fanconi anemia/cysteine

Introduction: Fanconi anemia is the most common inherited bone marrow failure syndrome, and hematopoietic stem cell transplantation (HSCT) is the only curative option. Post-transplant cyclophosphamide (PTCy) is challenging in this group

One of the major hurdles for the development of gene therapy for Fanconi anemia (FA) is the increased sensitivity of FA stem cells to free radical-induced DNA damage during ex vivo culture and manipulation. To minimize this damage, we have developed a brief transduction procedure for lentivirus

BACKGROUND The Sleeping Beauty (SB) transposon system can insert defined sequences into chromosomes to direct the extended expression of therapeutic genes. Our goal is to develop the SB system for nonviral complementation of Fanconi anemia (FA), a rare autosomal recessive disorder accompanied by

Fanconi anemia (FA) is a rare and complex inherited blood disorder of the child. At least 15 genes are associated with the disease. The highest frequency of mutations belongs to groups A, C and G. Genetic instability and cytokine hypersensitivity support the selection of leukemic over non-leukemic

Fanconi anemia (FA) is a genetic disease characterized by congenital abnormalities, bone marrow failure, and susceptibility to leukemia and other cancers. FANCJ, one of 13 genes linked to FA, encodes a DNA helicase proposed to operate in homologous recombination repair and replicational stress

Cells from patients with Fanconi anemia (FA), an inherited disorder that includes bone marrow failure and cancer predisposition, have increased sensitivity to oxidative stress through an unknown mechanism. We demonstrate that the FA group G (FANCG) protein is found in mitochondria. Wild-type but not

The BTB domain is a widely distributed protein-protein interaction motif that is often found at the N-terminus of zinc finger transcription factors. Previous crystal structures of BTB domains have revealed tightly interwound homodimers, with the N-terminus from one chain forming a two-stranded

N,N-Bis-(2-chloroethyl)-phosphorodiamidic acid (phosphoramide mustard, PM) and N,N-bis-(2-chloroethyl)-amine (nornitrogen mustard, NOR) are the two biologically active metabolites of cyclophosphamide, a DNA alkylating drug commonly used to treat lymphomas, breast cancer, certain brain cancers, and

Bone marrow (BM) failure, increased risk of myelodysplastic syndrome, acute leukaemia and solid tumors, endocrinopathies and congenital abnormalities are the major clinical problems in Fanconi anemia patients (FA). Chromosome instability and DNA repair defects are the cellular characteristics used

Elevated plasma levels of homocysteine have been implicated in neurodevelopmental and neurodegenerative disorders in human studies. Although the molecular mechanisms underlying the effects of homocysteine (Hcy) cytotoxicity on the nervous system are not yet fully unknown, induction of DNA

Fanconi anemia (FA) is a genetic disorder characterised by chromosome instability, cytokine ipersensibility, bone marrow failure and abnormal haematopoiesis associated with acute myelogenous leukemia. Recent reports are contributing to characterize the peculiar FA metabolism. Central to these

DNA helicases are essential components of the cellular machinery for DNA replication, recombination, repair, and transcription. The XPD and FancJ proteins are related helicases involved in the nucleotide excision repair (NER) and Fanconi anemia repair pathways, respectively. We demonstrate that both

Efforts to develop inhibitors, activators, and effectors of biological reactions using small molecule libraries are often hampered by interference compounds, artifacts, and false positives that permeate the pool of initial hits. Here, we report the discovery of a promising initial hit compound

Ubiquitin-specific proteases (USPs) have in recent years emerged as a promising therapeutic target class. We identified selective small-molecule inhibitors against a deubiquitinase complex, the human USP1/UAF1, through quantitative high throughput screening (qHTS) of a collection of bioactive
