Exploring the pharmacological mechanism of fermented Eucommia ulmoides leaf extract in the treatment of cisplatin-induced kidney injury in mice: Integrated traditional pharmacology, metabolomics and network pharmacology

Cisplatin (CP) is a widely utilized anticancer drug, which also produces significant side effects, notably acute kidney injury (AKI). Fermented Eucommia ulmoides leaf (FEUL), a medicinal and edible Chinese herbal remedy, is known for its renoprotective properties. However, the effect and underlying mechanism of FEUL extract in AKI therapy have remained largely unexplored. This research aimed to elucidate the protective roles of FEUL extract in an AKI mouse model through biochemical assays, histopathological examinations, and investigating the underlying mechanisms based on metabolomics and network pharmacology. The findings demonstrated that pretreatment with orally administered FEUL extract significantly reduced blood urea nitrogen (BUN), and serum creatinine (SCr) levels, and ameliorated CP-induced kidney histopathological injuries. Moreover, FEUL extract attenuated CP-induced endoplasmic reticulum (ER) stress by reducing the protein expressions of PERK, IRE 1α, GRP78, ATF6, ATF4, and CHOP. The metabolomics results indicated that a total of 31 metabolites, involved in taurine and hypotaurine metabolism, lysine degradation, and steroid hormone biosynthesis, were altered after FEUL extract administration. Furthermore, metabolomics integrated with network pharmacology revealed that 8 targets, 4 metabolites, and 3 key pathways including steroid hormone biosynthesis, purine metabolism, and tryptophan metabolism were the main mechanisms of FEUL extract in treating CP-induced AKI. These findings suggested that FEUL extract could offer valuable insights for potential CP-induced AKI treatment strategies.

The Potential of Human Wharton's Jelly Mesenchymal Stem Cells Secretome Based Topical Gel for Therapeutic Application

Background

Diabetic Foot Ulcer (DFU) might be worsened by neuropathy and vascular issues. This condition can cause 14.3% fatality, stressing the need for effective wound healing therapy. Wound healing is a complex biological process, and human Wharton's Jelly Mesenchymal Stem Cells (hWJMSCs) may help manage DFU treatment issues. This research focuses on utilizing a gel carrier to deliver bioactive substances from Wharton's Jelly Mesenchymal Stem Cells secretome (hWJ-MSCs-Sec) as a possible treatment for DFU.

Methods

To maintain quality, hWJMSCs-Sec is thoroughly mixed with carbomer gel and freeze-dried. ELISA test is performed to determine the characterization of the gel of hWJMSCs-Sec such as Keratinocyte Growth Factor (KGF), Platelet-Derived Growth Factor (PDGF), Hepatocyte Growth Factor (HGF), Epidermal Growth Factor (EGF), and Heparin-Binding EGF-Like Growth Factor (HB-EGF). The antioxidant activity was also measured with Hydrogen peroxide (H2O2), Nitric oxide (NO), and Ferric Reducing Antioxidant Power (FRAP) assay. Proliferation assay was utilized using WST-8 and the wound healing potential was assessed via the migration cell ability of scratched-human skin fibroblast (BJ cells).

Results

The freeze-dried hWJ-MSCs-Sec showed higher levels of KGF, HGF, PDGF, EGF, HB-EGF, and the antioxidant activities compared to fresh hWJ-MSCs-Sec. Additionally, the gel of freeze-dried hWJ-MSCs-Sec exhibited higher levels compared to the gel of fresh hWJMSCs-Sec. This was evidenced by faster closure of scratched wounds on BJ cells treated with hWJMSCs-Sec and freeze-dried hWJ-MSCs-Sec gel.

Conclusion

The freeze-dried hWJ-MSCs-Sec gel exhibits superior quality compared to the non-freeze-dried hWJ-MSCs-Sec gel. This demonstrates that the freeze-drying procedure can maintain the bioactive chemicals found in hWJMSCs-Sec, potentially enhancing the efficacy of this gel in promoting cell regeneration for wound healing.

Brazilin cream from Caesalpinia sappan inhibit periodontal disease: in vivo study

Background

Gingivitis is an inflammation of the gums that is the initial cause of the development of periodontal disease by the activity of Nuclear Factor-kappa B (NF-κB), Interleukin-1β (IL-1β), Interleukin-6 (IL-6), p38, and Tumor Necrosis Factor-α (TNF-α). Unaddressed chronic inflammation can lead to persistent disturbances in other parts of the body. Brazilin is a naturally occurring plant chemical that may have antibacterial and anti-inflammatory effects. Treatment based on the natural plant compound, brazilin, is developed in the form of a topical cream for easy application.

Objective

The aim is to develop the natural compound brazilin in the form of a topical cream as an anti-inflammatory agent to reduce NF-κB expression through Imunohistochemistry (IHC) methods, and the expression of pro-inflammatory genes IL-1β, IL-6, p38, and TNF-α.

Methods

Male Sprague-Dawley rats were induced with gingivitis using P. gingivalis bacteria. The observed groups included rats treated with a single application of brazilin cream and rats treated with two applications of brazilin cream. The treatment was administered for 15 days. On days 3, 6, 9, 12, and 15, anatomical wound observations and wound histology using hematoxylin-eosin and Masson's Trichrome staining were performed. NF-κB protein expression was analyzed using the IHC method. Gingival inflammation gene expression of NF-κB, IL-1β, IL-6, p38, and TNF-α was measured using q-RTPCR.

Results

Single and double applications of brazilin cream increased angiogenesis and decreased NF-κB protein expression, in addition to the IL-1β, IL-6, p38, and TNF-α gene expressions.

Conclusion

In a rat gingivitis model, Brazilin cream may function as an anti-inflammatory agent in the gingival tissue.

Antidiabetic, antidyslipidemia, and renoprotector potency of butterfly pea flower extract (Clitorea ternatea L.) in diabetes mellitus and dyslipidemia rats model

Background

Diabetes mellitus (DM) is a long-term condition marked by high blood glucose levels caused by insulin resistance which will lead to complications of other diseases such as dyslipidemia, which also affects the health of the liver and kidneys. Butterfly pea flower (Clitorea ternatea L.) has phenolic and flavonoid compounds which have the potential as herbal medicines for antidiabetics.

Aim

The purpose of this study is to examine the potential of butterfly pea flower extract (BPE) as an antidiabetic, anti-dyslipidemia, and renoprotection.

Methods

In vivo test was performed on Sprague Dawley rats (Rattus norvegicus L.) induced by Streptozotocin-Nicotinamide and High Fat Diet-Propylthiouracil as models of DM and dyslipidemia, and BPE was administered orally (200, 400, and 800 mg/kg BW) for 28 days. glutathione peroxidase (GSH-Px), glutathione S-transferase (GST), tumor necrosis factor-α (TNF-α), nuclear factor-kappa beta (NF-kB), alkaline phosphatase (ALP), liver albumin levels, serum blood urea nitrogen (BUN), serum creatinine, and serum uric acid (UA), were measured by ELISA and colorimetry methods.

Results

Treatment of BPE 800 mg/kg BW increased levels of GSH-Px, GST, albumin, and serum protein. BPE decreased TNF-α, NF-kB, and ALP. BPE also decreased BUN, serum CR, and serum UA.

Conclusion

BPE has the potential to be used as a drug alternative for the treatment of DM and dyslipidemia as well as a hepatoprotective and renoprotective agent.

Antidiabetic and hepatoprotection effect of butterfly pea flower (Clitoria ternatea L.) through antioxidant, anti-inflammatory, lower LDH, ACP, AST, and ALT on diabetes mellitus and dyslipidemia rat

This study explores the antidiabetic and hepatoprotective potential of Butterfly pea flower extract (Clitoria ternatea L.) (CTE) in diabetic and dyslipidemia rat models. Diabetes Mellitus (DM) is a chronic metabolic disorder marked by high levels of blood glucose, which can cause dyslipidemia and liver damage as a result of oxidative stress. CTE, a natural substance, is recognized for its positive attributes, such as anti-inflammatory, antioxidant, anti-diabetic, anti-dyslipidemia, antibiotic, and liver tissue protection capabilities. Dyslipidemia was induced in rats using a high-fat diet (HFD) and propylthiouracil (PTU) for 28 days. DM was induced using streptozotocin (STZ) and nicotinamide (NA). Rats were treated with varying doses of CTE for 28 days, along with glibenclamide and simvastatin. The research showed that CTE raised the levels of SOD, CAT, and liver proteins while lowering the levels of MDA, LDH, ACP, AST, ALT, IL-1β, and CRP in rats with DM and dyslipidemia. This suggests that CTE might be useful for treating DM.

Cisplatin-Induced Kidney Toxicity: Potential Roles of Major NAD+-Dependent Enzymes and Plant-Derived Natural Products

Cisplatin is an FDA approved anti-cancer drug that is widely used for the treatment of a variety of solid tumors. However, the severe adverse effects of cisplatin, particularly kidney toxicity, restrict its clinical and medication applications. The major mechanisms of cisplatin-induced renal toxicity involve oxidative stress, inflammation, and renal fibrosis, which are covered in this short review. In particular, we review the underlying mechanisms of cisplatin kidney injury in the context of NAD+-dependent redox enzymes including mitochondrial complex I, NAD kinase, CD38, sirtuins, poly-ADP ribosylase polymerase, and nicotinamide nucleotide transhydrogenase (NNT) and their potential contributing roles in the amelioration of cisplatin-induced kidney injury conferred by natural products derived from plants. We also cover general procedures used to create animal models of cisplatin-induced kidney injury involving mice and rats. We highlight the fact that more studies will be needed to dissect the role of each NAD+-dependent redox enzyme and its involvement in modulating cisplatin-induced kidney injury, in conjunction with intensive research in NAD+ redox biology and the protective effects of natural products against cisplatin-induced kidney injury.

Enhancement of Antioxidant Activities in Black Soy Milk through Isoflavone Aglycone Production during Indigenous Lactic Acid Bacteria Fermentation

Black soybeans contain high antioxidant compounds such as isoflavone but mainly in glucoside form, with low antioxidant activities. Fermentation by lactic acid bacteria (LAB) can enhance the antioxidant properties, but its ability is strain-dependent. This study aims to study the ability of Indonesian indigenous LAB, Lactiplantibacillus plantarum WGK 4, Streptococcus thermophilus Dad 11, and Lactiplantibacillus plantarum Dad 13, to enhance the antioxidant properties during black soy milk fermentation. Fermentation was carried out at 37 °C for 24 h. Viable cell, acid production, Folin–Ciocalteu assay, antioxidant activity (DPPH), isoflavone aglycone daidzein and genistein, and β-glucosidase activity were measured every six hours. All LAB strains could grow well during the fermentation of black soy milk. Lactiplantibacillus plantarum WGK 4 produced the highest acid (1.50%). All three LAB strains could enhance antioxidant activity (DPPH) from 24.90% to 31.22–38.20%, followed by increased isoflavone aglycone. All strains could increase daidzein and genistein content, ranging from 61% to 107% and 81% to 132%, respectively. All three Indonesian indigenous LAB enhanced antioxidant properties of black soy milk relatively at the same level and potentially could be used as a starter culture of black soy milk fermentation.
