Besides, p16 methylation was not linked to clinical stage, prostate-specific antigen (PSA) level, and Gleason score (GS) of patients with PCa. p14 methylation was not correlated with PCa in tissue and urine samples.
We established a prostate cancer epithelial cell line (PC-3 TO-A8/A9) expressing S100A8 and S100A9 simultaneously under doxycycline control, to study the role of S100A8/A9 on tumor growth and infiltration of immune cells in subcutaneous xenografts in male NMRI nu/nu mice.
We and others previously reported that p14 alternative reading frame (ARF) expression is positively correlated with the disease progression and severity of PCa.
By using multidisciplinary analysis of corpora amylacea inclusions in prostate glands of patients diagnosed with prostate cancer we have revealed that their major components are the amyloid forms of S100A8 and S100A9 proteins associated with numerous inflammatory conditions and types of cancer.
To investigate potential functional implications of S100A8 and S100A9 in prostate cancer, we examined the influence of over-expressed and of purified recombinant S100A8 and S100A9 proteins in different prostate epithelial cell lines.
