概括
这项研究研究了血脂组如何使用孟德尔随机化对6种常见癌症产生影响. 特定的脂质被确定为肝癌,肺癌,结肠直肠癌,食道癌,甲状腺癌和乳腺癌的风险因素或保护剂.
科学领域:
- 遗传学和流行病学
- 生物化学和瘤学
背景情况:
- 血脂层在细胞过程中起着至关重要的作用.

Cancers Originate from Somatic Mutations in a Single Cell
12.7K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

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.
