Transcriptomic analysis of melanoma cells reveals an association of α-synuclein with regulation of the inflammatory response.

ABSTRACT: The Parkinson's disease protein, alpha-synuclein (α-syn/SNCA), is highly expressed in neurons and melanomas. The goal of this study was to reveal the mechanism(s) of α-syn's involvement in melanoma pathogenesis. To decipher the genes and pathways affected by α-syn, we conducted an RNA sequencing analysis of human SK-MEL-28 cells and several SK-MEL-28 SNCA-KO clones. We identified 1098 significantly up-regulated genes and 660 significantly down-regulated genes. Several of the upregulated genes are related to the immune system, i.e., the inflammatory response and the matrisome. We validated five upregulated genes (IL-1β, SAA1, IGFBP5, CXCL8, and CXCL10) by RT-qPCR and detected IGFBP5 and IL-1β in spent media of control and SNCA-KO cells. The levels of each of these secreted proteins were sig
