A snapshot of extracellular DNA influence on Aspergillus biofilm
(Frontiers Research Foundation, 2014-05-30)
Extracellular DNA and lipoteichoic acids interact with exopolysaccharides in the extracellular matrix of Streptococcus mutans biofilms
(2017-10-21)
Streptococcus mutans-derived exopolysaccharides are virulence determinants in the matrix of biofilms that cause caries. Extracellular DNA (eDNA) and lipoteichoic acid (LTA) are found in cariogenic biofilms, but their ...
Streptococcus mutans-derived extracellular matrix in cariogenic oral biofilms
(Frontiers Research Foundation, 2015-02-13)
Biofilms are highly structured microbial communities that are enmeshed in a self-produced extracellular matrix. Within the complex oral microbiome, Streptococcus mutans is a major producer of extracellular polymeric ...
The role of extracellular nucleic acids in the immune system modulation of Rhodnius prolixus (Hemiptera: Reduviidae)
(Academic Press Inc Elsevier Science, 2020-04)
Extracellular traps (ETs) are extracellular nucleic acids associated with cytoplasmic proteins that may aid in the capture and killing of pathogens. To date, only a few insects were shown to display this kind of immune ...
Extracellular matrix influence in Streptococcus mutans gene expression in a cariogenic biofilm
(2018-04-01)
Caries etiology is biofilm–diet-dependent. Biofilms are highly dynamic and structured microbial communities enmeshed in a three-dimensional extracellular matrix. The study evaluated the expression dynamics of Streptococcus ...
Fragmentation of extracellular DNA by long-term exposure to radiation from uranium in aquatic environments
(ROYAL SOC CHEMISTRYCAMBRIDGE, 2012)
Persistent harmful scenarios associated with disposal of radioactive waste, high-background radiation areas and severe nuclear accidents are of great concern regarding consequences to both human health and the environment. ...
Intra- and extra-cellular DNA damage by harmine and 9-methyl-harmine
(Elsevier, 2014-01)
It is known that β-carbolines are able to produce photosensitized damage in cell-free DNA, but there is little information on their effects on cellular DNA. Therefore, we have analyzed the DNA damage produced by harmine ...
Intra- and extracellular DNA damage by harmine and 9-methyl-harmine
(Elsevier Science Sa, 2014-02-13)
It is known that b-carbolines are able to produce photosensitized damage in cell-free DNA, but there is little information on their effects on cellular DNA. Therefore, we have analyzed the DNA damage produced by harmine ...
Diversity and extracellular enzymatic activities of yeasts isolated from King George Island, the sub-Antarctic region
(2012)
Background: Antarctica has been successfully colonized by microorganisms despite presenting adverse conditions for life such as low temperatures, high solar radiation, low nutrient availability and dryness. Although these ...
Inactivation of genes TEC1 and EFG1 in Candida albicans influences extracellular matrix composition and biofilm morphology
(Taylor & Francis Ltd, 2017-10-17)
Background: Infections caused by Candida spp. have been associated with formation of a biofilm, i.e. a complex microstructure of cells adhering to a surface and embedded within an extracellular matrix (ECM). Methods: The ...
