    Skeletal muscle gene expression in older adults with type 2 diabetes mellitus undergoing calorie-restricted diet and recreational sports training - a randomized clinical trial
    (2022) SOARES, Diana Bento da Silva; SHINJO, Samuel Katsuyuki; SANTOS, Aritania Sousa; JESUS, Joyce de Cassia Rosa de; SCHENK, Simon; CASTRO, Gabriela Salim de; ZANOTELI, Edmar; KRUSTRUP, Peter; SILVA, Maria Elizabeth Rossi da; SOUSA, Maysa Vieira de
    Aims: This study aimed to evaluate the impact of a 12-week calorie-restricted diet and recreational sports training on gene expressions IL-15, ATROGIN-1 and MURF-1 in skeletal muscle of T2D patients. Methods: Older adults with T2D (n = 39, 60 +/- 6.0 years, BMI 33.5 +/- 0.6 kg/m(2)) were randomly allocated to Diet+Soccer (DS), Diet+Running (DR) or Diet (D). The training sessions were moderate-to-high-intensity and performed 3 x 40 min/week for 12-weeks. Gene expression from vastus lateralis muscle obtained by qRT-PCR, dual-energy X-ray and fasting blood testing measurements were performed before and after 12-weeks. Statistical analysis adopted were two-way ANOVA and Paired t-test for gene expression, and RM-ANOVA test for the remainder variables. Results: Total body weight was reduced in similar to 4 kg representing body fat mass in all groups after 12-weeks (P < 0.05). HbA1c values decreased in all groups post-intervention. Lipids profile improved in the training groups (P < 0.05) after 12-weeks. ATROGIN-1 and MURF-1 mRNA reduced in the DS (1.084 +/- 0.14 vs. 0.754 +/- 1.14 and 1.175 +/- 0.34 vs. 0.693 +/- 0.12, respectively; P < 0.05), while IL-15 mRNA increased in the DR (1.056 +/- 0.12 vs. 1.308 +/- 0.13; P < 0.05) after 12-weeks intervention. Conclusion: Recreational training with a moderate calorie-restricted diet can downregulates the expression of atrophy-associated myokines and increases the expression of anti-inflammatory gene IL-15.

    MiRNA-30d and miR-770-5p as potential clinical risk predictors of Vasoplegic Syndrome in Patients undergoing on-pump coronary artery bypass grafting
    (2023) MEJIA, Omar Asdrubal Vilca; SOUZA, Renato Cesar de; SANTOS, Aritania S.; MENEGHINI, Bianca; SILVA, Ana Carolina Carvalho; BRASIL, Guilherme Visconde; RIGAUD, Vagner Oliveira Carvalho; DALLAN, Luis Roberto Palma; MOREIRA, Luiz Felipe Pinho; LISBOA, Luiz Augusto Ferreira; DALLAN, Luis Alberto Oliveira; KALIL, Jorge; CUNHA-NETO, Edecio; FERREIRA, Ludmila Rodrigues Pinto; JATENE, Fabio Biscegli
    The aims of this study were to perform pre-surgery miRNA profiling of patients who develop Vasoplegic syndrome (VS) after coronary artery bypass grafting (CABG) and identify those miRNAs that could be used as VS prognostic tools and biomarkers. The levels of 754 microRNAs (miRNAs) were measured in whole blood samples from a cohort of patients collected right before the coronary artery bypass grafting (CABG) surgery. We compared the miRNA levels of those who developed VS (VASO group) with those who did not (NONVASO group) after surgery. Six miRNAs (hsa-miR-548c-3p, -199b-5p, -383-5p -571 -183-3p, -30d-5p) were increased and two (hsa-1236-3p, and hsa-miR770-5p) were decreased in blood of VASO compared to NONVASO groups. Receiver Operating Characteristic (ROC) curve analysis revealed that a combination of the miRNAs, hsa-miR-30d-5p and hsa-miR-770-5p can be used as VS predictors (AUC = 0.9615, p < 0.0001). The computational and functional analyses were performed to gain insights into the potential role of these dysregulated miRNAs in VS and have identified the ""Apelin Liver Signaling Pathway"" as the canonical pathway containing the most target genes regulated by these miRNAs. The expression of the combined miRNAs hsa-miR-30d and hsa-miR-770-5p allowed the ability to distinguish between patients who could and could not develop VS, representing a potential predictive biomarker of VS.
