Abstract
Metastases represent the end products of a multistep cell-biological process termed the invasion-metastasis cascade, which involves dissemination of cancer cells to anatomically distant organ sites and their subsequent adaptation to foreign tissue microenvironments. Each of these events is driven by the acquisition of genetic and/or epigenetic alterations within tumor cells and the co-option of nonneoplastic stromal cells, which together endow incipient metastatic cells with traits needed to generate macroscopic metastases. Recent advances provide provocative insights into these cell-biological and molecular changes, which have implications regarding the steps of the invasion-metastasis cascade that appear amenable to therapeutic targeting.

This is one of two papers showing that glioblastoma cells can differentiate into functional endothelial cells as part of the tumour vasculature. These endothelial cells are characterized by the same genetic alterations as the glioblastoma cells. The tumour-derived endothelial cells originate in putative glioblastoma-initiating cells and are functionally important for tumorigenesis.

Macrophages are abundant in tumours, where they promote tumorigenesis and metastasis. Jeffrey Pollard and colleagues now identify inflammatory monocytes as a precursor population for the macrophages that promote breast cancer metastasis to the lung or bone. These cells are recruited through the cytokine CCL2 and promote tumour-cell extravasation (by producing the signal protein VEGF) and the seeding of metastases. These findings can explain the poor prognosis for breast cancer patients with elev...

Summary Mechanotransduction is a key determinant of tissue homeostasis and tumor progression. It is driven by intercellular adhesions, cell contractility, and forces generated within the microenvironment and is dependent on extracellular matrix composition, organization, and compliance. We show that caveolin-1 (Cav1) favors cell elongation in three-dimensional cultures and promotes Rho- and force-dependent contraction, matrix alignment, and microenvironment stiffening through regulation of p190R...

Dissemination of ovarian tumors involves the implantation of cancer spheroids into the mesothelial monolayer on the walls of peritoneal and pleural cavity organs. Biopsies of tumors attached to peritoneal organs show that mesothelial cells are not present under tumor masses. We have developed a live, image-based in vitro model in which interactions between tumor spheroids and mesothelial cells can be monitored in real time to provide spatial and temporal understanding of mesothelial clearance. H...

Tenascin C is an extracellular matrix protein previously linked to breast cancer metastasis. Here the authors uncover how tenascin C promotes the fitness of metastasis-initiating cells by sustaining the stem and survival signaling pathways NOTCH and Wnt through specific regulation of Msi1 and Lgr5, respectively.

When cancer metastasizes to bone, considerable pain and deregulated bone remodelling occurs, greatly diminishing the possibility of cure. Metastasizing tumour cells mobilize and sculpt the bone microenvironment to enhance tumour growth and to promote bone invasion. Understanding the crucial components of the bone microenvironment that influence tumour localization, along with the tumour-derived factors that modulate cellular and protein matrix components of bone to favour tumour expansion and in...

Vessel normalization strategies aim to increase tumour perfusion and oxygenation, and have the potential to reduce metastasis and improve responses to conventional anticancer therapies. Here, Carmeliet and Jain discuss the benefits and limitations of this emerging new treatment paradigm for cancer and other angiogenic disorders.

1described the presence of cell-free nucleic acid (cfNA) in human blood for the first time. This attracted little attention in the scientific community and it was not until 1994 that the importance of cfNA was recognized as a result of the detection of mutated RAS gene fragments in the blood of cancer patients 2,3 (TIMELINE). In 1996, microsatellite alterations on cell-free DNA (cfDNA) were shown in cancer patients 4

In a mouse model of lung cancer driven by activated K-Ras and p53 loss, Jacks and colleagues describe a method for tracing individual metastases back to the primary tumours, allowing non-metastatic lesions to be distinguished from metastatic lesions in the same animal. A comparison of gene-expression signatures between metastatic and non-metastatic tumours with human lung cancers led to the identification of Nkx2-1/TTF-1 as a gene that is down-regulated during tumour progression in mice, and ass...

Summary Tumor-infiltrating myeloid cells convey proangiogenic programs that counteract the efficacy of antiangiogenic therapy. Here, we show that blocking angiopoietin-2 (ANG2), a TIE2 ligand and angiogenic factor expressed by activated endothelial cells (ECs), regresses the tumor vasculature and inhibits progression of late-stage, metastatic MMTV-PyMT mammary carcinomas and RIP1-Tag2 pancreatic insulinomas. ANG2 blockade did not inhibit recruitment of MRC1 + TIE2-expressing macrophages (TEMs) b...

Abstract Multifunctional nanoplatforms for the early diagnosis and precise treatment of cancers have been widely explored in nanomedicine but still suffer from complex material design and intrinsic incompatibility among various biomaterial components. Moreover, a rational mode of tumor therapy that considers the effect of immune adjuvants while promoting long-term cancer immunotherapy is highly needed. Herein, we developed smart metal-free two-dimensional (2D) graphitic carbon nitride/chlorin e6...

Abstract null null Fascin is a pro-metastatic actin-bundling protein that is upregulated in all metastatic carcinomas. Fascin promotes cancer cell migration and invasion by facilitating membrane protrusions, such as filopodia and invadopodia. Aerobic glycolysis is a key feature of cancer metabolism and provides critical intermediate metabolites for tumor growth. Here, we report that fascin increases glycolysis in lung cancer to promote tumor growth and metastasis. Fascin promotes glycolytic flux...

Hypoxia-inducible factor-1 (HIF-1) plays essential roles in human diseases, though its central role in oxygen homoeostasis hinders the development of direct HIF-1-targeted pharmacological approaches. Here, we surveyed small-molecule compounds that efficiently inhibit the transcriptional activity of HIF-1 without affecting body homoeostasis. We focused on Mint3, which activates HIF-1 transcriptional activity in limited types of cells, such as cancer cells and macrophages, by suppressing the facto...

Tumor acidic microenvironment is the main feature of many solid tumors. As a part of the tumor microenvironment, it has a profound impact on the occurrence and development of tumors. However, the research on how tumor cells sense the changes of the external microenvironment and how the intracellular subcellular structures transmit the signals from extracellular to intracellular is unclear. In this study, we identify that the acidic microenvironment enhances cancer cell motility, and the expressi...

Previously, we showed that mice treated with cyclophosphamide (CTX) 4 days before intravenous injection of breast cancer cells had more cancer cells in the lung at 3 h after cancer injection than control counterparts without CTX. At 4 days after its injection, CTX is already excreted from the mice, allowing this pre-treatment design to reveal how CTX may modify the lung environment to indirectly affect cancer cells. In this study, we tested the hypothesis that the increase in cancer cell abundan...

Gastric cancer (GC) is considered one of the most common gastrointestinal malignancies worldwide. Circular RNAs (circRNAs) are a new class of endogenous noncoding RNAs, which can be used as biomarkers and therapeutic targets for many tumors. However, the role and potential regulatory mechanisms of circRNAs in GC remain unclear. In this study, we demonstrated that a specific circRNA, circHAS2, was upregulated in GC tissues and cells and was positively correlated with tumor metastasis. In vitro ex...
