many cell lines, when cultured under proper conditions, can form three dimensionalstructures called multicellular spheroids. these spheroids resemble in vivo tumor models in severalaspects. therefore, studying growth characteristics and behavior of spheroids is beneficial inunderstanding the behavior of tumors under various experimental conditions. in this work, we havestudied the growth proper...

BACKGROUND Hypoacetylation on histone H3 of human prostate cancer cells has been described. Little is known about the modifications of other histones from prostate cancer cells. METHODS Histones were isolated from the prostate cancer cell line DU-145 and the non-malignant prostatic cell line RC170N/h. Post-translational modifications of histone H2B were determined by liquid chromatography-mas...

Background: It is now well-demonstrated that histone demethylases play an important role in developmental controls, cell-fate decisions, and a variety of diseases such as cancer. Lysine-specific demethylase 5D (KDM5D) is a male-specific histone demethylase that specifically demethylates di- and tri-methyl H3K4 at the start site of active genes. In this light, the aim of this study was to invest...

Uteroglobin (UG) is a potent immunomodulatory and antiinflammatory secretory protein with high levels detected in human prostate tissue. We used three human prostate cancer cell lines (DU-145, PC3-M, and LNCaP) to test the hypothesis that UG may modulate invasiveness of prostatic carcinoma cells in the Boyden chamber assay for invasion through a reconstituted basement membrane preparation. Fibr...

We previously reported that androgen receptor (AR) plays a role in the regulation of adhesion to the extracellular matrix and invasion of human prostate cancer cells by influencing the expression of specific integrin subunits. It is now considered that chemokines play a significant role in organ-selective cancer metastasis. In this study, we hypothesized that AR may influence the expression of ...

Mutagenic oxidative DNA base damage increases with age in prostatic tissue. Various factors may influence this increase including: increased production of reactive oxygen species, increased susceptibility to oxidative stress, alterations in detoxifying enzyme levels or defects in DNA repair. Using liquid chromatography/mass spectrometry and gas chromatography/mass spectrometry, we show increase...
