OverallSystems Analysis of Epigenomic Architecture in Cancer ProgressionDespite anti-hormone therapies in patients, the cognate receptors ER? and AR can remain functional tosupport oncogenic signaling for advanced progression of breast and prostate cancers. Intensive studies haveuncovered cellular and biochemical changes underlying the development of hormone resistance. However,epigenetic mechanisms for establishing and maintaining a hormone-resistant phenotype remain to beexplored.

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.

Numerous studies have indicated that pain is the top ranked symptom in head and neck cancer (HNC)patients. However, available treatments are limited and associated with severe side effects addingsubstantially to the burden of having cancer. Thus, there is a critical need for novel analgesics.

The San Antonio Breast Cancer Symposium (SABCS) is a five day international symposium thatprovides state-of-the-art information on translational research in breast cancer both for basicscientists and clinicians who work directly with patients.

This competing renewal application requests a second five-year support by the Ruth Kirschstein NationalResearch Service Award (T32) for our ?Cancer Biology Training Program? based at the University of TexasHealth Science Center at San Antonio (UTHSCSA), a Hispanic-Serving Institution.
