Description

A genomic region can become transcriptionally quiet or active over the course of cell mitosis as a result of heritable changes in the chromatin structure of the area. A growing body of research has shown that variations in the patterns of DNA methylation and histone modifications two well-known epigenetic mechanisms have phenotypic effects. Thus, the epigenome is a promising therapeutic target. Traditional Chinese Medicine (TCM) is a system of treatments that has existed for more than 2100 years and is still a well-liked complementary therapy in various Far East Asian populations. We looked for chemicals that interact with proteins linked to epigenetics in 3294 TCM medicines (TCMMs), which contain 48 491 compounds. We discovered that 29.8% of the TCMMs regulate the epigenome and miRNA primarily through interactions with Polycomb.

200 TCM formulae (TCMFs) that have received government approval were examined, and it was discovered that 99% of them interact with the epigenome and miRNA. The Monarch medicines are shown to interact most strongly with the epigenome and miRNA. The TCMFs, many of which are tonic, heavily exploit histone alterations. The Assistant medicines also resemble the Monarch the least epigenetically. We assessed the role of epigenetics in TCM prescription and discovered that information on the epigenome and miRNA interactions alone 20% of the clinical applications of the TCMFs. Our findings offer I more evidence that the epigenomes are pharmacological targets and (ii) a new set of tools for creating TCM prescriptions.

40% of US individuals, according to a recent survey, used alternative and Complementary Medicine (CAM) therapy at least once in the previous year. Even more frequently, 63% of persons over 65 reported using CAM. A system of beliefs and treatments known as Traditional Chinese Medicine (TCM) has been practised in China for more than 2100 years. Since then, it has seen significant development and advancement in China, both with the support of the government and independent practitioners. TCM has survived the demise of contemporary Western medicine and is still widely used as a Complementary And Alternative Medicine (CAM) by inhabitants in Far East Asia. Standardized TCM formulae (TCMFs) have been certified by the health regulatory agencies in particular in China, Japan, Korea, and Taiwan and are therefore covered by the public health insurance. TCM uses a combination of acupuncture, chiropractic care, and natural items as part of its treatment plan. In this essay, we only cover how natural items with well-known chemical formulas are used in TCM.

According to TCM, a person's illness is caused by an imbalance of the opposing components in one or more regions of the body. In general, the opposing forces are referred to as yin and yang. A TCM practitioner classifies a patient's symptoms into various yin or yang deficient groups. The yin-yang balance is then restored by using TCM medicinals (TCMMs), which are divided into yin- or yang-enhancing categories. The intangible yin-yang and other differentiations of a patient, such as emptiness-fullness and coolness-warmness, and the associated TCM treatments reflect, in part, the shortcomings of the diagnostic and clinical methods of the ancient East in comparison with the advancements in biochemistry and molecular biology of the modern West.

The sustainability and revival of TCM demand that it be modernised, with one of the primary goals being the standardisation of TCM terms, materials, and formulations. Our strategy for achieving the goal takes into account identifying the epigenetic mechanisms in TCMMs and TCMFs. The majority of TCM prescriptions a patient receives are the latter, which are made up of combinations of the former.

In terms of epigenetics, changes in gene expression that are persistent during mitosis but do not result in changes to the underlying DNA sequence are referred to. Methylation of CG dinucleotides, post-translational changes of histone proteins, and RNA interference are examples of well-known epigenetic mechanisms in mammalian cells. For instance, histone deacetylation, microRNA (miRNA) production, and DNA methylation are linked to gene silence. A cell's epigenetic mark profile (also known as its epigenome) and miRNA expression are susceptible to environmental changes, and aberrations in the mark profile might increase a person's susceptibility to morbid phenotypes including Alzheimer's disease, autoimmune illness, and heart disease. The human proteins that are the focus of our study are thought to be expressed in the majority of cell types and are known to play a role in epigenetic control. In addition to DNA Methyltransferase (DNMT), Histone Deacetylase (HDAC), Histone Acetyltransferase (HAT), Histone Methyltransferase (HMT), Methyl Cpg-Binding Protein (MBD), Polycomb Group Protein (PcG), Drosha and Dicer (DICER) and their families, there are also several more proteins in this group. The chromatin is modified covalently by the first four. Heterochromatic loci exhibit (co)localization of MBDs and PcGs. To create mature miRNA, DICER processes miRNA precursors. The interactions of a TCMM with human proteins were then investigated for indications of epigenome and miRNA modification.

The taxonomical kingdom, TCM nature, TCM flavour, and TCM meridian features of a TCMM are of interest because they serve as a guide for its functions. We determined the TCMMs' overrepresented properties that interact with the epigenome and miRNA. A TCMM may play one of four roles depending on its function in the formula: I Monarch focusing on the primary syndrome, (ii) Minister enhancing the effect of the Monarch or addressing the patient's secondary syndromes, (iii) Assistant enhancing the curative effect of the Monarch and Minister or attenuating the drastic and toxic effect of the Monarch and Minister, and (iv) Guide coordinating or directing the prescription to the affected area of the body.

A characteristic of malignant cells is thought to be both gene-specific hyper methylation and genome-wide hypomethylation. Many TCM medications are thought to affect a person's constitution permanently. Additionally, it is believed that TCM prescriptions lack target specificity in contrast to the specialised receptor/pathway targeting of contemporary Western medications. TCM's first characteristic is similar to how (acquired) epigenetic patterns are maintained via somatic cell divisions, while its second characteristic is similar to I the epigenetic (dys)homeostasis that affects the entire epigenome and (ii) a single miRNA that targets several mRNA sequences. Our concept of an epigenetic role in the pharmacology of TCM prescriptions was driven by the correspondences.

By thoroughly examining a huge number of TCMMs and TCMFs, which is now possible in the age of data explosion and open access, the notion was addressed. In particular, we used a chemical-protein association database, which comprises 10 288 993 pairs of chemical-protein interactions, to learn about direct connections between substances and enzymes involved in epigenetics. From two TCMM databases, which combined comprise 48 491 chemicals in 3294 TCMMs, we obtained the data regarding the chemicals in TCMMs. We collected the chemical make-up of 200 standardised TCMFs, the prescriptions for which are covered by Taiwan's public health insurance, from a government database.
