Analysis of TSC1 mutation spectrum in mucosal melanoma.

ABSTRACT:

Purpose

Mucosal melanoma is a relatively rare subtype of melanoma for which no clearly established therapeutic strategy exists. The genes of the mTOR signalling pathway have drawn great attention as key targets for cancer treatment, including melanoma. In this study, we aimed to investigate the mutation status of the upstream mTOR regulator TSC1 and evaluated its correlation with the clinicopathological features of mucosal melanoma.

Methods

We collected 91 mucosal melanoma samples for detecting TSC1 mutations. All the coding exons of TSC1 were amplified by PCR and subjected to Sanger sequencing. Expression level of TSC1 encoding protein (hamartin) was detected by immunohistochemistry. The activation of mTOR pathway was determined by evaluating the phosphorylation status of S
