Epigenetic Hloov Tawm Sab Nrauv Raws li cov lus qhia saum toj no, kev hloov pauv hloov pauv hloov pauv hloov pauv hauv cov kab mob tshwj xeeb thiab cov qog nqaij hlav qog tuaj yeem ua rau tsis muaj kev tswj hwm ntawm tes loj hlob thiab kev faib tawm. Txawm li cas los xij, kev hloov pauv hloov pauv tsis zoo hauv thaj chaw ntawm DNA sab nraud ntawm cov noob kuj tuaj yeem ua rau mob qog noj ntshav
Kev hloov pauv ntawm epigenetic ua rau mob qog noj ntshav li cas?
Nws zoo nkaus li tias mob qog noj ntshav yuav nquag pib los ntawm kev txo qis hauv kev qhia ntawm ib lossis ntau dua DNA kho enzymes Txo DNA kho yuav ua rau muaj kev puas tsuaj ntawm DNA. Kev ua txhaum kev hloov pauv hloov pauv yav dhau los qee qhov kev puas tsuaj DNA no tuaj yeem ua rau muaj kev hloov pauv nrog kev xaiv kom zoo dua.
Vim li cas epigenetics tseem ceeb hauv kev mob qog noj ntshav?
Kev hloov pauv hauv kev hloov pauv hauv epigenetic hauv kev mob qog noj ntshav tswj ntau cov lus teb ntawm tes, suav nrog kev loj hlob ntawm tes, apoptosis, ntxeem tau, thiab kev laus. Los ntawm DNA methylation, hloov histone, chromatin remodeling, thiab noncoding RNA kev tswj, epigenetics ua lub luag haujlwm tseem ceeb hauv cov qog nqaij hlav.
Cov kab mob dab tsi tuaj yeem ua rau epigenetics ua rau?
Kev hloov pauv ntawm Epigenetic yog lub luag haujlwm rau tib neeg cov kab mob, suav nrog Fragile X syndrome, Angelman's syndrome, Prader-Willi syndrome, thiab ntau yam qog noj ntshav.
Dab tsi yog cov kab mob qog noj ntshav?
Epigenetic (nongenotoxic) tshuaj carcinogens yog cov neeg ua haujlwm uas ua rau cov qog tsim los ntawm cov txheej txheem tshwj tsis yog kev hloov pauv ncaj qha lossis kev puas tsuaj rau DNACov tshuaj no tshwm sim los hloov pauv kev loj hlob ntawm tes thiab kev tuag ntawm tes. thiab nthuav tawm koob tshuaj teb kev sib raug zoo ntawm kev raug thiab qog tsim.

Hauv cov neeg laus, feem ntau cov qog nqaij hlav hauv nruab nrab tshwm sim nyob rau hauv anterior (pem hauv ntej) mediastinum thiab feem ntau yog malignant (cancerous) lymphomas lossis thymomas .
Puas yog kab mob qog noj ntshav ntau hom qog noj ntshav?
Multinodular goiters (MNG) tsis ntev los no tau pom tias muaj mob qog noj ntshav uas mus txog qhov nyob ib leeg thyroid nodule. Txawm li cas los xij, rab koob zoo aspiration (FNA) ntawm MNG raug txwv vim muaj ntau lub nodules . pes tsawg feem pua ntawm cov kab mob qog noj ntshav ntau ntau yog mob qog noj ntshav?
Puas yog mob qog noj ntshav ntawm cov qog ntshav qog ntshav?

Qhov twg yog mob qog noj ntshav lossis mob qog noj ntshav?
Kev tshuaj xyuas ntawm cov neeg mob coob tshaj plaws uas muaj mob qog noj ntshav ntawm lub mis(ILBC) qhia tau tias cov txiaj ntsig tau zoo dua thaum piv nrog kev mob qog noj ntshav ntawm lub mis, qhia txog qhov xav tau tseem ceeb. rau kev tshawb fawb ntxiv thiab kev sim tshuaj rau cov neeg mob nrog ILBC .
Puas yog cov qog ntshav qog ntshav qog ntshav ntev ntev?
Chronic lymphocytic leukemia feem ntau tsis tau txiav txim siab tias muaj keeb kwm caj ces. Txawm li cas los xij, muaj pov thawj tsis ncaj qha uas ib pawg ntawm CLL cov ntaub ntawv yuav raug muab rau cov qub txeeg qub teg ntawm autosomal dominant noob .
