Glimepiride as insulin sensitizer: increased liver and muscle responses to insulin

Abstract: The increased GLUT4 protein expression and glucose utilization in oxidative muscle and the increased insulin sensitivity and glycogen storage in liver evidence the insulin-sensitizer effect of glimepiride, which must be important to enable the glimepiride drug to promote an efficient glycaemic control.

“…For subcellular fractionation, tissue samples were homogenized in sucrose buffer pH 7 . 4 (10 mmol/l Tris-HCl, 1 mmol/l EDTA and 250 mmol/l sucrose) and subjected to differential centrifugations to obtain PM, microsomalenriched (M), and total membrane (TM) fractions of adipose tissue (Machado et al 1994) and skeletal muscle (Mori et al 2008). Protein (40 mg) from each sample was subjected to electrophoresis and immunodetection as described (Zanquetta et al 2006).…”

“…As células β-pancreáticas são capazes de aumentar a secreção de insulina na tentativa de contrabalancear a resistência à insulina, resultando em um estado de hiperinsulinemia, comumente encontrado na obesidade (JEANRENAUD, 1978;PAPA et al, 1997). Entretanto, a presença da resistência insulínica em nossos ratos MSG somente foi confirmada pelo teste de tolerância à insulina (ITT), o que já havia sido relatado em estudo anterior de nosso laboratório (MORI et al, 2008). A presença de normoinsulinemia na vigência de resistência à insulina pode indicar um estado inicial de desenvolvimento da resistência, no qual o distúrbio glicêmico ainda não é suficiente para acionar hiperinsulinemia detectável.…”

“…A glimepirida, embora tenha alta afinidade pelas células beta, apresenta efeito antihiperglicemiante superior ao de outras sulfoniluréias, o que sugeriu um efeito de aumentar a sensibilidade à insulina (KRAMER et al, 1996;MORI et al, 2008;.…”
