Abstract

For years many have believed that genetic heritage defined one’s destiny, if an individual would grow to be healthy, or if he or she would suffer from chronic illness or cancer. Recent scientific evidence and the field of epigenetics has proven this to be untrue. Certainly, the DNA sequence and the genetic code are fixed; but the field of epigenetics has shown how methylation and other chemical modifications of the genome directly influence the production of proteins that can alter the phenotype of an organism. This article will lay out the supporting research, the details on how the internal and external environments influence genetic function, and will allow the reader to develop an action plan necessary to influence the genetic code, with the goal of then moving the individual toward optimal health. These research details will enable health care professionals in every field of medicine to work with patients on positively influencing the genetic output in order to improve the quality of life and longevity.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • At the TNF-α locus, epigenetic changes lead to a change in chromatin structure from heterochromatin to euchromatin, and methylation marks are replenished mediated by the MLL enzyme.

    “At its locus, it leads to a change in chromatin structure (from heterochromatin to euchromatin), and methylation marks have also been replenished at this level mediated by the mixed lineage leukemia (MLL) enzyme.”

    From Revisiting Epigenetics Fundamentals and Its Biomedical Implications (2024) · cites this paper as [87]

    The Objectives section describes epigenetics as involving conformational changes in chromatin, and the paper’s opening section discusses methylation as a genomic modification; page numbers are unavailable in our copy. Neither passage establishes a heterochromatin-to-euchromatin transition at the TNF-α locus or says that MLL replenishes methylation marks (searched: TNF, heterochromatin, euchromatin, MLL). (LLM, conf=0.77)

    Experimental — accuracy not yet measured
  • Overexpression of TNF-α has been observed in rheumatoid arthritis, Crohn's disease, ulcerative colitis, and asthma.

    “The overexpression of TNF-α has been observed in a wide variety of inflammatory diseases, such as rheumatoid arthritis, Crohn’s disease, ulcerative colitis, and asthma [86,87].”

    From Revisiting Epigenetics Fundamentals and Its Biomedical Implications (2024) · cites this paper as [87]

    The 'What About the Father?' section mentions asthma risk in relation to delivery and the infant microbiome, but does not discuss TNF-α overexpression. Searches for TNF-α, tumor necrosis factor, and the named inflammatory diseases found no passage in our copy addressing the claimed association. Page numbers were not available. (LLM, conf=0.74)

    Experimental — accuracy not yet measured
  • During tumorigenic progression, loss of expression of tumor suppressors RB1, BRCA1, APC, MLH1, and VHL has been observed due to hypermethylation at the promoter level.

    “To cite an example, during tumorigenic progression, the loss of the expression of tumor suppressors—such as RB1; breast cancer type 1, BRCA1; anaphase promoting complex, APC; DNA mismatch repair protein MLH1; and Von Hippel–Lindau tumor suppressor VHL—has been observed due to hypermethylation at the promoter level.”

    From Revisiting Epigenetics Fundamentals and Its Biomedical Implications (2024) · cites this paper as [87]

    The DOHaD section says that methylation can influence protein production, and the section on inheritance discusses gene expression in men with early prostate cancer. Neither addresses promoter hypermethylation during tumorigenic progression or loss of expression of RB1, BRCA1, APC, MLH1, or VHL. Searches for those genes and the claimed mechanism found no supporting passage in our copy. (LLM, conf=0.76)

    Experimental — accuracy not yet measured
  • miRNAs target the BACE1 protein that regulates the production of amyloid beta platelets, Aβ, which when accumulated contribute to neuroinflammation and progression of Alzheimer's disease.

    “Likewise, it has been reported that there are miRNAs that target the BACE1 protein that regulates the production of amyloid beta platelets, Aβ, which, when accumulated, contribute to the neuroinflammation and progression of this disease [86,87,88].”

    From Revisiting Epigenetics Fundamentals and Its Biomedical Implications (2024) · cites this paper as [87]

    The Objectives passages discuss early-life epigenetic changes and metabolic disease, not Alzheimer’s disease. Searches of our copy for BACE1, miRNAs, amyloid beta, and neuroinflammation returned no passage addressing the attributed mechanism. (LLM, conf=0.74)

    Experimental — accuracy not yet measured
  • In Alzheimer's disease, changes have been identified in the methylation status of CLU, ABCA7, MS4A6A, and CD2AP, which have been reported to contribute to the development of the disease.

    “On the other hand, in Alzheimer’s disease, for example, changes have been identified in the methylation status of proteins such as human clusterin CLU; ATP binding cassette subfamily A member 7 ABCA7; MS4A6A; and CD2AP, which have been reported to contribute to the development of the disease.”

    From Revisiting Epigenetics Fundamentals and Its Biomedical Implications (2024) · cites this paper as [87]

    The DOHaD section discusses methylation and gene expression generally, but does not address Alzheimer’s disease or methylation changes in CLU, ABCA7, MS4A6A, or CD2AP. Searches for those gene names and for Alzheimer’s disease with methylation found no passage supporting the attributed claim. (LLM, conf=0.74)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
