生物活性

製品説明 トリコスタチンA (TSA (Trichostatin A) ) は HDAC 阻害剤であり、IC50 は cell-free assay において < 1.8 nM です。
Targets
HDAC [1]
(Cell-free assay)
~1.8 nM
In Vitro
In vitro Trichostatin A inhibits the proliferation of eight breast carcinoma cell lines including MCF-7, T-47D, ZR-75-1, BT-474, MDA-MB-231, MDA-MB-453, CAL 51, and SK-BR-3 with mean IC50 of 124.4 nM (range, 26.4-308.1 nM), with more potency against cell lines that express ERα than the ERα-negative cell lines. Trichostatin A inhibits HDAC activity similarly in all the breast cancer cell lines with mean IC50 of 2.4 nM (range, 0.6-2.6 nM), and results in pronounced histone H4 hyperacetylation. [1] Unlike Trapoxin (TPX) and Chlamydocin which potently inhibit HDAC1 or HDAC4 but not HDAC6, Trichostatin A inhibits these HDACs to a similar extent with IC50 of 6 nM, 38 nM, and 8.6 nM, respectively. [2] Trichostatin A (100 ng/mL) treatment induces the expression of transforming growth factor β type II receptor (TβRII) in MIA PaCa-2 cells through the recruitment of p300 and PCAF into a Sp1-NF-Y HDAC complex that binds the DNA element of TβRII promoter, which is associated with a concomitant acetylation of Sp1 and an overall decrease in the amount of HDAC associated with the complex. [4]
Kinase Assay In vitro HDAC activity
Total cellular extracts are prepared from each breast cancer cell line (MCF-7, T-47D, ZR-75-1, BT-474, MDA-MB-231, MDA-MB-453, CAL 51, or SK-BR-3). A 20 μL crude cell extract (~2.5 ×105 cells), in the presence of varying concentrations of Trichostatin A in 0.1% (v/v) ethanol or 0.1% (v/v) ethanol as vehicle control, are incubated for 60 minutes at 25 °C with 1 μL (~1.5 × 106 cpm) of [3H]acetyl-labeled histone H4 peptide substrate (NH2-terminal residues 2-20) that has been acetylated with [3H]acetic acid, sodium salt (3.7 GBq/mmol) by an in vitro incorporation method. Each 200 μL reaction is quenched with 50 μL of 1 M HCl/0.16 M acetic acid and extracted with 600 μL of ethyl acetate, and released [3H]acetate is quantified by scintillation counting. IC50 values are determined graphically using nonlinear regression to fit inhibition data to the appropriate dose-response curve.
細胞実験 細胞株 MCF-7, T-47D, ZR-75-1, BT-474, MDA-MB-231, MDA-MB-453, CAL 51, and SK-BR-3

実験の流れ

Cells are exposed to various concentrations of Trichostatin A for 96 hours. After treatment, cell proliferation is estimated using the sulforhodamine B colorimetric assay. Cell viability is determined by trypan blue exclusion.

In Vivo
In Vivo Administration of Trichostatin A at 0.5 mg/kg for 4 weeks displays potent antitumor activity in the N-methyl-N-nitrosourea carcinogen-induced rat mammary carcinoma model, without any measurable toxicity at doses up to 5 mg/kg. [1] Single intraperitoneal doses of 10 mg/kg Trichostatin A in nontransgenic and spinal muscular atrophy (SMA) model mice results in increased levels of acetylated H3 and H4 histones and modest increases in survival motor neuron (SMN) gene expression. Administration of Trichostatin A at 10 mg/kg/day improves survival, attenuates weight loss, and enhances motor behavior in the SMA model mice. [5]
