The GAPs, GEFs, and GDIs of heterotrimeric G-protein alpha subunits

International Journal of Biological Sciences, 2005
The heterotrimeric G-protein alpha subunit has long been considered a bimodal, GTP-hydrolyzing switch controlling the duration of signal transduction by seven-transmembrane domain (7TM) cell-surface receptors.

Similarity Measures for Clustering SNP Data [PDF]

The issue of suitable similarity measures for a particular kind of genetic data – so called SNP data – arises from the GENICA (Interdisciplinary Study Group on Gene Environment Interaction and Breast Cancer in Germany) case-control study of sporadic ...

Characterisation of Antisense Oligonucleotides by Ion‐Pair Reversed‐Phase UHPLC‐HRMS: Method development using Design of Experiments

Journal of Mass Spectrometry, Volume 61, Issue 4, April 2026.
ABSTRACT The quality control of therapeutic antisense oligonucleotides (ASOs) poses significant analytical challenges due to the complexity of their synthesis and degradation processes and the need to ensure the safety and efficacy of active pharmaceutical ingredients (APIs).

Stronger inflammatory/cytotoxic T cell response in women identified by microarray analysis [PDF]

, 2008
Women develop chronic inflammatory autoimmune diseases like lupus more often than men. The mechanisms causing the increased susceptibility are incompletely understood, although estrogen is believed to contribute.

Hydroxyl radical footprinting modification reveals an intradomain communication pathway in EFL1 disrupted by a Shwachman‐Diamond syndrome‐associated mutation

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Shwachman‐Diamond syndrome (SDS) is a rare genetic disorder characterized by pancreatic insufficiency and neutropenia. While most cases are linked to mutations in the SBDS gene, some involve mutations in the GTPase EFL1. This protein works with SBDS to release the anti‐association factor eIF6 from the 60S ribosomal subunit during ribosome ...

Differential Gene Expression in Human Hippocampus With Aging

Aging Cell, Volume 25, Issue 4, April 2026.
2 complementary analysis from a transcriptome study in human hippocampal samples of different ages revealed a set of genes differentially expressed in aged individuals linked to inflammation and immune system pathways, DNA repair (RAD23) or neural activity.
