概括
乳腺癌和周围的脂肪组织表现出同步的代谢变化,特别是在绝经前妇女中. 肥胖影响瘤和脂肪组织中的线粒体代谢,影响乳腺癌的进展.
科学领域:
- * 瘤学 在线咨询
- * 代谢研究研究
- * 绝经前的乳腺癌
背景情况:
- * 乳腺癌和与癌症相关的脂肪组织 (CAAT) 之间的相互作用影响瘤行为.
- *线粒体新陈代谢和肥胖在绝经前乳腺癌中的特定作用尚未完全理解.
研究的目的:
- * 为了研究 mitochondrial 代谢动力学,对结合恶性和良性乳腺瘤组织和 CAAT.
- * 为了比较正常体重和超重/肥胖的绝经前妇女之间的这些动态.
主要方法:
- * 分析来自恶性和良性乳腺瘤和相邻的CAAT的配对活检.
- * 评估关键代谢酶 (如酸盐脱酶,酸盐合成酶,β-氧化,脂肪酸合成酶,电子运输链复合体) 的蛋白质水平.

Adaptive Mechanisms in Cancer Cells
5.8K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

The Tumor Microenvironment
6.6K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
