Overview

Cancer has been the leading cause of death in Japan. Metastasis, the spread of cancer to other parts of the body, accounts for about 90% of cancer deaths. Therefore, the control of metastasis is one of the most important issues in the treatment of cancer. However, as the molecular mechanisms regulating metastasis remain incompletely understood, further biological analyses are necessary for deeper understanding to develop anti-metastasis therapy. We aim to understand the role of cellular structures called invadopodia that play important roles in cancer metastasis. We also intend to reveal the mechanisms underlying peritoneal metastasis of scirrhous gastric carcinoma, an aggressive and refractory subtype of gastric carcinoma whose incidence is high in Japan. Our research should provide important insights into the molecular basis of cancer metastasis and lead to the development of novel cancer therapeutics targeting metastasis.

Projects

1. Molecular mechanisms of invadopodia formation and their roles in blood-borne metastasis

Invadopodia are membrane protrusions formed by invasive cancer cells. Invadopodia are rich in actin filaments and matrix metalloproteases with the ability to degrade extracellular matrix (Figs. 1A and B). So far, we have identified several structural and regulatory components of invadopodia and elucidated their functions in invadopodia formation. Moreover, our approach demonstrated that invadopodia play a pivotal role in invasion and hematogenous metastasis of breast cancer (Fig. 1C). We have recently identified several novel components of invadopodia and undertaken their detailed characterization to clarify the molecular mechanisms of invadopodia formation. We are also seeking novel functional molecules and inhibitory compounds by high-throughput screening of gene and chemical libraries, respectively, using invadopodia formation as a readout.

Actin-rich invadopodia were formed at the ventral surface of the cell and the degradation sites of fluorescent gelatin were observed (arrowheads). C) The role of invadopodia in cancer invasion and metastasis. In hematogenous metastasis, invadopodia degrade extracellular matrix within the basement membrane and the blood vessel wall, thereby promoting cancer cell invasion and extravasation.

2. Molecular mechanisms of peritoneal dissemination of scirrhous gastric carcinoma

Scirrhous gastric carcinoma is a refractory carcinoma with poor prognosis owing to its difficulty in early detection, rapid infiltrative growth, and frequent peritoneal dissemination. We are investigating molecular mechanisms governing the aggressive phenotypes of scirrhous gastric carcinoma. We identified several signaling pathways and molecules specifically activated in scirrhous gastric carcinoma. Their roles in peritoneal dissemination and potentials as therapeutic targets are under investigation. Since scirrhous gastric carcinoma is associated with massive fibrosis, we also assess the involvement of tumor microenvironment, including interaction between carcinoma cells and stromal fibroblasts (Fig. 2). Moreover, we make an attempt to visualize tumor clonality and heterogeneity of peritoneally disseminated tumors by multi-color fluorescent imaging (Fig. 3). Our work will contribute to elucidation of the molecular mechanisms underlying progression of scirrhous gastric carcinoma and lead to the development of innovative cancer therapeutics.
