Three paths to melanoma
The evolution to melanoma depends on the order in which pathogenic mutations accumulate.

Pathways disrupted
Signaling pathways become disrupted in a stereotypical fashion during the progression of cutaneous melanoma.

Evolution of uveal melanoma
The metastatic progression of melanomas originating in the eye.

Genes involved in melanoma
A curated list of genes with pathogenic mutation in melanoma.

Genes under selection in cSCC
A curated list of genes with pathogenic mutations in cSCC.

Visualizing somatic mutations in skin cancer
Somatic mutations are detectable in spatial transcriptomic data. Here, we mark spots with somatic point mutations in a cutaneous squamous cell carcinoma biopsy.

The Shain laboratory is located in the Department of Dermatology at the University of California San Francisco. We are always hiring at all levels of training. Please contact Hunter Shain to express interest or for more details ([email protected]).

For the latest news on the Shain laboratory, follow along on Twitter.

The overarching goal of the Shain laboratory is to better understand the biology of skin cancer. We use a variety of -omic approaches to delineate the genetic and transcriptomic alterations in melanocytes, keratinocytes, melanomas, and keratinocyte cancers. Recently, we have initiated single-cell based studies (both DNA- and RNA- single-cell sequencing) as well as spatial transcriptomic studies. For more details related to ongoing projects, please reach out to the PI (Hunter Shain at [email protected]).
