Rather, searching for a link between the expression of DAP3 and the mitochondrial biogenesis, we show that, when thyroid tumours have a rich mitochondrial content, whether they belong to the oxyphilic tumour categories, to the papillary carcinomas or UMP type, DAP3 overexpression is dependent on the cell mitochondrial content (Figure 3). Here, DAP3 is linked to neoplasm.
