Molecular Evolution of the Gene in the Subfamily Murinae.

OGP, encoded by the gene, is the major non-serum oviductal protein in most mammals. In the genome of , has been identified as a pseudogene. However, presents a functional gene.

ZP4 Is Present in Murine Zona Pellucida and Is Not Responsible for the Specific Gamete Interaction.

Mammalian eggs are surrounded by an extracellular matrix called the zona pellucida (ZP). This envelope participates in processes such as acrosome reaction induction, sperm binding, protection of the oviductal embryo, and may be involved in speciation. In eutherian mammals, this coat is formed of three or four glycoproteins (ZP1-ZP4).

Composition of marsupial zona pellucida: a molecular and phylogenetic approach.

The zona pellucida (ZP) is an extracellular matrix that surrounds mammalian oocytes. In eutherians it is formed from three or four proteins (ZP1, ZP2, ZP3, ZP4). In the few marsupials that have been studied, however, only three of these have been characterised (ZP2, ZP3, ZP4).

Fatal ruxolitinib-related JC virus meningitis.

We report a possible association between ruxolitinib and JC virus meningitis. A 72-year-old man with myelofibrosis started treatment with ruxolitinib. Fourteen days later, the patient presented to the emergency department with fever and nausea.

Analysis of ZP1 gene reveals differences in zona pellucida composition in carnivores.

The zona pellucida (ZP) is an extracellular envelope that surrounds mammalian oocytes. This coat participates in the interaction between gametes, induction of the acrosome reaction, block of polyspermy and protection of the oviductal embryo. Previous studies suggested that carnivore ZP was formed by three glycoproteins (ZP2, ZP3 and ZP4), with ZP1 being a pseudogene.
