Project description:Modulation of gut microbiota through probiotic supplementation is an interesting strategy to prevent obesity We use microarrays to study the global genome expression of C. elegans fed with the probiotic strain Bifidobacterium animalis sbsp. lactis CECT 8145 Wild type strain N2 of C. elegans was cutured in Nematode Growth medium (NGM, control fed) or NGM with a bacterial lawn fed of the strain B. animalis subsp. lactis CECT 8145, until reach young adult stage. Worm population were age-synchronized. RNA was isolated from each populations (control and treated) using RNAasy Kit (Qiagen) and hybridizated on Affymetrix microarrays.
Project description:To study the effect of Radix Paeoniae Rubra decoction on tolerance of Staphylococcus aureus.The effect of Radix Paeoniae Rubra on the resistance of Staphylococcus aureus to oxacillin sodium was studied by millipore dilution method in this experiment.At the same time ,conducted on transcriptome analysis of Staphylococcus aureus related genes in Radix Paeoniae Rubra.And to detect the expression level of related genes of Staphylococcus aureus under the action of Radix Paeoniae Rubra by PCR technology.The tolerance of Staphylococcus aureus was decreased obviously when the concentration of Radix Paeoniae Rubra decoction was above 1mg/ml.The effect of Radix Paeoniae Rubra decoction on the expression of tolerance genes femB,pvL and gluM when the concentration of Radix Paeoniae Rubra decoction was above 4mg/ml.When rhe concentration of Radix Paeoniae Rubra is more than 1mg/ml,it can effectively reduce the resistance of Staphylococcus aureus to oxacillin sodium.The reason may be due to the effect of Radix Paeoniae Rubra on the resistance gene of Staphylococcus aureus.
Project description:Transcriptomic study to characterize the functional role of AfpB and its interaction with the producer fungus P. digitatum. For this, the transcriptome of P. digitatum PHI26 strain (CECT 20796) was compared with samples treated with AfpB and an AfpB overproducing strain.
Project description:The goal was to determine the effect of agmatine on the trancriptional profile of L. lactis CECT 8666 strain. For that we compared the expression profile of L. lactis CECT 8666 cells grown in culture medium supplemented with 20 mM agmatine with the expression profile of L. lactis CECT 8666 cells grown in culture medium without agmatine.

L. lactis CECT 8666 cells grown in GalM17 medium (reference) compared to L. lactis CECT 8666 cells grown in GalM17 medium supplemented with 20 mM agmatine (test).
