Serum Metabolomics in a Helicobacter hepaticus Mouse Model of Inflammatory Bowel Disease Reveal Important Changes in the Microbiome, Serum Peptides, and Intermediary Metabolism [PDF]

open access: yes, 2012
Inflammatory bowel disease (IBD) is a chronic relapsing inflammatory disorder of the bowel. The etiology remains unknown, but IBD is immune-driven and multiple factors including genetic, environmental, and microbiological components play a role ...

Heat Shock Transcription Factor OsHsfc1a Enhances Rice Seedling Thermotolerance by Regulating OsMFT1 and Preserving Chloroplast Structure Under Heat Stress

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 1898-1915, March 2026.
ABSTRACT High‐temperature stress severely threatens rice (Oryza sativa L.) growth and productivity, particularly during the seedling stage, making heat tolerance an essential breeding target. In this study, we identified the heat shock transcription factor OsHsfc1a as a positive regulator of thermotolerance in rice seedlings.

The patatin-containing phospholipase A pPLAIIα modulates oxylipin formation and water loss in Arabidopsis thaliana [PDF]

open access: yes, 2012
The patatin-related phospholipase A (pPLA) hydrolyzes membrane glycerolipids to produce monoacyl compounds and free fatty acids. Phospholipids are cleaved by pPLAIIα at the sn-1 and sn-2 positions, and galactolipids, including those containing ...

The role of lipids in the biogenesis of integral membrane proteins [PDF]

open access: yes, 2018
Most integral membrane proteins are cotranslationally inserted into the lipid bilayer. In prokaryotes, membrane insertion of the nascent chain takes place at the plasma membrane, whereas in eukaryotes insertion takes place into the endoplasmatic ...

Alternative Pathway for Methyl Supply through the Coupling of SHMT1 and PEMT to Maintain Astrocytic Homeostasis in Parkinson's Disease

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
In Parkinson's disease, SHMT1 downregulation disrupts its interaction with PEMT in astrocytes, reducing SAM levels. This leads to H3K4me1 hypomethylation and decreased Slc1a2/Glul expression, ultimately exacerbating neuroexcitotoxicity and dopaminergic neuron loss.

Identification and characterization of pptA: a gene involved in the phase-variable expression of phosphorylcholine on pili of Neisseria meningitidis [PDF]

open access: yes, 2003
Pili of pathogenic Neisseria are major virulence factors associated with adhesion, cytotoxicity, twitching motility, autoaggregation, and DNA transformation. Pili are modified posttranslationally by the addition of phosphorylcholine.

Transcriptome profiling of the rice blast fungus during invasive plant infection and in vitro stresses [PDF]

open access: yes, 2011
Background Rice blast is the most threatening disease to cultivated rice. Magnaporthe oryzae, its causal agent, is likely to encounter environmental challenges during invasive growth in its host plants that require shifts in gene expression to establish ...
