cell viability to mesenchymal stem cells. The nanofibrous aerogels were further functionalized by SNF-mediated biomineralization, showing their possible as a bone-mimicking scaffold. Our results show the possibility of natural nanostructured silks in the field of biomaterials and supply a feasible ...
The crowded interior of a living cell makes performing experiments on simpler in vitro systems attractive. Although these reveal interesting phenomena, their biological relevance can be questionable. A topical example is the phase separation of intrinsic
Proteins are a second type of intracellular organic molecule. These substances are made from chains of smaller molecules called amino acids, and they serve a variety of functions in the cell, both catalytic and structural. For example, proteins called enzymes convert cellular molecules (whether prote...
Thebest type of creatine works in a way that gives good energy to the cells. It starts when creatine gets produced in the body or is consumed from external sources and gets combined with a phosphate molecule, which leads to the formation of creatine phosphate. ...
Where indicated, cells were pretreated with 100 nM rapamycin or vehicle before infection. Seventy-two hours after infection, cell size was measured with a Coulter counter. (B) A knockdown of DEPTOR has similar effects on cells size as a TSC2 knockdown. p53 null MEFs were infected with shRNAs...
This enzyme prompts conformational activation of integrin αIIbβ3, a cell adhesion molecule important in platelet aggregation [4]. Phosphatidylinositol 3-kinase also activates the serine/threonine protein kinase B and Rap1b guanosine triphosphate binding proteins, which, in turn, amplify the ...
We find that Dynamin, a conserved regulator of endocytosis and the cytoskeleton, serves a key role in DA tubulogenesis. We demonstrate that Dynamin is required for distinct aspects of DA tubulogenesis: DA-tube closure, DA-tube-cell intercalation, and biased apical-luminal cell expansion. We ...
What we do know is that by three and a half billion years ago the highly complicated molecule DNA had emerged. DNA is the basis of all life on earth. It has a double helix structure, like a spiral staircase.// Passage 15 几千年来我们中国人一直视筷...
