Outline of Final Research Achievements

Genome-wide copy number analysis in human gastric carcinoma identifed an amplified gene locus including vascular endothelial growth factor A (VEGFA). VEGFA gene amplification was validated by fluorescence in situ hybridization assay. The levels of VEGFA gene amplifications were positively associated with the levels of VEGFA protein expressions. VEGFA gene amplification with VEGFA overexpression suggested to be associated with decreased M2 macrophages at the tumor front in gastric cancer.

Academic Significance and Societal Importance of the Research Achievements

胃癌においては、現在、HER2に対する分子標的治療薬であるTrastuzumabおよびVEGFR2に対する治療薬であるRamucirumabが使用されている。
今後は臓器横断的な薬剤開発により、分子標的治療薬の急増が予想される。そしてこれらの治療薬の対象となる患者選定のための効果的なマーカーも必要とされることとなる。
本研究における胃癌検体に対する包括的な遺伝子コピー数の解析の結果から、VEGFA遺伝子を含む染色体領域の増幅が示唆された。VEGFAは分子標的治療であるBevacizumabの標的遺伝子であり、その遺伝子増幅は投薬の適応となる患者選定のためのマーカーとして使用できる可能性がある。
