The precise localization of D1 and D2 dopamine receptors within striatal neurons and circuits is crucial information for further understanding dopamine pharmacology. We have used subtype specific polyclonal and monoclonal antibodies against D1 and D2 dopamine receptors to determine their cellular and subcellular distributions, their colocalization, and their differential connectivity with motor...
D1 receptor in interneurons of macaque prefrontal cortex: distribution and subcellular localization.
Working memory performance is influenced by dopamine activation of D1 family dopamine receptors in the prefrontal cortex; working memory performance is maximal at moderate stimulation of D1 family receptors and is reduced by either higher or lower levels of D1 stimulation. The neuronal mechanisms that underlie this complex relationship are not yet understood. Previous work from this laboratory ...
Recent studies indicate the involvement of dopamine receptors D1 and D3 in the regulation of locomotor stimulant and conditioned responses to morphine in mice. Moreover, expression of brain-derived neurotrophic factor (BDNF) may be modulated by D1 and D3 receptor activities in the nucleus accumbens (NAc) and prefrontal cortex (PFC). However, the underlying interactions between D1 and D3 recepto...
Silymarin from milk thistle (Silybum marianum) plant has been reported to show anti-cancer, anti-inflammatory, antioxidant and hepatoprotective effects. For anti-cancer activity, silymarin is known to regulate cell cycle progression through cyclin D1 downregulation. However, the mechanism of silymarin-mediated cyclin D1 downregulation still remains unanswered. The current study was performed to...
The cyclin D1 oncogene encodes the regulatory subunit of a holoenzyme that phosphorylates and inactivates the Rb protein and promotes progression through G(1) to S phase of the cell cycle. Several prostate cancer cell lines and a subset of primary prostate cancer samples have increased cyclin D1 protein expression. However, the relationship between cyclin D1 expression and prostate tumor progre...
introduction: dopamine plays an important role in the central nervous system for modulating food intake. dopamine receptors are distributed within the hypothalamus, and expression of d1 receptors is significant in hypothalamic paraventricular nucleus (pvn). therefore, the aim of this study was to find if pvn-microinjected skf38393, d1 receptor agonist, may modulate food intake. methods: guide c...
INTRODUCTION Lung cancer is a major cause of mortality and morbidity worldwide. Galectin-3 is multifunctional protein, which is involved in regulation of cell growth, cell adhesion, cell proliferation, angiogenesis and apoptosis. Cyclin D1 together with other cyclin plays an important role in cell cycle control. Cyclin D1 regulates the G1-to-S phase transition. The aim of this study was the eva...
BACKGROUND Although dopamine D1 receptors are involved in working memory, how D1 receptors contribute to this process remains unclear. Numerous studies have shown that D1 receptors have extensive functional interaction with N-methyl-D-aspartate (NMDA) receptor. Our group previously demonstrated that D1 receptors were able to regulate NMDA receptor functions through direct protein-protein intera...
