Proof-of-principle studies on a strategy to enhance nucleotide imbalance specifically in cancer cells

open access: yesCell Death Discovery, 2022
Highly specific and potent inhibitors of dihydroorotate dehydrogenase (DHODH), an essential enzyme of the de novo pyrimidine ribonucleotide synthesis pathway, are in clinical trials for autoimmune diseases, viral infections and cancer.

The cyclin-dependent kinase inhibitor p57(Kip2) is epigenetically regulated in carboplatin resistance and results in collateral sensitivity to the CDK inhibitor seliciclib in ovarian cancer [PDF]

open access: yes, 2012
Carboplatin remains a first-line agent in the management of epithelial ovarian cancer (EOC). Unfortunately, platinum-resistant disease ultimately occurs in most patients.

Phosphorylation of purine and pyrimidine nucleosides by isolated rat liver mitochondria [PDF]

open access: yes, 1975
Formation of 5'-AMP, 5'-GMP, 5'-CMP and 5'UMP was confirmed in isolated rat liver mitochondria incubated with alpha-ketoglutarate, inorganic phosphate, purine nucleoside and pyrimidine nucleoside. Increased incorporation of 32Pi into ATP, GTP and UTP was

Indispensable residue for uridine binding in the uridine-cytidine kinase family

open access: yesBiochemistry and Biophysics Reports, 2017
Uridine-cytidine kinase (UCK), including human UCK2, are a family of enzymes that generally phosphorylate both uridine and cytidine. However, UCK of Thermus thermophilus HB8 (ttCK) phosphorylates only cytidine.

Exploring ABOBEC3A and APOBEC3B substrate specificity and their role in HPV positive head and neck cancer

open access: yesiScience, 2022
Summary: APOBEC3 family members are cytidine deaminases catalyzing conversion of cytidine to uracil. Many studies have established a link between APOBEC3 expression and cancer development and progression, especially APOBEC3A (A3A) and APOBEC3B (A3B ...

15N NMR study of a mixture of uniformly labeled tRNAs [PDF]

open access: yes, 1982
15N NMR spectra were taken of 15N-enriched tRNA extracted from bakers yeast; ammonium sulfate was used as a nitrogen source. The increase in the degree of denaturation of tRNA, which occurs with increase in temperature from 30 degrees C to 70 degrees C ...

Activation-induced deoxycytidine deaminase (AID) co-transcriptional scanning at single-molecule resolution [PDF]

open access: yes, 2015
Activation-induced deoxycytidine deaminase (AID) generates antibody diversity in B cells by initiating somatic hypermutation (SHM) and class-switch recombination (CSR) during transcription of immunoglobulin variable (IgV) and switch region (IgS) DNA ...
