概括
孕激素受体 (PGR) 和雄激素受体 (AR) 信号是良性前列腺增生症 (BPH) 中前列腺体积大的主要因素. 这些受体与雌激素受体 (ER) 和前列腺特异抗原 (PSA) 一起影响前列腺大小.
科学领域:

- 内分泌学 在内分泌学.
- 分子生物学分子生物学
背景情况:
- 良性前列腺增生症 (BPH) 是老年男性常见的疾病.
- 大前列腺体积 (≥80毫升) 和雄激素受体 (AR) /前列腺特异抗原 (PSA) 在BPH中的信号传递之间的关系尚不清楚.
- 研究激素受体在BPH发病过程中的作用对于了解疾病进展至关重要.
研究的目的:
- 确定孕激素受体 (PGR),雄激素受体 (AR),雌激素受体α (ERα),雌激素受体β (ERβ) 和前列腺特异性抗原 (PSA) 是否有助于BPH中大前列腺的发展.
- 阐明在BPH中前列腺扩大背后的分子机制.
主要方法:
- 针对不同前列腺大小小组的人类BPH手术样本的免疫组织化学和组织微阵列分析 (平均体积:25.97毫升,63.80毫升,122.37毫升).
- 与前列腺体积相关的PGR,AR,PSA和ERα,β表达水平的分析.

Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
