Molecular Biology News and Research

RSS

Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

First wiring map of neurons in insect brain complete

Researchers have built the first ever map showing every single neuron and how they’re wired together in the brain of the fruit fly larva.

New model simplifies the understanding of vascular malformations

Our bodies are made up of 60,000 miles of complex pipes that play a vital role in transporting nutrients throughout our bodies, performing waste disposal, and supplying our organs with fresh oxygen and blood.

DNA methylation for precise gene expression regulation

If the genome is viewed as a guidebook for how a cell should operate, then annotations, highlights, and bookmarks are included on every page.

Accelerating the structure-guided discovery of chemogenetic tools

In order to more fully understand how diseases arise in the brain, scientists must unravel the intricate way neurons relay messages (either chemical or electrical) along a complex web of nerve cells. One way is by using a tool called DREADDs, which stands for Designer Receptors Activated by Designer Drugs.

New method triggers and analyzes the dynamics of brain protein linked to Alzheimer’s

Scientists are not yet clear on how the tau protein changes from a benign protein essential for normal function in our brains into the toxic neurofibrillary tangles that are a signature of Alzheimer's and other neurodegenerative diseases.

UChicago scientists shed light on the longstanding puzzle of RNA methylation

University of Chicago scientists have discovered a new wrinkle in our understanding of how our genes work.

Researchers discover target enzyme for blast disease

A fungus that plagues rice crops worldwide gains entry to plant cells in a way that leaves it vulnerable to simple chemical blockers, a discovery that could lead to new fungicides to reduce the substantial annual losses of rice and other valuable cereals.

Research provides insight into the regulation of heartbeats

UT Southwestern Medical Center researchers have mapped gene control elements in specialized cardiac cells responsible for coordinating heartbeats. The findings of the genome exploration study, published in The Journal of Clinical Investigation, provide insight into how heartbeats are regulated and could impact diagnosis and risk prediction for a variety of common arrhythmias.

Two-step screening of aroma compounds reveals a novel and effective modulator of dendritic cells

Dendritic cells (DCs) are important players of the immune system with important functions such as the identification of infectious pathogens, production of cytokines (chemical signalers of the immune system), presentation of antigens to activate T-cells, and more.

Genetic variants that increase the risk of ADHD identified

Why are some people diagnosed with ADHD while others are not? And when is the seed of ADHD sown, in life or the womb?

Protein that facilitates cancer-causing viruses dodge the immune system

Numerous cancers have been related to the viruses Epstein-Barr virus (EBV) and Kaposi sarcoma-associated herpesvirus (KSHV). For the first time, UNC School of Medicine researchers have shown that these viruses elude the innate immune response by using a human protein called barrier-to-autointegration factor 1, or BAF, which enables the viruses to propagate and cause disease.

New hexameric structure of the protein triggering antibiotic resistance discovered

All living organisms require DNA replication to ensure the genetic integrity of the following generation. On the other hand, bacteria have the ability to horizontally transfer genetic information to other bacteria.

Structure of amyloid fibers formed by the protein hnRNPDL-2 determined

Using high-resolution cryo-electron microscopy (cryo-EM), UAB researchers determined the structure of amyloid fibers formed by the protein hnRNPDL-2, which has been linked to limb-girdle muscular dystrophy type 3 and concluded that the protein’s inability to form amyloid ﬁbers, rather than aggregation, would be the cause of the disease.

Groundbreaking discovery could lead to new ways of controlling gene regulation

UT Southwestern Medical Center researchers have discovered a method cells use to turn genes on and off that involves portions of proteins whose function has long been a mystery.
