Chromosome 4 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 4, one copy inherited from each parent, form one of the pairs. Chromosome 4 spans more than 191 million DNA building blocks (base pairs) and represents more than 6 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 4 likely contains between 1,300 and 1,600 genes.

Genes on chromosome 4 are among the estimated 20,000 to 25,000 total genes in the human genome.

Microarray analysis ‘best test for prenatal diagnosis’

Chromosomal microarray analysis is able to identify significantly more clinically relevant information for prenatal diagnosis than is karyotyping, and is equally able to highlight aneuploidies and unbalanced rearrangements, US study findings suggest.

Ibrutinib may effectively combat chronic lymphocytic leukemia

The promising investigational targeted therapy ibrutinib and its mechanism of silencing gene communication pathways critical to the development of cancer may be an effective way to combat chronic lymphocytic leukemia (CLL), according to studies presented today at the 54th Annual Meeting of the American Society of Hematology (ASH).

New prenatal genetic test results in more clinically relevant information

A large, multi-center clinical trial led by researchers from Columbia University Medical Center (CUMC) shows that a new genetic test resulted in significantly more clinically relevant information than the current standard method of prenatal testing.

Ponatinib offers new hope in drug-resistant leukemia

An investigational tyrosine kinase inhibitor, ponatinib, has shown high levels of activity in patients with chronic myeloid leukemia and Philadelphia chromosome-positive acute lymphoblastic leukemia.

Researchers discover four new gene regions that contribute to low birth weight

An international team of genetics researchers has discovered four new gene regions that contribute to low birth weight. Three of those regions influence adult metabolism, and appear to affect longer-term outcomes such as adult height, risk of type 2 diabetes and adult blood pressure.

NAP and SAL injection during pregnancy improve memory, learning tasks in offsprings

Mice with a condition that serves as a laboratory model for Down syndrome perform better on memory and learning tasks as adults if they were treated before birth with neuroprotective peptides, according to researchers at the National Institutes of Health.

Clinical trial shows effectiveness of ponatinib in patients with leukemia and lymphoma

Huntsman Cancer Institute researchers Michael Deininger, M.D., Ph.D., and Thomas O'Hare, Ph.D., were part of a team that found a potent oral drug, ponatinib, effective in patients who have developed resistance to standard treatments for chronic myeloid leukemia and Philadelphia chromosome positive acute lymphoblastic lymphoma.

Novartis to highlight key data from extensive oncology portfolio at SABCS and ASH meeting

Novartis will highlight more than 140 presentations on key data from its extensive oncology portfolio at the leading year-end scientific meetings devoted to hematology and breast cancer, demonstrating continued innovation in research and development efforts to advance the care of patients with cancer and rare diseases.

Ponatinib thwarts T315I gene mutation in chronic myeloid leukemia

A previously invincible mutation in chronic myeloid leukemia (CML) has been thwarted by an investigational drug in a phase I clinical trial reported in the current edition of The New England Journal of Medicine.

Combination of blood test and whole-genome sequencing technology could screen cancers

Scientists at the Johns Hopkins Kimmel Cancer Center have combined the ability to detect cancer DNA in the blood with genome sequencing technology in a test that could be used to screen for cancers, monitor cancer patients for recurrence and find residual cancer left after surgery.

Study broadens understanding of how cells regulate X chromosome inactivation

In a paper published in the Nov. 21 issue of Cell, a team led by Mauro Calabrese, a postdoctoral fellow at the University of North Carolina in the lab of Terry Magnuson, chair of the department of genetics and member of the UNC Lineberger Comprehensive Cancer Center, broadens the understanding of how cells regulate silencing of the X chromosome in a process known as X-inactivation.

Gadd45g protein essential in initiating development of male sex organs

Scientists at the Institute of Molecular Biology (IMB) in Mainz have identified a protein essential for initiating the development of male sex organs. Loss of the gene Gadd45g results in complete sex reversal of male mice, making them appear female.

Glycoprotein gene flags up heart disease

The glycosylphosphotidylinositol-anchored membrane glycoprotein CD14 gene significantly predicts cardiovascular mortality in adults aged 65 years or over, research shows.

IL-13 receptor system could play a major role in Parkinson's

Deciphering what causes the brain cell degeneration of Parkinson's disease has remained a perplexing challenge for scientists. But a team led by scientists from The Scripps Research Institute (TSRI) has pinpointed a key factor controlling damage to brain cells in a mouse model of Parkinson's disease.

Researchers discover new gene for susceptibility to Alzheimer's disease

A large-scale international study involving French researchers from the Inserm-Institut Pasteur Lille-Universit- Lille Nord de France "Public health and molecular epidemiology of ageing-related diseases" joint research unit led by Philippe Amouyel, has just discovered a gene for susceptibility to a rare disease that causes susceptibility to a common one, Alzheimer's disease, providing evidence of the heterogeneous aetiology of Alzheimer's disease.
