概括

腺酸酶7 (AK7) 是清细胞细胞癌 (ccRCC) 的潜在生物标志物. 低AK7表达与预后不佳和免疫疗法的有效性降低相关,但增强AK7增强了抗PD1治疗反应.

科学领域:

在瘤学瘤学.
分子生物学分子生物学
免疫治疗是一种免疫疗法.

背景情况:

清细胞细胞癌 (ccRCC) 由于微妙的早期症状,高复发率和对传统治疗的耐药性而带来挑战.
对于有效的ccRCC管理,迫切需要新的治疗目标.

研究的目的:

调查腺酸酶7 (AK7) 作为ccRCC中的预后生物标志物和治疗标的作用.
评估AK7表达对ccRCC细胞行为的影响和免疫疗法的有效性.

主要方法:

使用TCGAportal和UALCAN数据库对ccRCC组织中AK7表达的分析.
在体外评估AK7对ccRCC细胞增殖,入侵和迁移的影响.
使用CANCERTOOL和Kaplan-Meier绘图器对AK7表达与患者预后和免疫治疗反应的相关性分析.
通过TISIDB数据库调查AK7与免疫标记物的关系.
在ccRCC动物模型中对联合AK7过度表达和抗PD1治疗的体内评估.

主要成果:

在ccRCC组织中观察到低AK7表达,与较差的整体存活率 (OS) 相相关.
AK7表达显著影响了ccRCC细胞的增殖,入侵和迁移.
低AK7表达与CD8+T细胞枯竭有关,这表明免疫疗法疗效降低.
在临床前模型中,AK7的过度表达增强了抗PD1治疗的有效性.

结论:

AK7作为cccRCC患者的潜在预后指标.
AK7调节,特别是其过度表达与抗PD1疗法相结合,显示出作为ccRCC的新治疗策略的前景.

Inhibition of Cdk Activity

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
