Background: Aspirin is a non steroidal medicine that effects on prostaglandin, follicles, ovulation and corpus luteum. The aim of this study was to evaluate the effect of low (7.5 mg/kg) dose of Aspirin on the ovarian tissue during implantation period. Materials and Methods: Females NMRI mice 6-8 weeks old were divided into control and experimental groups. These groups were rendered pseudopre...
The primary function of the corpus luteum is secretion of the hormone progesterone, which is required for maintenance of normal pregnancy in mammals. The corpus luteum develops from residual follicular granulosal and thecal cells after ovulation. Luteinizing hormone (LH) from the anterior pituitary is important for normal development and function of the corpus luteum in most mammals, although g...
Corpus luteum is a transient and well known endocrine gland that develops from the ruptured follicles in the female vertebrate ovaries, immediately after ovulation. A major source of progesterone, this gland is concerned with gestation in the viviparous animals and retention of eggs in the oviduct in the oviparous species. Caecilians are a group of amphibians with several aspects of reproductiv...
The marked tissue remodelling associated with luteolysis involves increased expression and activity of matrix metalloproteinases (MMPs) and an influx of immune cells, notably macrophages. Since the corpus luteum expresses high concentrations of specific tissue inhibitors of MMPs, it is clear that it is not only the increased activity of MMPs that is important, but also their tissue localization...
Neat1 is a non-protein-coding RNA that serves as an architectural component of the nuclear bodies known as paraspeckles. Although cell-based studies indicate that Neat1 is a crucial regulator of gene expression, its physiological relevance remains unclear. Here, we find that Neat1 knockout (KO) mice stochastically fail to become pregnant despite normal ovulation. Unilateral transplantation of w...
