Objectives:
Impact of vitamin D (1, 25 dihydroxy vitamin D3) (calcitriol) in the regulation of different genes has been investigated in different cancers including breast cancer (BC).
Material and Methods:
In the current study, we analyzed the expression levels of the CYP24A1 and SIRT7 genes and their relationship with patients’ clinical data in BC using polymerase chain reaction (PCR). Afterward, we tend to analyze the effect of vitamin D on the expression of these genes in cell lines (MCF7 and MDAMB231) to find the regulatory role of vitamin D in BC.
Results:
Our results showed that the CYP24A1 and SIRT7 were increased by vitamin D treatment and CYP24A1 levels were related to tumors stages (p = 0.03) and up-regulation of CYP24A1, SIRT7 had the distinguish potential for breast cancer detection based on their receiver operative characteristic (ROC) curve results (0.77, 0.84, respectively).
Conclusion:
In summary, CYP24A1, SIRT7 may be used as a possible diagnostic biomarker in BC treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
