概括

血清蛋白激酶C三角酶 (PKCδ) 显示为检测肝细胞癌 (HCC) 的新生物标志物具有前途. 它可以识别早期和常规标记-负的HCC,提供新的诊断工具.

科学领域:

肝细胞癌 (HCC) 研究研究
在瘤学中发现生物标志物
胃肠病学和肝病学胃肠学和肝病学

背景情况:

肝细胞癌 (HCC) 是一种流行癌症,预后不佳.
早期检测HCC是具有挑战性的,特别是对于常规标志物负的病例.
需要替代生物标志物来识别早期的HCC.

研究的目的:

评估血清蛋白激酶C三角酶 (PKCδ) 作为一种用于检测HCC的新生物标志物.
评估PKCδ在患有慢性肝病 (CLD) 的患者的诊断性能.
为了比较PKCδ对已确定的HCC标志物如AFP和DCP的疗效.

主要方法:

分析了来自313名CLD患者的血清样本 (187名患有HCC,126名没有).
与三明治酶相关的免疫吸收试验 (ELISA) 用于测量血清PKCδ水平.
用ROC曲线分析评估诊断性能,并与AFP和DCP进行比较.

主要成果:

与非HCC CLD患者相比,HCC患者的血清PKCδ水平显著升高.
PKCδ在检测HCC方面表现出高灵敏度和特异性.
在PKCδ中,大约有40%的HCC病例呈AFP和DCP阴性,在检测小的早期瘤方面,其表现优于AFP/DCP.

结论:

血清PKCδ作为一种新的HCC生物标志物,独立于和补充传统标志物.
PKCδ显示了检测非常早期HCC的潜力.
这种生物标志物对于在AFP和DCP阴性患者中识别HCC特别有价值.

MAPK Signaling Cascades

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

PI3K/mTOR/AKT Signaling Pathway

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...
