A 30 years-old man was administrated with dizziness and fatigue for half month, and the big toe on his left foot got the prolonged bleeding of wound complicated with fever 7 days before the admission. The physical examination (PE) discovered that the case suffered from the anemic appearance, lower
OBJECTIVE
To investigate molecular mechanism of tanshinone II A inducing differentiation and apoptosis in acute promyelocytic leukemia NB4 cells.
METHODS
NB4 cells were cultured in vitro and treated with tanshinone II A and observed cellular morphology, cell category and the cellular proliferation.
OBJECTIVE
To determine the anti-proliferative effect of Tanshinone II A (TAT) on leukemia K562 cell line and its mechanism.
METHODS
The proliferation of K562 cell line was detected by MTT assay. The morphological changes of the cells were examined with light microscope. The cell apoptosis was
The aim of this study was to investigate whether Tanshinone II A (Tan II A) can induce human acute promyelocytic leukemia (APL) cells to differentiate or not in primary culture. The APL cells from 5 cases were cultured respectively with Tan II A at the concentration of 0.5 microgram/ml for 7 days in
OBJECTIVE
To study the anti-tumor effect of tanshinon II A, tetrandrine, honokiol, curcumin, oridonin and paeonol on leukemia cell lines SUP-B15, K562, CEM, HL-60 and NB4.
METHODS
To study the anti-tumor effect of tanshinone II A, tetrandrine, honokiol, curcumin, The leukemia cell lines were exposed
OBJECTIVE
To observe the effects of Tanshinone II A (Tan II A) on acute promyelocytic leukemia (APL) characterized by resistance to all-trans retinoic acid (ATRA) and arsenic trioxide (ATO).
METHODS
A 21-year-old male patient with relapsed APL, who previously received the maintenance therapy with
OBJECTIVE
To investigate APL cell differentiation induced by tanshinone II (Tan II A) and its molecular mechanism.
METHODS
In vitro incubation of NB4 cells with Tan II A at the concentration of 0.5 microg/ml for 5 days, the cell differentiation was observed by cytomorphology, and nitroblue
OBJECTIVE
To evaluate the synergism of Tanshinone II A (Tan II A) and arsenic trioxide (As2O3) on the apoptosis of retinoic acid resistant acute promyelocytic leukemia (APL) cell line (MR2), and to investigate its effect on the expression of P-glycoprotein (Pgp) of MR2 cells.
METHODS
As2O3 was added
OBJECTIVE
To evalutate the synergistic effects of Tanshinone II A combined with all-trans retinoic acid (ATRA) on the differentiation and apoptosis of human acute promyelocytic leukemia (APL) cell line (NB4).
METHODS
The NB4 cells were treated with 0.5 microg/ml Tanshinone II A combined with 0.5
OBJECTIVE
To investigate the effect of tanshinone II A on the procoagulant activity (PCA) of human umbilical vein endothelial cells (HUVEC) induced by acute promyelocytic leukemia (APL) cell line NB4 cells.
METHODS
The HUVEC were incubated for 6, 12, and 24 hours in different tanshinone II A
Tanshinone II-A is a derivative of phenanthrene-quinone isolated from Salvia miltiorrhiza BUNGE, a traditional herbal medicine that is known to induce antiinflammatory, anti-oxidative and cytotoxic activity. We have examined cellular effects of Tanshione II-A on HL60 human promyelocytic leukemic
Fourteen constituents were isolated from the roots of Salvia miltiorrhiza f. alba. Two of them were new compounds and were named 1,2,15,16-tetrahydrotanshiquinone (I) and tanshinaldehyde (II). The others were identified as Ro-090680 (III), dihydroisotanshone I (IV), danshexinkun B (V), miltirone
Tanshinone I (T1) and tanshinone II (T2) are the major diterpenes isolated from Danshen (Salvia miltiorrhiza Bunge). Three human lung adenocarcinoma cell lines, A549, CL1-0, and CL1-5, were treated with T1 and T2 for the in vitro antitumor test. Results showed that T1 was more effective than T2 in
