The animal models used in biomedical research cover virtually every human disease. RatDEGdb, a knowledge base of the differentially expressed genes (DEGs) of the rat as a model object in biomedical research is a collection of published data on gene expression in rat strains simulating arterial hypertension, age-related diseases, psychopathological conditions and other human afflictions. The current release contains information on 25,101 DEGs representing 14,320 unique rat genes that change transcription levels in 21 tissues of 10 genetic rat strains used as models of 11 human diseases based on 45 original scientific papers.

The mainstream of the post-genome target-assisted breeding in crop plant species includes biofortification such as high-throughput phenotyping along with genome-based selection. Therefore, in this work, we used the Web-service Plant_SNP_TATA_Z-tester, which we have previously developed, to run a uniform in silico analysis of the transcriptional alterations of 54,013 protein-coding transcripts from 32,833 L. genes caused by 871,707 SNPs located in the proximal promoter region.

Atherosclerosis is a systemic disease in which focal lesions in arteries promote the build-up of lipoproteins and cholesterol they are transporting. The development of atheroma (atherogenesis) narrows blood vessels, reduces the blood supply and leads to cardiovascular diseases. According to the World Health Organization (WHO), cardiovascular diseases are the leading cause of death, which has been especially boosted since the COVID-19 pandemic.

Article Synopsis
  • The study investigates how gene expressions linked to age-related diseases (ARDs) vary among different genders, ages, and disease types to improve personalized medicine approaches.
  • Researchers sequenced the transcriptome of two types of rats—tame and aggressive—to find behavior-related gene expressions and compared them to known ARD-linked genes.
  • The analysis revealed a significant correlation between the gene expressions related to behavior and ARD susceptibility, identifying a key molecular marker: an excess of Fcγ receptor IIb, which suppresses immune hyperactivation.

It is generally accepted that during the domestication of food plants, selection was focused on their productivity, the ease of their technological processing into food, and resistance to pathogens and environmental stressors. Besides, the palatability of plant foods and their health benefits could also be subjected to selection by humans in the past. Nonetheless, it is unclear whether in antiquity, aside from positive selection for beneficial properties of plants, humans simultaneously selected against such detrimental properties as allergenicity.

Synthetic targeted optimization of plant promoters is becoming a part of progress in mainstream postgenomic agriculture along with hybridization of cultivated plants with wild congeners, as well as marker-assisted breeding. Therefore, here, for the first time, we compiled all the experimental data-on mutational effects in plant proximal promoters on gene expression-that we could find in PubMed. Some of these datasets cast doubt on both the existence and the uniqueness of the sought solution, which could unequivocally estimate effects of proximal promoter mutation on gene expression when plants are grown under various environmental conditions during their development.

Article Synopsis
  • Hypertension often runs in families, but genetic research shows that known genetic factors only account for a small part of its heredity, prompting the need for more personalized treatment approaches.
  • The study aimed to identify universal genetic markers for hypertension by analyzing gene expression in the brains of rats with different stress levels, linking stress reaction to hypertension risk.
  • Findings revealed two potential biomarkers—β-protocadherins and hemoglobin—that are downregulated in hypertensive patients and could be used in broader hypertension management strategies.
