Prostate cancer (PCa) disease progression is associated with significant changes in intracellular and extracellular proteins, intracellular signaling mechanism, and cancer cell phenotype. These changes may have direct impact on the cellular interactions with nanocarriers; hence, there is the need for a much-detailed understanding, as nanocarrier cellular internalization and intracellular sortin...

Prostate cancer is one of the most common malignancies in men, and it urgently demands precise interventions that target the signaling pathways implicated in its initiation, progression, and metastasis. The Notch-1 signaling pathway is closely associated with the pathophysiology of prostate cancer. This study investigated the antitumor effects and mechanisms of curcumin, which is a well-known n...

OBJECTIVE Despite various therapeutical options in metastatic prostate cancer, the lack of a curative approach motivates further investigations. Treosulfan is an alkylating agent that has proven its indication in the treatment of e.g. ovarian carcinoma. This study focused on the objective of evaluating the effect of in vitro intoxication of human prostate carcinoma cell lines with treosulfan. ...

Transforming growth factor-beta (TGF-β) signaling pathways contain both tumor suppressor and tumor promoting activities. We have demonstrated that Nodal, another member of the TGF-β superfamily, and its receptors are expressed in prostate cancer cells. Nodal and TGF-β exerted similar biological effects on prostate cells; both inhibited proliferation in WPE, RWPE1 and DU145 cells, whereas neithe...

PURPOSE Although microarray technology has been widely adopted by the scientific community, analysis of the ensuing data remains challenging. In this article, we present our experience with a complex design microarray experiment on resistance mechanisms of histone deacetylase inhibitors (HDACI). EXPERIMENTAL DESIGN To improve our understanding of the underlying mechanism of HDACI resistance i...

Histone deacetylase (HDAC) inhibitors are emerging as potent anticancer agents due to their ability to induce apoptosis in various cancer cells, including prostate cancer cells. In the present study, we synthesized a novel HDAC inhibitor, A248, and investigated its apoptotic activity and molecular target in the DU145 and PC3 human prostate cancer cell lines. A248 inhibited the growth of DU145 a...

Cell- and receptor-specific regulation of cell migration by Gi/oα-proteins remains unknown in prostate cancer cells. In the present study, oxytocin (OXT) receptor was detected at the protein level in total cell lysates from C81 (an androgen-independent subline of LNCaP), DU145 and PC3 prostate cancer cells, but not in immortalized normal prostate luminal epithelial cells (RWPE1), and OXT-induce...

BACKGROUND Consumption of lycopene through tomato products has been suggested to reduce the risk of prostate cancer. Cellular adhesion and migration are important features of cancer progression and therefore a potential target for cancer interception. In the present study we have examined the in vitro effect of lycopene on these processes. METHODS Prostate cancer cell lines PC3, DU145 and imm...
