Cancer yog ib pawg ntawm cov kab mob uas tshwm sim los ntawm uncontrolled cell faib uas ua rau kev loj hlob ntawm cov nqaij txawv txav. Qhov no txhais tau tias mob qog noj ntshav yog qhov tseem ceeb ntawm tus mob mitosis. Cancer hlwb loj hlob thiab faib kev tswj tsis tau los ua pawg mob qog noj ntshav cell npe qog.
Ib yam li ntawd, tib neeg nug, dab tsi yog qhov kev loj hlob ntawm tes tsis muaj zog thiab kev faib tawm hu ua?
Cancer hlwb yog hlwb ploj mus tsis ncaj ncees lawm - nyob rau hauv lwm yam lus, lawv tsis teb rau ntau lub teeb liab uas tswj cellular kev loj hlob thiab tuag. Cancer hlwb pib hauv cov ntaub so ntswg thiab, raws li lawv loj hlob thiab faib, lawv diverge puas mus ntxiv los ntawm normalcy.
Qhov thib ob, dab tsi yog kev tswj tsis tau mitosis? Kev hloov pauv hauv DNA qauv ntawm lub cell hu ua mutation. Qhov kev hloov pauv hauv DNA no ua tsis ncaj rau cov lus qhia caj ces rau mob mitosis tswj. Qhov no ua rau tswj tsis tau mitosis , uas yog qhov kev faib tawm tsis tu ncua ntawm cov hlwb, tsim ib pawg ntawm cov ntxhais tshiab, hu ua qog.
Ib yam li ntawd, nws raug nug, puas yog qhov kev faib tsis tau ntawm cov hlwb?
mitosis yog qhov tshwm sim ntawm kev tswj tsis tau ntawm kev faib cov cell.
Dab tsi yog lwm lub npe rau kev loj hlob ntawm tes tswj tsis tau?
Cancer yog dav lub sij hawm . Nws piav txog tus kab mob uas tshwm sim thaum twg cellular kev hloov ua rau lub tsis tswj kev loj hlob thiab faib ntawm hlwb . Qee hom mob qog noj ntshav ua rau mob sai kev loj hlob ntawm tes , thaum lwm tus ua hlwb rau loj hlob thiab faib ntawm tus nqi qis dua.

Hauv exocytosis, cov ntaub ntawv raug xa tawm ntawm lub xovtooj ntawm cov vesicles zais cia. Hauv txheej txheem no, theGolgi complex pob macromolecules rau hauv cov khoom thauj uas mus rau thiab fuse nrog cov ntshav ntshav

Interphase yog theem ntawm lub voj voog ntawm tes uas ib txwm siv ntawm tes siv feem ntau ntawm nws lub neej. Interphase yog 'kev ua neej nyob niaj hnub' lossis theem ntawm cov txheej txheem ntawm cov cell, uas lub cell tau txais cov as -ham thiab ua kom cov metabolism hauv lawv, loj hlob, nyeem nws cov DNA, thiab ua lwm yam haujlwm li qub ntawm tes
Dab tsi yog cov txheej txheem uas tsim ntau cov cell los ntawm ib lub cell?

Lub cell tau txais ib hom kev faib cell hu ua mitosis. Hauv mitosis, ob lub hlwb hu ua tus ntxhais cell raug tsim, txhua qhov zoo ib yam rau niam txiv cell

Ua ke, interphase thiab cell faib ua lub voj voog ntawm tes. Xam tag yam tshwm sim thaum lub sijhawm sib tham. Thaum lub sijhawm sib cuam tshuam, ib lub xovtooj ntawm tes tau nce ntxiv, sib txuas cov protein tshiab thiab cov organelles, hloov pauv nws cov chromosomes, thiab npaj rau kev faib xovtooj ntawm tes los ntawm kev tsim cov spindle proteins
Dab tsi yog txheej txheem uas lub cell faib ua ob lub cell ntxhais?

Mitosis yog txheej txheem tseem ceeb rau lub neej. Thaum lub sij hawm mitosis, lub xov tooj ntawm tes duplicates tag nrho nws cov ntsiab lus, suav nrog nws cov chromosomes, thiab sib cais los ua ob lub hlwb zoo tib yam. Vim tias cov txheej txheem no tseem ceeb heev, cov theem ntawm mitosis tau ua tib zoo tswj hwm los ntawm cov noob
