(A)- 指摘項目No.27
論文#10のFigure 3 (C)の再下段のMCP-1の画像全6列分は、
論文#13のFigure 4 (A)のiNOSの画像全6列分(Fruct, Fruct/BH4の画像)や、
論文#16のFigure 5 (b)のiNOS Proteinの画像右6列分(BH4 only, AngII, AngII/BH4の画像)と、
類似しており、画像の流用(データ捏造)が疑われます。

(A)- 指摘項目No.28
論文#13のFigure 4 (A) のeNOSの画像全6列分は、
論文#16のFigure 5 (a)のeNOS Proteinの画像右6列分(BH4 only, AngII, AngII/BH4の画像)と、類似している。
さらに、この二つの画像は、
論文#14のFigure 4(B)のMCP-1の画像の左から3,4,5,6,7,8列目の6列分の画像を左右逆にした画像にも、
類似しており、画像の流用(データ捏造)が疑われます。

Fig. 3. SKase activation is involved in globular adiponectin-induced activation
of NF-κB and adhesion molecule expression. (A) Treatment of cells with SKase
siRNA inhibited globular adiponectin-induced NF-κB activation. Data are
means±SD of at least three independent repetitions. ⁎Pb0.01 compared with
the value of gAd. (B) Treatment of cells with SKase siRNA markedly decreased
adiponectin-induced mRNA levels of adhesion protein expression. White bars:
control, grey bars: control treated with SKase siRNA, black bars: gAd, hatched
bars: gAd treated with SKase siRNA. Data are means±SD of at least three
independent repetitions and are shown as ratios against GAPDH. ⁎Pb0.01
compared with the value of gAd. (C) Treatment of cells with siRNA suppressed
globular adiponectin-induced protein levels of VCAM-1, ICAM-1, E-selectin,
and MCP-1. Experiments were performed in duplicate.
