  • This talk was given at a local TEDx event, produced independently of the TED conferences.
    Because we want to understand what genes are required for blood vessel development, Courtney Griffin studies certain enzymes that help turn genes on and off. These enzymes are specifically involved in relaxing DNA that is normally tightly coiled up in our cells.

    Epigenetics. Your genes are not set in stone. You don't have to live with the fact that just because your parents or grandparents were unhealthy doesn't mean you have no other choice but to be unhealthy also. You can change particular genes in your body just by eating the right foods and getting rid of the toxic bad habits, of any kind, and reprogramming your cells to make your body much healthier and stronger. By also applying an exercise routine that will decrease stress is also key to fixing your genes. Epigenetics is a new science that is telling us that we can take control of our bodies destiny and make it so healthy that our longevity will stamp out diseases and we can live a happier, healthier, more rewarding long life. If you have never heard about epigenetics, you really should get your knowledge on about these wonderfully new ground breaking science. The facts are clear and we truly do have control over how our lives are lived.

      Wrong. You cant change your genes. You can, just sometimes change the expression of your genes! Often Epigenetic factors like DNA-Methylations are even not reversible

      Hope is right! The wonderful thing is that we can "repent" (change our ways) to break the curses passed on. While the sins of the father may be passed to the next generation, the next generation can change their ways and break that curse. How wonderful!

    I liked this. My favorite for accessibility on the same subject is Dr Bruce Lipton's book, The Biology of Belief. I believe this whole field will explode our possibilities and the way we think about our environment, physical, emotional, mental. Epigenetics goes a long way towards explaining how Energy Psychology and EFT work so well, documented in the 60+ peer-reviewed published studies. Challenging our convictions is what science is supposed to be all about, and I'm delighted with Courtney Griffins' presentation that paves the way for a better understanding of who we are and how we're impacted, and what we can do with that information.

    @RickMonsour09 Před 10 lety +3

    I am not a geneticist but Dr Courtney makes a great case that demonstrate the effects of lifestyle and personal choices and the outcome of how well we live. It makes sense that our choices will affect our genetic destiny either + or -. There have been lots of examples of genetically identical twins who have made different life style choices and the affects on how they age. This also has been recorded with gene chip analysis which is state of the art technology in measuring objectively how our genes our affected by lifestyle choices. So I don't think what she is saying is mere speculation.

  • @viyoddha8840

  • @shirleya-z794
    @shirleya-z794 Před 7 lety +19

    The thing is no identical twins have identical environments, and there is no way to know how the smallest of differences could or could not impact on personality. This is the inherent flaw in all twin studies, the assumption that twins raised together can be treated as though they have been raised in an identical environment. Her pie chart would have made more sense if it were presented as a venn diagram with epigenetics the area where nature and nurture overlap rather than being separate from nature and nurture.

    • @umbutlikeya6436
      @umbutlikeya6436 Před 5 lety +2

      shirley A-z well contrary to your belief it's been proven. Environmentally enduced epigenetics are part of the reason why identical twins can grow up to have very different luves. As twins get older there, epigenomes diverge affecting the way age and there susceptibility to disease. You missed the whole theory on how over time the environmental experience play a role here. This can be applied to not just twin. You as person can affect your future generations by lifestyle decisions you make now. For example smoking or any stress you react to now. Can come up in future generations decades from now. Depending on what you did, are you quick to panic? Then most likely your grand children will be also. In order to grasp what she explain you need to understand epigenetic changes.

    Thank you and Courtney Griffin for the wonderful video!
    One question (and I must apologize in advance - I am in no way any expert in the area, just have read this and that):
    it is mentioned in the video at 7:20, that there are "not so many" epigenetic marks on the genome in the beginning, and that they begin to appear later in development, as the cells start to divide and receive signals from outside.
    However, what I have read elsewhere, says the oppozite: the zygote - as the ultimate "stem cell" - has most of its genome silenced and genes non-transcribed. And it is early in the blastocyst stage that some of these epigenetic marks (particularly methylgroups) are removed from DNA and acetylgroups added to histones, thus beginning to "lead" the cell towards a certain genetic/developmental trail.
    I have read, that in mice silent genomen becomes not-fully-silent around mid-1-cell stage, although more transcription begins at 2-cell stage. Not sure if it is different in humans.
    Will appreciate the explanation.

  • @StancyInTheCity
    @StancyInTheCity Před rokem +1

    OK, the very first line of epigenetic defence is lifestyle factors. Lifestyle factors are pretty much free and cannot be patented. Because they can’t be patented, researchers aren’t talking about it. There’s no money in it.
    1) a vegan diet, the branch chain amino acids in animal products stimulate MTor add also contain growth hormones. We don’t want growth in cancer.
    2) practice intermittent fasting, having even a 12 hour daily window of not eating decreases your risk of cancer recurrence, it’s been studied.
    3) if you can do a prolonged fast, 7+ days. Have it supervised by your physician. Look at the work of Dr. Valter Longo.
    4)everything should be organic, especially in the United States. Conventional food is loaded with pesticides, they are carcinogenic, and it’s an easy switch.
    5) exercise, it has many biological effects on the human body that contribute to making the body inhospitable to cancer. It lowers, inflammation, combats, obesity, helps regulate hormones.
    6) get your weight into the low range of a healthy BMI. Obesity contributes to cancer. Obesity is very inflammatory.
    7) meditation, stress, hormones can contribute to cancer. Meditation helps control that.
    8) get rid of all unhealthy relationships
    9) make sure you have an actual purpose for living. Get a five year plan a 10 year plan, etc. have a future to look forward to.
    10) join a community, a positive community. People who are going through what you’re going through where you can openly talk about what is really on your mind without retribution. Not a community of people who are anticipating a horrible death. A community of people who are hopeful and excited for the future. They are all over the place, on Facebook, meet ups, etc.

    Great presentation, I was on board until around 15:01 - Teacher's we should be following should be teaching us how to properly prepare the foods we eat and that the life style choices we make (the types of thoughts we think) will determine our physical experience. I have no problem with her description of how gene's express themselves, It just seems intuitive to me, that our science - as good as it is, is still learning to crawl - and this is Huge.

      @sameeahmuhammad8439 Před 2 lety +1

      Thank you. I agree. Also her point at 1:39 about criminal tendencies being more genetically based is a long standing debate that hasn’t been settled yet. NYT published an article a year before her talk saying as much. Many scientists and statisticians say that the sample size of even the largest study about the heritability of criminal tendencies is still too small to fully see the role of genes in this issue. Also the term crime is so vague.. does she mean tax evasion too or just street crime? From what I’ve read it’s more about anti social behavior being linked to certain hormones. That part of her talk seemed off to me

    That was a great talk. I hope your twins (now 21) are well and all your whole family.
    Food for thought.
    Symptoms are the manifestation of faulty cellular processes and are often indicators of more sinister pathology. For example, constipation -- > colon cancer, migraine -- > stroke, irregular cycles -- > ovarian cancer.
    Faulty cellular processes, which this lovely presenter has said, are a function of the epigenome's 'on' or 'off' activity.
    What is important here is this: If a person, and not a drug, can control ( 'on' or 'off' on command) his or her symptoms, they have a window into the microcellular system without the expense associated with precision medicine.
    Do such systems exist? Yes. And more are on the way.
    If so, it disproves that much of the epigenetic instructions occur during embryonic development.
    How do we prove such a system exists?
    By demonstrating voluntary control individuals have to turn symptoms on and off .
    Whilst this was never an assumption in the video, using medications for microcellular control is one form of epigenetic medicine.

    @shannonwilliams2769 Před rokem

    This talk does a great job of discussing the complexities of the relationship between our genes and the environment, particularly through epigenetics. While this discussion is important in and of itself, it also raises important ethical concerns about genetic enhancement and technological affordability, which has the potential to exacerbate already existing inequalities, disparities, and discrimination. One of the major concerns around genetic enhancement technologies is accessibility. If only the wealthy have access to these technologies, it will create a divide between those who have access to enhanced genetic traits and those who do not, leading to social and economic inequality. There is also a risk that these technologies could be used to perpetuate harmful biases, such as racism, sexism, and ableism.

    I have always thought that my ideas were unrealistic when I wrote to different Professors telling them that Cancer and other debilitating diseases can be reversed. All we needed was to find the control switch. Now I feel I am in good company. In the Geneticist's term: "reminding the cells/tissues of what they should be doing".

    I've seen several reviews using the agouti mouse and other models of cross generational epigenetics published in the last few years. Hopefully you're at a place where you can access journal articles. C. elegans has demonstrated 15 generation inheritance of changes caused by exposing eggs to certain compounds. If I recall, vasopresin. Many exposures have been shown after the 3rd generation (before that the germ cells in the developing foetus could have been exposed) so it is a thing.

    I played an Atistic child to better health. What ever it was... exposure to nature, contextual emotions... increased happiness & interest in life ... from play. Or epigenetics... it worked. where people said it could not be.
    nurture here did play a role, bringing the child to nature... and then...
    play saved the child.

    This is very exciting. Instead of destroying Cancer , good cells can be reinstalled or reprogrammed.
    This makes so much more sense to repair rather than destroy!

    Human life is a dangerous undertaking. We need so many protections against harmful elements common in this world.

    The agouti mouse has a promoter that expresses at a rate depending on how methylated the DNA at that promoter is. They hooked that promoter up to a pigment gene so the coat color tells researchers how methylated the DNA of the mouse is. They used this to test if exposing pregnant mothers to various stimuli effect the offspring. They've found several chemicals that have clear cross gen effects. Kinda like lamarkian evolution? If you can find sources on it, it's well worth checking out.

    I am struck by the contradiction between "Your chromatin didn't have many epigenetic marks on it" at 7:10 and "They can also impact the health of your future children" at 17:50. Fascinating topic but I detect a little bit of "good" vs "bad" bias. The biggest question is which are and which are not inherited. It's gonna take a lot of careful research to prove "inheritability of acquired characteristics", discredited in an earlier age as Lamarcrkism.
    Phenotypes don't make value judgements. They are simply either more or less adaptive given certain environmental conditions. And genetic flexibility is a hallmark of genetic diversity.

    A subject that fascinates! as one of four adopted children all very different in many ways..however the “attachment theory” influences the potential for biases that draws attention to the overriding concept that attachment has to be integrated with nurture and then ifof course nature which is imbedded in our genes..these integrated issues affect who we are..

    Would like to see experiments on the effects of Ayahuasca to determine if there are any co-relations between its deprogramming affects from environmental conditioning and epigenetics. It is great to see scientist embracing this research in an attempt to create a pill however nature may already have provided us with the solution through the direct use of plant medicine such as Ayahuasca.

      most medicine is derived from plant chemistry so its entirely possible

      Check out "Fellowship of the River",by Dr. Joe Tafur !! He also posted a video on You Tube about his work. Epigenetic effects are absolutely related to emotional and physical damage. The plant medicine reveals this is where emotional pain is stored, or translated in the body - within epigenetic changes to DNA.
