Yin Yang 1 (YY1) is a member of polycomb protein family involved in epigenetic modifications and transcriptional controls. We have shown that YY1 acts as positive regulator of tumor growth and angiogenesis by interfering with the VEGFA network. Yet, the link between polycomb chromatin complex and hypoxia regulation of VEGFA is still poorly understood. Here, we establish that hypoxia impairs YY1 binding...
Genome-wide association studies have revealed several genes predisposing to autoimmunity, however, concordance rates in monozygotic twins are significantly below 50% for several autoimmune diseases. The limited presence of a strong genetic association only in some patients supports that other non-genetic mechanisms are active in these pathologies. Epigenetic modifications such as DNA methylation,...
