Dr. Hsu’s research interest is to investigating the oncogenic mechanisms that induce DNA damage, chromosomal instability, mitotic catastrophe, neoplastic multinucleation, tumor progression, metastasis and microenvironment. Dr. Hsu’s current works focus on the fundamental mechanism of MCT-1 oncogene in promoting of tumor metastasis and malignant microenvironment. Her laboratory has identified the oncogenic kinase pathways involving the microRNA biogenesis, EMT signaling activation and tumor progression/metastasis. Dr. Hsu has confirmed the clinical relevance of the MCT-1 activation in different types of aggressive breast cancers and lung carcinoma. Her laboratory also establishes a unique ex vivo three dimensional dissection of tumorigenic microenvironment to analyze the therapeutic effect and utilizes an in vivo animal work to demonstrate the tumorigenic outcomes upon gain or loss of the oncogenic activity. These findings have good prospects to develop new diagnosis and effective therapeutic methods that administrate aggressive chemo/radio-resistant carcinomas.

MCT-1 is an RNA-binding protein involving in the translational initiation. Dr. Hsu lab have proved that MCT-1 oncogene is highly expressed in lung adenocarcinoma and in triple negative breast cancer. Aberrant activation of MCT-1 in cancer cells induces generation of intracellular ROS, tumor-promoted cytokines and the miRNAs which potentially activate the differentiation of immune cells, endothelial cells and fibroblasts. Moreover, MCT-1 overexpression induces EMT signaling cascade via activation of EGFR and Src pathway by which promote tumor progression and metastasis. Therefore, suppressing the MCT-1 oncogenic mechanism may strengthen the cancer therapeutic outcomes. Furthermore, combining the effect of tumor suppressor miRNAs induced by loss-function of MCT-1 and the therapeutic agent(s) may be innovative way for change of tumor microenvironments and for achievement of maximal therapeutic outcome.

Centrosome amplification and chromosome abnormality are frequently identified in neoplasia and tumorigenesis. Dr. Hsu has demonstrated that MCT-1 is a novel centrosomal protein that may be independent of its translation function. Targeting MCT-1 results in intercellular bridging, chromosome mis-segregation, cytokinesis delay and post-mitotic death. Furthermore, loss-function p53 alongside MCT-1 overexpression promote pleiotropic mitotic catastrophes, including centrosome amplification, chromosome missegregation, and cytokinesis failure. Consequently, the incidences of nuclear aberration and chromosomal instability are dramatically increased. Thereby, the studies identify the information for understanding the stepwise progression of tumors under the oncogenic stress.

Src homolog and collagen homolog (Shc) compromised three isoforms with distinct molecular weights (46, 52 and 66 kDa) is the adaptor proteins that transmit the signaling of cell surface receptors, such as EGF receptor (EGFR), erbB-2 receptor and insulin receptor. Overexpressing Shc proteins play important roles in mitogenesis, carcinogenesis and metastasis. Dr. Hsu has proved that MCT-1 is a novel regulator of Shc-Ras-MEK-ERK signaling and demonstrated for the first time that both MCT-1 and Shc genes are highly activated in human lung and breast cancers. Knockdown of MCT-1 enhances apoptotic cell death accompanied with reduction of Shc, activation of caspases and cleavage of the substrates under environmental stress. Moreover, the cancer cell proliferation, chemo-resistance and tumorigenic capacity are effectively suppressed by silencing MCT-1. Collectively, enhanced MCT-1 activation can be recognized as a biomarker for tumor development and served as a therapeutic target.

Multinucleation is associated with malignant neoplasms. Dr. Hsu demonstrates that increased MCT-1 expression antagonizes the functional activity of PTEN that promotes PI-3K/AKT signaling, survival rate and the malignant effects particular in PTEN-deficient condition. MCT-1 physically interacts with p190B and Src in vivo, supporting they are in proximity of the signaling complexes. The Src/p190B signaling function that leads to inhibition of RhoA activity is synergistically augmented by MCT-1 overexpression and PTEN loss. Through Src/p190B/RhoA pathway, MCT-1 enhances the incidences of mitotic catastrophe in spindle multipolarity and cytokinesis failure that drive neoplastic multinucleation. Most important, targeting MCT-1 dramatically represses the Src/p190B signaling cascade that improves nuclear structure and suppresses tumorigenicity of PTEN-null breast cancer cells. Clinical evidence also further confirms that MCT-1 gene stimulation is correlated with p190B gene promotion and PTEN gene suppression in human breast cancer. Accordingly, MCT-1 gene induction can be recognized as a potential biomarker of breast tumor development. Abrogating MCT-1 function may be a promising stratagem for management of breast cancer involving Src hyperactivation and/or PTEN dysfunction.

 Hus - figAberrant nuclear organizationUnsynchronized cell cycle progression occurs in the multi-nuclear cell (denoted by arrow, asterisk, and star).

Multinucleation is often identified in cancer cells. Dr. Hsu’s lab found that multinucleate cells were greatly increased when oncogene MCT-1 is overexpressed and p53 is suppressed. Her lab found three interphase nuclei (arrow), a mitotic nucleus with chromosome alignment at the metaphase plate (star) and some micro-nuclei (asterisk) that were all enclosed within a single cell. This proves that unsynchronized cell cycle progression at different nuclear compartments of a multi-nuclear cell enable perpetuate the rate of aneuploidy and promote chromosomal instability during tumor progression.

Dr. Hsu’s lab further found that MCT-1 physically interacts with p190B and Src in vivo and induces the Src/p190B signaling function that inhibits RhoA activity in PTEN loss condition. Through MCT-1/Src/p190B/RhoA pathway, the incidences of mitotic catastrophe in spindle multipolarity and cytokinesis failure that drive neoplastic multinucleation are dramatically enhanced. Most important, targeting MCT-1 dramatically represses the Src/p190B signaling that improves nuclear structure and suppresses tumorigenicity of PTEN-null breast cancer cells. MCT-1 gene induction has now been recognized as a potential biomarker of breast cancer development. Abrogating MCT-1 activity may be promising stratagem for management of breast cancer. This study not only uncovers a novel mechanism of nuclear aberration but also offers new strategy for cancer treatment. (Oncogene. 2014. 33:5109-5120).
