Abstract

BACKGROUND: Several evidences indicate that gut microbiota is involved in the control of host energy metabolism. OBJECTIVE: To evaluate the differences in the composition of gut microbiota in rat models under different nutritional status and physical activity and to identify their associations with serum leptin and ghrelin levels. METHODS: In a case control study, forty male rats were randomly assigned to one of these four experimental groups: ABA group with food restriction and free access to exercise; control ABA group with food restriction and no access to exercise; exercise group with free access to exercise and feed ad libitum and ad libitum group without access to exercise and feed ad libitum. The fecal bacteria composition was investigated by PCR-denaturing gradient gel electrophoresis and real-time qPCR. RESULTS: In restricted eaters, we have found a significant increase in the number of Proteobacteria, Bacteroides, Clostridium, Enterococcus, Prevotella and M. smithii and a significant decrease in the quantities of Actinobacteria, Firmicutes, Bacteroidetes, B. coccoides-E. rectale group, Lactobacillus and Bifidobacterium with respect to unrestricted eaters. Moreover, a significant increase in the number of Lactobacillus, Bifidobacterium and B. coccoides-E. rectale group was observed in exercise group with respect to the rest of groups. We also found a significant positive correlation between the quantity of Bifidobacterium and Lactobacillus and serum leptin levels, and a significant and negative correlation among the number of Clostridium, Bacteroides and Prevotella and serum leptin levels in all experimental groups. Furthermore, serum ghrelin levels were negatively correlated with the quantity of Bifidobacterium, Lactobacillus and B. coccoides-Eubacterium rectale group and positively correlated with the number of Bacteroides and Prevotella. CONCLUSIONS: Nutritional status and physical activity alter gut microbiota composition affecting the diversity and similarity. This study highlights the associations between gut microbiota and appetite-regulating hormones that may be important in terms of satiety and host metabolism.

  • Proposed mechanisms for pesticide pathology include a combination of inflammatory dysregulation and metabolic alterations, such as insulin resistance and ghrelin-dysregulation that produces neurodegeneration.

    “Proposed mechanisms for this pathology include a combination of inflammatory dysregulation and metabolic alterations, such as insulin resistance and ghrelin-dysregulation that produces neurodegeneration [195, 196].”

    From The gut–brain axis in early Parkinson’s disease: from prodrome to prevention (2025) · cites this paper as [196]

    The Introduction (page unavailable) discusses ghrelin, metabolism, and eating disorders, not pesticide pathology. Searches for pesticide exposure, inflammatory dysregulation, insulin resistance, and neurodegeneration found no passage linking these to the proposed mechanism. (LLM, conf=0.76)

  • Leptin and ghrelin can be sensed by gut bacteria and finely tune the gut microbiota composition in rodents.

    “A number of these hormones can be sensed by the gut bacteria, as in the case of leptin and ghrelin, which, in turn, finely tune the gut microbiota composition in rodents [29,30].”

  • Exercise appears to be able to enrich microbiota diversity.

    “Exercise appears to be able to enrich microbiota diversity [20–25]”
  • SCFA butyrate, as well as physical exercise, reduce serum ghrelin levels through involvement of FFA3 receptor.

    “Moreover, the SCFA butyrate, as well as physical exercise, reduce serum ghrelin levels through involvement of FFA3 receptor [105, 318].”
  • Serum ghrelin levels are negatively correlated with abundance of certain gut bacteria, including commensal Bifidobacterium and Lactobacillus strains.

    “Interestingly, serum ghrelin levels are negatively correlated with the abundance of certain gut bacteria, including the commensal Bifidobacterium and Lactobacillus strains [318].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
