Fig. 10. CXXC1-maintained histone H3K4 trimethylation and meiosis-coupled mRNA decay mediate age-associated transcriptome changes in human oocytes.

Fig. 10

Meiotic maturation-coupled mRNA translation and decay are impaired in the oocytes of aged females. Histone H3K4 trimethylation level was high in fully grown oocytes derived from young women, but gradually decreased during the aging process. The decline of CXXC1-maintained H3K4me3 level led to a wide spectrum of aging-related phenotypes, including aneuploidy after meiotic division, organelle clustering, inefficiency of mRNA transcription, translation, and clearance, anovulation, and ultimately, female infertility.
