(pedaliaceae) mitigates the 7,12-dimethylbenz(a)anthracene-induced breast tumor burden in rats. JOURNAL OF COMPLEMENTARY & INTEGRATIVE MEDICINE 2024; 0:jcim-2023-0266. [PMID: 38515384 DOI: 10.1515/jcim-2023-0266] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 03/03/2024] [Indexed: 03/23/2024]
Abstract
OBJECTIVES Sesamum indicum L. seeds; rich in zinc and lignans are endowed with antioxidant and immunomodulatory properties which attract research on their anticancer potential. Although many studies have reported the in vitro antitumor potential of S. indicum and its phytoconstituents, much is yet to be known about its in vivo effects. To fill this gap, the effects of dietary supplementation with seeds of S. indicum in 7,12-dimethylbenz(a)anthracene-exposed rats was assessed. METHODS 42 rats aged 30-35 days were randomized into six groups (n=6) as follows: the normal (NOR) and negative (DMBA) control groups were fed with standard diet; the positive control group (DMBA + Zinc) was fed with standard diet supplemented with commercial zinc (0.01 %); the test groups were fed with standard diet supplemented with S. indicum seeds in different proportions (6.25 , 12.5 and 25 %). Breast cancer was induced by a single administration of DMBA (50 mg/kg BW, s.c.) diluted in corn oil. The experiment lasted 20 weeks and afterward, tumor incidence; tumor burden, tumor volume, tumor micro-architecture and some biochemical parameters were evaluated. RESULTS As salient result, 100 % of rats in the DMBA group developed tumors, while rats feed with rat chow supplemented with S. indicum seeds (25 %) had a reduced incidence of tumors (33.3 %) and tumor volume (2.71 cm3 in sesame 25 % vs. 4.69 cm3 in the DMBA group, p˂0.01). The seeds (25 %) also slowed DMBA-induced neoplasm expansion in mammary ducts as compared to rats of DMBA group. CONCLUSIONS In summary, supplementation with S. indicum seeds slowed breast tumorigenesis via its antioxidant capacity.

The Short-Term Effects of Pistacia Lentiscus Oil and Sesame Oil on Liver and Kidney Pathology of Rats and Human Cancer Cell Lines. Galen Med J 2021; 9:e2001. [PMID: 34466622 PMCID: PMC8343819 DOI: 10.31661/gmj.v9i0.2001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2020] [Revised: 09/11/2020] [Accepted: 10/10/2020] [Indexed: 11/16/2022] Open
Abstract
Background Vegetable oils recently have been evaluated in many tissues. Pistacia lentiscus (mastic) of the Anacardiaceae family and Sesamum indicum (sesame) of the Pedaliaceae family are conventionally used in the management of gastrointestinal, lung, and skin illnesses. This assay attempts to determine if the oral usage of mastic and sesame oils has any short-term toxic effects in vivo on the rat and evaluate the human anticancer effect in vitro. Materials and Methods Twenty-one male Sprague-Dewley rats were assigned to three groups randomly: (A) control, (B) mastic oil (400 mg/kg), and (C) sesame oil (2cc/kg). The effects of these oils were investigated by determining histopathological and stereological parameters after six days, and the anticancer effects were evaluated on SW48, HepG2 human cell lines. Results A mild chronic interstitial inflammation was seen in just one kidney of mastic oil group (B) and the other ones were normal. In the sesame oil group (C), mild chronic interstitial inflammation was seen in six kidneys. In the liver samples of both groups, there were no specific pathological findings. Different concentrations of mastic oil (0.1%-5%) reduced the cell viability of SW48, HepG2, HEK293t, and human fat cells. Conclusion Mastic and sesame oils have some side-effects on the kidney and might not be safe at high doses in rats. Sesame oil did not have any toxic effect on HepG2 and HEK293t human cancer cells. Mastic oil treatment has inhibited specific SW48 cells, so this oil seems to be a good adjuvant to chemotherapy in colon treatments.

Abstract
Cisplatin is an effective chemotherapeutic agent that is used for the treatment of a variety of cancers; however, its nephrotoxicity limits the use of this drug. In the present study, we examined whether paeonol, a major compound of Moutan Cortex, has protective effects on cisplatin-induced acute renal failure in mice. To accomplish this, Balb/c mice (6 to 8 wk of age, weighing 20 to 25 g) were administered, Moutan Cortex (300 mg/kg) or paeonol (20 mg/kg) once a day. At day 4, mice received cisplatin (30, 20, or 10 mg/kg) intraperitoneally. The paeonol-treated group showed marked attenuation of serum creatine and blood urea nitrogen levels as well as reduced levels of proinflammatory cytokines and nitric oxide when compared to the control group. In addition, the paeonol-treated group showed prolonged survival and marked attenuation of renal tissue injury. Taken together, these results demonstrated that paeonol can prevent the renal toxic effects of cisplatin.

Abstract
Heavy metals become toxic when they are not metabolized by the body and accumulate in the soft tissue. Chelation therapy is mainly for the management of heavy metal-induced toxicity; however, it usually causes adverse effects or completely blocks the vital function of the particular metal chelated. Much attention has been paid to the development of chelating agents from natural sources to counteract lead- and iron-induced hepatic and renal damage. Sesame oil (a natural edible oil) and sesamol (an active antioxidant) are potently beneficial for treating lead- and iron-induced hepatic and renal toxicity and have no adverse effects. Sesame oil and sesamol significantly inhibit iron-induced lipid peroxidation by inhibiting the xanthine oxidase, nitric oxide, superoxide anion, and hydroxyl radical generation. In addition, sesame oil is a potent inhibitor of proinflammatory mediators, and it attenuates lead-induced hepatic damage by inhibiting nitric oxide, tumor necrosis factor-α, and interleukin-1β levels. Because metal chelating therapy is associated with adverse effects, treating heavy metal toxicity in addition with sesame oil and sesamol may be better alternatives. This review deals with the possible use and beneficial effects of sesame oil and sesamol during heavy metal toxicity treatment.

Abstract
Oxaliplatin, an anticancer drug commonly used to treat colorectal cancer and other tumors, has a number of serious side effects, most notably neuropathy and ototoxicity. To gain insights into its ototoxic profile, oxaliplatin was applied to rat cochlear organ cultures. Consistent with it neurotoxic propensity, oxaliplatin selectively damaged nerve fibers at a very low dose 1 μM. In contrast, the dose required to damage hair cells and spiral ganglion neurons was 50 fold higher (50 μM). Oxailiplatin-induced cochlear lesions initially increased with dose, but unexpectedly decreased at very high doses. This non-linear dose response could be related to depressed oxaliplatin uptake via active transport mechanisms. Previous studies have demonstrated that axonal degeneration involves biologically active processes which can be greatly attenuated by nicotinamide adenine dinucleotide (NAD+). To determine if NAD+ would protect spiral ganglion axons and the hair cells from oxaliplatin damage, cochlear cultures were treated with oxaliplatin alone at doses of 10 μM or 50 μM respectively as controls or combined with 20 mM NAD+. Treatment with 10 μM oxaliplatin for 48 hours resulted in minor damage to auditory nerve fibers, but spared cochlear hair cells. However, when cochlear cultures were treated with 10 μM oxaliplatin plus 20 mM NAD+, most auditory nerve fibers were intact. 50 μM oxaliplatin destroyed most of spiral ganglion neurons and cochlear hair cells with apoptotic characteristics of cell fragmentations. However, 50 μM oxaliplatin plus 20 mM NAD+ treatment greatly reduced neuronal degenerations and hair cell missing. The results suggested that NAD+ provides significant protection against oxaliplatin-induced neurotoxicity and ototoxicity, which may be due to its actions of antioxidant, antiapoptosis, and energy supply.

Abstract
Cyclosporine A (CsA) is a drug used in autoimmune disorders and organ transplantations. Omega 3 fatty acids (O-3) and sesame oil (SO) have antioxidant properties. We aimed to investigate and compare the protective effects of O-3 and SO against CsA-induced nephrotoxicity. Seven groups of male Wistar albino rats were included in the study. In group 1 (control), saline was administered, and in group 2, CsA (subcutaneously) was administered. In group 3, CsA+SO (orally; p.o.) was given; in group 4, CsA+O-3 (p.o.) was given; and in group 5, CsA+SO+O-3 was given. In group 6, SO was administered, and in group 7, O-3 was administered. After 15 days of treatment, kidneys were excised. Histopathological evaluation, apoptotic cell count, and renal/hepatic function tests were performed. In group 2, vacuolar degeneration and necrosis of tubular cells as well as hemorrhagic foci were observed; the apoptotic cell number was higher than in the control (P < 0.001). In groups 3, 4, and 5, tubular scores and apoptotic cell count were lower than in group 2 (P < 0.01 and P < 0.001, respectively). In groups 6 and 7, healthy renal histology and a few apoptotic cells were determined. In groups 2, 3, 4, and 5, blood urea nitrogen was higher and albumin was lower than in the control (P < 0.001). Liver enzymes were unchanged. O-3/SO showed similar protective effects against CsA-induced nephrotoxicity, as revealed by a remarkable decrease in histopathological changes and apoptotic cell count. However, impaired renal function tests were not improved with O-3/SO treatment. SO and O-3 can be used as chemoprotectants against CsA.

Abstract
UNLABELLED Although cisplatin is one of the most efficient chemotherapeutic agents for the treatment of solid tumors, frequently observed nephrotoxicity has limited its use in several patients. MATERIALS AND METHODS The protective effect of Glycine max (GM) and Chrysanthemum indicum (CM) extracts on cisplatin-induced apoptosis in human proximal tubular HK-2 cells was evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), Hoechst 33342, and propidium iodide assays. Reactive oxygen species (ROS) were determined by flow cytometry with 2,7-dichlorofluorescein diacetate (DCFH(2)-DA). RESULTS Cisplatin-induced renal cell toxicity through the induction of hydrogen peroxide (H(2)O(2)) and hydroxyl radical (OH(•-)). CM extract protected cisplatin-induced apoptosis by its anti-oxidant activity against H(2)O(2) and OH(•-), while GM extract scavenged only H(2)O(2). Furthermore, GM and CM extracts protect renal cells without significant interfering effect on cisplatin toxicity in lung cancer H460 and melanoma G361 cells. CONCLUSION GM and CM extracts exhibited a promising protective effect on cisplatin-induced nephrotoxicity which could benefit the development for nephroprotective approaches.

Abstract
Sesame oil could be considered as a potent antioxidant and dietary supplement. It possesses antimutagenic, anti-inflammatory and anti-cardiac toxicity. In the view of available findings, the current study focused on determining the protective effects of sesame oil on 4-Nitroquinoline-1-oxide (4-NQO) -induced oxidative DNA damage and lipid peroxidation (LPO) in rats. Seven groups of Wistar albino rats each with 6 either sex were used. Groups were given vehicle control and sesame oil alone orally and 4-NQO (30 mg/kg) by intraperitoneal injection. Following the four dose levels (1, 2, 4, and 8 ml/kg orally), sesame oil plus 4-NQO were also tested. After 24 hours of 4-NQO injection, blood samples were drawn by venipuncture. DNA damage (8-hydroxy-2-deoxy guanosine; 8-OHdG) and LPO were estimated. LPO from the 4-NQO-treated group was 2.5-fold higher than that of the control LPO. Pretreatment with sesame oil reduced this by 16-61%. 8-OHdG DNA damage from 4-NQO was found to be 3-fold higher than that of controls. Pretreatment with sesame oil effectively protected against DNA damage in a dose-dependent fashion. This study indicates that the antioxidant, sesame oil, effectively protected DNA damage and LPO induced by 4-NQO.

Abstract
AIM The rhizome of turmeric, Curcuma longa (CL), is a herbal medicine used in many traditional prescriptions. It has previously been shown that CL treatment showed greater than 47% recovery from cisplatin-induced cell damage in human kidney HEK 293 cells. This study was conducted to evaluate the recovery mechanisms of CL that occur during cisplatin induced nephrotoxicity by examining the genome wide mRNA expression profiles of HEK 293 -cells. METHOD Recovery mechanisms of CL that occur during cisplatin-induced nephrotoxicity were determined by microarray, real-time PCR, immunofluorescent confocal microscopy and Western blot analysis. RESULTS The results of microarray analysis and real-time PCR revealed that NFκB pathway-related genes and apoptosis-related genes were down-regulated in CL-treated HEK 293 cells. In addition, immunofluorescent confocal microscopy and Western blot analysis revealed that NFκB p65 nuclear translocation was inhibited in CL-treated HEK 293 cells. Therefore, the mechanism responsible for the effects of CL on HEK 293 cells is closely associated with regulation of the NFκB pathway. CONCLUSION CL possesses novel therapeutic agents that can be used for the prevention or treatment of cisplatin-induced renal disorders.

Abstract
Gentamicin, an aminoglycoside antibiotic, is widely used in the treatment of Gram-negative infections; however, dose-limiting nephrotoxicity restricts its optimal use. We investigated the effect of a daily sesame oil supplement on oxidative-stress-associated renal injury induced by a single daily dose of gentamicin in rats. Renal injury was induced by a single subcutaneous daily dose of gentamicin (100 mg kg(-1) d(-1) for 7 days), and then the effects of oral sesame oil (0.25, 0.5, and 1 mL kg(-1) d(-1) for 7 days) on renal injury, oxidative stress, hydroxyl radical, superoxide anion, and NO were assessed after treatment. Sesame oil inhibited gentamicin-induced renal injury, lipid peroxidation, hydroxyl radical, and superoxide anion, as well as NO production. In addition, sesame oil inhibited xanthine oxidase activity and inducible NOS expression in gentamicin-challenged rats. We hypothesize that a daily sesame oil supplement attenuates oxidative-stress-associated renal injury by reducing oxygen free radicals and lipid peroxidation in gentamicin-treated rats.

Abstract
The root cortex of Paeonia suffruticosa Andrews (PS) is a crude Chinese drug used in many traditional prescriptions. This study was conducted to evaluate the recovery mechanisms induced by PS in HEK 293 cells treated with cisplatin. Previous studies revealed that 1μg/ml PS treatment showed greater than 20% recovery of 14μM cisplatin-induced 50% loss of cell proliferation (IC(50)) determined by mitochondrial activity MTS assay in HEK 293 cells (Sohn et al., 2009). In the present study, the effects of PS on gene expression profiles in stimulated HEK 293 cells were evaluated by oligonucleotide microarray and real-time RT-PCR. The results of the microarray analysis and real-time RT-PCR revealed that DNA repair- and cell proliferation-related genes were up-regulated in PS-treated HEK 293 cells. The mechanism responsible for the effects of PS on HEK 293 cells is closely associated with the regulation of DNA repair and cell proliferation. Thus, PS possesses novel therapeutic potential that could be used for the prevention or treatment of cisplatin-induced nephrotoxicity.

Abstract
The goal of this study was to quantitatively determine the recovery effects of herbal medicines (HM) on the cisplatin-induced nephrotoxicity. In the present study, the recovery effects of 239 HM on HEK 293 cells that had been damaged by cisplatin were evaluated by a mitochondrial activity MTS assay. After the first round of screening, candidate HM were selected based on a recovery rate of greater than 20%. The efficacy of the selected herbs was then determined by dose response kinetic analysis. Of the extracts evaluated, 7 HM (Paeonia suffruticosa (PS), Curcuma longa (CL), Centipeda minima (CM), Loranthus parasiticus (LP), Pulsatilla dahurica (PD), Sinapis alba (SA), and Scutellaria barbata (SB)) had a strong recovery effect on cisplatin-induced damage in HEK 293 cells. An LDH assay showed that LP, CM, SB, CL, SA, and PS had the best recovery effect, whereas a comet assay indicated that PS, SB, SA, PD, and CL had the best recovery effect. Taken together, these results suggest that SB, CL, PS, and SA are the best candidate HM for the recovery of cisplatin-induced nephrotoxicity. Therefore, additional studies should be conducted to determine if these HM possess novel therapeutic agents that can be used for the prevention or treatment of renal disorders.

Abstract
We examined the protective effects of sesamol against acute gastric mucosal damage induced in rats by nonsteroidal anti-inflammatory drug diclofenac (DLF). We also measured the ulcer index, nitrite, iNOS, lipid peroxidation, hydroxyl radical, superoxide anion, reduced glutathione levels, prostaglandin E2, mucus, and cyclooxygenase activity in the rat mucosa. Sesamol attenuated gastric ulcer, nitrite, and iNOS in DLF-treated stomachs. Sesamol reduced mucosal lipid peroxidation and hydroxyl radical levels; however, neither DLF nor sesamol affected mucosal superoxide anion production. In addition, sesamol significantly maintained the reduced mucosal glutathione levels in DLF-treated stomachs of rats. Sesamol did not affect mucosal mucus production, but it further decreased DLF-induced mucosal prostaglandin E2 generation and cyclooxygenase activity. Therefore, sesamol might protect gastric mucosa against DLF-induced injury by inhibiting hydroxyl radical-associated lipid peroxidation. In addition, the cyclooxygenase pathway may not be involved in sesamol's gastric mucosal protection.

Abstract
AIM OF THE STUDY Ginseng, the root of Panax ginseng C.A.Meyer (Araliaceae), is one of the most widely used Chinese herbs with hypotensive and cardiotonic actions for thousands of years, but the underlying mechanisms have not been well determined. Ginsenoside, the effective components of ginseng, has anti-inflammatory and anti-oxidative effects. Cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) are key enzymes in inflammation and oxidative stress, respectively, which have close interaction, aggravating their damaging effects. This study investigated whether COX-2 interacted with iNOS in vascular endothelial lesion and the protective effect of ginsenoside. MATERIALS AND METHODS SD male rats were fed with high l-methionine (3%, w/w) to induce vascular endothelial lesion, and the rats in ginsenoside group were fed ginsenoside solution (0.8 mg kg(-1)d(-1)). The mRNA expression and protein contents of COX-2 and iNOS were detected by RT-PCR and Western blotting, respectively. The interaction between COX-2 and iNOS was analyzed by co-immunoprecipitation and laser confocal microscopy. The content of NT, a specific marker of peroxynitrite, was evaluated by Western blotting. The morphological changes of vascular endothelium were observed. RESULTS Compared with control group, the transcription and protein levels of both COX-2 and iNOS increased obviously and their interaction enhanced significantly in model group, in accord with the increased NT content and the pathological alterations of aorta. In ginsenoside group, all these alterations were attenuated significantly (P < 0.01 or P < 0.05). CONCLUSIONS It is proved that there exists interaction between COX-2 and iNOS, aggravating endothelial lesion through peroxynitrite and ginsenoside might antagonize their interaction, playing a protective role.
