HDAC Cancer Research Results

HDAC, Histone deacetylases: Click to Expand ⟱
Source:
Type:
Enzymes involved in regulating gene expression by removing acetyl groups from histones, the proteins around which DNA is wrapped.
-Many cancers exhibit altered expression levels of HDACs, which can contribute to the dysregulation of genes involved in cell growth, survival, and differentiation.
-HDACs can repress the expression of tumor suppressor genes, leading to uncontrolled cell proliferation and survival. This repression can be a key factor in the development and progression of cancer.
-HDAC inhibitors (HDACi) have been developed and are being investigated for their ability to reactivate silenced genes, induce cell cycle arrest, and promote apoptosis in cancer cells.
-HDAC1, HDAC2): Often overexpressed in various cancers, including breast, prostate, and colorectal cancers. Their overexpression is associated with poor prognosis.
-HDAC4, HDAC5): These may have both oncogenic and tumor-suppressive roles depending on the context and cancer type.
-While HDACs are not classified as traditional oncogenes, their overexpression and activity can contribute to oncogenic processes.
-HDAC inhibitor works by preventing the removal of acetyl groups from histones, thereby modulating gene expression, influencing cell behavior, and potentially reversing aberrant gene silencing seen in various diseases.
-HDAC inhibitors can help reactivate these genes, thereby inhibiting growth and inducing apoptosis in cancer cells.

2816- CUR,    NEUROPROTECTIVE EFFECTS OF CURCUMIN
- Review, AD, NA - Review, Park, NA
*neuroP↑, Curcumin has an outstanding safety profile and a number of pleiotropic actions with potential for neuroprotective efficacy, including anti-inflammatory, antioxidant, and anti-protein-aggregate activities.
*Inflam↓,
*antiOx↑,
*BioAv↓, despite concerns about poor oral bioavailability, curcumin has at least 10 known neuroprotective action
*AP-1↓, Curcumin inhibition of AP-1 and NF-κB-mediated transcription occurs at relatively low (<100 nM) doses and might be due to inhibition of histone acetylase (HAT) or activation of histone deacetylase (HDAC) activity
*NF-kB↓,
*HATs↓,
*HDAC↑,
Dose↑, At high doses (>3 µM) that are relevant to colon cancer but unlikely achievable with oral delivery in plasma and tissues outside of the gut, curcumin can act as an alkylating agent,10 a phase II enzyme inducer,11 and stimulate antioxidant response el
*ROS↓, We also found that curcmin reduced oxidative damage, inflammation, and cognitive deficits in rats receiving CNS infusions of toxic Aβ
*cognitive↑,
*Aβ↓, dose-dependently blocked Aβ aggregation at submicromolar concentrations

3234- EGCG,  Rad,    EGCG, a tea polyphenol, as a potential mitigator of hematopoietic radiation injury in mice
- in-vivo, Nor, NA
*DNMTs↓, EGCG (epigallocatechin gallate), a tea polyphenol with known DNMT inhibitory property, in C57 Bl/6 mice model.
*radioP↑, EGCG reduced cytogenetic damage to bone marrow cells in radiation exposed mice significantly
*HDAC↑, ELISA assay with bone marrow cell lysates showed EGCG as an inhibitor of HDAC activity

3193- SFN,    Epigenetic Therapeutics Targeting NRF2/KEAP1 Signaling in Cancer Oxidative Stress
- Review, Var, NA
DNMTs↓, SFN, a natural phytochemical, primarily attenuates both DNMTs and HDACs, individually suppressing DNA hypermethylation and histones deacetylation, ultimately upregulating NRF2.
HDAC↑,
NRF2↑,
DNMT1↓, significant attenuation of DNMT1 and DNMT3a contributed to a decrease in the methylated CpG ratio in the NFE2L2 promoter region in an SFN dose- and time-dependent manner, thus increasing NRF2
DNMT3A↓,
NQO1↑, consequently increasing the transcription of its target genes such as NQO1 and catechol-O-methyltransferase (COMT)
COMT↑,
TumCG↓, SFN may prevent or slow the growth of recurrent prostate cancer, essentially without severe adverse events.
*toxicity↓,
