| T1 |
0-112 |
Sentence |
denotes |
Angiotensin II subtype 1a receptor signaling in resident hepatic macrophages induces liver metastasis formation. |
| T2 |
113-196 |
Sentence |
denotes |
Liver metastases from colorectal cancer (CRC) are a clinically significant problem. |
| T3 |
197-269 |
Sentence |
denotes |
The renin-angiotensin system is involved in tumor growth and metastases. |
| T4 |
270-404 |
Sentence |
denotes |
This study was designed to evaluate the role of angiotensin II subtype receptor 1a (AT1a) in the formation of liver metastasis in CRC. |
| T5 |
405-571 |
Sentence |
denotes |
A model of liver metastasis was developed by intrasplenic injection of mouse colon cancer (CMT-93) into AT1a knockout mice (AT1aKO) and wild-type (C57BL/6) mice (WT). |
| T6 |
572-673 |
Sentence |
denotes |
Compared with WT mice, the liver weight and liver metastatic rate were significantly lower in AT1aKO. |
| T7 |
674-793 |
Sentence |
denotes |
The mRNA levels of CD31, transforming growth factor- β1 (TGF-β1), and F4/80 were suppressed in AT1aKO compared with WT. |
| T8 |
794-952 |
Sentence |
denotes |
Double immunofluorescence analysis showed that the number of accumulated F4/80(+) cells expressing TGF-β1 in metastatic areas was higher in WT than in AT1aKO. |
| T9 |
953-1067 |
Sentence |
denotes |
The AT1aKO bone marrow (BM) (AT1aKO-BM)→WT showed suppressed formation of liver metastasis compared with WT-BM→WT. |
| T10 |
1068-1171 |
Sentence |
denotes |
However, the formation of metastasis was further suppressed in WT-BM→AT1aKO compared with AT1aKO-BM→WT. |
| T11 |
1172-1383 |
Sentence |
denotes |
In addition, accumulated F4/80(+) cells in the liver metastasis were not BM-derived F4/80(+) cells, but mainly resident hepatic F4/80(+) cells, and these resident hepatic F4/80(+) cells were positive for TGF-β1. |
| T12 |
1384-1443 |
Sentence |
denotes |
Angiotensin II enhanced TGF-β1 expression in Kupffer cells. |
| T13 |
1444-1567 |
Sentence |
denotes |
Treatment of WT with clodronate liposomes suppressed liver metastasis by diminishing TGF-β1(+) F4/80(+) cells accumulation. |
| T14 |
1568-1700 |
Sentence |
denotes |
The formation of liver metastasis correlated with collagen deposition in the metastatic area, which was dependent on AT1a signaling. |
| T15 |
1701-1840 |
Sentence |
denotes |
These results suggested that resident hepatic macrophages induced liver metastasis formation by induction of TGF-β1 through AT1a signaling. |
