| T1 |
0-157 |
Sentence |
denotes |
Targeted oncogenesis reveals a distinct tissue-specific utilization of alternative promoters of the human mineralocorticoid receptor gene in transgenic mice. |
| T2 |
158-366 |
Sentence |
denotes |
The human mineralocorticoid receptor (hMR) is a nuclear receptor mediating aldosterone action, whose expression is driven by two alternative promoters, P1 and P2, flanking the two first 5'-untranslated exons. |
| T3 |
367-537 |
Sentence |
denotes |
In vivo characterization of hMR regulatory regions was performed by targeted oncogenesis in mice using P1 or P2 directing expression of the large T antigen of SV40 (TAg). |
| T4 |
538-716 |
Sentence |
denotes |
While transgenic P1.TAg founders rapidly developed lethal hibernomas from brown fat, cerebral primitive neuroectodermal tumors and facial leiomyosarcomas occurred in P2.TAg mice. |
| T5 |
717-1028 |
Sentence |
denotes |
Quantitative analyses of mouse MR (mMR) and transgene expression indicate that P1 promoter was transcriptionally active in all MR-expressing tissues, directing strong TAg expression in testis and salivary glands, moderate in lung, brain, uterus, liver, and heart but, unlike mMR, rather low in colon and kidney. |
| T6 |
1029-1116 |
Sentence |
denotes |
Importantly, the renal transgene expression colocalized with mMR in the distal nephron. |
| T7 |
1117-1230 |
Sentence |
denotes |
In contrast, P2 promoter was approximately 10 times less potent than P1, with no activity in the brain and colon. |
| T8 |
1231-1339 |
Sentence |
denotes |
Several immortalized cell lines were established from both neoplastic and normal tissues of transgenic mice. |
| T9 |
1340-1528 |
Sentence |
denotes |
These cells exhibited differentiated characteristics and maintained MR expression, thus providing useful models for further studies exploring the widespread expression and functions of MR. |
| T10 |
1529-1705 |
Sentence |
denotes |
Our results demonstrate that hMR gene expression in vivo is controlled by complex regulatory mechanisms involving distinct tissue-specific utilization of alternative promoters. |
