Abstract
Somatostatin analogues (SAs) are potential anticancer agents. This study was designed to investigate the expression of somatostatin receptors (SSTRs) in melanoma cells and the effect of two SAs on cell proliferation and viability. Eighteen primary and metastatic human cutaneous melanoma cell lines were treated with octreotide and SOM230. Expression of SSTR1, SSTR2, SSTR3 and SSTR5 was assessed by real-time polymerase chain reaction. Proliferation, viability and cell death were assessed using standard assays. Inhibition was modelled by mixed-effect regression. Melanoma cells expressed one or more SSTR. Both SAs inhibited proliferation of most melanoma cell lines, but inhibition was < 50%. Neither SA affected cell viability or induced cell death. The results suggest that melanoma cell lines express SSTRs. The SAs investigated, under the conditions used in this study, did not, however, significantly inhibit melanoma growth or induce cell death. Novel SAs, combination therapy with SAs and their anti-angiogenic properties should be further investigated.

Abstract
e16555 Background: Endometrial carcinoma (EC) frequently shows deregulation of the extrinsic apoptotic pathway. One of the critical regulators of apoptosis resistance in EC is FLIP, under the control of NFkB and a cellular complex composed of CK2, KSR1, and BRAF. Methods: Four different EC cell lines, which are known to exhibit resistance to TRAIL/FAS-induced apoptosis (Ishikawa, KLE, HEC1A, and RL-95) were exposed to various pharmacologic substances that target proteins involved in the regulation of the extrinsic apoptotic pathway and receptor tyrosine kinases including bortezomib, sorafenib, sunitinib, DRB, apigenin, MG-132, epoxomicin, and ALLN. Moreover, EC cell lines were subjected to down-regulation of several of these genes (FLIP, CK2, KSR1, and BRAF) by shRNA. Cell viability and apoptotic morphology was determined. Results were validated in tumor cell explants. Results: Bortezomib induced cell death on EC cells and primary explants to a 70% extent. However, 100% of treated explants and cell lines activated NF-kB instead of blocking its transcriptional potential. Combination of sunitinib plus bortezomib induced 75% fold reduction in NFkB activity and induced a 5% of synergistic increse of apoptotic cell death in Ishikawa cells. Treatment of the four cell lines with TRAIL failed to induce cell death. However, FLIP knock-down sensitized the cells to TRAIL-induced apoptosis (80%). Moreover, down-regulation of CK2, KSR1, and BRAF by pharmacological inhibition, or shRNA, reduced FLIP cellular levels, and induced TRAIL-dependent apoptosis in 70%-100% of EC cell lines tested. Sorafenib induced a dose-dependent cell death in all four cell lines, to a 70%-100% extent at 48 hours. Conclusions: In vitro pharmacologic targeting of the apoptotic pathway effectively induces cell death in EC cell lines. These findings justify clinical trials with these agents in EC.

Abstract
BACKGROUND Cutaneous malignant melanoma is an aggressive type of skin cancer which causes disproportionate mortality in young and middle-aged adults. Once disseminated, melanoma can be considered an incurable disease, highly resistant to standard antineoplastic treatment, such as chemotherapy or radiation therapy. The proteasome represents a novel target for cancer therapy that can potentially be used in melanoma. OBJECTIVES To assess the effect of four structurally different proteasome inhibitors on human cutaneous melanoma-derived cell lines. METHODS Sixteen human cutaneous melanoma-derived cell lines which are original were obtained from patients who were treated by two of the authors. Cells were cultured, exposed to proteasome inhibitors (bortezomib, ALLN, MG-132 and epoxomicin) and then assayed for cell cycle and cell death analyses. RESULTS Proteasome inhibitors inhibited the in vitro growth of melanoma cells, and this effect was due to a reduction in cell proliferation rate and an induction of both caspase-dependent and caspase-independent cell death. Moreover, release of apoptosis-inducing factor was observed in the presence of the broad-specificity caspase inhibitor BAF (Boc-D-fmk). In addition, the four different proteasome inhibitors induced caspase 2 processing. CONCLUSIONS This study provides information regarding the in vitro effects of proteasome inhibitors on melanoma cell lines, and the molecular mechanisms involved. It also gives support to the future use of such inhibitors in the treatment of patients with melanoma, either administered alone or in combination with other drugs.
