Abstract
To determine the effect of a recombinant lentivirus containing human stem cell leukemia (SCL) gene on the expression of c-kit protein in damaged interstitial cells of Cajal (ICC) under high glucose condition.
 Methods: After isolation of ICC, the cells were cultured for 24 hours until the cells were adherent. After identification by inverted microscope and immunofluorescence, ICC cells were divided into two groups: A control group and a high glucose group. The control group was added with a medium containing 5 mmol/L of glucose. The high glucose group was added with a medium containing 20 mmol/L of glucose. After 48 h of continuous cultivation, the high glucose group was divided into 3 subgroups: A blank group, an empty lentivirus group, and an experimental group. The blank group, the empty lentivirus group, and the experimental group were added a medium containing PBS solution, empty lentivirus, and a recombinant lentivirus containing the SCL gene with a glucose concentration of 5 mmol/L, respectively. The cultures were incubated for 24 and 48 h. The expression of c-kit protein in ICC in each group was detected by Western blot.
 Results: After 24 or 48 h, the expression of c-kit protein in ICC was significantly lower in the blank group and the lentivirus group than that in the control group, and the expression of c-kit protein in ICC was significantly higher in the experimental group than that in the blank group and the empty lentivirus group, but it was still lower than that in the control group (all P<0.05).
 Conclusion: The recombinant lentivirus of SCL gene can up-regulate the expression of c-kit protein in functionally impaired ICC under high glucose condition.
