T1 |
0-79 |
Sentence |
denotes |
Absence of PKC-alpha attenuates lithium-induced nephrogenic diabetes insipidus. |
T2 |
80-182 |
Sentence |
denotes |
Lithium, an effective antipsychotic, induces nephrogenic diabetes insipidus (NDI) in ∼40% of patients. |
T3 |
183-395 |
Sentence |
denotes |
The decreased capacity to concentrate urine is likely due to lithium acutely disrupting the cAMP pathway and chronically reducing urea transporter (UT-A1) and water channel (AQP2) expression in the inner medulla. |
T4 |
396-536 |
Sentence |
denotes |
Targeting an alternative signaling pathway, such as PKC-mediated signaling, may be an effective method of treating lithium-induced polyuria. |
T5 |
537-655 |
Sentence |
denotes |
PKC-alpha null mice (PKCα KO) and strain-matched wild type (WT) controls were treated with lithium for 0, 3 or 5 days. |
T6 |
656-820 |
Sentence |
denotes |
WT mice had increased urine output and lowered urine osmolality after 3 and 5 days of treatment whereas PKCα KO mice had no change in urine output or concentration. |
T7 |
821-976 |
Sentence |
denotes |
Western blot analysis revealed that AQP2 expression in medullary tissues was lowered after 3 and 5 days in WT mice; however, AQP2 was unchanged in PKCα KO. |
T8 |
977-1029 |
Sentence |
denotes |
Similar results were observed with UT-A1 expression. |
T9 |
1030-1081 |
Sentence |
denotes |
Animals were also treated with lithium for 6 weeks. |
T10 |
1082-1205 |
Sentence |
denotes |
Lithium-treated WT mice had 19-fold increased urine output whereas treated PKCα KO animals had a 4-fold increase in output. |
T11 |
1206-1382 |
Sentence |
denotes |
AQP2 and UT-A1 expression was lowered in 6 week lithium-treated WT animals whereas in treated PKCα KO mice, AQP2 was only reduced by 2-fold and UT-A1 expression was unaffected. |
T12 |
1383-1489 |
Sentence |
denotes |
Urinary sodium, potassium and calcium were elevated in lithium-fed WT but not in lithium-fed PKCα KO mice. |
T13 |
1490-1695 |
Sentence |
denotes |
Our data show that ablation of PKCα preserves AQP2 and UT-A1 protein expression and localization in lithium-induced NDI, and prevents the development of the severe polyuria associated with lithium therapy. |
