Food For Thought: Cells Dine On Their Own Brains To Stay Fit And Trim
Eating your own brain may not sound like a sensible approach to prolonging your life, but researchers have discovered that some single-celled organisms essentially do just that to keep themselves healthy.
Cells In Retina Found To Behave Like Soap Bubbles
Soap bubbles delight children and the young at heart, but they also have been objects of scientific study for centuries.
Heart Attack In A Laboratory Dish
NWO researchers at Utrecht University have given heart muscle cells a heart attack in the laboratory.
How Cell Suicide Protects Plants From Infection
Researchers at Yale have identified a gene that regulates the major immune response in plants, programmed cell death (PCD), according to a recent report in the journal Cell.
Why Don't All Moles Progress To Melanoma?
Sometimes pigment-producing cells in moles called melanocytes start dividing abnormally to form a deadly form of skin cancer called melanoma.
Peripheral Timekeeping: Mammalian Cells Outside The Brain Have Their Own Circadian Clocks
Researchers have discovered that individual fibroblast cells contain independent, self-sustaining circadian (ca. 24 hr) clocks.
UT Southwestern Researchers Decode Filament Structures That Help Organize Signaling Molecules In Cells
Scientists have found the blueprint for how filaments assemble during the development of caveolae, a membrane system that organizes signaling molecules used by cells to communicate with each other.
Study Identifies Key Step Allowing Cells To Migrate
University of North Carolina at Chapel Hill researchers have discovered a prime regulator of the mechanism by which human cells migrate in health and in illness, a process crucial to sustaining life.
Minnesota Researchers Identify Protein That Causes Cell Nucleoli To Disassemble
Researchers at the University of Minnesota have identified the protein responsible for disassembly of donor nucleoli in the context of nuclear cloning.
How The Cell Finds Its Center
Yeast cells place their nucleus in the center of the cell, where the nucleus helps define where the cell will later divide in half.
How To Mend A Broken Heart: Zebrafish Hold Key To Regeneration
When a portion of a zebrafish's heart is removed, the dynamic interplay between a mass of stem cells that forms in the wound and the protective cell layer that covers the wound spurs the regeneration of functional new heart tissue...
Chromatin, Not Proteins, Support Chromosomes During Cell Division
When cells divide and transfer copies of genes to daughter cells, the process includes a phase where the replicated chromosomes are tightly condensed into durable packages called mitotic chromosomes.
The return of the peroxisome
Highlighted several new developments in the peroxisome field, including advances in our understanding of their partitioning during cell division, the role of the PTS1 receptor in import of proteins into the organelle and the formation of new peroxisomes f
Origin and evolution of the peroxisomal proteome
Findings in this study indicate that the peroxisome does not have an endosymbiotic origin and that its proteins were recruited from pools existing within the primitive eukaryote.
The shape of life: research sheds light on how cells take shape
This phenomenon of pattern formation is critical in developmental biology. But the forces that govern it are far from clear.
Loosen up, DNA: Leukemia gene changes genetic packaging
While the research involving a cellular signaling system known as JAK/STAT focused on complex questions involving the roots of cancer, the answers the researchers got came very simply and clearly – in red and white.
No cell walls, no new cancer cells
As with a house, the cell wall needs to be built at just the right moment to protect and allow the construction of internal components. A team from the Uppsala Branch of the global Ludwig Institute for Cancer Research (LICR) has not only shown how the cel
Researchers discover communication signal for tissue development
The finding provides new information about how cells and tissues determine when to let go from surfaces during new growth, according to the researchers.
Beyond lipids: understanding the mechanics of atherosclerosis
Atherosclerotic narrowing and hardening of coronary arteries typically appear first at vessel branches, and a study in the October issue of Cellular Signalling reports that the type of mechanical stretching found at those branches activates a cellular pro
New angiogenesis finding may help fight cancer growth
A researcher has discovered a new part of the complicated mechanism that governs the formation of blood vessels, or angiogenesis.
