The protonated form of butyrate, as well as other short‐chain fatty acids (SCFAs), is membrane permeable. In acidic extracellular environments, this can lead to intracellular accumulation of SCFAs and cytosolic acidification. This phenomenon will be particularly relevant in acidic environments such as the large intestine or tumor microenvironments ...

Amino Acid Transporters in Plant Cells: A Brief Review
Amino acids are not only a nitrogen source that can be directly absorbed by plants, but also the major transport form of organic nitrogen in plants. A large number of amino acid transporters have been identified in different plant species.

Carnitine metabolism to trimethylamine by an unusual Rieske-type oxygenase from human microbiota [PDF]
Dietary intake of L-carnitine can promote cardiovascular diseases in humans through microbial production of trimethylamine (TMA) and its subsequent oxidation to trimethylamine N-oxide (TMAO) by hepatic flavin-containing monooxygenases.

The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

Effect of energy sources and levels on caecal microbial population, jejunal morphology, gene expression of jejunal transporters (sglt1, fabp) and performance of broilers under heat stress [PDF]
The present study was conducted to evaluate the effects of energy sources and levels on microbial population, jejunal morphology, gene expression of glucose transporter (SGLT1), fatty acid binding protein (FABP) and performance in broilers under heat ...

Growth and Overall Health of Patients with SLC13A5 Citrate Transporter Disorder
We were interested in elucidating the non-neurologic health of patients with autosomal recessive SLC13A5 Citrate Transporter (NaCT) Disorder. Multiple variants have been reported that cause a loss of transporter activity, resulting in significant ...

NRT2.5 a putative sodium dependent high affinity nitrate trasnporter of zostera marina l. [PDF]
Seagrasses are the only group of vascular plants that recolonized the marine environment, possibly the most severe habitat shift ever accomplished by flowering plants.

A Cl- cotransporter selective for NH4+ over K+ in glial cells of bee retina [PDF]
There appears to be a flux of ammonium (NH4+/NH3) from neurons to glial cells in most nervous tissues. In bee retinal glial cells, NH4+/NH3 uptake is at least partly by chloride-dependant transport of the ionic form NH4+.

B cells sense external mechanical forces and convert them into biochemical signals through mechanotransduction. Understanding how malignant B cells respond to physical stimuli represents a groundbreaking area of research. This review examines the key mechano‐related molecules and pathways in B lymphocytes, highlights the most relevant techniques to ...
