Autor: Barbara Ramos, Daniel González-Acuña, David E. Loyola, Warren E. Johnson, Patricia G. Parker, Melanie Massaro, Gisele P. M. Dantas, Marcelo D. Miranda, Juliana A. Vianna

Publikováno v: BMC Genomics, Vol 19, Iss 1, Pp 1-17 (2018)

Abstract Background Mitochondria play a key role in the balance of energy and heat production, and therefore the mitochondrial genome is under natural selection by environmental temperature and food availability, since starvation can generate more ef

Autor: Daniel Castillo, Diliana Pérez-Reytor, Nicolás Plaza, Sebastián Ramírez-Araya, Carlos J. Blondel, Gino Corsini, Roberto Bastías, David E. Loyola, Víctor Jaña, Leonardo Pavez, Katherine García

Publikováno v: Frontiers in Microbiology, Vol 9 (2018)

Vibrio parahaemolyticus is the leading cause of seafood-borne gastroenteritis worldwide. As reported in other countries, after the rise and fall of the pandemic strain in Chile, other post-pandemic strains have been associated with clinical cases, in

Conservation of Small Regulatory RNAs in Vibrio parahaemolyticus: Possible role of RNA-OUT Encoded by the Pathogenicity Island (VPaI-7) of Pandemic Strains

Autor: Nicolás Plaza, Diliana Pérez-Reytor, Sebastián Ramírez-Araya, Alequis Pavón, Gino Corsini, David E. Loyola, Víctor Jaña, Leonardo Pavéz, Paola Navarrete, Roberto Bastías, Daniel Castillo, Katherine García

Publikováno v: International Journal of Molecular Sciences, Vol 20, Iss 11, p 2827 (2019)

Small regulatory RNAs (sRNAs) are molecules that play an important role in the regulation of gene expression. sRNAs in bacteria can affect important processes, such as metabolism and virulence. Previous studies showed a significant role of sRNAs in t

Comparative genome-wide polymorphic microsatellite markers in Antarctic penguins through next generation sequencing

Autor: Juliana A. Vianna, Daly Noll, Isidora Mura-Jornet, Paulina Valenzuela-Guerra, Daniel González-Acuña, Cristell Navarro, David E. Loyola, Gisele P. M. Dantas

Publikováno v: Genetics and Molecular Biology, Vol 40, Iss 3, Pp 676-687

Abstract Microsatellites are valuable molecular markers for evolutionary and ecological studies. Next generation sequencing is responsible for the increasing number of microsatellites for non-model species. Penguins of the Pygoscelis genus are compri

DNA, cell wall and general oxidative damage underlie the tellurite/cefotaxime synergistic effect in Escherichia coli.

Autor: Roberto C Molina-Quiroz, David E Loyola, Claudia M Muñoz-Villagrán, Raquel Quatrini, Claudio C Vásquez, José M Pérez-Donoso

Publikováno v: PLoS ONE, Vol 8, Iss 11, p e79499 (2013)

The constant emergence of antibiotic multi-resistant pathogens is a concern worldwide. An alternative for bacterial treatment using nM concentrations of tellurite was recently proposed to boost antibiotic-toxicity and a synergistic effect of tellurit

Scientific Reports, Vol 8, Iss 1, Pp 1-13 (2018)

How organisms adapt to unfavorable environmental conditions by means of plasticity or selection of favorable genetic variants is a central issue in evolutionary biology. In the Maipo River basin, the fish Basilichthys microlepidotus inhabits polluted

Genealogy of the Genome Components in the Highly Homogeneous Pandemic Vibrio parahaemolyticus Population

Autor: Romilio T. Espejo, David E. Loyola, Nicolas Plaza, Katherine García, Cristian Yáñez

Publikováno v: Journal of Phylogenetics & Evolutionary Biology.

Bacterial genomes evolve through two different mechanisms: 1) changes in or occasional loss of ancestral genes, which preserve the founder clonal genealogy or frame, and 2) sporadic gains of new genes via horizontal gene transfer, which introduces DN
