EBINTU BYONNNA N’AMAWULIRE GW’EBINTU EBIweereddwa KU MUTINDO GUNO BIKOZESEBWA KU KUSASANYA AMAWULIRE N’EBIKOLWA BY’OKUSOMESA.
Ebintu ebiweereddwa ku mukutu guno bigendereddwamu kunoonyereza mu kisenge (in vitro research) byokka. Okunoonyereza mu vitro (Olulattini: *mu ndabirwamu*, ekitegeeza mu bikozesebwa mu ndabirwamu) kukolebwa ebweru w’omubiri gw’omuntu. Ebintu bino si bya ddagala, tebikkiriziddwa kitongole kya Amerika ekivunaanyizibwa ku by’emmere n’eddagala (FDA), era tebirina kukozesebwa kuziyiza, kujjanjaba oba kuwonya mbeera yonna ya bujjanjabi, bulwadde oba bulwadde. Kikugirwa nnyo mu mateeka okuyingiza ebintu bino mu mubiri gw’omuntu oba ebisolo mu ngeri yonna.
Okulambika okutwaliza awamu
Bam15, nga selective mitochondrial uncoupler, ebadde ekozesebwa mu kunoonyereza ku nkyukakyuka y’emmere mu myaka egiyise, ng’ewa obujjanjabi obupya ku ndwadde ez’enjawulo ez’enkyukakyuka mu mubiri. Mitochondria zikola kinene mu nkyukakyuka y’amasoboza g’obutoffaali, ezivunaanyizibwa ku kukola ATP okuyita mu oxidative phosphorylation, bwe kityo ne ziwa amaanyi eri emirimu egy’enjawulo egy’obutoffaali. Mu mbeera ezimu ez’obulwadde, enkola ya mitochondria eyinza okukosebwa, ekivaako obuzibu mu nkyukakyuka y’emmere era nga ekwatagana nnyo n’okutandika n’okukulaakulana kw’endwadde ng’omugejjo, ssukaali, n’obulwadde bw’ekibumba obw’amasavu obutali bwa mwenge.
Bam15 etunuulira nnyo mitochondria era, okuyita mu nkola ey’enjawulo ey’okukola, etaataaganya okuyungibwa okunywevu wakati w’entambula y’obusannyalazo n’okusengejja ATP. Kitumbula okudda emabega kwa pulotoni okuyita mu luwuzi lwa mitochondria olw’omunda, bwe kityo ne kisaasaanya ekiwujjo kya pulotoni, ne kisobozesa olujegere lw’okussa olwa mitochondrial okugenda mu maaso n’okukola naye nga kikendeeza ku bulungibwansi bw’okusengejja ATP. Ekikolwa kino eky’okukutula kirina amakulu amakulu mu mubiri, kubanga kitumbula okussa kw’emitochondria, kyongera okukozesa amaanyi, n’okusaasaanya amaanyi mu ngeri y’ebbugumu, bwe kityo ne kitereeza bbalansi y’okukyusakyusa amaanyi mu mubiri.
Ekifaananyi 1 Enkola y’okukutula kwa oxidative phosphorylation okuleetebwa BAM15.
Ebivaamu
Okutumbula enkyukakyuka y’amasoboza: Bam15 eyongera nnyo ku miwendo gy’enkyukakyuka y’amasoboza mu mubiri okuyita mu nkola z’okukutula amaanyi mu mitochondria. Mu mbeera z’omubiri eza bulijjo, enkyukakyuka y’amasoboza g’obutoffaali esigala mu mbeera etali nnywevu okusobola okuyimirizaawo emirimu gy’omubiri egya bulijjo. Omubiri bwe gunywa amaanyi agasukkiridde agatasobola kunywa mangu, amaanyi agasukkiridde gaterekebwa ng’amasavu ekivaako okugejja n’okugejja. Bam15 etaataaganya bbalansi eno ng’ekola ku kussa kw’emitochondria, okusobozesa ebitundu ebiri mu butoffaali okufuuka oxidized n’okuvunda amangu, bwe kityo n’eyongera ku nsaasaanya y’amasoboza n’okukendeeza ku kukuŋŋaanyizibwa kw’amasavu. Mu kugezesa ebisolo, ebibe ebyajjanjabwa ne Bam15 byalaga okweyongera kw’obuzito okunyigirizibwa ennyo ne wansi w’emmere erimu amasavu amangi, ekiraga bulungi omulimu gwa Bam15 mu kutumbula enkyukakyuka y’amaanyi.
Okulongoosa obuziyiza bwa insulini: Obuziyiza insulini y’emu ku nkola enkulu ez’obulwadde (pathophysiological mechanisms) ezisibukako okukula kwa sukaali ow’ekika eky’okubiri. Mu mbeera egumira insulini, okuwuliziganya kw’ebitundu by’omubiri ku insulini kukendeera, ne kiremesa insulin okutumbula obulungi okuyingiza n’okukozesa glucose, bwe kityo ne kivaako emiwendo gya glucose mu musaayi okulinnya. Bam15 esobola okulongoosa obuziyiza bwa insulini ng’ayita mu makubo agawerako. Kitumbula okukyusakyusa amaanyi, okukendeeza amasavu agasukkiridde okukuŋŋaanyizibwa mu bitundu by’omubiri naddala amasavu mu bitundu by’omubiri. Ebitundu by’amasavu ebisukkiridde bifulumya ebintu bingi ebizimba n’ebirungo ebiyitibwa adipokines, ebitaataaganya okutambuza okwa bulijjo okw’amakubo agalaga obubonero bwa insulini, ekivaako okuziyiza insulini. Oluvannyuma lw’okukendeeza ku kukuŋŋaanyizibwa kw’amasavu, Bam15 ekendeeza ku kuddamu kw’okuzimba, bwe kityo n’elongoosa enkola y’ekkubo ly’obubonero bwa insulini. Bam15 era esobola okukola butereevu ku molekyo z’obubonero bwa insulini mu butoffaali, okutumbula okutambuza obubonero bwa insulini n’okwongera okuwuliziganya kw’obutoffaali eri insulini, okusobozesa obutoffaali okutwala obulungi n’okukozesa glucose, bwe kityo ne kikendeeza ku mutindo gwa glucose mu musaayi.
Okutumbula mitochondrial autophagy: Mitochondrial autophagy nkola nkulu eri obutoffaali okukuuma omutindo gwa mitochondrial n’enkola y’emirimu. Mitochondria bwe zoonoonese oba nga tezikola bulungi, obutoffaali butandika enkola ya mitochondrial autophagy, ne busiba mitochondria eyonoonese ne buzitambuza mu lysosomes okusobola okuvunda okukuuma obulamu bw’ekibinja kya mitochondria munda mu katoffaali. Mu mbeera z’obulwadde ng’emmere erimu amasavu amangi, mitochondria zitera okwonooneka, ekivaako mitochondria obutakola bulungi n’okwongera okusajjula obuzibu mu nkyukakyuka y’emmere. Bam15 etumbula nnyo mitochondrial autophagy nga upregulating okwolesebwa mitochondrial autophagy marker genes Pink1 ne Parkin, okuleetera obutoffaali okugogola amangu mitochondria eyonoonese, okulongoosa mitochondria omutindo okufuga, okuzzaawo normal mitochondrial enkola, n’okukuuma cellular energy metabolic homeostasis.
Okulungamya enkyukakyuka y’amasavu: Bam15 ekola kinene nnyo mu kulungamya enkyukakyuka y’amasavu. Kitumbula lipolysis mu hepatocytes, kiziyiza lipid synthesis, era kikendeeza lipid okukuŋŋaanyizibwa mu kibumba. Mu mbeera z’obulwadde nga hyperlipidemia, emiwendo gy’amasavu egy’amaanyi mu musaayi givaako okukuŋŋaanyizibwa kw’amasavu okuyitiridde mu bitundu ng’ekibumba, ekivaako endwadde ezikwatagana n’amasavu nga steatosis. Bam15 ekyusa emirimu gy’enziyiza ezenyigira mu nkyukakyuka y’amasavu, gamba ng’okutumbula okwolesebwa kw’enziyiza ezikwatagana n’okuziyiza asidi w’amasavu n’okuziyiza emirimu gy’enziyiza z’okusengejja asidi z’amasavu, bwe kityo n’eyongera ku oxidation n’okuvunda kwa asidi w’amasavu ate nga kikendeeza ku kusengejja. Kino kikendeeza ku muwendo gw’amasavu mu kibumba n’omusaayi, ne kitereeza obuzibu mu nkyukakyuka y’amasavu.
Okusaba
Obujjanjabi bw’omugejjo: Omugejjo gufuuse ensonga y’ebyobulamu mu nsi yonna era gukwatagana nnyo n’okutandika kw’endwadde ez’enjawulo ezitawona. Olw’obusobozi bwayo okutumbula enkyukakyuka y’amaanyi n’okukendeeza ku kukuŋŋaanyizibwa kw’amasavu, Bam15 eraga obusobozi bungi mu kujjanjaba omugejjo. Ebyavudde mu kugezesa ebisolo biraga nti ebibe ebinene ennyo ebyajjanjabwa ne Bam15 byakendeera nnyo mu buzito, omubiri gwalongooka, amasavu ne gakendeera, n’ebinywa ebigonvu byeyongera nnyo. Bwe kityo, Bam15 esobola okukola ng’ekirungo ekiyinza okujjanjaba obujjanjabi bw’omugejjo ng’etereeza bbalansi y’amaanyi, okuyamba okugejja mu balwadde abagejjulukuka, n’okukendeeza ku bulabe bw’ebizibu ebiva ku mugejjo.
Obujjanjabi bwa sukaali: Okusinziira ku mulimu omukulu Bam15 gw’erina mu kulongoosa obuziyiza bwa insulini n’okutereeza emiwendo gya glucose mu musaayi, efunye okufaayo okunene mu bujjanjabi bwa sukaali. Okunoonyereza nga tekunnabaawo kulaga nti Bam15 esobola okutumbula okuwuliziganya kwa insulini mu bikolwa by’ebisolo ebirina ssukaali, okukendeeza ku glucose mu musaayi, n’okulongoosa okugumira glucose okukosebwa. Kino kiwa enkola empya n’eddagala eriyinza okukozesebwa mu kujjanjaba ssukaali. Bw’ogeraageranya n’eddagala lya sukaali ery’ekinnansi, Bam15 etereeza enkyukakyuka mu mubiri ng’eyita mu nkola ey’enjawulo, n’efuga bulungi emiwendo gya glucose mu musaayi awatali kuleeta bizibu bya maanyi nga okukendeera kwa sukaali, bwe kityo n’ewa obujjanjabi obulungi eri abalwadde ba ssukaali.
Obujjanjabi bw’obulwadde bw’ekibumba obw’amasavu obutali bwa mwenge: Obulwadde bw’ekibumba obutali bwa masavu bulwadde bwa kibumba obutera okubeera mu nkyukakyuka y’emmere obumanyiddwa ng’amasavu agasukkiridde okukuŋŋaanyizibwa mu kibumba. Bam15 esobola bulungi okukendeeza ku hepatic steatosis n’okulongoosa enkola y’ekibumba nga etereeza lipid metabolism n’okutumbula mitochondrial autophagy. Mu kugezesa ebisolo, ebisolo eby’ekyokulabirako eby’obulwadde bw’ekibumba eby’amasavu ebitali bya mwenge ebyajjanjabwa ne Bam15 byalaga okukendeera okw’amaanyi mu masavu mu kibumba n’okulongoosa obubonero bw’enkola y’ekibumba.
Okubumbako
Bam15 etunuulidde enkyukakyuka y’omubiri mu mitochondria, ng’ekola kinene mu nkola enkulu ng’obutakwatagana na maanyi, okuziyiza insulini, obuzibu bw’amasavu, n’okulondoola omutindo gwa mitochondria, bwe kityo n’ewa enkola empya ez’obujjanjabi ku ndwadde z’enkyukakyuka mu mubiri ng’omugejjo, ssukaali, n’obulwadde bw’ekibumba obw’amasavu, awamu n’ebizibu ebikwatagana nabyo.
