A sex-reversal syndrome appears frequently in the horse. The mare carriers of this syndrome lack of SRY gene. It is suggested that sex-reversal syndrome is probably caused by transfer of the SRY gene from Y to the X chromosome, due to abnormal meiotic exchange. The aim of the study was molecular analysis of the Y-linked genes in a case of the sex-reversed(More)
UNLABELLED REASONS FOR STUDY: Equine recurrent airway obstruction (RAO) is probably dependent on a complex interaction of genetic and environmental factors and shares many characteristic features with human asthma. Interleukin 4 receptor a chain (IL4RA) is a candidate gene because of its role in the development of human asthma, confirmation of this(More)
Five hundred young horses of the following breeds: Thoroughbred, Silesian, Malopolska, Wielkopolska, Polish Konik, Hutsul, Shetland Pony, Half-bred Anglo-Arabian, Noble Half-bred, Fjord and crosses were cytogenetically investigated. Chromosome preparations obtained after lymphocyte culture were analysed using conventional Giemsa staining and CBG-banding(More)
Fluorescent in situ hybridisation (FISH) using a panel of molecular probes for all chromosome pairs obtained by chromosome microdissection of the domestic horse ( Equus caballus ) was used to diagnose karyotype abnormalities in 35 horses (32 mares, 2 stallions and 1 intersex), which were selected for the study due to infertility (23 horses), reduced(More)
We have analysed the chromosomes of three wild and endangered canid species: the maned wolf (Chrysocyon brachyurus), the bat-eared fox (Otocyon megalotis) and the fennec fox (Fennecuszerda) using classical and molecular cytogenetic methods. For the first time detailed and encompassing descriptions of the chromosomes are presented including the chromosomal(More)
Despite its antioxidant capacity and well-known health benefits, yerba mate tea (Ilex paraguariensis) has been shown to possess some genotoxic and mutagenic activities and to increase incidence of some types of cancer. The aim of this study was to estimate the cyto- and genotoxicity of mate tea in human peripheral lymphocytes in vitro. We found that yerba(More)
The technique of silver staining of nucleolar organizer regions (AgNORs) was chosen to estimate the transcriptionally active metaphase and interphase nucleolar organizer regions (NORs) in pig peripheral blood lymphocytes exposed to oxidative agents in vitro. The quantitative analysis of AgNORs was performed by using the counting method and the morphometric(More)
In yeast, rRNA genes can be detected with the FISH technique using rRNA gene probes. This technique yields reliable, reproducible and precise results, but is time-consuming. Here, the primed in situ DNA synthesis (PRINS) procedure has been optimized for rapid detection of yeast rRNA genes. PRINS, which is as sensitive as PCR and allows cytological(More)
Cytogenetic and molecular genetic studies of an intersex horse have been carried out. The investigated animal had overall male body conformation; however, its external genitalia consisted of incompletely developed vulva and penis. The X and Y chromosome painting probes detected three cell lines in the examined horse: 63,X, 64,XX and 65,XX with a fragment of(More)
Thymic stromal lymphopoietin (TSLP) is a novel cytokine that plays a central role in T helper 2 (Th2) cell differentiation and allergic inflammation. It is predominantly expressed by epithelial cells, and its expression is increased in patients with atopic dermatitis and asthma. Mice overexpressing TSLP in the skin develop allergic dermatitis and mice(More)
