Penn Engineers Show Key Feature for Modeling How Cells Spread in Fibrous Environments
Penn Engineers Cells Spread Fibrous Environments
2017/7/20
One area of research within mechanobiology, the study of how physical forces influence biological processes, is on the interplay between cells and their environment and how it impacts their ability to...
New Tool Illuminates Cell Signaling Pathways Key to Disease
Cell Signaling Pathways Key Disease
2017/4/27
In a major advance for fundamental biological research, UC San Francisco scientists have developed a tool capable of illuminating previously inscrutable cellular signaling networks that play a wide va...
Flexibility is key in mechanism of biological self-assembly
Flexibility key in mechanism biological self-assembly
2017/3/30
A new study has modeled a crucial first step in the self-assembly of cellular structures such as drug receptors and other protein complexes, and found that the flexibility of the structures has a dram...
Nobody likes a cheater. In a recent study, a University of Houston evolutionary biologist and her collaborators found that while cheaters do not take over populations, they also cannot ever fully be r...
SCIENTISTS IDENTIFY FIRST NUTRIENT SENSOR IN KEY GROWTH-REGULATING METABOLIC PATHWAY（图）
SCIENTISTS FIRST NUTRIENT SENSOR GROWTH-REGULATING METABOLIC
2015/1/20
CAMBRIDGE, Mass.– Known as much for its complexity as its vital role in regulating cellular and organismal growth, the mechanistic target of rapamycin complex 1 (mTORC1) pathway has seemingly been act...
Overlapping and distinct functions for Gli proteins: Key mediators of hedgehog signaling in cell specification during embryonic development
Signals embryonic tissue cell differentiation the central nervous system the pituitary gland the pancreas cells
2014/12/11
Hedgehog (Hh) signaling is important for patterning and cell differentiation within many embryonic tissues. Hh is expressed in the notochord and the floor plate and acts as a morphogen in patterning o...
“Recent research has found that cancer is already adept at using cyberwarfare against the immune system, and we studied the interplay between cancer and the immune system to see how we might turn the ...
Wisconsin researchers identify key pathway for plant cell growth（图）
plant cell key pathway
2014/3/18
For plants, the only way to grow is for cells to expand. Unlike animals, cell division in plants happens only within a tiny region of the root and stem apex, making cell expansion the critical path to...
Researchers had known for several decades that a certain chemical modification exists on messenger ribonucleic acid (mRNA), which is essential to the flow of genetic information. But only recently did...
