ATR inhibition facilitates targeting of leukemia dependence on convergent nucleotide biosynthetic pathways. [PDF]
, 2017 Leukemia cells rely on two nucleotide biosynthetic pathways, de novo and salvage, to produce dNTPs for DNA replication. Here, using metabolomic, proteomic, and phosphoproteomic approaches, we show that inhibition of the replication stress sensing kinase ...

CADM1 is a strong neuroblastoma candidate gene that maps within a 3.72 Mb critical region of loss on 11q23 [PDF]
, 2008 Background: Recurrent loss of part of the long arm of chromosome 11 is a well established hallmark of a subtype of aggressive neuroblastomas. Despite intensive mapping efforts to localize the culprit 11q tumour suppressor gene, this search has been ...

Intragenomic Decarboxylation of 5‐Carboxy‐2′‐deoxycytidine [PDF]
Angewandte Chemie International Edition, 2021 AbstractCellular DNA is composed of four canonical nucleosides (dA, dC, dG and T), which form two Watson–Crick base pairs. In addition, 5‐methylcytosine (mdC) may be present. The methylation of dC to mdC is known to regulate transcriptional activity. Next to these five nucleosides, the genome, particularly of stem cells, contains three additional dC ...

Decitabine impact on the endocytosis regulator RhoA, the folate carriers RFC1 and FOLR1, and the glucose transporter GLUT4 in human tumors. [PDF]
, 2014 BackgroundIn 31 solid tumor patients treated with the demethylating agent decitabine, we performed tumor biopsies before and after the first cycle of decitabine and used immunohistochemistry (IHC) to assess whether decitabine increased expression of ...

Late-onset thymidine kinase 2 deficiency: a review of 18 cases [PDF]
, 2019 BACKGROUND: TK2 gene encodes for mitochondrial thymidine kinase, which phosphorylates the pyrimidine nucleosides thymidine and deoxycytidine. Recessive mutations in the TK2 gene are responsible for the 'myopathic form' of the mitochondrial depletion ...

Pegylated arginine deiminase synergistically increases the cytotoxicity of gemcitabine in human pancreatic cancer. [PDF]
, 2014 BackgroundPancreatic ductal adenocarcinoma has proven to be one of the most chemo-resistant among all solid organ malignancies. Several mechanisms of resistance have been described, though few reports of strategies to overcome this chemo-resistance have ...

Deoxycytidine kinase augments ATM-Mediated DNA repair and contributes to radiation resistance. [PDF]
PLoS ONE, 2014 Efficient and adequate generation of deoxyribonucleotides is critical to successful DNA repair. We show that ataxia telangiectasia mutated (ATM) integrates the DNA damage response with DNA metabolism by regulating the salvage of deoxyribonucleosides ...
