Small protein has a large impact on bacterial gene regulation

Meningococci are bacteria that can cause life-threatening meningitis and sepsis. These pathogens use a small protein with a large impact: The RNA-binding protein ProQ is involved in the activation of more than 250 bacterial genes.

Using advanced microscopy techniques to see single molecules of telomerase in living cells

Canadian scientists have achieved a first in the study of telomerase, an essential enzyme implicated in aging and cancer.

Scientists uncover why developing nerve cells take a wrong turn

A group of scientists from CECAD, the Cluster of Excellence 'Cellular Stress Responses in Aging-Associated Diseases,' have found a mechanism by which neurodevelopmental diseases concerning neurons can be explained: The loss of a certain enzyme, UBE2K, impeded the differentiation of stem cells by silencing the expression of genes important for neuronal differentiation and, therefore, the development and generation of neurons.

Bacteria lurking in cancer cells may affect treatment

Cancer cells are comfy havens for bacteria. That conclusion arises from a rigorous study of over 1,000 tumor samples of different human cancers.

New advance addresses a big challenge with using CRISPR in cancer patients

A mutation unique to certain cancer tumors is a potential homing beacon for safely deploying CRISPR gene editing enzymes to disarm DNA that makes cancer cells resistant to treatment, while ignoring the gene in normal cells where it's critical to healthy function, according to a new study from ChristianaCare's Gene Editing Institute in the journal Molecular Cancer Research.

Study resolves contradictions surrounding p53 gene's role in pluripotent stem cell differentiation

The gene p53 is extremely important in cell biology and, hence, the world of cell replacement therapy. Its role is to regulate the cell cycle and halt the formation of tumors, leading to its nickname the "tumor suppressor gene."

Stem cell model sheds new light on the devastating process of neurodegeneration

A new study published today in Neuron led by The New York Stem Cell Foundation Research Institute's Valentina Fossati, Ph.D., creates astrocytes - an integral support cell in the brain - from stem cells and shows that in disease-like environments, these normally helpful cells can turn into neuron-killers.

UTA cancer researcher establishes new lab with CPRIT award

With $2 million in support from the Cancer Prevention & Research Institute of Texas, The University of Texas at Arlington has added an emerging leader in cancer biology to its faculty and fortified its cancer research enterprise.

Study sheds light on homologous recombination of DNA strands

As chromosomes go, X and Y make an unlikely pair. The X is large and contains thousands of genes critical for life. The Y, by contrast, is little more than a nub.

Biophysicists reveal molecular mechanism behind light-driven sodium pumping

An international research team has for the first time obtained the structure of the light-sensitive sodium-pumping KR2 protein in its active state.

Researchers grow lung organoids from stem cells for Sars-Cov-2 research

A Bochum-based team intends to use organoids from stem cells to study the progression of Sars-CoV-2 infection and to identify antiviral substances.

Two marine molecules show potential to treat Alzheimer's disease

An interdisciplinary research study of the University of Barcelona identified two potential candidates to treat Alzheimer's disease. These are two marine molecules, meridianine and lignarenone B, able to alter the activity of GSK3B activity, a protein associated with several neurodegenerative diseases.

New insight into RNA movements can pave way for strategies to treat cancer

Research from Karolinska Institutet published today in Nature shows that an RNA molecule involved in preventing tumour formation can change its structure and thereby control protein production in the cell.

Study offers new insight into how cells fuse

Scientists have known for a decade that cells that fuse with others to perform their essential functions - such as muscle cells that join together to make fibers - form long projections that invade the territory of their fusion partners.

Study uncovers how protein inhibits the development of tumors in mice

Proteins are found throughout our cells and regulate a lot of biological processes that are important forour survival.

Collagen maturation regulates PEDF availability, study shows

Cells are like tiny self-contained machines that are constantly fine-tuned in response to both internal and external signals. Some of these signals are induced by extracellular ligands, specialized proteins that bind to specific receptors on the cell surface, stimulating signaling pathways and altering gene expression.
