Table 2. Tumor suppressor genes involved in NPC development.

Gene name Tumor-associated functions
ADAMTS9 (A disintegrin and metalloproteinase with thrombospondin motifs 9) Inhibits angiogenesis by reduction of MMP9 and vascular endothelial growth factorA (VEGFA) expression[96],[97]
ADAMTS18 (A disintegrin and metalloproteinase with thrombospondin motifs 18) Activates diverse cell surface molecules, inhibits both anchorage-dependent and -independent growth[98]
BLU/ZMYND10 (zinc finger, MYND-type containing 10) Involves inhibition of angiogenesis, transcription factor stress response, and tumor suppression[99][101]
BRD7 (bromodomain containing 7) Regulates transcription and causes cell cycle arrest[102]
CDH1 (Cadherin 1, type 1, E-cadherin) Inhibits proliferation, invasion, and metastasis[103]
CDKN2A/p16 (cyclin-dependent kinase inhibitor 2A) Inhibits CDK4 kinase and causes cell cycle arrest[103]
CMTM3 (CKLF-like MARVEL transmembrane domain- containing 3) Involves cellular chemokine signaling[104]
CRIP2 (cysteine-rich intestine protein 2) Inhibits angiogenesis by transcriptional repression[105]
CRYAB (alpha B-crystallin) Suppresses tumorigenesis and epithelial-mesenchymal transition (EMT) by associating with adherens junction[106]
DLC1/ARHGAP7 (deleted in liver cancer 1) Involves cell cytoskeleton organization, activates GTPase, signal transduction, and cell adhesion, inhibits cell invasion[107]
DLEC1 (deleted in lung and esophageal cancer 1) Inhibits cell growth and invasiveness[108]
DUSP6 (dual specificity phosphatase 6) Suppresses cell proliferation, induces apoptosis, inhibits EMT by negatively regulating the activity of ERK[109]
FBLN2 (fibulin 2) Interacts with extracellular matrix (ECM) proteins; inhibits cell proliferation, migration, and invasion; suppresses angiogenesis[110]
FBLN3 (EGF-containing fibulin-like extracellular matrix protein 1) Suppresses migration and invasion of NPC cells and involves the regulation of Akt signaling pathways[111]
GADD45G (growth arrest and DNA damage-inducible, gamma) Involves DNA damage response, inhibits cell growth and colony formation[112]
IGFBP-6 (insulin-like growth for binding protein 6) Inhibits the proliferation, invasion, and metastasitic abilities; increases the apoptosis events of NPC cells; associates with the expression of EGR-1[113]
IRF8 (interferon regulatory factor 8) Affects host defense, cell growth, differentiation, immune regulation and inhibits clonogenicity[114]
LARS (leucyl-tRNA synthetase) Catalyzes ATP-dependent ligation of L-Leu to tRNA (leu) and is inactivated in NPC by both genetic and epigenetic mechanisms[115]
LTBP2 (latent transforming growth factor beta binding protein 2) Reduces focal adhesion and cell migration, suppresses angiogenesis[116]
MIPOL1 (mirror-image polydactyly 1) Arrests cell cycle transition[117]
MMP19 (matrix metallopeptidase 19) Breaks down ECM to affect cell proliferation, migration, and adhesion[118]
PCDH10 (protocadherin 10) Mediates cell-cell adhesion, induces apoptosis, and be involved in cell signaling[119]
PTPRG (protein tyrosine phosphatase receptor type G) Arrests cell cycle, involves cell-ECM interactions, dephosphorylates kinases[120]
RASSF1A [ras association (RalGDS/ AF-6) domain family 1] Involves cell cycle arrest, induces apoptosis, involves DNA repair, inhibits accumulation of cyclin D1[121]
THY1/CD90 (Thy-1 cell-surface antigen) Involves suppression of tumor formation, cell proliferation, and invasion[122],[123]
TSLC1/CADM1 (tumor suppressor in lung cancer 1/cell adhesion molecule 1) Inhibits cell growth and induces apoptosis[124],[125]
WIF1 (WNT inhibitory factor 1) Inhibits WNT proteins, involves protein-tyrosine kinase activity[126]
ZNF382 (KRAB zinc finger protein) Inhibits proliferation, induces apoptosis[127]
