Regulation of the G2/M Transition in Rodent Oocytes [PDF]
, 2010 Regulation of maturation in meiotically competent mammalian oocytes is a complex process involving the carefully coordinated exchange of signals between the somatic and germ cell compartments of the ovarian follicle via paracrine and cell–cell coupling ...

Advanced Science, EarlyView.This work demonstrates that endothelial EphA4 limits Tie2 activation and curbs leptomeningeal collateral expansion after ischemic stroke. Pharmacological activation of Tie2 by an Ang‐1 mimetic or genetic loss of EphA4 stimulates collateral vessel growth, improves cerebral perfusion, and enhances neurological recovery.

The dynamics of replication licensing in live Caenorhabditis elegans embryos [PDF]
, 2012 Accurate DNA replication requires proper regulation of replication licensing, which entails loading MCM-2-7 onto replication origins. In this paper, we provide the first comprehensive view of replication licensing in vivo, using video microscopy of ...

PLoS Biology, 2009 Apomixis, or asexual clonal reproduction through seeds, is of immense interest due to its potential application in agriculture. One key element of apomixis is apomeiosis, a deregulation of meiosis that results in a mitotic-like division. We isolated and characterised a novel gene that is directly involved in controlling entry into the second meiotic ...

Advanced Science, EarlyView.This article presents a detailed ultrastructural cell atlas of Plasmodium ookinete development using advanced volume electron microscopy (v) techniques. It defines seven distinct developmental stages, revealing complex organelle interactions and offering new insights into parasite differentiation.

The life cycles of cryptogams [PDF]
, 1991 Meiosis and karyogamy are recognized as control points in the life cycle of cryptogams. The control of meiosis is evidently complex and in yeast, and by analogy in all cryptogams, involves progressive gene activation.

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]
, 2009 Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.

Advanced Science, EarlyView.The quantitative proteomic and phosphoproteomic profiling reveals dynamic phosphorylation regulation of sperm morphogenesis. Kinase‐substrate phosphorylation network and phosphorylation module analysis, followed by in vivo knockdown and knockout analysis, identify TTBK2 and CSNK1G1 as key regulators of morphogenesis, including head, flagellar, and ...

Advanced Science, EarlyView.Genomic data offer a powerful tool for studying the molecular interactions between parasites and their hosts, but they remain scarce for parasitic monogenean flatworms. This study presents the first high‐quality phased genome assembly for monogeneans (Gyrodactylus kobayashii), and uses it to predict key interacting proteins between monogenean parasite ‐
