Abstract Cervical cancer (CC), has been identified as one of the most frequent malignant tumors all over the world, with high mortality in females. A growing number of investigations have confirmed that long noncoding RNAs (lncRNAs) play a crucial role in the progression of multiple cancers. Nonetheless, the biological function and regulatory mechanism of LINC01772 in CC haven’t been explored so far. In this study, LINC01772 expression was found to be upregulated in tissues and cells of CC. Knocking down LINC01772 suppressed CC cell proliferation, migration and epithelial-mesenchymal transition (EMT) process. Through molecular mechanism assays,… More >

Abstract Stroke remains the leading cause of death and disability worldwide, which destroys the quality of patients’ lives and thus is becoming a heavy burden to the society. However, the current therapeutic approaches are far from satisfaction. The objective of this study is to elucidate the impact of nerve growth factor (NGF) on the brain damage induced by cerebral ischemia and its potential molecular mechanism. Middle cerebral artery occlusion (MCAO) rats were used as animal models and neurological functions were evaluated by modified Neurological Severity Score (NSS). Brain cell apoptosis was analyzed by TUNEL-positive staining while… More >

Abstract Ovarian lesions are commonly encountered pathologies that cannot be categorized clinicoradiologically. Definite diagnosis is of great importance for therapeutic and prognostic purposes. Histopathology gives accurate diagnosis in most cases. Few cases need supportive tests like immunohistochemistry. Objective: to study the histomorphological diversity of ovarian lesions, their age and location in North of Iraq (Mosul and Duhok). Patients and methods: In the period extended from January 2008 to December 2011, 161 cases of ovarian lesions were collected from pathology departments in Azadi General Hospital “Duhok” and Al-Jamhori Teaching Hospital “Mosul”. Automated tissue processor was used More >

Abstract Several toxic compounds are known to induce apoptosis in mammalian cell lines. The human neuroblastoma cells (SH-SY5Y) were exposed to the phosphatase inhibiting toxin okadaic acid (OA) or hydrogen peroxide (H2O2) to induce apoptosis as well as generate reactive oxygen species (ROS). Mitoxantrone (MXT) was used as a positive control for apoptosis. The SH-SY5Y cells were transfected with eukaryotic expression plasmid pHyPer-dMito encoding mitochondrial-targeted fluorescent or pHyPer-dCito encoding cytoplasmic-targeted fluorescent sensor for hydrogen peroxide (HyPer). The ERp57, also called GRP58 (Glucose-regulated protein 58), is a stress protein induced in conditions like glucose starvation and More >

Abstract The aim of the current research was to clone and to characterize the partial 66 kDa streptavidin-binding peptide (SBP) found in the germinated embryos of Pisum sativum L. var. Alaska. The pea (P. sativum var. Alaska) embryos possess prominent 66 kDa SBPs that gradually disappeared after few hours of germination in germinated embryos, but not in the cotyledons. The total RNA was isolated from embryos of P. sativum but could not be isolated from the cotyledons. The partial nucleotides sequences of 66 kDa SBPs of embryonic stalk (P. sativum var. Alaska) were cloned and identified using pMOSBlue vector.… More >

Abstract Maintenance of pluripotency depends to diverse regulatory factors. Studies in embryonic stem cells (ESCs) have indicated that large intergenic non-coding RNAs (lincRNAs) are involved in the regulatory network of pluripotency. However, the presence and function of pluripotency-associated lincRNAs in cancer cells with pluripotency features are unknown. In this study, we used embryonal carcinoma (EC) P19 cell lines to investigate the expression level of Halr1 in pluripotency and retinoic acid (RA)-induced differentiated states. Down-regulation of pluripotency associated factors such as OCT4, NANOG, SSEA1 and alkaline phosphatase at transcript and protein levels were used to confirm More >

Abstract X-ray repair cross-complementing protein 1 (XRCC1) could repair cisplatin-induced DNA damage. XRCC1 Arg399Gln and Arg194Trp variants alter XRCC1 expression and function, leading to changes in cancer sensitivity to cisplatin treatment. This study aimed to investigate the effects of XRCC1 Arg399Gln and Arg194Trp polymorphisms on cell viability, apoptosis and XRCC1 expression in cisplatin-sensitive A549 and cisplatin-resistant A549/DDP nonsmall cell lung cancer (NSCLC) cells. Plasmids carrying XRCC1 Arg399Gln and Arg194Trp were constructed and transfected into A549 and A549/DDP cells. RT–PCR, Western blot, MTT assay, and flow cytometry analysis were performed to assess cell viability, apoptosis, and More >

Abstract This study aimed to investigate the microRNA expression profile and the characteristics of lipid metabolism in the livers of rats undergoing a high-fat diet. Fifty male Sprague-Dawley (SD) rats were divided into a standard chow group (C group, N = 10) and a high-fat diet group (H group, N = 40). After 12 weeks, the rat body weight, body length, fat mass, and serum lipid concentration were measured. The expression profile of microRNAs and the gene and protein expression levels involved in lipid metabolism in rat liver were detected. Body fat and serum lipid… More >

Abstract Glioma is the most common primary malignant brain tumor with a poor survival rate. In recent years, no significant progress has been made in the treatment of gliomas in contrast to the development of improved diagnosis via molecular typing. Newcastle disease virus (NDV), a negative-stranded RNA virus that exhibits oncolytic activity, has been investigated for its capacity to elicit antitumor activity in many types of cancers, including glioma. Therefore, application of oncolytic viruses, such as NDV, as a new treatment strategy to specifically target aberrant signaling in glioblastomas has brought new hope. For many years, More >

Abstract The expression of a gene is governed at various levels, from transcriptional to translational level. The translational control is widely used to regulate gene expression, especially when a rapid, local, and selective control over protein synthesis is required. The present review describes instructive examples of translational regulation in yeast, together with regulatory elements within mRNAs. The review also outlines the important contributions of mRNAbinding proteins that act in harmony with several translational elements to generate appropriate translational signals and responses. More >
