Diabetes mellitus (DM) is considered a persistent metabolic disorder in humans
and animals that impacts more than 170 million people around the world. DM is
associated with nephrotoxicity through ROS overproduction. Robustaflavone (RF)
is a bioactive biflavonoid sourced from
Nandina domestica. This work was carried out to investigate the therapeutic
potential of RF against DM-provoked renal injury in rats. Albino rats were
portioned into 4 treatment-groups each having 12 rats as follows: Control, DM
(65mg/kg), DM + RF (65mg/kg+150mg/kg), and RF (150mg/kg). Current study outcomes
displayed that DM-induction increased the levels of glucose, HbA1c,
inflammatory, pro-apoptotic, renal injury and oxidative stress markers, while
lowering the activities of antioxidants as well as insulin and anti-apoptotic
marker levels. Moreover, DM induction instigated numerous severe histological
anomalies in renal tissues. However, RF lowered the glucose and HbA1c levels
while upregulating the insulin concentration. RF administration enhanced the
enzymatic activities of antioxidants, including glutathione peroxidase (GPx),
superoxidase dismutase (SOD), glutathione S-transferase (GST), glutathione
(GSH), catalase (CAT), and glutathione reductase (GSR) but malonaldehyde (MDA)
level and reactive oxygen species (ROS) were lowered. RF administration also
lowered the concentration of creatinine, urea, NGAL, urinary proteins, kidney
injury molecule-1 (KIM-1), and urobilinogen. Simultaneously, there was an
increase in creatinine clearance concentration. Moreover, RF supplementation
lowered inflammatory cytokines levels [nuclear factor-kappa B (NF-κB),
Interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), cyclooxygenase-2
(COX-2), and interleukin one beta (IL-1β)]. RF administration also lowered
pro-apoptotic markers (Bax & Caspase-3) levels, while increasing anti-apoptotic
marker (Bcl-2) levels and enhancing histological architecture of renal tissues.
These outcomes demonstrate that RF confers significant protection against
DM-induced renal injury via targeting oxidative stress, inflammatory and
apoptotic pathway.
