Abstract

Breast cancer in women is the second most commonly cancer, after skin cancer. The percentage of mortalityrisk for breast cancer is 1 in 37 women (2.7%), which makes breast cancer represent the second cause of cancerdeath in women. Recently, new research based on previously published work in systemic chemotherapy andendocrine therapy field, have improved the incidence rates. The quinonic nucleus is common to many naturaland synthetic products associated with anticancer and antibacterial activities, these compounds are typicallyDNA-intercalating agents. The Class I Homeobox genes (HOX in human and hox in mouse) control embryonicdevelopment and specific determination of positional identity anteroposterior axis of the human body. The HOXgenes, are 39 transcription factors related to morphological, physiological disease. It has been demonstratedthat any deregulation into the network is able to induce neoplastic transformation. Particularly, HOXC locuscollaborating with lncRNA HOTAIR play a key role in breast cancer. In this study, our group evaluated the chemical and metabolic stability of new anticancer molecule 5H-pyro[3,2-a] phenoxazin-5-one (PPH). In a recent paper, we have already demonstrated that a new and potent anticancersynthetic iminoquinone, the 5H-pyrido[3,2-a]phenoxazin-5-one (PPH), is able to inhibit a large number oflymphoblastoid and solid-tumor-derived cells at submicromolar concentrations. Based on our previous research, we decided to analyze the cytotoxic effect and capability of PPH to control thelncRNA HOTAIR and HOXC locus gene expression in human breast cancer cells MCF-7, in order to demonstrateits role like potential new breast cancer antitumor drug.
