Abstract

Background and objectives: Endometrial tissue growth and its activity outside the uterus cause endometriosis. It has been suggested that various epigenetic deviations play a major role in the pathogenesis of endometriosis. Steroidogenic factor 1 (SF-1; NR5A1) is an essential transcription factor for estrogen biosynthesis in endometrial cells. The expression of SF-1 in endometriosis and lack of expression in normal endometrium is primarily determined by its promoter methylation. Here, we aimed to compare the methylation status of the SF-1 gene promoter region in women with endometriosis in comparison to healthy subjects.
Methods: In the present case–control study, DNA was extracted from 25 endometrial tissue samples from women with endometriosis and 5 normal post-hysterectomy endometrium tissues which were collected from Tabriz hospitals including Vali-e-Asr, Taleghani, 29 Bahman and Shams in 2016. The obtained DNA samples were subjected to Bisulfite-treatment. Finally, the status of SF-1gene promoter methylation was evaluated by methylation specific PCR method. Statistical analyses including descriptive and inferential statistics were conducted using tables, bar charts by statistical software SPSS version 20 and independence test.
Results: The methylation status of SF-1 gene promoter was decreased significantly in endometriosis samples (P<0.05).  
Conclusion: SF-1 gene promoter hypomethylation could increase the relative expression of SF-1 gene in endometriosis which may lead to the development or progression of the disease.

Abstract

Background and objectives: Rheumatoid arthritis (RA) is a complex and systemic inflammatory disease in which the immune response is disturbed. Single nucleotide polymorphisms (SNPs) in the promoter regions of regulatory cytokines including interleukin-10 (IL-10) may lead to exacerbated immune response and increased risk of RA. Here, we aimed to assess the association of IL-10 -1082 (G/A) (rs1800896) promoter polymorphism with the susceptibility to RA in a population in northeast of Iran.
Methods: A total of 130 RA patients and 128 sex- and age- matched healthy donors were enrolled. The polymerase chain reaction (PCR) was used to amplify the polymorphic regions and restriction fragment length polymorphism (RFLP) technique was applied to detect rs1800896. SPSS 22.0 software was used to analyze data statistically.
Results: Our findings revealed that G allele was significantly associated with the increased risk of RA [OR = 1.88, 95% CI (1.32–2.66), P-value = 0.0001] in patients. Setting AA genotype as the reference, the AG [OR = 2.93, 95% CI (1.68–5.12), P-value = 0.0001] and GG [OR = 5.73, 95% CI (2.30–14.23), P-value = 0.0001] genotypes were significantly associated with RA susceptibility.
Conclusion: The present study suggests that the IL-10 -1082 (G/A) genetic variants are associated with RA susceptibility, but not with the disease activity. While this is the first time to report such an association in a population in northeast of Iran, further studies are needed to confirm these findings.

Abstract

Background and objectives: Rheumatoid arthritis (RA) is an autoimmune disease with a complex genetic background. The protein tyrosine phosphatase non-receptor type 22 (PTPN22) is a lymphoid specific protein tyrosine phosphatase which is involved in negative regulation of T cell response. Several studies have assessed the association between PTPN22 single nucleotide polymorphisms (SNPs) with RA susceptibility. Here, we aimed to assess the association of PTPN22 (1858 C>T) variant with the susceptibility to RA in northeast of Iran.
Methods: A total of 127 RA patients and 119 age- and sex- matched healthy donors were enrolled. The polymerase chain reaction (PCR) followed by restriction fragment length polymorphism (RFLP) technique (PCR-RFLP) was applied to detect PTPN22 (1858 C>T) SNP. SPSS 22.0 software was used to analyze data using relevant statistical tests.
Results: Comparison of allele and genotype frequencies of PTPN22 (1858 C>T) SNP in RA patients and healthy donors revealed no significant association with RA susceptibility.
Conclusion: The present study suggests that the PTPN22 (1858 C>T) genetic variants are not associated with RA susceptibility and disease activity. While this is the first report from northeast of Iran, further studies are needed to confirm these findings

Abstract

Background: Disorders of sex development (DSD) are a medical condition that affects the normal process of sexual  Various of the genes needed for gonad development have been identified by investigation of patients with disorders sex development (DSD).Phenotypes of patients with 46,XY DSD range from atonalism in female phenotype with complete external  genitalia to male phenotype with testicular regression. Individuals with 46,XYagonadiam show a wide range of clinical features and in some cases, there is not a clear diagnosis for this patients. We presented the clinical and molecular study a patient with 46,XY female without gonadal tissue.
Case presentation: A 27-year-old female was attended to our center because of primary amenorrhea. Ultrasonography did not show gonadal tissue including Mullerian structures, uterus, and Wolffian structures. Also, the patient had not streak gonad. We performed cytogenetic study and molecular analysis, including automated sequencing of the entire coding region of SRY gene, in the patient with agonadism. Our result showed 46,XY karyotype. Also, we noticed that molecular mutations in SRY are not identified as a cause of DSD female without a gonadal tissue. Laboratory examination showed that this case is a unique patient with 46,XYfemale agonadism that has no association with previously described.
Conclusions: The present case was a patient with 46, XYagonadism without hormonal or kidney defect and we did not detect mutation in SRY gene. To our knowledge, this case is a unique patient with 46,XYagonadism that has no association with previously described. So this case would be helpful for clinicians to assess 46,XY female patients without gonadal tissue.

Abstract

Infertility is defind as the inability to conceive after one year of regular unprotected sexual intercourse by a couple. Female infertility can have different causes that all factors can in somehow be influenced by genetic factors. Studies have shown that epigenetic changes play an important role in fetal development, oogenesis and spermatogenesis. During the growth of oocyte, follicular cells make a multilayer coating of granulosa cells. Granulosa cells are affected by gonadotropin hormones. The CYP11A1 gene is one of the genes involved in the production of steroid hormones in luteinized granulosa cells. The CYP11A1 enzyme in the progesterone prodaction path way leads to the conversion of cholesterol to pregnenolon. Progesterone is an important steroid hormone that plays an important role in fertility and pregnancy. Histone modifications help to express the CYP11A1 gene. Trimethylation of Lysine 4 on histone H3 (H3K4me3) works to active transcription in the CYP11A1 promoterIn the present study, the level of methylation H3K4me3 in regulation area of CYP11A1 gene in granulosa cells collected from the women with infertility problem and also from fertile women giving oocyte was investigated in Tabriz Jihad Daneshgahi infertilization center. To do this, the Chromatin Immunoprecipitation and then Real-Time PCR were used to investigate the level of methylation.According to the results of the present study, the level of methylation H3K4me3 in the regulating area of CYP11A1 gene in the given infertile people doesn’t show significant difference in comparision with control group and no significant relationship was observed between methylation of histone in CYP11A1 promoter and number of follicles and oocyte.It is suggested that epigenetic changes in regulating area of CYP11A1 gene are not involved in the number of follicle and oocytes.

Abstract

Infertility is a disorder of the reproductive system, which often occurs after one year of regular unprotected intercourse with the aim of pregnancy. Several physical functions require the synthesis of steroid hormones, in which gonadal steroids (estrogen and progesterone) play a pivotal role in reproduction. Follicular growth and ovulation depend on the proliferation and differentiation of the granulosa and theca cells, which are possible in the steroid pathway after stimulation with the ovarian gonadotropins and cytokines. Steroidization is initiated with the transfer of cholesterol by the StAR protein to the mitochondrial membrane of the steroid cells, which is followed by a cascade of steroid hormones. Recent studies have highlighted the impact of epigenetic mechanisms on reproduction, emphasizing the importance of these changes in the early and secondary stages of gametogenesis. To determine the causes of infertility, it is essential to recognize the altered epigenetic modifications of the relevant gene and its mechanisms. In the present study, the H3K4me3 methylation level was evaluated in the StAR gene regulatory region in the granulosa cells collected from the fertile and infertile women referring to Tabriz Jihad Infertility Centerin Tabriz, Iran using ChIP-qPCR. According to the results, the H3K4me3 methylation level increased in the StAR gene regulatory region in the fertile women compared to the infertile women. In addition, a significant correlation was observed between the follicle and egg rates at the MII stage and the level of this methylation.

Abstract

Background and objectives: Controlling nutrition and exercise can be two important strategies in controlling tendon health. It has been reported that resistance training and palm pollen separately can improve Scleraxis (Scx) in tendon tissue; so present study aimed to investigate the interactive effects of resistance training with ethanolic extract of palm pollen on Scx protein and gene expression levels in the tendon tissue of male adult rats.
Methods: In this experimental study 30 male adult rats divided into 6 groups of 6 rats including: 1) sham, 2) training, 3) palm pollen, 4) testosterone, 5) training + palm pollen, and 6) training + testosterone. During 4 weeks, groups 2, 5, and 6 performed resistance trainings for five sessions per week; groups 3 and 5 received 100 mg/kg palm pollen for five days per week via gavage and groups 4 and 6 received 2 mg/kg testosterone propionate peritoneally. Scx protein and gene expression levels were measured in tendon tissue by Western blot and real-time PCR methods respectively. Shapiro- Wilk, one way ANOVA with Tukey’s post- hoc tests were used to analyze the findings (P≤0.05).
Results: Training significantly increased Scx protein levels (P=0.005); palm pollen significantly increased Scx gene expression levels (P=0.001); training + palm pollen significantly increased Scx protein and gene expression levels (P=0.001) also training + palm pollen had more favorable effect on increase of Scx protein and gene expression levels compared to training and palm pollen alone (P=0.001).
Conclusion: It seems that resistance training simultaneously with palm pollen administration can have a more favorable effect than each one alone on improving Scx protein and gene expression levels in tendon tissue of male adult rats.

Abstract

Background and objective: Exercise and nutrition are two factors influencing the improvement of inflammatory markers in patients with colon cancer. Aim of present study was to investigate the effect of aerobic training (AT) with Purslane (Portulaca Oleracea) Seed (PS) on toll like receptor 2 (TLR-2) and TLR-4 in colon tumor tissue of rats with colon cancer.
Methods: In this experimental study 30 adults rats were divided into five groups of six rats including: 1) healthy control, 2) control, 3) training, 4) PS, and 5) training + PS. Colon cancer induced by intra-peritoneal injection of azoxymethane in groups 2- 5. During eight weeks, groups 3 and 5 performed AT for five sessions per week also groups 4 and 5 received 75 mg/kg PS intra-peritoneally. TLR2 and TLR4 protein levels were measured by ELISA method. For review the normal distribution and data Shapiro- wilk was used and for statistical analysis of data one way ANOVA with Tukey’s post- hoc tests were used (P≤0.05).
Results: Training had not significant effect on TLR-2 (P=0.91) and TLR-4 (P=0.95); PS and training + PS significantly decreased TLR-2 and TLR-4 (P=0.001) also training + PS had more favorable effect on decrease of TLR-2 compare to training and PS alone (P=0.001).
Conclusion: Although PS alone can improve TLR-2 and TLR-4 levels in colon tumor tissue of adult rats with colon cancer, nevertheless it appears that AT along with PS have more favorable effects on improvement of TLR-2 compare to training and PS alone.

Abstract

Background and Objective: Alpha-thalassemia (α-thal) appears to be the most common monogenic disorder worldwide. The diagnosis of α-thalassemia depends on the detection of Hemoglobin Bart (Hb Bart's) in newborns, which indicates one or more defective or absent α-globin genes. In addition, in patients with Hemoglobin H (Hb H), the Hb H range usually varies between 7-10 g / dL. Therefore, tracking Hb Bart's and Hb H can be useful in diagnosing thalassemia α. This study was performed to evaluate Hb Bart's and Hb H in infants with α thalassemia in Ardabil province, northwestern Iran.
Material and Methods: In this cross-sectional descriptive study, 33 infants with alpha thalassemia mutation, including infants born in Ardabil province, Iran in the years 2020 to 2019. Hemoglobin analysis was performed by capillary electrophoresis system.
Results: Hb H and Hb Bart's were detected in only two cases (6%) and three cases (9%). In this study, only 5 patients (15.15) were observable by detection of Hb Bart's and Hb H levels by electrophoresis. In cases of Hb Bart disease, -α3.7 was the most common genotype. Therefore, most infants with alpha thalassemia were lost when electrophoresis alone was used.
Conclusion: This study showed that molecular analysis of Hb Bart's newborns is necessary to confirm α-thalassemia. Capillary electrophoresis is a way to prevent the diagnosis of rare Hb H and Bart's disease.

Doxorubicin is a type of chemotherapy drug used to treat a variety of cancers. However, its side effects have limited its use. The aim of this study was to synthesize and evaluate polymer micelles containing doxorubicin and evaluate its toxicity on MCF7 breast cancer cells and HepG2 liver cancer cells.
Material and Methods: For this purpose, PBMA-b-POEGMA diblock copolymer was first synthesized using the RAFT method and confirmed by GPC. Dynamic light scattering (DLS) and Transmission electron microscope (TEM) were used to observe the morphology, size, and polydispersity of the micelles. In addition, in vitro cytotoxicity of DOX-loaded polymeric micelles against MCF7 cells and HepG2 cells were assessed. Furthermore, cell uptake and apoptosis assay of DOX-loaded polymeric micelles against MCF7 cells were evaluated.
Results: The TEM image revealed that the nanoparticles were spherical and uniform. The particle size and polydispersity measured by DLS were 35 nm and 0.13, respectively. The drug encapsulation efficiency and drug loading contents were 50±3.46 % and 4.53±0.29 %, respectively. The drug release rate was reported 69% in saline phosphate buffer (pH 7.4) within 24 hours. The results showed that micelles containing doxorubicin had a greater effect on MCF7 cell viability than the free drug. The MTT assay demonstrated that micelles were biocompatible to HepG2 cells while DOX-loaded micelles showed significant cytotoxicity. The IC50 of doxorubicin-loaded micelles against MCF7 cells were obtained to be 0.5 μg/ml. It was further shown that micelles containing doxorubicin had higher cell uptake and apoptosis than free drugs on MCF7 cells.
Conclusion: These polymeric micelles are an ideal candidate to deliver anticancer agents into breast cancer cells.

Abstract

Background and objectives: Zingiber officinale extract can control cardiovascular risk factors. Moreover, endurance training may effectively rehabilitate myocardial infarction by strengthening the myocardial muscle tissue. In-silico analysis identified essential genes involved in the heart damage process based on data from the DisGeNET database. Hence, we estimated the affinity of chemical and bioactive molecules for PPARγ. Therefore, this study aimed to investigate the effect of endurance exercise alone or combined with Zingiber officinale extract on Myocardial infarction rats.
Material and Methods: Twenty-five male rats were randomly divided into five groups, including (1) group of myocardial infarctions (MI) induced by subcutaneous injection of isoproterenol, (2) myocardial infarction+exercise (MI+EX), (3) myocardial infarction+Zingiber Officinale extraction administered orally (MI+GE), (4) myocardial infarction+exercise+Zingiber Officinale extract (MI+EX+GE), and (5) Control group. The qPCR-Real Time technique was used to measure the expression of PGC1-ɑ, PPARγ, and TNF-ɑ genes. We evaluated the concentration of Troponin-1 as a vital myocardial ischemia marker.
Results: In bioinformatics analysis, we found that the PPARγ, PGC1-ɑ, and TNF-ɑ pathways were critical in heart injury. Also, the effects of Zingiber officinale on heart tissue were detected through PPARγ by drug design. Endurance training combined with Zingiber officinale consumption reduced the expression of TNF-ɑ, Troponin-1 and increased the PGC1-ɑ, PPARγ genes. Furthermore, consumption of Zingiber officinale extraction improved the levels of PGC1-ɑ, PPARγ, TNF-ɑ, and Troponin-1.
Conclusion: Our data indicated that six weeks of endurance training and consumption of Zingiber officinale extract could reduce the relative expression of the TNF-ɑ and significantly increase the level of PGC1-ɑ, PPARγ.

Abstract

Background and Objectives: The inability of classic fluorescence-activated cell sorting to single cancer cell sorting is one of the most significant drawbacks of this method. The sorting of cancer cells in microdroplets significantly influences our ability to analyze cancer cell proteins.
Material and Methods: We adapted a developed microfluidic device as a 3D in vitro model to sorted MCF-7 cancer cells on a chip. A prefabricated microfluidic droplet chip was used in this research. Then, with the help of synthesized fluorescent probes, MCF-7 cancer cells were separated from normal cells.
Results: This research presents a modification of GQD bead for high-throughput analysis and sorting single cancer cells. We elaborate a binding assay as an example of this approach for detecting MCF-7 cancer cell lines. Graphene quantum dot-decorated mesoporous silica nanoparticles (GQD@MSNPs) act as fluorescent optical beads coated in microfluidic droplets. The fluorescent beads capture cancer cells. To enable droplet sorting at 200 Hz and cell enrichment, a measurable fluorescence signal is generated when cancer cells bind to these beads and boost the drop's fluorescence emission.
Conclusion: Herein, we report in vitro results showing that the as-prepared GQD@MSNs have exceptional luminous characteristics. The specific surface area and pore volume of GQD-MSNs were found to be 50% and 40% higher than those of pure MSNs, which is rather remarkable. Because of these improved qualities, GQD@MSNs are demonstrated a large sorting capacity that makes them ideal for diagnosis.

Abstract

Background and Objectives: Oral cancer relates to oral and intestinal microbiota composition. Lactobacillus species are considered probiotic bacteria due to their ability to modulate human immune responses and therapeutic effects. This study aimed to investigate the effects of Lactobacillus plantarum (L. plantarum) on TLR4 gene expression and its downstream pathways in a mouse model of oral cancer.
Material and Methods: This experimental study was conducted in the Stem Cell Research Center, Faculty of Modern Technologies, Golestan University of Medical Sciences, Gorgan, Iran, in 2021. L. plantarum strain ATCC 8014 was used in this study. Twenty-eight male Wistar rats were divided into four groups (n = 7). 4-Nitroquinoline 1-oxide (4NQO) was used to establish oral cancer in rats. A pathological examination was adopted to confirm cancer establishment. Rats were treated with probiotic L. plantarum before and after cancer development. After extracting RNA from blood and synthesizing cDNA, the ability of lactobacilli to modulate the expression of TLR4 genes was investigated by Real-Time PCR Methods (RT-PCR).
Results: In the present study, it was observed that after causing cancer and treating the animal with L. plantarum, the expression of the TLR4 gene decreased significantly (P-value < 0.05), which might, in turn, affect the downstream pathways, which included the decrease in the expression of BCL-2 and NF-ĸB genes. Accordingly, the expression of the NF-ĸB gene was significantly reduced in rats received L. plantarumgavaged for two weeks after cancer induction.
Conclusion: According to the obtained results, probiotic L. plantarum significantly affects the gene expression of NF-ĸB and TLR4 in cancerous rats. It was also shown that L. plantarum was more efficient in reducing TLR-4 and NF-ĸB genes expression when it was gavaged for 14 days after tumor induction.

Abstract

Background: Genetic polymorphisms are predictors of the immune response and susceptibility to certain infectious diseases, including pulmonary tuberculosis (TB). We evaluated the association of monocyte chemoattractant protein-1 (MCP1) (-2581 A/G) and interferon-gamma (IFNγ) (+874 T/A) polymorphisms with susceptibility to pulmonary TB in an Iranian population.
Methods: A total of 124 patients with pulmonary tuberculosis and 244 healthy subjects (121 related normal controls and 123 unrelated subjects) were included. The MCP1 polymorphic region (-2518 A/G) was genotyped by PCR-RFLP, while ARMS-PCR was used to amplify and detect IFNγ (+874 T/A). SNPStats and SPSS v. 20 were used for the statistical analysis of the data.
Results: The comparison of MCP1 (-2518 A/G) alleles and genotypes in TB patients and healthy subjects showed no significant association in all the constructed heredity models. No association was observed between TB patients and normal subjects in all the constructed inheritance models for IFNγ (+874 T/A) alleles and genotypes.
Conclusion: Due to the lack of association between MCP1 (-2518 A/G) and IFNγ (874 T/A) polymorphisms and susceptibility to PT in our study and the conflicting results of some previous studies, further clinical and molecular research is needed to clarify the role of the studied polymorphisms in the pathogenesis of tuberculosis.

Abstract

Background: Aerobic exercise and ginger after myocardial infarction (MI) modify calcium handling. Ginger has cardioprotective effects on cardiovascular disease. This study assessed the effects of aerobic exercise combined with ginger extract (GE) loaded into chitosan nanoparticles (CNPs) on miRNA-214, Serca2a, and Anp genes and cardiac fibrosis in myocardial infarction (MI) rat models.
Methods: Twenty-five male rats divided into 5 groups were subjected to ginger treatment and exercise. Aerobic exercises (AE) were performed on a rodent treadmill 5 days per week for 6 weeks. The GE-CNPs (500 mg/kg) were orally administered to the rats for 6 weeks. The expressions of miRNA-214, Serca2a, and Anp genes were assessed by real-time polymerase chain reaction (PCR). The histopathological assessments were performed using hematoxylin and eosin (H&E) and Masson's trichrome staining. The serum activities of creatine kinase-MB (CK-MB) and lactate dehydrogenase (LDH) were also measured by ELISA.
Results: The MI model and CNP groups had the highest rate of collagen deposition (P <0.05). The serum activities of both CK-MB and LDH were significantly elevated in the Isop group compared to the control (P<0.05), while following aerobic exercise and ginger treatment, their activity was significantly dropped in the Isop + AE + GE-CNPs group. The expression of miRNA-214 showed a significant increase in GE-CNPs (P <0.01) and GE-CNPs + AE (P <0.001) groups. Serca2a and Anp genes showed significant changes in the GE-CNPs + AE group (P<0.05).
Conclusion: Our findings revealed that aerobic exercise, along with ginger treatment, improved cardiac fibrosis, modulating the expression levels of miRNA-214, Serca2a, and Anp genes and serum levels of MI biomarkers.
