The Relationship Between Polymorphism Vitamin D Fok-1 Receptor Gene (RS2228570) and Vitamin D Plasma Levels Against Cell Proliferation (KI-67) in Breast Cancer

Introduction

Breast cancer is a significant health concern for women worldwide, and understanding the underlying factors that contribute to its development is crucial for the development of effective treatment strategies. Vitamin D and its receptors have been identified as playing a crucial role in the development of breast cancer. One important aspect of this study is the FOK-1 polymorphism, a genetic variation in vitamin D receptors that has the potential to produce protein products with different lengths. This polymorphism is located in the start codon area in EXON 2, marked by base conversion (C> T), and has been associated with changes in cellular signals emitted by vitamin D, affecting the growth and progression of tumor cells. The KI-67 indicator is used to measure cell proliferation, which is a critical factor in the development of breast cancer.

The Importance of Vitamin D in Breast Cancer

Vitamin D has been shown to play a significant role in the development of breast cancer, with studies suggesting that it may have a protective effect against the disease. Vitamin D receptors are present in breast tissue, and the activation of these receptors by vitamin D has been shown to inhibit the growth of breast cancer cells. However, the relationship between vitamin D levels and breast cancer risk is complex, and further research is needed to fully understand the mechanisms involved.

The Role of FOK-1 Polymorphism in Breast Cancer

The FOK-1 polymorphism is a genetic variation in the vitamin D receptor gene that has been associated with changes in cellular signals emitted by vitamin D. This polymorphism has been shown to affect the growth and progression of tumor cells, and may play a role in the development of breast cancer. The FOK-1 polymorphism is located in the start codon area in EXON 2, marked by base conversion (C> T), and has the potential to produce protein products with different lengths.

Research Objectives

The primary objective of this study was to investigate the relationship between polymorphism Vitamin D Fok-1 receptor gene (RS2228570) and vitamin D plasma levels with cell proliferation (KI-67) in breast cancer patients. This study aimed to provide insights into the genetic and biochemical factors that contribute to the development of breast cancer.

Methodology

This study involved blood sampling from 50 newly diagnosed breast cancer patients who had not undergone chemotherapy. DNA isolation and gene amplification were carried out using PCR techniques, while polymorphism Vitamin D Fok-1 receptor gene was tested through PCR-RFLP techniques. The level of 25 (OH) D was determined using the ELISA method. The relationship between variables was tested using the Fisher Exact test with a p-value <0.05 as a significant limit.

Results

The results of this study showed that the frequency of genotypes and RVD FOK-1 alleles was as follows: CC genotype (42%), CT (42%), and TT (16%). The number of alleles C was recorded at 63%, while the T allele was 37%. The average vitamin D levels in research subjects were 28.16 ng/ml with a standard deviation of 8.69 ng/ml. Based on the category, the frequency of research subjects showed 14% vitamin D deficiency, 38% insufficiency, and 48% sufficiency. On the other hand, the average cell proliferation index (KI-67) was recorded at 21.7% with grade distribution: +/- (18%), grade 1+ (50%), grade 2+ (30%), and Grade 3+ (2%).

Analysis of Results

Further analysis showed that there was no significant relationship between the three variables studied, namely: (1) FOK-1 polymorphism with a level of 25 (OH) D (p = 0.139); (2) levels of 25 (OH) D with the KI-67 proliferation index (p = 0.082); and (3) FOK-1 polymorphism with the KI-67 proliferation index (p = 0.285).

Conclusion

Based on the results of this study, it can be concluded that there is no significant relationship between polymorphisms of vitamin D fok-1 receptor genes (RS2228570) and plasma vitamin D levels of cell proliferation (KI-67) in breast cancer patients. This study provides an important insight into genetic and biochemical factors that play a role in the development of breast cancer, although the relationship between the polymorphism of the gene with vitamin D levels and cell proliferation is not proven significant in the sample under study. Further research with larger samples and diverse methods is needed to deepen our understanding of the role of vitamin D receptors in breast cancer.

Implications of the Study

This study has several implications for the understanding of breast cancer and the role of vitamin D in its development. Firstly, it highlights the importance of genetic and biochemical factors in the development of breast cancer. Secondly, it suggests that the relationship between vitamin D levels and breast cancer risk is complex and may be influenced by multiple factors. Finally, it emphasizes the need for further research into the role of vitamin D receptors in breast cancer.

Future Directions

Further research is needed to fully understand the relationship between polymorphisms of vitamin D fok-1 receptor genes (RS2228570) and plasma vitamin D levels of cell proliferation (KI-67) in breast cancer patients. This may involve larger sample sizes, diverse methods, and the use of advanced statistical techniques to analyze the data. Additionally, further research is needed to explore the mechanisms by which vitamin D receptors influence the growth and progression of breast cancer cells.

Limitations of the Study

This study has several limitations that should be acknowledged. Firstly, the sample size was relatively small, which may have limited the power of the study to detect significant relationships between the variables studied. Secondly, the study was limited to a specific population of breast cancer patients, which may not be representative of the broader population of breast cancer patients. Finally, the study relied on a single measure of vitamin D levels, which may not be a comprehensive measure of vitamin D status.

Conclusion

In conclusion, this study provides an important insight into the relationship between polymorphisms of vitamin D fok-1 receptor genes (RS2228570) and plasma vitamin D levels of cell proliferation (KI-67) in breast cancer patients. While the study found no significant relationship between these variables, it highlights the importance of genetic and biochemical factors in the development of breast cancer. Further research is needed to fully understand the role of vitamin D receptors in breast cancer and to explore the mechanisms by which vitamin D influences the growth and progression of breast cancer cells.
