Anterior Gradient Protein (AGR-2) is reported to be over-expressed in many epithelial cancers and promotes metastasis. A clear-cut mechanism for its observed function(s) has not been previously identified. We found significant upregulation of AGR-2 expression in a bone metastatic prostate cancer cell line, PC3, following culturing in bone marrow-conditioned medium. Substantial AGR-2 expression ...

UNLABELLED The bone is a preferred site for metastatic homing of prostate cancer cells. Once prostate cancer patients develop skeletal metastases, they eventually succumb to the disease; therefore, it is imperative to identify key molecular drivers of this process. This study examines the involvement of protein kinase C epsilon (PKCε), an oncogenic protein that is abnormally overexpressed in hu...

Curcumin (Cur) has been found to be very efficacious against many different types of cancer cells. However, the major disadvantage associated with the use of Cur is its low systemic bioavailability. Our present work investigated the toxic effect of encapsulation of Cur in PLGA (poly lactic-coglycolic acid) nanospheres (NCur) on PC3 human cancer prostate cell. In the present study, we have inves...

Despite extensive research, the mechanisms for propagation of Pc3–4 energy from the generation region at the bow shock to the high-latitude ionosphere remain unresolved. We used high temporal (6–12 s) and spatial (45 km) resolution data from the SuperDARN TIGER radar (Tasmania) to examine Pc3–4 wave signatures at the F-region heights. We focus on a case study on 28 September 2000, when large-am...

Mefloquine (MQ) is currently in clinical use as a prophylactic treatment for malaria. Previous studies have shown that MQ induces oxidative stress in vitro. The present study investigated the anticancer effects of MQ treatment in PC3 cells. The cell viability was evaluated using sulphorhodamine-B (SRB) staining, while annexin V and propidium iodide (PI) were used as an assay for cell death. Rea...

The aim of this study was to investigate the effect of molds on levels of low molecular mass thiols in grasses. For this purpose, the three grass species Lolium perenne, Festulolium pabulare and Festulolium braunii were cultivated and sampled during four months, from June to September. The same species were also grown under controlled conditions. High-performance liquid chromatography with elec...

Gleditsia sinensis thorns (GST) have been used as a traditional medicine for carbuncles and skin diseases. The purpose of this study was to decide whether non-toxicological levels of water extract of GST (WEGST) are effective in inhibiting the progress of prostate cancer formation and to identify the target molecule involved in the WEGST-mediated inhibitory process of prostate cancer cell migra...

The goal of this research was to characterize ADI isolated from Lactobacillus sp. and test its anticancer activity in vitro. Because the arginine-degrading enzyme is a strong agent, it two phases clinical isolate: 70% saturated ammonium sulphate precipitation followed by gel filtration chromatography (2x35cm). most active fractions (7.3 U/ ml), Purified had special action (48.6 U/mg) with nine ...

Cystatin C is believed to prevent tumor progression by inhibiting the activities of a family of lysosomal cysteine proteases. However, little is known about the precise mechanism of cystatin C function in prostate cancer. In the present study, we examined the expression of cystatin C and its association with matrix metalloproteinases 2 (MMP2) and androgen receptor (AR) in a tissue microarray co...

The androgen receptor (AR) mediates the developmental, physiologic, and pathologic effects of androgens including 5α-dihydrotestosterone (DHT). However, the mechanisms whereby AR regulates growth suppression and differentiation of luminal epithelial cells in the prostate gland and proliferation of malignant versions of these cells are not well understood, though they are central to prostate dev...
