“…Microbiome refers to the collective genomes of more than 3 million genes of the microorganisms in a particular environment. Gut microbiota, like a virtual endocrine organ, reacts to various internal and external stimuli [5, [75][76][77][78]. Consequently, gut microbiota influences and regulates hosts' health and mood statue including aggression by integrating metabolic, immune, endocrine, and neural reactions through the bidirectional communication of the gut-brain axis (Figure 1) [7, 33,[79][80][81][82][83].…”

Intestinal bacteria release various neuroactive compounds directly or indirectly regulating brain function to modulate host health and behavior through the gut-brain axis. Probiotics have been used as dietary supplements to target gut microbiota (microbiome) for prevention or therapeutic treatment of various diseases including mental disorders. In our study, chickens were used as an animal model to assess, if dietary supplementation of probiotic, Bacillus subtilis, reduces aggressive behaviors following social challenge. Chickens of an aggressive line were housed in single-hen cages. At 24 weeks of age, the hens were paired with similar body weight to identify the dominance rank (day 0). The subordinate and dominant of each pair were fed a regular layer diet or the diet mixed with 250 ppm probiotics for 2 weeks, then the second behavior test was performed between the same pair (day 14). The display of aggressive behaviors in the regular diet-fed chickens was not affected between the levels at day 0 and day 14, while the frequency of threat and aggressive pecking were reduced in the probiotic-fed chickens compared to the levels at day 0. These results suggest dietary probiotic, Bacillus subtilis, could be a suitable strategy for increasing hosts' mental health.

“…The microorganisms that inhabit the gastrointestinal tract are known collectively as the gut microbiota, which consists of approximately 10 trillion bacteria [8]. Importantly, the intestinal microbiome contributes to the pathogenesis of multiple human chronic diseases, such as musculoskeletal diseases, neurological disorders, cardiovascular disease and liver diseases [9][10][11][12][13]. In addition, recent findings provide substantial evidence for the existence of a gut microbiota-bone axis [14][15][16][17][18], and the gut microbiota is a major regulator of bone mineral density (BMD) via the effects of the immune system [18,19].…”

Reduced bone mineral density (BMD) is associated with an altered microbiota in senile osteoporosis. However, the relationship among gut microbiota, BMD and bone metabolic indexes remains unknown in postmenopausal osteoporosis. In this study, fecal microbiota profiles for 106 postmenopausal individuals with osteopenia (n=33) or osteoporosis (n=42) or with normal BMD (n=31) were determined. An integrated 16S rRNA gene sequencing and LC-MS-based metabolomics approach was applied to explore the association of estrogen-reduced osteoporosis with the gut microbiota and fecal metabolic phenotype. Adjustments were made using several statistical models for potential confounding variables identified from the literature. The results demonstrated decreased bacterial richness and diversity in postmenopausal osteoporosis. Additionally, showed significant differences in abundance levels among phyla and genera in the gut microbial community were found. Moreover, postmenopausal osteopenia-enriched N-acetylmannosamine correlated negatively with BMD, and distinguishing metabolites were closely associated with gut bacterial variation. Both serum procollagen type I N propeptide (P1NP) and C-terminal telopeptide of type I collagen (CTX-1) correlated positively with osteopenia-enriched Allisonella, Klebsiella and Megasphaera. However, we did not find a significant correlation between bacterial diversity and estrogen. These observations will lead to a better understanding of the relationship between bone homeostasis and the microbiota in postmenopausal osteoporosis.

Dynamic modulation of gut microbiota improves post‐myocardial infarct tissue repair in rats via butyric acid‐mediated histone deacetylase inhibition

The complex and dynamic population of gut microbiota exerts a marked influence on the host during homeostasis and disease. Imbalance of gut microbiota metabolites may lead to cardiac dysfunction in patients with heart failure, which is related to myocardial infarction(MI) severity. However, the role of gut microbiota in the repair process after MI has rarely been reported. To explore the role of gut microbiota in MI repair and its underlying mechanism, we mixed antibiotics in drinking water to interfere with gut microbiota in rats. Hematoxylin and eosin staining, Sirius red staining, western blotting, and immunohistochemistry were used to detect tissue repair and fibrosis. We found that the expressions of alpha‐smooth muscle actin, collagen, and histone deacetylase (HDAC) activities were significantly increased. We detected gut microbiota at different time points after MI using 16S ribosomal RNA sequencing and detected that Prevotellaceae, Clostridiaceae, and Lachnospiraceae were significantly altered among the butyric acid producers. We administered sodium butyrate via drinking water and discovered that sodium butyrate reduced HDAC activities and adverse repair. Therefore, we speculated that gut microbiota influences the acetylation level and tissue repair process after MI by affecting butyric acid production.
