Skin Ageing Signatures and Cancer (SASAC)

Identification of a Genomic/Transcriptomic Signature for Ageing and Predisposition to Skin Cancer in Normal Sun-exposed Skin

The aim of this study is to identify genetic patterns in normal ageing skin in order to better understand age-related changes.

Data has suggested that skin ageing has a genetic basis and past studies have identified genes that promote skin aging due to sun exposure.

Study Overview

• Status: Completed
• Conditions: Skin Cancer

Detailed Description

This study will use new tools in an attempt to understand the small changes that take place in skin and may be linked to skin ageing either due to age or the effect of the sun. Some data suggests that these changes may have a genetic basis.

In this study, the doctor will use a clinical scale to assess the participants skin type, the scale will range from 1-5 with 1 being fairer skin types and 5 being darker skin types. The doctors will select 10 female participants who meet the required skin types (1-4), aged between 55 and 65 years who attend clinics for reasons other than skin cancer or other skin diseases. 5 of these patients will have high levels of skin ageing and 5 will have low levels of skin ageing as defined by a set of pre-defined criteria. The criteria will be identified by examining the skin on the participants face and forearm. The study sponsor will collect skin and blood samples from all participants in the high and low skin ageing groups and these will be sent to a specialist laboratory for DNA and RNA analysis (genetic analysis).

The study sponsor hope that this will help us understand the effects of ageing on skin's normal functions but also help us interpret results coming out of other genetic studies in skin cancer. This information will help to better understand the changes linked with the development of skin cancer.

Study Population

Potential participants will be identified amongst patients attending outpatient clinics in dermatology, ophthalmology and other general medical specialities for reasons other than skin cancer or inflammatory skin disease. If required, volunteers will also be recruited by advertising from amongst staff within the hospital and Queen Mary University of London. Participants will be identified by the dermatology consultant or research fellow working on this study.

How is the study designed?

Number of groups / cohorts

1

Cohorts and Interventions

Group / Cohort
Arm; Registered participants will undergo a clinical assessment to determine whether they have high or low levels of skin ageing. The study will recruit 5 subjects with low levels of skin ageing and 5 subjects with high levels of skin ageing. Recruited patients will undergo skin punch biopsies, blood sampling and collection of lifestyle data.
