TIMP-1 Promotes the Immune Response in Influenza-Induced Acute Lung Injury.

Introduction: Influenza infects millions of people each year causing respiratory distress and death in severe cases. On average, 200,000 people annually are hospitalized in the United States for influenza related complications. Tissue inhibitor of metalloproteinase-1 (TIMP-1), a secreted protein that inhibits MMPs, has been found to be involved in lung inflammation.

Cyclin E1 and RTK/RAS signaling drive CDK inhibitor resistance via activation of E2F and ETS.

High-grade serous ovarian cancers (HGSOC) are genomically complex, heterogeneous cancers with a high mortality rate, due to acquired chemoresistance and lack of targeted therapy options. Cyclin-dependent kinase inhibitors (CDKi) target the retinoblastoma (RB) signaling network, and have been successfully incorporated into treatment regimens for breast and other cancers. Here, we have compared mechanisms of response and resistance to three CDKi that target either CDK4/6 or CDK2 and abrogate E2F target gene expression.
