Continued Folic Acid Supplementation Throughout Pregnancy, May Cause Colorectal Cancer In The Future
An article about folic acid supplementation during pregnancy may lead to colorectal cancer as recent studies found
'Natural Killer' Cells Keep Immune System In Balance
Researchers from Brown University and McGill University have discovered that the natural killer, or NK cells, help prevent T cells from over-responding when a virus hits.
New Concoction Reprograms Differentiated Cells Into Pluripotent Stem Cells
Scientists report that a novel transcription factor can replace one of the classical reprogramming factors, Oct4, to significantly increase the efficiency of reprogramming differentiated stem cells into induced pluripotent stem cells.
Taking The Conversation Inside: Enhancing Signals In Cell Interior
Scientists used to think most of the exchange of information between cells was conducted at the surface, where cell receptors receive signals from other cells.
New Technique Allows Scientists To Penetrate Yeast Cells' Hard Exterior
If you want to know how a cell responds to a particular chemical, the experiment is simple: Inject it with that chemical.
New Way To Distinguish Cancerous From Normal Cells
Researchers has discovered a previously unknown feature that distinguishes cancer from normal cells: the difference in cell surface properties.
Researchers Examine Mechanisms That Help Cancer Cells Proliferate
A process that limits the number of times a cell divides works much differently than had been thought, opening the door to potential new anticancer therapies
Cells Send Dirty Laundry Home to Mom
Understanding how aged and damaged mother cells manage to form new and undamaged daughter cells is one of the toughest riddles of ageing, but scientists now know how yeast cells do it.
Newly Discovered Mechanism Allows Cells to Change State
Cells are not static. They can transform themselves over time -- but change can have dangerous implications.
How An Enzyme Tells Stem Cells Which Way To Divide
Driving Miranda, a protein in fruit flies crucial to switch a stem cell's fate, is not as complex as biologists thought, according to University of Oregon biochemists.
Cancer Research: New Data On The Breakdown Of The KRas Protein
KRas is one of the usual suspects in cancer.
The History, Biochemistry, and Potential of Quorum Sensing
Bacteria have always been considered to act independently of a population. Until recently, cell-to-cell communication was never thought plausible in simple prokaryotes.
“Artificial Golgi” may provide new insight into key cell structure
Scientists in New York and North Carolina are reporting assembly of the first functioning prototype of an artificial Golgi organelle.
Protein Forces & Structure - Bonds Stabilizing the Folded 3D Conformation
This article discusses the peptide bond in the primary amino acid structure, secondary structure as the alpha helix and the beta pleated sheet and tertiary structure involving ionic bonds, hydrogen bonds and hydrophilic & hydrophobic interactions.
Concise Review: Multipotent Mesenchymal Stromal Cells in Blood
In this review, current studies/knowledge about peripheral blood-derived multipotent mesenchymal stromal cells is summarized, and the above-mentioned topics are discussed.
Researchers Further Unravel The Mystery Of Cell Death
Cells die. It's a normal part of development and of aging.
Proteins Strangle Cell During Division
A Swedish research group has discovered a new mechanism for cell division in a microorganism found in extremely hot and acidic conditions.
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.
Molecular Code Broken For Drug Industry's Pet Proteins
All cells are surrounded by protective, fatty membranes.
Cellular Symmetry: What Cues Tell A Cell To Divide At The Center
Cells are intrinsically artistic. When the right signals tell a cell to divide, it usually splits down the middle, resulting in two identical daughter cells.
