一直造假一直爽!顶尖学者尹善善的12篇高水平文章被撤回
研发家 | 2024-10-17 0

肿瘤诱导的新血管生长主要来自宿主器官微血管内皮细胞(EC),而肺和肝的微血管存在显著差异。血管内皮生长因子(VEGF或VEGF-A)促进肿瘤血管生成被认为主要由VEGF受体-2 (VEGFR-2)介导。

2010年10月24日,哈佛医学院Sam S Yoon(音译,尹善善)团队在Cancer Research 在线发表题为“Differential effects of VEGFR-1 and VEGFR-2 inhibition on tumor metastases based on host organ environment”的研究论文,该研究表明,肝转移比肺转移更依赖于VEGFR-1来介导血管生成,这是由于肝EC与肺EC中VEGFR-1的活性不同。因此,抑制特异性VEGFRs的治疗应考虑转移性疾病的靶向部位。

但是,在2024年10月15日,该文章被撤回,主要原因是图片重复使用。

截至到2024年10月17日,由Sam S Yoon作为负责人的已经被撤回包括在Cancer ResearchCLINICAL CANCER RESEARCH Cell Death & Disease 发表的12篇高水平文章(2024年10月15日被撤回5篇文章),后续会有更多的文章被撤回,iNature持续关注。

应编辑们的要求,这篇文章已被撤回。编辑的内部审查发现,在图2a中使用了相同的图像来表示1 - 6车道和7-12车道的Total VEGFR-2,并且在补充图S2B和S4A中使用了相同的图像来表示1车道的VEGFR-1。
此外,在Fig 2a的Phospho-VEGFR-1 Western blot图像中,肺EC和肝EC样本之间以及Fig S4A补充图中β-actin图像中,正常肺和肺转移样本之间似乎存在剪接。当使用图像分析软件对图形应用自适应直方图均衡化时,注意到这些拼接改变。
这份撤稿通知的副本已发送到所有七名作者最后已知的电子邮件地址。一位作者(Daniel L. Karl)同意撤稿;一位作者(Sam S. Yoon)不同意撤稿;5位作者(Yoon-Jin Lee、Ugwuji N. Maduekwe、Courtney Rothrock、Sandra Ryeom和Patricia A. D’amore)没有回应。
