Résumé
Diabetes is one of the global health threat. Type 2 Diabetes mellitus (T2DM) is associated with life-threatening complications. This work, aimed to study the association between T2DM and IGFBP-1 gene methylation, gene polymorphism and serum levels of IGFBP-1. We included 100 subjects with T2DM and 100 control. DNA methylation of IGFBP-1 was analyzed using pyrosequencing, IGFBP-1 gene polymorphism was analyzed using real time polymerase chain reaction and serum level of IGFBP-1 was measured by ELISA. There was DNA hyper methylation levels of IGFBP1 gene at each of the six CpG sites in T2DM patients than control (P < 0.001). IGFBP-1 gene polymorphism (rs 2854843) CC pattern was significantly associated with DM, P = 0.002. Also, there was decrease in serum IGFBP-1 in patients with T2DM than control group (P < 0.001). We concluded that DNA hyper methylation of IGFBP-1 gene and CC polymorphism (rs 2854843) of IGFBP-1 gene are associated with T2DM in Egyptian patients, also, decrease serum level of IGFBP-1. Further cohort study is recommended with large sample size to detect which one, epigenetic changes or polymorphism of IGFBP-1 gene, is the cause of T2DM or even both.

BACKGROUND
BACKGROUND
Diabetes is one of the global health threat. Type 2 Diabetes mellitus (T2DM) is associated with life-threatening complications. This work, aimed to study the association between T2DM and IGFBP-1 gene methylation, gene polymorphism and serum levels of IGFBP-1.
METHOD
METHODS
We included 100 subjects with T2DM and 100 control. DNA methylation of IGFBP-1 was analyzed using pyrosequencing, IGFBP-1 gene polymorphism was analyzed using real time polymerase chain reaction and serum level of IGFBP-1 was measured by ELISA.
RESULTS
RESULTS
There was DNA hyper methylation levels of IGFBP1 gene at each of the six CpG sites in T2DM patients than control (P < 0.001). IGFBP-1 gene polymorphism (rs 2854843) CC pattern was significantly associated with DM, P = 0.002. Also, there was decrease in serum IGFBP-1 in patients with T2DM than control group (P < 0.001).
CONCLUSION
CONCLUSIONS
We concluded that DNA hyper methylation of IGFBP-1 gene and CC polymorphism (rs 2854843) of IGFBP-1 gene are associated with T2DM in Egyptian patients, also, decrease serum level of IGFBP-1. Further cohort study is recommended with large sample size to detect which one, epigenetic changes or polymorphism of IGFBP-1 gene, is the cause of T2DM or even both.
