Abstract:
Brattleboro diabetes insipidus mutant rats and normal WAG rats were subjected to water loading or thirst during 3 days. It was found that tropomyosin-encoding gene expression has a tissue-specific pattern in the kidney. Northern blot and western blot analysis had shown that the main expression of Tpm3(3) takes place in the renal medulla, and its intensity differs in normal and mutant rats. The differences between mutants with an ineffective vasopressin synthesizing system and the rats having an intact vasopressin gene were more distinct under long-lasting dehydration. The ratio between renal medullary tropomyosin of Brattleboro and WAG lines of rats was 39.76 +/- 0.90 versus 18.29 +/- 0.86 under water loading, and 46.12 +/- 2.14 versus 13.83 +/- 0.66 in thirst.

Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
