Simultaneous mutation of two nonessential genes can cause cancer cell death

A Ludwig Cancer Research study has identified a new instance in which the simultaneous mutation of two nonessential genes - neither of which is on its own vital to cell survival - can cause cancer cell death.

Exploiting 'synthetic lethality' to identify cancer targets

With advances in genome sequencing, cancer treatments have increasingly sought to leverage the idea of "synthetic lethality," exploiting cancer-specific genetic defects to identify targets that are uniquely essential to the survival of cancer cells.

New strategy may help guard beta cells, slow the onset of type 1 diabetes

Type 1 diabetes occurs when a person's own immune system destroys insulin-producing beta cells in the pancreas. In recent years, scientists have learned how to grow large volumes of replacement beta cells, but the researchers are still trying out many options to protect these cells against the immune attack.

EBV viral genome alters the host epigenetic landscape to drive stomach cancer

The Epstein-Barr virus (EBV), one of the most common human viruses, is associated with about 8-10 per cent of stomach -- or gastric -- cancers, the third leading cause of cancer death globally.

SwRI, UTSA researchers receive grant to create powerful, cost-effective malaria treatment

Southwest Research Institute and The Uni-versity of Texas at San Antonio are working to synthesize novel highly potent derivatives of the antimalarial drug artemisinin with the goal of creating a powerful, cost-effective malaria treatment.

Study reveals manifold applications of cytokine transcriptional response modules in COVID-19

In a recent bioRxiv* study, UK researchers used interleukin modules to investigate the pathology of coronavirus disease (COVID-19).

New approach could enable wider adoption of COVID-19 testing for diagnosis in research laboratories

Clinician-scientists at Nanyang Technological University, Singapore's (NTU Singapore) Lee Kong Chian School of Medicine (LKCMedicine) have demonstrated a way to improve the speed, handling time and cost of COVID-19 laboratory tests.

Study identifies mechanisms that underlie olfactory symptoms of COVID-19

A new study of human olfactory cells has revealed that viral invasion of supportive cells in the nasal cavity might be driving the loss of smell seen in some patients with COVID-19.

Olfactory cell types are most vulnerable to COVID-19 infection, shows study

Temporary loss of smell, or anosmia, is the main neurological symptom and one of the earliest and most commonly reported indicators of COVID-19.

Researchers identify TLR7 gene that predisposes elderly patients to severe COVID-19

Current observations suggest that the coronavirus SARS-CoV-2 causes severe symptoms mainly in elderly patients with chronic disease.

Researchers discover new method to treat herpes viruses

Researchers at Lund University in Sweden have discovered a new method to treat human herpes viruses. The new broad-spectrum method targets physical properties in the genome of the virus rather than viral proteins, which have previously been targeted.

Researchers use optogenetics to activate and inactivate signaling pathways

Proper embryonic development of the fruit fly Drosophila melanogaster is governed by patterns of protein activity bequeathed to the fertilized egg by its mother.

New model may explain why certain cancer cells are resistant to therapy

Cancer's knack for developing resistance to chemotherapy has long been a major obstacle to achieving lasting remissions or cures.

New genome-editing technologies can help understand disease-associated genetic mutations

New genome-editing technologies developed by researchers in J. Keith Joung's laboratory at the Massachusetts General Hospital (MGH) have the potential to help understand disease-associated genetic mutations that are based on C-to-G (cytosine to guanine) single base changes.

Modulating immunometabolic processes to control lung infection

When drugs to kill microbes are ineffective, host-directed therapy uses the body's own immune system to deal with the infection.

Epigenomic modifications play key role in the development of lung tumors

As cancer cells evolve, many of their genes become overactive while others are turned down. These genetic changes can help tumors grow out of control and become more aggressive, adapt to changing conditions, and eventually lead the tumor to metastasize and spread elsewhere in the body.

Gene in fat cells plays a key role in regulating insulin sensitivity

Deleting a key gene in mice in just their fat made tissues throughout these animals insulin resistant, in addition to other effects, a new study by UT Southwestern researchers shows.

People who carry the Neandertal variant of ion channel experience more pain

As several Neandertal genomes of high quality are now available researchers can identify genetic changes that were present in many or all Neandertals, investigate their physiological effects and look into their consequences when they occur in people today.

Gene signature explains why 18F-FDG imaging performs better for PSMA-suppressed prostate cancer patients

Scientists have uncovered the genomic signature to explain why 18F-FDG imaging performs better than PSMA-targeted imaging for prostate cancer patients with low or no expression of the prostate-specific membrane antigen (PSMA).

Mouse model of pancreatic cancer recreates two subtypes of human disease

Scientists at Cold Spring Harbor Laboratory (CSHL) have created the first mouse model of pancreatic cancer that recreates two subtypes of the human disease.
