A Spanish study shows epigenetic markers in the DNA can predict COVID-19 disease severity. Many of these markers are found in genes linked to immune function and the release of interferon in response to viral infection such as AIM2 and HLA-C.

Leprosy Drug Shows Potential as At-Home Treatment for COVID-19

Clofazimine, which was discovered in 1954, is FDA approved and on the World Health Organization’s List of Essential Medicines. The drug’s utility for COVID-19 was initially identified by screening more than 12,000 drugs from the ReFRAME drug library.

Sweat Sensor Could Predict Cytokine Storm in COVID-19 Patients

A new sweat sensor can detect seven inflammatory proteins seen at high levels in patients experiencing the kind of extreme immune reaction seen in COVID-19 and in some flu patients, which researchers hope will speed up treatment.

Risk of Lung Cancer Linked to Specific Variants

The researchers identified 25 new rare pathogenic variants associated with lung cancer susceptibility and validated five of those variants. Of those five, two variants involved genes with known connections to lung cancer risk, ATM and MPZL2. Three variants involved novel lung cancer susceptibility genes, POMC, STAU2 and MLNR.

Nebulizer Can Deliver CRISPR-Based Treatment Targeting COVID-19 and Influenza

The researchers used mRNA technology to code for Cas13a, which destroys parts of the RNA genetic code that viruses use to replicate in cells in the lungs. Using a guide strand, researchers can provide a map that basically tells the Cas13a protein where to attach to the viruses’ RNA and begin to destroy it.

New Genetic Markers of Lung Cancer Could Lead to More Personalized Treatments

The researchers found that mutations in KMT2C and KMT2D make non-small cell lung cancer more sensitive to Poly (ADP-ribose) polymerase (PARP) inhibitors, which are already approved for treating prostate, pancreatic, ovarian, and breast cancer patients.

Gut Microbes That Influence Neurological Disorders May Inspire New Therapies

Researchers at the Baylor College of Medicine report that they have found that microbes in the gut may contribute to certain symptoms associated with complex neurological disorders, which also suggests that microbe-inspired therapies may one day help to treat them.

Machine Learning Method Predicts New Cancer Genes

Known as Explainable Multi-Omics Graph Integration (EMOGI), the machine learning method predicted 165 new cancer genes by combining multiomics pan-cancer data—such as mutations, copy number changes, DNA methylation and gene expression—together with protein–protein interaction (PPI) networks.

U.S. Agencies Push for Pause of J&J COVID-19 Vaccine After Patients Develop Rare Blood...

The CDC’s Advisory Committee on Immunization Practices (ACIP) will meet Wednesday to review the six reported cases to assess their potential significance. The FDA plans to conduct its own investigation and will also review the CDC’s analysis.

Intestinal Organoids Developed to Test New Drugs for COVID-19

SARS-CoV-2 affects many parts of the body. Although the primary manifestations of COVID-19 involve the respiratory system, gastrointestinal effects may play a critical role in both disease severity and transmission.
Alzheimer's disease: the amyloid-beta peptide accumulates to amyloid fibrils that build up dense amyloid plaques.

Increasing ABCC1 Gene Expression Could Help Prevent Alzheimer’s Disease

The ABCC1 protein has the ability to break down amyloid plaques in Alzheimer’s disease and researchers show in a new study that increasing expression of this gene may even prevent the neurodegenerative disease from developing in the first place.

Machine Learning Algorithm Predicts Cancer Drug Efficacy

A method known as 'Drug Ranking Using Machine Learning' was developed at Queen Mary University in London and is based on machine learning analysis of protein omics data in cancer cells. It was created based on training responses of cancer cells to a panel of cancer drugs and can predict the most appropriate one to use to treat a particular cancer.

New Biomarker of Pancreatic Cancer May Predict Benefit of Tumor-Penetrating Peptide

According to the new study, the tumor-penetrating peptide known as iRGD appears to enhance the effects of chemotherapy, reducing metastasis, and increasing survival, to a degree determined by levels of β5 integrin. Essentially, β5 integrin gives chemotherapeutic agents the opportunity to destroy the tumor from within.

Interferon-Stimulated Genes Limit SARS-CoV-2 Infection

The researchers’ analysis showed low expression of IFNAR2, or high expression of TYK2, are associated with life-threatening disease. Also, transcriptome-wide association in lung tissue revealed that high expression of the monocyte–macrophage chemotactic receptor CCR2 is associated with severe COVID-19.

Genome Sequencing Reveals Patterns of COVID-19 Spread in Elder Care Homes

The researchers conclude that isolating residents or staff when they develop symptoms is not sufficient to prevent within-care home spread once the virus has entered the care home. Certain measures may be required on an ongoing basis within care homes when there is sustained community transmission, even when no outbreak is suspected.
