Inactivation and inducible oncogenic mutation of p53 in gene targeted pigs. [PDF]

open access: yes, 2012
Mutation of the tumor suppressor p53 plays a major role in human carcinogenesis. Here we describe gene-targeted porcine mesenchymal stem cells (MSCs) and live pigs carrying a latent TP53(R167H) mutant allele, orthologous to oncogenic human mutant TP53 ...

Proinflammatory activation of microglia in the cerebellum hyperexcites Purkinje cells to trigger ataxia

open access: yesPharmacological Research, 2023
Specific medications to combat cerebellar ataxias, a group of debilitating movement disorders characterized by difficulty with walking, balance and coordination, are still lacking.

Three-Dimensional X-ray Imaging of β-Galactosidase Reporter Activity by Micro-CT: Implication for Quantitative Analysis of Gene Expression

open access: yesBrain Sciences, 2021
Acquisition of detailed anatomical and molecular knowledge from intact biological samples while preserving their native three-dimensional structure is still a challenging issue for imaging studies aiming to unravel a system’s functions. Three-dimensional

An entropy-based method to measure phase-locking between LFP and spikes

open access: yesAIP Advances, 2023
Phase-locking between local field potential and spikes has been widely investigated through neurophysiological analysis. Two indices most frequently adopted traditionally include the mean resultant length and p of the Rayleigh test.

The contribution of maternal oral, vaginal, and gut microbiota to the developing offspring gut

open access: yesScientific Reports, 2023
There is limited understanding of how the microbiota colonizing various maternal tissues contribute to the development of the neonatal gut microbiota (GM). To determine the contribution of various maternal microbiotic sites to the offspring microbiota in

Neonatal ketone body elevation regulates postnatal heart development by promoting cardiomyocyte mitochondrial maturation and metabolic reprogramming

open access: yesCell Discovery, 2022
Neonatal heart undergoes metabolic conversion and cell cycle arrest preparing for the increased workload during adulthood. Herein, we report that neonatal ketone body elevation is a critical regulatory factor for postnatal heart development.

Familial ALS-superoxide dismutases associate with mitochondria and shift their redox potentials [PDF]

open access: yes, 2006
Recent studies suggest that the toxicity of familial amyotrophic lateral sclerosis mutant Cu, Zn superoxide dismutase (SOD1) arises from its selective recruitment to mitochondria. Here we demonstrate that each of 12 different familial ALS-mutant SOD1s

Functional loss of Ccdc151 leads to hydrocephalus in a mouse model of primary ciliary dyskinesia

open access: yesDisease Models & Mechanisms, 2019
Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disorder affecting normal structure and function of motile cilia, phenotypically manifested as chronic respiratory infections, laterality defects and infertility.

Phenotypic mixing and hiding may contribute to memory in viral quasispecies [PDF]

open access: yes, 2003
Background. In a number of recent experiments with food-and-mouth disease virus, a deleterious mutant, was found to avoid extinction and remain in the population for long periods of time. This observation was called quasispecies memory.

Invariants of genus 2 mutants [PDF]

open access: yes, 2007
Pairs of genus 2 mutant knots can have different Homfly polynomials, for example some 3-string satellites of Conway mutant pairs. We give examples which have different Kauffman 3-variable polynomials, answering a question raised by Dunfield et al in ...
