Epithelial Mesenchymal Transition in Drug Resistance and Metastasis of Lung Cancer
Fariz Nurwidya,Fumiyuki Takahashi,Akiko Murakami,Kazuhisa Takahashi 대한암학회 2012 Cancer Research and Treatment Vol.44 No.3
Among all types of cancer, incidence of lung cancer remains the highest with regard to cancerrelated mortality. Problems contributing to recurrence of the disease include metastasis and drug resistance. Mounting evidence has demonstrated involvement of epithelial mesenchymal transition (EMT) in cancer progression. EMT is a critical mechanism ensuring tissue remodeling during morphogenesis of multicellular organisms. Therefore, understanding of the biology of this process for identification of potential EMT-targeted therapeutic strategies for the benefit cancer patients is necessary. This review describes recent evidence of EMT involvement in drug resistance and metastasis of cancers, with an emphasis on lung cancer.

From tumor hypoxia to cancer progression
Fariz Nurwidya,Fumiyuki Takahashi,Kunihiko Minakata,Akiko Murakami,Kazuhisa Takahashi 대한해부학회 2012 Anatomy & Cell Biology Vol.45 No.2
Hypoxia, defined as a decrease of tissue oxygen levels, represents a fundamental pathophysiological condition in the microenvironment of solid tumors. Tumor hypoxia is known to be associated with radio/chemo-resistance and metastasis that eventually lead to cancer progression contributing to poor prognosis in cancer patients. Among transcription factors that accumulated under hypoxic conditions, hypoxia-inducible factor-1 (HIF-1) is a master transcription factor that has received the most intense attention in this field of research due to its capacity to modulate several hundred genes. With a clearer understanding of the HIF-1 pathway, efforts are directed at manipulation of this complex genetic process in order to ultimately decrease cellular HIF-1 levels. Some novel agents have been shown to have HIF-1 inhibition activity through a variety of molecular mechanisms and have provided promising results in the preclinical setting.
