Androgens Induce Sebaceous Differentiation in Sebocyte Cells Expressing a Stable Functional Androgen Receptor
Studysummary This study found that active androgens activate lipogenic differentiation in human sebocytes expressing a functional androgen receptor, influencing gene expression and lipid synthesis, while also increasing apoptotic cell population over time.

The study established a stable human sebocyte cell line expressing a functional androgen receptor (AR) to investigate the effects of androgens on sebocyte differentiation. Treatment with dihydrotestosterone (DHT) in these cells modulated androgen-sensitive genes, decreased stem cell and hair markers, and increased sebocyte markers. DHT also induced lipid synthesis, increased cell size, and led to apoptosis over 7 days. These findings demonstrated that active androgens alone could drive immature sebocytes into a clear lipogenic differentiation process, highlighting the importance of AR in sebaceous function and providing a model for pharmacological testing.
