Abstract

The region surrounding the human acidic fibroblast growth factor (FGF1) locus on chromosome 5q31 is of particular interest since it represents a critical region consistently lost in acute nonlymphocytic leukemia (ANLL) or myelodysplastic syndrome (MDS) patients who have a demonstrable deletion of the distal portion of the long arm of chromosome 5. It is proposed that an ANLL/MDS leukemia suppressor gene resides on 5q31. We have previously shown that the gene is most likely localized between FGF1 and PDGFRB/CSF1R loci. The region has also been linked to at least four other genetic diseases, Treacher Collins syndrome, diastrophic dysplasia, limb-girdle muscular dystrophy, and an autosomal dominant deafness, by linkage analysis. Here, we describe yeast artificial chromosomes (YAC) spanning 450 kb around the FGF1 gene. Six YAC clones were isolated from a human YAC library and their restriction enzyme maps were determined. The overlap of the clones with each other and with FGF1 cosmid and phage clones was characterized. Three of the YAC clones were found to contain the entire FGF1 gene, which spans more than 100 kb. Proximal and distal ends of several of these YAC clones were isolated for further overlap cloning. The proximal ends o...Continue Reading

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
