Non-melanoma Skin Cancer
Conditions
Brief summary
To assess the effect of orally administered grape powder on the sunburn reaction in humans.
Detailed description
To determine whether oral grape powder will result in a reduction in biomarkers associated with basal cell carcinomas (BCCs) and squamous cell carcinomas (SCCs). Biomarkers taken from non-sun-exposed skin and UV-exposed skin before and after treatment will be compared. The ultimate goal of this study will be to generate new knowledge of the photoprotective effect of grape powder on UV exposure. The results may be employed as the basis for a larger clinical trial to evaluate the potential of grapes to prevent non-melanoma skin cancers (NMSCs) and sun damage.
Interventions
OTHERReconstituted grape powder
To prevent UV-induced skin cancers. Each subject's will have one arm exposed to 6 separate doses of UV (J/m2) \[114, 217, 343, 500, 619, 848\].

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of subjects reporting protective effect against sunburn response to UVG and/or UVA1 following administration of dietary grape powder. | 2 weeks | Assessment will be quantified by evaluation of a person's minimal erythema dose (MED), the smallest amount of ultraviolet (UV) required to achieve a sunburn response. 6 small areas of skin (2 inches by 2 inches) on the inner part of a person's arm will be exposed to 6 separate but increasing doses of UV. 24 hours after UV treatment, the area that received the smallest dose of UV and has a visible area of redness will be marked and the respective UV dose will be considered the MED. A desirable outcome would be if an individual's MED goes up after 2 weeks of grape treatment. |

| Measure whether dietary grape powder results in a significant (p<0.05 using parire ttest) % change in markers associated with NMSC as measured by it biomarker: proliferating cell nuclear antigen (PCNA) | 2 weeks | Immunohistochemistry (IHC) will be used to quantify the percentage of stained cells using the microscope.
