Project description:MicroRNAs (miRNAs, miRs) are small noncoding RNAs, which control or are controlled by the dysregulation of multiple protein-coding oncogenes or tumor suppressor genes, play important roles in carcinogenesis. Myxoid liposarcomas (MLS) are characterized by t(12;16)(q13;p11) translocation and expression of TLS/CHOP chimeric transcripts (various types) which encode different oncogenic proteins. TLS-CHOP is important for the molecular mechanisms in the development of MLS, but the involvement in microRNA expression still remain poorly understood. Thus we explored the target microRNA of TLS-CHOP influence cell-proliferation or cell death with microarray.

TLS-CHOP is important for the molecular mechanisms in the development of MLS, but the involvement in microRNA expression still remain poorly understood. In this study, we have found that miR-486-5p (miR-486) expression level was downregulated by ectopic expression of TLS-CHOP fusion gene in mouse fibroblast cells (NIH3T3). In addition, we found overexpression of miR-486 inhibited the cell growth in the 2645/94 cells and in situ hybridization of miR-486 showed MLS tissues had lower signal intensity compared with non-tumor tissues. Thus we explored the target genes of miR-486 influence cell-proliferation or cell death with microarray. We compared the microRNA profiles of cells treated with TLS-CHOP or empty vector about NIH-3T3 cell-line. We compared the whole mRNA profiles of cells transfected with miR-486 oligonucleotides or control oligo about myxoid liposarcoma cell-line.

Project description:The TLS-CHOP fusion protein is found in the majority of human myxoid liposarcomas (MLS), and is thought to have oncogenic functions. Until now, however, the molecular function of TLS-CHOP for oncogenesis is still elusive. In this report, we have revealed that knockdown of TLS-CHOP by specific siRNA in MLS-derived cell lines inhibits cell growth and leads to cell death. Thus, TLS-CHOP may be a promising therapeutic target for MLS treatment. Thus we explored the target genes of TLS-CHOP influence cell-proliferation or cell death with microarray. We compared the whole mRNA profiles of cells treated with TLS-CHOP siRNA or control oligo in two myxoid liposarcoma cell-line.

Project description:We identified novel protein-protein interactions between FUS-CHOP, a fusion oncoprotein that drives myxoid liposarcoma, and SNF2H, the ATPase subunit of the imitation switch (ISWI) chromatin remodeling complex. We used antibodies for FUS-CHOP, SNF2H, and H3K27ac to profile localization of these proteins and histones marks on chromatin in human MLPS cell lines and show that colocalization of FUS-CHOP and SNF2H occurs at new enhancers marked by H3K27ac.
