Retrospective natural history of thymidine kinase 2 deficiency

open access: yesJournal of Medical Genetics, 2018
Background Thymine kinase 2 (TK2) is a mitochondrial matrix protein encoded in nuclear DNA and phosphorylates the pyrimidine nucleosides: thymidine and deoxycytidine.

Effect of antiandrogen flutamide on measures of hepatic regeneration in rats [PDF]

open access: yes, 1989
Male rat liver undergoes a process of demasculinization during hepatic regeneration following partial hepatectomy. The possibility that antiandrogens might potentiate this demasculinization process and in so doing augment the hepatic regenerative ...

Nitrogen and carbon limitation of planktonic primary production and phytoplankton–bacterioplankton coupling in ponds on the McMurdo Ice Shelf, Antarctica

open access: yesEnvironmental Research Letters, 2013
We compared planktonic primary and secondary production across twenty meltwater ponds on the surface of the McMurdo Ice Shelf in January 2007, including some ponds with basal brines created by meromictic stratification.

Evidence that host size determines liver size: Studies in dogs receiving orthotopic liver transplants [PDF]

open access: yes, 1987
Orthotopic liver transplantation was performed in two groups of dogs; Group I animals consisted of large dogs that served as recipients of livers obtained from smaller dogs while Group II animals consisted of dogs that received liver from donor dogs of ...

Thymidine Catabolism as a Metabolic Strategy for Cancer Survival

open access: yesCell Reports, 2017
Thymidine phosphorylase (TP), a rate-limiting enzyme in thymidine catabolism, plays a pivotal role in tumor progression; however, the mechanisms underlying this role are not fully understood.

Anion exchange resins in phosphate form as versatile carriers for the reactions catalyzed by nucleoside phosphorylases

open access: yesBeilstein Journal of Organic Chemistry, 2020
In the present work, we suggested anion exchange resins in the phosphate form as a source of phosphate, one of the substrates of the phosphorolysis of uridine, thymidine, and 1-(β-ᴅ-arabinofuranosyl)uracil (Ara-U) catalyzed by recombinant E. coli uridine

Studies on the hyperplasia ('regeneration') of the rat liver following partial hepatectomy. Changes in lipid peroxidation and general biochemical aspects [PDF]

open access: yes, 1990
Using the experimental model of partial hepatectomy in the rat, we have examined the relationship between cell division and lipid peroxidation activity. In rats entrained to a regime of 12 h light/12 h dark and with a fixed 8 h feeding period in the dark

Fission yeast strains with circular chromosomes require the 9-1-1 checkpoint complex for the viability in response to the anti-cancer drug 5-fluorodeoxyuridine. [PDF]

open access: yesPLoS ONE, 2017
Thymidine kinase converts 5-fluorodeoxyuridine to 5-fluorodeoxyuridine monophosphate, which causes disruption of deoxynucleotide triphosphate ratios.

Cell cycle length, cell size, and proliferation rate in hydra stem cells [PDF]

open access: yes, 1990
We have analyzed the cell cycle parameters of interstitial cells in Hydra oligactis. Three subpopulations of cells with short, medium, and long cell cycles were identified. Short-cycle cells are stem cells; medium-cycle cells are precursors to nematocyte

Optimisation of the lymphocyte proliferation assay in rainbow trout (Oncorhynchus mykiss)

open access: yesVeterinární Medicína, 2019
The lymphocyte proliferation assay is a valuable method used for the evaluation of the fish immune system. However, there are many variations and optimal results are not always obtained.
