概括
早期的恩扎胺治疗可以提高前列腺癌的免疫反应,但耐药性会导致免疫力和可塑性受到抑制. 将恩扎胺与STAT抑制剂结合使用可能会防止耐药性.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 免疫学 免疫学 免疫学
背景情况:
- 安卓素受体 (AR) 抑制剂,如恩扎胺,可以将前列腺癌驱动到神经内分泌前列腺癌 (NEPC).
- 免疫信号在恩扎拉胺诱导的血统可塑性中的作用尚不清楚.
研究的目的:
- 在前列腺癌进展过程中调查恩扎胺对免疫信号通路的影响.
- 探索向免疫通路的潜力,以克服酶胺耐药性和血统可塑性.
主要方法:
- 患者样本和细胞系的转录学分析.
- 对干扰素 (IFN) 和介质白素 (IL) 信号通路的评估 (IFNγ,IFNα,IL6-JAK-STAT3).
- 用fludarabine评估细胞因子反应和STAT1抑制的功能测试.
主要成果:
- 免疫通路 (IFNγ,IFNα,IL6-JAK-STAT3) 在NEPC和酶胺耐药细胞中被抑制.
- 早期的甲胺治疗增强了IFNγ和IL6的反应能力,并激活了JAK/STAT信号传递.
- 早期细胞对STAT1抑制表现出敏感性,这种敏感性在耐药细胞中消失.
结论:
- 恩扎胺最初增强了免疫反应,但抵抗涉及免疫抑制和可塑性.
- 有一种治疗窗口可以将恩扎胺与STAT抑制剂结合起来,以防止耐药性和可塑性.

Treatment Resistant Cancers
3.7K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

mTOR Signaling and Cancer Progression
4.6K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
