概括
环境和生活方式因素对膀癌 (BC) 和上道泌尿道癌 (UTUC) 有不同的影响. LINE-1 DNA甲基化调解了与吸烟相关的BC和UTUC风险,特别是在男性中.
科学领域:
- 在瘤学瘤学.
- 表观遗传学 在表观遗传学中,表观遗传学是指表观遗传学.
- 环境健康 环境健康
背景情况:
- 尿路癌 (UC) 的发展受环境和生活方式因素的影响,但它们在膀癌 (BC) 和上道尿路癌 (UTUC) 中的独特作用以及潜在的表观遗传机制尚未完全理解.
- 调查这些特定位置的风险因素和表观遗传变化对于理解UC癌症发生至关重要.
研究的目的:
- 调查BC和UTUC的特定位置风险因素.
- 探索LINE-1DNA甲基化在UC发育中的调解作用.
- 确定UC预防策略的潜在目标.
主要方法:
- 一项基于医院的病例控制研究,涉及478名UC病例 (266名BC,204名UTUC) 和569名对照.
- 风险因素的评估,包括吸烟,草药使用,并发病,以及血中,和的含量.
- 使用热测序测量LINE-1DNA甲基化,然后进行LASSO和后勤回归来进行风险评估和中介分析.
主要成果:
- 血风险与男性性别,吸烟,慢性病 (CKD),血含量升高和糖尿病有关.
- UTUC风险主要与女性性别和CKD有关.
- LINE-1高甲基化与BC和UTUC风险相关,显著调解吸烟和UC风险之间的关系,特别是在男性中.

Cancer Prevention
6.0K
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.
