Qhov ntawd txhais tau li cas: Feem ntau, txhua yam nws yuav siv yog kuaj ntshav lossis lub qhov ncauj swab rau lub chaw kuaj mob los qhia koj cov DNA, hais tias Erica Woodahl, Ph.D., biochemist ntawm University of Montana. "Cov tib neeg muaj tus kab mob tib yam uas tau kho nrog tib yam tshuaj muaj cov lus teb sib txawv," Woodahl piav qhia. "Yog tias peb tuaj yeem kho cov tshuaj rau ib tus neeg cov tshuaj pleev ib ce, peb tuaj yeem txhim kho qee cov lus teb thiab txo qis qhov txawv ntawm qhov tsis zoo."

Peb Nyob Qhov Twg

Ntau tus neeg-txawm tias cov neeg uas tsis mob-tseem xav paub ntxiv txog lawv cov khoom siv caj ces thiab yuav ua li cas thiaj li cuam tshuam rau lawv txoj kev pheej hmoo kis mob. Kev tshawb fawb tsis ntev los no tau pom tias 98 feem pua ​​​​ntawm cov neeg pov npav xav paub yog tias lawv cov DNA tau taw qhia tias muaj kev pheej hmoo ntau ntxiv rau cov kab mob ua rau lub neej. Ntau tus poj niam-suav nrog, nto moo tshaj plaws, Angelina Jolie-tau siv kev tshuaj ntsuam caj ces los ntsuas lawv cov kev pheej hmoo rau kab mob xws li mob qog noj ntshav lossis mob qog noj ntshav, thiab ua cov kauj ruam los daws cov kev pheej hmoo no. (Ib tug poj niam qhia "Vim li cas kuv thiaj li tau txais Alzheimer's Test.")

Thiab ntau lub tsev kho mob loj tau siv cov ntaub ntawv DNA los tsim cov kev kho mob qog noj ntshav thiab mob plawv zoo dua.

Tsis ntev los no

Raws li cov tswv yim tshiab thiab cov thev naus laus zis no tau txais, lub ntuj yog qhov txwv thaum nws los txog rau kev kho mob zoo dua lossis tshuaj tiv thaiv. Ib qho piv txwv: Cov kws tshawb fawb ntawm Washington University hauv St. Louis tsis ntev los no tau siv cov noob sequencing los sib piv cov ntaub so ntswg noj qab haus huv rau cov ntaub so ntswg ntawm peb cov neeg mob uas muaj melanoma siab heev. Los ntawm kev txheeb xyuas txhua tus neeg mob qhov kev hloov pauv ntawm cov protein tshwj xeeb, cov kws tshawb fawb muaj peev xwm tsim cov tshuaj tiv thaiv kab mob uas ua rau muaj zog ntawm cov neeg mob 'tua T-cells.

Kev tshawb fawb ntxiv xws li qhov me me no tau npaj tseg. Yog tias lawv muaj kev vam meej, txhua tus neeg mob melanoma yuav tau txais cov kev kho DNA tshwj xeeb no sai sai. Qhov ntawd tsuas yog ib qho tshwm sim-txoj cai tam sim no ntawm yuav ua li cas cov tshuaj kho tus kheej yog txhim kho kev noj qab haus huv.
