HDAC1 Cancer Research Results

HDAC1, Histone Deacetylase 1: Click to Expand ⟱

Source:

Type:

HDAC1 is an enzyme that removes acetyl groups from histone tails, resulting in chromatin condensation and transcriptional repression.
– By modulating the acetylation status of histones, HDAC1 plays a key role in regulating gene expression involved in cell cycle progression, differentiation, apoptosis, and DNA repair.
– Aberrant expression or activity of HDAC1 has been linked to several cancers.
– Overexpression of HDAC1 can lead to the repression of tumor suppressor genes, thereby promoting oncogenic programs and contributing to tumor progression.
– HDAC1 is often associated with a more aggressive tumor phenotype and, in some contexts, a poorer clinical prognosis.
Therapeutic Targeting:
– HDAC inhibitors (HDACis) have emerged as anticancer agents; they work by inhibiting HDAC activity to restore acetylation levels on histones and nonhistone proteins.

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
