RNA incorporating drugs induce SG assembly. HeLa cells were treated with the RNA incorporating agents 5-azacytidine (50 uM) and 6-thioguanine (10 uM), or the DNA incorporating agents trifluorothymidine (10 uM) and gemcitabine (100 nM) for 72 h. Subsequently, the cellular localization of the SG marker protein TIAR (green) and the P-body marker protein DCP1 (red) was analyzed. Nuclei were stained with Hoechst. Scale bars represent 20 um.

Analysis of CD31-positive staining in EMT-6 tumour treated with anti-CTLA-4 therapies. (A)EMT-6/P tumours were implanted s.c. into female Balb/c mice. Tumour bearing mice were treated with (i.e. a repeat of the experiment shown in Figure 2) saline control, CTLA-4, metronomic CTX (ld CTX), gemcitabine (Gem), or CTLA-4 plus ld CTX, or CTLA-4 with sequential Gemcitabine. The experiment was terminated as the tumours were starting to respond to the different therapies, as assessed by caliper measurements. Tumours were resected, fixed, and then paraffin embedded, and 5μ sections were then stained (brown) for CD31 (black bar=100 μ). (B) Image analysis of × 20 pictures of CD31 immunohistochemistry of tumour tissues from control- and drug-treated groups of mice. The quantification of the images was performed by the image analysis software ImageJ (Image Processing and Analysis in Java; Wayne Rasband, Research Services Branch, National Institute of Mental Health, Bethesda, MD, USA) and the results are shown as the ratio between the CD31-positive area and the total area of the image. A one-way ANOVA analysis followed by Bartlett’s post test was applied to the results to demonstrate significant differences among the treatment groups. The statistical analysis of the data was performed with GraphPad Prism v.5.0. Blue lines, mean±s.d.; *P<0.05 vs control group.

Injection of low-dose GEM suppresses tumor growth in vivo. BALB/c mice were injected s.c. with 5x 10^5 CT26 cells into the right flank. On day 10, mice were injected i.p. with GEM (50 or 100 mg/kg). Arrows indicate the injection of GEM. Tumor size(mm2) was measured twice weekly. Each group consisted of five or six mice, and lines represent tumor growth in each mouse. The mean ± SD of the results on day 30 after tumor inoculation are also shown. Similar results were obtained in two experiments. *P\0.05 indicates statistical significance by ANOVA with Dunnett’s post hoc test. NS, not significant.

Cells were seeded in 96 well paltes, and then treated with the indicated concentration of Gemcitabine for 48 h. Cell survival was measured by a standarad MTT assay.

| In vitro |
Gemcitabine induced NF-κB activity in BxPC-3, PANC-1, and MIA PaCa-2 cells and decreased the level of the NF-κB inhibitor IκBα in BxPC-3 and PANC-1 cells. Treatment of BxPC-3 cells with low dose Gemcitabine for 48 hours results in a dose-dependent increase in NF-κB binding. In contrast, NF-κB DNA binding is decreased in BxPC-3 cells treated with the higher Gemcitabine doses for 48 h; however, 24-h treatment with these higher doses increases NF-κB binding in BxPC-3 cells [2] |

| In vivo | Intratumoral NF-κB activity is significantly elevated (1.3- to 1.8-fold) in the Gemcitabine-treated mice compared to the PBS-treated mice, suggesting that Gemcitabine also induces NF-κB activation. [2] |

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 (g) = Concentration (mol/L) × Volume (L) × 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.

Frequently Asked Questions
-
Question 1:
What’s the difference between S1714 and S1149 and which one is better?
-
Answer:
They have the same biological activities. The free base(S1714) dissolves better in DMSO, and the hydrochloride (S1149) dissolves better in water.
