Study identifies existence of an antitumor molecule that originates within SMYD3 oncogene

A common point in all human tumors is that they produce an activation of oncogenes, genes that cause cancer and they also cause a loss of function of the protective genes, called anti-oncogenes or tumour suppressor genes. Normally both categories of anticancer and procancer genes are in different regions of our chromosomes.

Novel assay accurately detects trisomy 21 or 18 from maternal blood samples

Current screening strategies for Down syndrome, caused by fetal trisomy 21 (T21), and Edwards syndrome, caused by fetal trisomy 18 (T18), have false positive rates of 2 to 3%, and false negative rates of 5% or higher. Positive screening results must be confirmed by amniocentesis or chorionic villus sampling, which carry a fetal loss rate of approximately 1 in 300 procedures. Now an international, multicenter cohort study finds that a genetic test to screen for trisomy 21 or 18 from a maternal blood sample is almost 100% accurate.

New region on the X chromosome plays a role in migraine

New hope has arrived for migraine sufferers following a Griffith University study with the people of Norfolk Island. Led by Professor Lyn Griffiths from the University's Griffith Health Institute, the team has identified a new region on the X chromosome as playing a role in migraine.

Researchers identify chromosomal make-up of human eggs

In a groundbreaking study, Yale School of Medicine researchers and colleagues at the University of Oxford have identified the chromosomal make-up of a human egg. This discovery may soon allow them to avoid using abnormal - or aneuploid - eggs during infertility treatments, and instead to pick eggs that are healthy enough for a successful in vitro fertilization (IVF) cycle.

Distinctive protein pathways in certain leukemia patients

Scientists at Rice University and the University of Texas MD Anderson Cancer Center have successfully profiled protein pathways found to be distinctive to leukemia patients with particular variants of the disease.

Gender link discovered for colorectal cancer

Researchers have identified three new colorectal cancer risk loci, including one on the X-chromosome, bringing the total number of independent loci associated with the disease to 20.

JTCC to present latest findings in blood-cancer research at ASCO annual meeting

Physicians and researchers at John Theurer Cancer Center at HackensackUMC, one of the nation's top 50 cancer centers, will present the latest findings in blood-cancer research at the 2012 American Society of Clinical Oncology (ASCO) annual meeting in Chicago on June 1-5. Their involvement in these studies is part of John Theurer Cancer Center's continued focus to bolster its research program.

Researchers uncover insights into rare genetic disorders

Researchers studying rare genetic disorders have uncovered insights into those diseases in biological structures that regulate chromosomes when cells divide. Focusing on the cohesin complex, a group of proteins forming a bracelet that encircles chromosome pairs, scientists have discovered mutations that disrupt cohesin, causing a recently recognized class of diseases called cohesinopathies.

Naphthalene exposure may increase risk of chromosomal aberrations in children

According to a new study, children exposed to high levels of the common air pollutant naphthalene are at increased risk for chromosomal aberrations (CAs), which have been previously associated with cancer. These include chromosomal translocations, a potentially more harmful and long-lasting subtype of CAs.

CDKN1C gene mutation contributes to IMAGe syndrome

A gene previously linked to too much growth in patients has now also been linked to growth restriction. Different forms of the gene can lead to very different conditions, according to research published today in the journal Nature Genetics.

UCLA geneticists identify mutation responsible for IMAGe syndrome

UCLA geneticists have identified the mutation responsible for IMAGe syndrome, a rare disorder that stunts infants' growth. The twist? The mutation occurs on the same gene that causes Beckwith-Wiedemann syndrome, which makes cells grow too fast, leading to very large children.

Scientists show how hemizygous deletion can contribute to cancer

Chromosomal deletions in DNA often involve just one of two gene copies inherited from either parent. But scientists haven't known how a deletion in one gene from one parent, called a "hemizygous" deletion, can contribute to cancer.

X-chromosome involved in development of bowel cancer

Scientists have shown for the first time that one of the sex chromosomes is involved in the development of a cancer that can afflict both genders, according to a Cancer Research UK-funded study in Nature Genetics.

RUB researchers gain new insights into mechanisms of cardiovascular disease

Malformed desmin proteins aggregate with intact proteins of the same kind, thereby triggering skeletal and cardiac muscle diseases, the desminopathies. This was discovered by researchers from the RUB Heart and Diabetes Center NRW in Bad Oeynhausen led by PD Dr. Hendrik Milting in an interdisciplinary research project with colleagues from the universities in Karlsruhe, Würzburg and Bielefeld. They report in the Journal of Biological Chemistry.

Researchers identify single gene that controls aging, inflammation and cancer

Researchers at NYU School of Medicine have, for the first time, identified a single gene that simultaneously controls inflammation, accelerated aging and cancer.

Researchers identify genetic marker linked with smoking quantity in African Americans

In a step toward understanding possible genetic differences in smoking behaviors, a team of researchers co-led by SRI International has identified a genetic marker associated with smoking quantity in people of African ancestry.
