Retinal homeobox promotes cell growth, proliferation and survival of mushroom body neuroblasts in the Drosophila brain.
2016
Abstract The Drosophila mushroom bodies, centers of olfactory learning and memory in the fly ‘forebrain’, develop from a set of neural stem cells (neuroblasts) that generate a large number of Kenyon cells (KCs) during sustained cell divisions from embryonic to late pupal stage. We show that retinal homeobox ( rx ), encoding for an evolutionarily conserved transcription factor, is required for proper development of the mushroom bodies. Throughout development rx is expressed in mushroom body neuroblasts (MBNBs), their ganglion mother cells (MB-GMCs) and young KCs. In the absence of rx function, MBNBs form correctly but exhibit a reduction in cell size and mitotic activity, whereas overexpress…
Waste not, want not: Report of a completely calcified C1-C2 juxtafacet cyst and literature review
2021
Background: Calcified juxtafacet cysts in the cervical spine are extremely rate. Such symptomatic cysts commonly cause neck pain, radiculopathy, or even myelopathy. MR and CT studies typically document cord/ root compression. On occasion, some of these cysts will spontaneously regress, while many others may warrant surgical removal. Case Description: A 70-year-old male presented with a 2-year history of a progressive tetraparesis. The preoperative MR/CT studies showed a C1-C2 left extradural mass occupying more than half of the spinal canal. On MR, it was homogeneously hypointense on both T1- and T2-weighted images, while the CT showed a calcified cyst. Intraoperative and histopathological…
