Abstract
The aim of this study was to investigate the correlation between CDK1 protein and CDK1 mRNA during oocyte maturation in vivo in mouse. GV, GVBD, MI and MII oocytes were obtained from mice, respectively. Western blot validated that the CDK1 protein expression increased continuously and significantly with oocyte maturation in vivo (P<0.05). Real-time qRT-PCR showed that CDK1 mRNA expression was down-regulated significantly during transformation from GV to MI stages (P<0.05), and up-regulated significantly during transformation from MI to MII stages (P<0.05). The level of CDK1 mRNA peaked at MII stages. Spearman correlation analysis indicated that CDK1 protein expression was poor correlation with CDK1 mRNA expression during oocyte maturation in vivo (R=0.200). This finding suggested that the increase of CDK1 protein during oocyte maturation in vivo was not entirely caused by the change of transcription level. The results provide new food for thought for further research on the molecular mechanism of oocyte maturation in vivo.
期刊介绍:
The International Journal of Developmental Biology (ISSN: 0214-
6282) is an independent, not for profit scholarly journal, published by
scientists, for scientists. The journal publishes papers which throw
light on our understanding of animal and plant developmental mechanisms in health and disease and, in particular, research which elucidates the developmental principles underlying stem cell properties
and cancer. Technical, historical or theoretical approaches also fall
within the scope of the journal. Criteria for acceptance include scientific excellence, novelty and quality of presentation of data and illustrations. Advantages of publishing in the journal include: rapid
publication; free unlimited color reproduction; no page charges; free
publication of online supplementary material; free publication of audio
files (MP3 type); one-to-one personalized attention at all stages
during the editorial process. An easy online submission facility and an
open online access option, by means of which papers can be published without any access restrictions. In keeping with its mission, the
journal offers free online subscriptions to academic institutions in
developing countries.
