Background. Microsatellites are short tandem nucleotide repeats, the change in length of which plays a key roles in the pathogenesis of various malignant neoplasms. This change is called microsatellite instability. It is caused by aberrations in the genes of DNA mismatch repair system. Tumors with m...

Background: Numerous prognostic biological markers linked to survival have been identified over the years; however, only few have undergone rigorous evaluation for their diagnostic accuracy. Molecular laboratory techniques like microarrays, microsatellites, and single-nucleotide polymorphisms (SNPs)...

Background. Microsatellite (SSR) markers are now widely used both for studying genetic diversity in fruit crop collections, including apple (Malus × domestica Borkh.), and for genotyping individual accessions. The apple collection held by VIR, being the largest in Russia, contains cultivars bred at...

Background. Genetic instability, an important phenomenon involved in oncogenic transformation and tumor progression, is associated with the insufficiency of the multicomponent DNA repair complex, in particular, the nucleotide mismatch repair (MMR) system. The MMR defect manifests itself as abnormali...

Comparative studies of eight methods for evaluation of genetic differences by microsatellite (STR) markers (11 loci) DNA were carried out using the example of seven breed samples (N = 84) of dairy cattle. The range of indicators of genetic diversity of samples was as follows: the number of alleles p...

Anseriformes represent a basal order in the phylogeny of neognath birds and are of particular interest in cytogenetic research due to their distinctive chromosomal features. However, aspects of their chromosomal evolution, such as the distribution and organization of microsatellite sequences, remain...

The aim was to ascertain the genetic and geographical structure of the Kyrgyz mountain merino (KMM). We analyzed DNA samples of 109 Kyrgyz mountain merino specimens, bred in three state breeding factories (STB), including“Orgochor” in the Issykul Province,“Katta-Taldyk” in the Osh Province and STb n...

High profitability of linseed flax production is an incentive for developing new varieties with high yield performance and for expansion of cultivation areas. The restricted genetic diversity of Linum usitatissimum L. due to selfpollination and of initial forms used by developing the new linseed fla...

One of the main tasks of genetics and animal breeding is the assessment of genetic diversity and the study of genetic relationships between different breeds and populations using molecular genetic analysis methods. We analysed the polymorphism of microsatellites and the information on the state of g...

The common cutworm, Spodoptera litura (Lepidoptera: Noctuidae), is a voracious agricultural pest. To increase understanding of the migration patterns and genetic diversity of different geographic populations of this species, we analyzed genetic variation in nine microsatellite loci among 576 individ...
