Chromosome 9 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 9, one copy inherited from each parent, form one of the pairs. Chromosome 9 is made up of about 140 million DNA building blocks (base pairs) and represents approximately 4.5 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 9 likely contains between 800 and 1,300 genes.

Genes on chromosome 9 are among the estimated 20,000 to 25,000 total genes in the human genome.

Short telomeres could be independent risk factor for age-related functional decline

Elderly people with short chromosome caps, or telomeres, are more likely to have difficulty performing daily activities such as carrying groceries, climbing stairs and walking, finds a new study of more than 1,200 people from five European countries.

Novel method using big data tools shows promising routes for research

A group of researchers affiliated to the University of São Paulo - campus Ribeirão Preto, Brazil, used big data tools such as data mining and network analysis to develop a method to help scientists and companies identify technological routes, trends and partnerships in any knowledge area. For this purpose, it collected information from patent databases around the world.

Subcutaneous injection of new protein helps treat hemophilia more effectively

Patients with hemophilia bleed spontaneously or following trauma. The most common sites of bleeding are into joints, but bleeds can also happen into any tissue in the body including the muscles, brain, or eyes.

Study reveals how gene variant affects chronic pain outcomes after trauma

The gene FKBP5 is a critical regulator of the stress response and affects how we respond to environmental stimuli. Previous studies have shown that certain variants of this gene play a role in the development of neuropsychiatric disorders such as posttraumatic stress disorder, depression, suicide risk, and aggressive behavior.

Researchers uncover how RNA regulates genes during critical stage in embryonic brain development

Scientists at the Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago and colleagues discovered how a type of RNA, called Evf2 enhancer RNA, regulates key genes during a critical stage in embryonic brain development.

Study shows that rogue proteins may underlie some ALS and frontotemporal dementia cases

ALS -- amyotrophic lateral sclerosis -- is a neurodegenerative disease that attacks motor neurons in the brain and spinal cord, slowly robbing its victims of their ability to walk, talk, breathe and swallow.

Scientists identify pathways that reveal insights into mechanism of lung cancer etiology

Lung cancer is the leading cause of preventable cancer death. A disease of complex origin, lung cancer is usually considered to result from effects of smoking and from multiple genetic variants.

Scientists uncover key control mechanism of DNA replication

Researchers from Osaka University in Japan have uncovered a key control mechanism of DNA replication with potential implications for better understanding how cells maintain genetic information to prevent diseases or cancer.

Brown University researchers reveal key physical properties of 'giant' cancer cells

Polyploidal cancer cells--cells that have more than two copies of each chromosome--are much larger than most other cancer cells, are resistant to chemotherapy and radiation treatments and are associated with disease relapse.

Study finds false negatives in common tests used to determine ROS1 status in lung cancer

Drugs like crizotinib are used to treat patients with ROS1-positive lung cancer. But which patients are ROS1-positive? A University of Colorado Cancer Center study published in the Journal of Thoracic Oncology shows that common laboratory tests used to determine ROS1 status all have inherent limitations that can lead to false-negative results.
