denotes |
OBJECTIVE: |
TextSentencer_T3 |
100-218 |
Sentence |
denotes |
The canonical Wnt/β-catenin pathway was recently identified as a factor in the pathogenesis of several renal diseases. |
TextSentencer_T4 |
219-344 |
Sentence |
denotes |
The aim of this study was to evaluate Wnt signaling activity during disease development in a murine model of lupus nephritis. |

345-353 |
Sentence |
denotes |
METHODS: |
TextSentencer_T6 |
354-497 |
Sentence |
denotes |
Wnt activity and Dkk-1 expression were serially assayed in the serum and kidneys of (NZB × NZW)F(1) mice during progression of lupus nephritis. |
TextSentencer_T7 |
498-636 |
Sentence |
denotes |
The effects of serum obtained from mice with lupus and serum-equivalent concentrations of Dkk-1 on mesangial cells were assessed in vitro. |
TextSentencer_T8 |
637-645 |
Sentence |
denotes |
RESULTS: |
TextSentencer_T9 |
646-850 |
Sentence |
denotes |
Gene expression analyses revealed increased canonical Wnt pathway activity in kidneys during development of lupus nephritis, paralleled by an increase in renal and serum levels of the Wnt inhibitor Dkk-1. |
TextSentencer_T10 |
851-955 |
Sentence |
denotes |
Sera obtained from proteinuric-stage (NZB × NZW)F(1) mice showed strong Wnt-inhibitory effects in vitro. |
TextSentencer_T11 |
956-1208 |
Sentence |
denotes |
Dkk-1 concentrations comparable to those observed in lupus-prone mice induced apoptosis in tubular and mesangial cells in vitro, whereas no such effect was seen for the range of concentrations observed in young prediseased mice and control BALB/c mice. |

1209-1220 |
Sentence |
denotes |
CONCLUSION: |
TextSentencer_T13 |
1221-1369 |
Sentence |
denotes |
These data demonstrate that renal Wnt signaling activity is increased in lupus and is accompanied by an increase in renal and serum levels of Dkk-1. |
TextSentencer_T14 |
1370-1583 |
Sentence |
denotes |
The Wnt pathway is involved in the turnover of extracellular matrix constituents and represents a potential mediator of the morphologic changes that occur within the glomerulus during the development of nephritis. |
TextSentencer_T15 |
1584-1845 |
Sentence |
denotes |
Furthermore, increased levels of Dkk-1 serve as a potential proapoptotic stimulus in vitro and possibly in vivo and could be an important element in the initiation and progression of systemic and end-organ disease manifestations in systemic lupus erythematosus. |
