EZH2 in normal hematopoiesis and hematological malignancies
Enhancer of zeste homolog 2 (EZH2), the catalytic subunit of the Polycomb repressive complex 2, inhibits gene expression through methylation on lysine 27 of histone H3. EZH2 regulates normal hematopoietic stem cell self-renewal and differentiation. EZH2 also controls normal B cell differentiation. EZH2 deregulation has been described in many cancer types including hematological malignancies. Sp...
متن کاملMicroRNAs in Myeloid Hematological Malignancies
MicroRNAs are 19-24 nucleotides noncoding RNAs which silence modulate the expression of target genes by binding to the messenger RNAs. Myeloid malignancies include a broad spectrum of acute and chronic disorders originating from from the clonal transformation of a hematopoietic stem cell. Specific genetic abnormalities may define myeloid malignancies, such as translocation t(9;22) that represen...
متن کاملdel(13q) in myeloid malignancies
Note Chromosomal deletions are among the most common genetic events observed in hematologic malignancies; loss of genetic materiel is regarded as a hallmark of putative tumor suppressor gene localization. Deletions 13q occurs in lymphoid neoplasias: see del(13q) in non-Hodgkin's lymphoma and del(13q) in chronic lymphoproliferative diseases. In myeloid disorders, the most frequently reported del...
متن کاملPathogenic microRNA’s in myeloid malignancies
Recent studies have significantly improved our understanding of the role microRNAs (miRNAs) play in regulating normal hematopoiesis. miRNAs are critical for maintaining hematopoietic stem cell function and the development of mature progeny. Thus, perhaps it is not surprising that miRNAs serve as oncogenes and tumor suppressors in hematologic malignancies arising from hematopoietic stem and prog...
متن کاملTGFα expression in myeloid malignancies
BACKGROUND Transforming growth factor α (TGFα) is a peptide growth factor known to be expressed in normal haemopoiesis. It is also expressed in a range of epithelial neoplasms but has not been assessed in haemopoietic malignancies. We have performed an immunohistochemical evaluation of TGFα in acute and chronic myeloid malignancies. METHODS TGFα expression was semiquantitatively assessed in 6...
