Data_Sheet_4_A Constraint-Based Model Analysis of Enterocyte Mitochondrial Adaptation to Dietary Interventions of Lipid Type and Lipid Load.XLSX

<p>Computational modeling of mitochondrial adaptability and flexibility in the small intestine upon different nutritional exposures will provide insights that will help to define healthy diet interventions. Therefore, a murine enterocyte-specific mitochondrial constraint-based metabolic model (named MT_mmuENT127) was constructed and used to simulate mitochondrial behavior under different dietary conditions, representing various levels and composition of nutrients absorbed by the enterocytes in mice, primarily focusing on metabolic pathways. Our simulations predicted that increasing the fraction of marine fatty acids in the diet, or increasing the dietary lipid/carbohydrate ratio resulted in (i) an increase in mitochondrial fatty acid beta oxidation, and (ii) changes in only a limited subset of mitochondrial reactions, which appeared to be independent of gene expression regulation. Moreover, transcript levels of mitochondrial proteins suggested unaltered fusion–fission dynamics by an increased lipid/carbohydrates ratio or by increased fractions of marine fatty acids. In conclusion, our enterocytic mitochondrial constraint-based model was shown to be a suitable platform to investigate effects of dietary interventions on mitochondrial adaptation and provided novel and deeper insights in mitochondrial metabolism and regulation.</p

Presence of anti-Müllerian hormone (AMH) during follicular development in the porcine ovary - Fig 1

<p>Representative AMH staining (brown) in the porcine ovary: (A) 1. Small preantral follicle, 2. Primary follicle, 3. Recruited primordial follicle, 4. Quiescent primordial follicle in which AMH staining is absent; (B) Large preantral follicle; (C) Small antral follicle. Oocytes are indicated by arrows, AMH positive granulosa cells by asterisks and theca cells by arrowheads. Scale bars represent 15 μm (A), 30 μm (B), 60 μm (C).</p

Semi-quantitative analysis of AMH staining during follicular development in the porcine ovary.

<p>AMH staining was quantified in recruited primordial, primary, small preantral, large preantral, small antral, large antral and preovulatory follicles using KS300 software coupled to a Zeiss image analyzer. Low OD values correspond to strong AMH immunostaining. OD values are expressed as grey units (for more details see <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0197894#sec005" target="_blank">Materials and Methods</a>). Values are expressed as mean ± SEM. AMH negative stroma tissue served as a control. Different characters represent significant differences in AMH staining intensity between follicle types (b–P < 0.05; c–P < 0.01).</p
