CXCL1 and medical procedure: To further validate the insights gained from microarray datasets and diabetic mice kidneys, we integrated human diabetic kidney-related single nucleus RNA-sequencing (snRNA-seq) datasets, namely GSE195460, GSE151302, and GSE131882, in an effort to probe the dynamics of chemokines (specifically CXCL1, CXCL6 and CCL19) and immune cell infiltration.
