Abstract
Our previous study examined the phytochemical composition and bio-activities of raw daylily flower (Hemerocallis fulva L.). However, this plant food is usually served via heat process such as cooking in a soup. This study aimed to investigate the phytochemical profile and biofunctions of steamed daylily flower (SDF). The content of total phenolic acids, total flavonoids, total carotenoids, total anthocyanins and total triterpenoids in SDF aqueous extract was assessed. Normal cardiac and hepatic cells, H9c2 and L-02 cells, were used to evaluate the protective effects of SDF against ethanol. SDF concentrations of 0.25%, 0.5%, and 1% were applied to treat H9c2 or L-02 cells for 48 h at 37 °C initially, followed by exposure to ethanol at 150 mM for 24 h at 37 °C. Results showed that the content of assessed phytochemicals was in the range of 1019-2045 mg/100 g dry weight. Flavonoids and triterpenoids were two major detected phytochemicals in SDF. SDF treatments at 0.5% and 1% increased the viability of H9c2 cells, but at three concentrations enhanced the survival of L-02 cells. SDF at 0.5% and 1% up-regulated Bcl-2 messenger RNA (mRNA) expression and down-regulated Bax mRNA expression. Ethanol increased reactive oxygen species production, decreased glutathione content, as well as lowered glutathione peroxidase and catalase activities. SDF treatments reversed these changes. SDF at 0.5% and 1% reduced the activity of cytochrome P450 2E1 and nicotinamide adenine dinucleotide phosphate oxidase, limited p47phox mRNA expression, as well as enhanced factor E2-related factor 2 and heme oxygenase-1 mRNA expression. SDF at three concentrations decreased gp91phox mRNA expression. In conclusion, these novel findings indicated that SDF aqueous extract was rich in phytochemicals and provided anti-apoptotic and anti-oxidative actions to protect cardiac and hepatic cells against ethanol. Thus, SDF might be considered as a functional food with multiple bio-activities.

Abstract
This study aimed to determine the role of oxidative stress produced by the renin-angiotensin system (RAS) in cataract formation in streptozotocin-induced diabetic rats (STZ) using angiotensin II receptor blockers (ARBs). Rats were treated with streptozotocin and orally administered candesartan (2.5 mg/kg/day) or a normal diet for 10 weeks until sacrifice. Cataract progression was assessed through a slit-lamp examination. Animals were euthanized at 18 weeks, and the degree of cataract progression was evaluated. Oxidative stress was also assessed. In STZ-treated rats, lens opacity occurred at 12 weeks. Cataract progression was inhibited in the ARB-treated group compared with the placebo group (p < 0.05). STZ-treated rats exhibited upregulated angiotensin-converting enzyme (ACE) gene expression than control rats. Oxidative stress-related factors were upregulated in the placebo-treated group but suppressed in the ARB-treated group. A correlation coefficient test revealed a positive correlation between ACE gene expression and oxidative stress-related factors and a negative correlation between ACE and superoxide dismutase. Immunostaining revealed oxidative stress-related factors and advanced glycation end products in the lens cortex of the placebo-treated group. The mechanism of diabetic cataracts may be related to RAS, and the increase in focal ACE and angiotensin II in the lens promotes oxidative stress-related factor production.

Abstract
HLE-B3 cell line, a human lens epithelial cell line, was used to examine the anti-glycative and anti-oxidative protection of aqueous extract prepared from steamed red amaranth leaves against high glucose induced injury. Phytochemical profile of this aqueous extract was analyzed. HLE-B3 cells were pretreated by this aqueous extract at 0.25%, 0.5%, or 1%, and followed by high glucose treatment. Results showed that the content of phenolic acids, flavonoids, anthocyanins, carotenoids, and triterpenoids in this aqueous extract was in the range of 1,107-2,861 mg/100 g dry weight. High glucose decreased cells viability and suppressed Bcl-2 mRNA expression. This aqueous extract pretreatments raised 11-42% cell survival and upregulated 20-47% Bcl-2 mRNA expression. High glucose reduced Na+ -K+ ATPase activity and mitochondrial membrane potential (MMP). This aqueous extract raised 27-40% Na+ -K+ ATPase activity, and 18-51% MMP. High glucose stimulated the generation of total advanced glycative endproducts (AGEs), methylglyoxal, and reactive oxygen species (ROS). This aqueous extract pretreatments lowered total AGEs, methylglyoxal, and ROS levels in the range of 0.38-1.17 folds, 1.7-4.9 nmol/mg protein, and 0.35-1.06 relative fluorescence unit/mg protein. High glucose upregulated mRNA expression of aldose reductase, nuclear factor kappa B, and p38. This aqueous extract pretreatments decreased mRNA expression of these factors in the range of 75-159%, 57-151%, and 54-166%. High glucose downregulated mRNA expression of nuclear factor E2-related factor 2 (Nrf2). This aqueous extract pretreatments increased 12-38% Nrf2 mRNA expression. These results suggested that this aqueous extract might be a potent nutritional supplement to prevent diabetic retinopathy.

Abstract
Thioredoxin (Trx) is an important protein that controls oxidative damage in almost all eukaryotic cells. Trx interaction protein (Txnip) has been reported to negatively regulate the bioavailability of Trx and inhibit its biological function. The E3 ubiquitin ligase ITCH can specifically degrade Txnip via ubiquitination. The apoptosis of human lens epithelial cells (HLECs), which are highly sensitive to redox caused by oxidative stress, is a significant factor for the development of sugar cataract in a high-glucose environment. However, whether Trx, Txnip and ITCH contribute to the progression of sugar cataracts and the underlying mechanisms remain unknown, and thus, identifying these were the aims of the present study. The present results suggested that the expression levels of Trx, Txnip and ITCH in HLECs cultured with different glucose concentrations were detected by reverse transcription-quantitative PCR and western blotting, and the apoptotic rate of the cells was detected by flow cytometry and superoxide detection assay. The interaction between ITCH and Txnip was determined by co-localization immunofluorescence and co-immunoprecipitation. In addition, a vector and small interfering RNA of ITCH were transfected to overexpress and knockdown ITCH, respectively, to alter the expression of downstream proteins and cell apoptosis. It was found that Txnip was highly expressed in cultured HLECs in high-glucose environment, and the antioxidative function of Trx was restricted and suppressed, thus promoting apoptosis. The overexpression of ITCH increased the expression of Trx and decreased oxidative stress and apoptosis by decreasing Txnip in cultured HLECs, while downregulation of ITCH significantly decreased the expression of Trx and enhanced oxidative stress and apoptosis. Therefore, the present results indicated that ITCH could regulate the apoptosis of HLECs that were cultured in high-glucose concentration and that it may be a treatment target for sugar cataract.

Abstract
Cataract is the principal cause of blindness. The enzyme, aldose reductase (AR) is a key player in polyol pathway. Buildup of polyols and oxidative stress are the main causes of cataractogenesis. This study investigated the cytoprotective properties of esculetin and idebenone in galactose-induced cataract. Rats were partitioned into four groups each of ten rats. Control group was fed with normal diet; group 2 rats were fed with galactose diet (50%); groups 3, 4 rats were fed with galactose diet concurrently with either esculetin (50 mg/kg BW) or idebenone (100 mg/kg BW), for 20 days. The study revealed that esculetin and idebenone significantly reduced the elevated levels of Bax/Bcl-2 ratio, malondialdehyde, and DNA fragmentation and increased total antioxidant capacity level in lenses compared to the cataract-induced group. Only esculetin decreased AR, galactitol, and advanced glycated end products levels in lenses. Histopathological examinations supported the biochemical findings. Esculetin and idebenone may have chemopreventive effects for sugar cataract. PRACTICAL APPLICATIONS: Cataract is an age-related disease that might cause blindness in older adult people. Presently, no absolute pharmacological treatment is accessible for cataract. The use of natural products or their derivatives attract particular attention in modern medicines as they are believed to be safer with few or no side effects. Esculetin is a polyphenolic compound found in many medicinal plants. Idebenone is a synthetic analogue of coenzyme Q10. The current study is an approach to explore the anticataract effects of esculetin and idebenone in galactose-induced cataract in rats. Our study proved that both agents have anticataractogenic potentials due to their antioxidant and antiapoptotic properties.

Abstract
AIM To explore the effects of IκBα SUMOylation and NF-κB p65 deacetylation on NF-κB p65 activity induced by high glucose in cultured human lens epithelial cells (HLECs). METHODS HLECs (SRA01/04) were cultured with 5.5, 25, and 50 mmol/L glucose media for 24h, and with 50 mmol/L glucose media for 0, 12, and 24h respectively. SUMO1 and SIRT1 expressions were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot (WB). IκBα and NF-κB p65 expressions were detected by WB. With NAC, DTT, MG132 or Resveratrol (RSV) treatment, SUMO1 and SIRT1 expressions were detected by WB. Protein expression localizations were examined by immunofluorescence and co-immunofluorescence. The effects of SUMO1 or SIRT1 overexpression, as well as MG132 and RSV, on the nuclear expression and activity of IκBα and NF-κB p65 were analyzed by immunoblot and dual luciferase reporter gene assay. RESULTS SUMO1 and SIRT1 expressions were influenced by high glucose in mRNA and protein levels, which could be blocked by NAC or DTT. SUMO1 was down-regulated by using MG132, and SIRT1 was up-regulated under RSV treatment. IκBα nuclear expression was attenuated and NF-κB p65 was opposite under high glucose, while IκBα and NF-κB p65 location was transferred to the nucleus. SUMO1 or SIRT1 overexpression and MG132 or RSV treatment affected the nuclear expression and activity of IκBα and NF-κB p65 under high glucose condition. CONCLUSION IκBα SUMOylation and NF-κB p65 deacetylation affect NF-κB p65 activity in cultured HLECs under high glucose, and presumably play a significant role in controlling diabetic cataract.
