Follicular dynamics, corpus luteum growth and regression in multiparous buffalo cows and buffalo heifers
Objective. Characterize the follicular dynamics and luteal growth and regression pattern of multiparous (MB) and heifer (BH) Murrah buffaloes in Colombian tropical conditions. Material and methods. Ten MB and ten BH were synchronized with a progesterone-releasing intravaginal device. No artificial insemination was performed during the estrous and daily ultrasound examinations were performed 15 ...
متن کاملApoptosis and Ovarian Follicular Atresia in Mammals
The reproductive performance of any mammalian species can be enhanced by enriching nutrition, regulating environmental factors like photoperiod, temperature, humidity etc., through selective breeding, endocrine manipulations and better management practices (Sharma, 2000; Maillet et al., 2002; Bussiere et al., 2002; Iwata et al., 2004, 2005; Rudolf, 2007; Bhardwaj and Sharma, 2011). The endocrin...
متن کاملStatus of autophagy, lysosome activity and apoptosis during corpus luteum regression in cattle
Corpus luteum (CL) regression is required during the estrous cycle. During CL regression, luteal cells stop producing progesterone and are degraded by apoptosis. However, the detailed mechanism of CL regression in cattle has not been fully elucidated. The aim of this study was to evaluate autophagy, lysosome activity, and apoptosis during CL regression in cattle. The expression of autophagy-rel...
متن کاملCaspase-3 is a pivotal mediator of apoptosis during regression of the ovarian corpus luteum.
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) derived from caspase-3 null mice would exhibit a delayed onset of apoptosis during luteal regression, when compared with CL derived from wild-type (WT) mice. To test this hypothesis, ovulation was synchronized in immature (postpar...
متن کاملOvarian VEGF165b expression regulates follicular development, corpus luteum function and fertility
Angiogenesis and vascular regression are critical for the female ovulatory cycle. They enable progression and regression of follicular development, and corpora lutea formation and regression. Angiogenesis in the ovary occurs under the control of the vascular endothelial growth factor-A (VEGFA) family of proteins, which are generated as both pro-(VEGF(165)) and anti(VEGF(165)b)-angiogenic isofor...
