eLife:研究人员开发出治疗复发性乳腺癌的新药!

2017-08-31 佚名 Medicalxpress

UT健康圣安东尼奥和两家合作机构的研究人员正在开发一种新的,一流的药物,阻止了雌激素受体阳性(ER阳性)乳腺癌的发展。新药是一种称为ERX-11的分子,阻断了复发性乳腺癌肿瘤的生长。

UT健康圣安东尼奥和两家合作机构的研究人员正在开发一种新的,一流的药物,阻止了雌激素受体阳性(ER阳性)乳腺癌的发展。新药是一种称为ERX-11的分子,阻断了复发性乳腺癌肿瘤的生长。

Ratna Vadlamudi博士是一项研究的主要研究者,负责描述8月8日刊登在eLife杂志上的新发现。他是Joe R.&Teresa Lozano龙医学院妇产科教授,也是UT健康癌症中心癌症发展与进步项目(CDP)的成员。

“女性大多数乳腺癌需要雌激素或孕激素 - 两种雌性激素生长,为了治疗激素依赖性癌症,您必须阻止激素或阻断接受激素的受体,以防止癌症的发展,在许多患者中,肿瘤变得对目前的治疗具有抗性,造成肿瘤复发。我们在UT Health的研究小组发现了一种阻断雌激素受体信号传导的新分子,其发生在抗性肿瘤中,并在实验室的临床前研究中测试了基于分子的药物,”Vadlamudi博士说。

“开发这种药物是重要的,因为它靶向雌激素受体的独特位点,并阻止其与促进乳腺癌进展的关键蛋白质的相互作用。该药物可用于治疗对目前疗法敏感的乳腺癌,”他说。

由Jung-Mo Ahn博士领导的UT达拉斯的研究人员参与了阻断相互作用的药物的合成,由Ganesh Raj医学博士领导的UT西南部的科学家参与机械研究和在涉及原发性乳腺肿瘤的研究中。

Vadlamudi博士说:“用人类乳腺癌细胞植入小鼠通常会使他们发展成乳腺肿瘤,但是当我们给予小鼠ERX-11作为口服药物时,癌症的生长显着减少。在小鼠中的研究显示没有毒性作用,表明基于ERX-11分子的药物将是人类试验的良好候选者。

Vadlamudi博士说:“接下来的步骤是根据FDA的药物开发指南合成药物,并进行正式的毒性研究,以确保药物能够被安全地耐受。 “在进行I期临床试验之前,需要做更多的工作,我们期望人类试验即将开始。”
