No.Gene symbolFull nameFunction

1CDKN2ACyclin-dependent kinase inhibitor 2ACapable of inducing cell cycle arrest in G1 and G2 phases. Acts as a tumor suppressor. Acts as a negative regulator of the proliferation of normal cells by interacting strongly with CDK4 and CDK6
2IGF1RInsulin-like growth factor 1 receptorThe activated IGF1R is involved in cell growth and survival control. IGF1R is crucial for tumor transformation and survival of malignant cell
3MDM2MDM2 proto-oncogeneInhibits p53/TP53- and p73/TP73-mediated cell cycle arrest and apoptosis by binding its transcriptional activation domain. Inhibits DAXX-mediated apoptosis by inducing its ubiquitination and degradation
4SMAD3SMAD family member 3Receptor-regulated SMAD (R-SMAD) that is an intracellular signal transducer and transcriptional modulator activated by TGF-beta (transforming growth factor) and activin type 1 receptor kinases
5SLC2A1Solute carrier family 2 member 1Facilitative glucose transporter. This isoform may be responsible for constitutive or basal glucose uptake, has a very broad substrate specificity, and can transport a wide range of aldoses including both pentoses and hexoses
6GRM5Glutamate metabotropic receptor 5Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors
7PLCB4Phospholipase C beta 4The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes
8FGFR1Fibroblast growth factor receptor 1Tyrosine-protein kinase that acts as cell-surface receptor for fibroblast growth factors and plays an essential role in the regulation of embryonic development, cell proliferation, differentiation, and migration
9UBE2V2Ubiquitin conjugating enzyme E2 V2Plays a role in the control of progress through the cell cycle and differentiation, plays a role in the error-free DNA repair pathway, and contributes to the survival of cells after DNA damage
10TNFRSF10BTNF receptor superfamily member 10bPromotes the activation of NF-kappa-B. Essential for ER stress-induced apoptosis
