概括

在直肠瘤中,微管相关蛋白1轻链3α (LC3A) 的石状结构 (SLS) 的存在表明预后较差. 这种自性标记物是自性标记物.

科学领域:

细胞生物学细胞生物学
在瘤学瘤学.

背景情况:

自是一种细胞降解过程,对细胞存活至关重要,并与瘤进展有关.
微管相关蛋白1轻链3α (LC3A) 是自细胞形成的关键标志物.

研究的目的:

为了研究直肠癌中LC3A的表达模式.
确定直肠癌中LC3A表达的临床病理学意义和预后价值.

主要方法:

用免疫组织化学分析了243名直肠癌患者的瘤样本中的LC3A表达.
使用卡普兰-梅尔生存分析和考克斯回归来评估预后价值.

主要成果:

确定了三个LC3A表达模式:分散的细胞质,周核和石状结构 (SLS).
在瘤外围的LC3ASLS阳性与明显更差的整体存活率 (OS) 和无病存活率 (DFS) 相关.
这种关联在患有晚期瘤阶段 (T3-T4) 的患者中尤为明显.

结论:

在瘤外围的LC3A SLS可以作为一个有价值的生物标志物来预测直肠癌的生存结果.

lncRNA - Long Non-coding RNAs

lncRNA - Long Non-coding RNAs

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...
