Muscle and peripheral nerve pathology in Alaskan Malamutes with polyneuropathy and a mutation in NDRG1.
<p>Representative cranial tibial muscle and peroneal nerve biopsy transverse sections from a two year old female Alaskan Malamute (a,b) and a three year old female Alaskan Malamute (c,d) with histopathological findings consistent with polyneuropathy. Large and small groups of atrophic fibers were present with variable severity and fatty infiltration (a,c. H&E stain). A moderate to marked depletion of myelinated fibers was evident in resin embedded nerve biopsy sections (b,d. Toluidine blue stain). Nerve fiber loss resulted from chronic axonal degeneration (arrows in b,d).</p
Multiple alignment of mammalian NDRG1 proteins.
<p>Alignment of NDRG1 protein sequences from five mammalian species: Homo sapiens, Pan troglodytes, Canis lupus, Bos taurus and Mus musculus shows a sequence similarity of 94.7%. Residue 98 (gly, marked with a frame) which is substituted in Alaskan Malamutes with the G>T mutation, is conserved in the five species.</p
