Zoo. Cancer yog qhov tsis txheeb xyuas qhov kev loj hlob ntawm tes. Kev hloov pauv hauv cov noob tuaj yeem ua rau mob qog noj ntshav los ntawm kev ua kom nrawm ntawm cell faib cov nqi lossis inhibiting ib txwm tswj ntawm lub cev, xws li cell voj voog ntes lossis programmed cell tuag. Raws li qhov loj ntawm cov qog nqaij hlav loj hlob tuaj, nws tuaj yeem loj hlob mus rau hauv cov qog.
Dab tsi yog kev faib tawm ntawm cov hlwb?
Cancer yog ib yam kab mob ntawm kev tswj tsis tau ntawm tes. Nws txoj kev loj hlob thiab kev loj hlob feem ntau yog txuas mus rau cov kev hloov pauv hauv cov haujlwm ntawm lub voj voog ntawm tes regulators.
Thaum twg tsis tswj cov cell loj hlob?
Cancer yog ib pawg kab mob uas tshwm sim los ntawm kev loj hlob ntawm tes tsis muaj zog. Mob qog noj ntshav pib thaum ib leeg ntawm tes hloov pauv, ua rau muaj kev cuam tshuam ntawm cov kev tswj hwm ib txwm muaj uas ua kom cov cell faib hauv kev kuaj xyuas.
Dab tsi ua rau tsis muaj kev tswj hwm ntawm tes ntawm qib cell?
A qog suppressor gene yog ib ntu ntawm DNA uas codes rau ib qho ntawm cov kab mob tsis zoo ntawm tes. Yog tias cov noob tau hloov pauv kom cov khoom lag luam protein ua haujlwm tsawg, lub voj voog ntawm tes yuav khiav tsis txheeb.
Dab tsi yog kev tswj tsis tau mitotic cell division hu ua?
Cancer yog ib lo lus uas piav txog ntau yam kab mob uas tshwm sim los ntawm tib yam teeb meem: kev loj hlob ntawm tes tsis muaj zog. Cov qog nqaij hlav feem ntau tshwm sim vim muaj ntau qhov kev hloov pauv uas ua rau lawv sib faib sai dua, hla cov chaw kuaj xyuas thaum lub sijhawm faib cell, thiab zam kev apoptosis (kev ua haujlwm ntawm tes tuag).
