Main theme

Cells maintain their function and morphology by exploiting a suitable adaptive response system to diverse and complex tissue microenvironments. Several lines of evidence have suggested that hypoxic, acidic and nutrients-depleted microenvironments exist in solid tumors and induce malignant phenotypes and chemo/radioresistance of cancer cells (Figure 1). We aim at elucidating molecular mechanisms responsible for cellular adaptive responses to the tumor-specific microenvironments and malignant progression of cancer cells (Figure 2).

  • Cellular adaptive responses to tumor microenvironments, e.g. hypoxia
  • Molecular mechanisms underlying malignant progression and chemo/radioresistance of cancer cells
  • Regulatory mechanisms of carbohydrate metabolic pathway
