概括
患有淋巴血管菌病 (LAM) 的患者面临患肺癌的风险显著增加. 这种与TSC1/TSC2基因相关的罕见肺部疾病,需要进一步调查其与肺癌发展的联系.
科学领域:
- 在瘤学瘤学.
- 肺部病理学 肺部病理学
- 罕见疾病 罕见疾病
背景情况:
- 淋巴细胞结核病 (LAM) 是一种罕见的瘤疾病,与TSC1和TSC2瘤抑制基因有关.
- LAM导致肺部破坏,可能增加肺癌风险,尽管由于LAM的稀有性,这种联系尚未得到充分证实.
研究的目的:
- 在被诊断为LAM的患者中调查肺癌的相对风险.
- 分析LAM与随后的肺癌发展之间的关联.
主要方法:
- 在日本对642名LAM患者 (2001-2022) 的回顾性队列研究.

Non-LTR Retrotransposons
11.5K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Cancer Prevention
6.2K
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.

lncRNA - Long Non-coding RNAs
8.6K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
