含有11氧的雄激素与子宫内膜癌 (EC) 风险有关. 特定的代谢产物,如11-氨和11β-氨,显示出潜在的EC复发和生存的预后标志物.
科学领域:
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
- 代谢学 代谢学 代谢学
背景情况:
- 雄激素在子宫内膜癌 (EC) 病因学中发挥作用.
- 11-氧化雄激素是强大的雄激素受体激动剂,但它们在EC中的作用尚未研究.
研究的目的:
- 为了研究11-oxygenated雄激素在绝经后子宫内膜癌中的作用.
- 评估11-氧化作为EC的潜在预后标志物.
主要方法:
- 研究了272个绝经后的EC病例.
- 使用LC-MS/MS测量了手术前和后7种11氧化原体 (自由和总) 的血清度.
- 分析了与临床病理特征,复发和无病生存率 (DFS) 的关联.
主要成果:
- 11氧化的雄激素与和二二的相关性很弱.
- 手术后水平下降,但在超重/肥胖患者中仍然较高.
- 在手术前,自由的11-基托安德罗 (11KAST) 与复发风险增加有关 (HR=2.99).
- 手术后免费的11β-氨 (11OHAST) 与不良反应复发和DFS相关 (HR=3.23,HR=3.27).
结论:
- 11氧化代谢物是子宫内膜癌的潜在预后标志物.
- 特定的代谢物可以预测EC患者的复发和无病生存期.

Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...
Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
