The Odyssey of the Ancestral Escherich Strain through Culture Collections: an Example of Allopatric Diversification

open access: yesmSphere, 2018
More than a century ago, Theodor Escherich isolated the bacterium that was to become Escherichia coli, one of the most studied organisms. Not long after, the strain began an odyssey and landed in many laboratories across the world.

Molecular characterization of a rice mutator-phenotype derived from an incompatible cross-pollination reveals transgenerational mobilization of multiple transposable elements and extensive epigenetic instability

open access: yesBMC Plant Biology, 2009
Background Inter-specific hybridization occurs frequently in plants, which may induce genetic and epigenetic instabilities in the resultant hybrids, allopolyploids and introgressants.

THAP1 mutations and dystonia phenotypes: Genotype phenotype correlations [PDF]

open access: yesMovement Disorders, 2012
AbstractTHAP1 mutations have been shown to be the cause of DYT6. A number of different mutation types and locations in the THAP1 gene have been associated with a range of severity and dystonia phenotypes, but, as yet, it has been difficult to identify clear genotype phenotype patterns.

Chromosomal Islands of Streptococcus pyogenes and related streptococci: Molecular Switches for Survival and Virulence

open access: yesFrontiers in Cellular and Infection Microbiology, 2014
Streptococcus pyogenes is a significant pathogen of humans, annually causing over 700,000,000 infections and 500,000 deaths. Virulence in S. pyogenes is closely linked to mobile genetic elements like phages and chromosomal islands (CI). S.

Identification of MLH2/hPMS1 dominant mutations that prevent DNA mismatch repair function

open access: yesCommunications Biology, 2020
Reyes et al. identified and characterized dominant mutations in the MutL homolog MLH2 (in S. cerevisiae) and PMS1 (in humans) causing an increased mutator phenotype.

Loss of DNA mismatch repair imparts a selective advantage in planarian adult stem cells. [PDF]

open access: yesPLoS ONE, 2011
Lynch syndrome (LS) leads to an increased risk of early-onset colorectal and other types of cancer and is caused by germline mutations in DNA mismatch repair (MMR) genes.

Rab38 Mutation and the Lung Phenotype [PDF]

open access: yesInternational Journal of Molecular Sciences, 2018
Rab38 is highly expressed in alveolar type II cells, melanocytes, and platelets. These cells are specifically-differentiated cells and contain characteristic intracellular organelles called lysosome-related organelles, i.e., lamellar bodies in alveolar type II cells, melanosomes in melanocytes, and dense granules in platelets.

PAX6 mutations: genotype-phenotype correlations [PDF]

open access: yesBMC Genetics, 2005
Abstract Background The PAX6 protein is a highly conserved transcriptional regulator that is important for normal ocular and neural development. In humans, heterozygous mutations of the PAX6 gene cause aniridia (absence of the iris) and related developmental eye diseases.

Mismatch Repair of DNA Replication Errors Contributes to Microevolution in the Pathogenic Fungus Cryptococcus neoformans

open access: yesmBio, 2017
The ability to adapt to a changing environment provides a selective advantage to microorganisms. In the case of many pathogens, a large change in their environment occurs when they move from a natural setting to a setting within a human host and then ...

Mutator phenotype in cancer: origin and consequences. [PDF]

open access: yesSemin Cancer Biol, 2010
The concept that cancers express a mutator phenotype was formulated eons ago1. Its origin stems from observations that within each tumor there are many different chromosomal alterations in each malignant cell and the shape and structure of these cells are strikingly heterogeneous.
