Chromosome 8 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 8, one copy inherited from each parent, form one of the pairs. Chromosome 8 spans about 146 million DNA building blocks (base pairs) and represents between 4.5 percent and 5 percent of the total DNA in cells.

Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 8 likely contains between 700 and 1,100 genes.

Genes on chromosome 8 are among the estimated 20,000 to 25,000 total genes in the human genome.

Study links masculine norms to poor cardiovascular health awareness

Cardiovascular disease remains a top cause of sickness and death in the U.S. and worldwide. Doctors and researchers have it especially high on their radar because it's more modifiable and preventable than many other diseases and causes of death.

New study links pulmonary carcinoid aggressiveness to TERT gene activation

Pulmonary carcinoids are rare tumors of the lung with extremely different clinical courses. In many patients, they behave like benign tumors; surgical removal of the tumor leads to a complete cure. However, some patients experience aggressive growth and spread (metastasis) of the tumor with poor chances of recovery. The biological causes of these different forms of the disease are still unknown.
