Structural organization of the rat luteinizing hormone (LH) receptor gene.
The luteinizing hormone (LH)/human chorionic gonadotropin (hCG) receptor gene was isolated from rat liver genomic libraries and spanned at least 75 kilobase pairs from nucleotide -2057 of the 5'-flanking region to the 3'-noncoding end. The structural configuration of the coding region of the LH receptor gene consists of 11 exons separated by 10 introns that are all located within the putative e...
متن کاملAdrenarche and Skeletal Maturation during Luteinizing Hormone
During puberty the effects of adrenal androgens upon skeletal maturation are obscured by the influence of gonadal steroids. Suppression of gonadarche with an analogue of luteinizing hormone releasing hormone (LHRHa) affords an opportunity to examine the onset and progression of adrenarche in the absence of pubertal levels of gonadal steroids in a controlled fashion and to explore the relationsh...
متن کاملExpression of Luteinizing Hormone (LH) Receptor Gene in the Ovary of a Prenatally-Androgenized Rat Model of Polycystic Ovary Syndrome Following Androgen Exposure in the Prenatal Period
Introduction: Based on available evidence, exposure of the female fetus to androgens during the prenatal period, by affecting the expression of some genes, can cause polycystic ovary syndrome (PCOS) in adulthood. On the other hand, changes in luteinizing hormone (LH) levels and its receptor are associated with the risk of reproductive disorders, including PCOS. The present study aimed to evalua...
متن کاملAssociation of the genetic variants of luteinizing hormone, luteinizing hormone receptor and polycystic ovary syndrome
BACKGROUND High circulating luteinizing hormone (LH) level is a typical biochemical feature of polycystic ovary syndrome (PCOS) whose pathophysiology is still unclear. Certain mutations of LH and LH receptor (LHR) may lead to changes in bioactivity of these hormones. The aim of this study was determine the role of the LH and LHR polymorphisms in the pathogenesis of PCOS using a genetic approach...
متن کاملLuteinizing hormone receptors: specific binding of human luteinizing hormone to homogenates of luteinized rat ovaries.
Binding of human [(125)I]luteinizing hormone to homogenates of luteinized rat ovaries is dependent upon time, temperature, and pH and is saturable. Injection of human chorionic gonadotropin in vivo or addition of unlabeled human chorionic gonadotropin or human or ovine luteinizing hormone in vitro inhibits binding, whereas follicle stimulating hormone or prolactin is without effect. The dissoci...
