The determination of pharmacological activity of the anti-skin carcinoma activity of test example 2 Ramulus et folium taxi cuspidatae
The present invention is take A431 application on human skin squamous cell JEG-3 as object of study, take present active anticancer to measure more mtt assay, the trypan blue living cells is refused the method for dying, the cellular morphology observational method is come Ramulus et folium taxi cuspidatae component to be measured is carried out the research of anti-skin carcinoma activity before and after Flow Cytometry Assay apoptosis and the medication, but whether preliminary study Ramulus et folium taxi cuspidatae extract part has the effect of In Vitro Anti cutaneous squamous cell carcinoma cell-proliferation activity, the size of its effectiveness, pharmaceutically-active concentration relationship, and whether induce the A431 apoptosis, determine whereby the activity group (one-tenth) of cutaneous squamous cell carcinoma effect sensitivity is divided, lay the foundation for the medicinal function cosmetics of further developing anti-skin carcinoma become potential ancillary drug as cutaneous squamous cell carcinoma.
Test method:
1.1.1 cell culture
Cell: people's epidermis squamous cell carcinoma strain A431.
Cellar culture: be incubated in the DMEM culture medium that contains 10% hyclone (FBS), place 37 ℃, 5%CO 2Cell culture incubator in, changed liquid once in per two days, observe under the inverted microscope, when cell fusion reaches 80% left and right sides, go down to posterity, 0.25% pancreatin solution digestion, the cell counting count board counting is with every hole inoculation 2 * 10 5Individual/ml cell is inoculated in 6 orifice plates, when it enters the logarithmic growth after date, adds respectively different pharmaceutical and processes, and detects corresponding index.
Method is observed medicine to the growth inhibited effect of tumor cell
1.1.2.1 experiment grouping
The Ramulus et folium taxi cuspidatae active component is to the lethal effect of A431:
Each component of Ramulus et folium taxi cuspidatae adopts respectively 1.25 * 10 in this test example -2, 3 * 10 -3, 1 * 10 -4, 5 * 10 -5, 2.5 * 10 -55 concentration levels of mg/ml, be 48h action time.
1.1.2.2 inoculating cell:
The trophophase cell of taking the logarithm after 0.25% trypsinization, is diluted to single cell suspension with the DMEM culture fluid that contains 10% FBS, with every hole 5 * 10 3Individual being inoculated in 96 well culture plates, every hole 200 μ l are in 37 ℃, 5% CO 2Incubator in cultivate.
After 1.1.2.3 cell is fully adherent, serum-free culture 24h synchronization, the every hole of experimental group add respectively contain different pharmaceutical culture fluid 100 μ l, make final concentration be respectively preset concentration, adjusting every hole final volume is 200 μ l, establishes 6 multiple holes for every group, every culture plate stays a hole not add cell, only add culture fluid, be made as the zeroing hole, continue in incubator, to cultivate.
1.1.2.4 every hole adds 5mg/ml MTT solution 20 μ l, 37 ℃ hatch 4 hours after, every hole adds three liquid of 80 μ L, incubated overnight.
1.1.2.5 with the zeroing of zeroing hole, enzyme-linked immunosorbent assay instrument detects every hole absorbance (Absorbance, A value) at 570nm wavelength place, calculates cells survival rate (Survivil Rate, SR) and suppression ratio (Inhibitory Rate, IR).
Survival rate (SR)=experimental port A value/control wells A value * 100%
Suppression ratio (IR)=(control wells A value-experimental port A value)/control wells A value * 100%.
1.1.2.6 the suppression ratio that the time is abscissa, respectively organize cell is vertical coordinate, draws cell growth curve.
It is active that the trypan blue living cells refuses to dye the method counting cells
1.1.3.1 experiment grouping:
Each component of Ramulus et folium taxi cuspidatae adopts respectively 1.25 * 10 in this test -2, 3 * 10 -3, 1 * 10 -4, 5 * 10 -5, 2.5 * 10 -55 concentration levels of mg/ml.
