The significance of producing superhydrophobic surfaces through modification of surface chemistry and structure is in preventing or delaying biofilm formation. This is done to improve biocompatibility and chemical and biological properties of the surface by creating micro-nano multilevel rough structure; and to decrease surface free energy by Fault Tolerant Control Strategy (FTCS) . Here, we pr...
Wnt signaling pathways are essential for bone formation. Previous studies showed that Wnt signaling pathways were regulated by miR-375. Thus, we aim to explore whether miR-375 could affect osteogenesis. In the present study, we investigated the roles of miR-375 and its downstream targets. Firstly, we revealed that miR-375-3p negatively modulated osteogenesis by suppressing positive regulators o...
Background :Wide distribution and low half-life of acyclovir has led to a high dose consumption of the drug. Recent studies have shown that encapsulation of acyclovir in nano-carriers can increase effectiveness and decrease its side effects. We investigated the inhibitory effect of acyclovir loaded nano-niosomes against herpes simplex virus type-1 (HSV-1) in cell culture. Methods : In-vitro...
objective: mesenchymal stem cells (mscs) can differentiate into various cell types. since cysteine has structural similarities to neuronal inducers β-mercaptoethanol and glutathione, we examined its effect on neural induction of rat bone marrow mscs. materials and methods: in this experimental study, cells were treated in a medium containing 1mm cysteine for 24 hours prior to treatment with neu...
Introduction: CSCs have been identified in prostate cancer (PCa), one of the most diagnosed malignancies in men over the world, for which radiation resistance is a major problem in the treatment of advanced stages. Cancer stem cells (CSCs) have the ability to self-renew and differentiate to give rise to heterogeneous phenotype of the tumor cells. It is believed that CSCs are ...
Background: Germ cell development processes are influenced by soluble factors and intercellular signaling events between them and the neighboring somatic cells. More insight into the molecular biology of the germ cell development from embryonic stem (ES) cells and investigation of appropriate factors, specifically those targeting differentiation process, is of great importance. In this study, w...
We examined the influence of caffeine on the proliferation and apoptosis of β cells cultured in vitro in the presence of the free fatty acid palmitic acid (PA). Different concentrations of caffeine (1-100 mM) and free fatty PA were added to cultured β cells. The MTT assay was used to analyze cell proliferative activity; flow cytometry was used to measure apoptosis and calculate the apoptosis ra...
conclusions p. gingivalis and p. intermedia could play a role in implant failure by changing the expression profiles of genes related to bone formation and resorption. results viability was reduced to 56.8% (p. gingivalis) and 52.75% (p. intermedia) at 1000 multiplicity. amongst 48 genes examined, expressions of bmper, smad1, il8 and nfrkb were found to be highly upregulated by both bacterial c...
Retinoblastoma is a pediatric retinal tumor caused by mutational inactivation of the tumor suppressor pRb, and the present study aims to examine the role of kaempferol in retinoblastoma and explore its underlying molecular mechanisms. The mRNA and protein expression levels were measured by quantitative real time PCR (qRT-PCR) and western blot, respectively; cell growth and invasion was determin...
Objective(s): Hepatocellular carcinoma (HCC) is one of the leading fatal neoplasms and the most common primary liver malignancy worldwide. Peptide hormone ANGPTL8 (betatrophin) may act as an important regulator in HCC development through the Wnt/β-catenin pathway. We aimed to evaluate the effects of recombinant ANGPTL8 on Wnt/β-catenin signaling in human liver carcinom...
