Tip60 Regulation Of Δnp63Α Is Associated With Cisplatin Resistance, Akshay Hira, Andrew Stacy, Jin Zhang, Michael P. Craig, Madhavi Kadakia
Symposium of Student Research, Scholarship, and Creative Activities Materials
About 5.4 million basal and squamous cell skin cancers are diagnosed every year in the US. ΔNp63a, a member of the p53 transcription factor family, is overexpressed in non-melanoma skin cancer and regulates cell survival, migration and invasion. TIP60 is histone acetyltransferase (HAT) which mediates cellular processes such as transcription and the DNA damage response (DDR). Previous studies in our lab have shown that overexpression of TIP60 induces ΔNp63a protein stabilization in a catalytic-dependent manner. Since ΔNp63a is known to transcriptionally regulate several DDR genes and promote cisplatin resistance, its stabilization by TIP60 may contribute to the failure of platinum-based …
