概括
乳酸可能会增加非小细胞肺癌 (NSCLC) 的风险,通过通过基因素乳化降低hexokinase 1 (HK1) 的调节. 较高的HK1表达与降低NSCLC风险有关,这表明它具有保护作用.
科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 代谢过程中的代谢.
背景情况:
- 非小细胞肺癌 (NSCLC) 是癌症死亡的主要原因.
- 赫索金酶1 (HK1) 在细胞代谢和癌症进展中发挥作用.
- 在各种癌症中观察到乳酸积累,但其在NSCLC的因果作用尚不清楚.
研究的目的:
- 通过使用孟德尔随机化 (MR) 调查赫索金酶1 (HK1) 与非小细胞肺癌 (NSCLC) 风险之间的因果关系.
- 探索乳酸诱导下调HK1的潜在机制,通过NSCLC中通过基因素乳酸化.
- 评估HK1作为对NSCLC的潜在保护因素和乳酸作为危险因素.
主要方法:
- 利用全基因组关联研究 (GWAS) 对HK1和NSCLC的总结统计.
- 采用孟德尔随机化 (MR) 分析与反变量加权 (IVW) 作为主要方法.
- 应用了补充MR方法 (MR-Egger,加权中位数等). 和灵敏度分析 (异质性,性,留出一个) 确保稳定性.
主要成果:
- 基因预测较高的HK1表达与NSCLC风险降低显著相关 (OR=0.93,P<0.05).
- 基因预测HK1表达的每一个单位增加对应于NSCLC几率大约下降7%.
- 没有检测到显著的异质性或定向性,支持MR分析的有效性.
结论:
- 这项MR研究提供了遗传证据,表明乳酸可能通过基因素乳化降低HK1的表达,从而增加NSCLC的风险.
- HK1似乎是对NSCLC的保护因素.
- 局限性包括祖先限制和潜在的残留类,需要进一步验证.

lncRNA - Long Non-coding RNAs
9.8K
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...

Adaptive Mechanisms in Cancer Cells
6.9K
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,...
