NFKBIA

Also found in: Acronyms.

NFKBIA

A gene on chromosome 14q132 that encodes an I-kappa-B protein that inhibits the multimeric NFKB complex by trapping it in the cytoplasm. Kinases IKBKA or IKBKB phosphorylate NFKBIA’s serine residues, marking them for destruction via the ubiquination pathway, allowing activation of the NFKB complex which, once activated, translocates to the nucleus, binds DNA and activates transcription.

To test our hypothesis, we conducted a case-control study to investigate the association of NFKB1 -94 ins/del ATTG polymorphism and NFKBIA -826C>T and -881A>G polymorphisms with the risk of lung cancer in a Chinese population.

Association of NFKB1 and NFKBIA polymorphisms with lung cancer risk: The association between NFKB1 and NFKBIA polymorphisms and lung cancer risk is shown in Table-I.

The combinations of NFKBIA -826C>T polymorphism and NFKBIA -881A>G polymorphism and their association with lung cancer risk is shown in Table-IV.

Analysis of NFKBIA -826C>T risk association by gender and smoking status: The association between NFKBIA -826C>T polymorphism and lung cancer risk according to sex and smoking status is shown in Table-VI..

Polymorphisms in NF-B pathway genes and their association with risk of lung cancer in the Chinese population

The defects on NFKBIA and EGFR have a similar effect on an important molecule called NF-kappa-B, a "transcription factor" found in all cells, but they do this by different mechanisms.

In our study, UFPs altered the expression of many of the genes in these processes, including FOS (1.6-fold), JUN (1.3-fold), NFKBIA (1.3-fold), and early growth response-1 (EGR-1, Unigene accession no.
