Bioactive small molecules facilitate numerous types of Life Science research approaches (enzyme substrates, activators and inhibitors, cell signaling modulator, cell culture…). Accessing reasonably priced, well-characterized molecules without jeopardizing quality and purety is sometimes quite challenging.
The transition from non-invasive phenotype to invasive phenotype of tumor cells marks the switch from a benign tumor to a more malignant form of cancer. Understanding the mechanisms underlying this hallmark event, which enables tumor cells to invade through Extracellular matrix, is critical for discovering pathways and new targets to develop anti-metastatic strategies. The discovery of anti-metastatic agents that inhibit cancer cell motility has been hindered by a dearth of cell motility assays that are compatible with high–throughput screening. [Read more…]
They regulate gene expression by interfering with the chromatin structure and the binding of effector proteins to post-translational modified histones (1).
Several experimental strategies to analyze such binding have recently been designed; histone modified peptide arrays being one of them. [Read more…]
