Although KIT mutations are present in 20-25% of cases of t(8;21)(q22;q22) acute myeloid leukemia (AML), concurrent development of systemic mastocytosis (SM) is exceedingly rare. We examined the clinicopathologic features of SM associated with t(8;21)(q22;q22) AML in ten patients (six from our institutions and four from published literature) with t(8;21) AML and SM. In the majority of these case...
When treated with some DNA-damaging agents, human tumor-derived H1299 cells expressing inducible versions of wild-type or mutant p53 with inactive transactivation domain I (p53(Q22/S23)) undergo apoptosis as evidenced by cytochrome c release, nuclear fragmentation, and sub-G1 DNA content. Apoptosis induced by p53(Q22/S23) is relatively slow, however, and key downstream effector caspases are not...
Background: Mental retardation is defined as impaired mental capacity and ability to comply with environmental and social conditions. Chromosomal abnormalities are the most important causes of mental retardation. Carriers of balanced chromosomal translocation are phenotypically normal, although they may be at risk of infertility, recurrent miscarriage or giving birth to mentally retarded childr...
We report the first dry-reagent, disposable, dipstick test for molecular screening of seven chromosomal translocations associated with acute and chronic leukemia. The dipstick assay offers about 10 times higher detectability than agarose gel electrophoresis and, contrary to electrophoresis, allows confirmation of the sequence of the polymerase chain reaction (PCR) product by hybridization withi...
