Objective: Endometriosis, as a common inflammatory chronic disease is characterized by endometrial tissue growth outside the uterine cavity. It was reported that lipopolysaccharides (LPS) activate a transcription factor called LPSinduced tumor necrosis factor-alpha (LITAF) in macrophages, which induced transcription of cytokine genes such as tumor necrosis factor alpha (TNF-α). B-cell lymphoma 6 protein (BCL6) is a transcription factor which expression was increased in endometrial tissues of infertile women with endometriosis. In addition, it was shown that mRNA and protein of LITAF and BCL6 were inversely related in mature B lymphocytes and B-Cell lymphomas. Accordingly, we investigated gene expression of LITAF, BCL6 and TNF-α in eutopic and ectopic endometrial tissues of women with endometriosis compared to the controls. Materials and Methods: In this case-control study, 10 women with endometriosis (endometriosis group) and 10 women without endometriosis (control group) enrolled after diagnostic laparoscopy. Real-time polymerase chain reaction (PCR) technique was used to quantitatively analyze gene expression. One-Way ANOVA was used for data analysis. Results: This study showed that LITAF gene expression was significantly higher in ectopic endometrial tissues compared to the control samples. Expression level of BCL6 gene was significantly increased in the ectopic tissues of women with endometriosis compared to the control and eutopic samples. Although TNF-ɑ gene expression was increased in the ectopic lesions compared to the eutopic and control endometrial samples, these differences were not significant. Conclusion: The results suggested that over-expression of these inflammatory genes in ectopic endometrial lesions can be considered as a molecular scenario in pathophysiology of endometriosis by induction of inflammatory cascades and cellular proliferation.

Objective: Ovarian hyperstimulation syndrome (OHSS) is one female reproductive disorder that can occur after administration of injectable hormonal drugs to stimulate ovulation. Betaine (BET) is an intracellular biomolecule with anti-inflammatory and tissue protective effects. There is no information about its effects in an experimental model of OHSS. The current study aims to investigate the possible effects of BET on abnormal expressions of vasoconstrictor proteins and ovarian histological changes in an experimental OHSS rat model. Materials and Methods: In this experimental study, 30 adult female rats (two months old) were randomly divided into six groups (n=5 per group): i. Control, ii. OHSS [10 IU sc equine chorionic gonadotropin (eCG) for 4 days followed by 30 IU sc human chorionic gonadotropin (hCG) on the fifth day], iii. OHSS+BET (200 mg/kg/day, orally for seven days), iv. OHSS+Cabergoline (CAB, 100 mg/kg/day, orally for six days), v. BET, and vi. CAB. Expression levels of vascular endothelial growth factor (VEGF), cyclooxygenase-2 (COX-2), and blood levels of oestradiol (E2) and progesterone (P4) were measured at the end of the experiment. The ovaries were studied for histomorphological changes. Results: Induction of OHSS altered tissue histology, including an increase in the number of corpora lutea and atretic follicles, and decreased the number of follicular reserves. In this group, we observed increased expressions of the VEGF and COX-2 proteins, and increased serum E2 and P4 levels. Administration of CAB and BET significantly attenuated all molecular and histological alterations observed in the OHSS animals. Conclusion: Our findings, for first time, indicate the beneficial effects of BET to reduce OHSS complications in patients by reducing the expressions of vasoactive proteins and improving changes to the ovarian tissues. The findings are similar to CAB and can be a new avenue for future research on BET.

Objective: Multiple sclerosis (MS) has a multi-factorial etiology involving genetic factors. Fingolimod (Gilenya ®, FTY720) modulates the G-protein-coupled sphingosine 1-phosphate (S1P) receptors, S1PR1, 2, 3, 4 and 5. Variation in the human S1PR1 coding sequence results in heterogeneity in the function of the receptor. Interleukin-17, producing CD4+ T cells, tends to be increased after treatment with Fingolimod. The aim of the study was to investigate singlenucleotide polymorphisms (SNPs) in the S1PR1 gene or interleukin-17 (IL-17) levels in a small group of Iranian relapsing-remitting MS patients treated with Fingolimod. Materials and Methods: In this case-control study, the genomic DNA of 94 MS patients treated with Fingolimod was extracted and Sanger sequencing was performed on polymerase chain reaction (PCR) products to detect variants in the S1PR1 gene. Quantification of IL-17 from the serum of the patients was performed using a commercially available enzyme-linked immunosorbent assay (ELISA). Results: Among 94 relapsing-remitting MS patients treated with Fingolimod, 69 (73.4%) were responders and 25 (26.6%) were non-responders. There were four novel and five common SNPs in the S1PR1 gene and no significant association between SNP genotype and drug response was detected. In a subset of 34 patients, there was no significant difference in IL-17 serum concentrations before or after treatment and no association with S1PR1 polymorphisms was determined. Conclusion: This study is the first in Iran to investigate association between SNPs of the S1PR1 gene or IL-17 levels with fingolimod response in a small group of Iranian relapsing remitting MS patients. There was no association with S1PR1 gene SNPs or IL-17 levels before or after treatment.

Objective: Celiac disease is a common chronic inflammatory condition of the small intestine caused by permanent intolerance to gluten/gliadin. It has been demonstrated that oxidative stress is one of the mechanisms that is involved in gliadin toxicity, and there is a correlation between oxidative damage with this disease. Similarly, increased oxidative stress was repeatedly reported in infertile men which led to low-quality of sperm function. Therefore, we aimed to assess sperm parameters and chromatin status in men with Celiac disease. Materials and Methods: In this case-control study, semen samples were collected from 11 fertile men without Celiac and 10 men with diagnostic Celiac disease. Basic semen analyses were performed according to the World Health Organization (WHO) 2010 protocol. The percentage of sperm with persistence histones, protamine deficiency, DNA fragmentation, malondialdehyde (MDA), and intracellular reactive oxygen species (ROS) were assessed using aniline blue, chromomycin A3, sperm chromatin structure assay, thiobarbituric acid reactive substances (TBARS) assay, and diacetyldichlorofluorescein staining, respectively. Results: Unlike the sperm parameters, which did not show significant differences between men with Celiac disease and fertile individuals, sperm chromatin maturation (persistence histones and protamine deficiency) and sperm DNA damage in men with Celiac disease were significantly higher compared to fertile individuals (P<0.05). In addition, the percentage of sperm viability in these individuals was significantly lower than that in the fertile individuals (P<0.05). We did not observe any significant differences in sperm lipid peroxidation and intracellular ROS levels between the two study groups (P>0.05). Conclusion: Celiac disease affects sperm chromatin maturation and DNA fragmentation, emphasizing its impact on reproductive health.

Kidney-liver crosstalk plays a crucial role in normal and certain pathological conditions. In pathologic states, both renal-induced liver damage and liver-induced kidney diseases may happen through these kidney-liver interactions. This bidirectional crosstalk takes place through the systemic conditions that mutually influence both the liver and kidneys. Ischemia and reperfusion, cytokine release and pro-inflammatory signaling pathways, metabolic acidosis, oxidative stress, and altered enzyme activity and metabolic pathways establish the base of this interaction between the kidneys and liver. In these concomitant kidney-liver diseases, the survival rates strongly correlate with early intervention and treatment of organ dysfunction. Proper care of a nephrologist and hepatologist and the identification of pathological conditions using biomarkers at early stages are necessary to prevent the complications induced by this complex and potentially vicious cycle. Therefore, understanding the characteristics of this crosstalk is essential for better management. In this review, we discussed the available literature concerning the detrimental effects of kidney failure on liver functions and liver-induced kidney diseases.

Objective: Enhanced cell survival and drug resistance in tumor cells have been linked to the overexpression of antiapoptotic members of the Bcl-2 family proteins, including Bcl-2 and Mcl-1. The aim of this study was to explore the impact of formononetin and dihydroartemisinin combination on the growth and apoptosis of acute myeloid leukemia (AML) cells. Materials and Methods: In this experimental study, the cell survival and cell proliferation were tested by MTT assay and trypan blue staining. The evaluation of cell apoptosis was conducted using Hoechst 33342 staining and a colorimetric assay to measure caspase-3 activity. To determine the mRNA levels of Mcl-1, Bcl-2, Bax, and Cyclin D1, a quantitative real-time polymerase chain reaction (qRT-PCR) was performed. Results: We showed that treatment with either formononetin or dihydroartemisinin alone, led to significant decrease in the cell survival and growth, and triggered apoptosis in U937 and KG-1 AML cell lines. Moreover, treatment with each of the compounds alone significantly decreased the mRNA levels of Mcl-1, Bcl-2 and Cyclin D1 mRNA, while, the expression level of Bax mRNA was enhanced. Combination of two compounds showed a synergistic anti-cancer effect. Conclusion: The anti-leukemic potential of formononetin and dihydroartemisinin is exerted through the effect on cell cycle progression and intrinsic pathway of apoptosis. Therefore, they can be considered as a potential anti-leukemic agent alone or along with existing chemotherapeutic drugs.

Objective: Acute lymphoblastic leukemia (ALL) is a highly heterogeneous leukemia. Despite the current improvement in conventional chemotherapy and high survival rates, the outcomes remain challenging. Sesquiterpen extracted from the Tanacetum parthenium, parthenolide, is a potential anticancer agent that can modulate the expression of miRNAs and induce apoptosis. The objective of this study was to investigate the effect of parthenolide in combination with vincristine and alone on the apoptosis rate and expression of miR-125b-5p, miR-181b-5p, and miR-17-5p in the NALM6 cell line. Materials and Methods: In this experimental study, cell viability and metabolic activity were determined through MTT assay and PI staining. Flow cytometry was applied to evaluate the rate of apoptosis. The expression of miRNAs was assessed using real-time polymerase chain reaction. Bioinformatic analyses, including Cytoscape, RNAhybrid, and signaling pathway analysis were employed to investigate the association of miR-17-5p, miR-181b-5p and miR-125b- 5p with apoptosis. Further, molecular docking served to validate the modulation of these miRNAs by parthenolide and vincristine treatment. Results: The MTT assay indicated that 7.7 μM of parthenolide decreased the metabolic activity to 50% after 48 hours. PI staining analysis indicated that at concentrations below the half maximal inhibitory concentration, parthenolide caused 50% cell death. Flow cytometric analysis indicated that parthenolide (1.925 μM) in combination with vincristine (1.2 nM) induced apoptosis in 83.2% of the cells. Real-time quantitative reverse transcription polymerase chain reaction (qRTPCR) analysis showed significant changes in the expression levels of miR-17-5p, miR-125b-5p, and miR-181b-5p. Moreover, the combination therapy downregulated the expression of miRNAs significantly. This was consistent with our bioinformatic analysis demonstrating that the studied miRNAs are regulators of apoptosis. Finally, molecular docking validated the modulation of the miRNAs by parthenolide and vincristine. Conclusion: Parthenolide in combination with vincristine triggers apoptosis at a high rate in the NALM6 cell line. Moreover, this combination therapy can decrease the expression of miR-17-5p, miR-181b-5p, and miR-125b-5p.

Objective: According to the response-to-retention hypothesis, the inception of atherosclerosis is attributed to the deposition and retention of lipoprotein in the arterial intima, facilitated by altered proteoglycans with hyperelongated glycosaminoglycan (GAG) chains. Recent studies have elucidated a signaling pathway whereby transforming growth factor-β (TGF-β) promotes the expression of genes linked to proteoglycan GAG chain elongation (CHSY1 and CHST11) via reactive oxygen species (ROS) and the downstream phosphorylation of ERK1/2 and Smad2L. Atorvastatin is known to exhibit pleiotropic effects, including antioxidant and anti-inflammatory. The purpose of the present research was to ascertain the influence of atorvastatin on TGF-β-stimulated expression of CHST11 and CHSY1 and associated signaling pathways using an in vitro model. Materials and Methods: In this experimental study, vascular smooth muscle cells (VSMCs) were pre-incubated with atorvastatin (0.1-10 μM) prior to being stimulated with TGF-β (2 ng/ml). The experiment aimed to evaluate the phosphorylation levels of Smad2C, Smad2L, ERK1/2, the NOX p47phox subunit, ROS production, and the mRNA expression of CHST11 and CHSY1. Results: Our research results indicated that atorvastatin inhibited TGF-β-stimulated CHSY1 and CHST11 mRNA expression. Further experiments showed that atorvastatin diminished TGF-β-stimulated ROS production and weakened TGF-β-stimulated phosphorylation of p47phox, ERK1/2, and Smad2L; however, we observed no effect on the TGF-β- Smad2C pathway. Conclusion: These data suggest that atorvastatin demonstrates anti-atherogenic properties through the modulation of the ROS-ERK1/2-Smad2L signaling pathway. This provides valuable insight into the potential mechanisms by which atorvastatin exerts its pleiotropic effects against atherosclerosis.

Objective: This paper aimed to investigate the PI3K/Akt/mTOR signal-pathway regulator factor-related lncRNA signatures (PAM-SRFLncSigs), associated with regulators of the indicated signaling pathway in patients with lung adenocarcinoma (LUAD) undergoing immunotherapy. Materials and Methods: In this retrospective study, we employed univariate Cox, multivariate Cox, and least absolute shrinkage and selection operator (LASSO) regression analyses to identify prognostically relevant long non-coding RNAs (lncRNAs), construct prognostic models, and perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. Subsequently, immunoassay and chemotherapy drug screening were conducted. Finally, the prognostic model was validated using the Imvigor210 cohort, and tumor stem cells were analyzed. Results: We identified seven prognosis-related lncRNAs (AC084757.3, AC010999.2, LINC02802, AC026979.2, AC024896.1, LINC00941 and LINC01312). We also developed prognostic models to predict survival in patients with LUAD. KEGG enrichment analysis confirmed association of LUAD with the PI3K/Akt/mTOR signaling pathway. In the analysis of immune function pathways, we discovered three good prognostic pathways (Cytolytic_activity, Inflammation-promoting, T_cell_co-inhibition) in LUAD. Additionally, we screened 73 oncology chemotherapy drugs using the "pRRophetic" algorithm. Conclusion: Identification of seven lncRNAs linked to regulators of the PI3K/Akt/mTOR signaling pathway provided valuable insights into predicting the prognosis of LUAD, understanding the immune microenvironment and optimizing immunotherapy strategies.

Objective: Danon disease is defined by a clinical trio of cardiomyopathy, skeletal myopathy, and cognitive impairment. It results from the lysosomal-associated membrane protein-2 (LAMP2) gene variants. The aim of study is determination of genotype and phenotype of a newly diagnosed Iranian family with a unique phenotype due to a pathogenic variant of the LAMP2 gene along with a phenotypic comparison of all reported patients. Materials and Methods: In this descriptive study, we evaluated the demographic data, clinical features, management procedures, as well as genetic analysis of both patients in this newly diagnosed family. Whole genome sequencing (WGS) and in silico structural and functional predictions were applied. A comprehensive search of the c.877C>T variant in LAMP2 was conducted using the PubMed, Google Scholar, VarSome, ClinVar, Human Gene Mutation Database (HGMD), and Franklin databases to identify any genotype-phenotype correlations. Results: Nine patients were carriers of the c.877C>T variant. All patients were male, and displayed variable degrees of left ventricular hypertrophy (LVH) that ranged from mild to severe. All patients exhibited typical cardiac conduction abnormalities consistent with Danon disease. Four underwent heart transplants and survived. Skeletal muscle involvement and cognitive impairment were observed in four patients each. The mean age of onset was 14 years. The proband in this study exhibited an earlier onset of cardiac symptoms. Conclusion: Genetic analysis is the preferred diagnosis approach for Danon disease and can assist families in managing affected patients, identify carriers, and assist with future family planning. This study highlights the intrafamilial phenotypic variability of Danon disease. It is possible that variants of this gene may be frequent in Iran.

Objective: Reduction of cerebral ischemia-reperfusion injury (IRI)/re-oxygenation injury, is defined as the paradoxical exacerbation of the cellular dysfunction and death, following restoration of the blood flow to previously ischemic tissues. The re-establishment of blood flow is essential to salvage the ischemic tissues. As a result, the treatment of IRI with novel therapies, which have fewer side effects, are of great importance. Therefore, this study aimed to investigate the effects of curcumin nanoparticle (CN) pre-treatment on the cerebral I/R rat model. Materials and Methods: In this experimental study, CN was administered to rats orally five days before the bilateral common carotid artery occlusion (BCCAO) and continued for three days. The intensity of oxidative stress, the activities of antioxidant enzymes, glutathione (GSH) content, the activity of mitochondrial enzymes, including succinate dehydrogenase (SDH), malate dehydrogenase (MDH) and lactate dehydrogenase (LDH), curcumin bioavailability, pERK/ERK expression ratio and TFEB protein were studied. Data analysis was performed using Graphpad Prism V.8 software, one-way analysis of variance (ANOVA) with the statistical package for the social sciences (SPSS V.26 software). Results: Cerebral IRI-damage significantly increased the oxidative stress (P=0.0008) and decreased the activity of the antioxidant enzymes including catalase (CAT) (P<0.001), super oxide dismutase (SOD) (P<0.001), reduced GSH (P<0.001), mitochondrial enzymes, pERK/ERK expression ratio (P=0.002) and TEFB protein (P=0.005) in rats’ brains. In addition, the pre-treatment of the rats with CN resulted in a decrease in the reactive oxygen species (ROS), and an increase in the activities of antioxidants and mitochondrial enzymes. This in turn up-regulated the pERK/ERK expression ratio and TEFB expression. Conclusion: CN has neuroprotective effects on the cerebral IRI condition due to its antioxidant properties and is able to overexpress the pERK and TFEB proteins; thus, it can be considered as a suitable treatment option during and after the incidence of stroke.

Objective: Diabetic men suffer an increased risk of infertility associated with signs of oxidative damage and decreased methylation in sperm pointing to a deficit of the one-carbon cycle (1CC). We aimed to investigate this deficit using mice models (type 1 and 2) of streptozotocin-induced diabetes. Materials and Methods: In this experimental study, 50 male mice, aged eight weeks, were divided randomly into four groups: sham, control, type 1 diabetes mellitus (DM1), and DM2. The DM1 group was fed a normal diet (ND) for eight weeks, followed by five consecutive days of intraperitoneal administration of Streptozotocin (STZ, 50 mg/kg body weight). The DM2 group was fed a high-fat diet (HFD) for eight weeks, followed by a single intraperitoneal injection of STZ (100 mg/kg). After twelve weeks, all the mice were euthanized, and study parameters assessed. In the sham group, citrate buffer as an STZ solvent was injected. Results: Both types of diabetic animals had serious impairment of spermatogenesis backed by increased DNA damage (P=0.000) and decreased chromatin methylation (percent: P=0.019; intensity: P=0.001) and maturation (P=0.000). The 1CC was deeply disturbed with increased homocysteine (P=0.000) and decreased availability of carbon units [methionine (P=0.000), serine (P=0.088), folate (P=0.016), B12 (P=0.025)] to feed methylations. Conclusion: We have observed a distinct impairment of 1CC within the testes of individuals with diabetes. We speculate that this impairment may be linked to inadequate intracellular glucose and diminished carbon unit supply associated with diabetes. As a result, interventions focusing on enhancing glucose uptake into sperm cells and providing supplementary methyl donors have the potential to improve fertility issues in diabetic patients. However, additional clinical testing is required to validate these hypotheses.
