|abstract=The primary objective of this study was to compare expression of maternal transcripts in bovine oocyte populations with differential developmental competence: oocytes from prepubertal and pubertal animals; and oocytes from small (3-4 mm) and large (6-10 mm) follicles from pubertal animals. All transcripts were examined in oocytes prior to and after in vitro maturation (IVM). Genes were selected based on their known maternal effect in mouse ([[ZAR1]], STELLA, [[HSF1]], MATER/NLRP5 and its paralogue [[NLRP9]]), or their identification as markers of oocyte maturation, either involved in redox metabolism ([[PRDX1]], [[PRDX2]]) or meiotic progression (AURKA). Total or polyadenylated forms of the transcripts were followed by reverse transcription coupled to real-time PCR. Six polyadenylated transcripts were found significantly reduced after maturation irrespective of donor age or follicle diameter (p<0.05). Within these six polyadenylated transcripts, [[ZAR1]], [[NLRP9]], [[HSF1]], [[PRDX1]] and [[PRDX2]] were significantly reduced in oocytes from prepubertal animals compared to adult animals (p<0.05). A younger age was also associated with lower abundance (total form) of [[PRDX2]]/[[PRDX1]] irrespective of maturation. Total [[HSF1]], [[PRDX1]] and polyadenylated [[NLRP9]] showed a tendency (p values from 0.053 to 0.08) for a higher detection in oocytes from small follicles, thus encouraging further investigation of the follicle diameter model. However, at the present time, follicle size did not significantly affect expression of transcripts examined. In conclusion, this study demonstrates differences in the maternal store of RNA and its regulation during IVM which is dependent on donor age.
