Analysis of the abomasal transcriptome of LDA affected cattle

Left displacement of the abomasum (LDA) is a common condition in Holstein population mainly occur around the time of parturition. The entrapped abomasum located between the rumen and the abdominal wall caused by the abomasal hypomotility. The heritability of LDA estimated higher than for other bovine diseases but a number of management and nutritional conditions are also affecting the disease appearance. Genome studies revealed many significant genomic regions associated with LDA, although an RNA sequencing analysis of abomasum is missing from the literature. Within the framework of this research, we tried to patch up this area missing from the literature and to reveal the genetic causes and a complex interaction between the endocrine and neuromuscular pathways behind the symptoms of the disease with the help of transcriptomic analysis.

Complete blood count and selected serum parameters of Venus transgenic rabbits

Green fluorescent protein (GFP) transgenic laboratory animals (mice, rats, rabbits etc.) are commonly used in basic research for modelling human diseases, studying organ development, cell transfer during pregnancy or tissue engineering. The expression of the fluorescent protein can be either ubiquitous or tissue-specific, depending on the transgenic construct and the integration site of the transgene. Despite the wide applications, the data about the physiological parameters of GFP transgenic animals are limited. In most of the transgenic lines, GFP does not induce any detrimental effect, but GFP-induced conditions are also reported. Altered T-lymphopoiesis and low white blood cell (WBC) count were observed in human ubiquitin C promoter-driven GFP transgenic (UBC-GFP) mice due to latent stem cell defect. The aim of the present study was to examine the effects of the Venus fluorescent protein on hematopoiesis and general health of transgenic rabbits, thus, hematology along with selected serum parameters were measured.

Patterns of numtogenesis in sixteen different mice strains

1Numtogenesis is the phenomenon of mitochondrial sequence localisation and integration into the nuclear genome. This is an ongoing process which contributed to the complexity of eukaryotic genomes. The sequences that are integrated into the nuclear genome are called nuclear mitochondrial sequences (numt). numts have a wide variety of applications in tumor biology, phylogenetic studies, forensic research and so on. Mus musculus musculus is the most popular model organism. Numerous mouse strains are used in medical research to model human diseases. Numts were described in the genome of Mus musculus musculus just like in many other species however the characterisation of numts in different mouse strains is missing. In this study we explored the patterns of numtogenesis in 16 mouse strains by aligning the nuclear genomes with the corresponding mitochondria. Investigation of numts shed light on strain specific differences and resembles the phylogenetic relationships as to our current knowledge in most of the cases.
