Обзор

In this study, investigators wanted to determine the effect of T2DM susceptibility gene mutations on self-expression. Participants (T2DM patients and controls) were recruited to identify genotypes and detect the levels of T2DM susceptibility genes expression in the fresh peripheral plasma. The normal pancreatic tissues or adjacent tissues of pancreatic cancer were also collected to identify the expression differences of T2DM susceptibility genes under different genotypes.

Подробное описание

The primary objective of this study was to investigate the changes of the expression of T2DM susceptible genes (NOS1AP, KCNQ1, TCF7L2, WSF1, GLP-1R, etc.) in participants (newly diagnosed T2DM patients and controls) after gene mutation.

Secondly, the expression differences of T2DM susceptible genes in T2DM patients with different genotypes were compared, and the relationship between the expression differences and clinicopathological characteristics of T2DM patients was analyzed.

Participants (newly diagnosed T2DM patients and healthy subjects) were screened from the department of endocrinology and health management center, whose fresh peripheral blood were collected. The normal pancreatic tissues or adjacent tissues of pancreatic cancer were collected in the department of general surgery. The DNA genome was extracted for genotyping, and then the expression levels of T2DM related susceptibility genes under different genotypes were detected by ELISA kits, PCR, WB,HE staining, IHC staining, ect.

The basic information of T2DM patients was collected, including demographic characteristics, physiological and biochemical data.Then investigators further compared the differences in the expression of susceptible genes between newly diagnosed T2DM patients and controls.

Вмешательства

Препарат Fresh normal pancreatic tissues or adjacent tissues of pancreatic cancer were collected from controls and T2DM patients without hypoglycemic drugs
Compared with newly diagnosed T2DM patients, healthy subjects in the control group had normal levels of blood glucose, lipids, glycated hemoglobin levels, etc. Fresh normal pancreatic tissues or adjacent tissues of pancreatic cancer were collected before taking antidiabetic drugs in both groups.
Препарат Fresh blood samples were collected from healthy subjects and T2DM patients without hypoglycemic drugs
The newly diagnosed T2DM group should not have taken antidiabetic drugs and meet the diagnosis of T2DM. Fresh blood samples were collected before medication for detection. In the control group (healthy subjects), the indicators of physical examination were within the normal range and no hypoglycemic drugs were taken. Similarly, fresh blood samples should be taken for testing.
