Rapid nuclear localisation of β-catenin also occurred in the aberrant areas in both genotypes and the time scale for loss of differentiation status of enteroendocrine cells (assessed by Grimelius staining) and Paneth and goblet cell mislocalisation (assessed using anti-Lysozyme IHC and alcian blue staining respectively) was identical in both genotypes.
In most cases of AF, electrical signals begin in aberrant trigger areas, often close to the pulmonary veins.
Penetrance of aberrant chromosomal areas across the genome was demonstrated using Aberration Detection Method 2 (Agilent Genomic Workbench Lite Edition 6.5.0.18, Agilent Technologies), a quality-weighted interval score algorithm that identifies aberrant intervals in samples that have consistent gain or loss log ratios based on their statistical score.
Measurements that have been useful in quantifying the phenotypes of migration inhibition and aberrant morphology include: area of lamellar region, width of lamellar region, and the smoothness of the wound margin.
The ROC analysis suggested that the high-dependence risk-factor score did not provide a very good indication of high risk of aberrant behaviour; the area under the ROC curve (AUROC) was 0.58 (95 % CI 0.41, 0.74), which includes the null AUROC value of 0.5.
It is important to note that the low level of methylation in normal appearing colorectal mucosa observed in our study, in a similar manner as in others [13], [31], may be due to the circumscription of this phenomenon to limited areas (aberrant crypt foci, for instance) rather than a spread, diffuse alteration throughout the colon [39].
Xenografts resulting from the expanded cultures had histological hallmarks of malignant gliomas, including perivascular invasion, aberrant vasculature, and areas of necrosis.
At 10 months old, a large area of aberrant fiber cells was observed.
The two indices were associated (χ df (20) = 58.72, p < 0.001), but a high-dependence risk-factor score provided a poor indication of high aberrant behaviour risk; the area under the receiver operating characteristic curve was 0.58 (95%% CI 0.41, 0.74).
These fish often displayed scattered, distinct areas of aberrant tissue growth along the fin (Fig. 2A, green arrows mark areas of comparatively reduced growth), which can occur normally, at a rate significantly higher (56%) than in WT+MTZ (13.4%) or NTR−MTZ (7.8%) (Fig. 2D).
