Autophagy News and Research

RSS

Autophagy is a normal process in which a cell destroys proteins and other substances in its cytoplasm (the fluid inside the cell membrane but outside the nucleus), which may lead to cell death. Autophagy may prevent normal cells from developing into cancer cells, but it may also protect cancer cells by destroying anticancer drugs or substances taken up by them.

New mouse model mimics human pathology of childhood restrictive cardiomyopathy

Severe childhood restrictive cardiomyopathy is a condition that causes the muscles in the walls of the heart to become stiff, so that the heart is unable to fill properly with blood.

Researchers review the therapeutic potential of resveratrol nasal formulations in COVID-19

In a recently published article in the journal Frontiers in Immunology, scientists have reviewed the existing literature on antiviral and anti-inflammatory efficacy of resveratrol-based inhaled formulations in preventing SARS-CoV-2 infection and reducing COVID-19 severity.

Researchers clarify cellular processes related to radiation resistance of pancreatic cancer cells

Pancreatic cancer is one of the deadliest cancer subtypes not just because it is difficult to diagnose early, but because it is inherently resistant to chemotherapy and radiotherapy.

Researchers uncover molecular mechanism linking Parkinson’s disease with COVID-19

The study findings reveal that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection results in abnormal modification of some lung proteins, which are subsequently transported to the brain via exosomes. In the brain, these modified lung proteins disrupt the normal functioning of proteins that are related to Parkinson’s disease.

Study explores therapeutic potential of exploiting autophagy cascade against COVID-19

Researchers recently reviewed current knowledge on links between autophagy and coronaviruses and how this knowledge can be used to repurpose autophagy modulators as potential treatment options for COVID-19. The review is published in the journal Frontiers in Microbiology.

Researchers identify new approach to clear toxic Huntingtin protein

Researchers world-wide are focused on clearing the toxic mutant Huntingtin protein that leads to neuronal cell death and systemic dysfunction in Huntington's disease (HD), a devastating, incurable, progressive neurodegenerative genetic disorder.

Phosphatidic acid is a key common substrate for hepatitis C and SARS-CoV-2 replication

A new study, released as a preprint on the bioRxiv* server, focuses on the lipid molecule called phosphatidic acid (PA), showing its crucial role in the replication of this virus, and thus its potential as a target for therapeutic intervention.

Researchers examine potential SARS-CoV-2 antivirals using a drug repurposing library

A new study deals with the screening of the Drug Repurposing Hub (DRH) library for identifying small compounds which are capable of inhibiting SARS-CoV-2 using both in vitro and in vivo experimental studies. These molecules could be used for designing a novel therapeutic system against SARS-CoV-2 infection.

Targeting brain protein may lead to new therapeutic approaches for neurodegenerative disorders

Neurological disorders are the number one cause of disability in the world, leading to seven million deaths each year. Yet few treatments exist for these diseases, which progressively diminish a person's ability to move and think.

Parkinson's disease, type 2 diabetes, and cancer share the same pathway, shows study

When cells are stressed, chemical alarms go off, setting in motion a flurry of activity that protects the cell's most important players. During the rush, a protein called Parkin hurries to protect the mitochondria, the power stations that generate energy for the cell.

High expression of cell death genes may increase risk of early death from lung cancer

Patients with a high number of genes most associated with pathways that lead to cell death in lung cancer are at increased risk of dying early from their disease, researchers report.

Researchers reveal novel therapeutic target in the treatment of certain cancers

Mount Sinai Researchers Find "Removal of AKAP11 Protein by Autophagy as a key to Fuel Mitochondrial Metabolism and Tumor Cell Growth through activating protein kinase A (PKA) (Patent pending)"

Researchers examine circRNAs encoded by MERS-CoV, SARS-CoV-1 and SARS-CoV-2

New research published in Briefings in Bioinformaticsm has identified thousands of circRNAs in Betacoronaviruses, including MERS-CoV, SARS-CoV-1, and SARS-CoV-2, from the RNA-sequencing data of viral infections. These coronaviruses have a similar genomic structure with a diverse circRNA coding ability. Researchers have also systematically characterized circRNAs in coronaviruses, with regard to their size, sequence feature, expressions, genome, location preference, and functions. This opens the door to further explore and understand the mode of action of individual circRNAs in coronaviruses.

Study reveals arsenal used by protozoans to make leishmaniasis more severe

Researchers have succeeded in revealing the arsenal used by protozoans of the genus Leishmania in human cells to make leishmaniasis more severe, especially in cases of the mucocutaneous variety of the disease, which can cause deformations in patients.

Pancreatic cancer cells use adaptive mechanisms to avoid death by starvation

In new findings published online March 18, 2021 in the journal Cancer Cell, an international team of researchers, led by scientists at University of California San Diego School of Medicine and Moores Cancer Center, describe how pancreatic cancer cells use an alternative method to find necessary nutrients, defying current therapies, to help them grow and spread.
