Yog cov hlwb tsis xav tau ntxiv lawm, lawv tua tus kheej los ntawm ua kom muaj kev tuag hauv lub cev. Cov txheej txheem no yog vim li no hu ua programmed cell tuag, txawm hais tias nws feem ntau hu ua apoptosis (los ntawm lo lus Greek txhais tias "poob tawm," raws li nplooj ntawm tsob ntoo).
Dab tsi ua rau cov txheej txheem cell tuag?
Programmed cell death (PCD; qee zaum hu ua cellular suicide) yog kev tuag ntawm lub xovtooj raws li a tshwm sim ntawm cov xwm txheej hauv lub xovtooj, xws li apoptosis lossis autophagy. … Necrosis yog kev tuag ntawm lub xovtooj ntawm tes los ntawm lwm yam xws li kev raug mob lossis kev kis mob thiab tshwm sim ntau yam sib txawv.
Yuav ua li cas tom qab programmed cell tuag?
Nyob rau hauv programmed cell tuag, hlwb raug "cellular suicide" thaum lawv tau txais qee cov lus qhia. Apoptosis cuam tshuam txog kev tuag ntawm cov cell, tab sis nws muaj txiaj ntsig zoo rau lub cev tag nrho (piv txwv li, los ntawm kev tso cov ntiv tes los yog tshem tawm cov qog nqaij hlav cancer).
Kev tuag ntawm tes yog dab tsi thiab vim li cas nws tseem ceeb?
Programmed cell death (PCD) yog an evolutionarily conserved process in multicellular organisms uas yog ib qho tseem ceeb rau morphogenesis thaum lub sij hawm kev loj hlob thiab kev tu cov ntaub so ntswg homeostasis nyob rau hauv lub nruab nrog cev nrog rau kev loj hlob ntawm tes.
Vim li cas cell tuag tseem ceeb?
Kev tuag ntawm tes yog txheej txheem tseem ceeb hauv lub cev. Nws tshem cov hlwb hauv cov xwm txheej suav nrog: Thaum tsis xav tau cov hlwb, xws linyob rau hauv tej theem ntawm kev loj hlob. Txhawm rau tsim cov qauv hauv lub cev, piv txwv li, txheej txheej ntawm daim tawv nqaij yog ua los ntawm cov hlwb tuag.
