Consummatory Successive Negative Contrast in Mongolian Gerbil (Meriones unguiculatus)

Tyrosinase (Tyr) Gene Mutation in Albino Mongolian Gerbil (Meriones unguiculatus)

Tyrosinase is encoded by the Tyr (c or albino) locus and is the key enzyme in pigment biosynthesis. Loss of function of this enzyme caused by gene mutation results in albinism. Most cases of albinism are caused by missense mutations of tyrosinase. Albino mutations in Tyr have been identified in various animals, including human, mouse, rat, rabbit, cattle, cat, and ferret, but not in gerbil. We ...

Sequencing of cDNA encoding serum albumin and its extrahepatic synthesis in the Mongolian gerbil, Meriones unguiculatus.

We have sequenced serum albumin cDNA from liver of the Mongolian gerbil, Meriones unguiculatus. The deduced amino acid sequence showed 82.6% and 73.6% identity with the corresponding proteins from rats and humans, respectively. Identical cDNA was detected in pancreas by reverse transcription followed by polymerase chain reaction (RT-PCR). Further amplification of cDNA by nested PCR revealed the...

Dendritic Morphology of Caudal Periaqueductal Gray Projecting Retinal Ganglion Cells in Mongolian Gerbil (Meriones unguiculatus)

In this study we investigated the morphological features of the caudal periaqueductal gray (cPAG)-projecting retinal ganglion cells (RGCs) in Mongolian gerbils using retrograde labeling, in vitro intracellular injection, confocal microscopy and three-dimensional reconstruction approaches. cPAG-projecting RGCs exhibit small somata (10-17 µm) and irregular dendritic fields (201-298 µm). Sizes of ...
