概括
高MAL2表达表明三阴性乳腺癌 (TNBC) 患者的预后不佳. 这一发现在多个患者队列中是一致的,突出显示MAL2是TNBC的潜在预后生物标志物.
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:
- 由于缺乏向受体,三阴性乳腺癌 (TNBC) 存在治疗挑战.
- 过度表达MAL2蛋白与内细胞分裂和对新兴癌症治疗的抗性有关.
- 了解TNBC的预后标志物对于改善患者的治疗结果至关重要.
研究的目的:
- 调查MAL2表达在三阴性乳腺癌的预后意义.
- 确定MAL2,PD-1/PD-L1和TNBC中的临床病理特征之间的关系.
- 评估MAL2作为TNBC患者生存的潜在生物标志物.
主要方法:
- 对来自76名患者的111个TNBC样本中的MAL2和PD-1表达的免疫组织化学分析.
- 使用癌症基因组图谱 (TCGA) 队列进行生存分析的验证.
- 与临床病理学变量和患者存活率相关的MAL2表达的统计评估.
主要成果:
- 高MAL2表达与TNBC患者的5年生存率较低显著相关 (71.33%与89.59%对比).
- 在组织微阵列和TCGA队列中,低MAL2表达预测了更长的整体和疾病特异性生存时间.
- MAL2表达独立于PD-1水平和常见的TNBC临床病理特征,但与BRCA TCGA队列中的年龄相关.
结论:
- 提高MAL2表达是三阴性乳腺癌不良预后的独立预测因子.
- 在TNBC中MAL2的预后值不受PD-1表达或标准临床病理参数的影响.
- 马尔2值得进一步研究,因为它是TNBC的潜在治疗标或预后生物标志物.

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...

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
