概括
鼻癌 (NPC) 中的自相关基因 (ATG) 表达与爱斯坦-巴尔病毒 (EBV) 状态和临床结果相关. 升高的ATG4B和ATG4D与转移的减少有关,而ATG4D影响远程无转移的存活率.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 免疫学 免疫学 免疫学
背景情况:
- 自途径的组成部分与癌症预后有关,但它们在鼻癌 (NPC) 临床结果中的确切作用尚不清楚.
- 爱斯坦-巴尔病毒 (EBV) 感染是NPC的已知风险因素,其与细胞过程 (如自) 的相互作用需要调查.
研究的目的:
- 调查NPC中自相关基因 (ATG) 的mRNA和蛋白质表达水平.
- 确定ATG表达与EBV感染的关联,NPC患者的临床病理特征和临床结果.
主要方法:
- 分析了35个NPC FFPE组织样本和5个非癌性鼻膜粘膜对照.
- 定量PCR (qPCR) 用于9个ATG的mRNA表达.
- 对于ATG的蛋白质表达的免疫组织化学.
主要成果:
- 在EBV阳性NPC中,ATG3,ATG4D,ATG4C,ATG4A,ATG2B和ATG5mRNA水平显著更高.
- ATG3和ATG4C蛋白表达与EBV阳性有很强的相关性 (P = 0.002).
- 增加的ATG4B和ATG4D表达与远程转移减少相关 (P = 0.019),而减少的ATG4DmRNA与较短的远程转移无生存时间 (DMFS) 相关联.
结论:
- 与自相关的基因表达受到NPC中的EBV状态的显著影响.
- 特定的ATG,特别是ATG4B和ATG4D,显示出作为预测NPC转移和生存的生物标志物的潜力.
- 评估ATG表达为预测NPC临床结果提供了一种有价值的方法,值得进一步研究治疗应用.

01:51Mechanisms of Retrovirus-induced Cancers
5.3K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

01:29Immune Response Against Viral Pathogens
931
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

4.6K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...
