Brief Summary:
This study aims to compare the expression of keratins before and after application of sulforaphane (SF) to determine whether this agent alters skin fragility seen in both intrinsic and extrinsic skin aging and UV light exposure.

Condition or disease Intervention/treatment Phase
Aging Drug: Sulforaphane Radiation: Narrow-band Ultraviolet B exposure Procedure: 4 mm skin punch biopsy Phase 2

Detailed Description:

The primary purpose of the study is to compare the expression of keratins before and after application of sulforaphane (SF) and determine whether these findings alter skin fragility seen in both intrinsic and extrinsic skin aging as well as in ultraviolet (UV) light exposure.

This investigation will be done in collaboration with researchers from the Department of Biochemistry and Molecular Biology and Bloomberg School of Public Health at Johns Hopkins University. The study population recruited by Johns Hopkins Department of Dermatology will include up to 50 individuals over the age of 18 with healthy skin. Each study participant will have four on-site study visits and will be asked to contribute photographs, undergo non invasive elasticity measurements, use topical sulforaphane for 7 days and contribute up to four biopsy specimens for laboratory study. The investigators will also evaluate any differences in keratins' expression in skin exposed to acute UV light, separately and after pretreatment with sulforaphane.

Arm Intervention/treatment
Experimental: Group A
Sulforaphane will be applied topically to both sites for up to 7 consecutive nights. Biopsies will be obtained prior to, and immediately after this intervention, on standard photoprotected and photoexposed sites.
Drug: Sulforaphane
Isothiocyanate sulforaphane (SF), derived from broccoli sprouts, has been known to induce an antioxidant response through the Keap1-Nrf2-antioxidant response element pathway.
Other Name: Broccoli sprout extract; isothiocyanate sulforaphane

Procedure: 4 mm skin punch biopsy
All areas will be biopsied using standard punch biopsy tools and following standard clinical protocols, including cleansing the skin with an alcohol wipe and injecting local anesthesia with lidocaine and epinephrine. No more than four total skin biopsies will be obtained from a volunteer over the course of the study. After removal of the tissue sample, one or two sutures are placed to close the circular opening. Sutures are removed and a scar is formed, but typically heals well without complications and blends well with the surrounding skin.
Other Name: biopsy

Experimental: Group B
Two photoprotected sites will be identified. Sulforaphane will be applied topically to a single selected site for up to 7 consecutive nights. Both site will be exposed to UV. Biopsies of both sites will be obtained prior to, and 24 hours after UV exposure.
Drug: Sulforaphane
Isothiocyanate sulforaphane (SF), derived from broccoli sprouts, has been known to induce an antioxidant response through the Keap1-Nrf2-antioxidant response element pathway.
Other Name: Broccoli sprout extract; isothiocyanate sulforaphane

Radiation: Narrow-band Ultraviolet B exposure
The investigators will use a Lumera UVB light phototherapy device which allows for targeted delivery of controlled doses of UVB radiation (emission spectrum 290-320 nm).
Other Name: UVB, UV

Procedure: 4 mm skin punch biopsy
All areas will be biopsied using standard punch biopsy tools and following standard clinical protocols, including cleansing the skin with an alcohol wipe and injecting local anesthesia with lidocaine and epinephrine. No more than four total skin biopsies will be obtained from a volunteer over the course of the study. After removal of the tissue sample, one or two sutures are placed to close the circular opening. Sutures are removed and a scar is formed, but typically heals well without complications and blends well with the surrounding skin.
Other Name: biopsy




Primary Outcome Measures :
  1. Quantitative RT-PCR and Immunohistochemistry to assess Keratin 16 and 17 induction in the basal epidermis. [ Time Frame: Within 6 months after last patient recruited. ]
    We quantify the induction as measured by fold-change of keratin 16 and keratin 17 in the basal layer of the epidermis in both photoprotected and photodamaged skin treated with sulforaphane.


Secondary Outcome Measures :
  1. Quantitative RT-PCR and Immunohistochemistry to assess gene expression changes [ Time Frame: Within 6 months after last patient recruited. ]
    We will measure the fold-change in gene expression in human skin after acute UV light exposure, separately and in combination with application of topical sulforaphane.
