概括
将多种ADP-ribose聚合酶抑制剂 (PARPi) 与雄激素受体信号抑制剂 (ARSI) 结合起来,在前列腺癌 (PCa) 中显示出可变的疗效. 虽然BRCA突变的PCa受益最多,但非同类修复缺陷 (非HRD) 队列显示有争议的结果,需要进一步研究优化治疗策略.
科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 前列腺癌 (PCa) 是西方国家癌症死亡的主要原因,针对性治疗选择有限,特别是化疗后的进展.
- 向疗法可降低毒性,这对于老年PCa患者群体至关重要.
研究的目的:
- 审查当前关于将多ADP-ribose聚合酶抑制剂 (PARPi) 与雄激素受体信号抑制剂 (ARSI) 结合用于前列腺癌 (PCa) 的证据.
- 探索这些组合的潜力,超出了已确定的DNA修复缺陷的患者.
- 为PCa治疗的未来研究和临床实践提供信息.
主要方法:
- 在PubMed,EMBASE和Medline索引的出版物的综合文献综述.
- 专注于前列腺癌遗传学,PARPi机制以及临床前/临床数据.
- 对PARPi和ARSI联合治疗结果的分析.
主要成果:
- PARPi/ARSI组合在前列腺癌 (PCa) 中产生可变的反应.
- 与BRCA突变的PCa显示出一致的积极结果.
- 具有其他同源修复缺陷 (HRD) 的PCa显示较少的益处,而非HRD队列中的疗效仍在争论中.
结论:
- 必须平衡PARPi/ARSI组合的治疗益处与增加的毒性.
- 未来的研究应该优先发展可容忍的PARPi,优化组合策略,并完善DNA修复缺陷的诊断工具.
- 确定PCa中PARPi反应的分子驱动因素对于个性化治疗至关重要.

Targeted Cancer Therapies
7.8K
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.

Long-patch Base Excision Repair
7.2K
Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Base Excision Repair
23.0K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.

DNA Damage can Stall the Cell Cycle
9.3K
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...

Treatment for Pulmonary Arterial Hypertension: Prostacyclin Receptor Agonists
259
Prostacyclin receptor agonists are a class of therapeutic agents integral to managing pulmonary arterial hypertension (PAH). These drugs operate by mimicking the action of prostaglandin I2, or PGI2, a naturally occurring compound in the body.
These agonists bind to the IPR receptor situated on the plasma membrane of the pulmonary artery smooth muscle cells. This binding triggers a cascade of reactions known as the GS-AC-cAMP-PKA pathway. This pathway results in the relaxation of smooth muscle...
