| Title |
Differential expression analysis of RNA-seq data from melanocytes driven by tumor cell-derived exosomes |
| Organism |
Homo sapiens |
| Experiment type |
Expression profiling by high throughput sequencing

| Summary |
Exosomes (40–100 nm) are organelle-like membranous structures shed into interstitial spaces and body fluids under diverse pathophysiologic conditions, including tumor development. The tumor microenvironment is abundant with exosomes secreted by the cancer cells themselves. Studies have shown that tumor-derived exosomes can transport RNA and active molecules to other cells to promote tumor growth. Exosomes are increasingly being recognized as a major contributor in the progression of malignant neoplasms. We have found that normal melanocytes can acquire invasiveness through the internalization of melanoma cell-derived exosomes. However, little is known about how the exosomes modulate the melanocytes in the microenvironment to optimize conditions for tumor progression and metastasis. We hypothesize that melanoma cell-derived exosomes can drive the dysregulation of transcriptomes in normal melanocytes and facilitate melanoma progression. Our objective is to identify differentially expressed genes in melanocytes driven by tumor cell-derived exosomes through RNA sequencing and translate those genes as therapeutic targets for melanoma metastasis.

| Overall design |
Total RNA was extracted from three groups of human melanocytes: NHEM-c melanocytes without exosomes (control group), NHEM-c melanocytes co-cultured with A375 melanoma cell-derived exosomes, and NHEM-c melanocytes co-cultured with A549 lung cancer cellderived exosomes.
