Mutant Vimentin Promotes Aggressive Breast Cancer Growth

Vimentin is a type III intermediate filament (IF) protein typically expressed in cells that differentiate into connective tissue, blood vessels, and lymphatic tissue (mesenchymal cells).

Segmented Nerve Cords Enable Precision and Flexibility in Cephalopod Arms

Findings on cephalopod nerve cords highlight segmentation's role in sucker movement control, advancing knowledge of neural architectures in soft-bodied species.

Study Reveals Key Ion Channel in Extracellular Vesicles for Cargo Transport

Scientists have revealed the secret to the structural integrity of tiny particles that transport cargo from cell to cell through blood vessels and bodily fluids: special proteins that keep their membranes intact as they negotiate shifting electrical impulses in different biological environments.

Epigenetic Mechanism Controls Placental Blood Vessel Formation

If the development of blood vessels in the placenta is impaired, fetal growth retardation may result. Scientists from the German Cancer Research Center (DKFZ) and the Mannheim Medical Faculty of Heidelberg University discovered that the correct development of functioning blood vessels in the mouse placenta is controlled epigenetically: One of the enzymes that modify gene activity using methyl groups is responsible.

Research Shows How Sleep Clears Brain Waste

A good night's sleep does more than just help you feel rested-it might literally clear your mind. A new study published January 8 in the Cell Press journal Cell shows how deep sleep may wash away waste buildup in the brain during waking hours, an essential process for maintaining brain health.

Bioengineered Vessels Offer Alternative to Synthetic Grafts for Vascular Repairs

A new type of bioengineered blood vessel showed strong results in treating severe vascular injuries, potentially offering vascular surgeons a better alternative to synthetic grafts when patients' veins aren't suitable for use in repairs.

Key Enzymes Identified as Regulators of Cancer Cell Nutrient Foraging

Cancer cells are like booming cities without urban planners. They expand quickly, and in doing so, the resulting tumors consume more energy and other resources than they can acquire from nearby blood vessels.

Study Reveals Key Role of Interleukin-38 in Skin Renewal

The mechanisms underlying skin renewal are still poorly understood. Interleukin-38 (IL-38), a protein involved in regulating inflammatory responses, could be a game changer.

Study Links Extracellular Vesicles to Blood Vessel Damage in Cancer

A landmark study led by WEHI and La Trobe University has found a potential new diagnostic marker that could be used to better detect the level of tissue damage in our bodies.

Researchers Identify Mechanism of Immune Suppression in Ovarian Cancer

Researchers at Weill Cornell Medicine have shown that ovarian cancers disable immune cells and prevent them from attacking by cutting off the energy source that T cells rely on.

Human Skin Map Gives ‘Recipe’ to Build Skin and Could Help Prevent Scarring

For the first time, researchers have created a single cell atlas of prenatal human skin to understand how skin forms, and what goes wrong in disease.

Single-Cell Sequencing Reveals Mechanism of Coronary Artery Formation

The process by which new arteries develop in the heart has been clarified by a group under the direction of Dr. Elena Cano at the Integrative Vascular Biology Lab of Professor Holger Gerhardt at the Max Delbrück Center in Berlin.

Breakthrough Research Reveals Early Development of Eye Macrophages in Mice

Macrophages, also known as scavenger cells, are part of our immune system. They destroy invading pathogens and are found in the organs and the bloodstream.

Noninvasive Ultrasound Method Enables Tracking of Gene Expression in Specific Brain Regions

The ability to alter or prevent the expression of faulty genes in the brain could be leveraged as a powerful therapeutic against neurodegenerative disease. However, the molecular underpinnings of the living brain are still largely inaccessible, hampering progress on such promising therapeutics.
