中文摘要
在人类主要恶性肿瘤中,原发性肝癌占全球所有癌症和死亡人数的约9%,占全球癌症死亡人数的约12%。
发展中国家。肝癌占所有肝癌的85%,是世界上最主要的致命性恶性肿瘤之一。
在世界范围内。由病毒感染(乙肝病毒和丙型肝炎病毒)、酒精和非酒精或脂肪肝造成的慢性肝脏损害。
疾病-慢性脂肪肝(NAFLD)-与慢性支气管炎、肝纤维化、肝硬变或这些危险因素的组合有关。
增加了原发性肝癌的风险。尤其值得注意的是,NAFLD是代谢综合征的一种主要肝脏表现形式,影响了近25%的人。
在美国总人口中,由于肥胖症和代谢综合征的发病率越来越高,其发病率也在迅速上升。
流行病在世界范围内流行。尽管这些风险和因素都定义得很好,但肝癌仍然是一种侵袭性疾病和难以治疗的疾病。
恶性肿瘤的治疗效果很差,治疗方法的选择也很有限。事实上,要想取得有效的治疗效果,需要一些主要的治疗障碍。
本年度癌症的治疗重点是,肝细胞癌患者对化疗药物和放射治疗的耐药率较高,而且缺乏治疗手段。
肿瘤在根治性手术切除后复发的频率很高。但目前,没有足够的理由支持这种治疗。
免疫系统干预在肝癌中的应用,但最近的几项临床试验已经证明,免疫治疗的主要好处是。
被降级的癌症患者中只有很小一部分(~20%)的患者,包括这些患有肝癌的患者。这促使他们需要更多的治疗。
更好地了解肝癌、癌症、细胞可塑性和细胞适应的潜在机制,以及。
开发新的治疗方法,以实现对这种疾病更有效的治疗和选择性治疗。
继HSF1之后,作为经典的热休克反应机制的大师和激活者,以及人类蛋白质组的守护者,HSF1已经被证明是正确的。

小鼠肿瘤模型的建立导致了对人肝癌发展的显著的肿瘤抑制作用。
初步研究表明,我们可以提出一种全新的致病机制,通过HSF1的激活促进肝癌的发生。

英文摘要
Among human malignancies, primary liver tumors account for 9% of all cancer deaths worldwide and 12% in
developing countries. HCC accounts for up to 85% of liver cancers and is one of the leading lethal malignancies
worldwide. Chronic liver damage caused by viral infection (HBV and HCV), alcohol, non-alcoholic fatty liver
disease (NAFLD)-associated chronic inflammation, fibrosis, cirrhosis, or a combination of these factors
increases the risk for HCC. Notably, NAFLD, a hepatic manifestation of metabolic syndrome, affects nearly 25%
of the US population, and its incidence is rapidly increasing since obesity and metabolic syndrome are growing
epidemics worldwide. Although the risk factors are well defined, HCC is still an aggressive and difficult-to-treat
malignant disease with poor outcome and limited therapeutic options. In fact, major obstacles for effective
treatment of this cancer is that HCC is frequently resistant to chemotherapy and radiotherapy, and there is a
high frequency of tumor recurrence after curative surgical resection. Currently, there is a strong rationale for
immune intervention in HCC, but recent clinical trials have demonstrated that the benefits of immunotherapy are
relegated to a small fraction (~20%) of cancer patients, including these with HCC. This prompts the need for
greater understanding of the mechanisms underlying liver cancer cell plasticity and adaptation, as well as
developing novel therapeutic approaches to achieve more effective and selective cure of this disease.
Hsf1, as the master activator of the classical heat shock response and guardian of the proteome, has been
implicated in the pathogenesis of cancer. We have discovered that genetic inactivation of Hsf1 in pre-clinical
mouse cancer models leads to remarkable inhibition of HCC development. On the basis of published and
preliminary studies we propose a novel pathogenic mechanism whereby Hsf1 activation promotes HCC
development by stimulating both the protein folding capacity of the cell and regulating anabolic metabolic
pathways, thus perpetuating chronic hepatic metabolic disease. Our recent research revealed that the Hsf1
transcriptional program enables malignant cells to escape immune surveillance. This may provide a new
approach to improve HCC treatment by improving the anti-tumor immune capacity targeting Hsf1 activity. Our
experimental strategy entails the following three major approaches: 1. Determine the impact of hsf1 deletion on
liver cancer initiation and explore its therapeutic implications for advanced HCC, 2. Determine the metabolic and
epigenetic mechanisms by which Hsf1 ablation induces an effective anti-tumor CD8+ T cell response, and 3.
Investigate the impact of Hsf1 deletion on improved CD8+ T cell-based immunotherapy for HCC. In summary,
the long-term translational goal of the project is to test the potential of Hsf1 targeting in human HCC. It will also
provide proof-of-concept for targeting Hsf1-mediated metabolic programs for immunotherapeutic application of
liver cancer.
