Gene responsible for lung cancer identified!

We all know very well that lung cancer is one among the most important global health issue. Now no need to worry about this cancer as the scientists have found something that is responsible for the lung cancer. Scientists at the Genome Institute of Singapore have identified a gene responsible for lung cancer.
  
Cancer stem cells or tumor-initiating cells, in short "ITC" are responsible for tumor growth reported by Xinhua quoting the researchers. The scientists found a marker to identify these cells known as "CD166". The research team, lead by Bing Lim, associate director of cancer stem cell biology at the Genome Institute of Singapore, & Elaine Lim, medical oncologist affliated with Tan Tock Seng Hospital & National Cancer Centre Singapore, discovered several genes that were important for the growth of cancer cells.

The researchers discovered that in abnormal instances when the level of a metabolic enzyme known as glycine decarboxylase rises significantly, it causes changes in the behavior of the cell, making it cancerous. The glycine decarboxylase is a normal occuring enzyme in cells , present in small quantities. The finding reported in the online issue of Cell Jan 5, is believed to be huge step towards finding a cure for the disease.
