Signal Disruption Leads to Changes in Bacterial Community Population

Frontiers in Microbiology, 2019
The disruption of bacterial signaling (quorum quenching) has been proven to be an innovative approach to influence the behavior of bacteria. In particular, lactonase enzymes that are capable of hydrolyzing the N-acyl homoserine lactone (AHL) molecules ...

Expression of paraoxonase 1 in HEK293 cells and its effect on lactonase and arylesterase activity in samples containing human serum and/or prooxidant or antioxidant agents - a preliminary study [PDF]

Acta Poloniae Pharmaceutica, 2023
Expression of recombinant paraoxonase 1 (PON1) in the human embryonic kidney (HEK293F) cell line was evaluated. Two recombinant human PON1 proteins were investigated: PON1-Fc, which has an Fc-tag on its C-terminal, and His-PON1-Fc, which has an Fc-tag on

Modulation of paraoxonase 1 and 3 expression after moderate exercise training in the rat

Journal of Lipid Research, 2009
Paraoxonases (PONs) are a small family of antioxidant enzymes whose antiatherogenic activity is well known. The aim of the present study was the evaluation of the effects of moderate aerobic training on their expression using a rat model.

High yield expression of an AHL-lactonase from Bacillus sp. B546 in Pichia pastoris and its application to reduce Aeromonas hydrophila mortality in aquaculture

Microbial Cell Factories, 2010
Background Aeromonas hydrophila is a serious pathogen and can cause hemorrhagic septicemia in fish. To control this disease, antibiotics and chemicals are widely used which can consequently result in "superbugs" and chemical accumulation in the food ...
