mechanisms of wing vein formation have been well studied in Drosophila melanogaster, however little is known about if the mechanisms are conserved to develop diversified wing vein patterns among insects. In Drosophila, Dpp, BMP2/4 ortholog, is initially expressed at longitudinal veins and later at crossveins to specify both veins during pupal stages. Using a GFP tagged Dpp, we first addressed h...

Extensive survey of meiotic metaphase II arrest during oocyte maturation in vertebrates revealed that the mitogen-activated protein kinase (MAPK) pathway regulated by the c-mos proto-oncogene product, Mos, has an essential role in cytostatic activity, termed cytostatic factor (CSF). In contrast, little is known in invertebrates in which meiotic arrest occurs in most cases at metaphase I (MI arr...
