Abstract
Colorectal cancer (CRC) is one of the most common cancers and a leading cause of mortality worldwide. Small extracellular vesicles (sEVs) are nano-sized extracellular vesicles containing a variety of bioactive molecules, such as nucleic acids, proteins, lipids, and metabolites. Recent evidence from CRC has revealed that sEVs contribute to tumorigenesis, progression, and drug resistance, and serve as a tool for "liquid biopsy" and a drug delivery system for therapy. In this review, we summarize information about the roles of sEVs in the proliferation, invasion, migration, epithelial-mesenchymal transition, formation of the premetastatic niche, and drug resistance to elucidate the mechanisms governing sEVs in CRC and to identify novel targets for therapy and prognostic and diagnostic biomarkers.

Abstract
Nanosized drug delivery systems have emerged to improve the therapeutic performance of anticancer drugs. Here, an amphiphile-based nanoparticle consisting of amphiphilic prodrug N-[3b-acetoxy-urs-12-en-28-oyl]-amino-2-methylpiperazine was developed (UP12 NPs) with uniform sizes (~100 nm), which possessed the advantages of small molecules and nanomedicine. The positively charged UP12 NPs significantly enhanced the cellular drug uptake on HepG2 cells than negatively charged UA NPs. Meanwhile, UP12 and these therapeutic amphiphile-based nanoparticles could induce cell apoptosis more efficiently than that of UA and UA NPs. Moreover, molecular docking demonstrated that the UP12 and intercellular adhesion molecule 1 (ICAM-1) could dock well. UP12 and UP12 NPs significantly decreased the mRNA expression of ICAM-1 and inhibited the migration and adhesion of liver cancer cells (HepG2 cells), which indicated that UP12 might be one of the potential ICAM-1 inhibitors. In vivo, UP12 NPs enhanced tumor accumulation, inhibited tumor lung metastasis and showed good biocompatibility. Overall, UP12 or UP12 NPs could be developed as prospective drugs for cancer metastasis therapy via ICAM-1 mediated cell adhesion. STATEMENT OF SIGNIFICANCE: In this study, we fabricated the therapeutic amphiphile-based nanoparticles by assembly of ursolic acid piperazine derivative N-[3b-acetoxy-urs-12-en-28-oyl]-amino-2-methylpiperazine (name as UP12 NPs) with low cytotoxicity. UP12 NPs exhibited spherical morphology and uniform sizes. Particularly, these therapeutic amphiphile-based nanoparticles significantly enhanced tumor accumulation and inhibited tumor lung metastases via intercellular adhesion molecule 1 (ICAM-1) mediated cell adhesion.

Abstract
The primary cause of cancer-related death from solid tumors is metastasis. While unraveling the mechanisms of this complicated process continues, our ability to effectively target and treat it to decrease patient morbidity and mortality remains disappointing. Early detection of metastatic lesions and approaches to treat metastases (both pharmacological and genetic) are of prime importance to obstruct this process clinically. Metastasis is complex involving both genetic and epigenetic changes in the constantly evolving tumor cell. Moreover, many discrete steps have been identified in metastatic spread, including invasion, intravasation, angiogenesis, attachment at a distant site (secondary seeding), extravasation and micrometastasis and tumor dormancy development. Here, we provide an overview of the metastatic process and highlight a unique pro-metastatic gene, melanoma differentiation associated gene-9/Syntenin (MDA-9/Syntenin) also called syndecan binding protein (SDCBP), which is a major contributor to the majority of independent metastatic events. MDA-9 expression is elevated in a wide range of carcinomas and other cancers, including melanoma, glioblastoma multiforme and neuroblastoma, suggesting that it may provide an appropriate target to intervene in metastasis. Pre-clinical studies confirm that inhibiting MDA-9 either genetically or pharmacologically profoundly suppresses metastasis. An additional benefit to blocking MDA-9 in metastatic cells is sensitization of these cells to a second therapeutic agent, which converts anti-invasion effects to tumor cytocidal effects. Continued mechanistic and therapeutic insights hold promise to advance development of truly effective therapies for metastasis in the future.

Abstract
The contractile protein MYH9 (non-muscle myosin IIA) is an actin-binding protein that plays a fundamental role in cell adhesion, migration, and division. However, its distinct role in colorectal cancer (CRC) still remains unidentified. In this study, we detected significant MYH9 overexpression in CRC samples compared with paired normal tissues using western blotting and tissue microarray immunohistochemistry (IHC). Moreover, analysis of patient clinical information demonstrated that MYH9 overexpression was strongly correlated with lymph node metastasis and poor overall survival. Endogenous overexpression of MYH9 enhanced the ability of cell proliferation and migration in vitro, and accelerated CRC growth in mouse models. Silencing of MYH9 revealed repressive effects on CRC cells in vitro and in vivo. Furthermore, primary biomechanics that involved MAPK/AKT signaling mediated epithelial-mesenchymal transition (EMT) was uncovered underlying MYH9 dependent cell behaviors. Collectively, our data showed that MYH9 significantly promoted tumorigenesis by regulating MAPK/AKT signaling, and was remarkably correlated with poor prognosis in CRC. MYH9 may thus be a novel biomarker and drug target in the diagnosis and treatment of CRC.

Abstract
Phenylboronic acid (PBA)-mediated tumor targeting nanovector is an attractive strategy for enhancing siRNA delivery and treatment of metastatic cancers. However, its nonspecific binding with various biological membranes containing cis-diol moieties restricts its potential application by systematic administration. Herein, we constructed a novel pH-activated “sheddable” PEG-coated nanoparticle for effective treatment of primary tumors and metastases, which was based on the conjugation of catechol group modified poly(ethylene glycol) (PEG-Cat) and PBA-terminated polyethylenimine (PEI-PBA) via the borate ester formed between PBA and Cat. By virtue of the pH-dependent stability of borate ester in an aqueous medium, the PEG-shell could “shield” the PBA ligand in systemic circulation to reduce its “off-target effect”, while PEG was detached at tumor extracellular pH (~6.5) to expose intact PBA moiety. Simultaneously, the PBA ligand could bind with overexpressed sialic acid residues on cancer cells, giving rise to enhanced cellular internalization. In addition, the PBA moieties could also couple with each 3'-end ribose of double-stranded siRNA. siRNAs were used as both a payload and a pH-responsive intermolecular cross-linker, and thereby acquired sufficient stability during circulating in blood and a rapidly triggered release in response to acidic endosomal/lysosomal pH-stimuli. As a result, this dual pH-sensitive nanoparticle showed enhanced siRNA uptake, gene silencing efficacy and anti-metastatic effects in vitro. Furthermore, in vivo studies demonstrated that PBA-based nanoparticles effectively accumulated in tumor and inhibited tumor growth and metastasis in 4T1 orthotopic mammary tumor model after intravenous administration.

Abstract
The combination of chemotherapy and RNA interference is a promising approach for efficient cancer therapy. However, the success of such a strategy is hampered by the lack of suitable vectors to coordinate small interfering RNA (siRNA) and chemotherapeutic drug into one single platform. We herein report a novel triple-layered pH-responsive micelleplex loading siRNA and alkylated cisplatin prodrug for NF-Kappa B targeted treatment of metastatic breast cancer. The micelles were self-assembled from poly(ethylene glycol)-block-poly(aminolated glycidyl methacrylate)-block-poly(2-(diisopropyl amino) ethyl methacrylate) (PEG-b-PAGA-b-PDPA) triblock copolymers. At pH 7.4, the cisplatin prodrug was encapsulated in the hydrophobic PDPA core and siRNA was loaded on the positively charged PAGA interlayer to form the micelleplexes. The PEG corona can prevent protein absorption during blood circulation, minimize non-specific interaction with the reticuloendothelial system, and prolong the systemic circulation of the micelleplexes. The positively charged PAGA interlayer can facilitate deep tumor penetration of the micelleplexes, which, upon cellular uptake, are dissociated in the early endosomes to release anticancer drug payload due to protonation of the PDPA core. Using a 4T1 breast cancer model, we demonstrate that this novel micelleplex co-loaded with cisplatin prodrug and siRNA-p65 is able to simultaneously inhibit tumor growth and suppress distant metastasis of the cancer cells by downregulating NF-kappa B expression. The results reported in this study suggest that siRNA and anticancer drug co-delivery using pH-responsive micelleplexes is a promising strategy for efficient treatment of metastatic cancer.
