概括
雄激素受体结合变异7 (ARV-7) 阳性发生在亚洲患有转移性割耐性前列腺癌 (mCRPC) 的患者中,其发病率与全球人口相似. ARV-7阳性mCRPC患者表现出更糟糕的结果趋势,这表明疾病更具侵略性.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 遗传学 遗传学是一种遗传学.
背景情况:
- 雄激素受体结合变异7 (ARV-7) 是转移性割抗性前列腺癌 (mCRPC) 激素治疗耐药性的关键机制.
- 全球范围内,ARV-7阳性与mCRPC患者的临床结果较差有关.
- 之前的研究表明,ARV-7阳性的全球发病率在进展到割抵抗后从17.8%到28.8%不等.
研究的目的:
- 为了前性地确定亚洲mCRPC患者ARV-7阳性的发病率.
- 评估ARV-7阳性对这种特定患者群体治疗结果的影响.
- 将亚洲mCRPC患者的ARV-7阳性率与之前报告的全球数据进行比较.
主要方法:
- 从东南亚和东亚中心的mCRPC患者在开始服用雄激素受体信号抑制剂或多塞塔克塞尔之前的潜在招募.
- 在基线评估ARV-7状态,使用三个不同的商业试验:AdnaTest前列腺癌平台,Clearbridge方法和IBN方法.
- 评估临床结果,包括前列腺特异性抗原 (PSA) 反应率,PSA无进展生存率 (PFS) 和进展时的总生存率 (OS).
主要成果:
- 总共分析了102名亚洲mCRPC患者,平均年龄为72岁.
- 在亚洲患者中,ARV-7阳性的发生率从14.3%到33.7%不等,取决于所使用的试验.
- 在基线时ARV-7阳性患者的PSA无进展生存期 (PFS) 与ARV-7阴性患者相比,数值较差.
结论:
- 亚洲mCRPC患者的ARV-7阳性发生率与全球人口中观察到的发生率相当.
- ARV-7阳性似乎与更具侵略性的疾病有关,PSA PFS和整体存活率 (OS) 数字上较差.
- 需要进一步的前性研究,以充分阐明亚洲mCRPC患者ARV-7阳性的预后意义.

RNA Splicing
56.3K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

Alternative RNA Splicing
21.1K
Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...
