Epigenetics and the influence of our genes | Courtney Griffins | TEDxOU

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

[@brainhax6758]

can certain athletic properties or abilities be manipulated by epigenetics i.e. continuous practice of certain ability, these things kinda demotivate me

[@LineKernel]

actually since 2012 CRISPR - CAT9 we can

[@mariarichter6240]

Thank you, I now understand epigenetics better than reading my book for my class . Very well explained.

[@vinnienauta]

This is AMAZING!! GREAT INFORMATION! what blew my mind was 50 trillion cells in a human body, each cell having a strand of 6 feet of DNA in each cell, and each of DNA are fit into this 400000 times small than a cell in a nucleus cell! WOW!! that is what blew my mind! I'm happy to learn this!

[@marktwain368]

This is the most extraordinary discovery since DNA itself (c.1953). It explains so much that we did not realize about human functioning and dysfunction. This lady is a wonderful teacher.

[@misterrandom4485]

such a great way to present fairly complex concepts, loved the way she did the pauses between sentences, words, and also how the powerpoint was short and spot on on the stuff that is greatly helped by images. Not to say about the subject, GREAT talk

[@slimanelamia3225]

Totally agree with you

[@akrcda]

Excellent speaker who made the concepts quite accessible. I’m very interested to learn more about this emerging field while also inspired to go back and learn the fundamentals of DNA, genetics and organic chemistry to better understand the topic.

[@JondiWhitis]

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.

[@guillermodehollander]

Absolutely beautifully presented and explained. I actually think I understood most of what Courtney said. Beautifully composed sentences, very pleasant voice. No extraneous words. I loved it! 💐🌿🌹🌿💐

[@bluejean4444]

A reason for hope. Generational curses don't always have to be passed on to the third and fourth generation.

[@donandvickitwiford9349]

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!

This is one of the most amazing lectures of Epigenetics. Ummm, now I can understand that is now everything is lost. Means if our parents had bad habits, as not eating healthy and another things against our bodies, we can change and be healthy...

[@dr.dmitry.sokolov]

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.

[@fionamacleod30]

What a wonderful ted talk. Thank you Courtney!

[@nsingh7]

Such a brilliant talk! Thanks.

[@SciencebyJuhi]

One of the most knowledgeable video that I haven't see before this

[@RickMonsour09]

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.

[@MatheoGalatis]

I love this topic! We are not doomed by our genetic heritage. They provide the perfect conditions for us to grow and live our greatest potential. Additional to the creation of medicines that can support gene heritage are a number of psychotherapeutic methods that can heal genetic expressions inherited from our ancestors.

Excellent! I believe its all true as i have asthma and i started a raw plant based diet and it is already helping my asthma. My plan is to stick with it and journal my findings. It has also cut down my meds 40 percent so far. I understand asthma is a chronic disease but i also believe there is a lot you can do to manage it and help yourself. Most of all i dont miss the sweets, processed foods or junk food❤

Muito bom!! Grata por compartilhar seu conhecimento

[@alecrisser12]

This is great mental exercise; like many TED Talks

[@Jervns]

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]

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

[@elizabethfreer1948]

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..

[@shannonwilliams2769]

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.

[@WorthlessWinner]

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.

[@shirleya-z794]

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]

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. Watch the video titles What is epigenetic by Carlos Guerrero

[@rashadhaque5636]

Also, I know identical twins where one is right-handed and the other is left-handed

[@jordancox8294]

That's why the tests are done with twins who have been separated since birth.

[@adamjenkins1399]

The interaction of our genes with our immediate environment (whatever the stage of development) shouldn't be that much of a shock, people. It's good that they can measure this process at a microscopic level, though. And an interesting subject , nonetheless!

[@eyemallears2647]

Thank you

[@TomaloTV]

how was it linked the smoking in sweden and Uk to health risk factors in future generations? how were the other variables ruled out? like wreckless life for example due to other aspects

[@WorthlessWinner]

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.

[@kimmi9697]

intelligent woman! amazing and wonderful subject! thank u so much!

Impactante!!

[@danieldahdah7431]

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.
