Abstract
Nucleophosmin (NPM1) is a well-known nucleocytoplasmic shuttling protein that performs several cellular functions such as ribosome biogenesis, chromatin remodeling, genomic stability, cell cycle progression, and apoptosis. NPM1 has been identified to be necessary for normal cellular functions, and its altered regulation by overexpression, mutation, translocation, loss of function, or sporadic deletion can lead to cancer and tumorigenesis. In this review, we focus on the gene and protein structure of NPM1 and its physiological roles. Finally, we discuss the association of NPM1 with various types of cancer including solid tumors and leukemia.

Abstract
BACKGROUND Deregulated PIN1 is associated with cancer development and progression. Herein, for the first time, we evaluate the roles that PIN1 in tumorigenic characteristics of colorectal cancer (CRC) cells. METHODS In this study, PIN1 expression was knocked down in SW-48 cells by synthetic small interfering RNA (siRNA). After confirming the knockdown of PIN1, cell viability, colony formation, apoptosis, autophagy, cancer stem cell (CSC)-related genes, CSC-related signaling pathways, cell migration, and 5-FU chemosensitivity were evaluated in vitro. RESULTS Transfection of PIN1 siRNA into SW-48 cells inhibited cancer cell proliferation, migration, and increased apoptosis and autophagy. Transfected SW-48 cells had lower properties of CSCs through the inhibition of β-catenin and Notch1 gene expression. Moreover, inhibition of PIN1 enhanced the inhibitory effect of 5-FU on SW-48 cell proliferation. CONCLUSION Our results indicated that targeting of PIN1 serves as a promising therapeutic solution for the suppression of tumor progression processes in CRC.

Abstract
Inflammation plays an important role in the development of several cancers. Inflammatory cytokines, including tumor necrosis factor-α (TNF-α), are associated with the induction of inflammation. Chronic inflammation contributes to the progression of cancer through several mechanisms, including increased cytokine production and activation of transcription factors, such as nuclear factor-κB (NF-κB). Zerumbone (ZER), a component of subtropical ginger (Zingiber zerumbet Smith), seems to have anti-inflammatory, anti-cancer, and antioxidant activities. In this study, we aimed to explore the protective function and mechanisms of ZER against TNF-α-induced cancer-promoting cytokines. We found that the viability of stimulated human fibroblast cell lines was reduced after treatment with ZER (IC50=18 µmol/L), compared to un-stimulated fibroblasts (IC50=40 µmol/L). Besides, ZER inhibited mRNA expression and protein secretion of transforming growth factor-β (TGF-β), interleukin-33 (IL-33), monocyte chemoattractant protein-1 (MCP-1), and stromal cell-derived factor 1 (SDF-1), which were produced by TNF-α-induced fibroblasts, as measured by quantitative real time-PCR (qRT-PCR) and ELISA assays. The mRNA expression levels of TGF-β, IL-33, SDF-1, and MCP-1 showed 8, 5, 2.5, and 4-fold reductions, respectively. Moreover, secretion of TGF-β, IL-33, SDF-1, and MCP-1 was reduced to 3.65±0.34 ng/mL, 6.3±0.26, 1703.6±295.2, and 5.02±0.18 pg/mL, respectively, compared to the untreated group. In addition, the conditioned media (CM) of TNF-α-stimulated fibroblasts increased the NF-κB expression in colorectal cancer cell lines (HCT-116 and Sw48), while in the vicinity of ZER, the expression of NF-κB was reversed. Considering the significant effects of ZER, this component can be used as an appropriate alternative herbal treatment for cancer-related chronic inflammation.

Abstract
Cross-talk among inflammation and colorectal cancer cells is chiefly reported through a complex of cytokines, chemokines, and growth factors. MicroRNA performs strategic roles in controlling a variety of signaling cascades. miR-34a is known as a master regulator of tumor suppression. Combined application of different miRNA-based agents and chemotherapeutic drugs has been used to augment drug sensitivity and may reinforce the antitumor effect. A lot of studies specify a substantial increase in the effectiveness of combination therapies. The anti-inflammatory activity of Zerumbone (ZER) was investigated in many cancers. In this study the level of the inflammatory cytokines including CXCL-12 (SDF-1), CCL-2 (MCP-1), TGF-β and IL-33 has been measured in pmiR-34a-5p transfected and pmiR-34a-5p +ZER treated CRC cell lines (HCT-116 and SW48) by QRT-PCR and ELISA methods, respectively. The results showed that miR-34a could significantly inhibit cytokine expression in both cell lines for 48 and 72 h except SDF-1 which no inhibition was observed in SW48 cells. ZER suppressed SDF-1 for all three time points in both cell lines, while in SW48 cells IL-33 and TGF-β were inhibited in 72 h and in HCT-116 cells MCP-1 diminished for only 24 h and TGF-β diminished for all three times. Combination of both miR-34a and ZER suppressed TGF-β, SDF-1 and MCP-1 in HCT-116 cells in all time points while in SW48 cells, suppression of most cytokines was observed in 48 and 72 h. Furthermore Colony formation assay and scratch test were employed to detect changes of proliferation and migration in CRC transfected and treated cells. Generally, we found that miR-34a could considerably decrease the expression of inflammatory cytokines and the combination of ZER+ miR-34 boosted this effect. Moreover the migration and proliferation decreased in treated and transfected cells and this reduction was more severe in miR-34a +ZER treatment. It is important to note that in the case of cell resistance to each of these therapeutic agents, inhibition of cytokines can be compensated by another one.

Abstract
Background. The present study aimed to examine the long-term impact of CS on Executive Function (EF) and memory among older adults living in the community. Methods. Clock Drawing Test (CDT) and Delayed Word Recall Test (DWRT) were used to examine EF and memory, respectively, using four waves of National Health and Aging Trend Study. The respondents were asked whether they have ever smoked, length of smoking, and age of start and quit smoking. Results. CS can have a long-term impact on both EF and memory. However, current smoking can increase the risk of EF impairment compared to former smokers. Lung disease and current smoking can have a synergic effect of impairment in EF. Conclusion. In the long-term, smoking can negatively affect cognitive. Lung diseases and smoking can synergize their impacts on EF. The impact of smoking on cognition varies across ethnic groups; hence, educational programs targeting minorities can reduce discrepancies.

Abstract
Aging is considered as inevitable changes at different levels of genome, cell, and organism.
From the accumulation of DNA damages to imperfect protein homeostasis, altered cellular communication
and exhaustion of stem cells, aging is a major risk factor for many prevalent diseases, such as
cancer, cardiovascular disease, pulmonary disease, diabetes, and neurological disorders. The cells are
dynamic systems, which, through a cycle of processes such as replication, growth, and death, could
replenish the bodies’ organs and tissues, keeping an entire organism in optimal working order. In many
different tissues, adult stem cells are behind these processes, replenishing dying cells to maintain normal
tissue function and regenerating injured tissues. Therefore, adult stem cells play a vital role in preventing
the aging of organs and tissues, and can delay aging. However, during aging, these cells also
undergo some detrimental changes such as alterations in the microenvironment, a decline in the regenerative
capacity, and loss of function. This review aimed to discuss age-related changes of stem cells in
different tissues and cells, including skin, muscles, brain, heart, hair follicles, liver, and lung.

Abstract
BACKGROUND Despite the dramatic efficacy of ABT-737, a large percentage of cancer cells ultimately become resistance to this drug. Evidences show that over-expression of Mcl-1 is linked to ABT-737 resistance in NSCLC cells. The aim of this study was to investigate the effect of miRNA-101 on Mcl-1 expression and sensitivity of the A549 NSCLC cells to ABT-737. METHODS After miRNA-101 transfection, the Mcl-1 mRNA expression levels were quantified by RT-qPCR. Trypan blue staining was used to explore the effect of miRNA-101 on cell growth. The cytotoxic effects of miRNA-101 and ABT-737, alone and in combination, were measured using MTT assay. The effect of drugs combination was determined using the method of Chou-Talalay. Cell death was assessed using cell death detection ELISA assay kit. RESULTS Results showed that miRNA-101 markedly suppressed the expression of Mcl-1 mRNA in a time dependent manner, which led to A549 cell proliferation inhibition and enhancement of apoptosis (p < 0.05, relative to blank control). Pretreatment with miRNA-101 synergistically decreased the cell survival rate and lowered the IC50 value of ABT-737. Furthermore, miRNA-101 dramatically enhanced the apoptotic effect of ABT-737. Negative control miRNA had no remarkable effect on cellular parameters. CONCLUSIONS Our findings propose that suppression of Mcl-1 by miRNA-101 can effectively inhibit the cell growth and sensitize A549 cells to ABT-737. Therefore, miRNA-101 can be considered as a potential therapeutic target in patients with non-small cell lung cancer. .

Abstract
Abstract
Objectives
Down-regulation of miRNA-7 is correlated with over-expression of IRS-1 and IRS-2 proteins, the upstream regulators of IGF-1R/Akt pathway, in glioblastoma cells. In this study, the effect of miRNA-7 on expression of IRS-1 and IRS-2 and sensitivity of the U373-MG glioblastoma cells to erlotinib was explored.
Methods
After miRNA-7 transfection, the expression of IRS-1 and IRS-2 mRNAs was measured by RT-qPCR. Trypan blue assay was used to assess the effect of miRNA-7 on cell proliferation. The effects of miRNA-7 and erlotinib, alone and in combination, on cell survival and apoptosis were measured using MTT assay and ELISA cell death assay, respectively.
Key findings
Our data showed that miRNA-7 markedly inhibited the expression of IRS-1 and IRS-2 in a time-dependent manner, inhibited the proliferation of glioblastoma cells and enhanced apoptosis (P < 0.05, relative to control). Pretreatment with miRNA-7 synergistically inhibited the cell survival rate and decreased the IC50 of erlotinib. Furthermore, miRNA-7 significantly augmented the apoptotic effect of erlotinib.
Conclusions
Our data propose that inhibition of IRS-1 and IRS-2 by miRNA-7 can effectively induce apoptosis and sensitize glioblastoma cell to EGFR-TKIs. Therefore, miRNA-7 may be a potential therapeutic target in patients with glioblastoma.

Abstract
It has been shown that the blockade of chemokine receptor type 5 can dampen inflammatory reaction within the central nervous system (CNS). In the present study, we utilized maraviroc, a potent antagonist o CCR5, to examine whether this drug can mitigate neuroinflammation in the spinal cord of mice induced by experimental autoimmune encephalitis (EAE), considered a murine model of multiple sclerosis (MS). For this aim, mice were immunized with myelin oligodendrocyte glycoprotein 35-55 (MOG35-55), followed by pertussis toxin to induce paralysis in EAE mice. The animals intraperitoneally received various doses of maraviroc (5, 25, and 50 mg/kg body weight) when the early clinical signs of EAE appeared. The results demonstrated that the administration of maraviroc led to a marked decrease in the clinical score and improvement in behavioral motor functions. Moreover, our finding indicated that the administration of maraviroc significantly attenuates the infiltration of inflammatory cells to the spinal cord, microgliosis, astrogliosis, pro-inflammatory cytokines, and cell death in EAE mice. The flow cytometry data indicated that a decreased number of CD4+ and CD8+ T cells in the peripheral blood of mice with EAE without affecting the number of T regulatory cells (CD4 + CD25+ forkhead box protein 3+). Finally, it seems that maraviroc is well-tolerated, and targeting CCR5 could open up a new horizon in the treatment of MS.

Abstract
As the SARS-CoV-2 (COVID-19) pandemic spreads rapidly, there is need for a diagnostic test with high accuracy to detect infected individuals especially those without symptoms. Real-time polymerase chain reaction (RT-PCR) is a common molecular test for diagnosing SARS-CoV-2. If some factors are not taken into consideration when performing this test, it can have a relatively large number of false negative results. In this article, we discuss important considerations that could lead to false negative test reduction.

Abstract
Abstract- Small interfering RNAs (siRNA) technology has shown great promise as a new class of therapeutic interventions for the treatment of cancer and other diseases. It is a remarkable endogenous pathway that can regulate sequence-specific gene silencing. Despite the excitement about possible applications of this biological process for sequence-specific gene regulation, the major limitations against the use of siRNA-based therapeutics are their rapid degradation by serum nuclease, poor cellular uptake, and rapid renal clearance following systemic delivery, off-target effects and the induction of immune responses. Many researchers have tried to overcome these limitations by developing nuclease-resistant chemically-modified siRNAs and a variety of synthetic and natural biodegradable lipids and polymers to enhance the efficacy and safety profiles of siRNA delivery. Ideal siRNA-based delivery systems for cancer therapy must be clinically suitable, safe and effective. In this review, we introduce the greatest challenges in achieving efficient RNAi delivery and discuss design criteria and various delivery strategies for cancer therapy, including chemical modifications, lipid-based nano-vectors, polymer-mediated delivery systems, conjugate delivery systems, and others.

Abstract
BACKGROUND Viruses are considered the most common cause of infectious conjunctivitis. PCR has been approved as the best standard method to diagnose viral conjunctivitis. This study was conducted to investigate epidemiological patterns of conjunctivitis in Hamadan, west Iran. In addition, the frequency of the most important cause of infectious conjunctivitis diagnosed by PCR and its seasonal variations and association with certain socioeconomic and health factors were studied. METHODS In this cross-sectional study, 125 patients with suspected viral conjunctivitis or keratoconjunctivitis in Hamadan, west Iran from July 2016 to June 2017 were examined for the presence of herpes simplex virus 1 (HSV1), HSV2, varicella-zoster virus (VZV), adenovirus. and Chlamydia trachomatis using multiplex real-time PCR. RESULTS Adenoviruses were the most prevalent pathogens (94.4%). HSV1 was found in two (1.6%) patients. HSV2, VZV, and C. trachomatis were not seen in any patients. There was no difference in acquisition of conjunctivitis between men and women. A total of 55 (44%) patients attended the clinics in summer. CONCLUSION This study demonstrated that adenoviruses were a much more common viral cause of conjunctivitis in the studied region compared to findings in other regions. In addition, the acquisition rate of eye infection is expected to decrease dramatically in this region through control of adenoviruses. Demographic variables ie, age, sex, and income level, were not significantly associated with acquisition of viral infection.

Abstract
Ferula species have diverse biological functions. This study set out to investigate the anti-proliferative effects of methanolic extract of F. pseudalliacea against human colon cancer HCT-116 cell line. Cytotoxic effects of F. pseudalliacea on HCT-116 cells was estimated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay. Real-time polymerase chain reaction (PCR) and Western blot were employed to analyze BAX and Bcl2 expression. Cell cycle analysis and apoptosis were conducted using flowcytometry and Annexin V/ propidium iodide (PI) staining. Rhodamine 123 staining and enzyme-linked immunosorbent assay (ELISA) assay were employed to quantify the mitochondria membrane potential (MMP) and caspase 3 activity, respectively. F. pseudalliacea markedly decreased HCT-116 cells viability. The gene and protein expression of BAX were increased, whereas Bcl-2 was decreased in F. pseudalliacea treated cells. F. pseudalliacea induced apoptosis via promotion of cell cycle arrest, caspase 3 activation, and destruction of MMP. These results demonstrate that F. pseudalliacea extract is able to induce apoptosis in HCT-116 cells mainly by activation of the mitochondrial pathway.

Abstract
AIMS MicroRNAs (miRNAs) are small noncoding RNAs that negatively control gene expression at the translational level. There are compelling evidences indicating that the expression of let-7e is downregulated in various cancers, however, the role of let-7e in colorectal cancer (CRC) and its mechanism has been remained unknown. Here, we investigated the potential role of let-7e in regulating CRC cells phenotypes. MAIN METHODS Let-7e and DCLK1 siRNA were transfected in HCT-116 cells. Colony formation assay, scratch test, Annexin V/PI flow cytometry, and sphere formation assay were performed to examine the cell proliferation, migration, apoptosis, and stemness, respectively. The expression of let-7e, epithelial-mesenchymal transition (EMT)-related genes, Doublecortin like kinase protein 1 (DCLK1), and cancer stem cells (CSCs) were assessed using RT-qPCR while the protein level of DCLK1 was determined by western blotting. KEY FINDINGS Overexpression of let-7e effectively inhibited cell proliferation, suppressed migration, reduced sphere formation, and precluded EMT process as well as stemness factors. Furthermore, let-7e suppressed DCLK1 expression. Additionally, we found that the expression of let-7e was negatively correlated with DCLK1 expression in CRC cells. SIGNIFICANCE Let-7e plays an important role as tumor suppressor miRNA in CRC probably through inhibition of DCLK1 expression.

Abstract
Objectives The emergence of resistant bacteria is being increasingly reported around the world, potentially threatening millions of lives. Amongst resistant bacteria, methicillin-resistant Staphylococcus aureus (MRSA) is the most challenging to treat. This is due to emergent MRSA strains and less effective traditional antibiotic therapies to Staphylococcal infections. The use of bacteriophages (phages) against MRSA is a new, potential alternate therapy. In this study, morphology, genetic and protein structure of lytic phages against MRSA have been analysed. Methods Isolation of livestock and sewage bacteriophages were performed using 0.4 μm membrane filters. Plaque assays were used to determine phage quantification by double layer agar method. Pure plaques were then amplified for further characterization. Sulfate-polyacrylamide gel electrophoresis and random amplification of polymorphic DNA were run for protein evaluation, and genotyping respectively. Transmission electron microscope was also used to detect the structure and taxonomic classification of phage visually. Results Head and tail morphology of bacteriophages against MRSA were identified by transmission electron microscopy and assigned to the Siphoviridae family and the Caudovirales order. Conclusion Bacteriophages are the most abundant microorganism on Earth and coexist with the bacterial population. They can destroy bacterial cells successfully and effectively. They cannot enter mammalian cells which saves the eukaryotic cells from lytic phage activity. In conclusion, phage therapy may have many potential applications in microbiology and human medicine with no side effect on eukaryotic cells.

Abstract
The current study explored the basic molecular mechanisms of zerumbone (ZER), an herbal compound, in inhibiting the migration and invasion of colorectal cancer (CRC) cells in vitro. Two types of CRC cells, namely HCT-116 and SW48, were treated with various concentrations of ZER (8, 16, and 24 µM) for 24, 48, and 72 h, respectively. In vitro assays were performed to determine alterations in proliferation ability, mRNA expression and protein levels, and migration and invasion potential of CRC cells. An SYBR Green-based quantitative polymerase chain reaction (PCR) was utilized to detect the gene expression of focal adhesion kinase (FAK), nuclear factor (NF)-κB, and urokinase-type plasminogen activator (uPA) followed by the evaluation of the level of proteins by western blotting. Migration and invasion potentials of HCT-116 and SW48 cells treated by ZER were examined using migration and invasion assay kits, respectively. We compared the results of all experiments with control groups, including FAK inhibitor, ZER + FAK inhibitor-treated cells, NF-β inhibitor, ZER + NF-β inhibitor, and untreated cells. The data in the present study suggest that ZER may exert its antimetastatic effects through inhibition of FAk/PI3k/NF-κB-uPA signaling pathway, thereby possibly representing a novel class of FAK inhibitors.

Abstract
OBJECTIVE Scorpion venom, considered as a treasure trove of various bioactive molecules, is a new approach to induce cancer cell death via apoptosis pathways. In the present study, we evaluated for first time the anti-proliferative efficacy of Hemiscorpius lepturus scorpion venom and its pathway on a colon carcinoma cell. MATERIALS AND METHODS The CT26 and VERO cell lines were treated with various concentrations of the venom. The IC50 values were estimated by MTT assay test, and the apoptosis was evaluated by flow cytometry. Moreover, RT-PCR analysis was used to investigate the levels of Bax, Bcl2, Trp53, and Casp3 mRNA expression. The mice xenograft model was established to evaluate the therapy efficiency of venom. Some valuable exponential growth parameters were evaluated in treated mice. RESULT The scorpion venom inhibited the growth of CT26 cells with an IC50 value about 120 μg/ml. However, VERO cells increased to 896 μg/ml under the same condition. A remarkable apoptotic cells in CT26 cells were revealed by flow cytometry assay. A significant over-expression was observed in Bax, Casp3, and Trp53 and downregulated in Bcl2 mRNA level in tumor tissue after treatment with scorpion venom (p < 0.05). All changes of valuable exponential growth parameters showed a shrinking tumor size. CONCLUSION Our findings indicated that Hemiscorpius lepturus venom has a special anti-proliferative effect on CT26 cells via Trp53/Bcl2/Casp3 pathway. Considering its powerful cytotoxic vigor against a colon cancer cell (CT26) and low toxicity to non-tumorigenic cell (VERO), we propose that this venom probably has a specific effect on other colon cancer cells and may turn out to be a novel therapeutic strategy in treating colon cancer.
