Abstract
Description
[Technical field]
[0001] The present invention relates to a composition used for removing Fusobacterium and / or Streptococcus bacteria, treating or preventing diseases caused by these bacteria, and treating or preventing colorectal cancer, esophageal cancer, inflammatory bowel disease, infective endocarditis, bacteremia, periodontal disease or dental caries. [Background technology]
[0002] Fusobacterium is a bacterium that mainly lives in the oral cavity and is known to cause periodontal disease, but recent research has revealed that it is also involved in a variety of diseases.
[0003] Since the early 2010s, numerous reports have emerged suggesting that Fusobacterium nucleatum may be related to the carcinogenesis of colorectal cancer (e.g., Non-Patent Document 1). The mechanism by which Fusobacterium nucleatum is related to carcinogenesis is said to be related to FadA and Fap2 expressed by Fusobacterium nucleatum. It is also thought to be related to the progression of colorectal cancer by evading lymphocyte attacks on cancer cells and by avoiding apoptosis. Furthermore, Fusobacterium nucleatum is related to the promotion of cell proliferation, and the effect of overexpression of microRNA on cancer suppressor genes has also been discussed (Non-Patent Document 2).
[0004] Inflammatory bowel disease (IBD) is broadly classified into ulcerative colitis (UC) and Crohn's disease (CD), and has been said to be an autoimmune disease in which inflammatory cells, mainly lymphocytes, attack the intestinal mucosa of the patient due to immune abnormalities, causing inflammation and ulcers. However, the theory that IBD is an intestinal bacterial infection has become popular based on the following facts: spontaneous immune abnormality enteritis does not develop in a sterile environment; there are abnormally many bacteria in the intestinal mucosa of IBD patients; bad bacteria are more prevalent than good bacteria in the intestinal flora compared to normal people; gene polymorphism analysis has revealed that there are many gene polymorphisms in IBD patients that are linked to a decrease in the bacterial elimination mechanism and mucosal defense mechanism; tolerance to intestinal bacteria is decreased in IBD patients, causing excessive immune reactions (inflammation); and Toll-like receptor (TLR), the main component of natural immunity, is expressed in the intestinal epithelium, and many of them use bacteria as ligands (Non-Patent Document 3).
[0005] More specifically, it has been reported that the detection rate of Fusobacterium varium in the inflamed mucosa of UC patients is significantly higher than that of healthy individuals, and that serum antibody titers are also significantly higher in UC patients. Furthermore, using immunohistochemical staining, it has been demonstrated that Fusobacterium varium is present at a higher rate in the inflamed mucosa than in patients with other diseases or healthy individuals (Non-Patent Document 4).
[0006] Furthermore, Fusobacterium varium exhibits cytotoxicity to Vero cells despite the lack of the Verotoxin gene. This is because the butyric acid produced by this bacterium is cytotoxic to Vero cells. It has been reported that the butyric acid produced by this bacterium induces apoptosis and induces UC-like lesions in mice (Non-Patent Document 5). Furthermore, it has been confirmed that Fusobacterium varium adheres to and invades colonic mucosal cells, and has the effect of significantly promoting the production of inflammatory cytokines such as IL-8 and TNFα from the mucosa (Non-Patent Document 6). Based on the above, it is believed that this bacterium induces inflammation in addition to ulcers, causing ulcerative colitis. It has been reported that when Fusobacterium varium antibody-positive UC patients were administered three antibiotics (amoxicillin, tetracycline, and metronidazole; ATM therapy) that are sensitive to the bacteria in order to eradicate Fusobacterium varium, the symptoms of UC and the endoscopic and histopathological findings improved (Non-Patent Document 7). A similar report was also made in a multi-center, double-blind, placebo-controlled study of over 200 patients (Non-Patent Document 8). Based on the above, Fusobacterium varium is thought to be the causative agent of UC.
[0007] Fusobacterium nucleatum has also been cited as a causative bacterium of CD (Non-Patent Document 3). It has been reported that the bacterium was detected in endoscopic biopsy mucosa of CD in 10 of 17 cases (58.8%), and all of them were invasive (Non-Patent Document 9).
[0008] Fusobacterium nucleatum has also been reported to be associated with esophageal cancer. Specifically, it has been reported that Fusobacterium nucleatum is present in significantly greater amounts in esophageal cancer tissue than in normal esophageal mucosa, that the bacterium is significantly associated with tumor stage, and that a significant relationship between the bacterium and the chemokine CCL20 has been observed, suggesting that the bacterium contributes to the aggressive behavior of tumors through the activation of chemokines such as CCL20 (Non-Patent Document 10).
[0009] Fusobacterium prausnitzii is attracting attention as a probiotic that consumes acetic acid, produces butyric acid, which is beneficial for health, and improves intestinal barrier function. It has been reported that the occupancy level of this bacterium is reduced in both feces and mucosal samples of CD patients and that this bacterium is associated with inflammatory bowel disease (Non-Patent Document 11). It has also been reported that administration of this bacterium to mice has an inhibitory effect on the onset of inflammatory bowel disease (Non-Patent Document 12).
[0010] Streptococcus mutans, a major pathogenic bacterium in dental caries, is known as a causative bacterium of bacteremia and infective endocarditis, but recent research has revealed that it also induces the exacerbation of inflammatory bowel disease. Observation of the abdominal cavity of mice intravenously injected with the bacterium showed signs of enteritis, and administration of the bacterium into the blood of a mouse enteritis model caused the enteritis to worsen. It has been reported that the mechanism behind this is that in strains of the bacterium with a mutation in the surface polysaccharide antigen, this leads to a decrease in phagocytosis by white blood cells, leading to the acquisition of properties that make it difficult to eliminate in the blood for a long time, and that another important factor is that the collagen-binding protein present on the bacterial surface causes the bacterium to localize in liver tissue and be directly taken up by liver parenchymal cells (Non-Patent Document 13). It has been suggested that this promotes the production of cytokines such as IFN-γ, which induces an imbalance in the immune system and induces the exacerbation of inflammatory bowel disease.
[0011] In addition, it has been reported that infective endocarditis caused by Streptococcus bovis is frequently associated with colon cancer (Non-Patent Documents 14-22), and a report has been published suggesting that the presence of bile acids leads to carcinogenesis by promoting colony formation in place of enterococci (Non-Patent Document 22). It has also been suggested that the cell wall extracted antigen (WEA) of the bacterium stimulates the production of IL-8 and COX-2 in Caco-2 cells, which are human colonic epithelial cells, and causes phosphorylation of mitogen activated protein (MAP) kinase, and that the overproduced COX-2 induces cancer induction from a precancerous state through prostaglandin production, cell proliferation, angiogenesis, and apoptosis inhibition (Non-Patent Documents 23-25). It has also been shown that WEA strongly promotes precancerous lesions in azoxymethane-administered mice (Non-Patent Document 26). Furthermore, it has been reported that this bacterium strongly promotes colorectal adenomas to colorectal cancer by inducing NF-κB (Non-Patent Document 27).
[0012] Streptococcus anginosus, which is also detected in endocarditis, is said to be a risk factor for esophageal cancer. It has been reported that the bacterium has been detected in esophageal cancer tissue, and that the risk of esophageal cancer increases by approximately 33 times when Streptococcus anginosus is detected in dental plaque in a comparison between esophageal cancer patients and normal subjects (Non-Patent Document 28).

[0038] Fusobacterium and Streptococcus are known to be pathogens of various diseases. Since the composition of the present invention has an effect of removing Fusobacterium and Streptococcus, the composition of the present invention can be used for treating or preventing diseases caused by Fusobacterium and / or Streptococcus.
[0039] Specifically, the composition of the present invention can be used for the treatment or prevention of colon cancer, inflammatory bowel disease, esophageal cancer, infective endocarditis, bacteremia, periodontal disease, or dental caries. Inflammatory bowel disease to be treated or prevented by the present invention includes ulcerative colitis and Crohn's disease.

[0051] The present invention will be described in more detail below with reference to examples, but the technical scope of the present invention is not limited to the following examples.
[0052] Fecal samples were collected from 34 subjects who had installed an alkaline electrolytic water purifier at home and consumed alkaline electrolytic water daily, and the intestinal flora was analyzed by amplicon sequencing targeting the 16s rDNA partial base sequence. The occupancy rates of Fusobacterium, Streptococcus, and Faecalibacterium in the intestinal flora are shown in Table 1 (data in the "1st" row).
[0053] In addition, based on the analytical data of the intestinal bacterial flora, the 34 subjects were classified into the following enterotypes A to E, as defined by the method described in Non-Patent Document 29.
[0054] <Type A> This type is dominated by Ruminococcus. The genus Streptococcus accounts for the second highest proportion of bacteria after type D. <Type B> A type with a high concentration of Bacteroides. The Faecalibacterium content is higher than Type C, which also has a high concentration of Bacteroides, but not significantly higher than Types A, D, and E. A type with a high concentration of butyric acid bacteria. <Type C> Bacteroides is the most abundant type, and Faecalibacterium is the lowest of the five types. Fusobacterium and Proteus are the highest types. <Type D> This type has a significantly high proportion of Bifidobacterium. It also has the highest proportion of Streptococcus among the five types. <Type E> This type is rich in Prevotella and is the type that has the highest number of healthy individuals out of the five types.
[0055] As a result, of the 34 subjects, 6 were classified as type A, 13 as type B, 5 as type C, 3 as type D, and 7 as type E.
[0056] A total of 34 subjects were asked to drink 1.5 L of the above-mentioned alkaline electrolyzed water with platinum nanoparticles dispersed therein per day for 8 weeks. At the end of the drinking period, fecal samples from the subjects were analyzed, and the intestinal flora was analyzed by amplicon sequencing targeting the 16s rDNA partial base sequence. The occupancy rates of Fusobacterium, Streptococcus, and Faecalibacterium in the intestinal flora are shown in Table 1 (data in the "2nd" row).
[0057] The average particle size of the platinum nanoparticles in the dispersion is 2 nm, and 30 μg of platinum nanoparticles are dispersed in 1.5 L of alkaline electrolyzed water. The average particle size of the platinum nanoparticles is calculated by a model numerical analysis using a small-angle X-ray scattering method.
[0058] Table 1 shows the results of analyzing the intestinal flora of 1,803 subjects randomly selected in advance, and the data on the carrier rate (the proportion of subjects who were carriers of the target bacteria among all subjects) and carrier rate (the average value calculated by calculating the occupancy rate of the target bacteria in the intestinal flora of carriers) of Fusobacterium, Streptococcus, and Faecalibacterium (mother data, M data).The results also show the carrier rate and carrier rate obtained from the first and second analyses, as well as the fluctuation rate (the difference obtained by subtracting the previous carrier rate from the subsequent carrier rate, divided by the previous carrier rate and multiplied by 100).
[0059] [Table 1] *1 The rate of change calculated using the carriage rate obtained in the first analysis as the pre-value and the carriage rate obtained in the second analysis as the post-value. *2 The rate of change calculated using the carriage rate in the mother data as the pre-value and the carriage rate obtained in the second analysis as the post-value.
[0060] The carrier rate of Fusobacterium was 0.43% in the mother data, while it was 0.32% in the first analysis after continued consumption of alkaline electrolyzed water (Table 1). If we assume that the carrier rate of the mother data is the initial value, the results shown in Table 1 indicate that alkaline electrolyzed water has the effect of removing Fusobacterium.
[0061] Furthermore, the carriage rate of Fusobacterium was 0.19% in the second analysis after continued ingestion of alkaline electrolyzed water containing dispersed platinum nanoparticles, and considering that the rate of change was significantly lower at -42.70% between the first and second analyses, the results in Table 1 indicate that platinum nanoparticles are effective in removing Fusobacterium.
[0062] The rate of change in Fusobacterium bacteria was -56.98% in "M data vs. the second time" (Table 1). In addition, in the subject group classified as enterotype type C, which is considered to have a particularly high occupancy rate of Fusobacterium bacteria, a rate of change of -100% was achieved in "M data vs. the second time". These results demonstrate that alkaline electrolyzed water with dispersed platinum nanoparticles has a significantly excellent effect in removing Fusobacterium bacteria.
[0063] The carrier rate of Streptococcus was 3.22% in the mother data, and 1.22% in the first analysis after continued consumption of alkaline electrolyzed water (Table 1). If we assume that the carrier rate of the mother data is the initial value, the results shown in Table 1 indicate that alkaline electrolyzed water is effective in removing Streptococcus.
[0064] Furthermore, the carriage rate of Streptococcus was 0.72% in the second analysis after continued ingestion of alkaline electrolyzed water with dispersed platinum nanoparticles, and considering that the rate of change was significantly lower at -40.59% between the "first and second times," the results in Table 1 indicate that platinum nanoparticles are effective in removing Streptococcus.
[0065] The rate of change for Streptococcus was -77.57% in "M data vs. the second test" (Table 1). In addition, in the subject group classified as type D enterotype, which is considered to have a particularly high occupancy rate of Streptococcus, a rate of change of -96% was achieved in "M data vs. the second test," showing the highest rate of change (removal rate) among all enterotypes. These results demonstrate that alkaline electrolyzed water with dispersed platinum nanoparticles exhibits a remarkably excellent effect in removing Streptococcus.
[0066] Additionally, the carrier rate of Faecalibacterium was 5.80% in the mother data, but was 7.42% in the first analysis after continued consumption of alkaline electrolyzed water (Table 1). If we assume that the carrier rate in the mother data is the initial value, the results shown in Table 1 indicate that alkaline electrolyzed water has the effect of promoting the growth of Faecalibacterium.
[0067] In addition, the carrier rate of Faecalibacterium was 85% in the first analysis after continuous drinking of alkaline electrolyzed water, but increased to 91% in the second analysis after continuous drinking of alkaline electrolyzed water with platinum nanoparticles dispersed (Table 1). This result indicates that platinum nanoparticles have the effect of promoting the growth of Faecalibacterium.
[0068] Considering the result that the fluctuation rate of Faecalibacterium spp. was 23.27% in "M data vs. second time", it was shown that alkaline electrolyzed water with dispersed platinum nanoparticles has a significantly excellent effect of promoting the growth of Faecalibacterium spp.
[0069] From the above results, it can be concluded that the composition of the present invention containing platinum nanoparticles and / or electrolytic water as active ingredients has an excellent effect of removing Fusobacterium and Streptococcus. Furthermore, this test showed that the composition of the present invention has a therapeutic or preventive effect on diseases caused by Fusobacterium or Streptococcus, specifically colon cancer, inflammatory bowel disease, esophageal cancer, infective endocarditis, bacteremia, periodontal disease, or dental caries.
