background: hla-g is a nonclassical hla class i molecule which, when elevated in tumor cells, is one of the main factors involved in tumor evasion of immune responses including nk and t cells. objective: to evaluate the effect of hla-g downregulation on nk cell cytotoxicity in tumor cell lines. methods: the expression level of hla-g was measured by real-time pcr and flowcytometry after transfec...

objective: mir-302-367 is a cluster of polycistronic micrornas that are exclusively expressed in embryonic stem (es) cells. the mir-302-367 promoter is functional during embryonic development but is turned off in later stages. motivated by the cancer stem cell hypothesis, we explored the potential expression of mir-302 in brain tumor cell lines. materials and methods: in the present experimenta...

Isolation of some potent anti-tumor compounds from medicinal plants has motivated researchers to screen different parts of plant for their anti-tumor effects. It has been reported that several species of conifers posses’ cytotoxic activities on some tumor cell lines. Here branchlets and berries of Juniperus foetidissima and J. sabina were collected, dried and ethanol extracts of them obtain...

the cytotoxic activity of ethanolic extracts of thymus vulgaris, thuja orientalis and achillea millefolium was investigated on various growing tumor cell lines. mtt colorimetric assay was used for measuring the inhibition of cell proliferation. all of the three extracts showed a relatively dose-dependent inhibition of proliferation of human breast cancer (sk-br-3, mda-mb-435) and leukemia (u937...

the cytotoxicity activity of the essential oils from the leaves of achillea wilhelmsii c. koch were studied on six tumor cell lines and a normal cell line w
