Ng'ombe yosinthidwa kuti ipange mkaka wa hypoallergenic

Ng'ombe yosinthidwa kuti ipange mkaka wa hypoallergenic

Ofufuza a ku Russia adalengeza kupambana kwa cloning ng'ombe, yomwe majini ake asinthidwa ndi chiyembekezo chotulutsa mkaka wotsutsa-matupi, malinga ndi British "Daily Mail".

Ng'ombe ya ng'ombe pakali pano ili ndi miyezi 14, ikulemera pafupifupi theka la tani, ndipo ikuwoneka kuti ili ndi nthawi yobereka.

“Kuyambira Meyi, ng’ombe yakhala ikugwira ntchito m’busa tsiku lililonse pakati pa ng’ombe zina zapasukuluyi,” anatero Galina Singina, wofufuza pa Ernst Federal Science Center for Animal Husbandry, ponena kuti “zinatenga nthaŵi kuti zizolowere, koma mwamsanga. zachitika."

kupambana kawiri

Kupambana kwa kuyesaku kuli pawiri, malinga ndi lipoti lochokera ku Skoltech Institute of Science and Technology ku Moscow, chifukwa ochita kafukufuku anakwanitsa kupanga cloning ng'ombe yomwe inatha kugwirizanitsa ndi ng'ombe zina zonse kuphatikizapo kusintha majini ake mwadongosolo. kusapanga mapuloteni, omwe amayambitsa tsankho la lactose mwa anthu.

Singina ndi ogwira nawo ntchito ku Skoltech Institute ndi Moscow State University adagwiritsa ntchito luso la CRISPR/Cas9 "kugogoda" majini omwe amachititsa beta-lactoglobulin, puloteni yomwe imayambitsa "lactose malabsorption," yotchedwa lactose tsankho.

Kuvuta kusintha majini a ng'ombe

Ofufuzawo adatha kuphatikizira ng'ombeyo pogwiritsa ntchito SCNT, ndi phata la cell yodziwika bwino yomwe imasamutsidwa mu dzira ndikuchotsa phata lake. Kenako mluza umene unachitikawo ankauika m’chiberekero cha ng’ombe mpaka nthawi yoberekera.

Ngakhale mbewa zosinthidwa ma genetic ndi chinthu chodziwika bwino, kusintha chibadwa cha mitundu ina kumakhala kovuta kwambiri, chifukwa cha kukwera mtengo komanso zovuta, adatero Peter Sergeev, pulofesa ku Skoltech Institute komanso wolemba nawo kafukufukuyu, zotsatira za kafukufukuyu. zomwe zimasindikizidwa mu Doklady Biochemistry ndi Biophysics.

ntchito yaikulu

"Choncho, njira yomwe imatsogolera kuswana kwa ziweto ndi mkaka wa hypoallergenic ndi ntchito yabwino," anawonjezera Sergeev.

Pafupifupi 70 peresenti ya anthu padziko lapansi ali ndi mtundu wina wa lactose malabsorption, malinga ndi National Institute of Diabetes and Digestive and Kidney Diseases, zomwe zimapangitsa kuti zikhale zovuta kwa iwo kugaya mkaka ndi zinthu zina zochokera ku mkaka.

Pulofesa Sergeev anafotokoza kuti cloning ng'ombe imodzi kwenikweni chabe mayeso, pamene sitepe yotsatira adzakhala katemera gulu la ng'ombe zambiri ndi majini kusinthidwa, kuti akhale mtundu wa ng'ombe kuti umabala mwachibadwa hypoallergenic mkaka.
