概括

不同于ERα,非小细胞肺癌 (NSCLC) 的雌激素受体β (ERβ) 表达与更好的生存率有关. 对于肺癌患者来说,ERβ可能是一个有前途的治疗点.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
内分泌学在内分泌学.

背景情况:

雌激素受体 (ERs),包括ERα和ERβ,存在于肺癌中.
在非小细胞肺癌 (NSCLC) 中ERα和ERβ的预后价值尚未确立.
了解ER表达可能会揭示NSCLC的新治疗策略.

研究的目的:

确定ERα和ERβ在NSCLC中的综合流行率.
评估ERα和ERβ表达对NSCLC患者存活率的预后意义.
调查ER表达和结果的潜在性别特异性差异.

主要方法:

从主要数据库中对18项研究 (3842名患者) 的系统审查和元分析.
用总生存率 (OS) 的95%置信区间 (CI) 计算危险比率 (HRs).
随机效应模型被用于分析关联,评估异质性和出版偏差.

主要成果:

在32%的NSCLC病例中发现了ERα,与OS没有显著的关联 (HR 1.17).
在60%的NSCLC病例中发现了ERβ,并且与降低死亡风险显著相关 (HR 0.85,p=0.04).
与女性相比,男性的死亡风险较高 (HR 1.42).

结论:

在NSCLC中高ERβ表达与改善的生存结果相关.
ERα表达不太常见,其预后影响不确定.
在NSCLC中,ERβ是潜在的治疗点,因此需要对激素向治疗进行进一步的研究.

Internal Receptors

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Transducer Mechanism: Nuclear Receptors

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Cancer Survival Analysis

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...
