investigate the age-dependent molecular changes in a mouse model, we compared the
expression profiles of metaphase II oocytes collected from 5-to 6-week-old mice with those
collected from 42-to 45-week-old mice using the NIA 22K 60-mer oligo microarray. Among
approximately 11 000 genes whose transcripts were detected in oocytes, about 5%(530)
showed statistically significant expression changes, excluding the possibility of global …
