Abstract

Melanoma remains to be one of the most incurable cancers. Discovery of novel antitumor agent for melanoma therapy is expected. We recently isolated Oxyfadichalcone C from Oxytropis falcate and investigated the anti-proliferative and anti-metastatic activity on human melanoma A375 cells in vitro. Cell viability was determined using MTT assay and soft agar cloning formation assay. The effect of Oxyfadichalcone C on cell cycle distribution and apoptosis were analyzed by flow cytometry. Cell metastasis was determined by wound healing assay, Transwell assay and Gelatin zymography assay. The effect of Oxyfadichalcone C on signal proteins of PI3K/Akt and MAPK/ERK pathways was examined by western blot analysis. Synergism assay was employed to determine whether combination of Oxyfadichalcone C with Vemurafenib would enhance the anti-proliferative effect. Oxyfadichalcone C potently inhibited proliferation, induced G1 phase arrest and weak apoptosis in A375 cells. Anti-migration and anti-invasion activities were also indicated. Such effects were associated with upregulation of p27, reduction of cyclin D1, p-pRb, p-Integrin β1, as well as the proteolytic activity of metalloproteinase (MMP)-2/9. Meanwhile, key molecules of PI3K/Akt and MAPK...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 Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.

AKT Pathway

This feed focuses on the AKT serine/threonine kinase, which is an important signaling pathway involved in processes such as glucose metabolism and cell survival.

Cell Cycle Control & Proteolysis

Key regulators of cell cycle, including cyclins, cyclin dependent kinase inhibitors, DNA replication factors, are controlled by proteolysis. Discover the latest research on cell cycle control and proteolysis.

Cell Migration in Cancer and Metastasis
