Increased enzyme production by the liver causes fatty liver, obesity and insulin resistance

In mice that are given a high-fat diet, an increased production of the enzyme DPP4 by the liver promotes an increase in body fat, the development of fatty liver disease and insulin resistance.

Long non-coding RNAs could represent novel male infertility drug targets

Scientists have found distinctive portions of genetic material--known as lncRNAs--that help sperm develop. Male mice lacking a particular lncRNA have low sperm count, suggesting lncRNAs could represent novel infertility drug targets.

Study provides better understanding of how estrogen regulates gene expression

Estrogen hormones regulate gene expression. They achieve this by first binding to estrogen receptor in the cell nucleus, which triggers the recruitment of different molecules called coactivators in specific order.

New strategy allows researchers to identify potential treatments for altered levels of MeCP2

Having twice the normal amount of the protein MeCP2, a condition called MECP2 duplication syndrome, causes severe progressive neuropsychiatric disorders that include intellectual disability, autism spectrum disorders, motor dysfunction and other medical complications.

Variations in ancient mitochondrial DNA may play key role in predisposition to ASD

Mitochondria, the tiny structures inside our cells that generate energy, may play a key role in autism spectrum disorders (ASD).

Scientists make progress in predicting conditions that lead to toxic algal blooms

The disastrous 2015-16 Dungeness crab season, delayed and shortened by an unprecedented bloom of toxic algae, is a bitter memory for the West Coast fishing industry.

New international research project identifies subtypes of ocular melanoma

A new international research project, involving the University of Liverpool's leading eye cancer research group, has identified specific subtypes of ocular melanoma that will help develop improved management strategies and therapies in the future.

USC scientist finds new approach to prevent HIV infection

Medical treatment that targets human proteins rather than ever-mutating viruses may one day help HIV-positive people whose bodies have built a resistance to "cocktails" currently used to keep them healthy, according to a Keck School of Medicine of USC researcher.

Study findings could one day help doctors better predict survival of liver cancer patients

A new study of a molecule that regulates liver-cell metabolism and suppresses liver-cancer development shows that the molecule interacts with thousands of genes in liver cells, and that when levels of the molecule go down, which often happens during liver-cancer development, the activity of certain cancer-promoting genes goes up.

Research finds how omega-3 supplements dampen harmful inflammatory reactions

OMEGA-3: Omega-3 fatty acids, which we primarily get through eating fatty fish, have long been thought to be good for our health.

Researchers pursuing new approach to treating arthritis

Researchers at ETH Zurich, Empa and the Norwegian research institute SINTEF are pursuing a new approach to treating arthritis.

Id genes found to play crucial role in heart development

Researchers from Sanford Burnham Prebys Medical Discovery Institute (SBP), the Cardiovascular Institute at Stanford University and other institutions were surprised to discover that the four genes in the Id family play a crucial role in heart development, telling undifferentiated stem cells to form heart tubes and eventually muscle.

Research shows how social environment can influence brain development in female teenagers

Female teenagers living in neighbourhoods with wide salary gaps and a low-income household show changes to their brain maturation that could indicate a higher risk of developing mental illness in adulthood, suggests a recently published study by Canadian researchers.

New high-throughput technique accelerates chemical screening to prioritize toxicity testing

Researchers from North Carolina State University have developed a high-throughput technique that can determine if a chemical has the potential to activate key genes in seconds rather than the typical 24 hours or more.

Zika suppresses immune system during pregnancy to harm baby, report researchers

Scientists from the University of Southern California (USC) have discovered that the Zika virus works by suppressing a pregnant woman’s immune system so that the virus can spread and increase the chance of harming an unborn baby.

Genes that regulate oxytocin linked to sociality of young individuals

A group of researchers from the National University of Singapore has found that CD38 and CD157 genes that regulate oxytocin, the supreme human social hormone, are associated with the sociality of young individuals.

Scientists reveal existence of alternative bacterial quorum-sensing mechanism

Whether growing in a puddle of dirty water or inside the human body, large groups of bacteria must coordinate their behavior to perform essential tasks that they would not be able to carry out individually.

Researchers discover potential way to trigger regeneration, repair of damaged heart cells

New research has discovered a potential means to trigger damaged heart cells to self-heal. The discovery could lead to groundbreaking forms of treatment for heart diseases.

Women with a medical history of breast or ovarian cancer often fail to test for inherited genetic changes

A new study conducted by the UCLA Fielding School of Public Health, states that among nearly 4 million women in the United States who possess a medical history of ovarian cancer or breast cancer, 1.5 million have an increased risk of bearing some kinds of genetic mutations, which might increase the probability of causing additional cancers in the future.

Study: More than 80% of women at risk for breast, ovarian cancer have not taken simple genetic test

Of the nearly 4 million women in the United States who have had either breast cancer or ovarian cancer, at least 1.5 million have a high risk of carrying certain types of genetic mutations that could increase their risk for additional cancers in the future.
