Epidemiological studies support the important role of diet in prevention and improvement of AD. In Traditional Persian Medicine (TPM), there is multiple dietary guidelines to prevent and alleviate dementia and memory impairment. Pharmacological studies have been shown that most of the TPM-recommended dietary items can improve memory and cognitive decline and possess anti-amyloidogenic, etc. activities. Among them, garlic (Allium sativum) and its compounds, S-allyl-cysteine and diallyl-disulfide, coconut (Cocos nucifera) oil, saffron (Crocus sativus) and crocin and crocetin, honey, fish, lemon balm (Melissa officinalis) and its major compounds rosmarinic acid, raisin and resveratrol, rose flowers (Rosa damascna) and geraniol, ginger (Zingiber officinale) and its 6‐gingerol and 6-shogaol, cumin (Cuminum cyminum) and its main component cuminaldehyde have been found to possess stronger anti-AD activities. Most of these items exhibited antioxidant and AChE inhibitory activities and decreased lipid peroxidation. They also possessed anti-amyloidogenic effects, reduced cerebral plaques and Aβ-species, suppressed cerebral inflammation and alterations in tau protein and inhibited Aβ-induced apoptosis through various mechanisms. Noticeably, there are similarities between TPM anti-AD diet and the typical Mediterranean diet whose beneficial effects on AD have been widely demonstrated. Given the importance of traditional medicine systems in discovering new medicines and nutraceuticals for curing ailments, considering TPM anti-AD dietary recommendations in future research would be helpful.}, keywords = {Alzheimer’s disease,Dementia,Natural products,Saffron,Traditional Persian Medicine}, url = {https://ijbms.mums.ac.ir/article_13789.html}, eprint = {https://ijbms.mums.ac.ir/article_13789_601e266ac57573499fd34835965ebd02.pdf} } @article { author = {Rezaee, Parastoo and kasra kermanshahi, Rouha and Falsafi, Tahereh}, title = {Antibacterial activity of lactobacilli probiotics on clinical strains of Helicobacter pylori}, journal = {Iranian Journal of Basic Medical Sciences}, volume = {22}, number = {10}, pages = {1118-1124}, year = {2019}, publisher = {Mashhad University of Medical Sciences}, issn = {2008-3866}, eissn = {2008-3874}, doi = {10.22038/ijbms.2019.33321.7953}, abstract = {Objective(s): Treatment of Helicobacter pylori infection by common drugs may be associated with several problems such as antimicrobial resistance to commonly used antibiotics and side effects of employed drugs. Therefore, exploration of non-chemical compounds which are safer than chemical ones is becoming important as an alternative therapy. The purpose of this study was to evaluate the effects of lactic acid bacteria (LAB) against clinical strains of H. pylori.Materials and Methods: Study of antibacterial effects of LAB against H. pylori strains included:  evaluation of LAB effects as well as its cell-free supernatant (CFS) to reduce the number of H. pylori, and to examine the effects of CFS to inhibit the urease activity of H. pylori. The anti-adhesion effect of LAB on adherence of H. pylori to epithelial cell line was also evaluated.Results: Evaluation of the anti H. pylori effect of LAB depended on the strain of H. pylori and Lactobacillus. However, CFS of LAB reduced significantly the growth of all H. pylori strains. Also, urease activity of H. pylori strains was inhibited by CFS of LAB demonstrating that their organic acid may have a role in this inhibition. The significant anti-adhesion effect of LAB on adherence of H. pylori was also observed.Conclusion: Presence of LAB and/or their CFS can reduce the count of H. pylori, inhibit the urease activity of H. pylori, and reduce adhesion of H. pylori to epithelial cell line.

This study was undertaken to determine the mechanisms underlying its regulation of apoptosis.  Materials and Methods: Mitofilin was knockdowned by specific short hairpin RNA (shRNA) and the stable HeLa cell clone was selected. The autophagy activity were assessed with LC3-II conversion and puncta formation by western blot and fluorescence imaging in starved and normal cultured HeLa cells. Autophagy flux was measured in the presence of NH4Cl. Wortmannin was used to inhibit autophagy. Cell viability and apoptosis were detected with cell counting kit-8 (CCK-8) and fluorescence-activated cell sorting (FACS) assay, respectively. Results: Mitofilin expression was down-regulated in starved HeLa cells. In established mitofilin stable knockdown cell lines, LC3-II conversion and puncta formation were detected, which are both hallmarks of autophagy, under both basal and starvation conditions. Mitofilin down-regulation decreased LC3-II conversion and puncta formation, which indicates that loss of mitofilin function inhibits both basal and starvation-induced autophagy activity. CCK-8 and FACS analysis confirmed mitofilin involvement in the regulation of cell survival since mitofilin down-regulation facilitated starvation-induced apoptosis in HeLa cells.

Tubulin polymerization test was done by using a commercial kit (Tubulin Polymerization Assay Kit).Results: In general, the cytotoxicity activities were highly dependent on the aromatic substitution pattern of phenyl ring at β position of β-acetamidoketones. Based upon, compound 4f possessing the same structural elements of colchicine and chalcone 1, revealed the most cytotoxicity more than the other β-acetamidoketone against the cancerous cell lines and showed moderate antitubulin effect. The tubulin inhibitory effect of 4f, colchicine and chalcone 1 were consistent with their antiproliferative activities. Molecular docking studies of 4f, into the colchicine-binding site of tubulin exhibited possible mode of interaction between this compound and tubulin.Conclusion: The structure activity relationship (SAR) data attained showed that the presence of trimethoxy phenyl attached to carbonyl group of β-acetamidoketones and a methoxy group at para position of the other ring are essential for cytotoxic activity.

Materials and Methods: The expression of ANGPTL8 was conducted in the pET-21b-E. coli Bl21 (DE3) system and the produced peptide was purified.

In this study, we hypothesized that the combination of idarubicin-bromelain could make cancer cells more susceptible to cytotoxicity and genotoxicity.Materials and Methods: To test our hypothesis, the optimal concentrations of idarubicin and bromelain were combined and incubated in the HL-60 cancer cell line and normal human mononuclear leukocytes (PBMC) for 24, 48, and 72 hr. Cytotoxicity and genotoxicity were evaluated by measurement of ATP cell viability test, DNA damage, Caspase-3, Acridine orange/ethidium bromide (AO/EB), and DAPI fluorescent dyes in both cell types.Results: The combination of idarubicin-bromelain significantly reduced cell proliferation in the more potent HL-60 compared to PBMC in all incubation times (P<0.05).

Real-time PCR and Western blotting were used to measure transcription of vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), platelet derived growth factor (PDGF), hypoxia inducible factor-1α (HIF-1α) and endothelial nitric oxide synthase (eNOS) and protein expression of VEGF, VEGF receptor (VEGFR) and PDGF, PDGF receptor (PDGFR), respectively. Angiogenesis and morphological changes in adductor muscles were observed.Results: Hydrogen sulfide significantly increased transcription of VEGF, EGF, PDGF, HIF-1α, eNOS and protein expression of VEGF, PDGF, and phosphorylated VEGFR and PDGFR. Treatment with hydrogen sulfide significantly improved ischemic wound healing and formation of granulation tissue, and increased the number of small vessels in the ischemic adductor muscles.Conclusion: Our data suggested that hydrogen sulfide attenuated injury of ischemic adductor muscle, and promoted the ischemic diabetic wound healing via modulating angiogenesis in type 2 diabetic db/db mice.}, keywords = {Adductor muscle,Angiogenesis,db/db mice,Diabetes,Hydrogen sulfide,Ischemia}, url = {https://ijbms.mums.ac.ir/article_13307.html}, eprint = {https://ijbms.mums.ac.ir/article_13307_71998b513dc2394fe812426e7c3bc308.pdf} } @article { author = {Hosseini, sareh and chamani, jamshidkhan and Sinichi, Mohadeseh and Bonakdar, Amir Mohammad and Azad, Zeinolabedin and Ahangari, Najmeh and Rahimi, Hamid Reza}, title = {The effect of nanomicelle curcumin, sorafenib, and combination of the two on the cyclin D1 gene expression of the hepatocellular carcinoma cell line (HUH7)}, journal = {Iranian Journal of Basic Medical Sciences}, volume = {22}, number = {10}, pages = {1198-1202}, year = {2019}, publisher = {Mashhad University of Medical Sciences}, issn = {2008-3866}, eissn = {2008-3874}, doi = {10.22038/ijbms.2019.35808.8530}, abstract = {Objective(s): Hepatocellular carcinoma (HCC) is one of the most significant health condition around the world. As the only curative therapies, liver transplantation and surgical resection are the clinical treatments of HCC. Due to the systemic toxicity and severe side effects of these treatments, it is vital to establish new therapeutic approaches. The present study aimed to compare cyclin D1 (CCN D1) gene expression in hepatocellular carcinoma cell line (HUH7) when it is treated with nanomicelle curcumin and sorafenib. The purpose was to identify toxicity risk and antioxidant activity of these drugs.Materials and Methods: The toxic dose (IC50) of nanomicelle curcumin and sorafenib were detected after treatment of HUH7 cell lines with different dose of mentioned agents followed by MTT assay. CCN D1 gene expression was evaluated using real-time PCR. Following the Tukey’s multiple comparison tests, statistical analysis is done through Student’s t-test or ANOVA.Results: The expression of the CCN D1 gene was statistically significant (P<0.001) at 289.31, 128 and 152.36 for sorafenib, nanomicelle curcumin and SNC (sorafenib-nanomicelle curcumin) respectively. The finding of this study revealed that, in comparison to sorafenib alone, the treatment of HUH7 with a nanomicelle curcumin IC50 dose, in combination with sorafenib, might down-regulate CCN D1 gene expression.Conclusion: The present research indicates that the treatment of the cell line with only nanomicelle curcumin results in the down-regulation of cyclin D1. To further decrease cyclin D1 expression, the co-delivery of curcumin and sorafenib appears to induce the apoptotic process. As a result, the effect of sorafenib cytotoxicity and CCN D1 gene expression decreases twofold.}, keywords = {Cyclin D1 Gene,Curcumin,Hepatocellular carcinoma,Nanomicelle,Sorafenib}, url = {https://ijbms.mums.ac.ir/article_13790.html}, eprint = {https://ijbms.mums.ac.ir/article_13790_704462829d667bb3c859ba7e83ca3f10.pdf} } @article { author = {Rabiei, Sana and Rezaie, Masoud and Abasian, Zahra and Khezri, Mohammad and Nikoo, Mehdi and Rafieian-kopaei, Mahmoud and Anjomshoaa, Maryam}, title = {The protective effect of Liza klunzingeri protein hydrolysate on carbon tetrachloride-induced oxidative stress and toxicity in male rats}, journal = {Iranian Journal of Basic Medical Sciences}, volume = {22}, number = {10}, pages = {1203-1210}, year = {2019}, publisher = {Mashhad University of Medical Sciences}, issn = {2008-3866}, eissn = {2008-3874}, doi = {10.22038/ijbms.2019.33201.7927}, abstract = {Objective(s): Today, consumers are looking for food products providing health benefits in addition to meeting the basic nutritional needs of the body.

The dose for ethanol was 6 ml/kg bodyweight for the first two experimental weeks, and then increased to 8, 10, and 12 ml/kg bodyweight every two experimental weeks. Alterations in the hepatic transcriptome due to concomitant administration of EECP were investigated using RNA-Seq technique.Results: Our results showed that the main EECP-responsive genes were involved in lipid syntheses, which were significantly down-regulated in both female and male mice co-administrated with EECP. In female mice, these differentially expressed genes (DEGs) were mainly associated with fatty acid biosynthesis. While in male mice, these DEGs were mainly involved in the steroid metabolic process and cholesterol biosynthetic process. Despite the sex-associated responses in lipid metabolism, EECP also exerted other beneficial effects in female mice through modulation of the cytokine-cytokine receptor interaction pathway that helped explaining its hepato-protective effectiveness.Conclusion: Our findings indicated that the mechanism regarding the hepato-protective effects of EECP was gender-dependent, which is worthy of further investigation during the development of therapeutic interventions using EECP to reduce the adverse influences of ethanol.}, keywords = {Alcoholic,Chinese propolis,Fatty liver,Inbred C57BL,Lipid metabolism,Mice}, url = {https://ijbms.mums.ac.ir/article_13794.html}, eprint = {https://ijbms.mums.ac.ir/article_13794_30bfddfbab6e4b61eef7f5ff04322719.pdf} } @article { author = {Sari, Dwi Cahyani Ratna and Arfian, Nur and Tranggono, Untung and Setyaningsih, Wiwit Ananda and Romi, Muhammad Mansyur and Emoto, Noriaki}, title = {Centella asiatica (Gotu kola) ethanol extract up-regulates hippocampal brain-derived neurotrophic factor (BDNF), tyrosine kinase B (TrkB) and extracellular signal-regulated protein kinase 1/2 (ERK1/2) signaling in chronic electrical stress model in rats}, journal = {Iranian Journal of Basic Medical Sciences}, volume = {22}, number = {10}, pages = {1218-1224}, year = {2019}, publisher = {Mashhad University of Medical Sciences}, issn = {2008-3866}, eissn = {2008-3874}, doi = {10.22038/ijbms.2019.29012.7002}, abstract = {Objective(s): Impairment of hippocampus function as a center for memory processing occurs due to stress. Centella asiatica L. (Gotu kola) is known to improve memory, intelligence, and neural protection although the precise mechanism is not well understood. This study aimed to investigate the effects of ethanol extracts of C. asiatica toward MAPK expression as down-stream signaling of brain-derived neurotrophic factor (BDNF). Materials and Methods: We performed a chronic electrical stress model on 20 male Sprague Dawley rats (2 months-old, 180–200 g). Rats were divided into four groups: normal control group (Control) which received distilled water, and three treatment groups receiving oral Gotu kola ethanol extracts in oral doses of 150 mg/kg BW (CeA150), 300 mg/kg BW (CeA300), and 600 mg/kg BW (CeA600) over four weeks. Memory acquisition was assessed with Morris water maze. Hippocampus was harvested, then extracted for protein and RNA analysis. MAPK proteins (p38, ERK1/2, JNK) were measured using Western blot, meanwhile, BDNF and TrkB receptor were analyzed with real-time PCR (RT-PCR). Results: CeA600 group revealed improvement of memory performance as shown by reduction in time and distance parameters compared to control during escape latency test. This finding associated with significant elevation of hippocampal BDNF protein and mRNA level with up-regulation of TrkB mRNA expression in CeA600 group compared to control. Western-blot analysis showed significant up-regulation of ERK1/2 protein level in CeA600 group (P<0.05) compare to control.
