title: The expression changes of myelin and lymphocyte protein (MAL) following optic nerve crush in adult rats retinal ganglion cells.
abstract: Myelin and lymphocyte protein (MAL), a component of compact myelin, is highly expressed in oligodendrocytes and Schwann cells. It has been reported that MAL may play a vital role in the process of neuronal apoptosis following acute spinal cord injury. However, acquaintance regarding its distribution and possible function in the retina is limited. Therefore, in a rodent model of optic nerve crush (ONC), the dynamic changes of MAL in retina was detected. The expression of MAL was mainly located in the retinal ganglion cells (RGCs) and was increased strongly after ONC. The peak of MAL expression appeared on the third day. In addition, there was a concomitant upregulation of active-caspase-3, which also co-localized with MAL in RGCs. Moreover, co-localization of MAL with terminal deoxynucleotidyl transferase-mediated biotinylated-dUTP nick-end labeling (TUNEL) was detected in RGCs after ONC. Collectively, all these results suggested that the upregulation of MAL might play an important role in the pathophysiology of RGCs after ONC.
