DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Study identifies how cancer cells transform macrophages into supporters of their growth

A Ludwig Cancer Research study has identified a means by which cancer cells engineer the conversion of immune cells known as macrophages from destroyers of tumors to supporters of their growth and survival.

Study provides a specific target to tackle breast cancer relapse

Molecular targets for therapies that could prevent breast cancer recurrence have been identified by a group of German, Norwegian and British scientists who analyzed tumour cells that proved resistant to the original treatment.

Development of light-based tool for the inactivation of SARS-CoV-2

Researchers from EMIT bio have developed a biological light unit that can sterilize surfaces, killing SARS-CoV-2.

Role of SARS-CoV-2 infection biomarkers in HIV replication

A new study investigates the role of the S100A8/A9 complex in the replication of HIV.

Nanoparticle-mediated, slow-release delivery of TT-10 enhances heart attack recovery in mouse model

A heart attack kills heart muscle cells, leading to a scar that weakens the heart, often leading to eventual heart failure. The lack of muscle repair is due to the very limited ability of mammalian heart muscle cells to proliferate, except for a brief period around birth.

New Spex Genomax 2050 accelerates the extraction of molecules

Obtain fast and efficient extraction of nucleic acids, proteins, and other molecules with the new Spex® Genomax® 2050; a high-throughput plant and animal tissue homogenizer and cell lyser designed for rapid cell disruption, cell lysis and tissue homogenization through bead beating.

Machine learning approach effective in predicting antibiotic resistance spread

Genes aren't only inherited through birth. Bacteria have the ability to pass genes to each other, or pick them up from their environment, through a process called horizonal gene transfer, which is a major culprit in the spread of antibiotic resistance.

Researchers find a new way to analyze diseased and healthy cells from brain tumor patients

Scientists studying the most common and aggressive type of brain tumor in adults have discovered a new way of analyzing diseased and healthy cells from the same patient.

Cell-free DNA can help detect measurable residual disease in children with medulloblastoma

Scientists at St. Jude Children's Research Hospital have shown that cell-free DNA from cerebrospinal fluid (CSF) can be used to detect measurable residual disease (MRD) in children treated for the brain tumor medulloblastoma.

CAR-T cell treatment's efficacy in hematological malignancies predicted by epigenetics

One in five cancers affects blood cells and lymph nodes, causing leukemias and lymphomas, respectively. Although their treatment with drugs has led to a great advance in their cure, there are cases where there is no clinical response or resistance to them is generated.

Improper Z-RNA recognition contributes to pathogenesis of Aicardi-Goutières syndrome

Like DNA, RNA molecules contain information through unique combinations of four different nucleotides. However, through a molecular process called RNA editing, chemical changes can be made to adenosine nucleotides that convert them to a nucleotide called inosine by enzymes known as adenosine deaminases (ADARs).

Innovative method greatly simplifies the complexity of delivering vaccines

Future vaccine delivery may rely on everyday items like BBQ lighters and microneedles, thanks to the ingenuity of a team of Georgia Institute of Technology and Emory University researchers.

21 Oct 2021

Novel pathways to target breast cancer identified

A pathway helping the breast cancer protein BRCA1 repair damaged DNA has been identified by University of Queensland researchers in a study that will inform future targeted therapies.

20 Oct 2021

Discovery could help develop a new treatment strategy for patients with melanoma

A new study led by Yale Cancer Center researchers shows that the enzyme KDM5B suppresses anti-melanoma immunity.

20 Oct 2021

Red blood cells play a much larger role in the immune system than previously thought

New research has revealed that red blood cells function as critical immune sensors by binding cell-free DNA, called nucleic acid, present in the body's circulation during sepsis and COVID-19, and that this DNA-binding capability triggers their removal from circulation, driving inflammation and anemia during severe illness and playing a much larger role in the immune system than previously thought.

20 Oct 2021

Suggested mechanism of SARS-CoV-2 infection inhibition by Mitoxantrone

A group of researchers performed a drug repurposing screen on an FDA-approved anti-cancer drug named Mitoxantrone.

20 Oct 2021

Research may lead to breakthroughs in combating cancer drug resistances

New research has revealed the differences in mechanism behind cancer’s resistance to the major class of anti-cancer drugs known as nucleoside analogues.

20 Oct 2021

Researchers identify new gene variants that may cause inherited retinal dystrophies

An international team of researchers, led by scientists at University of California San Diego and Shiley Eye Institute at UC San Diego Health, has broadened and deepened understanding of how inherited retinal dystrophies (IRDs) affect different populations of people and, in the process, have identified new gene variants that may cause the diseases.

Understanding how brain cells talk could help find new treatments for neurological, psychiatric conditions

Experts from the University of Nottingham have discovered that reversing the modification of molecular messages at synapses in the human brain, may contribute to reversible mental health conditions such as anxiety, and memory diseases such as dementia.
