HOTAIR is a known long non-coding RNA which has recently been associated with the progression of some cancer types. It has been reported that HOTAIR expression is correlated with SUZ12 expression level and therefore may affect the epigenetic state of cancer tissues. Here, we found aberrant up-regulation of HOTAIR in gastric adenocarcinoma samples compared(More)
Glioblastoma is an invasive tumor of the central nervous system. Tumor recurrence resulting from ineffective current treatments, mainly due to the blood-brain barrier, highlights the need for innovative therapeutic alternatives. The recent availability of nanotechnology represents a novel targeted strategy in cancer therapy. Natural products have received(More)
BACKGROUND Hepatocellular carcinoma is the fifth most common cancer worldwide, with poor prognosis and resistance to chemotherapy. This gives novel cancer treatment methods an overwhelming significance. Epigenetic therapy of cancer is useful in reversing some of the cancer defects because of reversibility of the epigenetic alterations. Non-protein coding(More)
Molecular phylogenetic analysis of a novel thermophilic eubacterium isolated from an Iranian hot spring using 16S rDNA sequence showed that the new isolate belongs to genera Geobacillus. DNA pol I gene from this isolate was amplified, cloned, sequenced, and the three-dimensional (3D) structure of deduced amino acid sequence was predicted. Sequence analysis(More)
The Drosophila γ-glutamyl carboxylase (dγC) has substrate recognition properties similar to that of the vertebrate γ-carboxylase (γC), and its carboxylated product yield, in vitro, was shown to be more than that obtained with the human enzyme. However, whether the Drosophila enzyme is able to γ-carboxylate the human vitamin K-dependent (VKD) proteins, such(More)
Exposure to ionizing radiation (IR) could be detrimental to health. Oxidative stress, DNA damage, and inflammation are implicated in radiation damage. Curcumin, a natural polyphenol, has remarkable antioxidant, anti-inflammation and anticarcinogenic properties and is reported to protect cells and organisms against gamma-rays. We have recently enhanced(More)
This study investigated the therapeutic effect of crocetin, a carotenoid derived from saffron, on gastric adenocarcinoma (AGS) cells and 1-methyl-3-nitro-1-nitrosoguanidine (MNNG)-induced gastric cancer in rats. An MTT assay showed a significant dose- and time-dependent inhibition of AGS cell proliferation as a result of crocetin administration. Flow(More)
Benzene is a known environmental pollutant with demonstrated leukemogenic activity. Marrow mesenchymal stem cells (MSCs), contribute to skeletal remodeling and repair. They also support haematopoiesis constructing important elements of haematopoietic niche. In the present study, the effects of a range of benzene concentrations along with those of its(More)
Human endometrium contains mesenchymal stem cells (eMSC) which have the ability to differentiate into three cell lineages and the potential in therapeutic applications. We hypothesize that using environmental induction in culture media such as dexamethasone, human recombinant insulin and human epidermal growth factor (hEGF) can differentiate endometrial(More)
Streptomyces commonly produce ectoines as compatible solutes to prevent osmotic stresses. Fine structure of the genes producing ectoine (ectC) and hydroxyectoine (ectD) enzymes in Streptomyces rimosus C-2012 as a slightly halophilic bacterium is reported in this study. Deduced amino acid sequences of ectC and ectD genes from strain C-2012 and some other(More)
