Luteal cell-induced proliferation of T lymphocytes devoid of the nuclear progesterone receptor (PGR) is inhibited by progesterone. Functional effects of progesterone on bovine lymphocytes and the expression of membrane progesterone receptors (mPRs) alpha (PAQR7), beta (PAQR8), gamma (PAQR5), and progesterone receptor membrane component 1 (PGRMC1) mRNA were(More)
Molecular determinants and mechanisms involved in ovarian follicular growth, ovulation, and luteinization are not well understood. The objective of this study was to identify genes expressed in bovine granulosa cells (GC) of dominant follicles (DF) and downregulated after hCG-induced ovulation, using the suppression subtractive hybridization (SSH). GC were(More)
Here we describe the establishment of size-selected cDNA libraries for the cloning of full-length cDNAs that were initially identified by suppression subtractive hybridization (SSH) technology as being differentially expressed. First, the SSH-cDNA fragments were used as 32P-probes to verify their level and differential pattern of expression by virtual(More)
The corpus luteum (CL) produces oxytocin (OXT), which has been proposed to regulate the pulsatile release of prostaglandin F2alpha during luteolysis in ruminants. This action of OXT is mediated via oxytocin receptors (OXTRs) present on uterine epithelial cells. It is hypothesized that luteal OXT acts as a paracrine regulator of resident immune cells. In the(More)
The endoplasmic reticulum (ER) is a major site of protein synthesis and facilitates the folding and assembly of newly synthesized proteins. Misfolded proteins are retrotranslocated across the ER membrane and destroyed at the proteasome. DERL1 is an important protein involved in the retrotranslocation and degradation of a subset of misfolded proteins from(More)
BACKGROUND Janus kinase 3 (JAK3) is a member of the membrane-associated non-receptor tyrosine kinase protein family and is considered predominantly expressed in hematopoietic cells. We previously identified JAK3 as a differentially expressed gene in granulosa cells (GC) of bovine preovulatory follicles. The present study aimed to further investigate JAK3(More)
Secreted phosphoprotein 1 (SPP1) in the bovine corpus luteum (CL) regulates cell function during the transitional periods of luteinization and luteal regression. The objectives were to i) characterize SPP1 expression in the CL throughout the estrous cycle, ii) determine factors that regulate SPP1 expression in luteal cells, and iii) examine the role of SPP1(More)
BACKGROUND LAPTM4B is a member of the lysosome-associated transmembrane protein superfamily that is differentially expressed in normal human tissues and upregulated in various types of carcinomas. These proteins are thought to be involved in the regulation of cell proliferation and survival. The objective of this study was to investigate the expression of(More)
