Epigenetics: Borokho bo Pakeng tsa Liphatsa tsa Lefutso le Tikoloho
E 'ngoe ea mekhoa ea bohlokoa eo tikoloho e susumetsang tlhahiso ea liphatsa tsa lefutso ka eona ke ka epigenetics. Epigenetics e bolela liphetoho tse futsitsoeng tlhahisong ea liphatsa tsa lefutso tse sa akarelletseng liphetoho tatellanong ea DNA ea motheo. Liphetoho tsena li ka susumetsoa ke mabaka a fapaneng a tikoloho 'me li ka ama tsela eo liphatsa tsa lefutso li buloang kapa li timang ka eona.
DNA Methylation
Methylation ea DNA ke mokhoa oa mantlha oa epigenetic moo lihlopha tsa methyl li eketsoang molek'huleng ea DNA, hangata metheong ea cytosine. Maemo a phahameng a methylation ea DNA libakeng tse khothalletsang liphatsa tsa lefutso hangata a thibela tlhahiso ea liphatsa tsa lefutso. Mabaka a tikoloho a kang lijo, ho pepesehela chefo le khatello ea maikutlo a ka fetola mekhoa ea methylation ea DNA. Mohlala, lijo tse haellang bafani ba methyl joalo ka folate li ka lebisa ho hypomethylation, e ka 'nang ea susumetsa oncogenes le ho kenya letsoho kholong ea kankere.

Khatello ea Kelello
Kgatelelo ya maikutlo ke ntlha e nngwe ya bohlokwa ya tikoloho e susumetsang tlhahiso ya dijini. Kgatelelo ya kelello e kenya tshebetsong axis ya hypothalamic-pituitary-adrenal (HPA), e leng se lebisang ho lokollweng ha di-glucocorticoid. Dihormone tsena di ka sebelisana le di-receptor tsa glucocorticoid tse laolang tlhahiso ya dijini tse fapaneng tse amehang tshebetsong ya sesole sa mmele, metabolism le tshebetso ya boko. Kgatelelo ya maikutlo e sa feleng e hokahantswe le mekgwa e fetotsweng ya tlhahiso ya dijini bokong, e tlatsetsang mathateng a bophelo bo botle ba kelello a kang kgatelelo ya maikutlo le matshwenyeho. Mohlala, kgatelelo ya maikutlo e ka baka diphetoho tlhahisong ya neurotrophic factor (BDNF) e tswang bokong, e leng jini ya bohlokwa bakeng sa ho ba le botsitso ba methapo le ho mamella kgatelelo ya maikutlo.

Chefo le ditshila tsa tikoloho di na le tshusumetso e kgolo tlhahisong ya dijini. Dikhemikhale tse kang bisphenol A (BPA), tse fumanwang dipolasetiking, di ka etsisa estrogen mme tsa tlama ho di-receptor tsa estrogen, tsa fetola tlhahiso ya dijini tse amehang bophelong bo botle ba ho ikatisa le ntshetsopeleng. Ditshila tse tswang moyeng tse kang dintho tse nyenyane le benzene di amahantswe le diphetoho tlhahisong ya dijini tse amanang le mafu a ho hema le dikankere. Bafuputsi ba boetse ba fumane hore ho pepesehela dimethale tse boima tse kang loto kapa mercury ho ka baka diphetoho tsa epigenetic tse amang ntshetsopele le tshebetso ya kelello.
