Outline of Final Research Achievements |
In 3 types (HLE, HLF, HepG2) of HCC cultured cell lines,telmisartan showed cell growth inhibitory effect, and 2 types (HuH-7, PLC / PRF / 5)were not delected anti-tumor effect.G1 arrest was observed due to the reduction in the expression of cyclinD1, Cdk4 and cyclinE induced from G1 to S phase of the cell cycle by the addition of telmisartan. Increased expression of phospho-p53 (Ser392) and decreased expression of survivin, increased degradation product of CCK-18 were detected, and induction of apoptosis were also observed.

Academic Significance and Societal Importance of the Research Achievements |
降圧薬telmisartanはいくつかのHCC細胞株でmiRNAを介したG1アレストおよびアポトーシスの誘導を起こし、抗腫瘍効果を併せ持つ薬剤と考えられる。本研究は、今後高血圧や糖尿病性腎症を有するHCC患者にどの降圧薬を選択するかの1つの指針となる。
