Project description:Expression analysis of human melanoma short-term culture WM451-Lu harvested after lentiviral infection with a GFP (control) or SETDB1 (experimental) viral vector
Project description:Investigation of expression differences induced by expression of the histone methyltransferase SETDB1 in human melanoma short-term culture WM451-Lu. A six-chip study using total RNA prepared from WM451-Lu melanoma short-term cultures infected with either a lentivirus encoding GFP (control) or SETDB1. Cells were allowed to grow for 2 days post-infection.

Project description:Histone modifications play a crucial role in the progression of various cancers. The histone methyltransferase SETDB1 catalyzes the addition of methyl groups to histone H3 at lysine 9. Here, we describe SETDB1 contribution to melanoma tumorigenesis. SETDB1 is highly amplified in melanoma cells and in patients’ tumors. Increased SETDB1 expression, which correlates with SETDB1 amplification, is associated with a more aggressive phenotype in in vitro and in vivo studies. SETDB1 implements its effects through the regulation of Thrombospondin 1. SETDB1’s SET-domain is essential to maintain its tumorigenic effects. SETDB1 inhibition reduces cell growth in melanomas resistant to targeted treatments. In essence, we support SETDB1 as a major driver of melanoma development, highlighting a role as potential future target for the treatment of this disease.
Project description:The aim of this work is to establish the impact of SETDB1 expression in melanoma. SETDB1 was overexpressed in melanoma cell lines (SETDB1 OE) and whole-genome expression profiles were compared to the control ( melanoma cells carrying an empty vector). .
