Rosetted Glioneuroma (RG) is a relatively new name for a type of primary brain tumor, hence not too many cases have been reported.  RG features distinct neurocytic rosettes and a glioma (similar to pilocytic astrocytoma).  Some patients previously diagnosed with Juvenile Pilocytic Astrocytoma might show characteristics of Rosetted Glioneuroma in tumor tissues.  Overexpression and/or mutation of p53 and epidermal growth factor receptor have been related to low-grade and high-grade astrocytomas. 

BioJENC is interested in developing antibodies and/or inhibitors with specificities against these altered proteins.  Other proteins related to tumor growth and apoptosis are also included in our R&D.  Progress of our R&D will be posted as it becomes available, or contact us for specific information.  If you have information that may help expedite our study, please contact us.  Together, our wish to slow or stop the growth of tumors may come true.
