Abstract Background The development of essential hypertension is associated with a wide range of mechanisms. The brain stem neurons are essential for the homeostatic regulation of arterial pressure as they control baroreflex and sympathetic nerve activity. The ISIAH (Inherited Stress Induced Arterial Hypertension) rats reproduce the human stress-sensitive hypertensive disease with predominant activation of the neuroendocrine hypothalamic-pituitary-adrenal and sympathetic adrenal axes. RNA-Seq analysis of the brain stems from the hypertensive ISIAH and normotensive control WAG (Wistar Albino Glaxo) rats was performed to identify the differentially expressed genes (DEGs) and the main central mechanisms (biological processes and metabolic BIO pathways) contributing to the hypertensive state in the ISIAH rats. Results The study revealed 224 DEGs. Their annotation in databases showed that 22 of them were BIO associated with hypertension and blood pressure (BP) regulation, and 61 DEGs were associated with central nervous system diseases. In accordance with the functional annotation of DEGs, the key role of hormonal metabolic processes and, in particular, the enhanced biosynthesis of aldosterone in the mind stem of ISIAH rats was suggested. Multiple DEGs connected with many Gene Ontology (Move) conditions essentially linked to modulation of BP had been identified. Abundant sets of DEGs had been related to Move terms connected with replies to different stimuli including response to organic (hormonal) chemical, to exterior stimulus, also to tension. Several DEGs producing one of the most contribution towards the inter-strain distinctions had been detected like the which was previously defined as a significant applicant gene in the research of transcriptional information in different tissue/organs (hypothalamus, adrenal gland and kidney) of ISIAH rats. Conclusions The outcomes of the analysis demonstrated that inter-strain distinctions in ISIAH and WAG human brain stem functioning may be due to the imbalance in procedures resulting in the pathology advancement and the ones, exerting the compensatory results. The data attained within this research are of help for an improved knowledge of the hereditary mechanisms root the intricacy of the mind stem procedures in ISIAH rats, which certainly are a style of stress-sensitive type of hypertension.

The quantitative real time PCR (qPCR) analysis performed to distinguish between the levels of their expression confirmed the elevated transcription of both genes in the brain stem of ISIAH rats (Fig.?2). The enzymes encoded by and are key players in many BIO biological processes including glucocorticoid (corticosterone) and aldosterone biosynthetic processes. Besides, GO enrichment analysis showed that BP in ISIAH rats may be modulated by multiple DEGs associated with several other GO terms essentially related to BP regulation. These are blood circulation, regulation of BP, regulation of Rabbit polyclonal to IPO13 blood vessel size, regulation of muscle contraction and blood vessel remodeling (Additional file 5: Table S5). Open in a separate window Fig. 2 qPCR measurement of mRNA for the and genes encoding for the 11-hydroxylase and aldosterone synthase enzymes, respectively, in brain stem of ISIAH and WAG rats. The significance of inter-strain difference is usually indicated by * and and expression (Fig. ?(Fig.2)2) are similar to those described in the study of aldosterone synthesis in brain stems from SS rats with salt-sensitive hypertension [22]. The increased transcription of the and genes involved in the steroid biosynthesis in ISIAH brain stem suggests that elevated level of aldosterone synthesis may have an impact to the BIO development of stress-sensitive hypertension, too. It has been long known that this regulation of the vascular resistance in the brain stem plays an important role in the autoregulation of the brain blood flow [24]. In the current study, the vascular easy muscle contraction pathway was one of the most significantly enriched (Fig. ?(Fig.3).3). Altered expression of the DEGs associated with this metabolic pathway might exert different effects on vascular easy.
