HSP70是一种关键的癌症关键的蛋白质组,它是在一个强调的过程中保持适当的蛋白质和折叠结构的必要物质。
细胞。我们的HSP70家族包含了超过8个家族成员。这是我们研究的第一个家族成员,也是我们的主要压力之一。
诱导家族成员HSPA1A,以下简称HSP70。与其他家族成员不同的是,这个新的蛋白家族成员并不过度表达。
在超过75%的转移性黑色素瘤中,癌症和癌症与药物耐药性和患者较差的生存有关。
多年来,我们已经开发出了一系列针对HSP70应激诱导基因形式的药物抑制剂,而不是针对其他家族的药物。
成员们喜欢Hsc70和GRP75。此外,我们最近注意到,位于该网站的HSP70中有相当大的一部分。
线粒体是肿瘤的一部分,但不是正常的细胞的一部分,我们和我们的细胞抑制剂结合在一起,形成了一种新的三苯基膦。
帮助我们将这些化合物直接作用于线粒体。在过去的一个资金周期中,我们测试了这种化合物对线粒体的作用。
黑色素瘤、癌症和其他疾病解决了药物作用的晶体结构和机制问题。在当前的新一轮资助周期中,我们应该采取措施。
我们最新的新型药物-线粒体导向的HSP70受体抑制剂-的更新和更强大的药物衍生品可能成为最难治疗的药物。
黑色素瘤亚型:那些对BRAF/MEK抑制剂不耐药的人,以及那些患有野生型BRAF和BRAF的人。
NRAS(WT/WT),以及那些已经转移到脑部的人(黑色素瘤或脑转移瘤,或MBMS)。
针对这三大类药物,为临床带来重大影响提供了潜在的支持,并为我们提供了初步的临床数据和支持。
HSP70i的使用有助于区分这些主要的肿瘤亚型。在我们提出的新工作中,我们可以广泛合作,与我们的HSP70i合作。
同事们希望首次探讨HSP70i对包括癌症在内的肿瘤微环境的影响。
癌症与成纤维细胞和衰老的微环境有关。我们还将专注于推出几个全新的HSP70客户。
包括ErbB3、ID3和Gpx4。为了更好地实现这些目标,我们必须建立一支在HSP70方面是专家的团队。
以及蛋白质抑制疗法(墨菲和乔治),药物化学疗法(萨尔维诺),以及治疗脑转移的微生物学研究。
环境科学(陈)。我们可以预计,该公司提出的新研究计划将产生HSP70i的候选药物,用于临床药物的开发、研究和开发。
为了更好地为那些最难治疗的黑色素瘤亚型提供一个重要的治疗方案。
英文摘要
Project Summary – Project 3
HSP70 is a key cancer-critical survival protein that is necessary to maintain proper protein folding in a stressed
cell. The HSP70 family contains more than eight family members. The one under study here is the major stress-
induced family member HSPA1A, hereafter HSP70. Unlike other family members, this protein is overexpressed
in over 75% of metastatic melanoma, and is associated with drug resistance and poor survival. In the past ten
years we have developed a series of inhibitors that target the stress-induced form of HSP70 but not other family
members like Hsc70 and GRP75. Additionally, we recently noted a significant fraction of HSP70 located at the
mitochondria of tumor but not normal cells, and we coupled our inhibitors to a triphenylphosphonium moiety that
helps direct these compounds to mitochondria. In the past funding cycle we tested this compound against
melanoma, and solved the crystal structure and mechanism of action. In the current funding cycle, we take
newer and more potent derivatives of our novel mitochondria-directed HSP70 inhibitors to the toughest-to-treat
subtypes of melanoma: those that are resistant to BRAF/MEK inhibitors, those that have wild type BRAF and
NRAS (WT/WT), and those that have metastasized to the brain (melanoma brain metastases, or MBMs).
Targeting these three categories has the potential for significant clinical impact, and our preliminary data support
the use of HSP70i for these tumor sub-types. In the proposed work we collaborate extensively with our P01
colleagues to explore for the first time the impact of HSP70i on the stressed tumor microenvironment, including
cancer associated fibroblasts and the aged micro-environment. We also focus on several new HSP70 clients,
including ErbB3, ID3 and GPX4. To succeed in these goals, we have accrued a team that is expert in HSP70
and proteostasis (Murphy and George), medicinal chemistry (Salvino) and the brain metastatic micro-
environment (Chen). We expect the proposed research to yield candidate HSP70i for clinical development, and
to provide an important therapeutic option for the toughest-to-treat melanoma sub-types.
