There is a major concern that exposure to titanium dioxide (TiO2) nanoparticles (NPs) can have degrading effects on human health as well as mammary gland because of the increased use in numerous sorts of nanotech-based health care and food merchandise. Also, there is a scarcity in NP toxicity studies on the mammary gland; therefore, the aim of the present study was to compare toxicity caused by nano- and bulk-phase TiO2 particles on the human mammary gland in vitro. In comparison to bulk-TiO2 particles, nano-TiO2 cause a significant ( p < 0.05) reduction in viability and increased reactive oxygen species generation in the human mammary epithelial cells after a dose- (1, 2, 5, 10, 20, 50, and 100 µg/mL) and time (6, 12, 24, and 48 h)-dependent exposure. Further, an increase in genotoxicity in the mammary epithelial cells was observed as percent tail DNA and comet area was increased significantly ( p < 0.05) at 12 h of exposure (10 and 100 µg/mL) with nano-TiO2. The scanning electron microscopic examination showed that a 50 µg/mL dose of both nano-TiO2 and bulk-TiO2 particles cause morphological changes and retarded growth pattern of mammary epithelial cells at 12 h. Moreover, a significant ( p < 0.05) increase in apoptosis at 10 µg/mL and necrosis at 50 µg/mL concentrations of nano-TiO2 in comparison to bulk-TiO2 was observed in mammary epithelial cells. Finally, we can conclude that the toxicity caused by nano-TiO2 particles on the human mammary gland cells was comparatively higher than the bulk-TiO2 particles.

Analyzing the morphological and ultrastructural features of the mammary gland during the menstrual cycle, the authors observed that in the proliferative phase, the mammary gland consisted of few developed lobules and presented a relative absence of mitotic figures. In this phase, the great majority of the epithelial cells contained small, dark, irregular, rich heterochromatinic nuclei. The mammary stroma showed similar findings, presenting dense connective tissue with few enhanced fibroblasts. During the secretory phase, the lobules were well developed and mitotic figures were usually observed. In this phase, the great majority of the ephitelial cells presented clear voluminous, rich euchromatinic nuclei; the stroma consisted of fibroblasts with voluminous nuclei full of euchromatin. There are evident modifications of the mammary tissue according to the phase of the menstrual cycle. The morphological and ultrastructural modifications indicate higher metabolical and mitotic activities during the secretory phase.
