Some microRNAs have carcinogenic or tumor suppressive effects in breast cancer, which is the most common cancer in women worldwide. MiR-7 and miR-9 are tumor suppressor microRNAs, which induce apoptosis and inhibit proliferation in breast cancer cells. Moreover, miR-96 and miR-182 are onco-microRNAs that increase proliferation, migration, and tumorigenesis in breast cancer cells. This study aimed to identify the direct target genes of these four microRNAs in the human breast cancer cell lines MCF-7 and MDA-MB-231...

The traditional scale invariant feature transform (SIFT) method can extract distinctive features for image matching. However, it is extremely time-consuming in SIFT matching because of the use of the Euclidean distance measure. Recently, many binary SIFT (BSIFT) methods have been developed to improve matching efficiency; however, none of them is invariant to mirror reflection. To address these problems, in this paper, we present a horizontal or vertical mirror reflection invariant binary descriptor named MBR-SIFT, in addition to a novel image matching approach...

Estimating interactions between physiological systems is an important challenge in modern biomedical research. Here, we explore a new concept for quantifying information common in two time series by cross-compressibility. Cross-compression entropy (CCE) exploits the ZIP data compression algorithm extended to bivariate data analysis. First, time series are transformed into symbol vectors. Symbols of the target time series are coded by the symbols of the source series. Uncoupled and linearly coupled surrogates were derived from cardiovascular recordings of 36 healthy controls obtained during rest to demonstrate suitability of this method for assessing physiological coupling...

Mammalian T7 polymerase-based cytoplasmic expression systems are common tool for molecular studies. The majority of these systems include the internal ribosome entry site (IRES) of the encephalomyocarditis virus (EMCV). To carry out a cap-independent translation process, this type of IRES might require the expression of an extensive array of host factors, what is a disadvantage. Other IRESes might be less dependent on the host cell factors, but their biology is characterized to a lesser degree. Here, we compare the translational efficiencies of bovine viral diarrhea virus (BVDV) IRES with that of ECMV...

T-cell lymphoblastic lymphoma (T-LBL) is an aggressive malignancy with poor prognosis and high recurrence rate. Long non-coding RNA (lncRNA)-MEG3 is an important tumor suppressor in various cancers. The present study investigated the potential role of maternally expressed gene 3 (MEG3) in the progression of T-LBL. Suppressed expression of MEG3 was detected in T-LBL tissues compared with adjacent histologically normal tissues. Down-regulated level of MEG3 was also found in three T-LBL cell lines (CCRF-CEM, Jurkat and SUP-T1) compared with human T-cell line H9...

Clostridium cellulovorans 743B, an anaerobic and mesophilic bacterium, produces an extracellular enzyme complex called the cellulosome on the cell surface. Recently, we have reported the whole genome sequence of C. cellulovorans, which revealed that a total of 4 cellulosomal scaffolding proteins: CbpA, HbpA, CbpB, and CbpC were encoded in the C. cellulovorans genome. In particular, cbpC encoded a 429-residue polypeptide that includes a carbohydrate-binding module (CBM), an S-layer homology module, and a cohesin...

Vast numbers of proteins work cooperatively to exert their functions in various cells. In order to understand the functions and molecular mechanisms of these proteins in plants, analyses of transgenic plants that concomitantly express two protein-coding genes are often required. We developed a novel Gateway cloning technology-compatible binary vector system, the R4 dual-site (R4DS) Gateway cloning system, which enables the easy and efficient cloning of two desired sets of promoters and open reading frames (ORFs) into a binary vector using promoter and ORF entry clones...

The design and generation of an optimal expression construct is the first and essential step in in the characterization of a protein of interest. Besides evaluation and optimization of process parameters (e.g. selection of the best expression host or cell line and optimal induction conditions and time points), the design of the expression construct itself has a major impact. However, the path to this final expression construct is often not straight forward and includes multiple learning cycles accompanied by design variations and retesting of construct variants, since multiple, functional DNA sequences of the expression vector backbone, either coding or non-coding, can have a major impact on expression yields...

Endometrial carcinoma is a complex disease characterized by both genetic, epigenetic and environmental factors. Increasing evidence has suggested that long non-coding RNAs (lncRNAs) play important roles in the development and progression of cancers. In this study, we performed a comparison analysis for lncRNA expression between patients with early-stage (stage I/II) and those with advanced-stage (stage III/IV) derived from The Cancer Genome Atlas (TCGA) project and identified 17 differentially expressed lncRNAs using student t-test...

Local Zika virus transmission in the United States involving one or both of the known vector species, Aedes aegypti and Ae. albopictus, is of major concern. To assist efforts to anticipate the risks of transmission, we developed an Excel spreadsheet tool that uses vector and virus temperature thresholds, remotely sensed maximum temperature, and habitat suitability models to answer the questions: "is Zika transmission likely here?" and "when should we conduct vector surveillance?" An example spreadsheet, updated regularly and freely available, uses near real-time and forecast temperature data to generate guidance, based on a novel four level Zika risk code, for 733 US military facilities in the 50 states, the District of Columbia, and the territories of Guam and Puerto Rico...

BACKGROUND: The mosquito Aedes aegypti is the primary vector for medically important arthropod-borne viruses, including chikungunya virus (CHIKV). Following oral acquisition, an arbovirus has to persistently infect several organs in the mosquito before becoming transmissible to another vertebrate host. A major obstacle an arbovirus has to overcome during its infection cycle inside the mosquito is the midgut escape barrier, representing the exit mechanism arboviruses utilize when disseminating from the midgut...

Rickettsia rickettsii is a tick-borne obligate intracellular bacterium that causes Rocky Mountain Spotted Fever (RMSF). In Brazil, two species of ticks in the genus Amblyomma, A. sculptum and A. aureolatum, are incriminated as vectors of this bacterium. Importantly, these two species present remarkable differences in susceptibility to R. rickettsii infection, where A. aureolatum is more susceptible than A. sculptum. In the current study, A. aureolatum and A. sculptum ticks were fed on suitable hosts previously inoculated with R...

There is growing evidence from animal and human studies that demonstrate that acquired paternal traits can impair both a male's fertility and the health of his offspring, including advanced age, smoking, stress, trauma, under-nutrition, infection, toxin exposure, and obesity. Curiously, many of these factors manifest as impaired neurological, behavioural, and/or metabolic functioning in offspring. The underlying molecular mechanisms that respond to the paternal environment and act as vectors of intergenerational transmission are beginning to emerge...

To make the problem of multilabel classification with many classes more tractable, in recent years, academia has seen efforts devoted to performing label space dimension reduction (LSDR). Specifically, LSDR encodes high-dimensional label vectors into low-dimensional code vectors lying in a latent space, so as to train predictive models at much lower costs. With respect to the prediction, it performs classification for any unseen instance by recovering a label vector from its predicted code vector via a decoding process...

Over the last decades, gene therapy has emerged as a pioneering therapeutic approach to treat or prevent several diseases. Among the explored strategies, the short-term silencing of protein coding genes mediated by siRNAs has a good therapeutic potential in a clinical setting. However, the widespread use of siRNA will require the development of clinically suitable, safe and effective vehicles with the ability to complex and deliver siRNA into target cells with minimal toxicity. Lately, dendrimers have gained considerable attention as non-viral vectors in nucleic acid delivery due to their unique structural characteristics (globular, well defined and highly branched structure, multivalency, low polydispersity and tunable nanosize), along with their relevant capacity to complex and protect nucleic acids in compact nanostructures, which can be functionalized with targeting moieties in order to get cell specificity...

Chitinases function in the digestion of chitin molecules, which are present principally in insects and fungi. In plants, chitinase genes play important roles in defense, and their expression can be triggered in response to both biotic and abiotic stresses. In this study, we cloned and characterized an endochitinase (VDECH) from Verticillium dahliae, strain Vd080. The VDECH coding region consists of 1845bp with two exons and one 54bp intron, encoding a 615 amino acid protein with the predicted molecular weight (MW) of 63...

Recent reports have indicated that small RNAs have key roles in the response of the E.coli to stress and also in the regulating of virulence factors. It seems that some small non-coding RNAs are involved in multidrug resistance. Previous studies have indicated that rprA can increase the tolerance to Kanamycin in RcsB-deficient Escherichia coli K-12 following osmotic shock. The current study aims to clone and over-express the non-coding RNA rprA in E.coli and investigate its effect on the bacterial resistance to Kanamycin without any osmotic shock...

Using proper signal peptide and codon optimization are important factors that must be considered when designing the vector to increase protein expression in Chinese Hamster Ovary (CHO) cells. The aim of the present study is to investigate how to enhance Pertuzumab production through heavy and light chain coding gene optimization and proper signal peptide selection. First, CHO-K1 cells were transiently transfected with whole-antibody-gene-optimized, variable-regions-optimized and non-optimized constructs and then we employed five different signal peptides to improve the secretion efficiency of Pertuzumab...
