Type: enzyme
G9a is a histone methyltransferase enzyme that plays a crucial role in various cellular processes, including gene expression, DNA repair, and cell cycle regulation.
G9a has been found to be overexpressed in various types of cancer, including breast, lung, colon, and prostate cancer. This overexpression is often associated with poor prognosis and reduced survival rates.

672- EGCG,    Molecular Targets of Epigallocatechin—Gallate (EGCG): A Special Focus on Signal Transduction and Cancer
- Review, NA, NA
DNMT1↓,
HDAC↓, HDAC1, HDAC2
G9a↓,
PRC2↓,
DNMT3A↓,
67LR↓, anti-proliferative action of EGCG is mediated by the binding to 67LR, whose expression is increased in tumour cells.
Apoptosis↑,

3359- QC,    Quercetin modifies 5′CpG promoter methylation and reactivates various tumor suppressor genes by modulating epigenetic marks in human cervical cancer cells
- in-vitro, Cerv, HeLa
DNMTs↓, When nuclear extracts were incubated with increasing doses of quercetin (25 and 50uM) they were found to inhibit the function of the DNMTs by 32% and 49% respectively, in comparison to untreated control
HDAC↓, quercetin (25 and 50 uM), they were found to inhibit the function of the HDACs by 47% and 62% in comparison to untreated control.
HMTs↓, quercetin (25 and 50 uM), were found to inhibit the function of the HMT H3K9 by 63% and 71%
DNMT3A↓, preferred binding of quercetin on DNMT3A and DNMT3B is within the substrate binding cavity and could competitively inhibit the protein
EZH2↓, Quercetin interacts with EZH2 and functions as an inhibitor
HDAC1↓, Quercetin was able to reduce the activity of class II HDACs significantly, with concomitant downregulation of HDAC1, HDAC2, HDAC6, HDAC7, and HDAC11 expression
HDAC2↓,
HDAC6↓,
HDAC11↓,
G9a↓, quercetin and this correlates well with the observed downregulation of G9A expression
TIMP3↑, Fig8: quercetin resulted in reduced promoter methylation of several TSGs (APC, CDH1, CDH13, DAPK1, FHIT, GSTP1, MGMT, MLH1, PTEN, RARB, RASSF1, SOC51, TIMP3, and VHL
PTEN↑,
SOCS1↑,

3424- TQ,    Thymoquinone Is a Multitarget Single Epidrug That Inhibits the UHRF1 Protein Complex
- Review, Var, NA
DNMT1↓, In this review, we highlight TQ as a potential multitarget single epidrug that functions by targeting the UHRF1/DNMT1/HDAC1/G9a complex
HDAC1↓,
TumCCA↑, inhibition of cell division, promotion of cell cycle arrest, activation of ROS production, induction of apoptosis and inhibition of tumor angiogenesis and metastasis
ROS↑,
Apoptosis↑,
angioG↓,
TumMeta↓,
selectivity↑, When compared to its effects on cancer cells, TQ has no or only mild cytotoxic effects on matched normal cells, such as normal human fibroblast cells [
BioAv↓, poor pharmacokinetics and chemical stability of TQ
BioAv↓, TQ is heat and light-sensitive, and it has poor solubility in aqueous media, which affects its biodistribution
HDAC1↓, T-ALL TQ decreased in the expression of HDAC1, 4 and 9
HDAC4↓,
UHRF1↓, TQ induces auto-ubiquitination of UHRF1 and subsequent degradation in cancer cells [23] by targeting its RING domain, which is the only domain of the UHRF1 structure that exhibits enzymatic activity
selectivity↑, via a specific inhibition of UHRF1 expression levels in cancer cells without affecting its expression in normal human cells.
G9a↓, TQ could quite possibly inhibit G9a and/or delocalize it from chromatin through its effects on UHRF1.

3426- TQ,    Thymoquinone-Induced Reactivation of Tumor Suppressor Genes in Cancer Cells Involves Epigenetic Mechanisms
- in-vitro, BC, MDA-MB-468 - in-vitro, AML, JK
UHRF1↓, (UHRF1), DNMT1,3A,3B, G9A, HDAC1,4,9, KDM1B, and KMT2A,B,C,D,E, were downregulated in TQ-treated Jurkat cells
DNMT1↓,
DNMT3A↓,
DNMTs↓,
HDAC1↓,
HDAC4↓,
HDAC↓,
DLC1↑, several TSGs, such as DLC1, PPARG, ST7, FOXO6, TET2, CYP1B1, SALL4, and DDIT3, known to be epigenetically silenced in various tumors, including acute leukemia, were upregulated,
PPARγ↑,
FOXO↑,
TET2↑,
CYP1B1↑,
G9a↓, expression of UHRF1, DNMT1, G9a, and HDAC1 genes in both cancer cell (Jurkat cells and MDA-MB-468 cells) lines depends on the TQ dose
