Abstract
Investigation of gene expression is a developing area with several methods available.
One method is quantitative PCR. A major pitfall in quantitative PCR is the normalisation
procedure of the gene expression. Many experiments include a housekeeping gene,
some use RNA concentration, and others use a geometric mean of several internal,
stably expressed genes. This study demonstrates that real-time-PCR results differ
with varying housekeeping genes and analysis protocols when applied to insulin-secreting
INS-1E cells derived from the pancreas and stimulated by DEDTC (diethyldithiocarbamate,
a zinc chelator) and GLP-1.
Key words
DEDTC - GLP-1 - UBC-7 - HPRT - cyclophilin A - ZnT-3 - ZnT-8
