Historically, taste research has often been guided by the concept that there are only four (or possibly five) basic taste qualities (sweet, sour, salty, and bitter, and possibly "umami"). All other tastes have been presumed to... more
Cyclic nucleotide phosphodiesterases (PDE) are the enzymes catalyzing the hydrolysis and inactivation of the second messengers, cAMP and cGMP. Eleven PDE families are described to date, and selective inhibitors of some PDEs families are... more
Gamma-aminobutyric acid (GABA), one of the main inhibitory neurotransmitters in the brain, interacts with three types of receptors for GABA--GABA(A), GABA(B) and GABA(C). GABA(A) receptors, associated with binding sites for... more
The oviducal gland of the female of Octopus vulgaris lies about halfway along the oviduct. Progesterone and 17β-estradiol receptors have been immunolocalized in the nuclei of the cells of the glandular compartment of previtellogenic... more
In the environment, plants are exposed to plethora of adverse stimuli such as abiotic and biotic stresses. Abiotic stresses including dehydration, salinity and low temperature poses a major threat for crop productivity. Plant responds to... more
In fish, the catecholamine hormones adrenaline and noradrenaline are released into the circulation, from chromaffin cells, during numerous 'stressful' situations. The physiological and biochemical actions of these hormones (the... more
The purine nucleoside adenosine acts via four distinct adenosine receptor subtypes: the adenosine A(1), A(2A), A(2B), and A(3) receptor. They are all G protein-coupled receptors (GPCR) coupling to classical second messenger pathways such... more
Xyloglucan endotransglucosylase/hydrolases (XTHs) play roles in plant development by rearranging xyloglucan cross-links. Previously, we isolated a cDNA of XTH,VrXTH1, from mungbean that is thought to be associated with auxin-related... more
In this review, changes in brain lipid composition and metabolism due to aging are outlined. The most striking changes in cerebral cortex and cerebellum lipid composition involve an increase in acidic phospholipid synthesis. The most... more
-Protein tyrosine phosphorylation induced by arachidonic acid (AA), an important lipid second messenger, was investigated in rabbit renal proximal tubule epithelial cells. AA stimulated tyrosine phosphorylation of a number of proteins... more
Two P-type Ca transporters, the plasma membrane Ca-ATPase (PMCA) and the sarcoplasmic reticulum (SR) Ca-ATPase (SERCA), play a crucial role in maintaining Ca homeostasis, controlling contractility and contributing to excitably and cell... more
