Plk inhibitor cooperates with chemotherapeutic agents. Conditional patched mutant tumor cells were treated with increasing concentrations of the chemotherapeutic agents vincristine alone or in combination with 10 nMol/L BI-2536. Cells were cultured for 48 hours, pulsed with 3H-Td, and harvested for analysis of 3H-Td incorporation at 66 hours.

Determination of mutation frequencies in cells treated with chemotherapy drugs following caspase inhibition. TK6 cells were incubated with no inhibitor or 10 μM QVD then treated with the following drug doses: 300 ng/ml TRAIL, 0.7 μM cisplatin, 0.5 μM temozolomide, 3 nM doxorubicin, 0.5 nM SN38 or 0.07 nM vincristine. (a) Caspase activity was assessed by luminescent detection of Caspase-3/-7 Glo reagent after 5 h. After 24- h treatment, (b) clonogenicity assays were performed to determine the proportion of cells maintaining clonogenic competency after treatment, whereas (c) surviving cells were grown in 6TG to select for the emergence of any HPRT mutants. (d) Clonogenicity and (e) HPRT mutation assays were repeated in CASP3/7 DKO lines in the same manner. Error bars represent mean±S.E.M. from at least three independent experiments. Two-sided T-tests were used to calculate P-values.

Discrimination of micronuclei induced by EMS and VCR in V79-hCYP2E1-hSULT1A1 cells as CENP-B negative or positive. The cells were treated with EMS (5 mM) or VCR (5 nM) for 6 h, followed by a recovery period of 18 h. They were stained for CENP-B (green) and β-tubulin (red) by the immunofluorescence assays, as described in Section 2.5. DNA was stained with DAPI (blue). The vertical and horizontal arrows indicate CENP-B-negative and CENP-B-positive micronuclei, respectively.

| In vitro |
Vincristine inhibits net addition of tubulin dimers at assembly ends of steady-state microtubules with Ki of 85 nM. [1] At low concentrations, Vincristine stabilizes the spindle apparatus resulting in failure of the chromosomes to segregate leading to metaphase arrest and inhibition of mitosis. At higher concentrations, Vincristine may disrupt and induce total depolymerization of microtubules. [2] Vincristine induces apoptosis in tumor cells and inhibits SH-SY5Y cell proliferation with IC50 of 0.1 μM. Vincristine induces mitotic arrest and promots the expression of caspase-3 and -9 and cyclin B, while decreasing the expression of cyclin D. [4] Vincristine induced neurotoxicity is caused by interference with microtubule function, which results in blockage of axonal transport and thus in axonal degeneration. [5] |

| In vivo | Vincristine (3 mg/kg) administrated by a single i.p. injection to mice bearing bilateral subcutaneous xenografts Rh12 or Rh18, induces mean growth delay of >120 and >52 day, and repopulating fractions of 0.06% and 5%, respectively. [6] Vincristine acts on subcutaneous colon 38 tumors in mice by host cell-mediated vascular effects as well as by direct tubulin-mediated cytotoxicity. Vincristine (5 mg/kg) reduces tumor blood flow of tumors by nearly 75% . [7] |

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).
