Host signaling pathways play important roles in the replication of influenza virus, but their functional effects remain to be characterized at the molecular level. Here we identify two receptor tyrosine kinase inhibitors (RTKIs) of the tyrphostin class that exhibit robust

Mitochondria dynamics controls not only their morphology but also functions of mitochondria. Therefore, an imbalance of the dynamics eventually leads to mitochondria disruption and cell death. To identify specific regulators of mitochondria dynamics, we screened a bioactive chemical compound library

To proliferate, vascular smooth muscle cells first convert from a contractile to a synthetic phenotype. Earlier studies indicate that this process is supported by fibronectin and accelerated by platelet-derived growth factor (PDGF). Here, the mechanisms in this transition were further
