GAPDH

A gene on chromosome 12p13 that encodes glyceraldehyde-3-phosphate dehydrogenase, which has both glyceraldehyde-3-phosphate dehydrogenase and nitrosylase activities. It catalyses the reversible
oxidative phosphorylation of glyceraldehyde-3-phosphate in the presence of inorganic phosphate and nicotinamide adenine dinucleotide, an important energy-yielding step in carbohydrate metabolism. GADPH participates in nuclear events, including transcription, RNA transport, DNA replication and apoptosis.

Glyceraldehyde-3-phosphate dehydrogenase mRNA levels might be regulated under common situations, and in some cases, gapdh could be inappropriate as a reference gene for some experimental conditions.

Expression levels were normalized with glyceraldehyde-3-phosphate dehydrogenase (GAPDH).
All samples were studied in triplicate and the mRNA abundance was normalized for each sample to the amount of glyceraldehyde-3-phosphate dehydrogenase (GAPDH).
The coenzyme reduces in the glyceraldehyde-3-phosphate dehydrogenase reaction, and the resulting NADH oxidizes in the LDH reaction at mean rate of 2-4 mmol per liter of packed RBCs per h (mmol/[l.sub.RBCs] x h).
The primers were designed by Primer Express [sup][R] v.2.0 software (Applied Biosystems, Foster City, CA, USA), using glyceraldehyde-3-phosphate dehydrogenase ( GAPDH ) as a housekeeping control gene.
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has been considered a classical cytosolic glycolytic protein and in some microorganisms plays some role in cell flocculation (8).
