alcoholism/tyrosine

The receptor tyrosine kinases (RTKs) are a large family of proteins that transduce extracellular signals to the inside of the cell to ultimately affect important cellular functions such as cell proliferation, survival, apoptosis, differentiation, and migration. They are expressed in the nervous

We evaluated the involvement of tyrosine hydroxylase (TH) mutations in susceptibility to manic-depressive disease (MDD) and alcoholism (ALC) with a cladistics-based association analysis. Eighty-one probands with MDD, 113 probands with alcoholism, and 80 normal controls were tested for differences in

To identify sequence variants in genes that may have roles in neuronal responses to alcohol, we resequenced the 5' region of tyrosine kinase B neurotrophin receptor gene (NTRK2) and determined linkage disequilibrium (LD) values, haplotype structure, and performed association analyses using 43 single

Tyrosine hydroxylase is the rate-limiting step in the biosynthesis of catecholamines. To find variants in the tyrosine hydroxylase (TH) gene that are associated with schizophrenia, mood disorders, or alcohol dependence, all of the exons, the exon-intron boundaries, and the 5' promoter region of the

Activity of tyrosine hydroxylase (TH) was detected in human thrombocytes. The TH and monoamine oxidase (MAO) activities were estimated in thrombocytes of patients with alcoholism of various clinical manifestations. Activity of TH was increased in patients with severe abstinence disorders; after

The present study examined the association of the Tyrosine hydroxylase Val-81-Met polymorphism with alcohol dependence. One hundred and fifty-nine patients in a psychiatric unit with alcohol dependence were genotyped as well as 92 healthy volunteers. The Val allele was more frequent in patients with

Blood-brain barrier (BBB) formed by brain microvascular endothelial cells (BMVEC) regulates the passage of molecules and leukocytes in and out of the brain. Activation of matrix metalloproteinases (MMPs) and alteration of basement membrane (BM) associated with BBB injury was documented in stroke

BACKGROUND Decreased sensitivity to and increased tolerance for the effects of alcohol is a phenotype, which was shown to be associated with an increased risk for alcoholism in humans and was observed in protein tyrosine kinase (PTK) fyn knockout mice. METHODS We performed an association study of

The need to find new pharmacological targets for treating alcohol use disorder (AUD) has been an extensive effort in alcohol research. Changes in immune function due to AUD may represent an exploitable target for developing new medications to treat AUD, since the cytotoxic effect of alcohol has

Alcohol dependence is a complex disease involving polygenes, environment and their interactions. Inadequate consideration of these interactions may have hampered the progress on genome-wide association studies of alcohol dependence. By using the dataset of the Study of Addiction: Genetics and

Striatal-enriched protein tyrosine phosphatase (STEP) is a CNS-enriched protein implicated in multiple neurologic and neuropsychiatric disorders. STEP regulates key signaling proteins required for synaptic strengthening as well as NMDA and AMPA receptor trafficking. Both high and low levels of STEP

BACKGROUND Alcohol cues can precipitate the desire to drink and cause relapse in recovering alcohol-dependent patients. Serotonin and dopamine may play a role in alcohol cue-induced craving. Acute combined tryptophan (Trp), tyrosine (Tyr), and phenylalanine (Phe) depletion (CMD) in the diet

Alcohol abuse and addiction is not only a severe social problem, but also an important biological medical issue. Studies in neuropsychopharmacology and molecular neurobiology indicate that neurotransmitters and its receptors play important roles in alcohol abuse and addiction, and post-receptor

OBJECTIVE A quantitative assessment of the impact of genetic factors (density of family history of alcohol dependence and dopamine system genes polymorphisms) on the average time to relapse (ATR) after alcohol dependence treatment (duration of therapeutic remission from alcohol
