Fanconi anemia is a genetic disease characterized by genomic instability and cancer predisposition. Nine genes involved in Fanconi anemia have been identified; their products participate in a DNA damage-response network involving BRCA1 and BRCA2 (refs. 2,3). We previously purified a Fanconi anemia core complex containing the FANCL ubiquitin ligase and six(More)
Histone deacetylase (HDAC) inhibitors induce differentiation and/or apoptosis in a variety of cell types by activating transcription of target genes. Activation of the death receptor (DR) pathway by tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) induces apoptosis preferentially in cancer cells. Here, we investigated the intracellular(More)
FANCM is a component of the Fanconi anemia (FA) core complex and one FA patient (EUFA867) with biallelic mutations in FANCM has been described. Strikingly, we found that EUFA867 also carries biallelic mutations in FANCA. After correcting the FANCA defect in EUFA867 lymphoblasts, a "clean" FA-M cell line was generated. These cells were hypersensitive to(More)
Heterozygous carriers of germ-line mutations in the BRCA2/FANCD1, PALB2/FANCN and RAD51C/FANCO DNA repair genes have an increased lifetime risk of developing breast, ovarian and other cancers; bi-allelic mutations in these genes clinically manifest as Fanconi anemia (FA). Here, we demonstrate that RAD51C is part of a novel protein complex that contains(More)
Northeastern India is a major nasopharyngeal carcinoma (NPC) high risk-area although the rest of the country has very low incidence. A case-control study of 105 NPC cases and 115 controls was conducted to identify the potential risk factors for NPC development in this region. Information was collected by interviewer about socio-demographic characteristics,(More)
BACKGROUND We assessed the influence of sequential treatment of ionizing radiation followed by tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) on intracellular mechanisms of apoptosis of prostate tumor cells in vitro and in vivo. METHODS Prostate normal and cancer cells were exposed to irradiation and TRAIL. Four- to 6-week-old(More)
TRAIL primarily induces apoptosis in cancer cells but not in normal cells. However, some TRAIL-resistant cancer cell lines have recently been discovered. Ionizing radiation may enhance the apoptosis inducing potential of TRAIL in sensitive cells, and sensitize TRAIL-resistant cancer cells. We assessed the influence of sequential treatment of irradiation(More)
Bloom Syndrome is an autosomal recessive cancer-prone disorder caused by mutations in the BLM gene. BLM encodes a DNA helicase of the RECQ family, and associates with Topo IIIalpha and BLAP75/RMI1 (BLAP for BLM-associated polypeptide/RecQ-mediated genome instability) to form the BTB (BLM-Topo IIIalpha-BLAP75/RMI1) complex. This complex can resolve the(More)
In the present study, we aimed to elucidate the mechanism responsible for the interactive effects of histone deacetylase (HDAC) inhibitors [suberoylanilide hydroxamic acid (SAHA), MS-275, m-carboxycinnamic acid bishydroxamide (CBHA), and trichostatin-A (TSA)] and tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) on apoptosis in leukemia(More)
Fanconi anemia (FA) is a rare autosomal recessive or X-linked disorder characterized by aplastic anemia, cancer susceptibility and cellular sensitivity to DNA-crosslinking agents. Eight FA proteins (FANCA, -B, -C, -E, -F, -G, -L and -M) and three non-FA proteins (FAAP100, FAAP24 and HES1) form the FA nuclear core complex that is required for(More)
