概括
在原发性前列腺癌中,雄激素受体变体 (ARV) 可能会影响治疗结果. 具体来说,局部前列腺癌中AR-V7的存在与救援放射治疗加上抗雄激素剥夺疗法的反应较差有关.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 遗传学 是一个遗传学.
背景情况:
- 前列腺癌的进展是由雄激素受体 (AR) 信号驱动的.
- 拯救性放射治疗 (RT) 与雄激素剥夺疗法 (ADT) 是复发性前列腺癌的治疗选择.
- 像AR-V7这样的ARRNA拼接变体 (ARVs) 影响转移性前列腺癌的治疗反应.
研究的目的:
- 为了调查是否ARVs在初级前列腺癌影响后的救援结果RT+ADT.
- 确定局部前列腺癌中ARVs (包括AR-V7) 的患病率和预后意义.
主要方法:
- 从43名患者的前列腺切除样本中对AR转录的超深RNA测序.
- 与救援后的结果相关的ARV分析RT+ADT.
- 统计分析包括危险比率 (HR) 和置信区间 (CI).
主要成果:
- 在86%的患者中检测到ARV,平均每患者有3种变体.
- 确定了32种独特的ARV.
- 在14%的患者中存在的AR-V7与第二次生化衰竭的更高风险显著相关 (HR=6.2,p=0.0003).
结论:
- ARVs,特别是AR-V7,可能在局部性前列腺癌中起到调节治疗反应的作用,类似于它们在转移性疾病中的作用.
- 这些发现表明AR-V7是预测局部前列腺癌救援RT + ADT患者预后结果的潜在生物标志物.

RNA Splicing
60.3K
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
24.6K
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...

Abnormal Proliferation
5.1K
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...
