Abstract There is a relationship between person’s diet and the development prevention of some cancers. Carotenoids are found as various natural pigments in many fruits vegetables. Studies on carotenoids their potential roles carcinogenesis increasing importance day by day. In this study, we aimed to determine cytotoxic genotoxic effects capsanthin, carotenoid compound, human prostate cancer cel...

Osteoblastic metastases are common in lethal prostate cancer. Effective therapy for bone metastases is lacking. Thus, developing an appropriate in vitro screening system is critical to prioritize which of the newly developed agents should undergo additional expensive and time-consuming in vivo evaluation in bone metastases animal models. In the past, such in vitro screening evaluated the respon...

Our laboratory has previously reported on the derivation of LNCaP cell sublines from LNCaP tumors maintained in castrated and intact athymic male mice. These LNCaP sublines differ from the parental line in tumorigenicity and androgen dependence. This paper demonstrates that one of these sublines acquired metastatic potential. When inoculated either s.c. or orthotopically, the C4-2 subline metas...

Androgen receptor (AR) signaling is important for prostate cancer (PCa) cell proliferation. Here, we showed that proliferation of hormone-sensitive prostate cancer cells such as LNCaP was significantly enhanced by testosterone stimulation whereas hormone-insensitive prostate cancer cells such as PC3 and VCaP did not respond to testosterone stimulation. Blocking of AR using bicalutamide abolishe...

Background . Melittin is a major constituent of honeybee venom and comprises water-soluble surfactant peptide with cytolytic effects potentially applicable in anticancer therapy. We evaluated the impact melittin from Bashkir ( Apis mellifera L.) on cell viability various prostate cancer lineages. Materials methods. MTT assays index estimation were used to evaluate effect proliferation various-g...

Antiproliferative protein (APP) isolated from conditioned media of two androgen-independent prostatic carcinoma cell lines, PC3 and Du-145 was shown to inhibit selectively cell proliferation of androgen-dependent prostate cancer cell line LNCaP in a dose dependent manner. This protein was further purified with HPLC using hydrophobic interaction column (phenyl 5PW) and was used to study the modu...

Background: Prostate cancer is the second most common cancer in men worldwide and the third most common cancer in Iranian men. Chemotherapy is used to treat this cancer, but it has toxic effect. Natural compounds found in marine organisms and plants have anticancer considered. The aim of the present study was to investigate the effect of crab shell extract on induction of apoptosis in prostate ...

Differential gene expression between androgen-dependent (LNCaP-FGC) and androgen-independent (LNCaP-LNO) prostate cancer cells has been investigated using RNA arbitrarily primed and differential display PCR of mRNA. Four differentially expressed cDNA transcripts were identified, of which differential expression was confirmed by Northern blot analysis. Sequence analysis revealed two unknown (JC1...

Increased expression of IFI16 protein (encoded by the IFI16 gene) in normal human prostate epithelial cells is associated with cellular senescence-associated cell growth arrest. Consistent with a role for IFI16 protein in cellular senescence, the expression of IFI16 protein is either very low or not detectable in human prostate cancer cell lines. We now report that treatment of DU-145 and LNCaP...

Chemokines and their receptors have key roles in cancer progression. The present study investigated chemokine activity in the prostate cancer bone metastasis microenvironment. Growth and migration of human prostate cancer cells were assayed in cocultures with bone stromal cells. The migration of LNCaP cells significantly increased when co-cultured with bone stromal cells isolated from prostate ...
