Emize gyaffe giyinza n’okukyusa obuzaale bwaffe? Ka tuyige ku epigenetics mu ngeri ennyangu!

Oboolyawo owulidde nti obuzaale bwaffe bwe bukwata ku ngeri gye tulwala n’engeri gye tulabika. Ekyo kituufu. Naye obadde okimanyi nti era tusobola okukyusa engeri obuzaale buno gye bukolamu nga tuyita mu bintu ng’obulamu bwaffe, bye tulya, n’obutonde bwe tubeera? Ebyo bye bintu bye twogerako wansi w'omulamwa guno oguyitibwa Epigenetics . Wadde nga guno mulamwa mupya nnyo, mukulu nnyo eri obulamu bwaffe, kale katugwogereko.

Kale kino ddala (Epigenetics) kye ki?

Mu ngeri ennyangu, epigenetics kwe kunoonyereza ku ngeri obuzaale bwaffe gye bukosebwamu obutonde bwaffe n’ebintu bye tukola . Tutera okulowooza ku buzaale ng’ekintu kye tutasobola kufuga, kye tusikira okuva mu bazadde baffe. Mu butuufu, ebintu bingi, gamba ng’embala y’amaaso gaffe n’emikisa gy’okufuna endwadde ezimu, bisalibwawo obuzaale buno okuva lwe tuzaalibwa. Kale oyinza okulowooza nti obuzaale kintu ekitasobola kukyusibwa, ekiteekebwa mu mayinja. Naye teebereza singa tusobola okukyusa engeri obuzaale buno gye bukolamu netulongoosa obulamu bwaffe ? Bannasayansi banoonyereza ku epigenetics nga balina essuubi eryo mu birowoozo. Eno y’ensonga lwaki omulamwa guno, epigenetics, gufuuse ekintu abantu bangi nga ggwe kye baagala okuyiga. Epigenetics kitundu kipya nnyo eky’okunoonyereza. Kitunuulira engeri eddagala erimu eriri mu butoffaali bw’omubiri gwaffe gye lifuga engeri obuzaale bwaffe gye bukolamu. Bannasayansi eddagala lino bayita ‘epigenetic marks’ oba ‘chemical signatures’ . Oluusi obubonero buno obw’eddagala buyamba emibiri gyaffe okubeera egy’amaanyi n’okugumira endwadde. Naye oluusi biyinza okukosa obulamu bwaffe. Bw’omenya ekigambo ‘epigenetics’, waliwo ebitundu bibiri: ‘epi’ ne ‘genetics’. ‘Epi’ Luyonaani ekitegeeza ‘waggulu, ebweru, okwetooloola’. ‘Genetics’ ekwata ku buzaale, kwe kugamba, enkumi n’enkumi z’ebitundu bya DNA (Deoxyribonucleic Acid) ebikufuula ow’enjawulo. Kale, bwe twogera ku ‘epigenetics’, tuba twogera ku buli kimu ekyetoolodde obuzaale bwo. Bannasayansi batunuulidde eddagala erituula ddala ku buzaale bwo ne likola ku zo. Era bafaayo ku bintu bye tusobola okwetegereza mu bulamu bwaffe obwa bulijjo, gamba ng’emmere gye tulya, dduyiro gye tukola, n’okulabirira kwe twafuna nga tukyali bato.

Obutonde bwaffe n’ebyo bye tusalawo bikwata bitya ku kino?

Bannasayansi baludde nga bakimanyi nti embeera gye tubeera n’enneeyisa yaffe ku bubwe bye bikola obulamu bwaffe. Ng’ekyokulabirako, lowooza ku:

• Okukwatibwa obutwa obumu kyongera obulabe bw'okufuna kookolo .
• Obujama bw'empewo busobola okuleeta endwadde nga asima .
• Dduyiro anyweza omutima gwo .
• Okulya emmere erimu ebiriisa kirungi nnyo eri obwongo n'omubiri gwo .

Kale, obulamu bwo n’okuwangaala kwo tebiva ku buzaale bwo oba butonde bwo bwokka. Waliwo ebintu ebirala bingi ebikosa kino, okitegedde?

Ka tusooke tuyige katono ku buzaale ne DNA, nedda?

Ensengekera z’obuzaale ze yuniti enkulu eza DNA. Omutendera gwo gwonna ogwa DNA gutera okugeraageranyizibwa ku kitabo ky’ensuku oba ekitabo ekikwata ku biragiro. Ekyo kiri bwe kityo kubanga DNA y’ewa ebiragiro buli katoffaali mu mubiri gwo bye bwetaaga okukola obulungi. Obutoffaali bwo busoma DNA eno okumanya eky’okukola n’engeri y’okukikola.

Olwo obuzaale kye ki?

Mu mubiri gwo mulimu obuwumbi n’obuwumbi bw’obutoffaali mu kiseera kyonna. Obutoffaali buno buli kiseera buba bwawukana okukola obutoffaali obupya (okwekolera kkopi) okudda mu kifo ky’obwo obufa. Ekyo kiri bwe kityo kubanga obutoffaali bwe bumu tebulina kumala bulamu bwo bwonna - bufa, era obupya ne bukolebwa. Eno nkola ya bulijjo mu mubiri gwo. Obuwumbi buno obw’obutoffaali bwesigamye ku DNA yo okumanya engeri gy’olina okukula, ddi lw’olina okukola kkopi, ne ddi lw’olina okulekera awo okugabanyaamu.

Obutoffaali bukozesa butya DNA eno?

Buli katoffaali mu mubiri kakola omulimu gwako. Ekyo okukikola, basoma ebitundu ebitongole ebya DNA yo. Ebitundu ebyo biyitibwa obuzaale bwo ssekinnoomu. Osobola okulowooza ku buzaale buno ng’essuula mu kitabo ky’ebiragiro, oba ng’enkola y’emmere mu kitabo ky’okufumba. Ensengekera z’obuzaale ze butundutundu obutonotono obw’amawulire obukwatagana ne bukola ekibinja kyo kyonna eky’obuzaale oba ensengekera y’obuzaale . Naye si buli katoffaali nti kasoma ebiragiro byonna (omutendera gwo gwonna ogwa DNA, oba genome). Ekyo kiri bwe kityo kubanga si buli katoffaali nti yeetaaga ebiragiro byonna - byetaaga ebitundu ebimu byokka. Obutoffaali bulina emirimu egy’enjawulo mu mubiri, era bwetaaga okukola emirimu gyabwo egy’enjawulo. Lowooza ku kino: bw’oba ​​okola keeki, teweetaaga nkola ya ssoosi y’ennyaanya. Omala kwetaaga recipe y'ebyo by'okola.

Kale epigenome eno kye ki?

Epigenome yo yonna ye genes zo ne buli kimu ekifuga engeri gy'ozikozesaamu . Ekikulu kiri nti epigenome yo ekyukakyuka . Kikyuka okumala ekiseera. Kino kiyinza okuba ekirungi oba ekibi. Kirungi kubanga ebintu ng’emmere erimu ebiriisa, dduyiro, n’okubeera mu situleesi ey’ekigero bisobola okuvaako enkyukakyuka mu nsengekera y’obutonde (epigenetic changes) eziyamba obulamu. Naye ebintu ng’emmere erongooseddwa, okunywa sigala, n’okunyigirizibwa okuyitiridde bisobola okuvaako enkyukakyuka mu nsengekera y’obutonde (epigenetic changes) ez’obulabe eri obulamu. Kale, kiki ekikosa epigenome yo? Kiki ky’oyinza okukola ku nsonga eyo? Mu butuufu waliwo bingi bye tutamanyi. Naye obujulizi bulaga nti ebintu bye tuteeka mu mibiri gyaffe n’engeri gye tukwataganamu n’ensi etwetoolodde bisobola okukosa ennyo epigenome yaffe.Wadde nga bulijjo tetusobola kufuga bintu bino, oluusi tusobola okubiddukanya - ekyo kirungi nnyo okusinga bye tuyinza okwogera ku buzaale bwe tusikira, nedda?

Endwadde ki ezikwatagana ne epigenetics?

Bannasayansi bakyanoonyereza ku ngeri enkyukakyuka z’obuzaale (epigenetic changes) gye zikwata ku mibiri gyaffe n’okukula kw’endwadde. Era balowooza nti enkyukakyuka ezimu mu mubiri n’embeera z’obulwadde nabyo bisobola okuleeta enkyukakyuka mu epigenome yo. Okunoonyereza okwakakolebwa kulaga nti enkyukakyuka mu buzaale (epigenetic changes) zikwatagana ne:

• Engeri enkola y’omubiri gwo gy’ekola.
• Enkola y'okukaddiwa n'endwadde ezikwatagana n'okukaddiwa .
• Endwadde ezikwata obwongo bwo, gamba ng’obulwadde bwa Parkinson , Alzheimer’s disease , n’obulwadde obuleeta obulemu ku magezi .
• Okufuna kookolo .
• Obuzibu mu kukozesa ebiragalalagala .
• Okuzimba n'embeera ezikwatagana nabyo nga asima n'endwadde z'abaserikale b'omubiri .

Nga okunoonyereza bwe kugenda mu maaso, bannassaayansi basuubira nti:

• Funa okutegeera okupya ku ngeri enkyukakyuka z’obuzaale (epigenetic changes) gye zireeta oba gye zikwataganamu n’embeera z’endwadde ez’enjawulo.
• Manya kye tuyinza okukola mu bulamu bwaffe obwa bulijjo okukendeeza ku bulabe bw’endwadde ezimu.
• Okukola obujjanjabi obupya obw’endwadde obugenderera epigenome.

Mu butuufu kiki ekiyinza okukyusa epigenome yaffe?

Epigenome yo ekolebwa amaanyi agatabalika. Abamu batandika okukufuga nga tonnazaalibwa. Wano waliwo ebyokulabirako ebitonotono:

• Emmere maama wo gye yalya ng’akusitula mu lubuto lwe (pregnancy diet) .
• Obulamu bwa maama wo okutwaliza awamu n'obulamu obulungi obw'omutwe ng'ali lubuto .
• Endya gye wafuna ng'omwana omuwere n'omwana omuto .
• Ebizibu ebibaawo mu buto .
• Ebintu bye wayiga bye walina ng'omwana omuto n'enkolagana gye walina n'abantu abakulu .
• Okukwatibwa obutwa ng’obucaafu bw’empewo, omukka gwa dizero, n’omukka gwa sigala .
• Okukwatibwa eddagala nga obuveera, BPA, n’ebyuma ebizito nga lead oba cadmium.
• Okukozesa eddagala erimu eriwandiikiddwa omusawo .
• Okukozesa omwenge, taaba n’ebiragalalagala ebirala eby’okwesanyusaamu .
• Emmere gy'olya ng'omuntu omukulu .
• Omutendera gwo ogw'okukola emirimu gy'omubiri .
• Omutindo gwa situleesi mu bulamu bwo obwa bulijjo .
• Enkolagana yo n'enkolagana yo n'abantu .
• Ekitundu ky’obeera n’obuwagizi bw’ofuna (oba bw’otofuna) okuva mu kyo .
• Okufuna empeereza y'ebyobulamu n'ebikozesebwa okuwagira ebyetaago byo eby'obulamu .

Enkyukakyuka zino zibaawo zitya?

Bannasayansi bakyagenda mu maaso n’okuzuula engeri bino ebibikkulwa n’ebyo by’oyitamu gye bireeta enkyukakyuka mu butoffaali bwo. Okutwalira awamu, ensonga zino zikola obubonero bw’obuzaale ku DNA yo, obukosa engeri obutoffaali bwo gye bukolamu. Ng’ekyokulabirako, obubonero obulaga obuzaale (epigenetic marks) busobola okulemesa obutoffaali okusoma ebitundu ebimu eby’ensengekera y’obutonde (genome) yo. Kwe kugamba, obuzaale obuteeberezebwa okuba nga bukola busirisibwa, oba okuggyibwako. N’ekyavaamu, obutoffaali bwo tebusobola kusoma buzaale obwo (enkola z’emmere), era tebusobola kukola bimu ku bintu bye byetaaga okukukuuma ng’oli mulamu bulungi, gamba ng’okukomya obutoffaali bwa kookolo okukula. Enkyukakyuka ezimu ez’obulabe mu nsengekera y’obutonde (epigenetic changes) za kiseera kitono era zisobola okukyusibwa. Naye ebirala biwangaala, oluusi obulamu bwonna.

Enkyukakyuka zino zisobola okuba ez’obulungi?

Yee, ddala. Obubonero bwa epigenetic busobola okuba obw’omugaso, oba n’okukuuma. Ng’ekyokulabirako, okuwa omwana emikisa mingi okuyiga kiyinza okuvaamu enkyukakyuka ennungi mu nsengekera y’obutonde (epigenetic changes) eziyamba obulamu bwe obw’omutwe n’omubiri okumala emyaka egijja . Tosobola kulonda buzaale bw’osikira okuva mu bazadde bo. Era tosobola kufuga bingi ku nsi ekubeetoolodde. Naye okubeera ng’omanyi ensonga zino zonna ‘ezikuliisa’ - n’abaana bo - kiyinza okukuyamba okukola kyonna ky’osobola okukola epigenome ennungi.

Tusobola okufuga obulungi epigenome yaffe? Yee! Tya?

Yee, mazima ddala kisobola. Wadde nga tewali nteekateeka emu enkakafu ku ngeri y’okukikola, bannassaayansi balowooza nti ebimu ku bye tusalawo bisobola okuwagira enkyukakyuka ennungi mu nsengekera y’obutonde (positive epigenetic changes) n’okukendeeza ku bulabe bw’enkyukakyuka embi. Wano waliwo obukodyo bw’oyinza okuyamba:

• Lya emmere erimu ebiriisa. Osobola okunoonya obuyambi okuva eri omukugu mu by’endya okukola enteekateeka y’emmere etuukana n’ebyetaago byo eby’obulamu n’engeri gy’obeera.
• Ku lunaku lwo yongerako okukola emirimu gy’omubiri.Nga tonnatandika nteekateeka mpya ya dduyiro, kakasa nti oyogera n’omusawo wo. Bajja kukubuulira dduyiro ki ataliiko bulabe gy’oli.
• Komya omwenge era olekere ddala okukozesa ebintu ebikolebwa mu taaba.
• Fuba okuwummulamu nga bwe kisoboka okusobola okuddukanya situleesi.

Bino byonna by’osobola okwekolera. Kyokka, okunoonyereza kulaga nti epigenome yaffe esinga kukyuka mu myaka mitono egisooka egy’obulamu . Kale, bw’oba ​​oli muzadde oba omulabirira, kikulu nnyo okufaayo ku bintu bino:

• Kakasa nti omwana wo afuna emmere entuufu. Osobola okusaba omusawo w’abaana akuwe amagezi ku ngeri y’okukola kino.
• Omwana wo muwe emikisa okuyiga okuva mu buto. Kino kiyinza okuzingiramu okubawa eby’okuzannyisa ebibayamba okuyiga n’okujjukira, okwogera nabo, okusoma ebitabo, n’okubayigiriza ebigambo ebipya.
• Tonda embeera okwetooloola omwana wo mw’awulira bulungi, nga talina bulabe, era nga yeetooloddwa abantu abaagalana era abamuwagira.
• Bw’oba ​​oyolekedde okusoomoozebwa ng’obutaba na mmere, obutaba na mayumba, oba okutulugunyizibwa mu maka, noonya obuyambi okuva eri omusawo. Bayinza okukuyamba okufuna eby’obugagga by’olina okwekuuma n’abaana bo n’okufuna obuyambi.

N’ekisembayo, ebintu bye tulina okujjukira (Take-Home Message) .

Singa endowooza ya epigenetics ekuwulikika nga eyeewuunyisa era nga ekutiisa katono, si ggwe wekka. Okulowooza ku bigenda mu maaso munda mu mibiri gyaffe kiyinza okutusanyusa ate oluusi ne kituzitoowerera. Era kiyinza okuwulira nga tetulina kye tusobola kukola era nga tetulina maanyi. Kiwulira ng’ebintu bingi nnyo bivudde mu buyinza bwaffe. Naye epigenetics etuwa essuubi nti tusobola okuba n'obuyinza ku nkola ez'omunda ez'emibiri gyaffe .

Epigenetics ekyali mpya nnyo bw’ogeraageranya n’ebitundu ebirala eby’okunoonyereza. Wakyaliwo bingi bye tutamanyi. Naye ekyo kitegeeza nti waliwo bingi nnyo eby’okuzuula! Omusawo asobola okukubuulira ebisingawo ku ngeri obuzaale bwo n’epigenome gye bikosaamu obulamu bwo. Asobola n’okukubuulira w’oyinza okufuna ebisingawo.

Kale, mu ngeri ennyangu, obuzaale bwaffe kitundu kimu kyokka ku mboozi yaffe. Engeri gye tubeera, okusalawo kwe tukola, okwagala n’okufaayo kwe tufuna, byonna birina kinene nnyo kye bikola ku ngeri emboozi eyo gy’ewandiikibwamu. Ekyo kye ssomo erisinga okuba ery’omuwendo epigenetics lye etuyigiriza.
