15545300 Jaruga-Killeen E, Rayford W: TNF receptor 1 is involved in the induction of apoptosis by the cyclin dependent kinase inhibitor p27Kip1 in the prostate cancer cell line PC-3. FASEB J. 2005 Jan;19(1):139-41. Epub 2004 Nov 15.

Cell cycle and typical markers of apoptosis were analyzed by flow cytometry in the presence of the following reagents: cycloheximide, pan-caspase inhibitor ZVAD-fmk, neutralizing anti-TNFR1, and anti-TNFR2.

METHODS: We used immunoprecipitation with K-cyclin antibodies to examine the association of K-cyclin with cdk2, cdk6, p21Cip1, and p27Kip1 proteins in BC3 cells.
The half-life of K-cyclin and cyclin D2 proteins was determined by blocking protein synthesis with cycloheximide and measuring proteins in cell lysates by western blot analysis.

Here, we show that E6-AP interacts with and promotes proteasome-mediated degradation of cyclin-dependent kinase inhibitor p27.

However, we found that in its early stages the UPR leads to a transient inhibition of proteasomal disposal of cytosolic substrates (p53 and p27kip1) and of those targeted to ER (endoplasmic reticulum)-associated degradation (uncleaved precursor of asialoglycoprotein receptor H2a).

Other p53-related genes including p21WAF1, p27Kip1, MDM-2, and the p16INK4a alternate reading frame (ARF) sequence showed similar patterns of differential mRNA expression.

INTRODUCTION: Loss of the cyclin-dependent kinase inhibitor p27 is associated with poor prognosis in breast cancer.
The effect of rapamycin on the degradation rate of Skp2 expression was examined in cycloheximide-treated cells and in relationship to the anaphase promoting complex/Cdh1 (APC\C) inhibitor Emi1.
