Vitamin D deficiency induces erectile dysfunction: Role of superoxide and Slpi
Background and Purpose Epidemiological studies suggest a relationship between vitamin D deficiency and erectile dysfunction (ED). We hypothesized that vitamin D deficiency or vitamin D receptor (VDR) knockout causes ED and analysed the underlying molecular mechanisms.

Background: Mechanisms coupling phosphatidylinositol (PI) 4,5-bisphosphate (PIP2) hydrolysis to its rapid replenishment remain elusive. Results: Phosphatidic acid production triggers PIP2 replenishment mediated by Nir2 and Nir3 at endoplasmic reticulum ...

GABA transporter function, oligomerization state, and anchoring: correlates with subcellularly resolved FRET [PDF]
The mouse γ-aminobutyric acid (GABA) transporter mGAT1 was expressed in neuroblastoma 2a cells. 19 mGAT1 designs incorporating fluorescent proteins were functionally characterized by [^3H]GABA uptake in assays that responded to several experimental ...

Abstract Background and Purpose TMEM16A Ca2+‐gated Cl− channels mediate depolarisation of contractile vascular cells. The anthelmintic niclosamide was reported to modulate the TMEM16A channel, suggesting possible repurposing for vascular pharmacology. Here, we investigate the mechanism of TMEM16A modulation by niclosamide and explore its effect on the ...

The cell wall regulates dynamics and size of plasma-membrane nanodomains in Arabidopsis
Significance The plant plasma membrane acts as the front line for cellular perception of the environment. As such, signaling and transport proteins which perceive or transport environmental signals, developmental cues, and nutrients are located within it.

Synaptic-like microvesicles, synaptic vesicle counterparts in endocrine cells, are involved in a novel regulatory mechanism for the synthesis and secretion of hormones [PDF]
Microvesicles in endocrine cells are the morphological and functional equivalent of neuronal synaptic vesicles. Microvesicles accumulate various neurotransmitters through a transmitter-specific vesicular transporter energized by vacuolar H+-ATPase.

Physical and functional interaction between the dopamine transporter and the synaptic vesicle protein synaptogyrin-3. [PDF]
Uptake through the dopamine transporter (DAT) represents the primary mechanism used to terminate dopaminergic transmission in brain. Although it is well known that dopamine (DA) taken up by the transporter is used to replenish synaptic vesicle stores for

Inflammation is vital for defence against injury and infection, but excessive inflammation can lead to tissue damage and disease. The central nervous system (CNS) helps regulate immune responses through neuroendocrine pathways, such as the hypothalamic–pituitary–adrenal axis and the anti‐inflammatory reflex, which limit systemic inflammation.

BCAA catabolism in brown fat controls energy homeostasis through SLC25A44. [PDF]
Branched-chain amino acid (BCAA; valine, leucine and isoleucine) supplementation is often beneficial to energy expenditure; however, increased circulating levels of BCAA are linked to obesity and diabetes.

Background and Purpose Although perivascular adipose tissue (PVAT) contains substances with contractile properties, its actions on the vascular tone are associated with the release of anticontractile substances. We hypothesize that procontractile PVAT products also exert direct effects on vascular tone. Experimental Approach Thoracic aortas from Wistar
