Human Cancer Biology Modeling a Lethal Prostate Cancer Variant with Small-Cell Carcinoma Features
نویسندگان
چکیده
Purpose: Small-cell prostate carcinoma (SCPC) morphology predicts for a distinct clinical behavior, resistance to androgen ablation, and frequent but short responses to chemotherapy. We sought to develop model systems that reflect human SCPC and can improve our understanding of its biology. Experimental Design: We developed a set of castration-resistant prostate carcinomas xenografts and examined their fidelity to their human tumors of origin. We compared the expression and genomic profiles of SCPC and large-cell neuroendocrine carcinoma (LCNEC) xenografts to those of typical prostate adenocarcinoma xenografts. Results were validated immunohistochemically in a panel of 60 human

Clinicopathological Features of Patients with Non-small-cell Lung Cancer in West of Iran
Background: Lung cancer is the most common cause of cancer death worldwide with an annual mortality rate of more than 1.3 million worldwide. We aimed to analyze the clinicopathological features of patients with non-small-cell lung cancer (NSCLC) in west of Iran. Methods: 64 patients with NSCLC who referred to our clinic were analyzed. Sex, age, histopathology, location of the tumor, treatment,...

متن کاملUnderstanding the lethal variant of prostate cancer: power of examining extremes.
Small cell prostate carcinoma is a lethal variant of castration-resistant prostate cancer. Beltran and colleagues identified overexpression and amplification of both aurora kinase A (AURKA) and the MYCN proto-oncogene in the small cell prostate carcinomas and propose Aurora kinase A as a potential therapeutic target in this disease subset.
متن کاملSupernatant Metabolites from Halophilic Archaea to Reduce Tumorigenesis in Prostate Cancer In-vitro and In-vivo
Halophilic archaea are known as the novel producers of natural products and their supernatant metabolites could have cytotoxic effects on cancer cells. In the present study, we screened the anticancer potential of supernatant metabolites from eight native haloarchaeal strains obtained from a culture collection in Iran. Five human cancer cell lines including breast, lung, prostate and also human...
