概括
克劳丁3 (CLDN3) 在肺癌中经常表达,在腺癌中,其水平高于状细胞癌. 减少CLDN3的表达与两个肺癌亚型的更差的预后相关.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 癌症研究 癌症研究
背景情况:
- 克劳丁3 (CLDN3) 是一种跨膜蛋白质,对紧密的结节至关重要.
- 它的膜性定位使得CLDN3成为潜在的治疗点.
- 改变CLDN3表达被认为是包括肺癌在内的各种癌症的预后标志物.
研究的目的:
- 调查不同肺癌亚型中CLDN3表达的患病率和预后意义.
- 为了将CLDN3表达水平与临床病理特征和患者生存率相关联.
主要方法:
- 免疫组织化学被用来评估CLDN3的表达.
- 这项研究使用组织微阵列分析了858个切除的肺癌样本的队列.
主要成果:
- 与状细胞癌 (53.3%) 相比,LCDN3阳性在腺癌 (95.9%) 中显著更高.
- 在这两种亚型中,降低CLDN3染色与晚期瘤阶段,结节转移和阳性切除边缘 (R+状态) 相关.
- 缺失或减少CLDN3表达与肺腺癌和状细胞癌的总生存时间显著缩短相关.
结论:
- 肺癌中CLDN3表达很普遍,在腺癌中观察到更高的水平.
- 减少CLDN3表达是两个主要肺癌亚型不良预后的指标.
- 非小细胞肺癌 (NSCLC) 可能是未来抗CLDN3向治疗的重要领域,药物安全性和有效性尚未确定.

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...

02:17The Tumor Microenvironment
7.6K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
