a.Shivering : there will be more skeleton muscle contraction, which require more respiration to provide ATP, while more heat energy can be produced b.Increased level of thyoxine and adrenaline : this two hormone is associated with incrase cell metabolism , including increase the breakdown of glyco...
We also identified various cell types in the gills of the West African lungfish (selected marker genes are shown in Supplementary Fig.1d). The number of immune cells in the gill (under freshwater and terrestrialization conditions) is more than that of the lungs, likely because that its externa...

we identify various cell-specificcis-regulatory elements and construct organ-specific gene regulatory networks at the single-cell level. Finally, we perform comparative analyses of single-cell landscapes among mouse, monkey and human. We show that cynomolgus monkey has strikingly higher degree of simila...
3a. The cytoplasm is treated as the 1st-level hierarchy, which fills the entire cell. A single MT can be discretized into an infinite series of springs with elastic stiffness E2, with each node connected to the cytoplasm (the 1st-level structure). Then, each MT embedded into the cytoplasm...
