CDNA microarray analysis of miR-1 transfected HeLa and NPC-TW01 cells


ABSTRACT: To investigate the mechanisms of miR-1 inducing apoptosis, we performed cDNA expression microarray analysis to identify the candidate miR-1 regulating genes that are involved in apoptosis. NPC-TW01 cells were transfected with miR-1 or miR-negative control for 40 hours, their total RNA were isolated from the cells and hybridized to an Agilent human whole genome oligo 4 x 44 K microarray. HeLa cells were transfected with miR-1 or miR-negative control for 40 hours, their total RNA were isolated from the cells and hybridized to an Agilent human whole genome oligo 4 x 44 K microarray.

<h4>Background</h4>MiR-1 (microRNA-1) has been used as a positive control in some microRNA experiments. We found that miR-1 transfection of nasopharyngeal carcinoma cells reveals a typical apoptotic process as shown by time-lapse microscopy so we investigated the mechanisms of miR-1 inducing apoptosis.<h4>Methods</h4>To confirm that miR-1 induces apoptosis, we used Annexin V and TUNEL staining and caspase assay. To determine that miR-1 directly targets genes that involve in apoptosis, we analyze  ...[more]
