Haploidentical stem cell transplantation with post-transplant cyclophosphamide in Fanconi anemia: improving outcomes with improved supportive care in India

Only registered users can translate articles

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

Preclinical correction of human Fanconi anemia complementation group A bone marrow cells using a safety-modified lentiviral vector.

Only registered users can translate articles

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

Sleeping Beauty-mediated correction of Fanconi anemia type C.

Only registered users can translate articles

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

Mitochondrial respiratory chain Complex I defects in Fanconi anemia complementation group A.

Only registered users can translate articles

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 group J mutation abolishes its DNA repair function by uncoupling DNA translocation from helicase activity or disruption of protein-DNA complexes.

Only registered users can translate articles

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

Defective mitochondrial peroxiredoxin-3 results in sensitivity to oxidative stress in Fanconi anemia.

Only registered users can translate articles

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

Insights into strand exchange in BTB domain dimers from the crystal structures of FAZF and Miz1.

Only registered users can translate articles

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

Covalent DNA-Protein Cross-Linking by Phosphoramide Mustard and Nornitrogen Mustard in Human Cells.

Only registered users can translate articles

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

Inhibition of metalloproteinase activity in FANCA is linked to altered oxygen metabolism.

Only registered users can translate articles

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

Homocysteine inhibits neural stem cells survival by inducing DNA interstrand cross-links via oxidative stress.

Only registered users can translate articles

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

Treatment of FANCA cells with resveratrol and N-acetylcysteine: a comparative study.

Only registered users can translate articles

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

The DNA repair helicases XPD and FancJ have essential iron-sulfur domains.

Only registered users can translate articles

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

Mind the Metal: A Fragment Library-Derived Zinc Impurity Binds the E2 Ubiquitin-Conjugating Enzyme Ube2T and Induces Structural Rearrangements.

Only registered users can translate articles

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

Selective and cell-active inhibitors of the USP1/ UAF1 deubiquitinase complex reverse cisplatin resistance in non-small cell lung cancer cells.

Only registered users can translate articles

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
