FIG. 1.

Microarray analysis on 50 oocytes/type shows an overexpression of ribosomal proteins in SN oocytes. A) Scatter plot of 44K features on the NIA 60-mer oligo microarray comparing gene expression in antral oocytes (SN, green dots; NSN, red dots). Microarray data were analyzed by ANOVA-false discovery rate (FDR) statistics (averaged log intensity, FDR ≤ 0.05 and P ≤ 0.01). B) Bars representing transcripts detected in antral oocytes by ANOVA statistics and grouped according to the main Gene Ontology (GO) biological process categories they belong to. C) Heat map showing hierarchical clustering of significant ribosomal genes with one-fold expression change between SN and NSN oocytes. Expression levels are represented by the color; green indicates lower expression and red indicates higher expression.
