The myelodysplastic Syndromes (MDS) are a group of clonal hematopoietic stem cell diseases characterized by cytopenia(s), dysplasia in one or more of the major myeloid cell lines, ineffective hematopoiesis, and increased risk of development of acute myeloid leukemia. The classification and the diagnostic criteria have been redefined by the recent World Health Organization Classification of Tumo...
The disturbance of apoptosis molecular signaling pathways is involved in carcinogenesis. BCL2 family of proteins is the hallmark of apoptosis regulation. In the last decade, new members of BCL2 gene family were discovered and cloned and were found to be differentially expressed in many types of cancer. BCL2 protein family, through its role in regulation of apoptotic pathways, is possibly relate...
Avian cytogenetic research has, until recently, lagged far behind efforts devoted to the cytogenetics of other vertebrate groups. Avian chromosomes are inherently difficult to study because most are minute and their morphology and number are obscure. Since 1966, improved methods of culturing avian cells have resulted in more comparative chromosome studies whose quality parallels those for mamma...
BACKGROUND More than 50% of patients with myelodysplastic syndromes present cytogenetic aberrations at diagnosis. Partial or complete deletion of the long arm of chromosome 5 is the most frequent abnormality. The aim of this study was to apply fluorescence in situ hybridization of 5q31 in patients diagnosed with de novo myelodysplastic syndromes in whom conventional banding cytogenetics study h...
Pretreatment characteristics and outcome of patients treated with induction regimens containing high-dose ara-C (HiDAC) at M. D. Anderson Cancer Center refractory to 1 cycle of induction were compared with similar patients achieving a complete response (CR). Among 1597 patients treated with HiDAC-based induction from 1995 to 2009, 285 were refractory to 1 cycle. Median age was 59 years (range, ...
