Yeast Ste2 receptors as tools for study of mammalian protein kinases and adaptors involved in receptor trafficking [PDF]

open access: yes, 2006
BACKGROUND: Mammalian receptors that couple to effectors via heterotrimeric G proteins (e.g., beta (2)-adrenergic receptors) and receptors with intrinsic tyrosine kinase activity (e.g., insulin and IGF-I receptors) constitute the proximal points of two ...

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

open access: yesBMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Agonist versus antagonist binding to alpha-adrenergic receptors.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1980
The binding properties of two alpha-adrenergic radioligands, [3H]epinephrine (an agonist) and [3H]dihydroergocryptine (an antagonist), were compared in two model systems--membranes derived from human platelets and membranes from rat liver.

Serotonergic modulators in Alzheimer's disease: a hope in the hopeless condition

open access: yesChemistry &Biodiversity, Accepted Article.
Alzheimer disease (AD) is the main cause of dementia worldwide. AD is a progressive brain neurodegenerative disease due to genetic and environmental factors that induce a progressive accumulation of intracellular hyperphosphorylated tau protein and extracellular amyloid protein (Aβ).

The adenylate cyclase receptor complex and aqueous humor formation. [PDF]

open access: yes, 1984
The secretory tissue of the eye, the ciliary processes, contains an enzyme receptor complex, composed of membrane proteins, the catalytic moiety of the enzyme adenylate cyclase, a guanyl nucleotide regulatory protein (or N protein), and other features ...

ER/K linked GPCR-G protein fusions systematically modulate second messenger response in cells. [PDF]

open access: yes, 2017
FRET and BRET approaches are well established for detecting ligand induced GPCR-G protein interactions in cells. Currently, FRET/BRET assays rely on co-expression of GPCR and G protein, and hence depend on the stoichiometry and expression levels of the ...

Cannabinoids From Trema micranthum (L.) Blume (Cannabaceae): A Cannabinoid Profiling System

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Trema micranthum (L.) Blume is a species from the Cannabaceae botanical family, present all over the tropics. A recent study conducted by our group identified the presence of cannabidiol (CBD), Δ9‐tetrahydrocannabinol, cannabidiolic acid, and tetrahydrocannabinolic acid‐A in T. micranthum extracts.

Oral Administration of Levo-Tetrahydropalmatine Attenuates Reinstatement of Extinguished Cocaine Seeking by Cocaine, Stress or Drug-Associated Cues in Rats [PDF]

open access: yes, 2011
Cocaine addiction is characterized by a persistently heightened susceptibility to drug relapse. For this reason, the identification of medications that prevent drug relapse is a critical goal of drug abuse research.

Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Inflammation produces catecholamine resistance in obesity via activation of PDE3B by the protein kinases IKKε and TBK1. [PDF]

open access: yes, 2013
Obesity produces a chronic inflammatory state involving the NFκB pathway, resulting in persistent elevation of the noncanonical IκB kinases IKKε and TBK1.
