尽管经过了半个世纪的社会和经济投资,
以及它们的途径,以及一系列新的分子和免疫疗法,
仍然有很高的发病率和死亡率。被誉为癌症“治疗”的突破,
个性化医疗,每个患者都可以根据不同的癌症类型接受合适的药物,
基因构成还有待了解。事实上,大多数分子靶向药物在
诊所,只产生短暂的反应,往往在惊人的费用和经济困难的病人,
只会被抗药性和转移性疾病的出现所取代。我们知道
人类肿瘤的异常异质性,数百个恶性克隆不断竞争,
相互合作,是治疗失败的一个主要原因,但对这一点的深入了解,
这个过程仍然令人惊讶地难以捉摸。我们小组在过去十年中开展的工作重点是

英文摘要
PROJECT SUMMARY
Despite half a century of social and economic investments, an unprecedented understanding of cancer genes
and their pathways, and an arsenal of new molecular and immunological therapies, a diagnosis of malignancy
still carries significant morbidity and mortality. Heralded as a breakthrough for cancer “cures”, the promise of
personalized medicine, where every patient receives the right drug for the right type of cancer based on
genetic makeup is yet to be realized. In fact, most molecularly-targeted drugs have been disappointing in the
clinic, producing only short-lived responses, often at staggering costs and financial hardship for the patients,
only to be supplanted by the emergence of drug-resistant and metastatic disease. We know that the
extraordinary heterogeneity of human tumors, with hundreds of malignant clones in constant competition and
cooperation with each other, is a major reason for treatment failure, but an in-depth understanding of this
process has remained surprisingly elusive. Work carried out by our group over the past ten years has focused
on mechanisms of tumor adaptation, or plasticity as novel, fundamental drivers of disease heterogeneity and
worse patient outcome. We found that stress conditions typical of the tumor microenvironment, whether
hypoxia, shortage of nutrients, protein toxicity or exposure to molecular therapy activate a coordinated set of
cellular responses, a network that sustains cell proliferation, promotes survival, reconfigures metabolism,
stimulates gene expression, and heightens cell motility and invasion. The net effect for the malignant
population is not only improved fitness to cope with an unfavorable microenvironment, but also the acquisition
of new traits characteristic of aggressive disease, including drug-resistance and metastatic competence.
Unexpectedly, we identified reprogramming of mitochondrial functions as an obligatory hub for this process,
enabling organelle-cytoskeleton dynamics, assembly of novel apoptosis-regulatory complex(es), and
retrograde gene expression. Therefore, the hypothesis that tumor plasticity imparts cellular diversity in
response to stress, propagates tumor heterogeneity and promotes the acquisition of aggressive disease traits
through mitochondrial reprogramming can be formulated, and will constitute the focus of the present
application. The proposed studies will dissect the cellular and molecular requirements of tumor plasticity as a
novel hallmark of cancer, credential its relevance in xenograft and genetic mouse models of localized and
metastatic disease, and exploit emerging vulnerabilities of these pathways for innovative cancer drug
discovery. The results will establish tumor plasticity as a novel driver of disease progression, reach a
comprehensive blueprint of the role of mitochondrial homeostasis in cancer, and validate new, actionable
therapeutic targets for patients with late-stage disease.
