Marine Bacteria Could Hold Key to Fighting Tuberculosis

The surprising discovery of a bacterium in a marine sponge from the Great Barrier Reef with striking similarity to Mycobacterium tuberculosis, the pathogen responsible for tuberculosis (TB), could unlock and inform future TB research and treatment strategies.

The Molecular Process That Causes MS and Autoimmune Diseases

A human immune system suppressor known as “regulatory T cells” was first identified more than 20 years ago by a research team working in the lab of Yale researcher David Hafler, who was at Harvard at the time.

Evolution of Blood Sugar Regulation in Neotropical Bats

Humans must regulate blood sugar concentrations to stay healthy and to fuel our cells. Too little or too much can cause serious health complications, and high blood sugar is a hallmark of the metabolic condition, diabetes. New research from the Stowers Institute for Medical Research may enable potential solutions to metabolic disease by turning to evolution and to bats.

Bacterial Cells Pass on Non-Genetic Traits Across Generations

Bacterial cells can "remember" brief, temporary changes to their bodies and immediate surroundings, a new Northwestern University and University of Texas-Southwestern study has found.

Sae2 Regulates Critical DNA Repair Functions in Yeast

DNA damage is a cellular phenomenon that introduces structural abnormalities in double-stranded DNA. External factors, such as radiation or chemical agents, as well as internal factors, such as blocked DNA replication, can generate double-strand breaks (DSBs) in DNA.

The Influence of 'Silent' Mutations on Genetic Disorders

Genetic disorders -; like cystic fibrosis and Huntington's disease -; are considered incurable, with gene mutations occurring in essentially every cell of the body.

Clock Genes Drive Evolutionary Split in Two Moth Species

Investigating moth speciation, this research highlights the impact of clock genes on behavior, providing a rare glimpse into evolutionary processes.

Stem Cell Research Sheds Light on Rare Pediatric Condition

Scientists have identified mutations in the DENND5A gene that cause severe neurodevelopmental issues in infants, leading to improper brain cell division during development.

RNA Interference Drugs Offer Faster, More Effective Alternative to Traditional Drug Discovery

Alnylam's RNA interference platform accelerates drug discovery by targeting RNA transcripts, addressing complex diseases with innovative therapeutic strategies.

CDCA7's Role in DNA Methylation Maintenance Revealed in Recent Study

DNA methylation is a process in which a methyl group is attached to the cytosine base of the DNA molecule, and a major way that DNA is epigenetically marked. Epigenetic modifications can act as on-off switches to regulate gene expression and help generate diverse cell types without changing the underlying DNA sequence. It is how the body ensures that brain-related genes don't get turned on in heart cells, for example.

Rare CCDC201 Genotype Significantly Affects Menopause Onset in Women

Scientists at deCODE genetics and collaborators, have identified a sequence variant in the CCDC201 gene that when inherited from both parents homozygous causes menopause on average nine years earlier.

Computational Modeling and Experimental Findings on Nucleosome Constraining in Mitosis

Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism by which DNA condenses during mitosis is still poorly understood. Researchers recently tracked small stretches of DNA wound around histone proteins, called nucleosomes, to better characterize nucleosome behavior during cell division.

Engineering Purple Bacteria for Enhanced Bioplastic Synthesis

In a world overrun by petroleum-based plastics, scientists are searching for alternatives that are more sustainable, more biodegradable and far less toxic to the environment.

New Human Intestinal Immuno-Organoids Reveal Insights into Immune Cell Dynamics and Cancer Immunotherapy

Research on intestinal immuno-organoids reveals their potential in modeling immune interactions and studying intestinal diseases linked to cancer therapies.

Clinical Trials Supported by Genetics Show Higher Success Rates

Analyzing 28,561 discontinued trials, the study reveals safety and efficacy concerns as major discontinuation factors, with genetics playing a crucial role.

New Discovery in Mitochondrial DNA Regulation May Halt Heritable Disease Onset

University of Queensland researchers have discovered a mechanism in DNA that regulates how disease-causing mutations are inherited.

New SPARXS Technique Revolutionizes DNA Sequence Analysis

"DNA, RNA and proteins are the key players to regulate all processes in the cells of our body," Leiden Professor John van Noort explains. "To understand the (mis-)functioning of these molecules, it is essential to uncover how their 3D structure depends on their sequence and for this it is necessary to measure them one molecule at a time. However, single-molecule measurements are laborious and slow, and the number of possible sequence variations is massive."

The Complex Link Between DNA Modification and ALS

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease which remains incurable. The disease is characterized by the selective degeneration of upper motor neurons in the motor cortex as well as the lower motor neurons in the brainstem and spinal cord. The cause of ALS remains unknown in 90 percent of cases, which are referred to as sporadic ALS because there is no family history for the disease. Cumulative evidence suggests that sporadic ALS may result from complex interactions between genetic susceptibility and aging.

Mother's Gut Microbiome Key to Baby's Brain Development

A study in mice has discovered that the presence of Bifidobacterium breve bacteria in the mother's gut during pregnancy promotes healthy brain development in the fetus.
