• ♀: phenotype observed in females
• ♂: phenotype observed in males
• N: normal phenotype

cardiovascular system

hypertension ( J:287773 )

• higher systolic and diastolic blood pressure

• hypertension is especially pronounced during the active, awake period

• hydrochlorothiazide (HCTZ) treatment normalizes blood pressure

salt-sensitive hypertension ( J:287773 )

• dietary salt loading exacerbates hypertension

renal/urinary system

decreased urine potassium level ( J:287773 )

• mice exhibit lower rates of urinary potassium excretion and are unable to develop a transtubular potassium gradient, indicating impaired potassium secretion from the aldosterone-sensitive distal nephron

• HCTZ restores urinary potassium excretion and transtubular potassium gradient

abnormal nephron morphology ( J:287773 )

• aldosterone-sensitive distal nephron mass is reduced

• length and area of cortical distal nephron segment DCT1 is increased with a commensurate decrease in the length and area of the CNT segment

• HCTZ treatment reverses the structural nephron remodeling

abnormal kidney physiology ( J:287773 )

• salt-sensitive hypertension with low rein indicates aberrant gain in renal sodium absorption

hematopoietic system

decreased hematocrit ( J:287773 )

homeostasis/metabolism

decreased blood urea nitrogen level ( J:287773 )

• reduction in BUN levels

• HCTZ treatment corrects BUN levels

hyperkalemia ( J:287773 )

• mice exhibit high plasma potassium levels

• a potassium-rich diet exacerbates hyperkalemia

• HCTZ corrects the hyperkalemia

increased circulating chloride level ( J:287773 )

decreased urine potassium level ( J:287773 )

• mice exhibit lower rates of urinary potassium excretion and are unable to develop a transtubular potassium gradient, indicating impaired potassium secretion from the aldosterone-sensitive distal nephron

• HCTZ restores urinary potassium excretion and transtubular potassium gradient

metabolic acidosis ( J:287773 )

decreased renin activity ( J:287773 )

• plasma renin activity is decreased
