概括

与甲基二酸 (Yunke) 结合的非放射性技术-99通过抑制骨质细胞活性,而不是瘤细胞增殖,促进骨转移中的骨修复. 推Yunke促进修复和延迟骨转移的进展.

科学领域:

在瘤学瘤学.
放射性药物放射性药物放射性药物
骨生物学骨生物学骨生物学

背景情况:

骨转移 (BM) 在癌症治疗中构成重大挑战,往往导致疼痛和骨相关事件.
非放射性技术-99与甲基二酸 (⁹⁹Tc-MDP) 结合,品牌为Yunke,正在研究其对BM的影响.

研究的目的:

为了研究云克对骨转移的止痛作用和骨修复机制.
阐明云克对原发性瘤细胞和骨质细胞相关细胞的影响.

主要方法:

在体内研究中,使用了与Yunke或其成分治疗的小鼠前列腺癌骨转移模型.
在体外实验中评估了Yunke对RM-1癌细胞和骨髓衍生细胞的影响,使用CCK8,划痕,亡,PCR和西部Blot测定.
在瘤样本上进行了组织病理学,微型CT和X射线分析.

主要成果:

云克并没有影响主要瘤的大小或扩散,但在骨转移性病变中增强了亡.
在体外,Yunke没有抑制RM-1细胞的增殖或迁移,但促进了晚期的亡.
克抑制了骨髓衍生的细胞增殖,骨质细胞分化以及相关的信号通路 (MAPK) 和转录因子,导致骨质再吸收减少和骨质量改善.

结论:

克不推用于治疗原发性瘤或预防骨转移的发生,因为它缺乏对癌细胞的抗增殖作用.
云克对骨转移的治疗作用源于抑制骨质细胞的分化和活性,从而促进骨的修复和防止骨破坏.
云克适用于促进现有的骨转移的修复,延迟进展,减少骨相关事件.

关键词:

在99Tc-MDP中.一个RM-1就是一个RM-1.骨转移发生在骨髓中.分子机制的分子机制.前列腺癌是前列腺癌.

Targeted Cancer Therapies

Targeted Cancer Therapies

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.
There are several types of targeted therapies against...

Non-Canonical Wnt Signaling Pathways

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

Canonical Wnt Signaling Pathway

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...
