This study aimed to systematically evaluate the value of combined detection of serum CEA and CA125 concentrations for the diagnosis of lung cancer. Related studies regarding the diagnosis of lung cancer were searched in PubMed, Embase, CNKI, and Wanfang using a computer. The number of patients who were true-positive, false-positive, false-negative, and true-negative were extracted from each study. Meta-analysis was performed using the Meta-Disc l.4, RevMan 5.3. Seven studies involving 2,216 cases were finally included...

Based on the exciting insights gleaned from decades of ground-breaking research, it has become evident that deregulated signaling pathways play instrumental role in cancer development and progression. Interestingly discovery of non-coding RNAs has revolutionized our understanding related to transcription, post-transcription and translation. Modern era has witnessed landmark discoveries in the field of molecular cancer and non-coding RNA biology has undergone tremendous broadening. There has been an exponential growth in the list of publications related to non-coding RNAs and overwhelmingly increasing classes of non-coding RNAs are adding new layers of complexity to already complicated nature of cancer...

Circular RNAs(circRNA) are recently demonstrated to have a close relationship with tumors.To investigate the role of circular RNA in the pathogenesis of salivary adenoid cystic carcinoma(SACC), ten SACC tissues and paired normal submandibular gland(SMG) tissues were collected as the tumor group and the control group. Total RNA was extracted and then measured using ceRNA microarray (including mRNA, lncRNA, and circRNA) and miRNA microarray. Gene Ontology(GO) analysis and Kyoto Encyclopedia of Gene and Genomes (KEGG) pathway analysis were performed in order to investigate the function of the differential expressing genes...

Prevalence of neural tube defect (NTD) has reduced after folic acid intake. However; which mechanisms are effective in NTD are not known exactly. In this study; due to the possible effects on hypoxic pathway and embryonic development, particularly on extracellular matrix components, Hif-1α Pro582Ser and TGF-β3 IVS5+104 A/G SfaN1 polymorphisms were studied by PCR-RFLP method both on children with NTDs and mothers. Statistical differences were seen for Hif-1α and TGF-β3 IVS5+104 A/G SfaN1 polymorphisms in children with NTDs but no difference was seen in mothers...

We investigated the effects of Leontice leontopetalum and Bongardia chrysogonum on apoptosis, gamma-aminobutyric acid (GABAA) receptor positive cell number, cyclin-B1 and bcl-2 levels and oxidative stress in pentylenetetrazol (PTZ) kindling in rats. Kindling was produced by subconvulsant doses of PTZ treatments in rats. Wistar albino rats were divided into 4 groups; Control, PTZ treated (PTZ), PTZ+L. leontopetalum extract treated (PTZ+LLE) and PTZ+B. chrysogonum extract treated (PTZ+BCE) groups.

Acquired drug resistance is one of the main limitations in pharmacological therapy of malignancies including gastric cancer. MicroRNAs (miRNAs) are a class of small noncoding RNAs that suppress their targets by binding to the 3'UTR region of genes. In this study, we explored investigate the target gene of miR-494 and its roles in chemoresistance of gastric cancer. We found that miR-494 was significantly down-regulated in gastric cancer cells lines compared to the normal gastric epithelial cell line. Exogenous overexpression of miR-494 increased the chemosensitivity of gastric cancer cells to doxorubicin...

Fang Han, Guoqiang Liu, Caifeng Sun, Jienan Wei
Multidrug resistance (MDR) poses a great impediment to cancer treatment. Excessive expression of ATP-binding cassette transport protein AC-1 (P-glycoprotein, P-GLP) is usually involved in MDR. In this study, ailanthone (AIL), a natural compound extracted from the whole seedlings of Ailanthus altissima (Simaroubaceae) was shown to mediate the reversal of P-GLP-induced MDR and restore the susceptibility of K562/A02 cells to doxorubicin (DOX). Further mechanistic studies revealed that AIL increased intracellular DOX accumulation and interrupted Rh123 efflux through suppression of P-GLP, and also suppressed P-GLP ATPase activity...

Clinical and experimental studies show that epilepsy affects cardiac function; however, the underlying molecular mechanism has not been fully elucidated. Inwardly-rectifying potassium (Kir) channels transport K+ ions into excitable cells such as neurons and cardiomyocytes; they control the cell excitability by acting towards the repolarization phase of cardiac action potential. Kir channel expression has been previously shown to vary in epileptic brains, at the same time seizures are known to affect the autonomic nervous system...

Neurotrophic factors are growth factors that promote neuronal survival, regulate synaptic function and neurotransmitter release, and promote the plasticity and growth of axons in the peripheral and central nervous systems. This study focused on the roles of nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) in the survival of adult dorsal root ganglion (DRG) neurons following axotomy. To investigate this, we cultured adult mouse DRG neurons and administered NGF or BDNF to the culture medium at different doses before transection...

Many plant species produce phenolic compounds in their various organs and their use in crop protection. These plant secondary metabolites may serve as toxins against the insect pests. The objective of this study was to evaluate in vitro the bio-insecticidal effect of an aqueous extract of wild Olive leaves on Psylla larvae (Euphyllura olivina), a primary pest of the cultivated Olive tree (Olea europaea L. subsp sativa). Two concentrations of 0.05g/ml and 0.1g/ml leaves grinding powder in distilled water were sprayed on branches infested with Psylla larvae...

To characterize the associations between the cleft palate (CPO) and single nucleotide polymorphisms (SNPs) of special AT-rich sequence-binding protein 2 (SATB2). We recruited 241 CPO and performed a case-control study with 242 controls. Concurrently, 103 of the patients and their normal parents were recruited to perform a case-parent trio study. Sixteen selected SNPs were genotyped. Furthermore, A meta-analysis was used to enhance the robustness of our conclusions. The case-control study provided no support for the hypothesis that any of the 16 selected SNPs played a significant role in CPO...

CRISPR/Cas9 is a technology evolved from modified type II immune system of bacteria and archaea. Exploitation of this bacterial immune system in all eukaryotes including plants may lead to site-specific targeted genome engineering. Genome engineering is objectively utilized to express/silence a trait harbouring gene in the plant genome. In this review, different genetic engineering techniques including classical breeding, RNAi and genetic transformation and synthetic sequence-specific nucleases (zinc finger nucleases; ZFNs and transcription activator-like effector nuclease; TALENs) techniques have been described and compared with advanced genome editing technique CRISPR/Cas9, on the basis of their merits and drawbacks...
