Background & objectives: Breast cancer is one of the most important causes of cancer deaths especially in developing countries. However, some synthetic compounds such as thiosemicarbazone and its metal derivatives can play a very significant role in reducing the death rate from cancer. The aim of this study was to investigate alterations in the expression of BRCA1, p53 and Bcl-2 genes in breast cancer cell line.
Methods: In this study, the effect of pyrazole derivative of thiosemicarbazone (T) as well as T-bound iron oxide magnetite nanoparticles (T/ Fe₃o₄ np) were investigated on expression changes of Bcl-2, BRCA1 and p53 in MCF-7 cells. For this purpose, the toxicity of the compounds was first measured using the MTT reaction for 24 hr. Then, the mRNA expression levels were evaluated using real-time PCR reaction.
Results: The results showed a high toxicity for the nano-pyrazole derivative of thiosemicarbazone magnetite so that; the fatality rate for treated thiosemicarbazone magnetite derivative cells was much higher than the compound without any nanoparticle. Also, real-time polymerase chain reaction analysis of gene expression indicated a high effect of the derivative on increasing the expression levels of BRCA1 and p53 genes and also decreasing the Bcl-2 gene expression of Bcl-2.
Conclusion: The use of anticancer compounds like thiosemicarbazone which bound to iron oxide nanoparticles would increase the toxicity of the anticancer compounds along with enhancment of delivery of them with high solubility to target tissue.

Endometriosis is a long-term health condition that is known as a significant factor in women's infertility issues nowadays. Since many factors contribute to the development of this disease and because diagnosis is difficult and typically happens late in the progression of the disease, early detection is especially crucial. Extracellular micro vesicles called exosomes have diverse biological molecules and can alter the behavior of recipient cells, influencing angiogenesis, fibrosis, and inflammation. Exosomes are significant in cell communication and could act as new biomarkers for early detection of endometriosis. Hence, exploring and comprehending the impact of exosomes on the development of endometriosis can create opportunities for studying potential diagnostic biomarkers and targeted therapeutic interventions to prevent the advancement of the condition. This article delves into new approaches to diagnose and treat endometrial disorders by highlighting the various functions of exosomes in endometriosis.
