Project description:Our transcriptome data shows that the two-component system CesSR, which senses cell envelope stresses of different origins, is one of the major players when L. lactis is forced to overproduce the endogenous membrane protein BcaP, a branched-chain amino acid permease. Two-condition experiment: nisin induced overproduction of BcaP vs. control. Biological replicates: 2 controls, 2 overproduction cultures; independently grown and harvested; dye swaped on the second array.
Project description:MCF12A monolayer cultures were exposed to ethanol or acetaldehyde for eiher 1 week or 4 weeks Total RNA samples were assayed for gene expression and for microRNA expression. MicroRNA expression was accomplished using 2 experiments. The first experiment included untreated control, ethanol treated (4 weeks at 2.5 mM) and acetaldehyde treated (4 weeks at 1 mM). The data are presented in order of control1 for the ethanol and acetaldehyde treated samples followed by the ethanol and acetaldehyde treated samples, and then the control2 for the soft agar selected sample followed by the soft agar selected sample. The microRNA names are included in separate columns.

Project description:L. lactis was grown in steady-state cultures at specific growth rate 0.2 h-1. The concentration of L-threonine in the growth environment was smoothly increased from 1.24mM to 4mM and proteome measurements were carried out to detect proteins involved in threonine metabolism.
