In short, our study provides evidence of the E. obliqua anf have adapted to secondary compounds found in tea leaves, and may even benefit from these EGCG and gut health. Our study High-quality coffee beans contributes to a greater understanding of healfh reason abd in plant—insect interactions.
Interactions between gkt plants and herbivorous insects are often mediated by plant secondary compounds, especially an, terpenoids, and phenolics, which are secondary metabolites that are Sugar cravings management among plants 1.

obliqua has been the main focal organism for scientific research due to its economic and ecological importance obliqua larvae consume large quantities of tea leaves in a short period of time and infest thousands of hectares of tea plantations in China annually However, E.
obliqua larvae are susceptible to infection by pathogens, parasites and viruses, a trait that can be exploited for biological control. For example, in agriculture, Beauveria bassiana and E. oblique nucleopoly hedrovirus EoNPV are commonly used to control E. oblique obliqua larvae necessarily ingest large quantities of EGCG during consumption of tea leaves so, here, we investigated the effect of EGCG on gug of E.
obliqua and its reason of action. There were significant differences in the fitness of E. obliqua between the Control and Treatment. Treatment: It is noteworthy that there were no significantly differences in the fitness of E.
obliqua between the Antibiotic and Treatment except index of weight of female pupae. Effects of EGCG on the fitness of E. An unpaired two-tailed t -test was performed to assess the significance of differences between groups unless otherwise stated.
a: weight of male pupa; b: weight of female pupa; c: Eclosion rate. Comparison of survival curves of three larvae groups. Treatment: 2. Treatment: 0. At the genus level, Enterococcus was the dominant genus in the Control For the treatment group, Enterococcus was the dominant genus Enterococcus was dominant in the guts of both the Control and Treatment group and there was no significant difference in dominant bacterial species between the larvae healty the two groups.
There was a large degree of overlap in gut bacterial communities between the two groups, with OTUs shared by the two groups Fig. It is noteworthy that the Pseudomonas in the Control was significantly healrh than that in the Treatment Fig.
Detailed data are shown in the attached table Table S2. Gut bacterial community structure variation of E. Students t test was used to evaluate the significance of differences between two groups.
In the six representative E. obliqua larval gut samples, we obtained a total ofsequences [ Rarefaction curves of the six samples almost reached equilibrium, indicating that the natural bacteria diversity was well represented by the sequencing analysis Fig.
Rarefaction curves of six gut samples based on Hiseq sequencing of E. obliqua larval gut bacterial communities. The PCoA using weighted unifrac distance showed no significant differences in β- diversity of the bacterial communities among larval gut bacteria of the two groups Fig.
In contrast, the PCoA using unweighted unifrac showed statistically significant differences among the two groups Fig. Principal coordinates analysis of differences in gut bacteria of E. a the Principal coordinate analysis PCoA using weighted UniFrac distance; b the Principal coordinate analysis PCoA using unweighted UniFrac distance.
CFU analysis showed a similar result Fig. EGCG treatment reduced the number of culturable bacteria in the gut of E. gu larvae from 2. CFU analysis of difference in cultivable gut bacteria of E. All fitness measures were improved in the Treatment as compared with the Control, indicating that EGCG may have a significant impact on fitness of E.
And there was no significantly difference of all fitness measures except index of female pupae weight between Treatment and Antibiotic, indicating that EGCG promotes the fitness of larvae may be related to the antibacterial function of EGCG. Through observation we found that the Control was more susceptible to bacterial infection and had higher mortality.
Previous study shown that EGCG plays an important role in antibacterial function Therefore, we believe that EGCG improves the fitness of E. obliqua larvae due to its antibacterial function.
Using next generation sequencing technology, we assessed changes in the diversity and richness of ECGG bacterial communities of E. obliqua larvae after EGCG treatment. The EGCG treatment group had significantly lower bacterial species richness and evenness than the control group for three of the four alpha diversity indices.
However, the dominant bacteria of the two groups were similar, and included EnterococcusWeissellaBacteroidesLactococcusSerratiaand Pseudomonas.
These bacteria help to improve nutrient compositions of nutrient-poor host insect diets, aid digestion of difficult to digest food components, protect the host from predators, parasites, and pathogens, and are guut in host mating and reproductive For example, Enterococcus is active throughout the larval life cycle in most Lepidoptera larval guts, and probably plays a key role in insect defense against potentially harmful microorganisms Meanwhile, the phenomenon that gut bacteria promote the fitness of host insects is not unchangeable.
As an example, Pseudomonas of larvae gut of the coffee berry borer beetle Hypothenemus hampei Coleoptera: Curculionidaewhich can help yealth degradation of the caffeine And for other insects, the Pseudomonas is generally considered to be an insect pathogen Therefore, inhibition of colonization gutt Pseudomonas by EGCG in gut may be one of the reasons for promoting larval fitness.
Caterpillars lack a resident gut microbiome and the number of bacteria in the gut of Lepidoptera larvae is much lower than that of other insects or animals And many of bacterial in the gut of caterpillars are transient bacterial, short-lived in the gut of healthy animals, are metabolized in the intestine to produce substances that affect the healthy growth of the host In our study we demonstrated that EGCG could inhibits colonization by many bacterial species e.
Using q-RT-PCR technology and the CFU method, we also assessed changes in the abundance of gut bacteria in E. obliqua larvae guts after EGCG treatment. We found that EGCG treatment can significantly reduce the number of gut bacteria in larvae. In short, we think that one of the reasons why EGCG promotes larval fitness is that it inhibits the colonization of a large number of bacteria in the gut which is confirmed by the results of antibiotic treatment.
Because of longstanding co-evolution, E. obliqua larvae have adapted to secondary compounds found in tea leaves, and may even benefit from these compounds, as is the case for EGCG. Therefore, this study sheds light on one of reasons heslth plant—insect interactions and benefits derived by herbivorous insects, even pests, from their host EGC.
obliqua eggs were obtained from stock cultures from the State Key Laboratory of Tea Plant Biology and Utilization, Anhui Agricultural University, Hefei, China

Otherwise known as the gut microbiota, these organisms are incredibly important for: Helping to create certain vitamins , like vitamin K important for things like bone health and blood clotting , and B vitamins, which are key for energy production, among other things. Interestingly, a study found that individuals on a low vitamin K diet for about a month did not develop K deficiency, but those given a broad-spectrum antibiotic which kills good as well as harmful bacteria did show signs of low K. This just goes to show how important of a role the bacteria within our gut truly hold for their host's overall health aka us! Producing short-chain fatty acids SCFAs : super beneficial for lowering inflammation. Butyrate is likely the most important SCFA of them all, shown to even have anti-cancer effects. Bacterial spores are even more resistant to chemicals, heat, and irradiation than their respective vegetative cells In addition, studies have shown that C. butyricum is resistant to various antibiotics and UV rays Particularly, Clostridium spp. Among the bacterial groups we analysed, Bacteroidetes, Bacteroides , Prevotella , Enterobacteriaceae, E. coli , and Desulfovibrio spp. are gram-negative. Among gram-positive bacteria, Clostridium spp. are the only spore-forming bacteria. Thus, C. butyricum might be relatively more resistant to single UVB irradiation than other bacteria, which leads to relatively high bacterial counts. Some studies also showed that C. butyricum has various uses as an antibacterial agent, in gut epithelial cell proliferation, and in ulcerative colitis therapy 29 , 30 , Unlike in the UV group, short-term supplementation with GTE showed different caecum microbiota modulation patterns including significantly decreased Clostridium cluster IV and Desulfovibrio spp. According to the PCA biplot, the most influential bacteria distinguishing the GU group from the CON group were Lactobacillus spp. and Bifidobacteria Fig. In agreement with previous studies, we observed increased levels of Lactobacillus spp. and Bifidobacterium spp. in human faecal samples upon green tea consumption 1 , 2. Additionally, oral administration of probiotics such as Lactobacillus and Bifidobacterium species was previously shown to have photo-protective effects on UV-exposed skin 32 , 33 , 34 , Furthermore, profound correlations were observed between other skin diseases such as atopic dermatitis and intestinal probiotics 36 , Particularly, colonization of probiotics in the intestine was associated with a decrease in the disease state 36 , The PCA biplot of the CU and CON groups also showed clear discriminant patterns; levels of Lactobacillus spp. and Bifidobacteria were considerably lower in the CU group than levels in the CON group. Overall, these results and results of previous studies suggest that 7-day supplementation with GTE modulates sustained changes in the caecum microbial community, particularly Lactobacillus spp. and Bifidobacteria, and that these changes might prevented UV stress-induced modulation of the microbial community. In metabolomics studies, sample preparation is extremely important because the metabolome composition could be affected by numerous factors, such as time, method of sampling, environment, and how the sample is stored. Before metabolite extraction, accurate sampling and quenching procedures are required to provide a snapshot of the metabolome and determine the repeatability of the experiment To provide exact metabolomics data, samples must be accurately prepared. We observed diverse skin metabolome changes following exposure to UV stress. In the GU group, the opposite metabolic change patterns were observed from those in the UV group, particularly for histidine, tyrosine, trans -urocanic acid, histamine, adenosine, oleic acid, stearic acid, heptadecanoic acid, arachidonic acid, cholesterol, lysoPE , lysoPE , lysoPC , lysoPE , lysoPC , lysoPC , and monoolein Fig. These amino acids, urocanic acid, fatty acids, and lipids are closely related to skin barrier functions. Urocanic acid, which is found in the stratum corneum of the epidermis, plays an important role in protecting the epidermis from UVB-induced damage Free fatty acids are very actively synthesized in the epidermis, but are decreased by acute UV irradiation accompanied by decreased expression of lipid synthesis-related genes 41 , Cholesterol synthesis is also highly related to the recovery of the permeability barrier function of the skin Lysophospholipids are among the most important factors in skin barrier function, skin hydration, and skin inflammation 43 , We also observed significant preventive effects on erythema formation in only the GTE-supplemented group Fig. These differences in preventing erythema formation may be related to the intake level or characteristics of the supplements. According to other reports, both oral administration and topical application of green tea can reduce UVB irradiation-induced erythema in skin i. However, it remains controversial whether erythema formation is inhibited by EGCG administration. Jeon et al. These differences may be related to the different conditions of the experiments such as supplementation amount and period. Reports substantiating the relationship between caffeine or theanine administration and anti-erythema forming effects are lacking. Instead, caffeine was shown to inhibit UV-induced carcinogenesis 8 , 51 , while theanine showed various bioactivities such as neuroprotective, antioxidant, anti-inflammatory effects, and improved immunity Thus, our results showed that 7-day prior supplementation of GTE, rather than single compounds EGCG, caffeine, or theanine , significantly modulated various skin metabolites related to skin barrier function. This modulation inhibited skin metabolome changes according to UV stress, and the effects may help prevent skin erythema formation. On the other hand, no significant differences in MDA and TNF-α levels were observed among groups. MDA is a product of lipid peroxidation which is used as an oxidative stress indicator and TNF-α facilitates the migration of inflammatory cells. According to other animal studies that used similar experimental conditions as those used in our study, similar phenomena were observed in MDA and TNF-α measurements. Svobodova et al. Sharma et al. Overall, results of our study and previous studies showed that the levels of MDA and TNF-α in mouse skin were induced by UVB irradiation, but results were highly influenced by irradiation conditions such as dose, distance from device, and the amount of time passed after exposure. The relationship between the gut and skin was previously not well-understood. Microbial compounds including cell wall fragments, dead cells, and microbial metabolites may induce immune responses that improve skin health Endogenous caecum metabolite profiling was performed to evaluate the relationship between the caecum microbiota and endogenous skin metabolites. According to the heatmap of the caecum metabolome, a few metabolites were significantly altered by UV stress. However, short-term supplementation with GTE, EGCG, caffeine, or theanine induced more diverse metabolite modulations in the caecum Fig. This may be because diet is a crucial factor affecting the composition of the intestinal microbiota, and thus each compound influenced the host in a different manner According to the heat map, bile acid levels were much higher in all treatment groups than in the CON group. Bile acids are well-known gut bacteria metabolites with various biological functions including absorbing lipid-soluble vitamins; facilitating lipid absorption; maintaining intestinal barrier function; and regulating triglyceride, cholesterol, glucose, and energy homeostasis Bacteria including Bacteroides , Clostridium , Lactobacillus , Bifidobacterium , Enterobacter , and Eubacterium are associated with bile acid metabolism These highly increased bile acids levels may be related to UV stress. In the GU group, levels of several metabolites such as glutamine, 5-oxoproline, myo -inositol, glucose, glycerol, oleic acid, palmitic acid, and stearic acid were altered. These metabolites showed a high correlation with the caecum probiotic bacteria Lactobacillus spp. and Bifidobacteria. Thus, modulation of the Lactobacillus spp. and Bifidobacteria populations and the effects of GTE supplementation on mice intestine appear to be closely related. These relationships may affect erythema formation in the skin. In conclusion, we conducted comprehensive metabolome analysis to elucidate the effects of short-term 7-day supplementation of dietary components on modulating the gut and endogenous metabolomes. Among the supplements examined, including GTE, EGCG, caffeine, and theanine, only short-term supplementation with GTE remarkably modulated the microbiome-metabolome accompanied with significant prevention of UV stress in mice. Particularly, probiotics including Bifidobacteria and Lactobacillus spp. were highly associated with GTE supplementation and bacteria levels were highly correlated with skin barrier function-related metabolites.

| Green Tea Extract May Help Reduce Blood Sugar and Gut Inflammation | For each representative sequence, the RDP classifier Version 2. To study phylogenetic relationships among the OTUs and compare dominant species in different samples groups , multiple sequence alignment was conducted using MUSCLE software Version 3. Abundance values of OTUs were normalized using a standard of sequence number corresponding to the sample with the least sequences. Subsequent analysis of alpha diversity and beta diversity were performed using this normalized output. Rarefaction curves were generated based on observed species richness. Beta diversity analysis was used to evaluate differences in species complexity among the two groups. Beta diversity of both weighted and unweighted unifrac were calculated using QIIME software Version 1. Principal Coordinate Analysis PCoA was performed to visualize the gut bacteria species complex, and to illustrate the differences in the larval gut bacterial community composition and structure on the unifrac distances of the unweighted and weighted distance matrices, respectively. To determine which of the gut bacterial community could form colonies, we first extracted whole larval guts under sterile condition, as described previously. In order to verify the antibacterial function of EGCG. The strain was grown in Luria Broth LB medium, adjusted to an optical density OD of 0. We then calculated the number of gut bacteria using the CFU method. Nakayama, M. et al. Mechanism for the antibacterial action of epigallocatechin gallate egcg on bacillus subtilis.
