Background: Acute myeloid leukemia (AML) is a heterogeneous clonal disorder characterized by immature myeloid cell proliferation and bone marrow failure. Various genetic and epigenetic factors have been found to be influential in such patients. Methylation silencing of APAF-1, a putative tumor suppressor gene (TSG), has been found in several human malignancies. In this study, we explored the as...
The monocyte has been perceived as a relatively inactive member of the monocyte /macrophage series, i.e., a cell in transport to an anatomic site where differentiation to the macrophage will occur. Modification of this perception is meri ted in light of the ready capacity of monocytes, as well as their tissuelocalized progeny, the elicited macrophage, to initiate and propagate coagulation prote...
Neuronal death seems to play crucial roles in the cognitive deficits of neurodegenerative diseases such as Alzheimer’s disease, Parkinson’s disease and cerebral ischemic-induced dementia. Cerebral ischemia causes the expression of an inducible type of nitric oxide (NO) synthase (iNOS) in glial cells as well as the activation of a type of neuronal NOS (nNOS) in neurons, resulting in neuronal apo...
BACKGROUND Excessive apoptosis induces unwanted cell death and promotes pathological conditions. Drug discovery efforts aimed at decreasing apoptotic damage initially targeted the inhibition of effector caspases. Although such inhibitors were effective, safety problems led to slow pharmacological development. Therefore, apoptosis inhibition is still considered an unmet medical need. METHODOLO...
Apoptotic signaling defects both promote tumorigenesis and confound chemotherapy. Typically, chemotherapeutics stimulate cytochrome c release to the cytoplasm, thereby activating the apoptosome. Although cancer cells can be refractory to cytochrome c release, many malignant cells also exhibit defects in cytochrome c-induced apoptosome activation, further promoting chemotherapeutic resistance. W...
Programmed cell death in animals is usually associated with apoptotic morphology and requires caspase activation. Necrosis and caspase-independent cell death have been reported, but mostly in experimental conditions that lead some to question their existence it in vivo. Loss of interdigital cells in the mouse embryo, a paradigm of cell death during development [1], is known to include an apopto...
We examined the expression of anti-apoptotic genes (XIAP and Bcl-2) and apoptotic genes (cytochrome c, caspase-9, Apaf-1) in tissue samples of patients with superficial bladder cancer. Thirty-two bladder cancer tissue samples (8 papillary urothelial neoplasm of low malignant potential, 10 low-grade, and 14 high-grade) and 8 normal bladder tissue samples from necropsy were used for the study of ...
