The majority of prostate cancer (PCa) patient receiving androgen ablation therapy eventually develop castration-resistant prostate cancer (CRPC). We previously reported that androgen treatment suppresses Skp2 and c-Myc through androgen receptor (AR) and induced G1 cell cycle arrest in androgen-independent LNCaP 104-R2 cells, a late stage CRPC cell line model. However, the mechanism of androgeni...
OBJECTIVES This study examined effects of 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase inhibitor cerivastatin on human saphenous vein (SV), endothelial cells (EC) and smooth muscle cells (SMC). BACKGROUND Venous bypass graft failure involves EC dysfunction and SMC proliferation. Substances that improve EC function and inhibit SMC proliferation would be of clinical relevance. METHODS B...
Cytoplasmic mislocalization of p27 and cdk2 mediates the anti-migratory and anti1 proliferative effects of Nodal in human trophoblast cells 2 3 Lubna Nadeem, Jelena Brkic, Yangchun Frank Chen, Tung Bui, Sadia Munir and Chun Peng 4 Department of Biology, York University, Toronto, Canada 5 6 7 Running title: p27 and cdk2 mediate Nodal actions 8
The activation of DNA replication appears to involve at least four steps. These include origin recognition, origin unwinding, primer synthesis, and a switching step to a continuous elongation mode. Moreover, in higher eukaryotes a number of studies have shown that much of the DNA replication which occurs is restricted to specific sites within the nuclei. It has been proposed that these replicat...
Proliferation of some cultured human tumor cell lines bearing high numbers of epidermal growth factor (EGF) receptors is paradoxically inhibited by EGF in nanomolar concentrations. In the present study, we have investigated the biochemical mechanism of growth inhibition in A431 human squamous carcinoma cells exposed to exogenous EGF. In parallel, we studied a selected subpopulation, A431-F, whi...
DOC-1R (deleted in oral cancer-1 related) is a novel putative tumor suppressor. This study investigated DOC-1R antitumor activity and the underlying molecular mechanisms. Cell phenotypes were assessed using flow cytometry, BrdU incorporation and CDK2 kinase assays in DOC-1R overexpressing HeLa cells. In addition, RT-PCR and Western blot assays were used to detect underlying molecular changes in...
Cyclin E/Cdk2 is a key regulator in G(1)-S transition. We have identified a novel cyclin E/Cdk2 substrate called Ankrd17 (ankyrin repeat protein 17) using the TAP tag purification technique. Ankrd17 protein contains two clusters of a total 25 ankyrin repeats at its N terminus, one NES (nuclear exporting signal) and one NLS (nuclear localization signal) in the middle, and one RXL motif at its C ...
Cyclin-dependent kinases are most extensively studied targets for cancer chemotherapy since the tumor cells exhibit false checkpoints and can proliferate even if the genome is compromised. Cyclin-dependent kinases ensure the tight regulation of the cell cycle execution by mediating phosphorylation of cellular proteins. Deregulation of the cyclin-dependent kinase 2 activity by cellular and exter...
Cyclin-dependent kinase 2 (CDK2), a member of Cyclin-dependent kinases (CDKs), plays an important role in cell division and DNA replication. It is regarded as a desired target to treat cancer and tumor by interrupting aberrant cell proliferation. Compared to lower subtype selectivity of CDK2 ATP-competitive inhibitors, CDK2 allosteric inhibitor with higher subtype selectivity has been used to t...
TDP43 is ubiquitously expressed in human tissues and plays a crucial role in a wide range of neurodegenerative diseases. However, the study in cancer especially in cervical cancer is less known. The aim of this study is to identify the expression and function of TDP43 in cervical cancer. Here we reported that protein and mRNA level of TDP43 expression was up-regulated in cervical cancer tissues...
