Elevated expression of the drug efflux transporter ABCG2 seems to correlate with multidrug resistance of cancer cells. Specific COX-2 inhibitor celecoxib has been shown to enhance the sensitivity of cancer cells to anticancer drugs. To clarify whether ABCG2 inhibition is involved in the sensitizing effect of celecoxib, we investigated whether the expression of ABCG2 in breast cancer cell lines ...

Background: The induction of bystander effect via ionizing radiation has been well proven. However, few studies have investigated the bystander effect following non-ionizing radiation, such as ultrasound waves. Here, the bystander effect after different sonication times on human melanoma cell line (A375), is evaluated by assessing cell viability and apoptosis. Materials and Methods: The cells w...

the purpose of this research was to investigate the effect of mir-429 ectopic over-expression on u251 glioblastoma cell line. it has been shown that mir-429 could target bmk1 and reduce glioma cells invasion. we cultured u251-mir-429 cells and observed changes in their morphology for 14 days. they seemed to become wider with expanded cytoplasm and go on differentiation. neuronal (nefm, nse and ...

Background: It seems that Vinca. herbacea has an anti-tumor effect. Here, the immunotherapeutic effect of this compound is assessed against human ovarian cancer (SKOV3) cells because of the high incidence of this tumor in women. Materials and Methods: The cytotoxic activity of V. herbacea extract against human ovarian cancer (SKOV3) cells was determined by MTT assay. The apoptosis-inducing pote...
