I'm doing a RT-qPCR in murine heart samples and searching for best housekeeping genes. More specifically I'm interested in genes which expression in heart would not change during high fat diet or left ventricular hypertrophy.
I recommend you the database "Housekeeping and Reference Transcript Atlas" (www.housekeeping.unicamp.br) for heart tissue. It offers tissue/cell (102 human tissues and 22 mouse tissues at this moment) selective candidate reference transcripts for qPCR normalization. Interestingly, some validated ready to use primers are also available in this database. The database analyzes a large RNA-seq dataset to select the most stable transcripts for qPCR normalization.
