Chemokines in the corpus luteum: Implications of leukocyte chemotaxis
... Abstract Chemokines are small molecular weight peptides responsible for adhesion, activation, and recruitment of leukocytes into tissues. Leukocytes are thought to influence follicular atresia, ovulation, and luteal ...

Morphometric changes in the corpus luteum of pregnant hypokinetic rats
... The direct mechanisms in the corpora lutea lead- ing to the changes noted by us are unknown, but they may be at least partially related to stress reac- tion which is induced by immobilisation. In this re- action the ...

A potential function of RLIP76 in the ovarian corpus luteum
... Ral interacting protein of 76 kDa (RLIP76) is multifunctional protein localized and distributed in the plasma membrane, cytosol, and nucleus of the cell. In tumorigenesis, RLIP76 emerges as a common feature for the solid ...

Molecular regulation of progesterone synthesis in the bovine corpus luteum
... None of the treatments affected the expression of the gene for β 2 -R. This agrees well with our earlier observations that noradrenaline did not affect ei- ther the expression of the genes for StAR, 3β-HSD and cytochrome ...
