Luminal acidification of diverse organelles by V-ATPase in animal cells [PDF]

open access: yes, 2000
Eukaryotic cells contain organelles bounded by a single membrane in the cytoplasm. These organelles have differentiated to carry out various functions in the pathways of endocytosis and exocytosis. Their lumina are acidic, with pH ranging from 4.5 to 6.5.

Unraveling Lysosomal Exocytosis: From Molecular Mechanisms to Physiological Functions

open access: yesTraffic, Volume 27, Issue 1, March 2026.
Lysosomal exocytosis is propelled by specific molecular mechanisms that direct its microtubule‐dependent transport and subsequent fusion with the plasma membrane. This process fulfills essential physiological functions such as plasma membrane repair, maintenance of cellular homeostasis, and participation in signal transduction.

Subunit rotation in single FRET-labeled F1-ATPase hold in solution by an anti-Brownian electrokinetic trap

open access: yes, 2013
FoF1-ATP synthase catalyzes the synthesis of adenosine triphosphate (ATP). The F1 portion can be stripped from the membrane-embedded Fo portion of the enzyme.

Genomic Reconstruction of an Uncultured Hydrothermal Vent Gammaproteobacterial Methanotroph (Family Methylothermaceae) Indicates Multiple Adaptations to Oxygen Limitation [PDF]

open access: yes, 2015
Hydrothermal vents are an important contributor to marine biogeochemistry, producing large volumes of reduced fluids, gasses, and metals and housing unique, productive microbial and animal communities fueled by chemosynthesis.

Transcriptome Differentiation of Wild and Hatchery‐Reared Gibelion catla Fish in Bangladesh

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT Transcriptome differences between wild and hatchery‐reared Gibelion catla collected from Halda (HL) and Padma River (PD) as wild and a hatchery (HR) population in Bangladesh were identified in this study. A total of 6780 differentially expressed genes (DEGs) in HL compared to HR indicated significant variations in gene expression consistent ...

Gut Microbial Variations Associated With Proton Pump Inhibitor Use in the Boston Puerto Rican Health Study

open access: yesPharmacology Research &Perspectives, Volume 14, Issue 1, February 2026.
ABSTRACT Proton pump inhibitors (PPI), used to treat gastrointestinal disorders, are associated with alterations in the gut microbiome. However, this is understudied in Puerto Ricans who have unique lifestyle characteristics. Puerto Ricans, including participants of the Boston‐Puerto Rican Health Study (BPRHS), report high PPI use.

Monitoring transient elastic energy storage within the rotary motors of single FoF1-ATP synthase by DCO-ALEX FRET

open access: yes, 2012
The enzyme FoF1-ATP synthase provides the 'chemical energy currency' adenosine triphosphate (ATP) for living cells. Catalysis is driven by mechanochemical coupling of subunit rotation within the enzyme with conformational changes in the three ATP binding

Distinct Roles of SLC26A3 and CFTR in Surface pH Regulation and Bicarbonate Secretion in Human Intestinal Epithelium

open access: yesActa Physiologica, Volume 242, Issue 2, February 2026.
ABSTRACT Background and Aims Colonic bicarbonate secretion is mediated by the chloride/bicarbonate exchanger SLC26A3 and the cystic fibrosis transmembrane conductance regulator (CFTR). Dysfunction of either causes luminal acidosis, altered mucus properties, and inflammation.

Root cell wall plasticity in iron homeostasis: an overlooked frontier in plant nutrition

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1699-1708, February 2026.
Summary Iron (Fe) is an essential micronutrient for plant growth and development, yet its availability in soils is often limited or excessive, leading to widespread Fe deficiency or toxicity that constrains crop productivity. While Fe uptake, transport, and signaling pathways have been well characterized, the role of the root cell wall as a dynamic ...
