Qhov sib txawv tseem ceeb ntawm mitogen thiab kev loj hlob yog tias mitogen yog cov protein me me uas ua rau lub cell pib faib cov cell, thaum loj hlob yog ib yam khoom tshwm sim uas muaj peev xwm ntawm stimulating cell proliferation, qhov txhab kho, thiab cellular sib txawv.
Yuav ua li cas mitogen induce ib cell loj hlob thiab faib?
Mitogens stimulated cell division los ntawm nce G1 cyclins. G1 cyclin-CDK ua rau muaj zog G1 / S cyclin-CDK los ntawm kev nce cov ntaub ntawv ntawm G1 / S cyclin thiab tshem tawm cov inhibitor ntawm G1 / S cyclin-CDK.
Cov chav kawm loj ntawm kev loj hlob yog dab tsi?
Hom Kev Loj Hlob
Chav I suav nrog kev loj hlob yam cuam tshuam nrog cov receptors tshwj xeeb ntawm lub xovtooj ntawm tes thiab suav nrog epidermal growth factor (EGF), kev loj hlob hormone (somatotropin), thiab platelet-derived growth factor (PDGF).
Lub hlwb tso tawm qhov kev loj hlob li cas?
Txoj Kev Loj Hlob, uas feem ntau suav hais tias yog ib feem ntawm cytokines, xa mus rau cov khoom siv hluav taws xob diffusible uas txhawb kev loj hlob ntawm tes, sib txawv, ciaj sia, mob, thiab kho cov ntaub so ntswg. Lawv tuaj yeem zais tau los ntawm cov hlwb nyob sib ze, cov ntaub so ntswg thiab cov qog, lossis txawm tias cov qog hlwb lawv tus kheej
mitogen txhais li cas?
: ib yam khoom uas ua rau mitosis.
