Hyperoside, an active flavonoid glycoside isolated from many traditional Chinese medicines, has received much attention because of its potential role in osteoporosis treatment. In the present study, we investigated the antiosteoporotic role and mechanism of hyperoside on ovariectomized (OVX) mice. Sixty female Kunming mice received one of three treatments orally for 12 weeks: estradiol valerate (0.3 mg/kg body weight/day), hyperoside (20, 40, or 80 mg/kg body weight/day), or vehicle. We found that hyperoside was effective in preventing osteoporosis by increasing bone mineral density, restoring trabecular bone micro-architecture, and enhancing bone strength. Meanwhile, the activities of bone resorption markers, including tartrate-resistant acid phosphatase 5b (TRAP-5b) and C-terminal telopeptide of type I collagen (CTX), were significantly decreased, while the bioactivity of bone formation markers, osteocalcin (OC) and bone-specific alkaline phosphatase (BALP), were significantly increased. Mechanistically, hyperoside reduced the expression of receptor activator of nuclear factor-κB ligand (RANKL), TNF-receptor-associated factor 6 (TRAF6), phosphorylated inhibitor of nuclear factor-κB α (IκBα), NF-kB p65, and nuclear factor of activated T cell cytoplasmic 1 (NFATc1) and promoted the expression of osteoprotegerin (OPG). Therefore, the function of hyperoside might be related to the inhibition of the TRAF-6 mediated RANKL/RANK/NF-κB signaling pathway and the elevation of the OPG/RANKL ratio. These data demonstrated that hyperoside has potential applications as a drug for osteoporosis treatment.

Pseudomonas aeruginosa (P. aeruginosa) is a common pathogen in hospital-acquired infection and is readily able to form biofilms. Due to its high antibiotic resistance, traditional antibacterial treatments exert a limited effect on P. aeruginosa biofilm infections. It has been indicated that hyperoside inhibits P. aeruginosa PAO1 (PAO1) biofilm formation without affecting growth. Therefore, the current study examined the biofilm formation and quorum sensing (QS) system of PAO1 in the presence of hyperoside. Confocal laser scanning microscopy analysis demonstrated that hyperoside significantly inhibited biofilm formation. It was also observed that hyperoside inhibited twitching motility in addition to adhesion. Data from reverse transcription-quantitative polymerase chain reaction indicated that hyperoside inhibited the expression of lasR, lasI, rhlR and rhlI genes. These results suggest that the QS-inhibiting effect of hyperoside may lead to a reduction in biofilm formation. However, the precise mechanism of hyperoside on P. aeruginosa pathogenicity remains unclear and requires elucidation in additional studies.

Heart failure (HF) is an end-stage of various serious cardiovascular diseases, which causes liver injury. Hyperoside has been reported to exert protective effect on liver injury and fibrosis. However, the role and related mechanisms of hyperoside in HF-induced liver fibrosis are still unclear. In the current study, we established a model of HF via aortocaval fistula (ACF) in rats in vivo. Hyperoside treatment in ACF rats increased cardiac output, the maximum peak rate of rise/fall in left ventricular pressure (+dP/dt, -dP/dt) and LV ejection fraction (LVEF), decreased LV end-systolic pressure (LVESP), LV end-diastolic pressure (LVEDP) and LV end-systolic volume (LVESV), and reduced heart weight/body weight ratio in a dose-dependent manner. Moreover, hyperoside could attenuate liver fibrosis and injury in ACF rats, as evidenced by reduction of fibrosis area and hydroxyproline content, amelioration of edema and degeneration of liver cell vacuoles, and inhibition of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) levels. Further, α-smooth-muscle actin (α-SMA), collagen I, profibrotic factor-connective tissue growth factor (CTGF), matrix metalloproteinase-2 (MMP2) and MMP9 levels were down-regulated in hyperoside-treated ACF rats. Additionally, hyperoside inhibited the activation of TGF-β1/Smad pathway. Finally, we confirmed that hyperoside suppressed TGF-β1-mediated hepatic stellate cell activation in vitro. Collectively, hyperoside showed a suppressive role in HF-induced liver fibrosis and injury.
