A team led by a University of Delaware researcher has identified the protein essential for eye lens development and clear vision. Without the protein, eyes will form cataracts; with it, lens cells are cleared and ready to see. The work is providing fundamental new knowledge on the basic underlying mechanisms involved in eye development.
Researchers from Washington State University have discovered how a genetic mutation linked to hypertrophic cardiomyopathy disrupts the heart’s normal function. The study, which will be published May 18 in the Journal of General Physiology, reveals that the mutation prevents the heart from increasing the amount of force it produces when it needs to pump additional blood around the body.
Harvard Medical School researchers lead the first whole-genome analysis of ancient human DNA from Southeast Asia Study identifies at least three major waves of human migration into the region over the last 50,000 years, each shaping the genetics of Southeast Asia “to a remarkable extent” Findings reveal a complex interplay among archaeology, genetics and language
A small study of adults with the most common form of pancreatic cancer adds to evidence that patients with BRCA1 or BRCA2 gene mutations long linked to a high risk of breast cancer have poorer overall survival rates than those without the mutations.
A new study by researchers from the University of Chicago Medicine shows that bacterial signals are crucial to the development of a precursor condition to leukemia, which can be induced by disrupting the intestinal barrier or by introducing a bacterial infection.
Announcement of Case Western Reserve University and PAVmed signing a license agreement to commercialize EsoCheck technology which combines a non-invasive, cell-sampling device with highly accurate DNA biomarkers to detect Barrett's Esophagus. University Hospitals in Cleveland will implement use of the technology.
Researchers have uncovered important genomic data from the remains of an ancient giant ground sloth, or Mylodon darwinii, the emblematic creature named after Charles Darwin, whose discovery of fossilized remains in South America is considered to be one of his significant scientific achievements.
A team of biologists has determined how transcription factors, which guide gene regulation, function differently in embryonic development. The results help illuminate how cells acquire distinct functions as the embryo matures.
Scientists have unraveled a mystery on how genes are activated. Genes are blocked by structures known as nucleosomes, which package DNA. How do these roadblocks clear out to allow genes to turn on? Scientists have identified a key factor that unravels nucleosomes and clears the way. They say the finding is useful in understanding diseases such as cancer.
ThyroSeq® announced today that it will present performance data on utilization of ThyroSeq v3 Genomic Classifier at the upcoming American Association of Clinical Endocrinologists (AACE) 27th Annual Scientific & Clinical Congress.
Researchers found that four species of mice evolved from a common ancestor on Mindoro Island in the Philippines, making it the smallest known island where one kind of mammal has branched out into many more species.
Scientists exploring how to tame random gene fluctuations as the embryos that become our bodies start to form have identified a control switch in the vertebrate segmentation clock of developing zebrafish. The researchers report in Cell Reports their findings could uncover methods for modulating genetic signals to prevent birth defects or cancers rooted at the earliest stages of development.
A new study reveals that essential fats in the diet may play a role in regulating protein secretion in the muscles by changing the way genes associated with secretion act. The study is published ahead of print in Physiological Genomics.
Mutations in genes that help repair damage to DNA may aid in predicting the prognosis of patients with bladder and other related cancers, according to researchers.
From burning your palm on a hot pan handle to memorizing the name of a new acquaintance, “anytime you experience something, your neurons are active,” says Kelsey Tyssowski, a graduate student in genetics at Harvard Medical School. Different experiences stimulate different patterns of activity in brain cells. Researchers want to track these activity patterns to better understand how the brain makes sense of the world, but they’ve been limited by the transient nature of the activity and by the tiny fraction of neurons they’re able to study at once—only a few thousand out of an estimated 100 billion.
A team of biologists and computer scientists has adopted a time-based machine-learning approach to deduce the temporal logic of nitrogen signaling in plants from genome-wide expression data. The work potentially offers new ways to monitor and enhance crop growth using less nitrogen fertilizer, which would benefit human nutrition and the environment.
For years, researchers have known that a gene called EAK-7 plays an important role in determining how long worms will live. But it remained unclear whether the gene had a counterpart in humans and – if it did – how that human version would work. Now, researchers led by UCLA’s Dr. Paul Krebsbach are the first to characterize the mechanism of the human equivalent, which they call mammalian EAK-7, or mEAK-7.

Researchers from Columbia University have developed a new technique for the powerful gene editing tool CRISPR to restore retinal function in mice afflicted by a degenerative retinal disease, retinitis pigmentosa.
An article in AACN Advanced Critical Care explores how healthcare professionals can use genomic science to identify and counsel patients at risk for inherited disorders that are common causes for sudden cardiac death. The article is part of a symposium in the journal that explores the current state of genomics medicine as it relates to various diseases.
