概括
结合表观遗传学,基因表达和组织学,一种新的多原子生物标志物签名可以根据烟草使用史准确预测口腔状细胞癌 (OSCC) 患者的死亡率.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 生物标志物发现发现
背景情况:
- 口腔状细胞癌 (OSCC) 死亡率预测往往缺乏全面的多组策略.
- 将临床病理学因素与多原子数据相结合,可以提高预后准确性.
研究的目的:
- 开发和验证一种新的生物标志物签名,用于预测OSCC患者的死亡率.
- 根据烟草使用史区分OSCC患者,使用综合表观遗传,基因表达和组织学特征.
主要方法:
- 利用癌症基因组图谱 (TCGA) 和内部队列进行分析.
- 在从不吸烟者和重度吸烟者 (≥10包年) 之间确定了差异表达的表观遗传和基因标记物.
- 开发了一种结合的签名,包括表观遗传,基因表达和组织学数据,用于死亡率预测.
主要成果:
- 根据吸烟史,在OSCC患者中鉴定了3种表观遗传标记 (GPR15,GNG12,GDNF) 和13种表达标记的失调调.
- 仅使用吸烟状况和临床病理共变量的模型显示死亡率预测不佳 (c-统计 = 0.57).
- 结合表观遗传,表达和组织学特征,实现了0.9409的高c统计值,用于预测5年OSCC死亡率.
结论:
- 综合表观遗传学,基因表达和组织学的多原子生物标志物签名显著改善了OSCC的5年死亡率预测.
- 这种新型的签名为OSCC患者提供了更准确的预后工具,特别是基于烟草暴露的差异化.
- 未来的研究应该验证这个签名在OSCC管理中的临床应用.

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

Mouse Models of Cancer Study

Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
