BACKGROUND Reelin (RELN) is a glycoprotein secreted preferentially by cortical gamma-aminobutyric acid-ergic (GABAergic) interneurons (layers I and II) that binds to integrin receptors located on dendritic spines of pyramidal neurons or on GABAergic interneurons of layers III through V expressing the disabled-1 gene product (DAB1), a cytosolic adaptor(More)
Postmortem prefrontal cortices (PFC) (Brodmann's areas 10 and 46), temporal cortices (Brodmann's area 22), hippocampi, caudate nuclei, and cerebella of schizophrenia patients and their matched nonpsychiatric subjects were compared for reelin (RELN) mRNA and reelin (RELN) protein content. In all of the brain areas studied, RELN and its mRNA were(More)
BACKGROUND Suicide is a major public health concern. Although authors of many studies have examined the neurobiological aspects of suicide, the molecular mechanisms associated with suicidal behavior remain unclear. Brain-derived neurotrophic factor (BDNF), one of the most important neurotrophins, after binding with and activating receptor tyrosine kinase B(More)
The extracellular regulated kinases (ERK) 1 and ERK2 are members of mitogen-activated protein (MAP) kinase family that play an important role in transducing extracellular signals to the nucleus and have been implicated in a broad spectrum of biological responses. To test the hypothesis that MAP kinases may be involved in depression, we examined the(More)
BACKGROUND Teenage suicide is a major public health concern. Although there is some understanding of the psychosocial factors associated with teenage suicide, little is known about the neurobiologic factors of teenage suicide. Protein kinase C (PKC) is a critical phosphorylating enzyme in the phosphoinositide signaling pathway (which is involved in many(More)
BACKGROUND Brain-derived neurotrophic factor (BDNF) is a member of a neurotrophin family and is involved in many physiological functions, including cell proliferation, migration, and differentiation, and neuron survival in the human nervous system. Abnormalities of BDNF have been implicated in the pathophysiology of depression based on observations that(More)
Mood disorders are among the most prevalent and recurrent forms of psychiatric illnesses. In the last decade, there has been increased understanding of the biological basis of mood disorders. In fact, novel mechanistic concepts of the neurobiology of unipolar and bipolar disorders are evolving based on recent pre-clinical and clinical studies, most of which(More)
We studied platelet monamine oxidase (MAO) activity using 14C-tyramine as substrate in hospitalized alcoholic patients in the early phases of abstinence and in nonhospitalized normal control volunteers. Platelet MAO was determined in 75 patients (67 men, 8 women) with alcoholism and 123 normal control volunteers (52 men, 71 women). The platelet MAO activity(More)
In previous research, evidence was provided of genetic control of in vitro red blood cell (RBC) uptake of lithium ion following a 24-hour incubation using a monozygotic (MZ)-dizygotic (DZ) twin study method. To extend these data, in vitro RBC lithium ion concentrations were assessed for five MZ and five DZ twin pairs. To extend this line of research on(More)
