[Expression analysis of mouse homologous proteins with human aldose reductase like-1].
OBJECTIVE
To detect expression of mouse ARL-1 homologous proteins in mouse tissues, and analyze homology, genetic distance and phylogenetic relationship between human aldose reductase like-1 (ARL-1) and mouse homologous proteins.


METHODS
Homology of mouse ARL-1 homologous proteins with human ARL-1 was analyzed by software Clustal X 1.8 using GenBank and Swiss-Prot database; genetic distance and phylogenetic relationship between mouse ARL-1 homologous proteins and human ARL-1 were analyzed by software Mega 2.0; mouse tissues were detected by Western blotting using polyclonal antibodies against ARL-1 protein from domestic rabbits.


RESULTS
The amino acid sequence of human ARL-1 was 83%, 82%, 81%, 79%, 70%, 51%, 50% and 45% identical to that of the Chinese hamster ovary reductase (CHO-Red), the mouse fibroblast growth factor-regulated protein (FR-1), rat aldose reductase-like protein (rARLP), the mouse vas deferens protein (MVDP), rat lens aldose reductase (LeAR), delta4-3-ketosteroid-5beta-reductase (5beta-Red), rat aldo-keto reductase protein c (RaK-c) and 3alpha-hydroxysteroid dehydrogenase (3alpha-HSD). Among all the mouse ARL-1 homologous proteins, the genetic distance between CHO-Red and human ARL was the shortest (18.0%, P = 0.023), next was FR-1 (19.1%, P=0.023) and rARLP (19.9%, P = 0.025). From the phylogenetic tree, the protein whose relationship with human ARL-1 was the closest with CHO-Red, next was mouse FR-1, rARLP, MVDP and LeAR. Homologous proteins were found in mouse tissues including vas deferens, testis, bladder and uterus by Western blotting using polyclonal antibodies against ARL-1 protein from domestic rabbits.


CONCLUSIONS
CHO-Red has the highest homology, the shortest genetic distance and the closest relationship with human ARL-1, next is FR-1, rARLP, MVDP. The major distribution of mouse ARL-1 homologous proteins is in vas deferens, testis, bladder and uterus, deducing they might be CHO-Red, FR-1, rARLP or MVDP
