In detail, CDK5 tv1 levels correlated positively with serum insulin (μU/ml) and glycated haemoglobin (HbA1c; % or mmol/mol) levels and negatively with hyperlipidemia in T2D patients, while positively with serum triglycerides levels (mg/dl) (p < 0.05) in CTRF+ subjects. Here, CDK5 is linked to hyperlipidemia.
