Final volume of 2.5 ml and heated in boiling water for 5 min. After cooled on ice, the solution was used for Western blot analysis. Same amounts of sample aliquots (20 mg protein) were subjected to 10 SDS-PAGE (10 gradient gel) and were transferred to PVDF membranes (Millipore, MA, USA) overnight at 12 V using the Bio-Rad Transblot apparatus (CA, USA). The membranes were MedChemExpress AKT inhibitor 2 blocked in 5 fat-free milk in Tris-Tween buffered saline (TTBS; 20 mM Tris/150 mM NaCl, pH 7.5, and 0.1 Tween20) for 3 h and then incubated with ASCT2, B0AT1 or b-actin antibody (Table 2) at 4oC overnight with gentle rocking. After washing three times with TTBS, the membranes were incubated at room temperature for 2 h with horseradish peroxidase-linked secondary antibodies (Santa Cruz, CA, USA). The secondary antibody were used at dilutions of 1:3,000. Finally, the membranes were washed with TTBS, followed by development using Supersignal West Dura Extended Duration Substrate according to the manufacturer’s instructions (Pierce, Rockford, IL). The images were detected on chemiluminescence (Applygen Technologies Inc., Beijing, China). Multiple exposures of each Western blot were performed to ensure linearity of chemiluminescence signals. Western blots were quantified by measuring the intensity of correctly sized bands using AlphaImager 2200 software (Alpha Innotech Corporation, CA, USA). The ratio of intensities of a studied protein band and housekeeping protein band was calculated for each filter and the ratios from different 1662274 Western blot filters were used for analyzing the abundances of studied proteins.Table 3.

Compared with the HBW piglets, the liver contents of 12 measured NAA, excepting Cys, in the LBW piglets were higher (P,0.05) on day 0 of age, whereas LBW piglets had lower content of Cys on day 14 of age. No significant differences in liver contents of NAA Benzocaine cost between LBW and HBW piglets was observed on days 7 and 21 of age. The liver content of all measured NAA, excepting Cys, in piglets was increased (P,0.001) from days 0 to 21 of age. There were interaction effects between age and BW on liver content of all measured NAA in suckling Huanjiang mini-piglets (P,0.05).Statistical AnalysisThe data were analyzed by a mixed-effects model using the SAS version 9.2. The statistical model used included the main effects of BW size, age, and their interactions, age entered the model as a repeated measure with sow within BW class as a subject, and the individual sow was served as a random effect. Probability values ,0.05 were taken to indicate statistical significance.Muscle Contents of NAA in Huanjiang Mini-piglets with LBW or HBWThe muscle contents of 12 NAA in piglets with LBW or HBW from days 0 to 21 of age was examined.
