The present study evaluated the occurrence of apoptosis and caspase-3 activity in the
canine corpus luteum during the period of luteal regression in eight pregnant and nine …

The human corpus luteum (CL) is a transient endocrine organ with a life span of 14–16
days. Apoptosis has been suggested to be the mechanism of CL regression and the …

Recent reports have demonstrated that prostaglandin F2α-induced generation of reactive
oxygen species or their intermediates inhibits progesterone synthesis and may also serve as …

Contents The main function of the corpus luteum (CL) is production of progesterone (P4).
Adequate luteal function to secrete P4 is crucial for determining the physiological duration of …

Production of prostaglandins (PGs) and expression of their receptors have been
demonstrated in bovine corpus luteum (CL). The aim of the present study was to determine …

Objectives were to identify cows with embryo mortality (EM) around the period of corpus
luteum maintenance by interferon tau (IFNT) and to characterize ovarian function in cows …

The corpus luteum contains differentiated steroidogenic cells that have exited the cell cycle
of proliferation. In some tissues, deletion of quiescent, differentiated cells by apoptosis in …

Contents The objective of this review is to give an overview of the signaling mechanisms
between the conceptus and the mother before implantation. The interactions between the …

Secretion of progesterone from the corpus luteum is required for normal pregnancy in all
domestic animals. However, if pregnancy does not occur following estrus and mating …

Because caspase-3 is considered a primary executioner of apoptosis and has been
implicated as a mediator of luteal regression, we hypothesized that corpora lutea (CL) …
