概括

这项研究确定了食道癌 (EC) 亚型中的关键基因,揭示了食道腺癌 (EAC) 中的SCARB1等新基因,并突出了MEK抑制剂作为EC的潜在治疗方法.

科学领域:

癌症学
基因组学
生物信息学

背景情况:

食道癌 (EC),包括食道腺癌 (EAC) 和食道状细胞癌 (ESCC),是一种具有有限向治疗的致命疾病.
对于有效的精确药物发现,EC亚型之间的组织学和转录学变异需要亚型特定的分析.

研究的目的:

进行EC的亚型分层转录基因分析以识别差异表达基因 (DEG) 和枢纽基因.
根据转录组形状,探索EAC和ESCC的潜在治疗目标和药物重新利用的机会.

主要方法:

来自GEO和TCGA的综合转录数据,以确定EAC,ESCC和共享配置文件的DEG.
使用功能丰富 (GO,KEGG) 和蛋白质相互作用 (PPI) 网络分析来识别枢纽基因.
使用多种生物信息学工具评估生存关联并进行药物重新定位.

主要成果:

在EAC,ESCC和共享DEG数据集中分别发现了79个,59个和17个枢纽基因.
在EAC中发现了16个新的枢纽基因,富含细胞外矩阵 (ECM) 重塑和上皮结构通路.
在所有DEG数据集中优先考虑MEK抑制剂 (特拉美替尼,塞卢美替尼) 作为潜在的治疗候选药物.

结论:

这项研究提供了EC的亚型分层转录基因框架,识别了与ECM动态相关的独特和共享的枢纽基因.
ECM重塑剂是潜在的治疗点,而MEK抑制是EC的一个有前途的重塑策略.
需要通过蛋白质组分析,功能研究和临床试验进行进一步的验证.

Targeted Cancer Therapies

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Combination Therapies and Personalized Medicine

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Mitogens and the Cell Cycle

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
