Structured PICO

Does caveolin-1 knockdown alter insulin response and GLUT4/insulin receptor stability in 3T3-L1 adipocytes?

Population

Multiclonal mouse 3T3-L1 cell lines (adipocytes)

Intervention

Caveolin-1 knockdown (95% reduction) using small interfering RNA via lentiviral vectors

Comparator

Control cell lines infected with lentiviral vectors encoding scrambled RNAs

Outcome

Glucose transporter 4 (GLUT4) and insulin receptor protein levels and degradationsurrogate

Caveolin-1 loss of function in adipocytes reduces maximal insulin response by decreasing the stability and expression of insulin receptors and GLUT4.
