Visceral adiposity is strongly associated with metabolic disease risk, whereas subcutaneous adiposity is comparatively benign. However, their relative physiological importance in energy homeostasis remains unclear. Here, we show that after 24-h fasting, the subcutaneous adipose tissue of mice acquires key properties of visceral fat. During this fast-induced 'visceralization', upregulation of mi...
Retroviruses can induce hematopoietic disease via insertional mutagenesis of cancer genes and provide valuable molecular tags for cancer gene discovery. Here we show that insertional mutagenesis can also identify genes that promote the immortalization of hematopoietic cells, which normally have only limited self-renewal. Transduction of mouse bone marrow cells with replication-incompetent murin...
Long-term glucocorticoid (GC) treatment induces central fat accumulation and metabolic dysfunction. We demonstrate that microRNA-27b (miR-27b) plays a central role in the pathogenesis of GC-induced central fat accumulation. Overexpression of miR-27b had the same effects as dexamethasone (DEX) treatment on the inhibition of brown adipose differentiation and the energy expenditure of primary adip...
In a recent issue of Haematologica, Matsuo et al. pinpoint the pejorative effect of EVI1 overexpression in 18 acute myeloid leukemias (AML) with MLL rearrangements. However, EVI1 overexpression has also been reported in patients with translocations involving chromosome 3 and the EVI1 gene. Because of the poor prognosis associated to these anomalies, it is important to investigate them at an ear...
During muscle regeneration, the transcription factor Pax7 stimulates the differentiation of satellite cells (SCs) toward the muscle lineage but restricts adipogenesis. Here, we identify HDAC4 as a regulator of Pax7-dependent muscle regeneration. In HDAC4-deficient SCs, the expression of Pax7 and its target genes is reduced. We identify HDAC4-regulated Lix1 as a Pax7 target gene required for SC ...
