Abstract
Introduction The microenvironment of solid tumors such as breast cancer is heterogeneous and complex, containing different types of cell, namely, cancer stem cells and immune cells. We previously reported the immunoregulatory behavior of the human immune cell in a solid tumor microenvironment-like culture under serum starvation stress for 96 h. Here, we examined the effect of this culture-derived solution on breast cancer development in rats. Method Ninety-six-hour starved PBMCs supernatant (96 h-SPS) was collected after culturing human PBMCs for 96 h under serum starvation condition. Breast cancer stem cells, LA7 cell line, was used for in vitro study by analyzing gene expression status and performing cytotoxicity, proliferation, scratch wound healing assays, followed by in vivo tumor induction in three groups of mature female Sprague Dawley rats. Animals were treated with 96 h-SPS or RPMI and normal saline as control, n = 6 for each group. After biochemical analysis of iron, lactate, and pH levels in the dissected tumors, Ki67 antigen expression, angiogenesis, and necrosis evaluation were carried out. Metabolic-related gene expression was assessed using RT-qPCR. Moreover, 96 h-SPS composition was discovered by Nano-LC-ESI-MS/MS. Results 96 h-SPS solution reduced the LA7 cell viability, proliferation, and migration and Gch1 and Spr genes expression in vitro (p< 0.05), whereas stemness gene Oct4 was upregulated (p< 0.01). The intracellular lactate was significantly decreased in the 96 h-SPS treated group (p = 0.007). In this group, Gch1 and Spr were significantly downregulated (p< 0.05), whereas the Sox2 and Oct4 expression was not changed significantly. The number of vessels and mitosis (Ki67+ cells) in the 96 h-SPS-treated group was significantly reduced (p = 0.024). The increased rate of necrosis in this group was statistically significant (p = 0.04). Last, proteomics analysis revealed candidate effectors' components of 96 h-SPS solution. Conclusion 96 h-SPS solution may help to prevent cancer stem cell mediated tumor development. This phenomenon could be mediated through direct cytotoxic effects, inhibition of cell proliferation and migration in association with reduction in Gch1 and Spr genes expression, angiogenesis and mitosis rate, and necrosis augmentation. The preliminary data obtained from the present study need to be investigated on a larger scale and can be used as a pilot for further studies on the biology of cancer development.

Abstract
Down-regulation of stemness genes expression is important in differentiation therapy against cancer stem cells (CSCs). The aim of this study was to evaluate the Oct4 , Sox2, Nanog, and C-myc expression in rat breast cancer stem cells (LA7) which treated with human ovarian follicular fluid (FF), replicative senescent fibroblast culture supernatant (P14), and 16 h serum starved fibroblast supernatant (16 h-SFS). The cells were exposed to these biological fluids for 24 h, 72 h, and 7 days. Stem-loop RT-qPCR assay was used to quantify the expression of above mentioned genes. Results showed that FF had the least cytotoxic effect on the LA7 cells. Except for Nanog gene, exposure of LA7 cell line to 16 h-SFS and P14 decreased significantly expression of the three other genes after 24 h (P < 0.05). Nanog and Sox2 genes expression was also decreased in LA7 cells which have been already treated with FF for 24 h. Moreover, compared to the control solution, the expression of Oct4 increased significantly after 7 days exposure to FF (P < 0.05). Annexin V-PE /7-AAD-, acridine orange/ethidium bromide staining and doubling time assays revealed apoptosis and necrosis induction by these biological fluids in LA7 cells. Moreover, in an in vitro model of metastasis assay, i.e., scratch test, these fluids exhibited anti-LA7 migration activity which culminated in 16 h-SFS treated cells. Generally, this study showed that FF, 16 h-SFS, and P14 have positive effects on down-regulation of Nanog, Oct4, Sox2 and C-myc expression, and consequently can increase the differentiation of breast cancer stem cells. For the first time, this study provided some evidence indicating that some biological fluids have potential to differentiate the CSCs, show anti- survival, growth-, and cell migration activity.

Abstract
Cancer cell lines have become a reliable tool in genetic and biochemical studies of breast cancer. Here, we described the behavior and novel molecular characterization of two cell lines derived from DMBA-induced rat mammary tumor, LA7 and RBA. LA7 cells have been identified as myoepithelial cells with stem cell properties, whereas the RBA cell line are epithelial cells that present mutational activated H-Ras, but are much less known. We evaluated the proliferation rate and molecular markers, several signaling pathways status related to proliferation, survival, inflammation, and apoptosis, as well as migration capacity, global DNA methylation levels, and stem cells populations. In fact, we found the A/T transversion in the c-Ha-Ras codon 61 as the activator mutation origin described in RBA cells. LA7 and RBA cells showed a high proliferation rate associated with overexpression of Cyclin D1, and resistance to apoptotic signals due to lack of expression of Bad. Moreover, neither of these two cell lines expressed steroid receptors, but they showed high migration capacity, all in accordance with an aggressive phenotype. We found global DNA methylation levels in LA7 and RBA cells lower than reference tissues analyzed, in addition to the presence of different stem cells populations in RBA cell line that differed in the expression of CD44 and CD24. These results revealed a malignant behavior associated with cancer stem cell phenotype. Since this profile is similar to a human triple-negative basal-like tumor, their extensive characterization presented herein increases their value as a good in vitro model. J. Cell.
