Cloning and high level expression of bovine interferon gamma gene in eukaryotic cells (COS-7)

Interferon gamma (IFN-γ) is one of the key cytokines in defining T helper 1 lymphocyte immuneresponses. In this study, the bovine IFN-γ gene was cloned from spleen tissue RNA using the reversetranscription-polymerase chain reaction (RT-PCR). IFN-γ cDNA was sub-cloned and expressed inmammalian expression plasmid (pcDNA3.1(+)) under the control of the human cytomegalovirus (CMV)promoter. The pred...

Hormonal regulation of steroidogenic enzyme gene expression in Leydig cells.

In normal mouse Leydig cells, steady state levels of mRNA of CYP11A, 3β-hydroxysteroid dehydrogenase Δ⁵- >Δ⁴-isomerase (3βHSD), and CYP17 are differentially regulated. There is high basal expression of 3βHSD and CYP11A mRNA, while expression of CYP17 mRNA is absolutely dependent on cAMP stimulation. cAMP is required for maximal expression of all three enzymes. The expression of CYP11A in normal...

Hypocretin/orexin increases the expression of steroidogenic enzymes in human adrenocortical NCI H295R cells.

Hypocretins/orexins act through two receptor subtypes: OX(1) and OX(2). Outside the brain, orexin receptors are expressed in adrenal glands, where orexins stimulate the release of glucocorticoids. To further address the regulation of steroidogenesis, we analyzed the effect of orexins on the expression of steroidogenic enzymes in human adrenocortical National Cancer Institute (NCI) H295R cells b...

Proliferation of Luteal Steroidogenic Cells in Cattle

The rapid growth of the corpus luteum (CL) after ovulation is believed to be mainly due to an increase in the size of luteal cells (hypertrophy) rather than an increase in their number. However, the relationship between luteal growth and the proliferation of luteal steroidogenic cells (LSCs) is not fully understood. One goal of the present study was to determine whether LSCs proliferate during ...

Expression of steroidogenic enzymes in porcine polycystic ovaries.

In the present study the expression pattern of the cholesterol side-chain cleavage cytochrome (P450(scc)), 3beta-hydroxysteroid dehydrogenase (3beta-HSD) and aromatase (P450(arom)) was analyzed in the health and polycystic ovaries of gilts by means of the Western blot and immunohistochemistry. The polycystic status of ovaries was induced by i.m. dexamethasone (DXM) injections on days 7-21 of th...
