136 HIV-1 Nef regulates activity of endoplasmic reticulum chaperone calnexin [PDF]

, 2014
HIV-1 Nef promotes viral replication by downmodulating a number of cell surface transmembrane proteins, such as CD4, MHC-I and MHC-II, which are targeted by Nef to various degradation pathways.

Lymphospecific toxicity in adenosine deaminase deficiency and purine nucleoside phosphorylase deficiency: Possible role of nucleoside kinase(s) [PDF]

Proceedings of the National Academy of Sciences, 1977
Inherited deficiencies of the enzymes adenosine deaminase (adenosine aminohydrolase; EC 3.5.4.4) and purine nucleoside phosphorylase (purine-nucleoside:orthophosphate ribosyltransferase; EC 2.4.2.1) preferentially interfere with lymphocyte development while sparing most other organ systems.

Importance of adenosine-to-inosine editing adjacent to the anticodon in an Arabidopsis alanine tRNA under environmental stress

, 2013
In all organisms, transfer RNAs (tRNAs) undergo extensive post-transcriptional modifications. Although base modifications in the anticodon are known to alter decoding specificity or improve decoding accuracy, much less is known about the functional ...

In Vitro and Clinical Evaluation of Potential Interactions of Bemnifosbuvir with Drug Transporters

The Journal of Clinical Pharmacology, EarlyView.
Abstract Bemnifosbuvir is a novel oral guanosine nucleotide prodrug candidate for the treatment of chronic hepatitis C virus infection. Potential drug–drug interactions (DDIs) of bemnifosbuvir as a substrate or perpetrator with regard to ATP‐binding cassette (ABC) and solute carrier (SLC) transporters were evaluated in vitro and in clinical studies ...

DNA methyltransferase inhibitors in hematological malignancies and solid tumors

International Journal of Cancer, Volume 158, Issue 2, Page 433-461, 15 January 2026.
Abstract Epigenetic modifications such as DNA methylation play a fundamental role in oncogenesis and the progression of neoplasms neoplasias. DNA methyltransferase inhibitors (DNMTi) constitute a family of therapeutic agents that impede the methylation at the 5‐position on cytosine nucleotides, thereby modulating the epigenetic regulation of tumor ...

CSN6 Promotes Pancreatic Cancer Progression and Gemcitabine Resistance via Antagonizing DCAF1‐Mediated Ubiquitination of NPM1

Advanced Science, Volume 13, Issue 1, 5 January 2026.
COP9 signalosome subunit 6 (CSN6) promotes the auto‐ubiquitination and degradation of DDB1‐CUL4 associated factor 1 (DCAF1), thereby antagonizing DCAF1‐mediated ubiquitination of Nucleophosmin (NPM1). This stabilization of NPM1 enhances the ribosome biogenesis process and the translation of specific gemcitabine‐resistance proteins, ultimately driving ...

Metabolism‐Regulating Nanomedicines for Cancer Therapy

Advanced NanoBiomed Research, Volume 6, Issue 1, January 2026.
This review highlights metabolism‐regulating nanomedicines designed to target glycolytic, lipid, amino acid, and nucleotide pathways in tumors. By incorporating metabolism‐regulating agents into versatile nanocarriers such as liposomes, micelles, dendrimers, and engineered bacteria, these platforms achieve targeted delivery, controlled release ...

Increased Excretion of Modified Adenine Nucleosides by Children with Adenosine Deaminase Deficiency [PDF]

Pediatric Research, 1982
We have identified seven adenine nucleosides in urines of untreated adenosine deaminase (ADA) deficient patients, four of which (adenosine, 2'-deoxyadenosine, 1-methyladenosine and N6-methyladenosine) have been previously identified in urines of normals and/or ADA deficient patients.

Non‐canonical nitric oxide signalling and DNA methylation: Inflammation induced epigenetic alterations and potential drug targets

British Journal of Pharmacology, Volume 183, Issue 1, Page 24-39, January 2026.
Abstract DNA methylation controls DNA accessibility to transcription factors and other regulatory proteins, thereby affecting gene expression and hence cellular identity and function. As epigenetic modifications control the transcriptome, epigenetic dysfunction is strongly associated with pathological conditions and ageing.

Adenosine Deaminase Deficiency and Purine Nucleoside Phosphorylase Deficiency in Common Variable Immunodeficiency [PDF]

Clinical Diagnostic Laboratory Immunology, 1998
ABSTRACTThe clinical presentations of adenosine deaminase deficiency and purine nucleoside phosphorylase deficiency are widely variable and include clinical and immunologic findings compatible with common variable immunodeficiency. The screening of 44 patients with common variable immunodeficiency failed to identify any individuals with deficiencies of
