Abstract: Provided herein are compounds and methods for use in preventing or treating a viral infection mediated by a virus comprising an IRES-containing RNA molecule or cancer related to an increase or decrease in IRES-mediated translation of an RNA molecule. Also provided are methods of inhibiting or promoting IRES-mediated translation. Also provided are methods of screening for an agent that inhibits IRES-mediated translation.

Abstract: Provided herein are methods of screening for an agent that is a PTH agonist or antagonist. For example, provided is a method of screening for an agent that is a PTH agonist or antagonist, the method comprising contacting a cell with LRP6 and the agent to be screened, wherein the cell comprises a PTH1R, and determining the level of LRP6 binding to the PTH1R. An increased level of LRP6 binding to the PTH1R compared to a control indicates the agent is a PTH agonist. A decreased level of LRP6 binding to the PTH1R compared to a control indicates the agent is a PTH antagonist. Also provided are methods of treating a skeletal disorder in a subject, wherein the skeletal disorder is characterized by proliferative bone growth or reduced bone density.
