D’Aurora et al. [122] | Supernumerary MII, fresh or vitrified | 16 fresh, 16 vitrified | RTqPCR | DCTN3, DCTN1, 2, and 6, PLK1 | No significant differences. |
Monzo et al. [121] | Unfertilized MII (24–78 h post-fertilization), fresh or vitrified | 17 fresh, 36 vitrified | Microarray RTqPCR validation | Global analysis (Affymetrix, HG-U133 Plus2.0) 3 genes (SLC38a2, TXNRD1, GJA1) | Significant differential expression between the non-cryopreserved and vitrified MII oocyte pools (608 genes with 509 down and 99 upregulated). Many genes of the ubiquitination pathway were downregulated. |
