Sexual differentiation of Kiss1 gene expression in the brain of the rat.

The effect of intracerebroventricular administration of neuropeptide Y on reproductive axis function in the male Wistar rats: Involvement of hypothalamic KiSS1/GPR54 system

Several studies have shown that neuropeptide Y (NPY) is considered to be one of the key regulators of the hypothalamic-pituitary-gonadal axis in the mammals. Also, kisspeptin is a powerful upstream regulator of gonadotropin-releasing hormone neurons in the hypothalamus. The present study aims to investigate the effects of the intracerebroventricular (ICV) injection of NPY and BIBP3226 (NPY rece...

Isolation and Differentiation of Neural Stem/Progenitor Cells From Subventricular Zone of One Adult Rat

Introduction: In adult mammalian brain, neural stem cells are isolated from both the dentate gyrus and subventricular zone. This study aimed to isolate neural stem cells from adult rat subventricular zone and differentiate them into neurons and astrocytes.  Methods: In this study, the whole brain was removed after full anesthesia and creating cervical dislocation. Under a microscope, subv...

Neuronal Differentiation of Rat Hair Follicle Stem Cells: the Involvement of the Neuroprotective Factor Seladin-1 (DHCR24)

Background: The seladin-1 (selective Alzheimer disease indicator-1), also known as DHCR24, is a gene found to be down-regulated in brain region affected by Alzheimer disease (AD). Whereas, hair follicle stem cells (HFSC), which are affected in with neurogenic potential, it might to hypothesize that this multipotent cell compartment is the predominant source of seladin-1. Our aim was to evaluate...

Hypothalamic Expression of KiSS1 and RFamide-related Peptide-3 mRNAs during The Estrous Cycle of Rats

The Effect of Swimming Endurance Exercise on Cell Death and Nicotinic Acetylcholine Receptor Gene Expression in Brain of Rat: An Experimental Study of Alzheimer's Disease Model

Background and Objectives: Alzheimerchr('39')s disease (AD) is a neurodegenerative disease which is marked by impaired cholinergic function and decreased nicotinic acetylcholine receptor (nAChRs) density. nAChRs are important mediators of cholinergic signaling in modulation of learning and memory function. In Alzheimer hippocampus is particularly vulnerable to specific degenerative processes an...

Study of sex differences in the expression of β-actin gene in various tissues of the rat

Introduction: Beta-actin is a housekeeping gene, which is used as an internal standard in various biological studies. Recently, it was reported that the expression of commonly used housekeeping genes including ß–actin changes in disease states or under certain experimental conditions. Based on the reports about the effects of sex hormones on the expression of the ß- actin gene, in this study...
