Microtubule stabilizing agents (MSAs) are some of the most widely used and effective therapies availablefor the treatment of solid tumors. However, their utility is compromised by innate and acquired drugresistance. The taccalonolides (taccas) are a mechanistically unique class of MSAs that circumventmultiple clinically relevant forms of drug resistance. Multiple potent taccas identified by our laboratorieshave effective antitumor activity in drug sensitive and resistant in vivo models but suffer from a narrowtherapeutic window.

The proposed research investigates novel molecular targets and processes that promise to minimize brain damage after cerebral ischemic stroke (CIS) and traumatic brain injury (TBI). Current therapeutic strategies to combat acute brain injuries have been largely unsuccessful. We discovered that the Ca2+ dependent phosphatase calcineurin (CN) can bind to PERK, a stress sensor in the endoplasmic reticulum (ER), increases its auto-phosphorylation and enhance a cellular process called the Unfolded Protein Response (UPR).
