The regulated production of neurons in the hippocampus throughout life underpins important brain functions such as learning and memory. Surprisingly, however, studies have so far failed to identify a resident hippocampal stem cell capable of providing the renewable source of these neurons. Here, we report that depolarizing levels of KCl produce a threefold(More)
Bombesin receptor subtype 3 (BRS-3) is a G protein coupled receptor whose natural ligand is unknown. We developed potent, selective agonist (Bag-1, Bag-2) and antagonist (Bantag-1) ligands to explore BRS-3 function. BRS-3-binding sites were identified in the hypothalamus, caudal brainstem, and several midbrain nuclei that harbor monoaminergic cell bodies.(More)
Animals that experience adverse events in early life often have life-long changes to their physiology and behavior. Long-term effects of stress during early life have been studied extensively, but less attention has been given to the consequences of negative experiences solely during the adolescent phase. Adolescence is a particularly sensitive period of(More)
A comprehensive understanding of adult neurogenesis is essential for the development of effective strategies to enhance endogenous neurogenesis in the damaged brain. Olfactory interneurons arise throughout life from stem cells residing in the subventricular zone of the lateral ventricle. Neural precursors then migrate along the rostral migratory stream(More)
We investigated the feeding behavior of mice carrying a non-functional 5-hydroxytryptamine-6 receptor (5-HT6). Homozygous mutant mice on C57BL/6 background were grossly normal and showed normal growth when fed a low-fat chow diet. When fed a high-fat diet, the mutant mice consumed approximately 8% less food while gaining approximately 35% less weight over(More)
Lysosomal acid lipase (LAL) hydrolyzes cholesteryl esters and triglycerides to generate free fatty acids and cholesterol in the cell. The downstream metabolites of these compounds serve as hormonal ligands for nuclear receptors and transcription factors. Genetic ablation of the lal gene in the mouse caused malformation of macrophages and(More)
Acute pulmonary embolism occurs in more than half a million people a year in the United States. Chronic thromboembolic pulmonary hypertension (CTEPH) develops in approximately 4% of these patients due to unresolved thromboemboli. CTEPH is thus a relatively common, progressive, and potentially fatal disease. One currently proposed theory for the poor(More)
OBJECTIVE The Activities Assessment Scale (AAS) is a 13-item postoperative functional activity scale validated in men who underwent hernia surgery. We evaluated the psychometric characteristics of the AAS in women who underwent vaginal surgery for pelvic organ prolapse (POP) and stress urinary incontinence (SUI). METHODS Participants included 163 women(More)
