A Phylogenetic Approach to Structural Variation in Organization of Nuclear Group I Introns and Their Ribozymes

open access: yesNon-Coding RNA, 2021
Nuclear group I introns are restricted to the ribosomal DNA locus where they interrupt genes for small subunit and large subunit ribosomal RNAs at conserved sites in some eukaryotic microorganisms.

So near and yet so far: Harmonic radar reveals reduced homing ability of nosema infected honeybees [PDF]

open access: yes, 2014
Pathogens may gain a fitness advantage through manipulation of the behaviour of their hosts. Likewise, host behavioural changes can be a defence mechanism, counteracting the impact of pathogens on host fitness.

The Coevolution of Fungal Mitochondrial Introns and Their Homing Endonucleases (GIY-YIG and LAGLIDADG)

open access: yesGenome Biology and Evolution, 2020
Fungal mitochondrial (mt) genomes exhibit great diversity in size which is partially attributed to their variable intergenic regions and most importantly to the inclusion of introns within their genes.

Mariano Barbacid: Bringing cancer biology back home [PDF]

open access: yesCurrent Biology, 2000
After spending half of his life in the US, where he achieved considerable recognition as a discoverer of human oncogenes first and a researcher in molecular oncology afterwards, Spanish biologist Mariano Barbacid, now 50 years old, returned to Spain two years ago, full of hope and of plans for a first class research centre on oncology.

Multimodal in vivo imaging reveals limited allograft survival, intrapulmonary cell trapping and minimal evidence for ischemia-directed BMSC homing

open access: yesBMC Biotechnology, 2012
Background Despite positive reports on the efficacy of stem cell therapy for the treatment of cardiovascular disease, the nature of stem cell homing to ischemic tissues remains elusive. Results We used a mouse model of peripheral tissue ischemia to study

BIOMAP: A Home for All Biology Methods [PDF]

open access: yesBiology Methods and Protocols, 2016
The moments of rapid acceleration of scientific progress have different origins. Some occur due to conceptual advances, such as the description of evolution by natural selection or the development of relativity theory. Some occur due to technological advances, and in the case of Biology, the development of new methodologies has been and is a driving ...

Editorial: A home for virology, ecology, epidemiology, and evolutionary biology [PDF]

open access: yesVirus Evolution, 2015
Viruses make headline news on an almost daily basis. Sometimes the news is positive, a report on the development of new anti-viral drugs or a reduction in transmission, perhaps. However, often the story will relate to a gloomier theme, for example, the appearance of new viral epidemics, the evolution of drug resistance, or falling vaccine coverage. The

Transmission of integrin β7 transmembrane domain topology enables gut lymphoid tissue development. [PDF]

open access: yes, 2018
Integrin activation regulates adhesion, extracellular matrix assembly, and cell migration, thereby playing an indispensable role in development and in many pathological processes.

A Series of BRAF- and NRAS-Driven Murine Melanoma Cell Lines with Inducible Gene Modulation Capabilities

open access: yesJID Innovations, 2022
Murine cancer cell lines are powerful research tools to complement studies in genetically engineered mouse models. We have established 21 melanoma cell lines from embryonic stem cell-genetically engineered mouse models driven by alleles that model the ...
