Transgenic selection and underlying mechanisms in apicomplexan parasites

The FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.

Antioxidant supplementation blunts the proteome response to 3 weeks of sprint interval training preferentially in human type 2 muscle fibres

The Journal of Physiology, EarlyView.
Abstract figure legend Sprint interval training (SIT) is a popular time‐efficient type of endurance training. Healthy young men performed nine SIT sessions (4–6 × 30 s all‐out cycling sprints) over 3 weeks while being supplemented with antioxidants (high doses of vitamins C and E) or placebo. Muscle biopsies taken before and after the first SIT session

Prioritization of Deleterious Variations in the Human Hypoxanthine-Guanine Phosphoribosyltransferase Gene

Medical Laboratory Journal, 2018
Background and Objectives: Non-synonymous single nucleotide polymorphisms are typical genetic variations that may potentially affect the structure or function of expressed proteins, and therefore could be involved in complex disorders.

Increase in ethanol yield via elimination of lactate production in an ethanol-tolerant mutant of Clostridium thermocellum.

PLoS ONE, 2014
Large-scale production of lignocellulosic biofuel is a potential solution to sustainably meet global energy needs. One-step consolidated bioprocessing (CBP) is a potentially advantageous approach for the production of biofuels, but requires an organism ...

Molecular characterization of a carbon dioxide-dependent Escherichia coli small-colony variant isolated from blood cultures

International Journal of Medical Microbiology, 2020
A carbon dioxide-dependent small-colony variant of Escherichia coli SH4888 was isolated from blood cultures of a patient with cholangitis. To date, little is known regarding the molecular mechanisms leading to formation of carbon dioxide-dependent ...

Proteomic profile of CSF obtained at the time of diagnosis determines amyotrophic lateral sclerosis progression and survival: CXCL7 levels in disease prognosis and survival

Brain Pathology, Volume 36, Issue 5, September 2026.
Untargeted multiomic profiling of cerebrospinal fluid reveals that proteomic, but not lipidomic, signatures robustly distinguish ALS patients from controls and stratify individuals by survival, highlighting marked molecular differences between short survival and long survival disease.

De novo or Salvage? Nucleotide Availability as a Driver of Bacterial Adaptation and Virulence

MicrobiologyOpen, Volume 15, Issue 4, August 2026.
Bacterial pathogens survive in different host environments by switching between making nucleotides by de novo synthesis and scavenging them from the host. This flexibility supports growth and virulence making nucleotide metabolism an attractive therapeutic target.

Nucleotide Metabolism in Health and Disease

MedComm, Volume 7, Issue 8, August 2026.
Nucleotide metabolism, including de novo synthesis, salvage pathways, and catabolism, when dysregulated contributes to cancer, immune disorders, metabolic and urological diseases, and radiation injury. Metabolites such as adenosine, cGAMP, NAD, and cAMP and enzymes like RNR are promising therapeutic targets and biomarkers.

Evaluation of the upregulation and surface expression of hypoxanthine guanine phosphoribosyltransferase in acute lymphoblastic leukemia and Burkitt’s B cell lymphoma

Cancer Cell International, 2020
Background The aim of this study is to determine whether Hypoxanthine Guanine Phosphoribosyltransferase (HPRT) could be used as a biomarker for the diagnosis and treatment of B cell malignancies.

Characterization of guanine and hypoxanthine phosphoribosyltransferases in Methanococcus voltae

Journal of Bacteriology, 1996
Phosphoribosyltransferase (PRTase) and nucleoside phosphorylase (NPase) activities were detected by radiometric methods in extracts of Methanococcus voltae. Guanine PRTase activity was present at 2.7 nmol min(-1) mg of protein(-1) and had an apparent Km for guanine of 0.2 mM and a pH optimum of 9. The activity was inhibited 50% by 0.3 mM GMP.
