Human cells can convert RNA sequences into DNA

Cells include machinery that replicates DNA into a new set, and this, in turn, develops into a newly formed cell.

New types of glial cells in the brain may treat neurodegenerative diseases

Researchers from the University of Basel have discovered two types of glial cells that may play an important role in brain plasticity and repair.

Study finds a link between progression of Alzheimer’s disease and corpuscles in cell nuclei

Studies conducted on patients’ tissue as well as mini-brains created from stem cells have provided a better insight into Alzheimer’s disease.

Misfolded tau proteins cause progressive degeneration in Alzheimer's disease

According to a study performed by researchers from the Van Andel Institute and the University of Pennsylvania, misfolded proteins that impair neurons in Alzheimer’s disease travel the “roads” of the brain, similar to a supply truck crossing the countryside.

Living cells can produce semi-interpenetrating polymer networks

Biomedical engineers at Duke University have demonstrated that a class of interwoven composite materials called semi-interpenetrating polymer networks (sIPNs) can be produced by living cells. The approach could make these versatile materials more biologically compatible for biomedical applications such as time-delayed drug delivery systems.

Naked mole rats' unique DNA repair mechanism helps prevent cancers, dementia

Scientists say naked mole rats - a rodent native to West Africa - may hold the key to new treatments for degenerative diseases such as cancer and dementia.

New research focuses on possible treatment options for childhood brain cancer

Medulloblastoma is a rare but devastating childhood brain cancer. This cancer can spread through the spinal fluid and be deposited elsewhere in the brain or spine.

New understanding of the molecular basis behind continuous stem cell activity in plants

An inter-university research group has succeeded in constructing the gene expression network behind the vascular development process in plants. They achieved this by performing bioinformatics analysis using the 'VISUAL' tissue culture platform, which generates vascular stem cells from leaf cells.

Scientists unravel the proteins that trigger some cancerous tumors

Even on a good day, DNA is constantly getting damaged. Nicks, scratches, breaks: the delicate strands that carry life's genetic code take a beating as they jumble about in the course of their work. If left untreated, errors accumulate, with fatal consequences -- such as cancerous tumors -- for the cell and the organism.

New “phase separation” protects against premature aging, neurological disorders

According to a new study, a mechanism through which an RNA, called NORAD, drives the Pumilio protein to create liquid droplets in cells—similar to oil in water—appears to closely control the activity of this protein.

ASU study reveals how diets high in saturated fats cause colon cancer

For decades, physicians and dieticians have urged people to limit their intake of high fat foods, citing links to poor health outcomes and some of the leading causes of death in the U.S., such as diabetes, heart disease and cancer.

Commonly used antidepressant drugs can also help the immune system to attack cancer

A class of drug called monoamine oxidase inhibitors is commonly prescribed to treat depression; the medications work by boosting levels of serotonin, the brain's "happiness hormone."

Study reveals key molecule involved in myelin repair

New research works indicate that new brain cells are continuously formed in response to physical exercise, injury, and mental stimulation.

Pre-trained viruses are more effective in countering antibiotic resistance

The risk of antibiotic resistance increases as bacteria continue to evade even the most powerful contemporary medicinal treatments. Antibiotic-resistant microorganisms threaten to take more than 10 million lives by 2050, as present-day treatments prove ineffective.

NIH grant awarded to model and analyze protein-ligand interactions in cancer research

Computer scientist Lydia Kavraki of Rice University's Brown School of Engineering has won a prestigious National Institutes of Health U01 grant to develop a new approach to model and analyze protein-ligand interactions in cancer research.

Single biomarker in the blood can accurately indicate underlying neurodegeneration

Levels of a protein called neurofilament light chain (NfL) in the blood can identify those who might have neurodegenerative diseases such as Down's syndrome dementia, motor neuron disease (ALS) and frontotemporal dementia, when clinical symptoms are not definitive.

Study shows how immune cells organize themselves in the epidermis

The human skin is essentially an organ, a fact that that is easy to forget. It is also the largest organ and is continuously exposed, charged with keeping the human inner biology safe from the threats of the outside world.

New insights on how synovial sarcoma develops and spreads

A new study published today in Cancer Discovery, a journal of the American Association for Cancer Research, reports findings that may change the understanding of how synovial sarcoma develops and spreads.

Immune therapy after surgery reduces recurrence risk in patients with high-risk melanoma

Patients with high-risk melanoma who had a course of pembrolizumab after their surgery had a longer time before their disease recurred than patients who got either ipilimumab or high-dose interferon after surgery. These findings of a large SWOG Cancer Research Network clinical trial, S1404, will be presented at the ASCO annual meeting June 6, 2021.
