Chromosome 13 News and Research

RSS

Humans normally have 46 chromosomes in each cell, divided into 23 pairs. Two copies of chromosome 13, one copy inherited from each parent, form one of the pairs. Chromosome 13 is made up of about 114 million DNA building blocks (base pairs) and represents between 3.5 percent and 4 percent of the total DNA in cells.

Three-dimensional organization of genome plays key role in gene expression, cell fate

Scientists have long been reading the code of life - the genome -, as a sequence of letters but now researchers have also started exploring its three-dimensional organization.

FAU pre-medical student and surgeon work together on revolutionary procedure alternative to radical mastectomy

Elizabeth Hopkins, an aspiring physician and pre-medical student in the Charles E. Schmidt College of Science at Florida Atlantic University, has spent more than 640 hours shadowing Hilton Becker, M.D., a local plastic and reconstructive surgeon, and an affiliate professor in FAU's Charles E. Schmidt College of Medicine. Together, with Jeffrey Lind II, M.D., they authored a publication in the current issue of Plastic and Reconstructive Surgery Journal, which describes a revolutionary procedure developed by Becker that is an alternative to radical mastectomy.

Researchers analyze false-positive results from new prenatal genetic screens

Prenatal blood screening for extra or missing chromosomes in the fetus might give false-positive results if the mother's genome contains more than the usual number of certain DNA segments.

Study: Immune-regulating molecules can trigger lymphomas

A small group of immune-regulating molecules, when overproduced even moderately, can trigger the blood cancers known as lymphomas, according to a new study led by scientists from The Scripps Research Institute (TSRI).

Maryland researchers launch groundbreaking study into spread of drug-resistant malaria in Burma

University of Maryland School of Medicine researchers have launched groundbreaking research into the spread of potentially deadly drug-resistant malaria in the developing Southeast Asian nation of Myanmar, also known as Burma.

Researchers identify new gene variants linked with common childhood obesity

Genetics researchers have identified at least two new gene variants that increase the risk of common childhood obesity.

Drug resistance woes hamper anti-malaria fight

Researchers have found that there is increasing resistance to the front-line treatments for malaria. A pair of studies published in The Lancet and the journal Science showed how the disease is moving fast into new territory and identified a region of the parasite's genome that may be responsible for mutating in order to survive.

GWAS uncovers new genes associated with type 1 diabetes

The largest-ever analysis of genetic data related to type 1 diabetes has uncovered new genes associated with the common metabolic disease, which affects 200 million people worldwide. The findings add to knowledge of gene networks involved in the origin of this complex disorder, in which patients depend on frequent insulin injections to control their blood sugar levels.

Researchers reveal new gene associated with osteoarthritis

Researchers have today revealed a new gene associated with osteoarthritis. This is only the third gene to be identified for this painful and debilitating disease that affects more than 40 per cent of people aged more than 70 years.

New mechanisms of resistance to chemotherapy among leukemia patients

The interplay between a major tumor-suppressing gene, a truncated chromosome and two sets of microRNAs provides a molecular basis for explaining the less aggressive form of chronic lymphocytic leukemia, an international team of researchers reports today in the Jan. 4 edition of the Journal of the American Medical Association.

Biomarkers may help predict children at high risk of developing type 2 diabetes

Children who have a high risk of developing type 2 diabetes might be identified earlier by way of tell-tale genetic indicators known as biomarkers. Some of those new biomarkers might be pinpointed in research led by Nancy F. Butte and funded by the U.S. Department of Agriculture (USDA) and the U.S. Department of Health and Human Service's National Institutes of Health.

Researchers identify region of DNA that may contain gene linked to progression, spread of bowel cancer

Scientists have identified a region of DNA that appears to be involved in the development of pre-cancerous bowel growths (polyps) and that may contain a gene involved in the progression of bowel cancer.

Facial and brain anomalies in holoprosencephaly related chromosome aberrations characterized

Researchers at Signature Genomic Laboratories, which performs diagnostic genetic testing of chromosome abnormalities in individuals with unexplained physical and developmental disabilities, recently characterized a broad spectrum of facial and brain anomalies in individuals with chromosome aberrations associated with holoprosencephaly.

Wisconsin researchers identify the genetic region responsible for cardiovascular collapse during anesthesia

Researchers at The Medical College of Wisconsin in Milwaukee have identified the genetic region in rats responsible for cardiovascular collapse during anesthesia. While it is well known that people have different cardiovascular sensitivity to anesthesia causing some to collapse even when low doses are administered, the mechanism responsible for this susceptibility is not clear.
