        • Oral-Intestinal Microbiota in Colorectal Cancer: Inflammation and Immunosuppression (2022)

          • Abstract
            • It is widely recognized that microbial disorders are involved in the pathogenesis of many malignant tumors.
            • The oral and intestinal tract are two of the overriding microbial habitats in the human body. Although they are anatomically and physiologically continuous, belonging to the openings at both ends of the digestive tract, the oral and intestinal microbiome do not cross talk with each other due to a variety of reasons, including
              • intestinal microbial colonization resistance and
              • chemical barriers in the upper digestive tract.
            • However, this balance can be upset in certain circumstances, such as
              • disruption of colonization resistance of gut microbes,
              • intestinal inflammation, and
              • disruption of the digestive tract chemical barrier.
            • Evidence is now accruing to suggest that the oral microbiome can colonize the gut, leading to dysregulation of the gut microbes.
            • Furthermore, the oral-gut microbes create an
              • intestinal inflammatory and
              • immunosuppressive microenvironment
            • conducive to
              • tumorigenesis and
              • progression of colorectal cancer (CRC).
            • Here, we review
              • the oral to intestinal microbial transmission and
              • the inflammatory and immunosuppressive microenvironment, induced by oral-gut axis microbes in the gut.
            • A superior comprehension of the contribution of the oral-intestinal microbes to CRC provides new insights into the prevention and treatment of CRC in the future.

          • Abstract
            • Microbiome is a keystone polymicrobial community that coexist with human body in a beneficial relationship.
            • These microorganisms enable the human body to maintain homeostasis and take part in mechanisms of defense against infection and in the absorption of nutrients.
            • Even though microbiome is involved in physiologic processes that are beneficial to host health, it may also cause serious detrimental issues.
            • Additionally, it has been proven that bacteria can migrate to other human body compartments and colonize them even although significant structural differences with the area of origin exist.
            • Such migrations have been clearly observed when the causes of genesis and progression of colorectal cancer (CRC) have been investigated.
            • It has been demonstrated that the oral microbiome is capable of penetrating into the large intestine and cause impairments leading to dysbiosis and stimulation of cancerogenic processes.
            • The main actors of such events seem to be oral pathogenic bacteria belonging to the red and orange complex (regarding classification of bacteria in the context of periodontal diseases), such as
              • Porphyromonas gingivalis and
              • Fusobacterium nucleatum respectively,
            • which are characterized by significant amount of cancerogenic virulence factors.
            • Further examination of oral microbiome and its impact on CRC may be crucial on early detection of this disease and would allow its use as a precise non-invasive biomarker.

    1. One hundred trillion cells, one and 14 zeros, that's the approximate number of microorganisms in your body, ten times greater than the number of your own cells. Your microbial baggage occupies almost 2% of your body weight, that's about one and a half kilograms, approximately the weight of your liver. Or your brain.

    1. Mayer says time-restricted eating — a form of intermittent fasting that requires you to squeeze all your daily calories into a compressed feeding window — may be helpful. “The migrating motor complex is rarely mentioned in these articles on intermittent fasting, which is surprising because it’s so well-studied,” he says.To ensure the MMC has enough time to perform its duties, aiming for 14 hours without caloric foods or drinks is a good target, he says. For example, you could avoid all calories between 8 p.m. and 10 a.m. “The 14 hours without food intake would allow the MMC to kick in and not only cleanse your gut of any undigestible, unabsorbable food components, but also to reestablish the normal proximal-to-distal gradient of gut microbial density,” he says.

    1. It has long since been demonstrated that Parkinson's patients have a different microbiome in the intestines than healthy people

      Question:

      • In what way is the microbiota different in Parkinson’s disease patients compared to that of healthy people?
      • Do we know anything about the correlation between the particular species of microbiota and the disease?
      • Do we know anything about how the signals being sent from the gut to the brain are different from those in healthy individuals?

    1. in most conceivable cases, we study a particular microbiome in order to understand, predict, and potentially control its functioning, with no particular regard for species content.

      this is profound

    1. 16S sequencing showed that nicotine perturbed bacterial diversity and community composition of gut microbiota more pronouncedly in HFD mice.

      Note that nicotine by itself had minimal impact on the microbiome. Nicotine speeds up transit through the intestine. Thus, the reason nicotine plus a high fat diet was detrimental is likely that nicotine is increasing the throughput of harmful prebiotics (e.g. protein in particular). When lots of fiber and resistant starch is present (will need to see if they provide this info for their diets), then nicotine mostly just carries it to the small intestine faster (and possibly reduces fermentation time).

      Given that opioids have a negative effect on the microbiome, I was expecting nicotine to have a positive effect. Perhaps it would have a positive effect were there more resistant starch in the diet.

    1. Results reveal a significant shift in the gut microbiome and metabolome within one day following morphine treatment compared to that observed after placebo. Morphine-induced gut microbial dysbiosis exhibited distinct characteristic signatures, including significant increase in communities associated with pathogenic function, decrease in communities associated with stress tolerance and significant impairment in bile acids and morphine-3-glucuronide/morphine biotransformation in the gut.

      Unsurprisingly, various substances appear to disrupt the microbiome; artificial sweeteners are not unique. Given that I don't worry about opioids, I probably shouldn't worry about sweeteners.

      However, opioids are known for causing constipation. That is to say, they have a clear effect on digestion. Perhaps I should worry about opioids rather than not worry about sweeteners.

    1. But, if you take a supplement containing 1,250 milligrams, your body seems to realize that’s too much—and so, clamps down on absorption at the intestinal lining level, and you end up absorbing less than half.

      This could be very handy for lowering the pH of the gut (increasing the acidity). As explained in other Greger videos, an acidic gut is desirable because good gut bacteria produce acids and thus are the bacteria that thrive in an acidic environment.

      Currently, I'm taking magnesium citrate. My concern is that the unabsorbed magnesium is alkalinizing my gut. Vitamic C should be able to counteract this (assuming it is indeed an issue). That does make the assumption, however, that the hydrogen ion makes it to the large intestine. That is to say, that the ascorbate does not become a conjugate base.

    1. key challenge is to quantify the functional roles of bacterial taxa in nature to understand how the properties of ecosystems change over time or under different environmental conditions
    2. Hemicellulase activity was elevated in pairwise mixtures of communities that placed interacting phylotypes together (interactions, n = 9 mixtures) but not in communities that did not place interacting phylotypes together (no interactions, n = 56 mixtures)

      Very interesting way to validate correlative phenotypes in communities

    1. I have had IBS essentially all my life. At least as far back as I can remember. This is a very interesting experiement. Hopefully scientists can use this as a springboard for either further research, or ideally, to find a solution. IBS negatively impacts quality of life for many sufferers.

      Isn't the flipped experiment a clear indication that FTT (fecal transplant therapy) can help alleviating IBS? If the reverse is true, there might be great value in getting your microbiome fixed/infused by healthy microbiota from donors.
