Cell cycle, the ordered sequence of events that occur in a cell in preparation for cell division. The cell cycle is a four-stage process in which the cell increases in size, copies its DNA, prepares to divide, and divides. Learn more about the cell cycle
A bile acid is any of a group of substances derived from cholesterol that play essential roles in the digestion and absorption of dietary fats and fat-soluble vitamins.
Nevertheless, body composition may differ between species and change during the life cycle of an individual. If required, MGM can describe effects of changes in body composition. Increased energy density of newly synthesized biomass EM (e.g. as a result of maturation that involves synthesis of ...
You perhaps already understand that **cell division**, in the majority of contexts that term is used, refers simply to a process of duplication: start with one cell, allow time for the growth of whatever is important in each cell, split the cell in half, and you now have double the nu...

using NMR spectroscopy and isothermal titration calorimetry, we map a region of the phosphoprotein, comprising residues between 110 and 140 and common to the V and W proteins, that binds with weak affinity to STAT1 and confirm the involvement of key amino acids of the viral protein in this int...
Acid invertase in Nicotiana tabacum crown-gall cells: Molecular properties of the cell-wall isoform Cell-wall invertase (CWI; EC 3.2.1.26) was salteluted from non-disrupted Agrobacterium tumefaciens-transformed Nicotiana tabacum L. cells and purified to h... M Weil,T Rausch - 《Planta》 被引...
However, it has also been noted that this increase in light intensity leads to a decrease in fucoxanthin production [87]. Light intensity exceeding 150 μmol photons m−2 s−1 has been found to induce the synthesis of photoprotective pigments, namely diadinoxanthin and diatoxanthin [88]....
Hypoxia has an important role in tumor progression via the up-regulation of growth factors and cellular adaptation genes. These changes promote cell survival, proliferation, invasion, metastasis, angiogenesis, and energy metabolism in favor of cancer development. Hypoxia also plays a central role in ...
Elastin functions in partnership with collagen, and endows vascular tissue with elasticity. Elastin synthesis normally ceases soon after puberty once the body reaches maturity. While elastin is extremely insoluble and stable with half-life times in the order of tens of years [14], it may be ...
