δ NP63α, the primary p63 isoform of the p53 transcription factor family, is a proto-oncogene implicated in non-melanoma skin cancers. Expressed in the basal layer of the epidermis, δ NP63α promotes cell survival and proliferation. Inhibition of this protein could potentially be beneficial in non-melanoma skin cancer patients. The first goal of this project was the purification of recombinant δ NP63α in Escherichia Coli. Recombinant δ NP63α was expressed as GST-δ NP63α followed by GST cleavage using GST trap affinity column chromatography yielding pure δ NP63α The second objective of this project was to test the binding capabilities of peptides …

Skin cancers, such as squamous cell carcinoma (SCC), develop from accumulated mutations as a result of excessive exposure to Ultraviolet B (UVB) radiation. Intriguingly, UVB also catalyzes the synthesis of 1alpha, 25-dihydroxy Vitamin D3 (VD3), the hormonally active form of Vitamin D. Downstream VD3 signaling has been associated with promoting the inhibition of cell cycle progression, regulating calcium homeostasis, and inducing differentiation and apoptosis. VD3 mediates these processes via genomic mechanisms through interaction with its cognate receptor, the Vitamin D Receptor, (VDR). In addition, it was recently discovered that VD3 reduces UVB-mediated phosphorylation of the SAPK/c-Jun N-terminal kinase (JNK), which …
