Meredith Shiels, PhD, MHS and Anil Chaturvedi, PhD, of the National Cancer Institute in Rockville, MD, and their colleagues analyzed 1,429 variants in inflammation- and immunity-related genes from 378 patients with lung cancer and 450 healthy controls from the Prostate, Lung, Colorectal and Ovarian (PLCO) cancer screening trial.
The investigators observed a significant link between lung cancer and 81 single nucleotide polymorphisms (SNPs) located in 44 genes.
They then compared these results with observed or imputed data from four recently completed genome-wide association studies (GWAS) that included 5,739 lung cancer cases and 5,848 controls. Of the 81 SNPs, one in particular—named rs4648127 and located within the NFKB1 gene—was associated with lung cancer in both analyses.
This SNP was linked with an estimated 44 percent reduced risk of lung cancer in the cancer screening trial and a 21 percent reduced risk in the combined GWAS analysis.
The NF-êB, or nuclear factor kappa B, protein that is produced in part from the NFKB1 gene is known to play an important role in immunity and inflammation by regulating gene expression, cell death, and cell proliferation. Also, previous research has shown that immunity and inflammation may affect the development of lung cancer.
"Our study provides further evidence that inflammation may be associated with lung cancer risk," said Dr. Shiels. She added that future studies should further examine the NFKB1 gene and its relationship with lung cancer risk.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
