Type 2 diabetes

Patients who have not been treated with an SGLT2 inhibitor will be assigned to the dapagliflozin (Forxiga) treatment group, while patients who have not been treated with a GLP-1 receptor agonist will be assigned to the oral semaglutide (Rybelsus) treatment group. An observation period of 1 to 2 months will be set after obtaining consent. Patients with HbA1c levels below 7.0% or above 10.0% at the end of the observation period will be excluded. At the start of treatment, dapagliflozin will be administered at 5 mg/day, and oral semaglutide at 3 mg/day. In the oral semaglutide group, the dosage will be increased to 7 mg/day after one month of treatment. The treatment period will last for three months.

Type 2 diabetes

The difference in Sirt1 gene expression in peripheral blood at the start of treatment and three months after treatment in all cases.

1)The difference in the gene expression levels of p53, Mcp1, Nlrp3, Foxo3, and Il-1be-ta in peripheral blood leukocytes, as well as Sirt1 activity, at the start of treatment and three months after treatment in all cases.
2)The difference in the gene expression levels of Sirt1, p53, Mcp1, Nlrp3, Foxo3, and Il-1be-ta in leukocytes, as well as Sirt1 activity, at the start of treatment and three months after treatment in the dapagliflozin or oral semaglutide treatment groups.
3)The difference in the gene expression levels of Sirt1, p53, Mcp1, Nlrp3, Foxo3, and Il-1be-ta, as well as Sirt1 activity, at the start of treatment or three months after treatment in the dapagliflozin or oral semaglutide treatment groups.
