Although this process is usually of fundamental importance to almost all organisms of the animal kingdom, very little is known about the mechanisms regulating this process. Here, we describe the identification and characterization of novel mutant alleles of the ortholog of the mammalian glucuronyltransferase mutants reveal shorter larval peripheral nerves and an elongated ventral nerve cord (VNC). We show that is expressed in a subset of neurons in the central brain hemispheres, in some motoneurons of the ventral nerve cord as well as in central and peripheral nerve glia. We demonstrate that in mutants the VNC is usually under tension of shorter peripheral nerves suggesting CR1 that this VNC elongates as a consequence of tension imparted by retarded Pravadoline (WIN 48098) peripheral nerve growth during larval development. We also provide evidence that for growth of peripheral nerve fibers is critically required in hemocytes; however, glial cells are also important in this process. The glial specific gene functions as a modifier of and loss or reduction of function in a mutant background enhances VNC elongation. We propose a model in which hemocytes are required for aspects of glial cell biology which in turn affects the elongation of peripheral nerves during larval development. Our data also identifies as a first candidate gene involved Pravadoline (WIN 48098) in growth of integrated peripheral nerves and therefore establishes as an amenable in-vivo model system to study this process at the cellular and Pravadoline (WIN 48098) molecular level in more detail. Introduction During animal development and growth, the nervous system needs to expand in conjunction with the general expansion.
