The effect of multiple paternity on genetic diversity during and after colonisation [PDF]

PLoS ONE 8(10) e75587 (2013), 2012
In metapopulations, genetic variation of local populations is influenced by the genetic content of the founders, and of migrants following establishment. We analyse the effect of multiple paternity on genetic diversity using a model in which the highly promiscuous marine snail Littorina saxatilis expands from a mainland to colonise initially empty ...

Downy mildew resistance and genetic variability in a wild rocket germplasm collection

Agronomy Journal, Volume 114, Issue 6, Page 3083-3095, November/December 2022., 2022
Abstract One hundred accessions of a “core collection” of Diplotaxis tenuifolia (L.) DC. and Eruca spp. were screened at seedling stage for resistance to downy mildew. Accessions tested at the seedling stage were assigned to 0–6 interaction phenotypes.

The cell cycle stage of bovine zygotes electroporated with CRISPR/Cas9-RNP affects frequency of Loss-of-heterozygosity editing events

Scientific Reports, 2022
At the embryonic level, CRISPR technologies have been used to edit genomes reliably and efficiently in various mammalian models, with Ribonucleoprotein (RNP) electroporation potentially representing a superior delivery method into mammalian zygotes ...

Using somatic mutation data to test tumors for clonal relatedness [PDF]

Annals of Applied Statistics 2015, Vol. 9, No. 3, 1533-1548, 2015
A major challenge for cancer pathologists is to determine whether a new tumor in a patient with cancer is a metastasis or an independent occurrence of the disease. In recent years numerous studies have evaluated pairs of tumor specimens to examine the similarity of the somatic characteristics of the tumors and to test for clonal relatedness.

A phase II study of neoadjuvant capecitabine, oxaliplatin, and irinotecan (XELOXIRI) in patients with locally advanced rectal cancer

Annals of Gastroenterological Surgery, Volume 7, Issue 1, Page 81-90, January 2023., 2023
XELOXIRI neoadjuvant chemotherapy appears to be feasible and efficacious for patients with LARC. Although neoadjuvant XELOXIRI alone did not yield our expected pCR rate, the local recurrence rate, 3‐year DFS and measures of safety met current standards.

Loss of expression and promoter methylation of SLIT2 are associated with sessile serrated adenoma formation. [PDF]

PLoS Genetics, 2013
Serrated adenomas form a distinct subtype of colorectal pre-malignant lesions that may progress to malignancy along a different molecular pathway than the conventional adenoma-carcinoma pathway.

Microsatellite Instability and Loss of Heterozygosity in Melanoma

Journal of Investigative Dermatology, 1995
Alterations in the repeat length of microsatellites have been identified recently in tumors arising in patients with hereditary nonpolyposis colon cancer and in several human sporadic tumors. We examined 40 sporadic melanomas and their corresponding nontumorous skin for microsatellite instability (MSI) and loss of heterozygosity (LOH) at chromosomes 2q,

Familial Adenomatous Polyposis: Analysis of Genetic Instability of Microsatellites Loci and Genetic Alternations of Tumor Suppressor Genes

Biomolecules & Biomedicine, 2008
Familial adenomatous polyposis (FAP) is an autosomal dominant illness with the highest risk for appearance of colorectal cancer’s disease. In our study, we have used Bethesda criteria that define colorectal cancers which can be tested on microsatellite ...

Patterns of Genomic Instability in Interspecific Yeast Hybrids With Diverse Ancestries

Frontiers in Fungal Biology, 2021
The genomes of hybrids often show substantial deviations from the features of the parent genomes, including genomic instabilities characterized by chromosomal rearrangements, gains, and losses.

Familial Bainbridge‐Ropers syndrome: Report of familial ASXL3 inheritance and a milder phenotype

American Journal of Medical Genetics Part A, Volume 191, Issue 1, Page 29-36, January 2023., 2023
Abstract De novo truncating and splicing pathogenic variants in the Additional Sex Combs‐Like 3 (ASXL3) gene are known to cause neurodevelopmental delay, intellectual disability, behavioral difficulties, hypotonia, feeding problems and characteristic facial features.
