The full results of the gene expression array are being deposited in the GEO database. Biological replicate hepatic samples were used for select genes to confirm changes in expression by RT-qPCR and immunoblotting. 2.5. Quantitative real time PCR analysis Real-time PCR was performed using the ...
Full size image Stable hepatic ChREBP overexpression promotes HCC initiation and development To test its potential oncogenic function, ChREBP was specifically overexpressed in the liver of male C57BL6/J mice. Three weeks after adenoviral ChREBP delivery, mice displayed hepatic steatosis, that was ...
Full size image To establish whether the exposure to CD induces changes in gene expression, we performed the analysis of RNA in E15.5 testes. For the analysis we chose genes, which are essential for germ cell specification (Prdm1), maintaining the pluripotent state (Pou5f1), and Sertoli cel...
