The relative expression of Oct4, Nanog, Klf4 and Sox2 at the blastocyst stage in ICSI-, ROSI- and ROSI + incubation of zygotes with 250 nM Scriptaid for 10 h (ROSI-S)-derived embryos. Five blastocysts in each pool were examined to obtain the data set in each column. Q-PCR analysis was performed in triplicate. Different letters indicate significant differences between values (P < 0.05).

Inhibitory effects of different concentrations of scriptaid and bortezomib (Borte) on OVP-10 (A) and MDAH 2774 (B) ovarian carcinoma cells. Cancer cells were incubated for 72 h with different concentrations of scriptaid and bortezomib and the cytotoxic effect of the agents was measured using an MTT assay. The data shown are the mean viability ± SD of triplicates.

|Description||Scriptaid (GCK 1026) is an inhibitor of HDAC. It shows a greater effect on acetylated H4 than H3.|
Scriptaid (6 μM) results in a >100-fold increase in histone acetylation in PANC-1 cell. Scriptaid (8 μM) is not lethal to PANC-1 cell and has limited effects (80% survival) on MDAMB-468. Scriptaid increases the transcription of pCMVb, p6SBE-luc and p6MBE-luc independent of a positive inducer of transcription. Scriptaid is capable of inducing high expression of p6MBE-luc, pCMVb, and pUB6/V5-LacZ, driven by viral (SV40 and CMV) or human (ubiquitin c, UB6) promoters, which do not depend on the specificity of the enhancer (SBE versus MBE), the type of promoter (viral versus cellular), the product of the reporter gene (luciferase versus b-gal), nor on the integration status of the reporter construct.  Scriptaid induces high rates of somatic cell nuclear transfer (SCNT) oocytes development to the blastocyst stage and allowed full-term development (3.4, 4.2, 7.6, 6.8, and 4.1%) with all concentrations (50, 100, 250, 500, and 2000 nM respectively). Scriptaid improves the full-term development of cloned B6D2F1embryos in a dose-dependent manner with the maximum effect at 250 nM. Scriptaid enables the clone of all the important inbred mouse strains, such as C57BL/6, C3H/He, DBA/2, and 129/Sv. Scriptaid treatment enhances newly synthesized mRNA levels in cloned embryos. 250 nM Scriptaid treated for up to 48 h, does not inhibit the development of ICSI-fertilized embryos.  Scriptaid inhibits T. gondii tachyzoite proliferation with IC50 of 39 nM. Scriptaid (0.225 μM) completely protects the HS68 monolayers from T. gondii tachyzoite.  Scriptaid inhibits growth of ER negative cell lines, MDA-MB-231, MDA-MB-435 and Hs578t with IC50 of 0.5-1.0 μg/mL after 48 h treatment. 1 μg/ml Scriptaid treated for 48 h induces an accumulation of both acetylated H3 and acetylated H4 histone tail proteins, and a maximal of 20,000-fold increase of ER mRNA transcript.  Scriptaid inhibits the proliferation and viability of the Ishikawa endometrial cancer cell line, and the SK-OV-3 ovarian cancer cell line with IC50 of 9 μM and 55 μM, respectively, while the normal human endometrial epithelial cells shows little sensitivity. Endometrial cancer cells and ovarian cancer cells cultured for 2 days in the presence of Scriptaid shows an accumulation in the G0/G1 phase (5 μM of Scriptaid) and G2/M phase (10 μM of Scriptaid) of the cell cycle, with a concomitant decrease in the proportion of those in the S phase. 10 μM of Scriptaid induces a 56.1% of apoptotic Ishikawa cells with loss of mitochondrial membrane potential, and decreased levels of cyclin A and bcl-2 levels by 50% and 20%, respectively. 
|In vivo||Scriptaid elicits a dose-dependent decrease in lesion size (a maximal decrease of 45%) at 1.5 to 5.5 mg/kg and a concomitant attenuation in motor and cognitive deficits when delivered 30 minutes postinjury in a model of mode rate TBI. Comparable protection is achieved even when treatment is delayed to 12 h postinjury. The protection of motor and cognitive functions is long lasting, as similar improvements are detected 35 days postinjury. Scriptaid induces an increase in surviving neurons (42%), as well as the number/length of their processes within the CA3 region of the hippocampus and the pericontusional cortex. Scriptaid treatment prevents the decrease in phospho-AKT (p-AKT) and phosphorylated phosphatase and tensin homolog deleted on chromosome 10 ( p-PTEN) induced by TBI in cortical and CA3 hippocampal neurons.  Scriptaid treatment (3.5 mg/kg) clearly inhibits tumor growth in a human breast cancer xenograft MDA-MB-231 model, reducing tumor volume by 75%. |
Immunoblotting assay of histone acetylation:PANC-1 cells are treated with 2 μg/mL of Scriptaid for 18 h in culture medium. Treated and untreated cells are harvested with trypsin-EDTA, washed with PBS, and resuspended in a protein sample buffer. Protein concentration is determined by BCA protein assay reagents. Fifty μg of proteins from each sample is loaded on a 12% denaturing polyacrylamide gel. Proteins are subsequently transferred to a nylon membrane using MilliblotGraphite Electroblotter I. The nylon membrane is incubated with rabbit antihuman acetyl-lysine antibody, followed by goat antirabbit antibody coupled to horseradish peroxidase, developed with SuperSignal substrates, and detected by film.

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
