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).

A novel method for predicting promising antiviral drug or vaccine targets

A novel method to predict the most promising targets for antiviral drugs or vaccines is based on the conformational changes viral glycoproteins go through during the process of recognition and binding to the host cell.

Hydroxychloroquine and azithromycin treatment in 80 COVID-19 patients: short-term outcomes

The COVID-19 pandemic is still spreading around the world and affecting nearly 2.4 million people, with over 164,000 dead so far. With neither vaccine nor proven therapeutic drug being available so far, the need of the hour is for effective treatment. Now, a new study reports the potential usefulness of a combination of hydroxychloroquine and azithromycin as a treatment in mild cases of COVID-19 infection and urges the need for further evaluation and widespread use if its findings are confirmed.

Study: Early changes in microbiome development can impact health and disease later in life

A team of researchers at Children's Hospital of Philadelphia (CHOP) has characterized how the gut microbiome develops in the first hours of infancy, providing a critical baseline for how changes in this environment can impact health and disease later in life.

Rare structural genetic variants could play a role in schizophrenia

Most research about the genetics of schizophrenia has sought to understand the role that genes play in the development and heritability of schizophrenia. Many discoveries have been made, but there have been many missing pieces.

Six novel coronaviruses found in bats

While the world grapples with the pandemic, which has spread to 185 countries and territories, infecting more than 2.15 million people and killing more than 143,000 people, a team of researchers at the Smithsonian's Global Health Program has found six novel coronaviruses in bats in Myanmar.

Are overactive immune cells causing COVID-19-related deaths?

While the COVID-19 pandemic is devastating many regions, the world over, a new paper published in the Journal of Experimental Medicine in April 2020 describes the possibility that the critical or very severe cases of COVID-19 are due to the production of neutrophil extracellular traps (NET) due to hyperactivated immune cells.

Solving the mystery of unidentified late-onset neurodegenerative disorder

When a patient with puzzling neurological symptoms enrolled in the Undiagnosed Diseases Network, researchers led by Dr. Hugo J. Bellen were set on solving the mystery.

Transposable elements play key role in genetic expression and evolution, study shows

Until recently, little was known about how transposable elements contribute to gene regulation. These are little pieces of DNA that can replicate themselves and spread out in the genome.

Study shows possible way to effectively deliver RNA drugs to tumors

In recent years, RNA molecules, with the ability to affect or turn off pathogenic genes, have become promising drug candidates in several areas.

Discovery of T cells response spectrum could new shed light on immune diseases

The discovery that immune T cells have a spectrum of responsiveness could shed light on how our immune system responds to infections and cancer, and what goes wrong in immune diseases.

Harnessing power of cancer gene could lead to first curative treatment for heart disease

Researchers trying to turn off a gene that allows cancers to spread have made a surprising U-turn. By making the gene overactive and functional in the hearts of mice, they have triggered heart cell regeneration.

The race is on for a coronavirus vaccine, 70 candidates, 3 at human trial stage

Amid the coronavirus disease (COVID-19) global pandemic that is infecting millions of people across the globe, hope sparks as the World Health Organization (WHO) reports that seventy vaccination trials for the novel coronavirus are underway, with three already at the human trial stage.

Potential cure for heart disease via cancer gene upregulation

Researchers have found that by switching on a gene that promotes the spread of cancers, they can enhance the regeneration of damaged heart muscle. The study results, published in April 2020 in the journal Nature Communication, could mark the beginning of curative therapy for heart disease.
