1. A method of modulating the aquaporin channel in a mammal, which consists in administering relaxin in an amount effective to modify the expression of aquaporin in mammalian tissue. The method of claim 1, wherein the expression of aquaporin is the expression of the aquaporin gene. The method according to claim 2, in which the increasing expression of the aquaporin gene is carried out. The method of claim 2, wherein the down-regulation of the aquaporin gene is carried out. The method of claim 1, wherein the expression of aquaporin is the expression of the aquaporin protein. The method according to claim 5, in which the increasing expression of the aquaporin protein is carried out. The method according to claim 5, wherein the aquaporin protein is down-regulated. The method of claim 1, wherein the aquaporin channel is selected from the group consisting of aquaporin-0 (AQP0), aquaporin-1 (AQP1), aquaporin-2 (AQP2), aquaporin-3 (AQP3), aquaporin-4 (AQP4), aquaporin-5 (AQP5), aquaporin-6 (AQP6), aquaporin-7 (AQP7), aquaporin-8 (AQP8), aquaporin-9 (AQP9) and aquaporin-10 (AQP10) .9. The method of claim 8, wherein the aquaporin channel is selected from the group consisting of aquaporin-1 (AQP1), aquaporin-2 (AQP2), aquaporin-3 (AQP3), aquaporin-4 (AQP4) and aquaporin-5 (AQP5). ten.
