Abstract
Trabectedin is a chemotherapy agent originating from a tunicate, Ecteinascidia turbinata. In this study, DNA-independent action mechanisms of trabectedin are investigated in prostate cancer (PCa) cells. Cell viability was assessed via XTT assay. Apoptosis was evaluated via flow cytometry. Tetramethylrodamine ethyl ester (TMRE) dye was utilized to determine mitochondrial membrane potential (MMP). Cell cycle distribution was investigated via flow cytometric analysis. Reactive oxygen species (ROS) were monitored using fluorescence CM-H2DCFDA dye. Changes in CHOP, p-eIF2α, GRP78 and p-PERK which are endoplasmic reticulum (ER) stress-involved proteins were investigated via western blot. Trabectedin induced cytotoxicity and cell cycle arrest at the G2/M phase. Trabectedin decreased MMP via ROS generation in PCa cells. ER stress-related proteins CHOP, p-eIF2α, GRP78 and p-PERK were also elevated by trabectedin treatment indicating the induction of ER stress-induced apoptosis. The results of this study show that trabectedin may be an effective chemotherapeutic for PCa.

Abstract
The high mortality associated with oncological diseases is mostly due to tumors in advanced stages, and their management is a major challenge in modern oncology. Angiogenesis is a defined hallmark of cancer and predisposes to metastatic invasion and dissemination and is therefore an important druggable target for cancer drug discovery. Recently, because of drug resistance and poor prognosis, new anticancer drugs from natural sources targeting tumor vessels have attracted more attention and have been used in several randomized and controlled clinical trials as therapeutic options. Here, we outline and discuss potential natural compounds as salvage treatment for advanced cancers from recent and ongoing clinical trials and real-world studies. We also discuss predictive biomarkers for patients' selection to optimize the use of these potential anticancer drugs.

Abstract
INTRODUCTION Trabectedin (ET-743) is a synthetic marine derived alkylating agent, extracted originally from a Caribbean Sea sponge. It is approved for the treatment of Soft Tissue sarcomas (STS) in Europe and recently by the FDA for liposarcomas and leiomyosarcomas. AREAS COVERED Trabectedin has multiple mechanisms of action, including one targeting the FUS-CHOP oncogene in Myxoid/Round cell Liposarcomas. Numerous Phase I, II and III clinical trials have been conducted with Trabectedin. It has been studied as monotherapy or in combination with other chemotherapeutic agents. The recommended dose based on clinical trials is 1.5 milligrams/m(2) continuous infusion over 24 hours once every 3 weeks for STS with evidence of disease control in multiple clinical trials at this dose. The most common Grade 3/4 toxicities include neutropenia and transient noncumulative elevations of ALT and AST. Steroid pretreatment has shown efficacy in reducing liver and bone marrow toxicity. In phase III testing comparing trabectedin to dacarbazine, trabectedin was associated with a significantly improved progression free survival rate in patients with advanced lipo- and leiomyosarcomas. EXPERT OPINION Trabectedin is an important new addition to the limited treatment options currently available for STS, especially for patients with liposarcoma that have progressed on standard chemotherapeutic regimens.

Abstract
INTRODUCTION Trabectedin is an anti-tumor compound registered in Europe and in several other countries, for the second-line treatment of soft tissue sarcoma (STS) and for ovarian cancer in combination with liposomal doxorubicin. Trabectedin inhibits cancer cell proliferation mainly affecting the transcription regulation. Trabectedin also acts as a modulator of tumor microenvironment by reducing the number of tumor associated macrophages (TAM). Because of its unique mechanism of action, trabectedin has the potential to act as antineoplastic agent also in several solid malignancies, including breast cancer (BC). AREAS COVERED This article reviews the preclinical and clinical data of trabectedin focusing on development in metastatic BC (mBC). Comments regarding the nature and the results of these trials are included. EXPERT OPINION Trabectedin is thought to have a crucial activity with defective DNA-repair machinery and also in modulating the tumor micro-environment and the immune-system of cancer patients. From the current available data, we recognize a potential activity of trabectedin in mBC and support the renewed efforts to better elucidate the value of trabectedin in this indication.

Anti-cancer effect and gene modulation of ET-743 in human biliary tract carcinoma preclinical models. BMC Cancer 2014; 14:918.

Abstract
Background Standard chemotherapy in unresectable biliary tract carcinoma (BTC) patients is based on gemcitabine combined with platinum derivatives. However, primary or acquired resistance is inevitable and no second-line chemotherapy is demonstrated to be effective. Thus, there is an urgent need to identify new alternative (chemo)therapy approaches. Methods We evaluated the mechanism of action of ET-743 in preclinical models of BTC. Six BTC cell lines (TFK-1, EGI-1, TGBC1, WITT, KMCH, HuH28), two primary cell cultures derived from BTC patients, the EGI-1 and a new established BTC patient-derived xenografts, were used as preclinical models to investigate the anti-tumor activity of ET-743 in vitro and in vivo. Gene expression profiling was also analyzed upon ET-743 treatment in in vivo models. Results We found that ET-743 inhibited cell growth of BTC cell lines and primary cultures (IC50 ranging from 0.37 to 3.08 nM) preferentially inducing apoptosis and activation of the complex DNA damage-repair proteins (p-ATM, p-p53 and p-Histone H2A.x) in vitro. In EGI-1 and patient-derived xenografts, ET-743 induced tumor growth delay and reduction of vasculogenesis. In vivo ET-743 induced a deregulation of genes involved in cell adhesion, stress-related response, and in pathways involved in cholangiocarcinogenesis, such as the IL-6, Sonic Hedgehog and Wnt signaling pathways. Conclusions These results suggest that ET-743 could represent an alternative chemotherapy for BTC treatment and encourage the development of clinical trials in BTC patients resistant to standard chemotherapy.

Abstract
Among the pharmaceutical options available for treatment of ovarian cancer, attention has been increasingly focused on trabectedin (ET-743), a drug which displays a unique mechanism of action and has been shown to be active in several human malignancies. Currently, single agent trabectedin is approved for treatment of patients with advanced soft tissue sarcoma after failure of anthracyclines and ifosfamide, and in association with pegylated liposomal doxorubicin for treatment of patients with relapsed partially platinum-sensitive ovarian cancer. This review aims at summarizing the available evidence about the clinical role of trabectedin in the management of patients with epithelial ovarian cancer. Novel perspectives coming from a better understanding of trabectedin mechanisms of action and definition of patients subgroups likely susceptible to benefit of trabectedin treatment are also presented.

Abstract
Trabectedin (Yondelis, ET-743), a semi synthetic tetrahydroisoquinoline alkaloid that was originally derived from the marine tunicate Ecteinascidia turbinata. The objective of this study was to investigate whether trabectedin mediated apoptosis shows any diversity in human breast cancer cell lines with different genotypes. Trabectedin induced cytotoxicity and apoptosis in both breast cancer cells in a time and concentration-dependent manner. The expression levels of the death receptor pathway molecules, TRAIL-R1/DR4, TRAIL-R2/DR5, FAS/TNFRSF6, TNF RI/TNFRSF1A, and FADD were significantly increased by 2.6-, 3.1-, 1.7-, 11.2- and 4.0-fold by trabectedin treatment in MCF-7 cells. However, in MDA-MB-453 cells, the mitochondrial pathway related pro-apoptotic proteins Bax, Bad, Cytochrome c, Smac/DIABLO, and Cleaved Caspase-3 expressions were induced by 4.2-, 3.6-, 4.8-, 4.5-, and 4.4-fold, and the expression levels of anti-apoptotic proteins Bcl-2 and Bcl-XL were reduced by 4.8- and 5.2-fold in MDA-MB-453 cells. Moreover, trabectedin treatment increased the generation of ROS in both breast cancer cells. We have shown that trabectedin causes selective activation of extrinsic and intrinsic apoptotic pathways in two genotypically different breast cancer cells. This preliminary data might guide clinicians to choose appropriate combination agents with trabectedin based on different molecular subtypes of breast cancer.
