Abstract
Ischemia-reperfusion-induced cardiomyocyte mortality constitutes a prominent contributor to global morbidity and mortality. However, early diagnosis and preventive treatment of cardiac I/R injury remains a challenge. Given the close relationship between ferroptosis and I/R injury, monitoring their pathological processes holds promise for advancing early diagnosis and treatment of the disease. Herein, we report a near-infrared (NIR) light-activated dual-responsive nanoprobe (UCNP@mSiO2@SP-NP-NAP) for controllable detection of hydrogen polysulfide (H2Sn) and sulfur dioxide (SO2) during ferroptosis-related myocardial I/R injury. The nanoprobe's responsive sites could be activated by NIR and Vis light modulation, reversibly alternating for at least 5 cycles. We employed the nanoprobe to monitor the fluctuation levels of H2Sn and SO2 in H9C2 cardiomyocytes and mice, revealing that H2Sn and SO2 levels were up-regulated during I/R. The NIR light-activated dual-responsive nanoprobe could be a powerful tool for myocardial I/R injury diagnosis. Moreover, we also found that inhibiting the initiation of the ferroptosis process contributed to attenuating cardiac I/R injury, which indicated great potential for treating I/R injury.

Carbon Monoxide Releasing Molecule-3 Alleviates Oxidative Stress and Apoptosis in Selenite-Induced Cataract in Rats via Activating Nrf2/HO-1 Pathway. Curr Eye Res 2023; 48:919-929. [PMID: 37395371 DOI: 10.1080/02713683.2023.2232569] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Accepted: 06/29/2023] [Indexed: 07/04/2023]
Abstract
PURPOSE This study investigated the protective effect of carbon monoxide releasing molecule-3 (CORM-3), the classical donor of carbon monoxide, on selenite-induced cataract in rats and explore its possible mechanism. METHODS Sprague-Dawley rat pups treated with sodium selenite (Na2SeO3) were chosen as the cataract model. Fifty rat pups were randomly divided into 5 groups: Control group, Na2SeO3 (3.46 mg/kg) group, low-dose CORM-3 (8 mg/kg/d) + Na2SeO3 group, high-dose CORM-3 (16 mg/kg/d) + Na2SeO3 group, and inactivated CORM-3 (iCORM-3) (8 mg/kg/d) + Na2SeO3 group. The protective effect of CORM-3 was tested by lens opacity scores, hematoxylin and eosin staining, TdT-mediated dUTP nick-end labeling assay, and enzyme-linked immunosorbent assay. Besides, quantitative real-time PCR and western blotting were used for mechanism validation. RESULTS Na2SeO3 induced nuclear cataract rapidly and stably, and the achievement ratio of Na2SeO3 group was 100%. CORM-3 alleviated lens opacity of selenite-induced cataract and attenuated the morphological changes of the rat lens. The levels of antioxidant enzymes GSH and SOD in rat lens were also increased by CORM-3 treatment. CORM-3 significantly reduced the ratio of apoptotic lens epithelial cells, besides, CORM-3 decreased the expression of Cleaved Caspase-3 and Bax induced by selenite and increased the expression of Bcl-2 in rat lens inhibited by selenite. Moreover, Nrf-2 and HO-1 were upregulated and Keap1 was downregulated after CORM-3 treatment. While iCORM-3 did not exert the same effect as CORM-3. CONCLUSIONS Exogenous CO released from CORM-3 alleviates oxidative stress and apoptosis in selenite-induced rat cataract via activating Nrf2/HO-1 pathway. CORM-3 may serve as a promising preventive and therapeutic strategy for cataract.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Capsella bursa-pastoris (L.) Medic. (CBP) is a cruciferous plant valuable in reducing fever, improving eyesight and calming the liver. This herb was recorded in the Compendium of Materia Medica for cataract treatment. AIM OF THE STUDY To determine the effects and mechanism of CBP on cataract prevention and treatment using a selenite cataract model. MATERIALS AND METHODS The main compounds in CBP extract were analyzed by UPLC, 1H-NMR and 13C-NMR spectroscopic techniques. Flavonoids formed a significant proportion of its compounds, thus necessitating an evaluation of their inhibitory effects on the development of cataract using a selenite cataract model. The protective effects of CBP flavonoids (CBPF) against oxidative damage and the modulation of mitochondrial apoptotic pathway were subsequently verified on H2O2-treated SRA01/04 lens epithelial cells. RESULTS CBPF significantly alleviated the development of cataract by decreasing the MDA level and increasing the GSH-Px and SOD levels in the lens. It also inhibited H2O2-induced apoptosis in SRA01/04 cells, increased the expression of Bcl-2 protein and decreased the expressions of Caspase-3 and Bax proteins. CONCLUSION CBPF exerts a significant preventive effect on cataract development by regulating the mitochondrial apoptotic pathway of the lens epithelial cells. It is thus a potent traditional Chinese medicine (TCM) whose application should be further developed for the clinical treatment of cataract.

Abstract
Selenite cataracts are effective and convenient animal models for simulation of human senile nuclear cataracts. These models are widely used to study the effects of various stresses on eye lenses and to screen anticataract drugs. However, there have been no comprehensive toxicological evaluations of these animal models. To investigate the effects of sodium selenite on some important organs in selenite cataract model animals, this study analyzed (1) histopathology by hematoxylin and eosin (H&E) staining; (2) methionine sulfoxide reductase (Msr) A and B1 protein expression; (3) glutathione peroxidase (GPx), thioredoxin reductase (TrxR) and superoxide dismutase (SOD) activity; and (4) malondialdehyde (MDA) levels in the liver, kidney, and brain in a selenite cataract rat model. The results showed that sodium selenite induced severe oxidative damage, especially in the hippocampus and corpus striatum of the brain, in Sprague-Dawley (SD) rats. This damage was evidenced by mild gliocyte proliferation, significant disorder of neuronal arrangement with acidophilic changes in the hippocampus, and significant occurrence of focal microglia or lymphocytic infiltration in the corpus striatum after selenite injection for cataract simulation. The damage was closely related to significant decreases in antioxidant enzyme expression and activity and significant increases in lipid peroxidation (MDA) levels. Furthermore, nonsignificant swelling and scattered spotty necrosis were observed in the liver. These results imply that physiological changes in model animals should be considered when carrying out anticataract drug screening and that pathological changes in other nontarget organs should be prevented.

Abstract
Purpose: Cataracts are the leading cause of vision loss worldwide, and the over-production of reactive oxygen species (ROS) is the foremost underlying cause of cataracts. Reducing ROS levels can efficiently prevent lens opacification, as evidenced by many studies. Here, we inhibited ROS overproduction with trimetazidine (TMZ), which is an antioxidant, to explore the therapeutic effects of TMZ and the mechanism of lens opacification.Materials and methods: Sodium selenite-induced cataract formation resulted in a significant loss of lens transparency. This effect could be efficiently rescued by TMZ, which was further found to be an inhibitor of ROS production, as determined by assaying oxidative stress-related parameters (SOD activity, MDA, ·OH and H2O2 levels) during cataract formation. The experimental protocols involving animal research were approved by the Animal Care and Ethics Committee of Wenzhou Medical University and conducted according to the Association for Research in Vision and Ophthalmology under the guidelines of the Animal Welfare Act (SYXK 2015-0009).Results: Our study found that TMZ can retard the onset and progression of lens opacification in vivo in experiments using Sprague-Dawley (SD) suckling rats and can rescue the morphology of HLEB3 cells in vitro. The flow cytometry and DNA fragmentation assays showed that TMZ could prevent sodium selenite-induced apoptosis. The western blot analysing showed that the levels of apoptosis-associated Bcl-2 and Nrf2 were dramatically decreased following the sodium selenite treatment. In addition, the bisulfate DNA sequencing revealed that the demethylation of CpGs in the promoter region of Keap1 was stimulated, and that this demethylation could be inhibited by TMZ by rescuing the Nrf2 expression level.Conclusions: Our findings indicate that the antioxidant TMZ strongly reduces ROS production, which ultimately delays the progression of cataract formation, suggesting that treatment with TMZ represents a novel, promising antioxidant protection to retard cataract formation.
