Gene expression profiling in leukemias
ثبت نشده
چکیده
Since 1845, when the term leukemia was used for the first time by Virchow, advances in biochemistry, cytogenetics, cytochemistry, immunology, and subsequently molecular biology have led to the identification of different subtypes of acute myeloid leukemia (AML). Especially during the last couple of years, the almost exponentially growing understanding of the hematopoietic system has revealed that AML demonstrates extraordinary morphological, biological, and clinical heterogeneity. Therefore, clinically relevant classification systems that reflect the underlying tumor biology are needed. In an attempt to define a biologically and clinically useful working nomenclature, the current World Health Organization (WHO) classification of myeloid neoplasms incorporated those disease characteristics that have proven to possess clinical and biological relevance. This effort resulted in a more sophisticated classification that divides AML into four large subclasses, which can be further subdivided into several distinct AML subtypes (Table 1). Nevertheless, for many myeloid leukemia subtypes no specific genetic or pathogenic event has been discovered yet, and within well-defined AML subgroups such as cases with t(8;21)(q22;q22) or inv(16)(p13q22) considerable clinical heterogeneity is observed. Thus, additional subtypes may exist even within the same cytogenetic category, thereby highlighting the need to further refine the current classification of AML.

متن کاملGSK3β and CREB3 Gene Expression Profiling in Benign and Malignant Salivary Gland Tumors
Background: Salivary gland tumors (SGT) are rare lesions with uncertain histopathology. One of the major signaling pathways that participate in the development of several tumors is protein kinase A. In this pathway, glycogen synthase kinase β (GSK3β) and cAMP responsive element binding protein (CREB3) are two genes which are supposed to be down regulated in most human tumors. The expression lev...

متن کاملA role for MEIS1 in MLL-fusion gene leukemia.
Leukemias with MLL rearrangements are characterized by high expression of the homeobox gene MEIS1. In these studies, we knocked down Meis1 expression by shRNA lentivirus transduction in murine Mll-AF9 leukemia cells. Meis1 knockdown resulted in decreased proliferation and survival of murine Mll-AF9 leukemia cells. We also observed reduced clonogenic capacity and increased monocytic differentiat...
