The Human Retinoic Acid Pathway RT² Profiler PCR Array profiles the expression of 84 key genes involved in retinoic acid signaling. Retinoic acid (RA) is the primary functional derivative of vitamin A (retinol) and its activity is implicated in many aspects of vertebrate development and homeostasis, while disruptions in this pathway cause developmental abnormalities and disrupt function in adipose, cardiac, nervous, reproductive, and integumentary tissues, among others. RA acts primarily by binding a family of nuclear receptors (the retinoic acid receptors alpha, beta, and gamma) that then heterodimerize with their partners (the retinoid X receptors alpha, beta, and gamma) and alter transcription. Additionally, recent evidence suggests that an alternative receptor (PPAR delta) also responds to RA signaling in some tissues and that retinol, and RA may also induce non-genomic cellular effects. Thus, the effect of RA depends on the expression of its cognate receptors, enzymes responsible for converting retinol to RA, metabolic enzymes that reduce RA levels, and transport proteins, some of which act as signal transducers that appear to influence the distribution of RA and its metabolic precursors. This array includes genes encoding the known receptors and proteins responsible for synthesis, transport and metabolism of RA and its precursors, as well as downstream targets of RA signaling. Results obtained with this array can yield insights into RA signaling mechanisms and responses. A set of controls present on each array enables data analysis using the ΔΔCT method of relative quantification and assessment of reverse transcription performance, genomic DNA contamination, and PCR performance. Using real-time PCR, research studies can easily and reliably analyze the expression of a focused panel of genes involved in retinoic acid signaling with this array.
