Abstract

The brain tumor glioblastoma (GBM) remains one of the most aggressive and devastating tumors despite decades of effort to find more effective treatments. A hallmark of GBM is the constitutive activation of the nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappaB) signaling pathway, which regulates cell proliferation, inflammation, migration and apoptosis. The prolyl isomerase, Pin1, has been found to bind directly to the NF-kappaB protein, p65, and cause increases in NF-kappaB promoter activity in a breast cancer model. We now present evidence that this interaction occurs in GBM and that it has important consequences on NF-kappaB signaling. We demonstrate that Pin1 levels are enhanced in primary GBM tissues compared with controls, and that this difference in Pin1 expression affects the migratory capacity of GBM-derived cells. Pin1 knockdown decreases the amount of activated, phosphorylated p65 in the nucleus, resulting in inhibition of the transcriptional program of the IL-8 gene. Through the use of microarray, we also observed changes in the expression levels of other NF-kappaB regulated genes due to Pin1 knockdown. Taken together, these data suggest that Pin1 is an important regulator of NF-kappaB in GBM, and support the notion of using Pin1 as a therapeutic target in the future.

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.
