Cancer cells growing in a dish
Scientists have mapped out the genes that keep our cells alive, creating a long-awaited foothold for understanding how our genome works and which genes are crucial in disease like cancer. A team of Toronto researchers have switched off, one by one, almost 18,000 genes – 90% of the entire human genome – to find the genes that are essential for cell survival. The data revealed a “core” set of more than 1,500 essential genes. This lays the foundation for reaching the long-standing goal in biomedical research of pinpointing a role for every single gene in the genome.
By turning genes off in 5 different cancer cell lines, including brain, retinal, ovarian, and 2 kinds of colorectal cancer cells, the team uncovered that each tumour relies on a unique set of genes t...
