Atabey Lab. on Cancer Biology and Signaling

Overview

Atabey Lab. has been working in the field of Cancer Biology and Signaling. The scientific goal of our group is to fill the gaps in the fundamental biological mechanisms underlying the development and progression of cancer. Over the past two decades, our group has been working on to develop deeper understanding the role of signal transduction cascade in cancer development and progression and using this molecular knowledge to improve the diagnosis and treatment of cancer.

Specific Goals

1) Identification of the potential reciprocal crosstalk between c-Met receptor and other signaling molecules and their cooperative interaction in drug resistance in HCC
2) Investigating HGF/c-Met axis in tumor microenvironment and metastasis formation in the liver
3) Identification of the potential reciprocal crosstalk between HGF/c-Met signaling and glucose metabolism in HCC using various in vitro and in vivo models and further use this knowledge for developing strategies to prevent HCC
4) Identification of the roles of non-coding RNAs in the regulation of c-Met signaling in HCC
5) Deciphering signaling pathways in clinical samples for precision medicine using omics technologies
6) The use of omics data obtaining by our group and by the literature to investigate signaling mechanisms in metastasis and cancer by using in silico methods
7) Fabrication and validation of Lab-on-a-chip (LOC) system to predict metastatic and invasive ability to circulating tumor cells
8) Application of LOC in the early stage of anti-metastatic drug discovery focusing on gene expressions, receptor signaling and susceptibility
