Abstract

The RAF/mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) kinase (MEK)/ERK (RAF/MEK/ERK) signaling cascade serves a prominent role in hepatocellular carcinoma (HCC) proliferation. Sorafenib (BAY 43‑9006) is a potent multikinase inhibitor of RAF kinases and a few receptor tyrosine kinases. Additionally, sorafenib causes apoptosis in a number of human tumor cell lines such as leukemia cell lines. Sorafenib is the first targeted drug to prolong the overall survival of patients with advanced HCC. However, sorafenib activity is less favorable in certain cancers, including sarcomas and melanomas, due to patient insensitivity and drug resistance. In the present study, a novel bi‑aryl urea, N‑(3‑trifluoromethylphenyl)‑N'-(2-methyl-4-(6‑cyclopropanecarboxamido-pyrimidin-4-yl) oxyphenyl) urea (CBI‑5725), is shown to be a potential candidate for the treatment of liver cancer. In the present study, the in vitro activities of CBI‑5725 and sorafenib in PLC/PRF/5 HCC cells were examined and the corresponding in vivo antitumor activities in PLC/PRF/5 human tumor xenografts. An alamar blue assay confirmed that CBI‑5725 was more cytotoxic than sorafenib to PLC/PRF/5 cells, suggesting that CBI‑5725 inhibited tumo...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Cell Cycle Pathways

Cell cycle is a complex process regulated by several signal transduction pathways and enzymes. Here is the latest research on regulation of cell cycle and cell cycle pathways.

Cell Signaling by Tyrosine Kinases

Receptor tyrosine kinases (RTKs) are the high-affinity cell surface receptors for many polypeptide growth factors, cytokines, and hormones. RTKs have been shown not only to be key regulators of normal cellular processes but also to have a critical role in the development and progression of many types of cancer. Discover the latest research on cell signaling and RTK here.
