Background: Metformin affects not only glucose, but also lipid metabolism. The uptake of metformin in the liver is mainly mediated by transporters OCT1and OCT2 (encoded by SLC22A1 gene), whereas MATE1 (encoded by SLC47A1 gene) is responsible for its elimination into the urine and bile. We investigated the interaction between SLC22A1 rs628031 and SLC47A1 rs2289669 variants with the lipid profile of type 2 diabetes (T2DM) patients consuming metformin.
Methods: Sociodemographic data, metformin consumption and laboratory data of 23 T2DM participants were obtained from medical records at Bhayangkara Hospital, Palembang. DNA from whole blood was extracted using the Chelex method. Polymerase chain reaction was carried out, followed by restriction fragment length polymorphism detection using restriction enzymes. Polymorphism was assessed by electrophoresis and visualization on agarose gel.
Results: There was no significant association between SLC22A1 rs628031 and SLC47A1 rs2289669 with the lipid profile of T2DM patients (p>0.05). However, there was an increased trend of total cholesterol and LDL levels in patients with rs628031 variants compared to wildtype.
Conclusion: Further study with large cohorts is needed to confirm the association between these two single nucleotide polymorphisms and lipid profile, as we showed a particular trend of lipid profile for those with rs628031 variants.
