Since we have previously shown that HMGA1 is able to negatively regulate CBX7 expression (Mansueto et al., 2010) and that HMGA1 positively regulates miR-181 that has CBX7 as target, we can envisage a HMGA1-CBX7 network that operates in the regulation of tumour progression and adipocyte cell growth and differentiation. This evidence concerns the gene HMGA1 and neoplasm.
