NDRG1 gene is a member of the N-Myc downregulated gene family which belongs to the alpha/beta hydrolase superfamily. NDRG1 is a cytoplasmic protein involved in stress responses, hormone responses, cell growth, and differentiation. NDRG1 is necessary for p53-mediated caspase activation and apoptosis. Mutations in the NDRG1 gene are a cause of Charcot-Marie-Tooth disease type 4D, and expression of this gene may be a prognostic indicator for several types of cancer. NDRG1 is a stress-responsive protein involved in hormone responses, cell growth, and differentiation. It acts as a tumor suppressor in many cell types.

PDRG1, also known as C2orf126, belongs to the prefoldin subunit beta family. It is predominantly expressed in normal testis and exhibits reduced but detectable expression in other organs. PDRG1 may play a role in chaperone-mediated protein folding. PDRG1 is overexpressed in tumors relative to normal tissues. Its expression is upregulated in multiple malignancies including cancers of the colon, rectum, ovary, lung, stomach, breast and uterus when compared to their respective matched normal tissues. Thus PDRG1 is a high-value novel tumor marker that could play a role in cancer development and/or progression.

Cell adhesion molecules belonging to the Cadm family, and in particular Cadm3 (axonal) and its heterophilic binding partner Cadm4 (Schwann cell), mediate these interactions along the internode.over-expressing Cadm3 on the surface of DRG neuron axons results in an almost complete inability by Schwann cells to form myelin segments. Axons of superior cervical ganglion (SCG) neurons, which do not normally support the formation of myelin segments by Schwann cells, express higher levels of Cadm3 compared to DRG neurons.
