The field of metabolic engineering has yielded remarkable accomplishments in using cells to produce valuable molecules, and cell-free expression (CFE) systems have the potential to push the field even further. However, CFE systems still face some outstanding challenges, including endogenous metaboli...
Biotechnology has transformed the production of various chemicals and pharmaceuticals due to its efficient and selective processes, but it is inherently limited by its use of live cells as 'biocatalysts.' Cell-free expression (CFE) systems, which use a protein lysate isolated from whole cells, have ...
This study characterized functions and metabolic profiles of cell-free supernatants (CFS) from Lactobacillus johnsonii KD1 against three foodborne pathogens: the Gram-negative bacteria Vibrio parahaemolyticus 3HP and Salmonella enterica serovar ...
Mycelia of Diaporthe nobilis(50 mg) treated with CFS were collected,Each sample was homogenized in 400 µL of pre-cooled 80% methanol aqueous solution containing 0.02 mg/mL L-2-chlorophenylalanine (internal standard). The mixture was ground and subjected to ultrasonication at 4 °C for 30 min. Afte...
We explored the transcriptional response of Faecalibacterium prausnitzii A2-165 when exposed to cell-free supernatants from different Lactobacillus, Streptococcus and Lactococcus strains. For that, we sequenced its RNA and looked for significant differences in the expression levels among the superna...
Oral eubiosis is of utmost importance for local and systemic health. Consolidated habits, as excessive alcohol consumption, smoke, inappropriate oral hygiene, and western diet, exert detrimental effects on oral microbiota composition and function. This leads to caries, gingivitis, and periodontitis,...

The human lung cancer cell line A549 was cultured in media alone, with cyclophosphamide (CPM) or oxaliplatin (OXP) for 72 hours. The exhausted culture media were aspirated and the microvesicular fraction was harvested by sequential ultracentrifugation. RNA was then isolated from microvesicles by Tr...
