Incorporation characteristics of exogenous 15N-labeled thymidine, deoxyadenosine, deoxyguanosine and deoxycytidine into bacterial DNA.

open access: yesPLoS ONE, 2020
Bacterial production has been often estimated from DNA synthesis rates by using tritium-labeled thymidine. Some bacteria species cannot incorporate extracellular thymidine into their DNA, suggesting their biomass production might be overlooked when using

One-Carbon Metabolism in Health and Disease

open access: yesCell Metabolism, 2016
One-carbon (1C) metabolism, mediated by the folate cofactor, supports multiple physiological processes. These include biosynthesis (purines and thymidine), amino acid homeostasis (glycine, serine, and methionine), epigenetic maintenance, and redox ...

Thymidine Metabolism in Neurospora crassa [PDF]

open access: yes, 1968
The metabolism of thymidine by Neurospora crassa was investigated after radioactive labeling experiments showed that thymidine is not specifically incorporated into the DNA of Neurospora; a finding in contrast to the results of labeled thymidine ...

Inactivation of the Thymidylate Synthase thyA in Non-typeable Haemophilus influenzae Modulates Antibiotic Resistance and Has a Strong Impact on Its Interplay with the Host Airways

open access: yesFrontiers in Cellular and Infection Microbiology, 2017
Antibacterial treatment with cotrimoxazol (TxS), a combination of trimethoprim and sulfamethoxazole, generates resistance by, among others, acquisition of thymidine auxotrophy associated with mutations in the thymidylate synthase gene thyA, which can ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

From M-tuberculosis thymidine monophosphate kinase (TMPKmt) inhibitors towards mitochondrial thymidine kinase (TK-2) inhibitors [PDF]

open access: yes, 2008
Here, we report on the enzyme structure-aided design of a series of substituted 3'- or 5'-thiourea derivatives of beta- and alpha-thymidine, respectively, as thymidine monophosphate kinase inhibitors of M. tuberculosis.

Clinicopathology and Diagnosis Delay in a 40-Year-Old with Mitochondrial Neurogastrointestinal Encephalomyopathy (MNGIE)

open access: yesCase Reports in Gastroenterology, 2020
Mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) is an autosomal recessive and fatal multisystem metabolic disorder. It presents with wide-ranging gastrointestinal and neurologic symptoms.

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

open access: yesMolecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Expression of Thymidine Phosphorylase in Lymph Nodes Involved with Mycosis Fungoides and Sézary Syndrome

open access: yesAdvances in Hematology, 2011
Thymidine phosphorylase may be overexpressed in both neoplastic cells and tumor stromal cells in a variety of malignancies. Our study explores thymidine phosphorylase expression in lymph nodes (LNs) from patients with mycosis fungoides (MF) or Sézary ...
