This symposium discussion of the Loyola Los Angeles Law Review focuses on newly enacted California Consumer Privacy Act (CPPA), a statute signed into state law by then-Governor Jerry Brown June 28, 2018 and effective as January 1, 2020. The panel was held February 20, The panelists discuss how businesses are responding to new obstacles for consumers make use law’s protections rights. Most i...

Many Gram-positive pathogens link the expression of virulence genes to the presence of carbon source substrates using overlapping pathways for global control of carbon catabolite regulation. However, how these pathways are integrated to control the behavior of the transcriptome in time- and compartment-specific patterns is typically not well understood. In the present study, global transcriptom...

Carbon catabolite repression (CCR) is one of the most fundamental environmental-sensing mechanisms in bacteria and imparts competitive advantage by establishing priorities in carbon metabolism. In gram-positive bacteria, the master transcription regulator of CCR is CcpA. CcpA is a LacI-GalR family member that employs, as an allosteric corepressor, the phosphoprotein HPr-Ser46-P, which is formed...

Biofilm formation in Staphylococcus aureus under in vitro growth conditions is generally promoted by high concentrations of sugar and/or salts. The addition of glucose to routinely used complex growth media triggered biofilm formation in S. aureus strain SA113. Deletion of ccpA, coding for the catabolite control protein A (CcpA), which regulates gene expression in response to the carbon source,...

Catabolite control protein A (CcpA) is the master regulator in Gram-positive bacteria that mediates carbon catabolite repression (CCR) and carbon catabolite activation (CCA), two fundamental regulatory mechanisms that enable competitive advantages in carbon catabolism. It is generally regarded that CcpA exerts its regulatory role by binding to a typical 14- to 16-nucleotide (nt) consensus site ...

OBJECTIVES Antibiotic tolerance is a phenomenon allowing bacteria to withstand drug-induced killing. Here, we studied a penicillin-tolerant mutant of Streptococcus gordonii (Tol1), which was shown to be deregulated in the expression of the arginine deiminase operon (arc). arc was not directly responsible for tolerance, but is controlled by the global regulator CcpA. Therefore, we sought whether...

In the heart, endogenous adenosine attenuates the β-adrenergic-elicited increase in contractile performance via activation of adenosine A1 receptors. It has been recently reported that this function of adenosine becomes more pronounced with myocardial maturation. The purpose of the present study was to determine whether mature hearts possess a greater sensitivity than immature hearts to this an...

The mechanism by which distinct stimuli activate the same mitogen-activated protein kinases (MAPKs) is unclear. We examined compartmentalized MAPK signaling and altered redox state as possible mechanisms. Adult rat cardiomyocytes were exposed to the adenosine A(1) receptor agonist 2-chloro-N(6)-cyclopentyladenosine (CCPA; 500 nM) or H(2)O(2) (100 microM) for 15 min. Nuclear/myofilament, cytosol...
