Transcriptional regulation of LMW glutenin genes were investigated in-silico, using publicly available gene sequences and expression data. Genes were grouped into different LMW glutenin types and their promoter profiles were determined using cis-acting regulatory elements databases and published results. The various cis-acting elements belong to some(More)
The precise elimination of selectable marker genes is highly desirable, when their function is no longer needed, because their presence raised worldwide public concerns against the release of genetically modified plants. This is the first report of simultaneous application of the minimal gene cassette and cold-inducible Cre/lox recombination system in(More)
Sensorineural hearing losses (SNHLs; e.g., ototoxicant- and noise-induced hearing loss or presbycusis) are among the most frequent sensory deficits, but they lack effective drug therapies. The majority of recent therapeutic approaches focused on the trials of antioxidants and reactive oxygen species (ROS) scavengers in SNHLs. The rationale for these studies(More)
Head and neck squamous cell carcinomas (HNSCC) show diverse clinicopathological features and are mostly linked with poor outcome. In this study, we tested if the expression of tumor growth, cell cycle and basement membrane anchorage related biomarkers allow prognostic and clinicopathological stratification of HNSCC. Archived HNSCC samples from 226 patients(More)
In this work, we expressed an Arabidopsis thaliana-coded protein (AKR4C9) in transgenic barley to study its enzymatic activity and to enhance the reactive aldehyde neutralizing capacity (part of the oxidative stress tolerance) of transgenic plants. Total leaf protein was extracted from transgenic plants expressing either C or N-terminally His-tagged(More)
Epitope databases and the protein sequences of published plant genomes are suitable to identify some of the proteins causing food allergies and sensitivities. Brachypodium distachyon, a diploid wild grass with a sequenced genome and low prolamin content, is the closest relative of the allergen cereals, such as wheat or barley. Using the Brachypodium genome(More)
Analysis of gene expression data generated by high-throughput microarray transcript profiling experiments coupled with cis-regulatory elements enrichment study and cluster analysis can be used to define modular gene programs and regulatory networks. Unfortunately, the high molecular weight glutenin subunits of wheat (Triticum aestivum) are more similar than(More)
Wheat has been cultivated for 10000 years and ever since the origin of hexaploid wheat it has been exempt from natural selection. Instead, it was under the constant selective pressure of human agriculture from harvest to sowing during every year, producing a vast array of varieties. Wheat has been adopted globally, accumulating variation for genes involved(More)
Under various stress conditions, plant cells are exposed to oxidative damage which triggers lipid peroxidation. Lipid peroxide breakdown products include protein crosslinking reactive aldehydes. These are highly damaging to living cells. Stress-protective aldo–keto reductase (AKR) enzymes are able to recognise and modify these molecules, reducing their(More)
BACKGROUND This study aimed to determine the ability of multimodal evaluation with multiparametric 3T-MRI (MPMRI) and positron emission tomography - computed tomography (PET/CT) to detect cancer of unknown primary origin (CUP) with neck lymph node (LN) metastasis. METHODS The study group comprised 38 retrospectively analysed consecutive patients with LN(More)
