We previously reported that sorting nexin 3 (SNX3), a protein belonging to the sorting nexin family, regulates neurite outgrowth in mouse N1E-115 neuroblastoma cells. The snx3 gene is disrupted in patients with microcephaly, microphthalmia, ectrodactyly, and prognathism (MMEP) and mental retardation, demonstrating that SNX3 plays an important role in the genesis of these organs during development. The present study was designed to determine the expression pattern of snx3 mRNA, particularly in the mouse central nervous system (CNS), from the embryonic stage to adulthood. Whole mount in situ hybridization of embryonic day (E) 9.5 and 10.5 mouse embryos revealed strong positive signals for snx3 mRNA in the forebrain, pharyngeal arches, eyes, and limb buds. In situ hybridization analyses of embryonic and neonatal brain sections revealed that snx3 mRNA is mainly expressed in the cerebral cortex, hippocampus, piriform cortex, cerebellum, and spinal cord. In adulthood, the expression of snx3 mRNA is observed in the cerebral cortex, hippocampus, piriform cortex, and cerebellar neurons. Thus, snx3 mRNA is expressed during neural development and in adult neural tissues, suggesting that SNX3 may play an important role in the development and function of the CNS.

There is nothing quite as devastating as hearing that word - neuroblastoma. In seconds your world is turned upside down and your normal life is but a distant memory. You are thrust into a confusing world full of fear. Your child has cancer.

We know. We have been there. The Neuroblastoma Foundation is here for you.

Welcome to our website. It is a place for you to find answers and ask questions. One of the primary goals of the Neuroblastoma Foundation is to ensure that parents, patients and health care professionals find the information they need to make the best treatment decisions possible for children and adults affected by neuroblastoma. There is a vast amount of information throughout the internet, much of which is encapsulated in medical jargon that is so complex that even many medical professionals have difficulty in interpreting its meaning. We are here to help to decipher this information and to make sure you (and your oncologist) understand exactly what it means to you. From treatment decisions to side effects we have parents and experts that have experienced it all and are willing to distill it for you.
