| Abstract: | AIM:Aquaporins (AQP) are very important for the water transport across cell membrane. There are at least 10 mammalian AQPs( aquaporins 0-9) distributed in various organs and different kinds of cells. Each AQP has a distinct organ distribution, and this distribution could be useful in presuming the biological function of the aquaporin. The aim of this study was to figure out the distribution of aquaporin 7 (AQP7) and aquaporin 8(AQP8).METHODS：Semi-quantified RT-PCR was employed in this research. The ratio of OD value of target gene products divided by which of control gene products was calculated. Among 35 organs, testis, epididymis, skin, muscle, rectum, lung, bronchus, lymph node, stomach, duodenum, jejunum, ileum, colon, pancreas, liver, gall bladder, spleen, mammary gland, uterus, placenta, tonsil, urinary bladder, thyroid came from normal area of removed samples during operation. cDNA library of Prostate, thymus, salivary gland, penis, carotiol artery, adrenal gland, occipital lobe of brain, temporal lobe of brain, frontal lobe of brain, parietal lobe of brain, mid brain, choroid plexus are purchased from OriGene biotechnique company.RESULTS：①AQP 7 mRNA was found in testis, muscle, gall bladder, carotiol artery, lymph node and adrenal gland, and maximum expression of AQP 7 was in testis.②AQP 8 mRNA was found in pancreas, testis, skin and colon. and maximum expression of AQP 8 was in pancreas.CONCLUSION:Coexistence of AQP 7 and 8 in testis was confirmed, which suggested that both of these two aquaporins were involved in the regulation of testis function. |
