Androgens Regulate SMAD Ubiquitination Regulatory Factor-1 Expression and Prostate Cancer Cell Invasion Abstract #1033

Introduction: Prostate cancer is the most commonly diagnosed male cancer and is a hormone-driven disease. Androgens have been recognized as a major promoter of PCa development and progression. However, the mechanism of androgen action in PCa, especially in PCa cell invasion remains largely unclear. SMAD ubiquitination regulatory factor-1 (SMURF1) is a C2-WW-HECT-domain E3 ubiquitin ligase that plays important roles in cancer cell metastasis. Whether there is a relationship between androgens and SMURF1 express is not known.
Aim(s): Identification of novel therapeutic targets for treatment of advanced PCa.
Materials and methods: The effect of androgens on the expression of SMURF1 in PCa cell lines was examined by Western blot and RT-PCR. The binding of AR to the SMURF1 gene enhancer was determined by chromatin immunoprecipitation (ChIP) assay, CHIP-Seq and RNA-Seq analysis. Cell migration and invasion was measured by wound healing and Matrigel invasion assays, respectively.

#19 Antitumor activity of Pasireotide (SOM230) alone and in combination with Everolimus (RAD001) in DU-145 human prostate cancer model
Introduction: Pasireotide (SOM230) is a novel multi-receptor ligand somatostatin analogue with high affinity for somatostatin receptor subtypes sst1,2,3 and sst5. Like octreotide, which binds primarily to sst2, it inhibits hypersecretion of hormones from patients with functional pituitary tumors and gastroenteropancreatic neuroendocrine (GEP/NET) tumors. In addition, tumor shrinkage has been observed with both compounds in patients with acromegaly, Cushing’s disease and GEP/NETs, but its tumor-reducing mechanism of action has so far not been revealed. In patients with breast and liver cancer, octreotide had little or no antitumor activity.

#1243 Neuroendocrine Carcinomas of the Prostate
Introduction: Since focal neuroendocrine (NE) differentiation in prostate carcinomas represents a frequent phenomenon when NE markers are used for documentation, NE carcinomas are extremely rare form of highly aggressive prostate tumors.

#79 PTOV-1 overexpression in neuroendocrine tumors: a new molecular marker
Introduction: PTOV-1 (Prostate Tumor Overexpressed-1) is a novel protein encoded by 12-exon gene localized in chromosome 19q.13.3. Recently identified as an androgen-induced gene, it is involved in prostate cell proliferation and in prostate human cancer. PTOV-1 expression has been demonstrated in neuroendocrine cells of normal prostate tissue. Preliminary data indicate that PTOV-1 can be related to flotilin, integrins and other cellular factors involved in cancer progression.

#1115 Cancer Stem Cells in Small Intestine Neuroendocrine Cell Line P-STS: Isolation and Molecular Characterisation
Introduction: Cancer stem cells (CSCs) represent a small subpopulation of tumour cells responsible for invasive tumour growth. Even though the presence of CSCs in neuroendocrine tumours is documented, their role in neuroendocrine tumourigenesis and metastasis is not defined as yet.
