[PMID: 36855913 DOI: 10.1515/hmbci-2022-0056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Accepted: 02/11/2023] [Indexed: 03/02/2023]
Abstract
OBJECTIVES Type 2 diabetic Mellitus (T2DM) is the most common systemic and endocrine disease in humans, and diabetic nephropathy is one of the most serious complications of this disorder. The polymorphisms in the apolipoprotein A5 (ApoA5) gene are strongly related to hypertriglyceridemia and are considered a predisposing factor for diabetic nephropathy. The current study proposed to examine the association of APOA5-S19W polymorphism with serum lipids levels in patients with type 2 diabetic nephropathy in Mazandaran province. METHODS This case-control study was designed to determine the association of APOA5-S19W polymorphism with plasma lipid profile in 161 T2DM patients with nephropathy (DN+), without nephropathy (DN-), and in 58 healthy individuals. Lipid profile values were measured using Pars Azmoun commercial kits. S19W variant, one of the polymorphisms of the APOA5 gene, was determined by PCR-restriction fragment length polymorphism (PCR-RFLP) and Taq1 restriction enzyme. RESULTS In comparison between the three groups, DN+ had a higher mean TG than DN- and the control group (p<0.001). The incidence of the G allele in DN+ was not significant compared to groups of DN-. Comparing the relationship between the mean of biochemical variables with CC and CG genotypes showed that the mean level of TG in people with CC genotype was increased compared to people with CG genotype in diabetic patients. However, this increase was not significant (p=0.19). CONCLUSIONS There was no association between SNP APOA5 S19W and serum lipids in diabetic patients with and without nephropathy.

Abstract
OBJECTIVES Hepatocellular carcinoma (HCC), the most common form of liver cancer, is a leading cause of tumor-associated mortality worldwide. Diagnosis based upon non-invasive criteria is currently challenged by the need for molecular information that requires tissue or liquid biopsies. The progression of HCC is often associated with chronic inflammation, expression levels of inflammatory mediators, chemokine, and cytokines. In this study, we try to evaluate the PI3K and pro-inflammatory cytokines, TGF-β, IL-1, and IL-6 expression level in patients with liver cancer. MATERIALS AND METHODS The kupffer cells were isolated from patient's specimens. Real-time PCR was applied to evaluate the expression level of PI3K in cell lines or tumors. The concentrations of TGF-β, IL-1, and IL-6 were measured by the quantitative ELISA kit. RESULTS PI3K mRNA expression in cancer cells was increased markedly vs. normal cells. The ELISA results demonstrated over expression of TGF-β, IL-1, and IL-6 in patients and positive correlation between tumor size and stage. DISCUSSION This study suggests that targeting the expression level of PI3K and pro-inflammatory chemokine and cytokines, TGF-β, IL-1, and IL-6, may be a potential diagnostic strategy in HCC patients.

[PMID: 35031424 DOI: 10.1016/j.gene.2021.146174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 12/02/2021] [Accepted: 12/06/2021] [Indexed: 11/24/2022] Open
Abstract
A high prevalence of genetic kidney disease in Tunisia has been detected, and their study provides very important clinical and genetic information. Autosomal dominant polycystic kidney disease (ADPKD) is one of the main causes of morbidity and mortality associated with the kidneys in Tunisia. We present here clinical and genetic characteristics of a cohort of Tunisian patients with ADPKD. Nineteen Tunisian patients with ADPKD, among 4 familial cases and 11 sporadic cases, and 50 Healthy individuals were included in this cohort. Genetic studies of PKD1/2 were carried on using Sanger sequencing and MLPA. In our study, the mean age at diagnosis was 47 ± 18 years. In addition, 84.21% of cases present a family history of ADPKD. Overall, 57.89% of the affected individuals had HTA and 26.31% patients had hematuria. 15.78 % of the patient has extra-renal cysts i.e. one patient with splenic cysts and two patients had liver cysts. 57.89 % of patients were diagnosed with various extra-renal clinical presentations i.e. myopia, hernia, deafness, intracranial aneurysm, respiratory distress, hyperthyroidism, urinary tract infection and lower back pains. The PKD1 genotype showed earlier onset of ESRD compared to PKD2 genotype (43 vs. 55 years old). Six mutations have been detected in PKD1 gene. Among them, three were novels e.g. c.688 T>G, p.C230G and c.690C>G, p.C230W among exon 5 and c.8522A>G, p.N2841S among exon 23. In addition, thirteen single nucleotides polymorphisms have been reported in PKD1 gene. Among them, eleven previously reported in heterozygous state and two novel single nucleotides polymorphisms in heterozygous and homozygous state and predicted to be probable polymorphisms by computational tools: c.496C>T, p.L166= among the exon 4, and c.10165G>C and p.E3389Gln among the exon 31. Only three single nucleotides polymorphisms previously reported in ADPKD database have been identified in PKD2 gene. The description and analysis of our cohort can help in rapid and reliable diagnosis for early management of patients in Tunisia. Indeed, predictive genetic testing can facilitate donor evaluation and increase living related kidney transplantation.

Abstract
Abstract
Background
Male infertility is a heterogeneous disease which can occur due to spermatogenesis defects. The idiopathic azoospermia and oligospermia are the common cause of male infertility with unknown underlying molecular mechanisms. The aim of this study was to investigate association of idiopathic azoospermia and oligospermia with single-nucleotide polymorphisms of CATSPER1, SPATA16 and TEX11 genes in Iranian-Azeri men.
Methods
In this case–control study, we recruited 100 infertile men (case group) and 100 fertile men (control group) from Azeri population in north western provinces, Iran, population. The genomic DNA was extracted using a proteinase K method from peripheral blood leukocytes. The genotypes analysis was conducted using tetra-primer amplification refractory mutation system-polymerase chain reaction method. The obtained data were analyzed by statistical software.
Results
We found a significant difference in the frequencies of heterozygote AB and mutant homozygote BB genotypes in the CATSPER1 (rs2845570) gene polymorphism between patients and healthy controls (p < 0.05). Moreover, we observed a significant difference in the frequencies of heterozygote BA genotype in the SPATA16 (rs1515442) gene polymorphism between patients and healthy controls (p < 0.05). However, no significant difference was found in genotypes distribution of case and control groups in the TEX11 (rs143246552) gene polymorphism.
Conclusion
Our finding showed that the CATSPER1 (rs2845570) and SPATA16 (rs1515442) genes polymorphism may play an important role in idiopathic azoospermia and oligospermia in Iranian Azeri population. However, more extensive studies with larger sample sizes from different ethnic origins are essential for access more accurate results.

Abstract
BACKGROUND AND AIM Vasculogenic mimicry (VM) is one of the most important causes of breast cancer metastasis and resistance against drugs. The cancer stem cells (CSCs) are known as essential factors for VM formation. In this study, the effects of melatonin, Apatinib, and a combination of Apatinib/melatonin on VM formation were investigated by breast CSCs from breast cancer cell line. MATERIALS AND METHODS The percentage of CSCs was determined in two breast cancer cell lines (MCF-7 and MDA-MB-231) by flow cytometry. The effects of Apatinib, melatonin, and a combination of Apatinib/melatonin were evaluated on proliferation and viability, migration and invasion, apoptosis, and VM formation in MDA-MB-231 cells. Moreover, expression levels of the involved proteins in cancer cell proliferation and viability, CSCs, migration and invasion, and VM formation were evaluated by real-time polymerase chain reaction (RT-PCR) and western blotting methods. RESULTS Results of the present study showed that melatonin and Apatinib reduced survival rate of CSCs in a dose- and time-dependent manner. Apatinib, melatonin, and a combination of Apatinib/melatonin inhibited proliferation of breast CSCs (P ≤ 0.001). Formation of VM was decreased in the MDA-MB-231 cancer cell line treated with Apatinib and combination of Apatinib/melatonin. Apatinib and combination of Apatinib/melatonin reduced invasion of breast CSCs (P ≤ 0.0001). Expression of vascular endothelial VE-cadherin, ephrinA2 receptor (EPHA2), p-PI3K/phosphoinositide-3 kinase (PI3K) and phospho-AKT (p-AKT)/AKT ratios was decreased under the influence of Apatinib and a combination of Apatinib/melatonin (P ≤ 0.01). CONCLUSION Apatinib or a combination of Apatinib/melatonin may be used to manage patients with breast cancer. However, further studies are needed to identify anti-cancer mechanisms of melatonin and Apatinib for better management of the patients with breast cancer.

Abstract
INTRODUCTION Guillain-Barré syndrome (GBS) is a common autoimmune disease in the peripheral nervous system. This study aimed to elucidate the role of IL-27 gene polymorphisms in elderly people with GBS. METHODS A total of 395 healthy subjects and 422 GBS patients with an average age of 63 years old were included in this study. Peripheral blood samples were collected. The 2 single-nucleotide polymorphisms (SNPs) of IL-27, namely, rs153109 and rs785575, of GBS patients were analyzed using the PCR method and compared with those of the healthy controls. The correlations of IL-27 SNPs with disease severity, disease outcome, level of anti-GM1 antibodies, and Campylobacter jejuni infection were assessed. Serum levels of IL-27 of healthy subjects and GBS patients were analyzed using enzyme-linked immunosorbent assay. RESULTS No significant differences in the frequencies of rs785575 SNPs between GBS and healthy subjects were observed. In analyzing rs153109 SNPs, the G allele was found to be more prevalent in the GBS patients (p = 0.012). More alleles show GG genotype in GBS patients (p = 0.023). The -964A>G allele has a higher prevalence in severely affected and anti-GM1-Ab-positive GBS patients. GBS patients with the rs153109 SNP showed a poor clinical outcome than those without rs153109 SNP (p = 0.012). GBS patients showed higher serum IL-27 levels than healthy subjects (p < 0.001). The levels of IL-27 were also higher in GBS patients with genotypes of AG and GG, and those with GG genotypes showed the highest IL-27 levels. CONCLUSION The rs153109 SNP is more prevalent in GBS patients with the GG and G allele and is associated with severer GBS, poorer clinical outcomes, and higher IL-27 levels.

Abstract
miRNAs are evolutionarily conserved non-coding ribonucleic acids with a length of between 19 and 25 nucleotides. Because of their ability to regulate gene expression, miRNAs have an important function in the controlling of various biological processes, such as cell cycle, differentiation, proliferation, and apoptosis. Owing to the long-standing regulative potential of miRNAs in tumor-suppressive pathways, scholars have recently paid closer attention to the expression profile of miRNAs in various types of cancer. Melatonin, an indolic compound secreted from pineal gland and some peripheral tissues, has been considered as an effective anti-tumor hormone in a wide spectrum of cancers. Furthermore, it induces apoptosis, inhibits tumor metastasis and invasion, and also angiogenesis. A growing body of evidence indicates the effects of melatonin on miRNAs expression in broad spectrum of diseases, including cancer. Due to the long-term effects of the regulation of miRNAs expression, melatonin could be a promising therapeutic factor in the treatment of cancers via the regulation of miRNAs. Therefore, in this review, we will discuss the effects of melatonin on miRNAs expression in various types of cancers.

Abstract
AIMS The study aimed to examine genetic polymorphism of vitamin D-related genes and association between those genes and vitamin D and cytokines levels in children with type 1 diabetes (T1D). MATERIALS AND METHODS This study was conducted among 100 T1D children and 100 controls at Division of Endocrinology and Metabolism, Department of Pediatrics, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand, during 2016 to 2018. Vitamin D metabolite levels were measured by liquid chromatography-tandem mass spectrometry method, serum cytokine levels of IFN- ɣ, IL-10, IL-13, IL-17α, IL-2, IL-4, IL-6, and TNF-α by immunoassay, and genetic variations at VDR, CYP2R1, CYP27B1, GC, DHCR7, and CYP24A1 by polymerase chain reaction-restriction fragment length polymorphism method. RESULTS A relationship between studied single nucleotide polymorphisms and T1D was found in CYP2R1 (rs10741657) (GA, OR: 1.83, 95% CI: 1.01-3.31; p = 0.04). VDR haplotypes were also remarkably different between T1D patients and controls. Controls had higher frequency of haplotype TACT than T1D patients (p = 0.02). Vitamin D and all cytokine levels, except for IL-17α, were significantly increased in T1D compared to controls. The polymorphism of DHCR7 (rs12785878) was positively associated with 25OHD3 and 3epi25OHD3 levels and was negatively associated with 25OHD2 level. On the other hand, polymorphism of CYP27B1 (rs4646536) was negatively associated with 3epi25OHD3 level. Polymorphisms of CYP27B1 (rs4646536) and GC (rs2282679) were positively associated with TNF-α levels. VDR variation of rs1544410, rs731236, and rs7975232 also showed negative association with IL-10 levels. In contrast, the level of IL-10 was positively associated with DHCR7 (rs12785878). CONCLUSION Relationships between T1D and CYP2R1 polymorphism and VDR haplotype were found. Vitamin D gene-related variations were associated with vitamin D and circulating cytokine levels in children with T1D.

Abstract
OBJECTIVES Breast cancer is a common malignant tumor in women with limited treatment options and multiple side effects. Today, the anti-cancer properties of natural compounds have attracted widespread attention from researchers worldwide. METHODS In this study, we treated 4T1 tumor-bearing Balb/c mice with intraperitoneal injection of Auraptene, paraffin oil, and saline as two control groups. Body weight and tumor volume were measured before and after treatment. Hematoxylin and eosin (H & E) staining and immunohistochemistry of Ki-67 were used as markers of proliferation. In addition, ELISA assays were performed to assess serum IFN-γ and IL-4 levels. RESULTS There was no significant change in body weight in all animal groups before and after treatment. 10 days after the last treatment, Auraptene showed its anti-cancer effect, which was confirmed by the smaller tumor volume and H & E staining. In addition, Ki-67 expression levels were significantly reduced in tumor samples from the Auraptene-treated group compared to the paraffin oil and saline-treated groups. In addition, in tumor-bearing and normal mice receiving Auraptene treatment, IL-4 serum production levels were reduced, while serum levels of IFN-γ were significantly up-regulated in tumor-bearing mice after Auraptene treatment. CONCLUSIONS In the case of inhibition of tumor volume and Ki-67 proliferation markers, Auraptene can effectively inhibit tumor growth in breast cancer animal models. In addition, it might increases Th1 and CD8 + T cell responses after reducing IL-4 serum levels and IFN-γ upregulation, respectively. However, further research is needed to clarify its mechanism of action.

Abstract
Cancer cells are able to undergo aerobic glycolysis and metabolize glucose to lactate instead of oxidative phosphorylation, which is known as Warburg effect. Accumulating evidence has revealed that microRNAs regulate cancer cell metabolism, which manifest a higher rate of glucose metabolism. Various signaling pathways along with glycolytic enzymes are responsible for the emergence of glycolytic dependence. MicroRNAs are a class of non-coding RNAs that are not translated into proteins but regulate target gene expression or in other words function pre-translationally and post-transcriptionally. MicroRNAs have been shown to be involved in various biological processes, including glucose metabolism via targeting major transcription factors, enzymes, oncogenes or tumor suppressors alongside the oncogenic signaling pathways. In this review, we describe the regulatory role of microRNAs of cancer cell glucose metabolism, including in the glucose uptake, glycolysis, tricarboxylic acid cycle and several signaling pathways and further suggest that microRNA-based therapeutics can be used to inhibit the process of glucose metabolism reprogramming in cancer cells and thus suppressing cancer progression.

Abstract
Cancer is the major cause of death worldwide in countries of all income levels. The Hippo signaling pathway is a Drosophila kinase gene that was identified to regulate organ size, cell regeneration, and contribute to tumorigenesis. A huge variety of extrinsic and intrinsic signals regulate the Hippo signaling pathway. The Hippo signaling pathway consists of a wide array of components that merge numerous signals such as mechanical signals to address apoptosis resistance, cell proliferation, cellular outputs of growth, cell death and survival at cellular and tissue level. Recent studies have shed new light on the regulatory role of microRNAs in Hippo signaling and how they contribute to cancer progression. MicroRNAs influence various cancer-related processes such as, apoptosis, proliferation, migration, cell cycle and metabolism. Inhibition and overexpression of miRNAs via miRNA mimics and miRNA inhibitors, respectively, can uncover a hopeful and reliable insight for treatment and early diagnosis of cancer patients. In this review we will discuss our current understanding of regulatory role of miRNAs in Hippo signaling pathway.

Abstract
Breast cancer is the most common cancer among women and its metastasis which generally observed at the last stage is the major cause of breast cancer-related death. Therefore, the agents that have the potential to prevent metastatic and invasive nature of breast cancer can open up new therapeutic strategies. Melatonin, a major hormone of pineal gland, is a powerful anti-cancer agent. There are growing evidence regarding the protective effect of melatonin against cancer invasion and metastasis. The anti-metastatic feature of melatonin accompanies with suppression of tumor proliferation, induction of tumor apoptosis, regulation of the cell cycle, modulating angiogenesis, impediment of invasion, and induction of cancer cells sensitivity to the chemotherapy agents. More recently, anti-metastatic effect of melatonin through affecting cancer stem cells and vascular mimicry has been identified. Thus, the aim of this review is to discuss the potential therapeutic effect of melatonin on breast cancer via modulating the cells invasion and metastasis.

Abstract
OBJECTIVES Recently, oxidative stress (OS) has been described extensively as an important cause of men infertility. The nitric oxide synthase 3 (NOS3) gene expression involved in normal spermatogenesis regulation in testis. Several single nucleotide polymorphisms (SNPs) on NOS3 gene are reported in association with sperm function and spermatogenesis impairment in infertile men. In present study, we investigated association of NOS3 gene rs1799983 G/T polymorphism in Iranian Azeri male with idiopathic asthenozoospermia (AZS). METHODS In this case-control study, we collected 50 males with idiopathic AZS as a case group and 50 age and ethnically matched male as healthy controls from East Azerbaijan area, Iran. The case and control groups genotyping was performed using tetra-primer amplification refractory mutation system-polymerase chain reaction (Tetra-ARMS PCR) method. RESULTS Genotype frequency in AZS patients was 40% GG, 60% GT, and 0% TT, whereas in healthy controls were 60% GG, 30% GT, and 10% TT. Statistical analysis showed that the GT heterozygous genotype frequency of NOS3 gene rs1799983 G/T polymorphism in AZS patients was significantly more than healthy controls (p>0.05). CONCLUSIONS We demonstrated that NOS3 gene rs1799983 G/T polymorphism was associated with AZS in Iranian Azeri men. However, more studies on different geographic areas, races and ethnicities are required to determine exact role of NOS3 gene rs1799983 G/T polymorphism in idiopathic AZS.

Association of IL-33 gene rs16924159 polymorphism and recurrent pregnancy loss in Iranian Azeri women. Horm Mol Biol Clin Investig 2020; 41:/j/hmbci.ahead-of-print/hmbci-2020-0010/hmbci-2020-0010.xml. [PMID: 32623850 DOI: 10.1515/hmbci-2020-0010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2020] [Accepted: 04/04/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Recurrent pregnancy loss (RPL) referred to two or more consecutive abortions before 20th week of pregnancy. The imbalance of inflammatory factors such as interleukins (IL) can be a significant factor in the RPL. The aim of this study was to investigate association of interleukin-33 (IL-33) gene rs16924159 polymorphism and RPL in Iranian Azeri women. MATERIALS AND METHODS This case-control study consisted of 100 women with RPL as case group and 100 healthy controls with successful delivery. Genomic DNA was extracted from whole blood samples using salting out method. The fragments of the rs16924159 polymorphism were amplified by PCR and the genotyping was performed using DNA sequencing. RESULTS The obtained results showed that frequency of GA genotype and G allele of rs16924159 polymorphism in the case group was significantly more than healthy controls (p = 0.033). CONCLUSIONS Generally, we showed that the IL-33 gene rs16924159 polymorphism may play an important role in risk of RPL in the Iranian Azeri women. However, further studies on different races and geographic areas can be useful in identification of effects of rs16924159 polymorphism on RPL.

The apatinib inhibits breast cancer cell line MDA-MB-231 in vitro by inducing apoptosis, cell cycle arrest, and regulating nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways. Breast Cancer 2020; 27:613-620. [PMID: 32026267 DOI: 10.1007/s12282-020-01055-6] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Accepted: 01/17/2020] [Indexed: 12/22/2022]
Abstract
BACKGROUND AND PURPOSE Breast cancer is one of the most common cancers and leading causes of death in the women worldwide. The evidence shows efficacy of apatinib against breast cancer. Accordingly, the present study was conducted to investigate the effect of apatinib on apoptosis, cell cycle, and Mitogen‑Activated Protein Kinase (MAPK) and nuclear factor-κB (NF-κB) signaling pathways in the breast cancer MDA-MB-231 cell line. METHODS The effects of apatinib on viability, morphology, tumor spheroid, cell cycle, migration, invasion, and apoptosis of MDA-MB-231 breast cancer cells were evaluated in vitro. In addition, expression of proteins involved in NF-κB and MAPK signaling pathways was evaluated using the western blotting analysis. RESULTS Apatinib decreased viability, tumor spheroid, migration, and invasion of MDA-MB-231 cells. Furthermore, apatinib altered morphology and regulated cell cycle which followed by apoptosis induction in MDA-MB-231 cells. Apatinib decreased expression of p-p65 and p65 proteins in NF-κB signaling pathways and increased expression of p38, p-p38, JNK, and p-JNK in MAPK signaling pathways. CONCLUSION The results suggested that apatinib can inhibit proliferation, migration and invasion of breast cancer cell line MDA-MB-231 through inducing apoptosis, cell cycle arrest, and regulating NF-κB and MAPK signaling pathways.

Abstract
Background: The etiology of allergic rhinitis includes an increase in cytokine levels, including IL- 4, IL-13, IL-17, and reduction in B7 homologous 1 (B7-H1) or programmed cell death-1 ligand-1 (PD-L1), a new member of the CD28: B7 stimulant molecule family. The aim of this study was to determine the relationship between cytokines and PD-L1. Methods: In this experimental study, 80 patients with allergic rhinitis were enrolled according to inclusion and exclusion criteria. The severity and stage of the disease were determined by a specialist physician. A 5 cc venous blood sample was collected from the patients. IL-4, IL-17, INFγ and PD-L1 were measured using ELISA technique. Results: There was a significant correlation between SPD-L1 and INFγ, IL-4 and IL-17 in allergic rhinitis patients (P < 0.05). Statistical analysis based on the severity of the disease (Mild, Moderate and Severe) showed a significant positive correlation between the SPD-L1 and INFγ in all three levels (P < 0.001). There was also a significant negative correlation between SPD-L1 and two cytokines IL-4 and IL-17 (P < 0.001). Conclusion: PD-L1 may have a protective role against allergic rhinitis, although the precise mechanism requires further detailed studies.
