Article Title: Melatonin Modulation of Radiation-Induced Molecular Changes in MCF-7 Human Breast Cancer Cells
doi: 10.3390/biomedicines10051088
Figure Lengend Snippet: Effects of melatonin and radiation on breast cancer miRNA expression microarray. Total RNA from MCF-7 cells was extracted 4 h after radiation, reverse transcribed and used for RT-PCR analysis using Human Breast Cancer microarray (MIHS-109ZA). ( a – c ) Heatmaps of relative normalized expression between different treatments ( a ) M vs. C; ( b ) R vs. C; ( c ) M + R vs. C; ( d ) Bar chart of relative normalized expression (ΔCt) of selected miRNAs. a: miR20a; b: miR-20b; c: miR-17; d: miR-141; e: miR-15a; f: miR-19a; g: miR29a; h: miR-93; i: miR-10b. C: Control; M: Melatonin pre-treated cells (1 nM); R: Radiated cells (8 Gy); M + R: Melatonin pre-treated and radiated cells.
Article Snippet: We next analyzed the influence of melatonin on the expression of multiple genes and miRNAs involved in breast cancer using a gene microarray (Human Breast Cancer RT 2 Profiler TM PCR Array) and a Human Breast Cancer miRNA microarray (MIHS-109ZA, Qiagen, Germantown, MD, USA).
