概括

主导阴性TP53突变加剧了转移性割敏感前列腺癌 (mCSPC) 的结果. 治疗APR-246抵消了这些影响,显示了mCSPC患者TP53突变的治疗潜力.

科学领域:

在瘤学瘤学.
遗传学是一个遗传学.
癌症生物学癌症生物学

背景情况:

在许多癌症中TP53突变是常见的,但它们对转移性割敏感前列腺癌 (mCSPC) 进展和转移的具体影响尚不清楚.
了解TP53突变的表型影响对于开发mCSPC的向疗法至关重要.

研究的目的:

描述mCSPC中TP53突变的结构功能和临床影响.
研究APR-246在抵消前列腺癌中TP53突变的影响方面的潜力.

主要方法:

根据TP53突变状态和转移负担分层进行下一代测序的mCSPC患者的国际回顾.
使用卡普兰-梅尔和多变量考克斯回归,评估无放射性进展生存率 (rPFS) 和整体生存率 (OS).
使用同源细胞系进行体外和体内研究,以评估TP53突变和APR-246对癌细胞迁移,入侵,殖民地形成和瘤生长的影响.

主要成果:

主导阴性 (DN) TP53突变在同步和多转移性疾病患者中显著丰富.
与TP53野生型 (WT) 相比,DN TP53突变与明显更糟糕的RPFS和OS有关.
在实验室中,TP53突变细胞的迁移,入侵和殖民地形成增加;APR-246逆转了这些影响,并在体内抑制了瘤生长.

结论:

DN TP53突变与前列腺癌的预后较差和转移潜力增加相关.
APR-246显示出作为治疗剂的潜力,可以抵消mCSPC中TP53突变的负面影响.
用像APR-246这样的药物向TP53突变代表了对mCSPC的有希望的未来治疗策略.

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...

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
