Dincer B, Cinar I, Erol HS, Demirci B, Terzi F. Gossypin mitigates oxidative damage by downregulating the molecular signaling pathway in oleic acid-induced acute lung injury. J Mol Recognit 2023; 36:e3058. [PMID: 37696682 DOI: 10.1002/jmr.3058] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 07/16/2023] [Accepted: 08/29/2023] [Indexed: 09/13/2023]
Abstract
One of the leading causes of acute lung injury, which is linked to a high death rate, is pulmonary fat embolism. Increases in proinflammatory cytokines and the production of free radicals are related to the pathophysiology of acute lung injury. Antioxidants that scavenge free radicals play a protective role against acute lung injury. Gossypin has been proven to have antioxidant, antimicrobial, and anti-inflammatory properties. In this study, we compared the role of Gossypin with the therapeutically used drug Dexamethasone in the acute lung injury model caused by oleic acid in rats. Thirty rats were divided into five groups; Sham, Oleic acid model, Oleic acid+Dexamethasone (0.1 mg/kg), Oleic acid+Gossypin (10 and 20 mg/kg). Two hours after pretreatment with Dexamethasone or Gossypin, the acute lung injury model was created by injecting 1 g/kg oleic acid into the femoral vein. Three hours following the oleic acid injection, rats were decapitated. Lung tissues were extracted for histological, immunohistochemical, biochemical, PCR, and SEM imaging assessment. The oleic acid injection caused an increase in lipid peroxidation and catalase activity, pathological changes in lung tissue, decreased superoxide dismutase activity, and glutathione level, and increased TNF-α, IL-1β, IL-6, and IL-8 expression. However, these changes were attenuated after treatment with Gossypin and Dexamethasone. By reducing the expression of proinflammatory cytokines and attenuating oxidative stress, Gossypin pretreatment provides a new target that is equally effective as dexamethasone in the treatment of oleic acid-induced acute lung injury.

Abstract
The selective inhibition of kinases from the diabetic kinome is known to promote the regeneration of beta cells and provide an opportunity for the curative treatment of diabetes. The effect can be achieved by carefully tailoring the selectivity of inhibitor toward a particular kinase, especially DYRK1A, previously associated with Down syndrome and Alzheimer's disease. Recently DYRK1A inhibition has been shown to promote both insulin secretion and beta cells proliferation. Here, we show that commonly available flavones are effective inhibitors of DYRK1A. The observed biochemical activity of flavone compounds is confirmed by crystal structures solved at 2.06 Å and 2.32 Å resolution, deciphering the way inhibitors bind in the ATP-binding pocket of the kinase, which is driven by the arrangement of hydroxyl moieties. We also demonstrate antidiabetic properties of these biomolecules and prove that they could be further improved by therapy combined with TGF-β inhibitors. Our data will allow future structure-based optimization of the presented scaffolds toward potent, bioavailable and selective anti-diabetic drugs.

Abstract
Amaç: Bu çalışmanın amacı, gossypin'in farklı kanser hücre hatlarında ısı şok proteinleri (HSP) genlerinin ekspresyon seviyesi üzerindeki etkisini incelemektir.
Gereç ve Yöntem: Hücreler, standart kültür koşulları altında büyütüldü. Kanser hücreleri, farklı konsantrasyonlarda (5-100 µg/ml) gossypin ve pozitif kontrol olarak sisplatin (50 µM) ile muamele edildi. Gossypin'in hücre canlılığı ve etkili doz aralığı (5-100 µg/ml), 24, 48 ve 72. saatlerde MTT ile belirlendi. RNA izolasyonu ve cDNA sentezinden sonra, HSP60 ve HSP70 gen ekpresyon seviyesi RT-PCR ile analiz edildi. Gen ekspresyonu için 2-∆∆ct methodu kullanıldı.
Bulgular: MTT sonuçlarına göre kanser hücre hatlarında 25-50-100 µg/ml gossipin dozlarının HSP60 ve HSP70 gen ekspresyon seviyeleri üzerinde etkili olduğu bulundu. Gossypin, üç hücre hattında HSP60 ve HSP70'in ekspresyonunu doza bağımlı olarak etkilemiştir. Üç hücre hattında, 50 µg/ml ve 100 µg/ml gossipin dozları, HSP60 ve HSP70'in ekspresyonunu kontrol grubuna kıyasla önemli ölçüde azalttı.
Sonuç: Sonuçlarımız, farklı hücre dizilerinde çeşitli dozlarda gossypinin antikarsinojenik etkisini güçlü bir şekilde desteklemektedir. Fakat, daha fazla in vivo araştırma ve insan çalışmalarına ihtiyaç olduğuna inanıyoruz. Bulgularımız, gossypin'nin farklı kanser türlerinin önlenmesi ve/veya tedavisi için yeni stratejiler geliştirmek için daha ileri araştırmalar için uygun aday ajan olabileceğini düşündürmektedir.

Abstract
AIM Ovarian ischemia-reperfusion (I/R) injury is a serious gynecological condition that affects women of reproductive age and reduces ovarian reserve. Management of I/R injury with detorsion causes reperfusion damage, in which oxidative stress plays a central role. This study aimed to investigate whether the gossypin (GOS) with antioxidant properties, a flavonoid, has beneficial effects on the biochemical, molecular, and histopathological aspects of ovarian I/R injury. METHODS Thirty-three female Balb/c mice were randomly divided into five groups as follows: Healthy (Sham-operated control group), I/R (IR group), I/R + GOS 5 (I/R with GOS 5 mg/kg), I/R + GOS 10 (I/R with GOS 10 mg/kg), and I/R + GOS 20 (I/R with GOS 20 mg/kg). This was followed by 3 h of ischemia and subsequent reperfusion for 3 h after detorsion was exposed. GOS was injected 2 h before reperfusion. RESULTS IL-1β, IL-6, TNF-α, NF-κB, and CASP-3 mRNA expressions, SOD (superoxide dismutase) activity, GSH (glutathione), and MDA (malondialdehyde) levels, and histopathological changes were evaluated in ovarian tissue. Histological examination indicated that treatment of ovarian I/R injury with GOS led to the improvement of ovarian tissue, which was accompanied by an increase in SOD activity and GSH level and a decrease in MDA level, NF-κB, TNF-α, IL-1β, and IL-6 expressions. GOS was also corrected by reducing the elevated expression of CASP-3 as apoptosis-change marker. CONCLUSION These findings indicate that the treatment of GOS may be useful as a conservative approach to reverse I/R injury via amelioration of oxidative stress parameters and histopathological scores, attenuation of inflammation, and the suppression of apoptosis.

Abstract
OBJECTIVES Methotrexate (MTX) is a broadly used anticancer. Its major side effect is hepatotoxicity. Gossypin is a flavonoid has a hepatoprotective effect as well as antitumor property. The study aimed at inspecting the protective effect of gossypin against MTX hepatotoxicity. MATERIALS AND METHODS Twenty-four adult male rats arranged into four groups (six rats each): control, gossypin control, MTX, and MTX+ gossypin. Animals were orally administered gossypin at 10 mg kg-1 day-1 for 7 days. MTX was injected i.p. (20 mg/kg-1 once) on 5th day. Liver enzyme and oxidative stress markers were assessed. BAX, transforming growth factor-beta (TGF-β) gene expressions, and P-glycoprotein (P-gp) were assessed. The histopathological study as well as the immunohistochemical study for hepatic caspase 3 and nuclear factor kappa-B (NFκ-B) was done. RESULTS MTX produced a significant increase of liver enzymes and distortion of hepatic architecture alongside with increased the hepatic collagen content. MTX administration significantly increased the oxidative stress markers and upregulated the pro-apoptotic BAX and the pro-fibrogenic TGF-β. MTX increased caspase 3 and NFκ-B expression, while diminished the expression of P-gp. Gossypin pretreatment improved the previous parameters, restored the normal hepatic architecture, reduced the hepatic fibrosis, and regained nearly normal expressions for BAX, TGF-β, caspase 3, and NFκ-B. Gossypin caused more reduction in P-gp hepatic expression. CONCLUSIONS Gossypin may be a valuable adjuvant therapy that protects the liver against MTX toxicity through antioxidant, anti-inflammatory, antiapoptotic mechanisms, and mediated P-gp expression reduction.

Abstract
Hibiscus sabdariffa L. (Malvaceae) is one of the well-known traditionally used remedy worldwide. It exhibited numerous pharmacological properties including antioxidant, antidepressant, sedative, anti-inflammatory, antiproliferative, antimicrobial and neuroprotective activities. The aim of this study is to highlight the mechanisms underlying the neuroprotective effects of anthocyanin-enriched extracts of two Hibiscus varieties (white and red calyces) in the management of Alzheimer's disease (AD) in addition to their metabolic profiling. The anthocyanin contents were determined quantitatively using the pH-differential technique and qualitatively by LC/MS/MS. The extracts were tested in vitro for their antioxidant potential as well as acetylcholinesterase inhibition activity and both showed promising activities. The LC/MS/MS analysis allowed the tentative identification of 26 and 24 metabolites in red and white calyces, respectively, represented by anthocyanins, flavonoids, aliphatic and phenolic acids. In vivo, streptozotocin induced AD in mice model was established and Hibiscus extracts were tested at a dose of 200 mg kg-1 compared to celecoxib (30 mg/kg). Histopathology of cerebral cortex and hippocampus, immunohistochemistry for tau- protein and caspase-3 with behavioral tests and measurement of several biochemical parameters were done. Hibiscus prevented memory impairment, and this could be attributed to the amelioration of STZ-induced neuroinflammation and amyloidogenesis. Consequently, Hibiscus represents a promising safe agent that can be repurposed for AD through exerting anti-inflammatory, anti-acetylcholinesterase, antioxidant, and anti-amyloidogenic activities.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE In the traditional system of Indian medicine, the whole plant and roots of Achyranthes aspera L have been extensively used to treat neurological conditions such as epilepsy and stroke by the various ethnic communities of India. AIM OF THE STUDY The present study was aimed to evaluate the cerebroprotective potential of methanol extract of A. aspera aerial parts (MeAA). MATERIALS AND METHODS Initially the MeAA was evaluated for total phenolic content and subjected to detailed liquid chromatography-mass spectrometry analysis. Additionally, it was evaluated for in vitro antioxidant activity in ferric reducing antioxidant power, 2, 2-diphenyl-1-picrylhydrazyl and oxygen radical absorbance capacity assays. Furthermore, in RAW 264.7 cell lines the effect of MeAA was evaluated on lipopolysaccharide-induced generation of reactive oxygen species, nitrite and tumor necrosis factor-α. Finally, the MeAA (400 and 800 mg/kg) was evaluated against ischemia-reperfusion (I/R)-induced brain injury in rats. In brief, male Wistar rats were allocated in to five groups (G-I to G-V, n = 10). G-I and G-II assigned as sham control and I/R control, and received only vehicle (carboxy methyl cellulose 0.5% w/v, 10 ml/kg, p.o.). G-III received quercetin (20 mg/kg, p.o.) and assigned as reference standard. G-IV and G-V group animals received 400 and 800 mg/kg oral doses of MeAA, respectively. All the treatments were given orally for a period of seven days and the parameters such as functional (neurological, cognitive and motor), morphological (edema and infarct area), biochemical (superoxide dismutase, catalase, reduced glutathione, lipid peroxidation, cytokines), and histopathological evaluations of the brain tissue was performed. RESULTS The MeAA exhibited 72.48 mg gallic acid equivalents/g of total phenolic content and the LC-MS/MS analysis showed acteoside, apigenin, and pentagalloyl glucose as major ingredients in the MeAA. In in vitro antioxidant assays, the MeAA showed good antioxidant activity with IC50 of 126.50 μg/ml in DPPH assay; FRAP and ORAC values of 759.65 and 979.4 in FRAP and ORAC assays, respectively. Further, the MeAA significantly suppressed the generation of ROS, nitrite and TNF-α in LPS activated RAW 264.7 cell lines. Besides, sixty mins of global cerebral ischemia followed by 24 h of reperfusion produced considerable alterations in neurobehavioral functions in the I/R control group compared to sham control, with a significant reduction in catalase and superoxide dismutase enzyme activities. Moreover, there was a significant reduction in reduced glutathione levels with increased lipid peroxidation. Furthermore, the levels of pro-inflammatory cytokines (TNF-α, IL-6, and ICAM-I) increased significantly and those of anti-inflammatory (IL-10) decreased. I/R insult increased the brain volume and aggravated cerebral infarct formation. Histopathological examination of the brain tissue revealed vascular congestion, cerebral edema, leukocyte infiltration, and brain tissue necrosis. Interestingly, seven days pretreatment with MeAA (800 mg/kg, p.o.) has offered significant protection against I/R-induced functional, morphological, biochemical and histopathological alterations in Wistar rats. CONCLUSIONS These findings suggest that the MeAA possesses potent cerebroprotective action through its antioxidant and anti-inflammatory mechanisms.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Colebrookea oppositifolia Smith is one of the extensively used plants to treat neurological conditions such as epilepsy by the various ethnic communities in sub-Himalayan regions of India such as Bhoxa, Tharu and nomadic Gujjars. AIM OF THE STUDY This study was conducted to evaluate the cerebroprotective effect of C. oppositifolia methanolic root (MeCO) extract in Wistar rats. MATERIALS AND METHODS The MeCO was characterized for total phenolic content and later subjected for detailed liquid chromatography-mass spectrometry analysis. Further, it was evaluated for in vitro antioxidant activity using 2, 2-diphenyl-1-picrylhydrazyl, ferric reducing antioxidant power and oxygen radical absorbance capacity assays. In addition, the MeCO was investigated on generation of ROS, nitrite, and TNF-α in LPS-stimulated RAW 264.7 cell lines. Finally, the cerebroprotective effect of MeCO was examined against global ischemia and reperfusion (I/R)-induced brain injury in Wistar rats. Male Wistar rats were allocated in to five groups (G-I to G-V, n = 10). G-I and G-II served as sham control and I/R control, respectively, and received only vehicle (0.5% w/v carboxy methyl cellulose, 10 ml/kg, p.o.). G-III served as reference standard and received quercetin (20 mg/kg, p.o.). G-IV and G-V animals received 200 and 400 mg/kg oral doses of MeCO, respectively. All the treatments were given for a period of seven days and the parameters such as neurobehavioral (neurological, and cognitive), and motor functions, biochemical (enzymatic and non-enzymatic antioxidants, TNF-α, IL-6, IL-10, ICAM-I), morphological (cerebral edema and infarct area) and histopathological evaluations were performed. RESULTS The MeCO showed a total phenolic content of 137.28 mg gallic acid equivalents/g, and LC-MS/MS analysis of MeCO showed presence of acteoside, gossypin, quercetin and ferulic acid as major ingredients (6680.3, 1.55, 3.52 and 431.1 ng/mg). In in vitro antioxidant assays, the MeCO exhibited potent activity with IC50 of 49.10 µg/ml in DPPH assay; FRAP and ORAC values of 1180.5 and 2983.5 respectively. Furthermore, the MeCO significantly inhibited generation of ROS, nitrite and TNF-α in LPS-stimulated RAW 264.7 cell lines. Sixty min of global ischemia with 24 h reperfusion produced substantial alterations in neurobehavioral functions in the I/R control group compared to sham control. In addition, a significant reduction in catalase and superoxide dismutase activities was observed. Moreover, lipid peroxidation increased and reduced glutathione levels decreased significantly. Furthermore, the levels of pro-inflammatory cytokines (TNF-α, IL-6, and ICAM-I) increased significantly and those of anti-inflammatory (IL-10) decreased. I/R insult increased the brain volume and aggravated cerebral infarct formation. Histopathological examination of the rat brain revealed vascular congestion, cerebral edema, leukocyte infiltration, and brain tissue necrosis. Interestingly, seven days pretreatment with MeCO (200 and 400 mg/kg) alleviated all the I/R-induced perturbances (neurobehavioral, and motor functions, biochemical, morphological and histopathological) compared with the I/R control. CONCLUSIONS The MeCO exhibit potent cerebroprotective activity through its potent antioxidant and anti-inflammatory mechanisms, and hence may be useful in the management of ischemic stroke and associated complications.

Abstract
BACKGROUND Prosopis chilensis is used locally in Sudan for inflammatory conditions of joints; however, literature lacks scientific evidence for anti-inflammatory effect of this plant. AIMS To evaluate anti-inflammatory and analgesic effects of prosopis chilenses. MATERIAL AND METHODS Edema inhibition percent (EI %) and hot plate method were used to evaluate anti-inflammatory and analgesic effects of Prosopis chilenses in Wistar albino rats. Anti-inflammatory and analgesic effects of Prosopis chilenses were compared to indomethacin and acetylsalicylic acid respectively. RESULTS Ethanolic extract of prosopis chilensis at a dose of 200 and 100mg/kg body weight achieved peak EI% (EI% = 96.1%) and (EI% = 94.4%) three and four hours after oral dosing respectively. The maximum EI% for indomethacin was 97.0% and was recorded after 4 hours following oral administration of the drug at a dose of 5 mg/kg body weight. Prosopis chilensis extracts at doses of 100 and 200 mg/kg body weight significantly increased the rats' response time to hot plate compared to acetylsalicylic acid at a dose rate of 100mg/kg body weight (P<0.05). CONCLUSION The current results suggest potential anti-inflammatory and analgesic effects of prosopis chilenses. Relevance of these effects to prosopis chilenses phy-to-constituents was discussed.
