Abstract

Cysteine‐rich 61 (Cyr61) is a member of the CCN protein family that has been implicated in diverse biological processes such as cell adhesion, proliferation, angiogenesis, and tumorigenesis. Altered expression of Cyr61 is found to be associated with human cancers. Here we show that Cyr61 was up‐regulated in prostate cancer cell lines and tumor tissues. A significant correlation of Cyr61 expression was found between benign prostatic hyperplasia and prostate cancer ( P = 0.002). However, there was no significant correlation between levels of PSA and Cyr61 expression ( P = 0.2). Cyr61 may represent an independent prostate cancer biomarker and potentially a useful therapeutic target for prostate cancer treatment. In addition, our analysis based on published data and data present in this report indicted that levels of Cyr61 expression associated with the status of the tumor suppressor gene p53 in 32 cancer cell lines analyzed, high levels of Cyr61 expression were found in cell lines with mutant or null p53 gene, whereas lower expression levels of Cyr61 in the cell lines with wild‐type p53 . We further show that over‐expression of dominant negative p53 or down‐expression of endogenous wild‐type p53 resulted in up‐regulation of Cyr61 expression, suggesting a functional link between Cyr61 and p53 in cancers.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • High levels of CCN1 expression are found in prostate cancer cell lines with mutant or null p53, while lower levels are found in cells expressing wild-type p53.

    “Interestingly, high levels of CCN1 expression are found in prostate cancer cell lines with a mutant or null p53 gene, but lower levels are found in cells expressing wild-type p53 [156].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
