A peroxisome proliferator-activated receptor (PPAR) binding site was identified in the murine FATP1 promoter. Several reports have shown a positive regulation of mouse FATPs by ligands that activate PPAR-a, PPAR-y, or PPAR-y/RXR heterodimers. 

NFAT proteins are expressed in skeletal, cardiac, and smooth muscle and play important roles in the regulation of the development and differentiation of these tissues. In skeletal muscle, NFAT isoforms are expressed at different stages of development and regulate progression from early muscle cell precursors to mature myocytes. NFAT proteins have also been shown to control the expression of the myosin heavy chain and positively regulate muscle growth [1, 2]. 

The majority of GPCRs couple to three families of G protein alpha subunits which differ in their ability to activate three distinct primary signaling cascades. The stimulatory G-protein Gas, positively regulates the activity of adenylyl cyclase causing an increase of intracellular cAMP levels as second messenger. In...

Positive regulators (enhancers) Turn on transcription when a specific effector protein binds to a specific enhancer sequence in the DNA. 

The a3 isoform is expressed mainly in adult neurons and neonatal cardiomyocytes. The a3 gene exhibits three positively regulating cis elements that bind NP-Y, Spl and Sp2 [10]. Its neuron specificity appears to be related to a neural-restrictive silencer element and a positively acting cis element [11]. 

Figure 1 The MAPK pathway and its connections to other signals A negative feedback loop connects the phosphorylated endpoint of the pathway ERK (Extracellular-signal Regulated Kinase) to the transcriptionally-driven synthesis of the phosphatase, MKP MAP kinase phosphatase. MKP then de-phosphorylates ERK to shut down the signaling cascade. The positive feedback loop again starts with the terminal kinase ERK which activates cPLA2 (cytosolic phospholipase A2). This leads to the synthesis of arachidonic acid, which, in turn activates protein kinase C (PKC). PKC is a positive regulator of RAS (Please see Color Plate Section in the back of this book).
