概括

脱氨 (DHEA) 和其硫酸盐形式 (DS) 可能抑制各种癌症. 虽然在乳腺癌患者中升,但DHEA的使用显示出对瘤发育和生长的保护作用.

科学领域:

内分泌学在内分泌学.
在瘤学瘤学.
癌症生物学癌症生物学

背景情况:

在乳腺癌患者中,预先诊断的血清脱氨 (DHEA) 和DHEA硫酸盐 (DS) 的水平升高.
上腺类固醇含量增加,包括皮质醇,与乳腺癌有关,这表明存在潜在的因果关系.
存在相互矛盾的发现,因为DHEA在动物模型中已经证明了对各种癌症的保护作用.

研究的目的:

研究DHEA及其衍生物在抑制癌症中的潜在作用.
探索这样的假设:在癌症的背景下,高血糖皮质激素,而不是DHEA或DS,是有害的.
阐明DHEA发挥抗癌作用的机制.

主要方法:

在癌症的动物模型中对DHEA的管理进行现有研究的审查.
对DHEA对激素敏感和激素独立癌症的影响的分析.
检查DHEA抗瘤活性背后的分子机制.

主要成果:

在动物中,DHEA的使用抑制了自发性,病毒性,致癌物诱导和辐射诱导的乳腺癌.
在肺,肝,结肠,前列腺,淋巴和皮肤癌模型中,DHEA抑制了瘤的发展.
DHEA对抗雌激素对人类乳腺癌移植的作用,并促进雌激素受体β表达.

结论:

DHEA及其衍生物在各种癌症类型和起源中显示出抑制癌症的前景.
与增加上腺类固醇相关的有害成分可能是葡萄糖皮质类固醇,而不是DHEA或DS.
机制包括抑制葡萄糖-6-酸盐脱酶,胆固醇生物合成,IL-6和增强自然杀手细胞活性.

Cancer Prevention

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Mitogens and the Cell Cycle

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
