Activating an Estrogen Receptor Can Stop Pancreatic Cancer Cells from Growing

Activating the G protein-coupled estrogen receptor (GPER) – a receptor found on the surface of many normal and cancer tissues – has been shown to stop pancreatic cancer from growing, but may also make tumors more visible to the immune system and thus more susceptible to modern immunotherapy. Researchers at […]

New Insights into Early Embryonic Development

Revealing the architecture of embryos at a crucial stage in development. The majority of pregnancies that fail do so at a very early developmental stage, before the pregnancy is even detectable by tests. This critical stage, occurring about a week after fertilization, is when an embryo implants itself into the […]

Sex, Genes and Vulnerability

Researchers pinpoint genes behind sex biases in autoimmune disorders, schizophrenia. Some diseases exhibit a clear sex bias, occurring more often, hitting harder or eliciting different symptoms in men or women. For instance, the autoimmune conditions lupus and Sjögren's syndrome affect nine times more women than men, while schizophrenia affects more […]

First roadmap of human skeletal muscle development created by UCLA scientists

Findings could lead to better methods for creating muscle cells from stem cells. An interdisciplinary team of researchers at the Eli and Edythe Broad Center for Regenerative Medicine and Stem Cell Research at UCLA has developed a first-of-its-kind roadmap of how human skeletal muscle develops, including the formation of muscle […]

Stem cells shown to delay their own death to aid healing

Already known for their shape-shifting abilities, stem cells can now add “death-defying” to their list of remarkable qualities. A new study shows how stem cells – which can contribute to creating many parts of the body, not just one organ or body part – are able to postpone their own […]

Unexpectedly potent protein droplets

Repeats of individual building blocks within proteins are the cause of many hereditary diseases, but how such repeats actually cause disease is still largely unknown. Researchers in Berlin investigated how repeat elongations lead to the disease synpolydactyly, and have found that the attractive forces between the mutated proteins cause them […]

Exercise Boosts Motor Skill Learning Via Changes in Brain’s Transmitters

Doctors have relentlessly impressed upon us the many benefits of exercise. Energy, mood, sleep and motor skills all improve with a regular fitness regimen that includes activities such as running. This has become of particular interest in the time of the COVID-19 pandemic. But what happens in the brain during […]

Nanostimulators boost stem cells for muscle repair

In regenerative medicine, an ideal treatment for patients whose muscles are damaged from lack of oxygen would be to invigorate them with an injection of their own stem cells. In a new study published in the journal ACS Nano, researchers at the University of Illinois at Urbana-Champaign demonstrated that “nanostimulators” […]

Molecule reduces multiple pathologies associated with Alzheimer’s disease

When tested in brain cells and in a mouse model of Alzheimer’s disease, a new compound significantly reduced the number of amyloid plaques in the brain, lessened brain inflammation and diminished other molecular markers of the disease. The researchers who developed the compound reported their findings in the journal ACS […]

Another Example of a Galactose-Conjugated Senolytic Prodrug

Killing cells is easy. Killing only the cells that you want to kill, while leaving all other cells untouched, is very much more challenging. The ability to do this is fundamental to much of the future of medicine, however. The aging body contains many cell populations that cause significant harm […]

Towards Ionomic Aging Clocks

The ionome is the elemental composition of a tissue, organ, or individual. This composition changes over the course of aging, and may do so in ways that allow the production of an aging clock, a measure of chronological or physiological age. This line of development adds to work on the well-known epigenetic clocks, proteomic […]

Resilience to ALS Due to Synaptic Safety Mechanism

A common feature of neurodegenerative diseases such as Alzheimer’s disease and amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease) is the progressive loss of synapses – the anatomical sites of communication between brain cells – throughout the brain and spinal cord. Typically, synapse loss becomes pervasive before the outward appearance […]
