Abstract
BACKGROUND Mammary tumors are one of the major malignancies seen in cats. Researchers have indicated the similarity between the epidemiological and clinicopathological patterns of feline mammary tumors and human breast cancer (HBC). In recent years, the investigation of trace elements in cancer tissues becomes prevalent in HBC due to the role of these elements in biochemical and physiological processes. This study, it is aimed to evaluate some trace elements in feline mammary tumors according to clinical and pathological findings. METHODS A total of 60 tumoral masses from 16 female cats with mammary tumors were included in the study. The study groups were formed according to histopathology as malignant epithelial tumor (MET; n = 39) and hyperplasia and dysplasia (H&D; n = 21). Copper (Cu), Iron (Fe), Magnesium (Mg), Manganese (Mn), Selenium (Se) and Zinc (Zn) trace elements in mammary tissues were analyzed by using an inductively coupled plasma-optical emission spectrophotometer. RESULTS The mean age and weight of the cats were 11.75 ± 0.75 years and 3.35 ± 0.21 kg; respectively. Eleven of 16 cats were intact whereas the rest of them had been spayed. Metastases were observed in 10 cats. Tissue Mg level in group MET was significantly higher than in group H&D (P < 0.01) while the other elements had not significant differences between the groups. In group MET, analyzed elements were not statistically significant related to the inflammation, ulceration and invasion to the peripheral muscle (P > 0.05). However, tissue Fe level was significantly higher in T2 than in T3 (P < 0.05). The mean levels of tissue Fe, Mg and Mn had significant differences related to histological grading as P < 0.01, P < 0.05 and P < 0.001; respectively. A mild to severe correlation was found between tissue Zn and Se, Cu, Fe, Mg, and Mn levels. CONCLUSION Tissue Mg and some trace elements were evaluated in feline mammary tumours in regard to various clinicopathological parameters. Tissue Mg level was sufficient to differentiate the malignant epithelial tumors from hyperplasia and dysplasia. However, Mn and Se tended to distinguish different tumor types. Tissue Fe, Mg and Mn had significant differences related to histological grading. Also, the Fe level was significantly higher in T2 than in T3 and Zn level tended to be higher in T3 than in T1. It was concluded that Mg, Se, Mn, Fe, Cu and Zn provided useful information on the pathogenesis of feline mammary tumors. Further research is needed on the tissue and serum concentrations of trace elements which may provide valuable information for the disease prognosis.

Abstract
Breast cancer has become the most common cancer worldwide. Despite the major advances made in the past few decades in the treatment of breast cancer using a combination of chemotherapy, endocrine therapy, and immunotherapy, the genesis, treatment, recurrence, and metastasis of this disease continue to pose significant difficulties. New treatment approaches are therefore urgently required. Zinc is an important trace element that is involved in regulating various enzymatic, metabolic, and cellular processes in the human body. Several studies have shown that abnormal zinc homeostasis can lead to the onset and progression of various diseases, including breast cancer. This review highlights the role played by zinc transporters in pathogenesis, apoptosis, signal transduction, and potential clinical applications in breast cancer. Additionally, the translation of the clinical applications of zinc and associated molecules in breast cancer, as well as the recent developments in the zinc-related drug targets for breast cancer treatment, is discussed. These developments offer novel insights into understanding the concepts and approaches that could be used for the diagnosis and management of breast cancer.

Abstract
Zn2+ dyshomeostasis is an intriguing phenomenon in breast and prostate cancers, with breast cancer cells exhibiting higher intracellular Zn2+ level compared to their corresponding normal epithelial cells, in contrast to the low Zn2+ level in prostate cancer cells. In order to gain molecular insights into the zinc homeostasis of breast and prostate cancer cells, this study profiled the expression of 28 genes, including 14 zinc importer genes (SLC39A1-14) which encode ZIP1-14 to transport Zn2+ into the cytoplasm, 10 zinc exporter genes (SLC30A1-10) which encode ZnT1-10 to transport Zn2+ out of the cytoplasm and 4 metallothionein genes (MT1B, MT1F, MT1X, MT2A) in breast (MCF10A, MCF-7, MDA-MB-231) and prostate (RWPE-1, PC3, DU145) cell lines in response to extracellular zinc exposures at a mild cytotoxic dosage and a benign dosage. The RNA samples were prepared at 0 min (T0), 30 min (T30) and 120 min (T120) in a time course with or without zinc exposure, which were used for profiling the baseline and dynamic gene expression. The up-regulation of MT genes was observed across the breast and prostate cancer cell lines. The expression landscape of SLC39A and SLC30A was revealed by the qRT-PCR data of this study, which sheds light on the divergence of intracellular Zn2+ levels for breast and prostate cancer cells. Taken together, the findings are valuable in unravelling the molecular intricacy of zinc homeostasis in breast and prostate cancer cells.
