Project description:Lactobacillus casei Zhang is a probiotic bacterium isolated from koumiss in Inner Mongolia of China. Gene expression dynamics of L. casei Zhang during growth in soymilk was investigated in attempt to reveal the mechanisms involved in growth stimulation for growing probiotics in. Comparison of different transcripts next to each other revealed 162 and 63 significantly induced genes in late logarithmic phase and stationary phase, of which the expression was at least 3 fold up-regulated and down-regulated, respectively. Approximately, 38.4% of the up-regulated genes were associated with amino acid transport and metabolism notably for histidine and lysine biosynthesis, followed by genes/gene clusters involved in carbohydrate transport and metabolism, lipid transport and metabolism, and inorganic ion transport and metabolism. The analysis results suggest that the stimulatory effect of soymilk-based ecosystem on the L. casei Zhang growth is more complex than amino acids or oligopeptides supply.

Effect of probiotic Lactobacillus casei Zhang on liver gene expression of hypercholesterolemic rats

Project description:The hypocholesterolemic effect of probiotics has been observed, but the molecular mechanism of probiotic-host interaction is still obscure. In this study, DNA microarray technology was used to explore the gene expression profile of liver of hypercholesterolemic rats caused by administration of probiotic Lactobacillus casei Zhang, which can decrease the serum triglyceride, low-density lipoprotein cholesterol, hepatic cholesterol and triglyceride of hypercholesterolemic rats.
