We describe an in vitro model for prostate cancer treatment that suggests a potential benefit for combined androgen ablation and cytotoxic chemotherapy. Androgen treatment of the LNCaP hormone-dependent human prostate cancer cell line induces increased expression of the BCL-2 protein. Increased levels of this protein are known to mediate inhibition of apoptosis. LNCaP cells, however, did not un...

BACKGROUND The main objective was to evaluate the possible protective effect of Chuquiraga spinosa extract on N-methyl nitrosourea (NMU)-induced prostate cancer in rats and DU-145 cell line. MATERIALS AND METHODS Prostate carcinogenesis was induced in 30 male Holtzman rats by providing cyproterone acetate, testosterone, and NMU. The tumors were monitored and hematological and biochemical para...

the tp53 gene is one of the most frequently mutated genes amongst human malignancies, particularly tp53 codon 72 polymorphism. furthermore, an association between the tp53 codon 72 variants and prostate cancer has been reported in several studies. although some studies have indicated an association between the tp53 arg/arg variant and an increased risk for prostate cancer, other studies have sh...

OBJECTIVE In recent years, the field of cancer immunotherapy has become a research hotspot and is currently faced with numerous challenges. The objective of this study was to assess the success of cbl-b gene silencing in splenic T lymphocytes as an immune strategy to target the murine prostate cancer RM-1 cells in vitro and solid tumors in vivo. MATERIALS AND METHODS For this purpose, cbl-b g...

Androgen ablation has been an effective treatment in patients with advanced prostate cancer. However, most treated patients develop hormonally resistant disease and do not respond to conventional chemotherapy. Immunotherapy against prostate cancer is an alternative approach in overcoming hormonal/drug-resistant prostate cancer. Cytotoxic immune lymphocytes kill target cells via the perforin/gra...

INTRODUCTION: Curcuminoids and Oleic acid, reported in the literature as antioxidant antitumor agents, were combined nanoemulsion, using Pluronic F127 a stabilizer.
 METHODS: The main objective is to investigate its cytotoxic activity against cancer cells.
 RESULTS AND DISCUSSION: nanoemulsion show values of particle size (251.4 ± 4.6 nm), zeta potential (-34.8 1.0 mV), pH (4.8) class...

Background: Prostate cancer is the second form of cancer among men worldwide. For early cancer detection, we should identify tumors in initial stages before the physical signs become visible. The present study aims to evaluate the diagnostic value of cell-free DNA (cfDNA), its comparison with prostate-specific antigen (PSA) level in prostate cancer screening and also in patients with localized ...

Prostate cancer is the most common type of cancer diagnosed and the second leading cause of cancer-related death in American men. Natural Killer (NK) cells are the first line of defense against cancer and infections. NK cell function is regulated by a delicate balance between signals received through activating and inhibitory receptors. Previously, we identified Lectin-like transcript-1 (LLT1/O...

Background: Prostate cancer is the most common malignancy in men and the second leading cause of death in all countries of the world. The exact mechanism of prostate cancer is not known. On the other hand, early detection of prostate cancer can lead to a complete cure. Several clinical experiments including Digital Rectum Examination (DRE), biochemistry such as Prostate Specific Antigen (PSA), ...
