Abstract: Naringin, a flavanone glycoside, and naringenin, the aglycone of naringin, are commonly found in the pericarp of citrus fruits and have also been considered as potential bioactive flavanones. In the present study, treatment with naringenin showed an inhibitory effect on SIV formation in zebrafish embryos, which demonstrates its potential anti-angiogenic activity. In a chemically-induced blood vessel loss model in zebrafish, we found that naringin exhibited remarkably pro-angiogenesis activity on the restoration of blood vessel loss, and significantly reversed VRI-induced down-regulation of flt1 mRNA expression. In an in vitro study of cultured human umbilical vein endothelial cells (HUVEC), our results showed that naringin specifically promoted HUVEC migration but not proliferation. Taken together, these results suggest that naringin and naringenin have differential angiogenesis activities where naringin, as a novel angiogenic agent, has the potential to be developed as a therapeutic agent for diseases associated with insufficient angiogenesis, such as ischemia heart disease.

Abstract: Heart failure is a frequent unfavorable outcome of pathological cardiac hypertrophy. Recent increase in dietary fructose consumption mirrors the rise in prevalence of cardiovascular diseases such as cardiac hypertrophy leading to concerns raised by public health experts. Mitochondria, comprising 30% of cardiomyocyte volume, play a central role in modulating redox-dependent cellular processes such as metabolism and apoptosis. Furthermore, mitochondrial dysfunction is a key cause of pathogenesis of fructose-induced cardiac hypertrophy. Naringin, a major flavanone glycoside in citrus species, has displayed strong antioxidant potential in models of oxidative stress. In this study, we evaluated protective effects of naringin against fructose-induced cardiac hypertrophy and associated mechanisms of action, using in vitro and in vivo models. We found that naringin suppressed mitochondrial ROS production and mitochondrial dysfunction in cardiomyocytes exposed to fructose and consequently reduced cardiomyocyte hypertrophy by regulating AMPK-mTOR signaling axis. Furthermore, naringin counteracted fructose-induced cardiomyocyte apoptosis, and this function of naringin was linked to its ability to inhibit ROS-dependent ATM-mediated p53 signaling. This result was supported by observations in in vivo mouse model of cardiac hypertrophy. These findings indicate a novel role for naringin in protecting against fructose-induced cardiac hypertrophy and suggest unique therapeutic strategies for prevention of cardiovascular diseases.

Abstract: Acrolein (2-propenal) is ubiquitous in the environment and connections exist between acrolein exposure and lung cancer risk. Here we investigated the effects of naringin on acrolein induced-lung injuries in mice. Male C57BL/6 mice were allocated into four groups: Vehicle group (no acrolein), Naringin only group (80 mg of naringin/kg bw + no acrolein), Acrolein group (ACR group; acrolein), and Naringin + Acrolein group (NAG+ACR group; 80 mg of naringin/kg bw and acrolein). The mice were subjected acute acrolein inhalation (10 ppm for 12 h) in an inhalation chamber and naringin was intraperitoneally administered to the mice one hour before acrolein exposure. The results demonstrated that, in the NAG+ACR group, pulmonary injuries (e.g., airspace enlargement, lung inflammation) were all significantly improved compared to the ACR group. Further, key markers of MAPK signaling (e.g., p-p38, p-JNK), p53 signaling markers (e.g., p-Chk2, p53), NF-κB signaling axis (e.g., IL-1 β, TNF-α), and oxidative damage markers (e.g., GSSG:GSH ratio, oxidative DNA damage) were all effectively mitigated by the naringin treatment. Naringin provided protection against the environmental toxicant, acrolein, in mice lung via modulating MAPK, p53, and NF-κB signaling pathways and our data may provide significant implications considering the prevalence of acrolein.

Abstract: Hypertrophy is a very common pathologic phenomenon of scar hyperplasia after human skin injury and wound healing. In this article, we first proved that naringin could inhibit the proliferation of fibroblasts by MTT experiments. Flow cytometry indicated that naringin could block the cell cycle and promote apoptosis. Transwell experiments showed that naringin could inhibit the motility activity of fibroblasts. We also found that naringin specifically inhibits the kinase activity of Akt and the phosphorylation of Akt in hypertrophic scar fibroblasts by Kinase-Glo, western blot and real-time PCR assays. Subsequently, western blots and real-time PCR indicated that naringin can inhibit phosphorylation of Akt and downstream proteins of Akt. Our data demonstrated that naringin inhibits the development of hypertrophic scars, at least to a certain extent, by its inhibition of Aktp.
