概括
氨酸的限制增强了对抗耐药性纤维瘤细胞的特拉贝克提丁疗效. 这种方法在体内显著抑制了瘤的生长,这表明在治疗耐药软组织肉瘤方面进行临床研究的潜力.
科学领域:
- 在瘤学瘤学.
- 癌症生物学 癌症生物学
- 药理学 药理学是指药理学的学科.
背景情况:
- 特拉贝克德丁是一种DNA结合剂,对软组织肉瘤具有中等效果.
- 氨酸的限制先前提高了trabectedin在体外的疗效.
- 纤维瘤细胞发展抵抗力可能会呈现恶性瘤的增加.
研究的目的:
- 为了确定是否特拉贝克丁耐药纤维瘤细胞变得更恶性.
- 评估这些耐药细胞在体内是否保持对 metionin 限制的敏感性.
- 评估 metionin 限制和 trabectedin 对瘤生长的联合作用.
主要方法:
- 通过逐步选择药物,通过逐步选择药物,建立了抗trabectedin的HT1080 (TR-HT1080) 细胞.
- 在体外伤口愈合试验中,评估和比较了HT1080和TR-HT1080细胞的恶性瘤.
- 在体内研究涉及6组TR-HT1080或HT1080瘤的小鼠,接受包括特拉贝克丁在内的治疗和/或甲胺限制饮食.
主要成果:
- 与父母HT1080细胞相比,TR-HT1080细胞在体外和体内显示恶性瘤增加.
- 氨酸限制显著抑制了TR-HT1080瘤的4倍增长.
- metionin 限制和 trabectedin 的组合在体内进行了评估.
结论:
- 耐特拉贝克丁胺纤维瘤细胞获得更高的恶性瘤.
- 氨酸的限制有效地克服了trabectedin在体内的耐药性.
- 对于软组织肉瘤,需要进一步临床研究与特拉贝克丁结合的氨酸限制.

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...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
