The influence of APOBEC3G and deoxythymidylate kinase genetic diversity on HIV-1 hypermutation and response to treatment [PDF]

, 2006
This thesis addresses two important topics in HIV-1 medicine; (i) the clinical relevance of pre-treatment G-A hypermutation and the contribution of host and viral genetics to its development and; (ii) the influence of genetic variation in host enzymes ...

Microbiome and Tumor Microenvironment Interactions: Advances From Ecological Niches to Precision Oncology

Cancer Nexus, EarlyView.
Tumor‐associated microbiota occupies spatially organized ecological niches and influence cancer progression by reshaping tumor‐cell signaling, metabolism, immunity, stromal remodeling, and therapeutic response. Integrating microbiome‐derived biomarkers, targeted microbial interventions, spatial multi‐omics, longitudinal monitoring, and AI may enable ...

Resistance of Cyclocytidine to Cytidine Deaminase

Chemical and Pharmaceutical Bulletin, 1973
Deamination of cytidine derivatives especially of cyclocytidine by mouse kidney cytidine deaminase was examined. Cyclocytidine was not deaminated at either pH6.5 or pH7.3 by the enzyme. Furthermore, cyclocytidine did not inhibit the deamination of aracytidine and ([I]/[S])0.5 value for cyclocytidine was over 100.

Cytidine triphosphate:phosphatidic acid cytidyltransferase in Escherichia coli

Journal of Lipid Research, 1968
An enzyme has been found in particulate fractions of Escherichia coli that catalyzes the incorporation of cytidine triphosphate (CTP) into lipid in the presence of exogenous phosphatidic acid and Mg++. The product has been identified enzymatically and by

Unraveling the Multimodal Oncogenic Network of KITENIN: From Metabolic Reprogramming and Microenvironment Remodeling to Targeted Interventions

Cancer Nexus, EarlyView.
ABSTRACT KAI1 C‐terminal interacting tetraspanin (KITENIN) is an emerging oncogenic regulator associated with tumorigenesis, metastasis, therapeutic resistance, and poor clinical outcomes. Mechanistically, KITENIN promotes tumor cell proliferation, migration, invasion, and epithelial–mesenchymal transition (EMT) by activating oncogenic pathways ...

Evaluating Vaginal Microbiome Effects on Antiretroviral Exposure in the Female Genital Tract Using Pharmacometric and Machine Learning Approaches

Clinical Pharmacology &Therapeutics, EarlyView.
Antiretroviral pre‐exposure prophylaxis (PrEP) is less effective in women than expected, partly because drug exposure within the female genital tract is variable and may be influenced by the vaginal microbiome. We developed an integrated pharmacometrics and machine learning framework to evaluate associations between vaginal microbiome composition and ...

Cytidine photohydration in R17 RNA

Journal of Molecular Biology, 1972
A reductive assay for the determination of cytidine photohydrates (6-hydroxy-5,6-dihydrocytidine) in ultraviolet-irradiated RNA has been developed. The assay is based on the transformation of the unstable photohydrate into the stable reduction product N 1 -ribosyl- N 3 -( γ -hydroxypropyl)-urea in the irradiated RNA.

Double-strand break-free and transgene-free genome editing in the microalga Nannochloropsis oceanica using removable vectors containing the CRISPR base editing system

Scientific Reports
The accumulation of lipids by algae makes them attractive for carbon-neutral fuel production; however, the industrial-scale production of algal lipids has yet to be achieved.
