Impact of media supplementation on a transcriptional activity of porcine embryos produced in vitro

ABSTRACT: The production of embryos in vitro caused a revolution in the field of assisted reproduction technologies, which currently allows the manipulation and selection of embryos before implantation. One of the key aspects of this process is the maturation of oocytes in a controlled in vitro environment. In this article, we focused on the impact of precisely chemically modified FLI maturation medium and its potential in improving the efficiency of in vitro production of porcine embryos. Based on our findings, we demonstrated the positive influence of FLI medium in the evaluation of in vitro maturation, in vitro embryo production, EGA detection, transcriptomic profile and proteomic analysis, which was confirmed by the positive activation of the embryonal genome in the 4blastoembry stage of parthenogenetically activated embryos.

Project description:In Brazil, the incidence and prevalence of CKD are increasing, the prognosis remains poor and the costs of treating the disease are very high. Added to this is the increase in the main risk factors for the development and progression of CKD, such as greater aging of the population, high prevalence of AH, DM, overweight, smoking and others, which suggests the continuation of CKD as a serious problem of public health. This situation requires prevention actions, early diagnosis of the disease and agile action in the face of the functional changes evidenced. Furthermore, there is a need to find ways to prevent the progression of the disease. A disturbing issue in nephrology practice is the observation that a significant number of CKD patients lose renal function asymptomatically. One of the reasons is late diagnosis and referral to dialysis. The main causes are: the fact that CKD is often asymptomatic, difficulty in diagnosis, tendency of doctors not to refer patients adequately, selection of patients with less morbidities to start dialysis, resistance of patients to treatment, deficient structure of the health system and lack of access to treatment. The consequences of late referral are reflected in greater morbidity, mortality, costs and worse quality of life. In this sense, it is important to search for new markers of the disease that allow early diagnosis, monitoring of progression and, eventually, improving response to treatment. Analyzing mechanisms underlying renal failure and identifying unique biomarkers (such as metabolite ratios) have the potential to increase our understanding of CKD and improve disease diagnosis and treatment algorithms. In this sense, this project can represent important progress in CKD proteomics research, based on complex information obtained from proteomics associated with basic medical information. New biomarkers are needed as non-invasive tools to aid the accurate diagnosis of kidney diseases with similar clinical characteristics but different prognosis. This project aims to investigate the proteomics of saliva from chronic kidney disease patients in the search for molecular markers that can be used in both the diagnosis and prognosis of the disease. So, for this, it was necessary to select healthy individuals and chronic kidney disease patients, and collect sociodemographic, behavioral, food consumption, clinical and anthropometric data from these individuals. Next, the mass spectrometry proteomics technique was performed on saliva samples and investigated molecules that could be used as markers of CKD and other associated comorbidities, in addition to evaluating whether any molecule could be indicative of the progression of CKD.
