Botanical Mixture Stabilizes Cognitive Function in Patients with Mild and Moderate Alzheimer’s Disease

August 17, 2018

Abstract

Context: Currently, there is no treatment that can stop the progression of Alzheimer’s disease. We have used transgenic Drosophila melanogaster models and machine learning to develop an eight component botanical mixture (Geneaire™ ReBuilder™) that targets multiple genetic pathways involved in brain aging and dementia that are homologous between Drosophila and humans.

Objective: To test the effects of ReBuilder on the cognitive function of subjects diagnosed with mild or moderate Alzheimer’s disease.

Methods: We recruited 50 subjects with mild to moderate AD to participate in a double-blind, placebo-controlled clinical study. During the 12-month pilot study, the subjects were evaluated quarterly on the Mini Mental State Exam (MMSE), Alzheimer’s Disease Cooperative Study’s Activities of Daily Living (ADCS-ADL), and the Clinical Dementia Rating Sum of Boxes (CDR-SB).

Results: The addition of ReBuilder to subjects’ existing Namenda and Exelon regimens stabilized cognitive decline in patients with mild AD and slowed cognitive decline in patients with moderate AD.

Conclusions: These results were observed in both sexes and in all ages tested. Importantly, no adverse side effects attributable to ReBuilder were reported. The results of this clinical pilot warrant further study of ReBuilder in AD.

Multipath Natural Product Supplement Suppresses Dementia Symptoms in Amyloid-β and Tau Transgenic Drosophila

January 18, 2018

Abstract

Background: Numerous reports on Alzheimer’s Disease (AD) indicate that AD has many biochemical pathways. However, most AD treatments have targeted a single pathway such as beta amyloid or phosphorylated tau and have not been very successful in stopping AD progression. To address the multipath nature of AD, we have used multiple natural products that target critical aging and independent AD pathways to test whether a multipath approach might be more effective than the single pathway approaches typically used.

Methods and findings: We have constructed Drosophila melanogaster models of AD with inducible transgenic human Amyloid-β and tau mutations. Induction of either AD mutant gene in the transgenic flies after emergence from pupal stage leads to the early onset of slowed mobility that was tracked by assaying crawl times as a function of age. The transgenic Amyloid-β and tau Drosophila assays were utilized to test various natural products that target separate biological pathways involved in brain aging and dementia. Screening a library of natural products, we identified a group of 7 natural substances (MX100A) that synergistically prevented nearly all early mobility difficulties and reverses the lifeshortening effects of Amyloid-β and tau. The favorable results on AD symptoms in Drosophila with MX100A were observed in animals treated from youth and from later adult ages. MX100A had no observed negative side effects.

Conclusion: Treatment of transgenic AD Drosophila with the multipath MX100A dietary supplement prevents nearly all early mobility difficulties and reverses the lifeshortening effects of Amyloid-β and tau. In patients with AD, progressively more severe mobility difficulties and heightened risks of mortality are common symptoms of the later stages of AD. While successful animal results have not typically translated into effective treatments for AD, the multipath MX100A treatment results are promising enough to warrant further testing.

Laboratory Summary Report: 2017

Winter Quarter

  1. Work continues on a paper that describes our transgenic Alzheimer’s fly model and the human pilot study we conducted as a result of studies using that model.
  2. Some preliminary data analysis of the MX100a patient registry, which has grown to over 150 individuals, shows that the human pilot results are in fact being replicated, and patients’ cognitive and functional test scores are stable, or improving.
  3. NOTE: The registry data is not a controlled trial, and can only be looked at in terms of trends.

Spring, Summer Quarters

  1. Wrapping up our paper describing our transgenic Alzheimer’s fly model and the resulting human pilot study.

Fall Quarter

  1. After Thanksgiving, we decided to divide the paper into two separate papers: a paper describing our transgenic Alzheimer’s fly model, and a paper describing the human pilot testing our formulation.
  2. The transgenic fly paper is submitted to the Journal of Biology and Medical Research in December.

Laboratory Summary Report: 2016

Winter Quarter

  1. Our Gen31 experiment assays the transgenic Tau Alzheimer’s Disease (AD) flies and our “B” flies with MX100a, memantine (Namenda), and combinations of the two therapies.
  2. Memantine (Namenda), is one of only a few “first line” therapies used to treat AD. Genescient made the decision to test memantine using our fly model to validate the model and verify our results to date.
  3. We observed that memantine did indeed reduce symptoms in our transgenic Tau flies, thus helping to validate our platform for testing of AD treatments.
  4. We saw the most positive results with the co-therapy of MX100a and memantine, suggesting a possible synergistic effect, and a possible avenue for us to explore potential collaborations.
  5. Genescient enlists te help of Bob Cruise, Ph.D., to help with our analysis of the human pilot data.
  6. We find that Memex seemed to help people with the ApoE4 genotype associated with the onset of AD.

Spring Quarter

  1. During our continued analysis of the human pilot data, we compare our data to a study titled “Age and Rate of Cognitive Decline in Alzheimer Disease” by Charles Bernick, et. al., that analyzed 471 AD patients “mild to moderate AD assigned to the placebo arm of 3 clinical trials.”
  2. Our patient trajectories are positive compared to the placebos in the Bernick paper, suggesting that MX100a has a positive effect on AD patients.

Fall and Winter Quarter

  1. The MX100a patient registry has continued to grow to over 200 participants.
  2. The patients appear to be stabilizing, and Dr. Shankle continues to recommend MX100a to all of his patients.
  3. At this time, it’s the further fortified MX100a+ that the patients are taking.
  4. Genescient begins work on a paper to report our results with the transgenic AD flies and subsequent human pilot study.

Genome-wide analysis of long-term evolutionary domestication in Drosophila melanogaster

December 22, 2016

Abstract

Experimental evolutionary genomics now allows biologists to test fundamental theories concerning the genetic basis of adaptation. We have conducted one of the longest laboratory evolution experiments with any sexually-reproducing metazoan, Drosophila melanogaster. We used next-generation resequencing data from this experiment to examine genome-wide patterns of genetic variation over an evolutionary time-scale that approaches 1,000 generations. We also compared measures of variation within and differentiation between our populations to simulations based on a variety of evolutionary scenarios. Our analysis yielded no clear evidence of hard selective sweeps, whereby natural selection acts to increase the frequency of a newly-arising mutation in a population until it becomes fixed. We do find evidence for selection acting on standing genetic variation, as independent replicate populations exhibit similar population-genetic dynamics, without obvious fixation of candidate alleles under selection. A hidden-Markov model test for selection also found widespread evidence for selection. We found more genetic variation genome-wide, and less differentiation between replicate populations genome-wide, than arose in any of our simulated evolutionary scenarios.

Herbal Supplement Extends Life Span Under Some Environmental Conditions

April 16, 2015

Abstract

Genetic studies indicate that aging is modulated by a great number of genetic pathways. We have used Drosophila longevity and stress assays to test a multipath intervention strategy. To carry out this strategy, we supplemented the flies with herbal extracts (SC100) that are predicted to modulate the expression of many genes involved in aging and stress resistance, such as mTOR, NOS, NF-KappaB, and VEGF. When flies were housed in large cages with SC100 added, daily mortality rates of both male and female flies were greatly diminished in mid to late life. Surprisingly, SC100 also stabilized midlife mortality rate increases so as to extend the maximum life span substantially beyond the limits previously reported for D. melanogaster. Under these conditions, SC100 also promoted robust resistance to partial starvation stress and to heat stress. Fertility was the same initially in both treated and control flies, but it became significantly higher in treated flies at older ages as the fertility of control flies declined. Mean and maximum life spans of flies in vials at the same test site were also extended by SC100, but the life spans were short in absolute terms. In contrast, at an independent test site where stress was minimized, the flies exhibited much longer mean life spans, but the survival curves became highly rectangular and the effects of SC100 on both mean and maximum life spans declined greatly or were abolished. The data indicate that SC100 is a novel herbal mix with striking effects on enhancing Drosophila stress resistance and life span in some environments, while minimizing mid to late life mortality rates. They also show that the environment and other factors can have transformative effects on both the length and distribution of survivorship, and on the ability of SC100 to extend the life span.

Flying in the face of aging

December 16, 2013

The Methuselah fruit fly lives for about four months – four times longer than an ordinary fruit fly.

They’re also more vigorous. “They beat up the other flies and take their women away,” said Gregory Benford, a retired UC Irvine physics professor.

Benford, 72, is co-founder of Genescient Corp., a Fountain Valley research and development company that studies fruit flies to learn how to slow human aging and aging-related diseases, such as Alzheimer’s.

Laboratory Summary Report: 2012

Winter Quarter

  1. Dr. Robin Mockett, at University of Alabama, confirmed the longevity benefits of MX-100 on his fruit flies under certain conditions.
  2. We begin writing the MX-100 paper, reporting these longevity results, with the goal of submitting to Plos One.
  3. The Genescient Lab begins planning transgenic fly experiments with the 9 genes that we think make the O Flies live so long, according to our AI analysis. We also plan on testing the transgenic AD flies.
  4. Preliminary testing is done to sort out the crawl test procedure and induction of A-beta in transgenic AD flies using RU486 (Mifpristone).
  5. Dr. John Tower of USC has told us that other transgenic flies, ie with our longevity genes, should also be inducible with RU4486.

Spring Quarter

  1. We have acquired, increased numbers, and maintained our targeted transgenic fly lines: 9 “O” longevity genes, transgenic AD flies carrying Tau, and transgenic AD flies carrying Abeta.
  2. A new stress test is planned (on B flies) testing substances known in literature to act on the “O” genes.
  3. Our preliminary AD fly crawling assays show that selenium, genestein (low and high dose), lithium, HCTZ, tretinoin, silymarin, and MX-100 all mitigate AD symptoms in transgenic flies with ABeta and Tau genes.

Summer Quarter

  1. Our Gen18 stress test assays 13 new substances and compares them to the effects of MX-100.
  2. The goal of Gen18 is to decide what should be added to MX-100 to make a novel and effective AD treatment to test using the transgenic AD fly model.
  3. These results are another proof of concept for Ben Goertzel’s AI selection techniques, as the substances selected seem to be successful.
  4. Our Gen19 experiment is a replicate of Dr. Robin Mockett’s protocol with MX-100, and we plan to include the results in the Plos One paper. Dr. Mockett’s protocol has flies living in vials instead of cages, and separated by sex. We are able to replicate his results: fly longevity is extended greatly in sex separated vials treated with MX-100.

Fall Quarter

  1. Our Gen20 experiment tests the effects of RU induction on our 9 “O” longevity genes. If the genes are properly induced, the flies should live longer.
  2. We find 2 out of the 9 genes significantly increase longevity when induced with RU, a “good” discovery rate using our machine learning and AI methods.
  3. Our Gen21 experiment is a stress test assaying MX-100, individual components of MX-100, synthetic versions of components of MX-100, and some different combinations of the natural and synthetic components. The MX-100 formulation is still the best performing.
  4. Our Gen22 experiment is another stress test assaying more substances and combinations based on Gen21. MX-100 and the other best performing combinations are to be tested using the transgenic AD fly model.

Laboratory Summary Report: 2011

Winter Quarter

  1. We collected the remaining O flies (“RO”) from the Rose lab at UCI, and Genescient now houses ALL O flies.
  2. In our Gen9 experiment, we tested MX-100 again. This time, we included a cohort of flies that didn’t get the treatment until mid-life. The reasoning behind this was to simulate what it might look like if someone in their 50’s started taking MX-100, as opposed to someone that started from youth, which has been the standard model of our fly experiments.
  3. MX-100 extended lifespan in all treatment groups by about 50%, including the delayed treatment group.

Spring Quarter

  1. To check for normal reproductive function in the flies, we performed a fecundity assay with MX-100 treated flies. No negative fecundity effects were observed, and female egg production was normal.
  2. Genescient has decided to shift the focus of our research from cardiology and septic shock to Alzheimer’s Disease (AD).
  3. We will use a crawling assay developed by Linda Partridge at University College London using a transgenic AD fly model to screen substances that attenuates the impaired movement of the flies.
  4. We will start testing MX-100 and other neuro-protective supplements on these transgenic AD flies.

Summer Quarter

  1. In the Genescient Lab, we developed a technique for rapid substance screening using starvation as a means of inducing stress in the flies.
  2. This new assay will help us screen substances that help the flies mitigate this stress and live longer, but on a shorter time scale.
  3. Our Gen10 experiment uses this new technique, and tests MX-100, as well as 3 reportedly neuro-protective substances: horny goat weed, milk thistle, and PQQ.
  4. In this first stress test, we starved the flies using only agar treated with substances. The flies died off within a week, but MX-100 was the most “protective” followed by PQQ.
  5. We decided to use MX-100 and PQQ in the next experiment, but using 10% and 20% of normal banana food treated with substances, rather than starving the flies outright.
  6. Our Gen11 stress experiment shows that 10% of food is the optimal amount that still shows enough separation in survivorship trajectories, and also mirrors “normal” trajectories, but on a shorter (faster) scale.
  7. MX-100 and PQQ performed about equally in Gen11.
  8. aOur Gen12 experiment used the stress assay with B and O flies, testing MX-100, PQQ, alone and in combination.
  9. During this Gen12, there was an extreme heat wave, and we didn’t yet have incubators in the lab. The heat added another element of stress and caused more rapid deaths, especially for the B flies. We were able to observe some stress resistance provided by the supplements, especially the combination of MX-100 and PQQ.
  10. Our Gen13 experiment used the stress test to assay varying doses of Rebuilder and Milk Thistle.
  11. Another heat wave was experienced during Gen13, but it appeared that the low dose of MX-100 and medium dose of Milk Thistle were most effective at maintaining survival.
  12. Our Gen14 experiment used the stress test to assay Milk Thistle and PQQ alone and in combination.
  13. PQQ alone, and combined with Milk Thistle, gave the best stress resistance in Gen14.
  14. Our Gen15 experiment was our first large-scale stress test, assaying 13 different substances, including 2 forms of MX-100.
  15. The most successful substances in the Gen15 experiment were MX-100a, selenium, low dose Genistein, and lithium.
  16. In September, we moved to new lab location in Huntington Beach. We also purchased incubators for flies to help with temperature control during experiments.

Fall Quarter

  1. Discussions began about ordering transgenic flies with 9 genes of interest, as well as AD genes.
  2. Ben Goertzel submitted his report on the genetic analysis of O and B flies, distinguishing different genes that contribute to “O-ness.”
  3. We begin to work with John Tower at USC about AD flies and experimental design ideas such as the crawl tests.
  4. Our Gen16 experiment uses the stress test to assay MX-100a, varying doses of lithium, and silymarin. MX-100a + 5mg lithium was the most successful for stress resistance.
  5. Our Gen17 experiment uses the stress test to assay MX-100a, BioPQQ, Genestein, Trentinoin, Coumarin in varying doses and combinations. MX-100a was still the most successful.
