OBJECTIVE To analyze both differentially expressed genes and the Bcl-xL protein expression after acute and chronic treatment with fluoxetine in rat C6 glioma cells. METHODS C6 glioma cells were cultured for 24 h or 72 h after treatment with 10 µM fluoxetine, and gene expression patterns were observed using microarray and qRT-PCR. Then, cells were cultured for 6 h, 24 h, 72 h or 96 h after tre...

BACKGROUND AND PURPOSE Recent clinical observations question that the antidepressant effect of fluoxetine (Prozac) can be explained solely with serotonin reuptake inhibition in the central nervous system. We hypothesized that fluoxetine affects the tone of vessels and thereby modulates cerebral blood flow. METHODS A small branch of rat anterior cerebral artery (195+/-15 microm in diameter at ...

Introduction: Recent studies have shown that astrocytes play major roles in normal and disease condition of the central nervous system including multiple sclerosis (MS). Molecular target therapy studies in MS have revealed that connexin-43 (Cx43) and Aquaporin-4 (AQP4) contents of astrocytes undergo expression alteration. Fluoxetine had some effects in MS patients unrelated to its known antidep...

Previous reports have shown that antidepressants increase neuronal cell proliferation and enhance neuroplasticity both in vivo and in vitro. This study investigated the direct effects of one such antidepressant, fluoxetine , on cell proliferation and on the production of neurotrophic factors in neuronal precursors derived from human embryonic stem cells (hESCs; H9). Fluoxetine induced the diffe...

The effects of fluoxetine (Prozac), a widely used antidepressant drug, on K+ channel in outer hair cells isolated from guinea pig cochlea were studied using the whole-cell patch clamp technique. Fluoxetine potently inhibited leak K+ currents with an IC50 of 0.78 microM. The inhibition was reversible and voltage-independent. At 45- to 103-fold higher concentrations than the plasma levels, fluoxe...

The selective serotonin reuptake inhibitor fluoxetine modifies social behavior in a number of species, including humans. Because the neural substrates for social behavior in prairie voles are sexually dimorphic, we tested whether the effects of fluoxetine on these behaviors differ by sex. Parental and pair-bonded voles were chronically treated with fluoxetine or saline and subsequently tested f...

The voltage-gated Nav1.5 channel is essential for the propagation of action potentials in the heart. Malfunctions of this channel are known to cause hereditary diseases. It is a prime target for class 1 antiarrhythmic drugs and a number of antidepressants. Our study investigated the Nav1.5 blocking properties of fluoxetine, a selective serotonin reuptake inhibitor. Nav1.5 channels were expresse...

BACKGROUND Generalized anxiety disorder (GAD) is a prevalent, disabling disease and is highly comorbid with other psychiatric disorders both in Western countries and the People's Republic of China. Fluoxetine, a selective inhibitor of serotonin reuptake (SSRI), is widely utilized in the management of GAD in clinical practice despite the lack of strong evidence. This article reviews fluoxetine t...

Hypersecretion of cortisol occurs in numerous patients with major depression and normalizes with clinical recovery during the course of chronic antidepressant treatment. These clinical data suggest that investigation of the effects of antidepressant treatments on the regulation of the brain-pituitary-adrenal axis may assist in elucidating the therapeutic basis of antidepressant actions. In the ...

Despite the use of fluoxetine as a first-line therapy, some patients do not show good therapeutic effect. Effective antidepressant therapy will reverse low serotonin and BDNF levels found in depression. Mozart K. 448 was reported to yield effect for Based on findings, combination depression is very rare. Therefore, this study aimed determine combined hippocampal an animal model under CUMS condi...
