The Drosophila castor gene is involved in postembryonic brain development
castor (cas) encodes a zink finger protein expressed in a subset of Drosophila embryonic neuroglioblasts where it controls neuronal differentiation. We show here that cas is expressed at larval and pupal stages in brain cell clusters where it participates in the elaboration of the adult structures. In particular using the MARCM system (mosaic analysis with a repressible cell marker), we show th...
متن کاملDpp-induced Egfr signaling triggers postembryonic wing development in Drosophila.
The acquisition of flight contributed to the success of insects and winged forms are present in most orders. Key to understanding the origin of wings will be knowledge of the earliest postembryonic events promoting wing outgrowth. The Drosophila melanogaster wing is intensely studied as a model appendage, and yet little is known about the beginning of wing outgrowth. Vein (Vn) is a neuregulin-l...
متن کاملNeuronal Diversification in the Postembryonic Drosophila Brain: A Dissertation
A functional central nervous system (CNS) is composed of numerous types of neurons. Neurons are derived from a limited number of multipotent neural stem cells. Previous studies have suggested three major strategies nature uses to diversify neurons: lineage identity specification that gives an individual neural stem cell distinct identity based on its position in the developing CNS; temporal ide...
متن کاملLineage-specific cell death in postembryonic brain development of Drosophila.
The Drosophila central brain is composed of thousands of neurons that derive from approximately 100 neuroblasts per hemisphere. Functional circuits in the brain require precise neuronal wiring and tight control of neuronal numbers. How this accurate control of neuronal numbers is achieved during neural development is largely unclear. Specifically, the role of programmed cell death in control of...
متن کاملThe Hippo Pathway Regulates Hematopoiesis in Drosophila melanogaster
The Salvador-Warts-Hippo (Hippo) pathway is an evolutionarily conserved regulator of organ growth and cell fate. It performs these functions in epithelial and neural tissues of both insects and mammals, as well as in mammalian organs such as the liver and heart. Despite rapid advances in Hippo pathway research, a definitive role for this pathway in hematopoiesis has remained enigmatic. The hema...
