Study reveals chromosome-level changes that relate to drug resistance in melanoma

Precision therapies targeting melanoma and other cancers have improved patient survival, but tumors often stop responding to drugs, and recent studies point to changes in DNA – both inside and outside chromosomes – as a driving factor in tumor genesis as well as in treatment resistance.

Bioinformatics pipeline can be used to quickly identify SARS-CoV-2 therapeutics

In a new study, researchers developed a bioinformatics pipeline that uses RNA sequencing data to identify altered genes and signaling pathways affected by viral infection.

Statistical model builds SARS-CoV-2 interactome with miRNAs, protein-coding genes, and co-infecting microbes

A team of researchers recently developed a statistical modeling method known as multiple-layer crosstalk (MLCrosstalk).

Study identifies the role of early developmental gene in intracranial aneurysms

Mutations of a gene that regulates formation of blood vessels in the brain of vertebrates can lead to potentially deadly aneurysms in adults, Yale School of Medicine researchers report in the December issue of Nature Medicine.

Scientists find new way to reverse aggressive breast cancer into a less dangerous kind

Scientists at KAIST believe they may have found a way to reverse an aggressive, treatment-resistant type of breast cancer into a less dangerous kind that responds well to treatment.

Combination of two targeted drugs shows "clinically meaningful" activity in some malignant brain tumors

A combination of two targeted cancer drugs showed unprecedented, "clinically meaningful" activity in patients with highly malignant brain tumors that carried a rare genetic mutation, according to a clinical trial report by investigators from Dana-Farber Cancer Institute.

Study explores connections between COVID-19 severity and gene expression in immune cells

New research shows how genetic variations linked to severe cases of COVID-19 affect our immune cells.

Researchers receive $22 million grant for clinical trial that aims to reduce lung transplant rejection

Physicians at Washington University School of Medicine in St. Louis and Massachusetts General Hospital/Harvard Medical School in Boston have received a seven-year, $22 million grant from the National Institute of Allergy and Infectious Diseases of the National Institutes of Health to help lead a multicenter clinical trial evaluating whether a novel immunosuppressant can reduce the risk of organ rejection after a lung transplant.

What genes affect the COVID-19 gender imbalance?

Many studies have established that coronavirus disease 2019 (COVID-19) is more infective in men than women, and men are more at risk of severe disease. While some have suggested that behavioral differences could explain increased transmission to men, this does not explain the more morbid prognosis.

Study reveals how certain cells drive immunotherapy resistance in ovarian cancer mouse model

Immune checkpoint inhibitors are a type of cancer treatment that help the immune system's T cells recognize and attack tumors. But these immunotherapy drugs aren't effective against all cancers.

GPR126 gene may play an essential role in placental development, study reveals

Scientists working with an experimental mouse model at the Centro Nacional de Investigaciones Cardiovasculares have identified the essential role of the gene GPR126 in the development of the placenta during pregnancy.

Adaptive immunity in patients infected with SARS-CoV-2 Δ382 Variant

A comprehensive characterization of the immune responses between SARS-CoV-2 infected individuals with wildtype (WT) and Δ382 SARS-CoV-2.

Harvard researchers elucidate the underlying neuroanatomy of acupuncture

Acupuncture is a traditional Chinese technique that has been used for millennia to treat chronic pain and other health problems associated with inflammation, yet the scientific basis of the technique remains poorly understood.

Researchers identify an important mediator of thrombosis in CKD patients

Researchers have identified a potential new signaling pathway and enzyme that may help further the understanding of blood clot formation in chronic kidney disease patients and ultimately be targeted for therapeutic purposes.

Study uncovers how novel coronavirus disrupts normal cell defenses to hijack human host cells

A UBC-led research team has uncovered how the virus responsible for causing COVID-19 escapes destruction in infected cells, allowing SARS-CoV-2 to persist and continue spreading in the human body.

Lung cancer-associated fibroblasts could guide the design of personalized treatments

Three subtypes of cancer-associated fibroblasts (CAF) could guide the design of personalized treatment for lung cancer patients, according to a new study in Cancer Cell led by researchers at Massachusetts General Hospital.

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.

Research uncovers a new human sensory ability to detect sugars in the mouth

Most everyone understands that a major role of our sense of taste is to inform us when sugar is present in foods and beverages by eliciting sweetness on our tongues. A study led by the Monell Chemical Senses Center, published this month in PLOS ONE, identifies a new human sensory ability to detect sugars in the mouth with a molecular calorie detector, of sorts.
