali Obulala: Mu kunoonyereza ku bulwadde bwa Duchenne muscular dystrophy (DMD), Motc yazuulibwa ng’erina eby’obugagga ebigenderera ebinywa eby’omunda. Kyongera ku glycolytic flux n’obusobozi bw’okufulumya amaanyi mu binywa ebizibu, ekiyamba okulongoosa enkola y’ebinywa. Ate era, mu bikolwa by’obulumi bw’okuzimba, Motc eweebwa wakati oba ku bbali ekendeeza ku bulumi obuyitiridde nga eziyiza okuddamu kw’okuzimba n’okucamuka ennyo kw’obusimu, n’ewaayo ebikolwa eby’okukuuma obusimu ^[2,6]..

Enkola za Motc ze ziruwa?

Obujjanjabi bw’obuzibu bw’enkyukakyuka mu mubiri:

Okulongoosa obuziyiza bwa insulini n’okuziyiza enkyukakyuka mu mubiri: Motc eyongera ku buziyiza bwa insulini, ekintu ekikulu ennyo mu kuziyiza enkyukakyuka y’omubiri ey’ekika eky’okubiri. Okuziyiza insulini nsonga nkulu mu kutandika kw’enkyukakyuka y’emmere ey’ekika eky’okubiri. Motc eyinza okulongoosa okuwuliziganya kwa insulini ng’ekola ekkubo ly’obubonero erya AICAR-AMPK n’okulungamya enzirukanya ya folate-methionine mu butoffaali. Okunoonyereza okwakolebwa Gao Y kulaga nti kitumbula okutwala n’okukozesa glucose mu binywa by’amagumba, okufaananako okuggulawo amakubo amalala ag’okunyiga glucose mu butoffaali, bwe kityo ne kikendeeza ku glucose mu musaayi ^[1]..

Okulungamya enkyukakyuka y’amasavu n’okulwanyisa omugejjo: Ku bikwata ku nkyukakyuka y’amasavu, Motc ayongera ku thermogenesis y’amasavu aga kitaka n’okutumbula okufuuka kw’amasavu amazungu. Amasavu ga kitaka ganywa amaanyi nga gayita mu thermogenesis, ate amasavu amazungu aga browning kitegeeza okukyusa amasavu amazungu agatereka amaanyi ne gafuuka amasavu ga kitaka aganywa amaanyi. Enkola eno eyamba omubiri okumanyiira embeera y’obunnyogovu era ekisinga obukulu, eziyiza omugejjo n’obuzibu mu nkyukakyuka y’amasavu, n’ewa amagezi amapya ku kuziyiza n’okujjanjaba omugejjo ^[1]..

Okuziyiza n’okujjanjaba endwadde ezeekuusa ku binywa:

Okutumbula enjawulo mu binywa: Okunoonyereza mu vitro kulaga nti peptide ya Motc ey’ekika ky’omu nsiko eyongera ku kutondebwa kwa myotubular mu butoffaali bwa jjajja w’ebinywa by’omuntu (LHCN-M2) n’eby’ebibe (C2C12), so nga peptide eya Y8F mutant terina kikolwa kino. Okunoonyereza okulala kwalaga nti Motc eyongera ku myotubulogenesis nga ekwatagana n’ekkubo lya IL-6/Janus kinase/signal transducer ne activator of transcription 3 (STAT3), bwe kityo ne kikendeeza ku STAT3 transcriptional activity ^[7]..

Okuziyiza okuzimba ebinywa: Emiwendo gya Motc mu plasma gikwatagana bubi n’emiwendo gya myostatin. Motc eziyiza palmitate-induced myotube atrophy mu differentiated C2C12 cells era ekendeeza ku plasma myostatin levels mu mbeba omugejjo induced endya. Kiziyiza okukendeera kw’ebinywa nga kyongera ku AKT phosphorylation, okuziyiza emirimu gya FOXO1 —ensonga y’okuwandiika waggulu eya myostatin n’obuzaale obulala obw’okukendeera kw’ebinywa —ate nga kitereeza emirimu gya mTORC2 ne PTEN n’okwongera ku mirimu gya CK2 okunyigiriza PTEN ^[8]..

Ebikolwa ebiziyiza okukaddiwa: Enkyukakyuka mu kwolesebwa kwa Motc zikwatagana nnyo n’okukaddiwa, era eraga eby’obugagga ebiziyiza okukaddiwa. Kino kituukibwako okuyita mu nkola eziwera, omuli okulongoosa enkyukakyuka ya glucose ne lipid, okutumbula enkola ya mitochondrial y’obutoffaali, n’okukendeeza ku kuzimba okutambula obutawona mu nkola. Okunoonyereza okwakolebwa Gao Y et al. kiraga nti okulongoosa mu nkyukakyuka y’emmere kiwa obutoffaali amaanyi amangi era agatebenkedde. Okwongera ku nkola ya mitochondria kifaananako n'okulongoosa 'ekkolero ly'amaanyi,' ly'obutoffaali ate okukendeeza ku kuddamu kw'okuzimba kikendeeza ku kwonooneka kw'okuzimba kw'obutoffaali ^{[1] .}.

Mu bufunzi

Nga peptide evudde mu mitochondrial, Motc ekola amakubo g’obubonero nga AMPK okulungamya enkyukakyuka ya glucose n’amasavu, okutumbula okukyusa amasavu amazungu okudda mu kitaka, n’okulongoosa okuziyiza insulini n’omugejjo, nga kiwa endagiriro empya ez’obujjanjabi eri obuzibu mu nkyukakyuka y’emmere. Kyongera ku njawulo y’amagumba, kinyigiriza okutondebwa kw’amagumba, kitebenkeza enkyukakyuka y’amagumba, era kiwagira okukuuma obulamu bw’amagumba. Kitereeza enjawulo y’ebinywa n’okuziyiza okuzimba, nga kikwata obusobozi bw’okuyingira mu nsonga mu buzibu obukwatagana n’ebinywa. Motc eraga enkolagana ey’amaanyi ekwatagana n’okukola dduyiro: dduyiro upregulates okwolesebwa kwayo, era atabaganya emigaso gy’obulamu egy’okukola dduyiro. Motc era ekola kinene mu kulwawo okukaddiwa n’enkola ezikwatagana nabyo.
