BACKGROUND Gene transcripts specifically expressed in a particular cell type (cell-type specific gene markers) are useful for its detection and isolation from a tissue or other cell mixtures. However, finding informative marker genes can be problematic when working with a poorly characterized cell type, as markers can only be unequivocally determined once the cell type has been isolated. We pro...

background- cd24 is a cell adhesion molecule that has been implicated in metastatic tumor progression cells. our aim was clarify correlation between cd24 expression and camp:cgmp ratio in murine colorectal cancer cell line (ct26) after using cholera toxin. materials and methods- the ct26 cells were cultured in microtubes for assaying camp and cgmp; also the cells were cultured in flasks for ass...

background: oct4b1, a novel variant of oct4, is expressed in cancer cell lines and tissues. based on our previous reports, oct4b1 appears to have a crucial role in regulating apoptosis as well as stress response [heat shock proteins (hsps)] pathways. the aim of the present study was to determine the effects of oct4b1 silencing on the expression of high molecular weight hsps in three different h...
