Abstract
Transient populations of cis- and trans-acting small RNAs have recently emerged as key regulators of extensive epigenetic changes taking place during periconception, which encompasses gametogenesis, fertilization, and early zygotic development. These small RNAs are not only important to maintain gen...

Abstract
I discuss recent studies of the roles of miRNAs during the maternal-to-zygotic transition and cellular reprogramming, where they reshape transcriptional landscapes to facilitate the establishment of novel cellular states....

Abstract
At fertilization, mouse sperm bind to the zona pellucida (which consists of glycoproteins ZP1, ZP2, and ZP3) that surrounds eggs. A ZP2 cleavage model of gamete recognition requires intact ZP2, and a glycan release model postulates that zona glycans are ligands for sperm. These two models were teste...

Abstract
We show that DNA demethylation in the mouse PGCs is mechanistically linked to the appearance of single-stranded DNA (ssDNA) breaks and the activation of the base excision repair (BER) pathway, as is the case in the zygote where the paternal pronucleus undergoes active DNA demethylation shortly after...

Abstract
We identified the ciliate-specific Defective in IES Excision 5 (DIE5) genes of Paramecium tetraurelia (PtDIE5) and Tetrahymena thermophila (TtDIE5) as orthologs that encode nuclear proteins expressed exclusively during development. Abrogation of PtDie5 protein (PtDie5p) function by RNA interference...

Abstract
Male germ cells are particularly susceptible to DNA damage by genotoxic agents during spermiogenesis and spermatozoal maturation, and meanwhile lack an effective repair system to eliminate the lesions. Because the DNA damaged sperm still has fertilizability and developmental potentiality, damage rep...

We consider the dynamics of sex chromosome inactivation and discuss the suggestion that the paternally inherited X chromosome preserve inactivated state in zygote. This state results from meiotic silencing and is prone to imprinted inactivation, which his observed in mammalian females at early embry...
