fertilization process stops the second arrest and terminates meiosis. The duration of oocyte full maturation is dependent on the species, in humans it can last decades [ 4 ]. In in vitro conditions, nuclear maturation is hormone-independent and is initiated by removing the oocytes from their follicular environment [ 5 ].
The proper oocyte development requires close communication with surrounding somatic cells. These cells are affected by wide range of regulatory molecules, proteins and hormones leading to proper oocyte maturation. The somatic cumulus cells (CCs) and

, according to the technical protocol, using the Affymetrix GeneAtlas Fluidics Station. The array strips were scanned employing the Imaging Station of the GeneAtlas System. Preliminary analysis of the scanned chips was performed using Affymetrix GeneAtlasTM Operating Software. The quality of gene expression data was confirmed according to the quality control criteria provided by the software. The obtained CEL files were imported into downstream data analysis software.
All of the presented analyses and graphs were compiled using Bioconductor and R programming languages

All of the presented analyses and graphs were compiled using Bioconductor and R programming languages. Each CEL file was merged with a description file. To correct background, normalize, and summarize results, we used the Robust Multiarray Averaging (RMA) algorithm. To determine the statistical significance

no doubt that implementation of advanced wild cat conservation programmes is essential. Wild felid conservation involves application of in situ methods, when a given species occurs in the natural habitat, or ex situ methods in centres with a conservation mandate ( e.g . reserves or zoos) by taking advantage of the latest advances in biotechnology, cryobiology, and bioinformatics. Besides raising and breeding animals in captivity, ex situ methods include preservation of their genetic material, usually in cell banks.
Projects aimed at conservation of the

activins which had a positive effect on follicular growth. Moreover, Salesh et al . ( 21 ) reported that insulin-like growth factor-1 (IGF-1), thyroxine, and energy-related metabolites were positively correlated with IO and closely related to reproduction. However, these studies focused on the effect of a specific endocrine or energy pathway-related factor on the normal ovarian cycle and there is only a report on metabolic profiles of postpartum dairy cows with ovarian inactivity using 1 H-nuclear magnetic resonance spectroscopy.
