Inkomo eguqulwe ngokwemfuza ukuvelisa ubisi lwe-hypoallergenic

Abaphandi baseRashiya baye babhengeza impumelelo ye-cloning yenkomo, i-genetics yayo iguqulwe ngethemba lokuvelisa ubisi oluchasayo, ngokutsho kweBritish "Daily Mail".

Imazi yenkomo okwangoku ineenyanga ezili-14 ubudala, inobunzima obumalunga nesiqingatha seetoni, kwaye ibonakala inomjikelezo oqhelekileyo wokuzala.

Ukusukela ngoMeyi, inkomo ibisebenza edlelweni yonke imihla phakathi kwezinye iinkomo zeli ziko,” utshilo uGalina Singina, umphandi kwi-Ernst Federal Science Centre for Animal Husbandry, ephawula ukuba “kuthathe ixesha ukuziqhelanisa, kodwa kwakhawuleza. yenzeka.”

impumelelo kabini

Impumelelo yolu vavanyo iphindwe kabini, ngokutsho kwengxelo yeSkoltech Institute of Science and Technology eMoscow, kuba abaphandi baphumelele ukwenza imazi yenkomo ekwaziyo ukuziqhelanisa nomhlambi wonke ukongeza ekutshintsheni imizila yemfuza ngokulandelelana kwayo. ukungavelisi iprotheni, ebangela ukunganyamezeli kwelactose ebantwini.

USingina kunye noogxa bakhe kwiSkoltech Institute kunye neYunivesithi yaseMoscow State basebenzisa itekhnoloji yeCRISPR/Cas9 "ukunkqonkqoza" iijene ezinoxanduva lwe-beta-lactoglobulin, iprotein ebangela "i-lactose malabsorption," ebizwa ngokuba yi-lactose ukunganyamezeli.

Ubunzima bokuguqula imfuza yenkomo

Abaphandi bakwazi ukudibanisa inkomo ngokusebenzisa i-SCNT, kunye ne-nucleus yeseli eqhelekileyo yomnikeli idluliselwe kwiqanda kunye ne-nucleus yayo isusiwe. Imbumba efunyenweyo yayifakwa esibelekweni senkomo de ibe linqanaba lokuzala.

Ngelixa iimpuku eziguqulwe ngokwemfuza ziyinto eqhelekileyo, ukuguqula izakhi zofuzo zezinye iintlobo kunzima kakhulu, ngenxa yeendleko eziphezulu kunye nobunzima, utshilo uPeter Sergeev, unjingalwazi kwiZiko leSkoltech kunye nombhali-mbhali wophononongo, iziphumo zophando. ezipapashwa kwi-Doklady Biochemistry kunye ne-Biophysics ekuveliseni nasekuzaleni.

iprojekthi enkulu

"Ngoko, indlela ekhokelela ekuzalweni kwemfuyo ngobisi lwe-hypoallergenic yiprojekthi emangalisayo," wongezelela uSergeev.

Phantse iipesenti ezingama-70 zabemi behlabathi banengxaki yohlobo oluthile lwe-lactose malabsorption, ngokutsho kweNational Institute of Diabetes kunye neDigestive and Kidney Diseases, eyenza kube nzima kubo ukwetyisa ubisi kunye nezinye iimveliso zobisi.

Unjingalwazi uSergeev wachaza ukuba ukubumba inkomo enye luvavanyo nje, ngelixa inyathelo elilandelayo liya kuba kukugonya umhlambi weenkomo ezininzi ezinemizila yemfuza eguqulweyo, ukuze kuphuhliswe uhlobo lweenkomo oluvelisa ubisi lwendalo lwe-hypoallergenic.
