Inherited or transmitted gut microbes affect skeletal development in animals

Gut microbes passed from female mice to their offspring, or shared between mice that live together, may influence the animals' bone mass, says a new study published today in eLife.

Study monitors spatial shifts of liver gene expression in relationship to the circadian clock

Nothing in biology is static. Biological processes fluctuate over time, and if we are to put together an accurate picture of cells, tissues, organs etc., we have to take into account their temporal patterns. In fact, this effort has given rise to an entire field of study known as "chronobiology".

Study sheds new light on the role of MLL4 gene in Kabuki syndrome

Scientists have known for years that mutations in the MLL4 gene can cause Kabuki syndrome, a rare developmental disorder.

Master Regulator proteins control cancer transcriptional identity

Thousands of different genetic mutations have been implicated in cancer, but a new analysis of almost 10,000 patients found that regardless of the cancer's origin, tumors could be stratified in only 112 subtypes and that, within each subtype, the Master Regulator proteins that control the cancer's transcriptional state were virtually identical, independent of the specific genetic mutations of each patient.

Researchers identify biomarkers in sperm for paternal offspring autism susceptibility

Biomarkers in human sperm have been identified that can indicate a propensity to father children with autism spectrum disorder.

NIST compiles the first detailed tutorial on DNA origami

In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3D structures, including miniature biosensors and drug-delivery containers.

Using genomic analysis to map the introduction of SARS-CoV-2 virus in the UK

The SARS-CoV-2 virus was introduced to the United Kingdom well over 1,000 times in early 2020, according to researchers who analyzed more than 50,000 viral sequences from the first wave of the COVID-19 pandemic in the UK.

Researchers develop new statistical method that generates significant genetic insights

Pleiotropy analysis, which provides insight on how individual genes result in multiple characteristics, has become increasingly valuable as medicine continues to lean into mining genetics to inform disease treatments. Privacy stipulations, though, make it difficult to perform comprehensive pleiotropy analysis because individual patient data often can't be easily and regularly shared between sites.

Study shows how new antibiotic resistance genes arise from random DNA sequences

An important and still unanswered question is how new genes that cause antibiotic resistance arise. In a new study, Swedish and American researchers have shown how new genes that produce resistance can arise from completely random DNA sequences. The results have been published in the journal PLOS Genetics.

Researchers develop a gene signature for predicting survival in patients with peritoneal carcinomatosis

Researchers from The University of Texas MD Anderson Cancer Center who profiled more than 45,000 individual cells from patients with peritoneal carcinomatosis (PC), a specific form of metastatic gastric cancer, defined the extensive cellular heterogeneity and identified two distinct subtypes correlated with patient survival.

Scientists trace genetic roots of Chiari 1 malformation

About one in 100 children has a common brain disorder called Chiari 1 malformation, but most of the time such children grow up normally and no one suspects a problem.

Polygenic risk scores from multi-population data could improve IBD predictions

Using genetic data from nearly 30,000 people, Mount Sinai researchers have built risk scores from a combination of datasets representing distinct ancestral populations that improve prediction of risk for inflammatory bowel diseases (IBD) including Crohn's disease and ulcerative colitis. The study was published in Gastroenterology on December 24.
