Description
Staphylococcal nuclease domain-containing protein 1 (SND1) is overexpressed in human hepatocellular carcinoma (HCC) and positively regulates development and progression of HCC. We established stable clones expressing SND1 shRNA in QGY-7703 cells and analyzed the gene expression profiles of a control clone and two SND1 knockdown clones to check what genes are regulated by SND1.
Publication Title
Staphylococcal nuclease domain containing-1 (SND1) promotes migration and invasion via angiotensin II type 1 receptor (AT1R) and TGFβ signaling.

Description
Overexpression of LSF in less aggressive hepatocellular carcinoma (HCC) cells resulted in highly aggressive, angiogenic and multi-organ metastatic tumors while inhibition of LSF significantly abrogated growth and metastasis of highly aggressive HCC cells in nude mice.
Publication Title
Transcription factor Late SV40 Factor (LSF) functions as an oncogene in hepatocellular carcinoma.

Description
Astrocyte elevated gene-1 (AEG-1) as a positive inducer of hepatocellular carcinoma (HCC). Transgenic mice with hepatocyte-specific expression of AEG-1 were challenged with N-nitrosodiethylamine (DEN) and developed multinodular HCC with steatotic features. Thus, we have identified the follwoing AEG-1 functions: induction of steatosis, inhibition of senescence and activation of coagulation pathway to augment an aggressive hepatocarcinogenic phenotype.

Description
Macrophage activation is associated with profound transcriptional reprogramming. Although much progress has been made in the understanding of macrophage activation, polarization and function, the transcriptional programs regulating these processes remain poorly characterized. We stimulated human macrophages with diverse activation signals, acquiring a dataset of 299 macrophage transcriptomes. Analysis of this dataset revealed a spectrum of macrophage activation states extending the current M1 versus M2-polarization model. Network analyses identified central transcriptional regulators associated with all macrophage activation complemented by regulators related to stimulus-specific programs. Applying these transcriptional programs to human alveolar macrophages from smokers and patients with chronic obstructive pulmonary disease (COPD) revealed an unexpected loss of inflammatory signatures in COPD patients. Finally, by integrating murine data from the ImmGen project we propose a refined, activation-independent core signature for human and murine macrophages. This resource serves as a framework for future research into regulation of macrophage activation in health and disease.

Overall design: Since transcriptional programs are further modulated on several levels including miRNAs we assessed the global spectrum of miRNA expression by miRNA-Seq in macrophages stimulated with IFN?, IL4 or with the combination of TNFa, PGE2 and P3C
