A number of variables, including a poor dietary and lifestyle, genetics, metabolic problems, and inheritance, are linked to the risk of CRC. However, it has been studied extensively about the involvement of various environmental factors which facilitates the development of this particular type of cancer in both genders. These elements includes excessive consumption of meat, refined grain and their products, starch, sugars in distinct forms, and alcohol are at top of the list. Hence, to execute the significance of <em>Lactobacillus acidophilus</em> CGMCC 878 (L.A 878) which may possibly hinder the development as well as progression of chemically induce colorectal tumor in <em>in-vivo</em> model via transformation of gut microbiota. We had established CRC in male Sprague-Dawley rats through subcutaneously inject the carcinogen named 1,2 dimethylhydrazine hydrochloride (DMH). We had detected the microbial diversity among different groups which included in the study by evaluation of stool samples by the virtue of molecular genetic computation. Although, we had targeted the bacterial V3 region by using classic molecular technique of PCR-DGGE (Polymerase chain reaction- Denaturing Gradient Gel Electrophoresis) followed by excision of amplified bands and were cloned for sequencing. The DGGE profiles of distinct groups demonstrated significant alterations between DMH group, short-term L. acidophilus group (p ​&lt; ​0.05), and the long-term L. acidophilus group (P 0.001). The fecal-glucuronidase was significantly overexpressed in DMH group associated with long-term L. acidophilus group (p ​&lt; ​0.05). Hence, prolong administration of L.A 878 could reduce the development of colorectal tumors in rats by altering the intestinal pathogenic bacteria (Ruminococcus obeum, Clostridium thermocellum, Bacteroides vulgates, Mycoplasma leachii, Porphyromonas asaccharolytica) and beneficial bacteria (Lactobacillus reuteri, Lactobacillus). These observations suggested that Lactobacillus acidophilus CGMCC 878 may have therapeutic potential in attenuating carcinogenesis of gastrointestinal (GI) tract.</p></div>","PeriodicalId":36019,"journal":{"name":"Medicine in Microecology","volume":"14 ","pages":"Article 100062"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S259009782200012X/pdfft?md5=d085b2690988bd0714e1d25914fdd1a1&pid=1-s2.0-S259009782200012X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44797541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Acupuncture therapy reportedly alleviates the symptoms of patients with autism and can regulate the gut microbiota of patients with a disease of the central nervous system via the gut microbiota-brain axis. However, whether acupuncture therapy influences the function and composition of the gut microbiota in patients with autism remains unclear. Therefore, the present study was conducted using a valproic acid (VPA)-induced autism mouse model to investigate how acupuncture therapy influences the intestinal microbiota in terms of species diversity, composition, and function. Mice were treated with VPA to induce autism, and then divided into two groups: autism without treatment (ASD) and autism with manual acupuncture (ASD-MA). Mice in the ASD-MA group were treated with acupuncture once daily for four weeks. And behavior test was performed. Total bacterial DNA was extracted from stool samples to amplify and sequence the V3–V4 regions of 16 ​S rRNA. The alpha and beta diversity were analyzed, and changes in intestinal microbiota composition at various taxonomic levels were analyzed. The Morris water maze test results showed that the number of times the mice reached the platform was significantly higher in the ASD-MA group than in the ASD group. The results of nonmetric multidimensional scaling and principal coordinate analysis, which were used for beta diversity analyses, revealed significant differences in the microbial communities between the ASD and ASD-MA groups. The ASD-MA group mice had changed abundances of some specific microbiota, which were positively correlated with better cognitive performance. Accordingly, the gut microbiota, such as <em>Flavonifractor</em>, <em>Akkermansia</em>, <em>Dorea</em>, <em>Ruminococcus</em>, and <em>Barnesiella</em>, may affect cognitive function of VPA-induced autism mice after acupuncture treatment. In conclusion, the results revealed that acupuncture therapy could affect the composition of the gut microbiota in mice with VPA-induced autism-like behavior.</p></div>","PeriodicalId":36019,"journal":{"name":"Medicine in Microecology","volume":"14 ","pages":"Article 100066"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590097822000167/pdfft?md5=d5772f3fa2d80afc08e51924ddf14b05&pid=1-s2.0-S2590097822000167-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44014479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
