概括
研究人员确定了外体胰岛素样生长因子结合蛋白7 (IGFBP7) 和Annexin A1 (ANXA1) 作为用于非侵入性检测喉平细胞癌 (LSCC) 和其阶段的有希望的生物标志物. 建议在更大的患者群体中进一步验证.
科学领域:
- 生物化学 生物化学
- 在瘤学瘤学.
- 生物标志物发现发现
背景情况:
- 喉平细胞癌 (LSCC) 缺乏有效的查方法.
- 早期诊断对于LSCC治疗和患者的治疗结果至关重要.
- 识别非侵入性生物标志物可以提高诊断准确性和分期.
研究的目的:
- 为了发现LSCC检测的外体血清生物标志物.
- 要区分早期和晚期的LSCC.
- 建立用于喉癌的非侵入性诊断工具.
主要方法:
- 来自LSCC患者和对照组的外体的蛋白质组阵列分析.
- 生物统计分析以确定重要的蛋白质候选者.
- 使用免疫组织化学 (IHC),西部斑块 (WB) 和ELISA进行验证.
主要成果:
- 外体IGFBP7和ANXA1表现出显著的差异性表达.
- 这些生物标志物有效地将LSCC患者与对照患者区分开来 (p < 0.001).
- IGFBP7和ANXA1也区分了早期和晚期的LSCC阶段 (折叠变化高达15.9).
结论:
- IGFBP7和ANXA1是LSCC的潜在的非侵入性生物标志物.
- 外体生物标志物在整个血清中提供了更好的信号噪声比.
- 为了在喉癌分析中临床应用,需要进行更大的队列验证.

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...

Overview of Exosomes
2.7K
Exosomes are stable, lipid bilayer-enclosed vesicles capable of crossing biological barriers. They can carry a wide range of molecules required for intercellular communication. Once exosomes are released from the cell where they originated, they enter a recipient cell through various pathways such as fusion, receptor-mediated endocytosis, macropinocytosis, and phagocytosis.
