Functional significance of secreted Frizzled-related protein 1 in metastatic renal cell carcinomas.
The secreted Frizzled-related protein 1 (SFRP1) is a Wingless-type (Wnt) antagonist that has been associated with various malignancies, including renal cell carcinomas (RCC). However, the functional significance of SFRP1 has never been investigated in metastatic RCC. Here, we investigated the role of this molecule in kidney cancer progression and metastasis. Using Wnt pathway-focused cDNA expre...
متن کاملSecreted frizzled-related protein 1 loss contributes to tumor phenotype of clear cell renal cell carcinoma.
PURPOSE Incidence and mortality rates for renal cell carcinoma (RCC) have been rising for decades. Unfortunately, the molecular events that support RCC carcinogenesis remain poorly understood. In an effort to gain a better understanding of signaling events in clear cell RCC (cRCC), we investigated the antitumor activity of secreted frizzled-related protein 1 (sFRP1), a negative regulator of Wnt...
متن کاملRole of secreted frizzled-related protein 3 in human renal cell carcinoma.
The secreted frizzled-related protein (sFRP) family plays an important role in the inhibition of the Wnt signaling pathway in various cancers. The functional significance of Wnt antagonist sFRP3 has not been investigated in renal cancer. We performed tissue microarray and found that the level of sFRP3 protein was high in normal kidney, low in primary renal cancer tissues, and high in metastatic...
متن کاملLoss of secreted frizzled-related protein-1 expression in renal cell carcinoma reveals a critical tumor suppressor function.
In this issue of Clinical Cancer Research , Gumz et al. report on the loss of secreted frizzled-related protein-1 (sFRP-1) in clear cell renal cell carcinoma (RCC; ref. 1). sFRP-1 is a member of a family of proteins that bind Wnts and can inhibit Wnt signaling during embryonic development and in the adult homeostasis (2, 3). Inappropriate Wnt signaling is a well-established mechanism of oncogen...
متن کاملOncogenic functions of secreted Frizzled-related protein 2 in human renal cancer.
The secreted Frizzled-related proteins (sFRP) are modulators of the Wnt signaling pathway, which is involved in embryonic development and tumor progression. The functions of sFRP2 have not been studied in renal cancer. Transient transfection of sFRP2 promoted cell growth in renal carcinoma cells, whereby the largest effect was observed in A498 cells. To further study the functions of sFRP2 gene...
