The critical role of SETDB1-mediated CCND1/PI3K/AKT pathway via p53-RS di-methylation at K370 in the proliferation of WRL68 cells induced by nicotine.

Abstract
Constituents of cigarette smoke are known to be carcinogens. Additionally, there is mounting evidence that the liver is an organ susceptible to tobacco carcinogenicity. Nicotine, the primary constituent of tobacco, plays a role in cancer progression. In our previous study, it was found that nicotine enhances the proliferation of a human normal fetal hepatic (WRL68) cell due to the activation of p53 mutation at Ser249 (p53-RS)/STAT1/CCND1 signaling pathway. Here, we further elucidated the mechanism of regulating this pathway. Firstly, dose-dependent increase of SETDB1 protein level in WRL68 cells upon exposure to nicotine (1.25, 2.5, and 5 μM), significantly enhanced cellular proliferation. In addition, the upregulation of SETDB1 protein was necessary for the nuclear translocation of p53-RS to establish a ternary complex with STAT1 and SETDB1, which facilitated p53-RS di-methylation at K370 (p53-RS/K370me2). After that, the activation of CCND1/PI3K/AKT pathway was initiated when STAT1 stability was enhanced by p53-RS/K370me2, ultimately resulting in cell proliferation. Altogether, the study revealed that the increase in SETDB1 expression could potentially have a significant impact on the activation of CCND1/PI3K/AKT pathway through p53-RS/K370me2, leading to the proliferation of WRL68 cells induced by nicotine, which could contribute to hepatocellular carcinoma for smokers. Besides, the results of this study provided a foundation for the development of anticancer therapies for cancers associated with tobacco use.

Abstract
Cigarette smoking (CS) is a crucial modifiable risk of developing several human diseases and cancers. It causes lung, bladder, breast, and esophageal cancers, respiratory disorders, as well as cardiovascular and metabolic diseases. Because of these adverse health effects, continual efforts to decrease the prevalence and toxicity of CS are imperative. Until the past decades, the impacts of natural compounds have been under investigation on the harmful effects of CS. Turmeric (Curcuma longa), a rhizomatous herbaceous perennial plant that belongs to the Zingiberaceae family, is the main source of curcumin. This review is an attempt to find out the current knowledge on CS's harmful effects and protective potential of curcumin in the pulmonary, liver, brain, gastrointestinal, and testis organs. According to the present review, simultaneous consumption of curcumin and CS can attenuate CS toxicities including chronic obstructive pulmonary disease, gastrointestinal toxicity, metabolic diseases, testis injury, and neurotoxicity. Moreover, curcumin suppresses carcinogenesis in the skin, liver, lungs, breast, colon, and stomach. Curcumin mediates these protective effects through antioxidant, anti-inflammatory, anti-apoptotic, and anti-carcinogenicity properties.

Abstract
Nicotine is the most abundant ingredient in cigarette smoking and has serious side effects on the lung, heart, reproductive system, and many other human organs. Saponins extracted from many plants exhibit multiple biological actions such as anti-cancer effects. Therefore, the possible protective effect of fenugreek saponin (FS) and nanofenugreek saponin (NFS) against nicotine-induced toxicity in male rats was investigated in this study. Animals were divided into a control group and the nicotine (1.5 mg/kg/day), FS (25, 50, and 100 mg/kg/day), or/and NFS (20, 40, and 80 mg/kg/day) administered groups. Micronucleus assay, histopathological, and sperm abnormality examinations as well as measurement of the acetylcholinesterase (AChE) gene expression were conducted. Our findings revealed that nicotine treatment induced significant increases in the incidence of micronucleus, sperm abnormalities, and expression levels of AChE in addition to inducing histopathological changes in rat testis. On the other hand, administration of FS or NFS with nicotine significantly decreased the incidence of micronuclei and the percentage of sperm abnormalities as well as the expression levels of AChE gene. Moreover, nicotine-induced histological alterations were reduced by given FS or NFS with nicotine. In conclusion, nicotine-induced sperm abnormalities, chromosomal damage, and histological injuries were mitigated by administration of FS or NFS with nicotine, and thus, FS and NFS could be used as ameliorating agents against nicotine toxicity.

Nutrients 2022; 14:nu14091756. [PMID: 35565726 PMCID: PMC9103831 DOI: 10.3390/nu14091756] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 04/20/2022] [Accepted: 04/21/2022] [Indexed: 12/23/2022] Open
Abstract
Procyanidin B2 (PCB2), a natural flavonoid, has been demonstrated to exert anti-oxidation and anti-inflammatory effects on hepatic diseases. Increasing evidence shows the hepatoxicity of nicotine. However, whether PCB2 protects against nicotine-induced hepatoxicity and the underlying mechanisms remains uncharacterized. Here, we reported that nicotine promoted hepatocyte pyroptosis, as evidenced by the elevation of propidium iodide (PI)-positive cells, the activation of Caspase-1 and gasdermin D (GSDMD), the enhanced expression of NOD-like receptor containing pyrin domain 3 (NLRP3) and the increased release of lactate dehydrogenase (LDH), interleukin (IL)-1β and IL-18. The silencing of GSDMD by small interfering RNA (siRNA) efficiently inhibited the release of LDH and the secretion of IL-1β and IL-18. In addition, rosiglitazone (RGZ) prevented hepatocyte pyroptosis induced by nicotine. Furthermore, we showed that PCB2 attenuated nicotine-induced pyroptosis through the activation of peroxisome proliferator-activated receptor-γ (PPARγ) in hepatocytes. Moreover, administration of PCB2 ameliorated liver injury and hepatocyte pyroptosis in nicotine-treated mice. Hence, our findings demonstrated that PCB2 attenuated pyroptosis and liver damage in a PPARγ-dependent manner. Our results suggest a new mechanism by which PCB2 exerts its liver protective effects.

Abstract
Commiphora myrrha, located in the tropical zone, is a widely used tree for medicinal purposes in the Arabian Peninsula and a large part of Africa. In this research, cytogenotoxic effects of the commercially available Commiphora myrrha essential oil (myrrh) were studied using micronucleus (MN), comet, and total oxidant (TOS), and total antioxidant (TAS) assays on human peripheral lymphocytes under in vitro conditions. In addition, pure pBR322 plasmid DNA was used to investigate DNA damaging/protecting activity of the essential oil. Finally, a bacterial reversion (Ames) test was performed using Salmonella typhimurium mutant strains TA98 and TA100 to determine the potential effect of the agent in the induction of gene mutations. The high concentration of Commiphora myrrha (0.125 µL/mL) induced MN formation significantly compared to the untreated control in both treatment times (24 or 48 h). Only at the highest concentration, nuclear division index (NDI) values were found lower than the controls. In the Comet test performed on healthy lymphocytes, only the highest concentration of myrrh caused significant increases in the percentage of damaged cells and genetic damage index (GDI) values. Myrrh oil showed no significant mutagenic effect on mutant Salmonella strains. In addition, the substance did not directly damage plasmid DNA but also protected DNA against damaging factors such as H2O2 and UV. Finally, in the TAS and TOS assays, no significant differences on the oxidative stress parameters were found in cell culture compared to the control. The results of this study showed that myrrh oil exerts cytogenotoxic risk only at higher concentrations.

Abstract
Nicotine is an active pharmacological ingredient in cigarette smoke, which may negatively influence the male reproductive system and fertility. This study aims to investigate the effect of fractionated low-dose radiation (fractionated-LDR) and/or ellagic acid (EA) on nicotine-induced hormonal changes and testicular toxicity in rats. Nicotine was administrated orally (1 mg/kg) for 30 days, afterward, rats were treated with LDR (2 × 0.25 Gy/1-week interval), EA (10 mg/kg, 14 consecutive days p.o.), or a combination of both fractionated-LDR and EA. Rats were sacrificed 24 h after the last dose of treatment, then testes were dissected for histopathology examination, along with some biochemical parameters in serum and testicular tissue were evaluated. Nicotine-induced oxidative stress was evidenced by an increase in testicular thiobarbituric acid reactive substances (TBARS) and a decrease in reduced glutathione (GSH) content. Additionally, the activities of testicular androgenic enzymes were decreased, and the activity of serum lactate dehydrogenase (LDH) was significantly increased. The hormonal changes were verified by a noticeable reduction in follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone serum levels. Histological evaluation revealed that the testicular seminiferous tubules structure was distorted. On the contrary, fractionated-LDR plus EA attenuated the negative changes caused by nicotine observed through biochemical and histological findings. Accordingly, the exposure to fractionated-LDR combined with EA may be a promising candidate for treating hormonal changes and testicular toxicity caused by nicotine.

Abstract
Background:
Ellagic Acid (EA) is a polyphenolic compound that is classified in the natural
antioxidants group. Polyphenolic compounds that exert antioxidant activity possess particular importance
for scientists, food producers and consumers due to their positive effects on human health. However,
despite considerable evidence that EA shows antigenotoxic activity by binding to DNA, there is no
systematic genotoxicity study of this substance, which can covalently bind to DNA. This study aims to
reveal the possible genotoxic activity of EA using widely accepted assays for the assessment of DNA
clastogenic activity: sister chromatid exchange, chromosome aberration, micronucleus and comet assays
as well as to predict the interactions among EA and DNA through molecular docking.
Methods:
Different assays were carried out to identify the clastogenic activity of EA on human lymphocyte
DNA using Sister Chromatid Exchange (SCE), Chromosome Aberration (CA), Micronucleus (MN)
and single-cell gel electrophoresis (SCGE/comet) assays. For this aim, human peripheral blood lymphocytes
were treated with EA (60, 80 and 100 μg/ml) for 24 and 48 hrs in the SCE, CA and MN assays
and for 1 hr in the comet assay. Furthermore, molecular docking experiments were also performed to
calculate the binding energy of EA on human B-DNA structure (B-DNA dodecamer) as well as to predict
noncovalent interactions among these macromolecules.
Results:
At the concentrations and treatment times (24- or 48-hr) tested, EA did not induce either SCE or
Chromosome Aberrations (CAs) as compared to the negative and solvent controls. Although EA slightly
increased the percentage of Micronucleated Binuclear (%MNBN) cells as well as the percentage of Micronucleus
(%MN) in 24 or 48-hr treatment periods at all concentrations, this increase was not statistically
significant as compared to both controls. The effect of EA on DNA replication (nuclear division) was determined
by the Proliferation Index (PI), the Nuclear Division Index (NDI) and the Mitotic Index (MI). No
statistically significant differences were observed in the PI or NDI in 24- or 48-hr treatment periods in
human lymphocyte cultures treated with EA at various concentrations. EA generally had no significant
effect on the MI, as observed with the PI and NDI.
Discussion:
Although the concentrations of 60 and 80 μg/mL at a 24-hr treatment period and the concentrations
of 60 μg/mL and 100 μg/mL at 48-hr treatment period generally decreased the MI, those decreases
were not statistically significant when compared to negative and solvent controls. Moreover, none of the
concentrations of EA tested in this study were able to increase DNA damage determined by the tail DNA
length, %DNA in tail and tail moment parameters in the comet assay. Although the amount of DNA damage
in the comet assay decreased with increasing concentrations of EA, this decrease was not statistically
significant as compared to both controls. However, molecular docking experiments interestingly showed
that the binding free energy of EA with B-DNA was -7.84 kcal/mol-1, indicating a strong interaction between
the two molecules.
Conclusion :
Although the findings of our study show that EA does not have genotoxic potential in human
chromosomes, molecular docking experiments revealed strong hydrogen bonding between EA and
B-DNA molecules. Therefore, it has been proposed that the prevailing information suggesting that the
molecules that bind to DNA cause genotoxic effects should be reconsidered from a wider perspective.

Abstract
This study describes the effects of royal jelly (RJ) on testicular injury induced by nicotine (NIC) in mice. Thirty-six male BALB/c mice were randomly divided into six groups (n = 6). Group 1 received normal saline, group 2 received 100 mg/kgBW/day RJ, groups 3 and 4 received NIC at doses of 0.50 and 1.00 mg/kgBW/day, respectively, and groups 5 and 6 received NIC at doses of 0.50 and 1.00 mg/kg BW/day, respectively, plus RJ. Following 35 days, the serum level of testosterone, histopathological changes, germ cell apoptosis, proliferating cell nuclear antigen (PCNA), malondialdehyde (MDA) content, and antioxidant indexes including total antioxidant capacity (TAC) and catalase (CAT) activity were determined. In addition, the mitochondria-dependent apoptosis was investigated by assessing the Bcl-2, p53, and Caspase-3 mRNA levels expression by reverse transcription-PCR (RT-PCR). Compared to NIC receiving groups, the concomitant administration of RJ could protect the testosterone reduction and histological damages. After RJ treatment, the level of tissue MDA content decreased, while tissue TAC and CAT levels were remarkably increased compared to NIC-exposed groups. Remarkable higher TUNEL-positive germ cells and low PCNA index were observed in NIC receiving groups. Besides, the expression level of Bcl-2 was significantly higher and the p53 and Caspase-3 levels were significantly lower in the RJ co-administration groups than NIC-only receiving groups. Our results confirmed that RJ effectively protects the testis against NIC evoked damages by antioxidant and anti-apoptotic effects involving the up regulation of the antioxidant status, mitochondria-dependent apoptosis pathway prevention, and the proliferating activity improvement.

Diabetic people are advised to choose low-glycemic food and herbal products to control diabetes. This study aims to examine the synergistic effects of aqueous root Salep ofGymnadenia orchidis Lindl and pumpkin seed powder on Streptozotocin induced diabetic mice. METHODS Out of 6 groups, animals in 2 groups were kept as control and rest 4 groups were made diabetic by Streptozotocin. Animals in one diabetic group were supplemented with effective dose (200 mg/kg of body weight) of root Salep, one with pumpkin seed powder (5%) mixed food, and another with Salep and pumpkin seed food. Changes in various biochemical parameters, DNA damage and liver and kidney structures were noted after 21 days treatment. RESULTS Salep with pumpkin seed supplementation significantly normalized the alterations of different biochemical parameters of diabetic mice. The DNA damage in blood cells of diabetic mice was recovered by this supplementation. Terpenoids of root Salep and anti-oxidants of pumpkin seed may play the active role against diabetes. CONCLUSION The root Salep and pumpkin seed synergistically prevent diabetic complications and could be better supplementation against type-2 diabetes.

Abstract
The present study was conducted to evaluate the ameliorative role of pumpkin seed oil (PSO) against potential adverse effects of bisphenol-A (BPA) in male mice. BPA was administered to the mice orally at a dose of 50 mg/kg body weight once a day for 28 successive days. While, PSO was administered to the mice orally at 1 mL/kg b w either before, with or after treatment of BPA, once a day for 28 successive days. The studied parameters were DNA damage evaluation using comet assay in liver and testes cells and micronucleus test in bone marrow; and histopathological examination of liver and testes tissues. Results revealed that BPA induced DNA damage in tested cells and marked histopathological alterations in liver and testes. In contrast, PSO treatments alleviated DNA damage and improved the histopathological alterations in liver and testes tissues. Furthermore, administration of mice with the PSO before BPA treatment was the best regimen in the alleviation of the adverse effects of BPA, followed by administration of PSO after then with treatment of BPA. It can be concluded that PSO may has a protective role against BPA genotoxicity and histopathological alterations in male mice.

Abstract
Prenatal ethanol exposure causes the most frequent preventable birth disorder, fetal alcohol spectrum disorder (FASD). The effect of turmeric extracts in rescuing an ethanol-induced developmental defect using zebrafish as a model was determined. Ethanol-induced oxidative stress is one of the major mechanisms underlying FASD. We hypothesize that antioxidant inducing properties of turmeric may alleviate ethanol-induced defects. Curcuminoid content of the turmeric powder extract (5 mg/mL turmeric in ethanol) was determined by UPLC and found to contain Curcumin (124.1 ± 0.2 μg/mL), Desmethoxycurcumin (43.4 ± 0.1 μg/mL), and Bisdemethoxycurcumin (36.6 ± 0.1 μg/mL). Zebrafish embryos were treated with 100 mM (0.6% v/v) ethanol during gastrulation through organogenesis (2 to 48 h postfertilization (hpf)) and supplemented with turmeric extract to obtain total curcuminoid concentrations of 0, 1.16, 1.72, or 2.32 μM. Turmeric supplementation showed significant rescue of the body length at 72 hpf compared to ethanol-treated embryos. The mechanism underlying the rescue remains to be determined.

Abstract
Objective: Smoking is the leading preventable cause of various diseases such as lung cancer, chronic obstructive pulmonary disease and cardiovascular disease. Nicotine, one of the major toxic components of tobacco, contributes to the pathogenesis of different diseases. Methods: Given the controversy about nicotine toxicity, the present study was conducted to determine apoptotic effects of nicotine on the heart, kidney, lung and liver of male mice. Real-time PCR was performed to identify mRNA expression changes in apoptotic-related genes between nicotine treated and control mice. Result: In the heart and lung, nicotine caused significant decrease in P53, Bax and Caspase-3 mRNA expression levels compared to the control group. However, in the kidney and liver, the result was significant increase in Bax, Caspase-2, Caspase-3 and a significant decrease in P53 mRNA expression (p<0.01). DNA fragmentation assays indicated no fragmentation in the heart and lung, but in the kidney and liver of nicotine treated mice, isolated DNA was fragmented. Conclusion: Our study provided insight into the molecular mechanisms of nicotine anti-apoptotic effects on the heart and lung as well as pro-apoptotic effects on kidney and liver via a P53-independent pathway.

Curcumin protects against nicotine-induced stress during protein malnutrition in female rat through immunomodulation with cellular amelioration. Mol Biol Rep 2015; 42:1623-37.

Abstract
Nicotine aggravates many chronic inflammatory disorders in females under the protein-malnourished conditions because women are more susceptible to nicotine-induced diseases due to their low innate immunity. Although curcumin have been found to obliterate the nicotine-induced disorders through its anti-nicotinic activity under the protein-malnourished condition, the exact mechanism of protective action of curcumin is still unclear. Female Wister rats maintained under the normal and protein-restricted diets in two separate groups were injected with the effective dose of nicotine-tartrate (2.5 mg/kg body weight/day, subcutaneously) and supplemented with the effective dose of curcumin (80 mg/kg body weight/day, orally) for 21 days. The morphology of red blood cells (RBCs), molecular docking, lipid profile and activities of antioxidant enzymes in tissues, cytokines profiling (T helper cell type 1; and T helper cell type 2), mRNA and protein expression of cytokines, transcription factors (activator protein 1), regulatory molecule (P(53)), growth factors (Granulocyte-macrophage colony-stimulating factor; Transforming growth factor beta) were determined to establish the mechanism of actions of curcumin against the nicotine-mediated stress in the protein-malnourished rats. This study revealed that curcumin bound to the Histidine 87 residues of haemoglobin with a greater binding affinity and significantly protected the RBCs against nicotine-induced damage. Furthermore, the nicotine-mediated disruption of Th1/Th2 balance through upregulation and downregulation of different factors was effectively restored by curcumin under the protein-malnourished conditions. The study demonstrated that curcumin was a potent protective compound against the nicotine-induced stress and offered a probable biochemical and immunomodulatory mechanism of protective action of curcumin.

Abstract
Background: Nicotine is a major pharmacologically active substance in cigarette smoke. It is mainly metabolized in liver and causes devastating effects. Crocin is the chemical ingredient primarily responsible for the color of saffron. It has different pharmacological effects such as antioxidant and anticancer. This study was designed to evaluate the protective role of crocin against nicotine on the liver of mice. Methods: Forty-eight mice were equally divided into 8 groups; control (normal saline), nicotine (2.5 mg/kg), crocin (12.5, 25 and 50 mg/kg) and crocin plus nicotine treated groups. Saline, crocin, nicotine and crocin/nicotine (once a day) were intraperitoneally injected for 4 weeks. The liver weight and histology, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and serum nitric oxide levels have been studied. Results: The results indicated that nicotine administration significantly decreased liver weight (48.37%) and increased the mean diameter of hepatocyte (239%), central hepatic vein (28.45%), liver enzymes level (ALP 29.43%, AST 21.81%, ALT 21.55%), and blood serum nitric oxide level (57.18%) compared to saline group (P < 0.05). However, crocin and crocin plus nicotine administration significantly boosted liver weight (49.54%) and decreased the mean diameter of hepatocyte (40.48%), central hepatic vein (15.44%), liver enzymes (ALP 22.02%, AST 19.05%, ALT 23.11%), and nitric oxide levels (35.80%) in all groups compared to nicotine group (percentages represent the maximum dose) (P < 0.05). Conclusions: Crocin showed its partly protective effect against nicotine-induced liver toxicity.

Abstract
The color of turmeric (薑黃 jiāng huáng) is because of a substance called curcumin. It has different pharmacological effects, such as antioxidant and anti-inflammatory properties. Nicotine is a major pharmacologically active substance in cigarette smoke. It is mainly metabolized in the liver and causes devastating effects. This study was designed to evaluate the protective role of curcumin against nicotine on the liver in mice. Forty-eight mice were equally divided into eight groups; control (normal saline), nicotine (2.5 mg/kg), curcumin (10, 30, and 60 mg/kg) and curcumin plus nicotine-treated groups. Curcumin, nicotine, and curcumin plus nicotine (once a day) were intraperitoneally injected for 4 weeks. The liver weight and histology, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and serum nitric oxide levels have been studied. The results indicated that nicotine administration significantly decreased liver weight and increased the mean diameter of hepatocyte, central hepatic vein, liver enzymes level, and blood serum nitric oxide level compared with the saline group (p < 0.05). However, curcumin and curcumin plus nicotine administration substantially increased liver weight and decreased the mean diameter of hepatocyte, central hepatic vein, liver enzymes, and nitric oxide levels in all groups compared with the nicotine group (p < 0.05). Curcumin demonstrated its protective effect against nicotine-induced liver toxicity.

Abstract
BACKGROUND & AIMS Smoking has been identified as a potential predisposition factor for primary biliary cirrhosis (PBC). However, it remains unclear whether it is associated with more active and severe disease. Our aim was to assess the relationships between smoking and the severity of the elementary histological lesions, as well as the biochemical and immunological features of PBC. METHODS Smoking history data were collected from 223 PBC patients using a standardized questionnaire. Histological data were available in 164 patients at presentation. Liver fibrosis and histological inflammatory activity were semi-quantified according to a METAVIR-based classification system. Odds ratios (OR) were assessed using a logistic regression analysis. RESULTS Smoking history prior to diagnosis was reported in 58 patients (26%). Twenty-five patients (11%) were active smokers at diagnosis. Male gender (OR, 4.5), alcohol intake >20 g/d (OR, 4.2), and F3-F4 fibrosis stage (OR, 2.7), but not inflammatory grade, bile duct changes, biochemical or immunological features, were associated with smoking history. Smoking intensity was significantly higher in patients with F3-F4 stage (8.1±14.2 pack-years vs. 3.0±7.0 pack-years; p=0.01). Adjusted logistic regression identified smoking history and smoking intensity as independent risk factors of advanced fibrosis. Each pack-year of increase in smoking intensity was associated with a 5.0% (95% CI, 1.3-8.7%) increased likelihood of advanced fibrosis. CONCLUSIONS Smoking increases, in a dose-dependent fashion, the risk of liver fibrosis in PBC without apparent increase in the histological inflammatory activity, bile duct lesions, biochemical, and immunological features of the disease. PBC patients should be strongly encouraged not to smoke.
