In Smad pathway, by using cyclohexamide and proteosome inhibitor MG132, we showed that BMP-2 significantly increased inhibitory Smad ( i.e., Smad7) and down-regulated the half-life and protein levels of TbetaRI by poly-ubiquitination and proteosomal degradation.

Relative contents of four main cellular proteins corresponding to MALDI-TOF-MS peaks m/z 4466, m/z 6455, m/z 6514, and m/z 7772 were all found to be close correlated with the concentration of melamine, although their up- and/or down-regulations showed different patterns when the concentration of melamine changed. Support vector regression leave-one-out method, with the optimized polynomial kernel function and a poly-degree of 3, was chose to evaluate the correlation between the alteration of Tetrahymena pyriformis main proteins'relative contents and the concentration of melamine in the culture medium.

The results showed that there was a more better effect of filmformation and absorbency to use poly 1788 as an adhesive and polyvinyl pyrrolidone(K:90) as a hydrophilic polymer. The silicon dioxide with particle size 0.3-1 μm as a inorganic pigment had a better absorbency. The polyethylene glycol modified with ethylenediamine had a more better characteristic of dye immobilization, absorbency and definition than the polyethylene glycol modified with diethylenetriamine, of which the polyethylene glycol of molecular weight of 400 modifiedwith ethylenediamine had more best performance.
