    The biology of miRNAs in B cell malignancies and their use as biomarkers

  • Popis výsledku v původním jazyce

    B Cell Receptor (BCR) signalling is fundamental for the maturation, survival, and proliferation of B cells, and B cell malignancies frequently harbour mutations in this pathway or complex nongenetic deregulation of BCR signalling. This pathway cross-talks with other essential pathways in the microenvironment of malignant B cells, especially B-T cell interactions and cell adhesion. This is underscored by the remarkable clinical effect of inhibitors targeting BCR-associated kinases BTK and PI3K, especially in chronic lymphocytic leukaemia (CLL). The differences in BCR signalling propensity contribute to variable prognosis in CLL and other &quot;mature&quot; B cell malignancies, and it has been shown that non-coding RNAs such as miR-150, miR-155, miR-34a or miR-17-92 play an important role in this process. The talk will focus on novel roles of microRNAs (miRNAs) in fine tuning the propensity of BCR signalling during microenvironmental interactions of B cells, and also the related changes during therapy with BCR inhibitors or classical DNA-damaging therapeutic drugs. This will include novel data on MYC-regulated and p53-regulated miRNAs acting as regulators of survival and proliferation of malignant B cells. The understanding of these miRNA functions allowed the development of several patented miRNA-based biomarkers that can be used to predict therapeutic response and/or overall survival in B cell malignancies such as chronic lymphocytic leukaemia and follicular lymphoma.
