Inhibition of CDK9 leads to a decrease in RNApol II activity and repetitive element expression. HEK293T cells were treated with DMSO control and the indicated amounts of LDC000067, a CDK9 inhibitor, for a total of 3 h. (A) Immunoblots showing the levels of phosphorylated RNApol II largest subunit (pRPB1), total RPB1 and GAPDH, in response to different doses of CDK9 inhibitor. (B) Quantification of immunoblots from 2 independent experiments in which each condition was performed in duplicates, and in which pRPB1 and total RPB1 protein levels were normalized to GAPDH or as pRPB1/Total RPB1 ratio. (C, D) qRT-PCR analyses show a significant response to CDK9 inhibition of repetitive elements belonging to the LTR (C) and SINE (D) classes. Statistical analyses were performed to compare all groups using a One-way ANOVA followed by Bonforreoni’s multiple comparison test, *P < 0.05, **P < 0.01, #P < 0.0001.

(B) Effects of siRNA-mediated depletion of CDK7, CDK9, or CDK7 and CDK9 on UKF-NB-3 and UKF-NB-3rSNS-032300nM cell viability as determined by MTT assay 72 h post-transfection. Non-targeting 'scrambled' siRNA (scr siRNA) served as control.

Inhibition of JQ1 enhancement effect on Ad2 infection by CDK9 inhibitor. A549 cells were infected with Ad2 in the absence or presence of 300 nM JQ1. For inhibition, LDC00067 was added simultaneously. Viral protein synthesis or virion production was detected at 24 and 36 h PI, respectively. The experiments were performed 2 times independently. Data represent mean ± SD of triplicate samples. *p < 0.05, **p < 0.01.

Western blotting after 24h of LDC000067 treatment, showing the expression of CDK9, RNA Pol II,phosphorylation of RNA Pol II (Ser2 and Ser5), anti-apoptotic proteins Mcl-1 and Survivin, and apoptotic-related protein Bax in (D)SYO-1 and (E) Fuji synovial sarcoma cells. The data are mean SD of the experiment carried out in triplicate.

Bio Calculators
Molarity Calculator
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).
Dilution Calculator
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.
