Title: Blood glucose control and anti-obesity probiotics compositions in a specific selection and ratio

Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     The present invention claims priority to the U.S. provisional patent application Ser. No. 63/135,578, titled “ANTI-OBESITY PROBIOTICS COMPOSITIONS IN A SPECIFIC SELECTION AND RATIO,” filed on Jan. 9, 2021, which is incorporated by reference in its entirety for all purposes. 
    
    
     FIELD OF INVENTION 
     The present invention relates to blood glucose control and anti-obesity human probiotics compositions. Particularly, the present invention relates to one or more preselected combinations and specific ranges of ratios of blood glucose control and anti-obesity human probiotics compositions and their preparation methods and uses. 
     BACKGROUND OF THE INVENTION 
     Obesity is now a plague in developed countries as well as in many developing countries. Since obesity increases the risk of many health conditions, including cardiovascular disease, stroke, type 2 diabetes, fatty liver and certain cancers, it is important to understand the detailed mechanism of obesity development and search for novel ways to treat obesity. 
     Dual-specificity phosphatases (DUSPs) are canonically characterized as negative regulators of the mitogen-activated protein kinase (MAPK) pathway. Some studies have demonstrated that DUSP6, also known as MKP-3, negatively regulates ERK1/2 activity via dephosphorylation, although this dephosphorylation activity could be context-dependent. Dusp6-deficient mice have been shown to have enlarged hearts and an increased resistance to some heart diseases. It has been reported that Dusp6 is upregulated in the liver of obese and diabetic mice and promotes glucose output in both cultured liver cells and mouse livers. Furthermore, it has been shown that systemic Dusp6 deficiency could significantly decrease blood glucose levels, improve insulin sensitivity and increase the resistance to diet-induced obesity (DIO). Besides host genetic and environmental factors, the gut microbiota has been recognized as a major regulator in the development of obesity. However, whether or not dusp6-deficiency-mediated effects on obesity function via the gut microbiota remains unclear. 
     To decrease the risk from obesity and control the blood glucose, a method to treat or prevent obesity, or controlling the blood glucose is needed. 
     SUMMARY OF THE INVENTION 
     For at least the above-mentioned purpose, one or more predetermined combinations of human (e.g., including animals) probiotics and specific ranges of ratio of anti-obesity human probiotics compositions and their preparation methods and uses are provided. Particularly, the present disclosure provides a specific composition of food-grade probiotics been shaped by germ-free or antibiotics-treated dual-specificity phosphatase 6 (Dusp6) deficient mammal, which is effective in altering a relative abundance of gut microbiota and also useful in reducing body weight, fat mass, and/or size of adipocytes and increasing oxygen consumption and/or energy expenditure and thus can be used to treat or prevent obesity or its associated metabolic disorders or conditions in a subject in need. The present disclosure also provides methods and compositions for stabilizing blood glucose levels, reducing blood glucose level spiking (e.g., within two hours of food consumption), and/or preventing blood glucose level fluctuation.

     DETAILED DESCRIPTION OF THE INVENTION 
     The present disclosure is based on the unexpected results that gut microbiota collected from a dual-specificity phosphatase 6 (Dusp6) deficient mammal, when administrated into a subject, can change relevant abundance of microbiota in a gastrointestinal tract of the subject. The present disclosure also provides that the gut microbiota collected from a Dusp6 deficient mammal exhibit anti-obesity activities under high-fat diet, which are effective in reducing of body weight, fat mass, and/or size of adipocytes and increasing oxygen consumption and/or energy expenditure, and thus can be used to treat obesity or its associated disorders or conditions in a subject in need. The present disclosure also provides a platform technology to obtain a combination of 6 food grade bacterial probiotics with specific ratio by using a Dusp6 deficient mammal therefrom for treatment/prevention of obesity or its associated disorders or conditions. 
       FIG. 1  illustrates a probiotic microbiota obtaining method  100  in accordance with some embodiments. At a Step  102 , a germ-free or antibiotics-treated Dusp6 deficient mammal is provided. At a Step  104 , a selected group of microorganisms are administrated to the germ-free or antibiotics-treated Dusp6 deficient mammal. In one embodiment, 6 food grade bacterial probiotics (in equal amounts of colony-forming units) are orally administrated into a germ-free Dusp6 deficient mammal. The 6 food grade bacterial probiotics include 1)  Bifidobacterium breve;  2)  Bifidobacterium longum;  3)  Streptococcus salivarius  subsp.  thermophiles;  4)  Lactobacillus acidophilus;  5)  Lactobacillus casei ; and 6)  Lactobacillus delbrueckii.    
     At a Step  106 , gut microbiota from the Dusp6 deficient mammal are collected. 
     At a Step  107 , the collected gut microbiota are placed on a diet induced obesity model. 
     At a Step  108 , specific abundance ratios of these 6 food-grade bacterial probiotics mixture shaped by Dusp6 deficient mammal is identified. At a Step  110 , an anti-obesity/glucose stabilizing probiotics mixture by the identified ratios is reconstituted. At a Step  112 , additives are added to form a human/animal probiotic product. 
     Experimental Section for Mice Treatment 
       FIG. 2  illustrates a diagram showing the time progress of the probiotic microbiota obtaining method in accordance with embodiments of the present disclosure. 
     In some embodiments, groups of 4 weeks old 8 wild type mice and 7 Dusp6-deficient mice (D6KO) are used. In some embodiments, the full dose of Abx is comprised with antibiotics water (ampicillin 100 mg/kg of mouse weight, metronidazole 100 mg/kg of mouse weight, vancomycin 50 mg/kg of mouse weight, neomycin 100 mg/kg of mouse weight) for native gut microbiota depletion. The mice are initially treated with first stage Abx (antibiotics treatment), which comprises oral gavage full dose Abx 200 uL every day and ¼ dose Abx in drinking water for 5 days (begins at −T3). Then, the second stage Abx treatment changes to full dose Abx water intake (replaced every 3˜4 days) for 11 days (until −T1). The Abx treatment removes most of the microbiota in a gastrointestinal tract to obtain gut-microbiota-depleted mice. The Abx treatment here is merely one of choices to remove native microbiota in a gastrointestinal tract, the disclosure is not limited thereof. Any possible method to create gut-microbiota-depleted mice is able to be used. 
     Probiotics Mixture Preparation 
     The mixture of the probiotics are able to be prepared having the amount as show in table 1.

     The probiotics intake begins at −T1, which comprises oral gavage mix-probiotics 300 uL 3 times/week for 2 weeks. Then all mice are treated with probiotics mix including  Bifidobacterium breve  (e.g.,  Bifidobacterium breve  BR18),  Bifidobacterium longum  (e.g.,  Bifidobacterium longum  BL986),  Lactobacillus acidophilus  (e.g.,  Lactobacillus acidophilus  LA1063),  Lactobacillus casei  (e.g.,  Lactobacillus casei  LC122),  Lactobacillus delbrueckii  subsp.  lactis  (e.g.,  Lactobacillus delbrueckii  subsp.  lactis  LDL114) and  Streptococcus thermophilus  (e.g.,  Streptococcus thermophilus  ST37) in only one dosage of equal ratio, the 45% calories fat HFD treatment (high-fat diet treatment) begins at T0 for 10 weeks. The HFD treatment is used to perform diet-induced obesity. 
     Observation and Collection 
     The body weights of the mice are observed at day −22, −18, −14, −11, −7, and about once/week from day 0 to day 71. Also, the fecal collections are performed at day −22, −14, −11, −7, 0, 14, 21, 28 and 71. 
     Glucose tolerance test is also performed at T9, which comprises intraperitoneal injection 2 g/kg glucose to mice, and measure blood glucose level at before and 15, 30, 45, 60, 90, and 120 min after glucose injection. 
     Results 
     See  FIG. 3 .  FIG. 3  illustrates the result of change of Lee index, BMI and organ weight of the wild type mice and D6KO mice before and after the method  100  of  FIG. 1 . 
     The estimation of body fat may be calculated by Lee index and BMI of the mice. 
     Both Lee index and BMI of the D6KO mice are statistically significantly lower than the wild-type mice after a 10 weeks high-fat-diet treatment. The result is further supported by our experiments showing that the microbiota in D6KO is able to attenuate the high-fat-diet-induced weight gain in wildtype mice (Nat Microbiol. 2016 Nov. 28; 2:16220. doi: 10.1038/nmicrobiol.2016.220.), which is incorporated by reference for all purposes. 
     Organ Weights 
     The epididymal white adipose tissue (EWAT) of the D6KO mice are statistically significantly lower in weight than the wild-type mice after a 10 weeks high-fat-diet treatment. 
     Diversity and Abundance of Intestinal Microbiota 
     See  FIGS. 4 and 5 ,  FIG. 4  illustrates the abundance of the intestinal bacteria of wild type and D6KO mice at T0 and T10.  FIG. 5  illustrates the Non-metric Multidimensional Scaling of the intestinal bacteria of wild type and D6KO mice at T0 and T10. 
     Effective richness, Shannon index and beta-diversity NMDS are calculated by Rhea (V1.6) R pipeline. 
     The data of the intestinal bacteria of wild type and D6KO mice at T0 and T10 performs NMDS, using Bray-Curtis distance for calculation and the number of verification replacements is 999. 
     As the result, the richness and alpha-diversity of D6KO mice gut microbiome is greater than wild type mice. A moderate degree to profound gut microbiome dysbiosis is associated with obesity and metabolic disorders such as type-2 diabetes. The increase of gut microbiome richness and alpha-diversity is in general linked to an overall better health condition. 
     The Dusp6-deficient mice are resistant to diet-induced obesity. The fecal microbiota transplant experiments in germ-free mouse models showed that the gut microbiota contribute substantially to the diet-induced-obesity-resistant phenotype in Dusp6 knockout mice. 
     Abundance of the Six Probiotics Mixture Treatments 
     Based on the results described above, D6KO mice are still more resistant to diet-induced obesity even their native gut microbiota is replaced to 6-probiotics mix. It is shown that D6KO mice and wild type mice with the 6-probiotics mix are more resistant to diet-induced obesity and have better results in blood glucose control. 
     The relative ratios of the 6 food grade bacterial probiotics ((1)  Bifidobacterium breve;  2)  Bifidobacterium longum;  3)  Streptococcus salivarius  subsp.  thermophiles;  4)  Lactobacillus acidophilus;  5)  Lactobacillus casei ; and 6)  Lactobacillus delbrueckii ) in oral gavage to wild-type mic and D6KO mice are in a ratio of 1:1:1:1:1:1.

     Intraperitoneal Glucose Tolerance Test (IP-GTT) 
     In another embodiment, 8 mice are prepared for each of the control group and the treatment group. The 8 mice are germ-free mice. Gavage of the control group mice is provided with ddH 2 O (300 uL/time, 3 times/week) and fed with HFD, and gavage of the treatment mice is provided with 1% Betaine+200 mg/kg CAMU CAMU+1.0×109 CFU/per probiotics of the 6 food grade probiotics, and fed with HFD. 
     The IP-GTT test is performed at 6 th  week of high-fat-det treatment. The process of the IP-GTT test is as follow. Mice were fasted for 12 hours with free access to water, and intraperitoneally injected with glucose at a dose of 2 g per kg body weight. Blood glucose level was measured with a glucometer (Johnson &amp; Johnson) immediately before and 15, 30, 45, 60, 90 and 120 min after glucose injection. In the GTT response plot, the y-axis is the blood glucose concentration and the x-axis is the time that the blood glucose was measured. In the AUC plot, the y-axis means the The Area Under the Curve (AUC) derived from the IP-GTT by calculating the incremental Area Under Curve (AUC) is developed is used to compare the impaired glucose tolerance levels in different groups of mice. The Y-axis is the arbitrary unit of Area Under Curve and the X-axis is the different groups of mice. 
     See  FIG. 6 ,  FIG. 6  illustrates a diagram of the IP-Glucose Tolerance Test (GTT)(mg/dL) at 6 th  week. 
     As shown in  FIG. 6 , the glucose tolerance of the treated mice is 8% better than the control group. The result shows that the mice treated with 1% Betaine+200 mg/kg CAMU CAMU+1.0×109 CFU/per probiotics of the 6 food grade probiotics may have higher tolerance to the change of blood glucose level. 
     Since the probiotics may help controlling the blood glucose level, it may be administered at a) after detecting a spike in blood sugar, b) daily life (e.g., as daily use supplement), or to c) pregnant women and other people who cannot use insulin. 
     In some embodiments, the probiotics may be applied with effective dose about 1-100 billion CFU/day. Preferably, the probiotics may be applied with 10-50 billion CFU/day. More preferably, the probiotics may be applied with 30 billion CFU/day. 
     In some embodiments, the 6 food grade bacterial probiotics ((1)  Bifidobacterium breve;  2)  Bifidobacterium longum;  3)  Streptococcus salivarius  subsp.  thermophiles;  4)  Lactobacillus acidophilus;  5)  Lactobacillus casei ; and 6)  Lactobacillus delbrueckii ) are in a ratio of 1:1:1:1:1:1. 
     In a high-fat-diet induced obesity mouse model with wild-type mice, the administration of 6-probiotics mix ((1)  Bifidobacterium breve;  2)  Bifidobacterium longum;  3)  Streptococcus salivarius  subsp.  thermophiles;  4)  Lactobacillus acidophilus;  5)  Lactobacillus casei ; and 6)  Lactobacillus delbrueckii  in a 1:1:1:1:1:1:1 ratio) with Camu Camu and Betaine for 6-weeks enhances ˜8% of the glucose homeostasis based on glucose tolerance test. 
     In contrast, it is reported that a typical combination or individual species of  Lactobacillus acidophilus  and  Bifidobacterium longum  alone do not show any effect on glucose homeostasis (Biochem Biophys Res Commun 2016 Nov. 11; 480(2):222-227. doi: 10.1016/j.bbrc.2016.10.031.). 
     Similarly, typical  Lactobacillus delbrueckii  administration by itself in a genetic type-2-diabetic mouse model has shown no effect on glucose homeostasis (J Clin Biochem Nutr. 2012 September; 51(2):96-101. doi: 10.3164/jcbn.11-07.). 
     In some embodiments, the combination of the 6 food-grade bacterial probiotics has at least selected 1, 2, 3, 4, or 5 of the 6 probiotics that is 10 times, 100 times or 1000 times more than the rest of probiotics. 
     In some embodiments, the 6 food-grade bacterial probiotics ((1)  Bifidobacterium breve;  2)  Bifidobacterium longum;  3)  Streptococcus salivarius  subsp.  thermophiles;  4)  Lactobacillus acidophilus;  5)  Lactobacillus casei ; and 6)  Lactobacillus delbrueckii ) are in a ratio of 10:10:1:10:10:1. 
     Method for Determining the Ratio of the Probiotics is qPCR Analysis Using General 16S rRNA Sequence as a Reference to Calculate the Relative Abundance. 
     In some embodiments, the method further comprises measuring the 6 food-grade bacterial probiotics mixture&#39;s anti-obesity activity in a subject. 
     In some embodiments, the 6 food-grade bacterial probiotics mixture are identified by measuring whether the microbes are effective in reducing body weight, fat mass, inducing ucp-1 browning gene expression and/or size of adipocytes in a subject upon administration of the microbes. 
     In some embodiments, the 6 food-grade bacterial probiotics mixture are identified by measuring whether the microbes are effective in increasing oxygen consumption and/or energy expenditure in a subject upon administration of the microbes.
