Qhib cov haujlwm Meiotic hauv Cancer Xovtooj. Hauv cov txiv neej, meiosis yog ib feem tseem ceeb ntawm spermatogenesis, uas tshwm sim nyob rau hauv lub seminiferous tubules ntawm cov noob qes (10). Cov noob no paub tias yog mob qog noj ntshav /testis (CT) noob (lossis mob qog noj ntshav noob caj noob ces) thaum lawv dhau los ua haujlwm tsis zoo hauv cov nqaij mob qog noj ntshav (11-13).

HIV ua rau muaj kev pheej hmoo ntawm lwm cov kab mob thiab mob qog noj ntshav tsawg heev, suav nrog Kaposi sarcoma, tsis yog Hodgkin lymphoma thiab mob qog noj ntshav ntawm ncauj tsev menyuam
Kev sib raug zoo ntawm kev mob qog noj ntshav thiab mitosis yog dab tsi?
Mitosis yog cov txheej txheem ntawm cov hlwb loj hlob thiab sib faib, yog li rov ua dua lawv tus kheej. Mob qog noj ntshav tsuas yog tsis muaj kev tswj hwm ntawm tes. Hauv xov tooj ntawm tes, mitosis ib txwm tswj nruj. Yog tias lub xov tooj muaj qhov ua yuam kev hauv nws (ua txhaum DNA, piv txwv li), tus tswj hwm cov protein yuav tsis tso cai rau nws faib
Puas yog mob qog noj ntshav zais zis thiab mob qog noj ntshav mis?
