Extracts from the seeds of milk thistle, Silybum marianum , are known commonly as silibinin and silymarin and possess anticancer actions on human prostate carcinoma in vitro and in vivo. Seven distinct flavonolignan compounds and a flavonoid have been isolated from commercial silymarin extracts. Most notably, two pairs of diastereomers, silybin A and silybin B and isosilybin A and isosilybin B,...

The discovery of rare subpopulations of cancer stem cells (CSCs) has created a new focus in cancer research. As CSCs demonstrate resistance to chemoradiation therapy relative to other cancer cells, this allows the enrichment of CSC populations by killing apoptosis-susceptible cancer cells. In this study, three commonly used human prostate cancer (PCa) cell lines (DU145, PC-3 and LNCaP) were exa...

Cdk5 is a small serine/threonine protein kinase which belongs to Cdk family. Unlike other Cdk members, Cdk5 is known to be irrelevant in cell cycle so far. Cdk5 kinase activity is regulated by binding with its activator, p35. Our previous results indicate that Cdk5 and p35 are involved in drugs-induced apoptosis of prostate cancer cells. Retinoic acid (RA) is one of vitamin A-related compounds....

The present study was undertaken to compare the relationship between response to exogenous epidermal growth factor (EGF) and the expression of the EGF-receptor (EGF-R) in an androgen sensitive (LNCaP) and insensitive (DU145) prostate cancer cell line. Although both cell lines demonstrated a single EGF-R binding site of similar high affinities (mean dissociation constant (Kd) ± S.D. for DU145 = ...

microRNA‑99a (miR‑99a) was reported to be among the most frequently downregulated miRNAs in numerous types of human cancers, including prostate, bladder, hepatocellular and ovarian carcinoma, squamous cell carcinoma of the tongue, squamous cell lung carcinoma as well as childhood adrenocortical tumors. The aim of the present study was to determine the effects of miRNA‑99a on cell proliferation,...

Abstract Background About 90% of cancer-related deaths are due to metastasis cancer cells, and angiogenesis is a critical step in this process. sFLT01 novel fusion protein dual-targeting agent that neutralizes both VEGF PlGF proangiogenic activities. GRP78 dual effect tumor growth could be activated under stimulation. The current study was designed investigate the inhibitory impact on VEGF/GRP7...

The prostate specific antigen (PSA) promoter/enhancer has been clearly demonstrated to be tissue specific, and has been applied to prostate-specific gene therapy. However, the transcription of the PSA gene is strictly androgen dependent, and its promoter activity is very weak at low concentrations of testosterone, which are generally observed in prostatic cancer patients treated with androgen d...
