    Excellent explanation: concise, jargon-limited, and straight to the point. We need more 3-5 minute videos explaining complicated processes to the public at large.
    Thanks again!

    Highly impressed with this vedioclip and for the first time through your deliberation a professor has understood this complex process. Thank you very much indeed. Would love to learn from you more and more Sir! Regards

    So presumably hyper-methylation can deactivate a lot of DNA repair genes too.

    please correct me any part of the statements if they are wrong.
    I understood that:
    1) promoter DNA methylation is a NORMAL action in response to the environment/epigenetics and ultimately results in gene silencing.
    2) CpG site(s) methylation (another NORMAL nature of genome) ultimately creates different cell types and furthers their division (via unique methylation patterns per cell type, across the genome of cell types).
    3) It is UNCOMMON for PROMOTER CpG islands to be methylated, because they (promoter regions) have important regulatory elements that control gene transcription (and shouldn't be 'messed' with).... and offset balance of promoter dna methylation and CpG island methylation.....
    4) So, in cancer cells we not only have the UNCOMMONality of the methylation of DNA PROMOTER CpG islands, but they are HYPERMETHYLATED. This means
    the normal inactivation for silencing of the gene for suppressing tumors is otherwise, due to hypermethylation, now allowed to be activated (so NO silencing of gene for suppressing tumors) and thus, allowed to differentiate/divide/aka behave like a tumor and go crazy!.......
    Let me know.
    Thanks!

      Do you have updated knowledge about this? For "promoter cpg islands", do you know if they can be methylated on purpose via, let's say, supplementation with methylated b vitamins?

    Naive question: Could manipulation of the methylation on DNA cause a generation of a stem cell. Is a stem cell just one that has yet to undergo any methylation (expressing all genes)?

    There is an "H" miising on each cytosine at the 1-N position. Or you could just write "Rest".

    • @tievoli83
      @tievoli83 4 ปีที่แล้ว +2

      DNMT1o is synthesized and stored in the cytoplasm of the oocyte and translocated to the cell nucleus during early embryonic development, while the somatic DNMT1 is always found in the nucleus of somatic tissue.

    I have experienced very severe neurological disorders with the use of PPIs.
    I have the characteristics under methylation _ I learned this with my own research after the disorder_
    I can't get rid of paresthesias, especially pins and needles.
    What can you suggest me about this?

    Question..... can anyone explain or give clarity on the following ... does any change to typical Purine & Pyrimidine, folate, B6 or B12 pathways during pre or early post natal periods result in heritable genetics that could be passed from that baby should they procreate in later life?

    Very good, most of it I got it, but I didn't understand the flip part of CpG. If DNMT3a and DNMT3b already methylated, is that cause the flip and later when it obtains methyl from SAM it comes back?
