Purpose: To test the effect of Cryptotanshinone (CPT), a natural compound isolated from the plant Salvia miltiorrhiza Bunge, on human leukemic cell lines (HL-60). Methods: HL-60 cells were treated with CPT. Cell growth inhibition (%) was quantitated using MTT assay. Apoptosis detection with Annexin V-FITC/propidium iodide staining was followed by flow cytometry. Caspase-3, caspase-8, and caspas...

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) has the ability to selectively trigger cancer cell apoptosis and can be used as a target for tumor therapy. However, gastric cells are usually insensitive TRAIL so reducing this drug resistance may improve treatment of cancer. In study, we Cell Counting Kit-8 (CCK-8) 5-ethynyl-2′-deoxyuridine (EdU) experiments determine effects 5-f...

abstractthe purpose of this investigation was to evaluate the antiproliferative and apoptogenic mechanistic studies of methanol extract of anthocephalus cadamba (meac) on dalton’s lymphoma ascites (dla) cells treated mice. determination of antiproliferative activity was performed by using different dla cells (2×106 cells, i.p.) inoculated mice groups (n=12). groups were treated for 14 consecuti...

22β-hydroxytingenone (22-HTG) is a quinonemethide triterpene isolated from Salacia impressifolia (Miers) A. C. Smith (family Celastraceae), which has been used in traditional medicine to treat variety of diseases, including dengue, renal infections, rheumatism and cancer. However, the anticancer effects 22-HTG underlying molecular mechanisms melanoma cells have not yet elucidated. The present s...

Primula auriculata (Tootia) is one of the most important local medicinal plants in Hamedan district, Iran. To investigate cytotoxicity and apoptosis induction of crude methanolic extract and different fraction of it we compared several methods on HT-29 human colon Adenocarcinoma cells. Cancer cell proliferation was measured by 3-(4, 5‑dimethylthiazolyl)-2, 5‑diphenyl‑tetrazolium bromide (MTT) a...

The aim of this study was to investigate the effect TiO2/N-succinyl-chitosan composite (TiO2/ NSCS) photodynamic therapy (PDT), while considering effects various light sources on activation photosensitizer. methyl thiazolyl tetrazolium assay used examine cell survival rate cells. results showed that glioma strain (U251) most sensitive cancer TiO2/NSCS. When concentration TiO2/NSCS between 0 and...

Datura innoxia is an important species of Solanaceae family with several purposes in folk medicine. This study intends to explore the cytotoxic effect D. on various cancer cell proliferation. ethanolic extract’s progression cycle and induction apoptosis were investigated by flow cytometry. Further, real-time PCR was employed confirm initiation. In addition, active phytochemicals identified gas ...

To evaluate the in vitro anticancer activity and to investigate the mechanism of action of a thiophene heterocyclic compound, [3-Amino-5-[(2,6-dimethylphenyl)amino]-4-(phenylsulfonyl)-2-thienyl](4-fluorophenyl)methanone (APTM) against human colon cancer HCT116 cells. Sulforhodamine B assay and colony formation assay for cell proliferation assay; propidium iodide (PI) staining for cell cycle pro...

Purpose: In retinal endothelial cells, homocysteine (Hcy) activates matrix metalloproteinase (MMP)-9, which results in apoptosis. This study investigated these effects of Hcy human trabecular meshwork cells (HTMC).Methods: HTMC cultures using 5 mM low or 20 high glucose (HG)-containing media were exposed to 100 μM for 3 days. Cell viability was assessed with the MTT (3-[4, 5-dimethylthiazol-2-y...

Background and Aims: Nickel oxide nanoparticles (NiO-NPs) are one of the most used nanoparticles, especially as photosensitizers. Although some studies evaluate their toxicity in liver, information about at cellular molecular levels is still controversial. In present study, it was aimed to investigate vitro toxic potentials NiO-NPs (average size 15.0 nm) liver (HepG2) cell line. Methods: were ...
