    JNK2 and p38 MAPK over-expressions do not represent key events in chronic myeloid leukemia transformation

  • Original language description

    Over-expression of JNK2 and p38 MAPK has been already observed in chronic myeloid leukemia (CML). In the present study, impacts of JNK2/p38 suppression on gene expression profile of CML cell lines were studied. After JNK2 or p38 siRNA-mediated depletion,several genes connected to cancer processes showed significant expression changes. The observation that neither JNK2 nor p38 siRNA-mediated inhibition led to significant change of CML cell proliferation suggests that there are other important, likely up-stream regulators essential for CML malignant cell growth/transformation; therefore, separate inhibition of JNK2 or p38 MAPK gene is not sufficient for a proliferation arrest.

    Zvýšená exprese JNK2 a p38 MAPK nepředstavuje klíčovou událost pro transformaci u chronické myeloidní leukemie

  • Czech description

    Zvýšená exprese JNK2 a p38 MAPK byla publikována u chronické myeloidní leukemie (CML). V této studii byl testován vliv suprese JNK2/p38 na expresní profil CML buněčných linií. Několik genů spojených s buněčnou transformací vykazovalo signifikantní změnyv expresi po inhibici JNK2/p38. Dále, pozorování, že ani JNK2 ani p38-siRNA transfekce nevede k významné změně proliferace těchto buněk, naznačuje, že inhibice genu JNK2, nebo p38 MAPK není dostatečná pro zástavu buněčného dělení u CML.
