猪的 HCC 模型
肝细胞癌(HCC)是最常见的原发性肝癌类型,占病例的75-85%。一些动物模型,包括转基因小鼠模型,可用于研究HCC发病机制和测试新的治疗方法。然而,这些模型有很大的局限性,包括与人类相比在尺寸、代谢率和药物代谢方面的差异。为了规避这些限制并改善临床翻译,研究人员开发了一种具有定制肿瘤突变的肝细胞癌猪模型。该模型基于Oncopig,这是一种先前描述的转基因猪模型,具有Cre重组酶诱导的KRAS和TP53突变表达。Elkhadragy等人从Oncopigs中分离出肝细胞,在通过CRISPR基因编辑引入额外的突变(PTEN和CDKN2A)之前,将这些细胞暴露于Cre重组酶,将其转化为HCC细胞。接下来,研究小组使用经皮肝注射或门静脉注射将crispr编辑的HCC细胞植入Oncopigs,导致肿瘤的发展。该方法是在具有特定突变的大型癌症动物模型中评估新的治疗策略的有前途的工具。原始文献:Elkhadragy, L.等。型号机械18,dmm052079 (2025)

期刊介绍: LabAnimal is a Nature Research journal dedicated to in vivo science and technology that improves our basic understanding and use of model organisms of human health and disease. In addition to basic research, methods and technologies, LabAnimal also covers important news, business and regulatory matters that impact the development and application of model organisms for preclinical research. LabAnimal's focus is on innovative in vivo methods, research and technology covering a wide range of model organisms. Our broad scope ensures that the work we publish reaches the widest possible audience. LabAnimal provides a rigorous and fair peer review of manuscripts, high standards for copyediting and production, and efficient publication.
