Research: X and Y DNA swapping may occur more often than previously thought

It turns out that the rigid "line in the sand" over which the human sex chromosomes---the Y and X--- go to avoid crossing over is a bit blurrier than previously thought. Contrary to the current scientific consensus, Arizona State University assistant professor Melissa Wilson Sayres has led a research team that has shown that X and Y DNA swapping may occur much more often.

PERK inhibition can be a promising therapeutic strategy for neurodegenerative diseases

A major challenge in the field of neurodegeneration is the unclear understanding of neuronal dysfunction. Elucidation of these patho-mechanisms could result in the identification of novel therapeutic targets. In this article, Bell et al. present an exhaustive literature review highlighting the endoplasmic reticulum (ER) kinase PERK as a crucial contributor to systemic and neurodegenerative disorders.

Anti-anxiety drug reduces autistic features in Jacobsen syndrome mice

About half of children born with Jacobsen syndrome, a rare inherited disease, experience social and behavioral issues consistent with autism spectrum disorders. Researchers at University of California, San Diego School of Medicine and collaborators developed a mouse model of the disease that also exhibits autism-like social behaviors and used it to unravel the molecular mechanism that connects the genetic defects inherited in Jacobsen syndrome to effects on brain function.

Researchers identify new mutation responsible for spinocerebellar ataxia

Using the genetic information of two different families with three generations of disease, researchers have identified a new mutation responsible for a degenerative and ultimately fatal movement disorder. Through induced pluripotent stem cell techniques, researchers also grew neurons from one patient in the laboratory to be used in future experiments.

Gar genome helps identify genetic sequences shared by human disease genes and zebrafish

Led by Drs John Postlethwait and Ingo Braasch from the Institute of Neuroscience, University of Oregon, US, in collaboration with the Broad Institute, the study of the Spotted Gar (Lepisosteus oculatus) genome reveals that it is small and manageable. Furthermore, it lacks much shuffling and duplication that occurred in the 'main' fish ancestral line; it conserved its genome.

Researchers develop new technique to create naïve pluripotent stem cells

Scientists at the University of Cambridge have for the first time shown that it is possible to derive from a human embryo so-called 'naïve' pluripotent stem cells - one of the most flexible types of stem cell, which can develop into all human tissue other than the placenta.

Discovery could lead to better therapies for people with obsessive compulsive disorder

Research led by investigators in veterinary and human medicine has identified genetic pathways that exacerbate severity of canine compulsive disorder in Doberman pinschers, a discovery that could lead to better therapies for obsessive compulsive disorder in people.

Clinical validation study on MaterniT GENOME test published in American Journal of Obstetrics and Gynecology

Sequenom, Inc., a life sciences company committed to enabling healthier lives through the development of innovative products and services, today announced the publication of a clinical validation study on the MaterniT GENOME laboratory-developed test in the American Journal of Obstetrics and Gynecology.

New anti-ageing therapy may be effective against aplastic anaemia

Aplastic anaemia is a rare, and potentially fatal, disease of the blood, by which the bone marrow is unable to generate blood cells at the appropriate pace. Many forms of aplastic anaemia share an important link with the ageing process: the shortening of telomeres, structures that protect the ends of chromosomes.

Researchers analyze how Topo II enzyme may affect stability of genomes

While researchers are now familiar with how cancer begins—cells mutate and then multiply wildly out of control—it is still uncertain exactly how that mutation starts in the molecules of the cells.

African Americans with common genetic variants at increased risk for blood clots

New research published online today in Blood, the Journal of the American Society of Hematology (ASH), identifies common genetic variants predominantly found in African Americans that double their risk for blood clots.

Study reveals link between genomic instability, aneuploidy and cancer

A recent analysis of 43,205 human tumours unveiled that 68% of solid tumours are aneuploid, that is to say, they have an altered number of chromosomes. In recent years, scientists have attempted to clarify whether this aneuploidy contributes to tumour development or whether it is a co-lateral effect of the genomic instability of cancer cells, which increase the rate of mutations and the likelihood of cancer.

New technique allows better understanding of cellular stress reaction

Stress in the body's cells is both the cause and consequence of inflammatory diseases or cancer. The cells react to stress to protect themselves. Researchers at the University of Zurich have now developed a new technique that allows studying a fundamental response to stress in much more detail than previously possible: the ADP-ribosylation of chromatin.

Abnormal breakage of chromosomes in white blood cells triggers aggressive form of ALL

A research team led by St. Jude Children's Research Hospital scientists has discovered details of how the abnormal breakage and rearrangement of chromosomes in white blood cells triggers a particularly aggressive form of acute lymphoblastic leukemia (ALL). Such leukemias are cancers of white blood cells, in which genetic mutations trigger overproduction of immature cells, called lymphoblasts.

Aggression influences new nerve cell production in the brain

A group of neurobiologists from Russia and the USA, including Dmitry Smagin, Tatyana Michurina, and Grigori Enikolopov from Moscow Institute of Physics and Technology, have proven experimentally that aggression has an influence on the production of new nerve cells in the brain.

LouLou Foundation, Penn Med set up Program of Excellence to develop treatments for children with CDKL5

The London-based LouLou Foundation and the Orphan Disease Center of the Perelman School of Medicine at the University of Pennsylvania have established a Program of Excellence to develop effective treatments for children with CDKL5, a rare X-chromosome-linked genetic disorder that causes severe neuro-developmental impairment and early-onset, difficult-to-control seizures.

Study sheds light on mechanisms linked to formation of healthy egg cells in humans

Congenital disorders such as Down's syndrome could be better understood, following new insights into how healthy cells are formed.

Researchers identify new targets that may help prevent and cure colon cancer

When the audio on your television set or smart phone is too loud, you simply turn down the volume. What if we could do the same for the signaling in our bodies that essentially causes normal cells to turn cancerous? New discoveries by researchers at the Stephenson Cancer Center at the University of Oklahoma may point to new ways to do just that.

New gene cut-and-paste methods help correct disease-causing mutation in animal model

For the first time, researchers have treated an animal model of a genetic disorder using a viral vector to deliver genome-editing components in which the disease- causing mutation has been corrected.

Two studies shed new light on nature of tandem DNA repeat arrays

A pair of studies by a team of scientists has shed new light on the nature of a particular type of DNA sequences—tandem DNA repeat arrays—that play important roles in transcription control, genome organization, and development.
