Hierarchical clustering is a commonly used and valuable approach in clustering analysis. However it depends on the measure used to assess similarity between samples. Two frequently adopted distance measures are Euclidean distance (L<sub>2</sub>- norm) and city-block distance (L<sub>1</sub>-norm), and they do not take into account special characteristics of data at hand. In this paper, considering the nonnegativity of gene expression ...

Microarray is one of the most promising tools available for researchers in the life sciences to study gene expression profiles. Through microarray analysis, gene expression levels can be obtained, and the biological information of a disease can be identified. The gene expression information embedded in the microarray is extracted using image-processing techniques. Gridding is one of the important processes used to extract features in DNA microarray, by assigning each spot in the microarray with individual coordinates for further data interpretation. This paper evaluates popular techniques of DNA microarray image gridding in the literature with an emphasis on gridding accuracy, speed, and the ability to remove noise. Based on our evaluation, the Otsu method can provide a better performance in terms of processing speed, accuracy, and ability to remove noise compared to other methods discussed in this paper.
Nrf1 [p45 nuclear factor-erythroid 2 (p45 NF-E2)-related factor 1], a member of the CNC bZIP (CNC basic region leucine zipper) family, is known to be a transcriptional activator by dimerization with its distinct partners, such as Maf, FosB, c-Jun, JunD, etc. The transcriptional roles of CNC-bZIP family are demonstrated to be involved in globin gene expression as well as the antioxidant response. MCRS2, a protein with transforming, nucleolar sequestration, ribosomal gene regulation, as well as telomerase inhibition activities, was identified as a novel interacting protein of Nrf1. In this study, we find that ERK1/2 phosphorylates Nrf1 during the interaction between Nrf1 and MCRS2. The phosphorylation of Nrf1 is induced by MCRS2 among the interactions between MCRS2 and Nrf1.
Cell surface molecule CD44 of human brain microvascular endothelial cells (HBMEC) is the receptor of Cryptococcus neoformans during the infection. We performed microarray analysis and used principle component analysis to examine gene profiles of HBMEC in responses to C neoformans infection. The CD44 levels increases, peaking at the 4-hour time point and then declined gradually. Seventy genes displayed a similar gene profile. Our results showed a dynamic relationship between pathogen-host interactions. The data is useful for the analysis of invasion mechanism of C neoformans into HBMEC.
In the field of wound healing research non-thermal plasma (NTP) has attracted increasing attention over the last decades. NTP has a complex composition and consists of ions, exited atoms, electrons, ultraviolet (UV) light, visible and infrared radiation, neutral molecules, and free radicals e.g. reactive oxygen and nitrogen species (ROS/RNS)<sup>1</sup>. Next to its well-established antibacterial effects it has potential proliferation promoting properties on eukaryotic cells<sup>2</sup>. Although a number of studies have been carried out to investigate the impact of NTP on human cells, not much is known about the influences on the molecular level. In order to shed some light in the complex impact NTP has on wound healing, this study analyzed in detail the differential gene expression pattern of human cells involved in this process in response to NTP treatment. Besides the keratinocyte cell line HaCaT, two immune cells lines were studied - the CD4<sup>+</sup> T helper cell line Jurkat and the monocyte cell line THP-1.
Hierarchical clustering is a commonly used and valuable approach in clustering analysis. However it depends on the measure used to assess similarity between samples. Two frequently adopted distance measures are Euclidean distance (L<sub>2</sub>- norm) and city-block distance (L<sub>1</sub>-norm), and they do not take into account special characteristics of data at hand. In this paper, considering the nonnegativity of gene expression data, we apply a generalized Kullback-Leibler (KL) divergence to measure the similarity in hierarchial clustering analysis. Experimental results on several real cancer related gene expression datasets show that the proposed KL divergence outperforms both L<sub>2</sub> and L<sub>1</sub> distances.
Hidden Markov models (HMMs) have demonstrated great successes in modeling noisy sequential data sets in the area of speech recognition and protein sequence profiling. Results from association test showed significant Markov dependency in time-series gene expression data, and therefore HMMs would be especially appropriate for modeling gene expressions. In this project, we developed a gene function prediction tool based on profile HMMs. Each function class is associated with a distinct HMM whose parameters are trained using yeast time-series gene expression data. The function annotations of the HMM training set were obtained from Munich Information Centre for Protein Sequences (MIPS) data base. We designed several structural variants of HMMs (single, double-split) and tested each of them on forty function classes each of which includes more than one hundred instances. The highest prediction sensitivity we achieved is 51% by using double-split HMM with 3-fold cross- validation.
There is growing interest in using rank-ordered gene lists to avoid excessive dependence on measured gene expression levels, which can vary strongly across experiments, platforms, or analysis methods. As a useful tool for working with these lists, this paper describes two extensions of an ordered list comparison measure, recently proposed for comparing Internet search engines: the use of random permutations to assess the significance of differences between ordered lists, and a graphical extension that highlights the items responsible for the main differences between two lists. The method is illustrated for a prostate cancer example from the genomics literature.
In the past years, microarray technologies have become a central tool in biological research. The extraction or identification of gene groups with similar expression pattern plays an important role in the analysis of genes. Besides traditional clustering methods, biclustering is also being used to analyze biological datasets due to its ability to group both genes across conditions simultaneously. The paper presents a comparison of advanced with the traditional tools for biological data extraction. This paper compares different clustering and biclustering approaches used to analyze DLBCL (diffuse large B-cell lymphoma) microarray dataset. The algorithms were compared on the grounds of enrichment values with support from runtime analysis. Typical annotations for the analyzed list of genes can be well understood using the BicAT toolbox. The paper explains in detail the intellects affecting the enrichment values, leading to the best technique for the dataset mentioned above.
Studies about the variation of DNA methylation pattern under high temperature stress (37°C) contribute to a comprehensive understanding of the apparent regulation of biological functions. Based on the in vitro cultivation of genetically modified birch (_Betula platyphylla_Suk.) clones for high- temperature stress, the paper detected exogenous gene transcription level differences with RT-PCR. Methylation-sensitive amplified polymorphism (MSAP) analysis the variation of DNA methylation pattern in transgenic birch. In this paper we used ten pairs of primers MSAP to deal with genetically modified DNA screening birch. The study revealed that high temperature stress can lead the level of transcriptional expression of transgene decrease, while endogenous levels of DNA methylation, including the overall methylation, the lateral semi-cytosine methylation as well as the inside of cytosine methylation level of the whole is almost twice than the control.
Rotator cuff tears are among the most common shoulder injuries that require surgery. High failure rates of biological graft-based repairs underscore the need for functional alternatives. Specifically, functional grafts must incorporate the gradient of mineralization from tendon to bone in order to be biomimetic. In this study, effects of varying concentrations of mineral content in aligned nanofiber scaffolds on human mesenchymal stem cells (hMSC) are evaluated. It is hypothesized that mineral content will regulate cell response, matrix deposition, and integrin gene expression. hMSC were seeded on aligned nanofiber scaffolds of polylactide-co-glycolide with 0%, 10%, and 15% hydroxyapatite content, and were maintained in chondrogenic medium. Cell proliferation (n=5), collagen deposition (n=5), and gene expression (n=5) for Collagen X, Sox9, osteopontin, osteonectin, and osteocalcin were determined over 42 days. Cell number was found to differ between the non-mineralized and mineralized groups. Significant increase in collagen deposition over time was observed in mineralized scaffold groups, and the 15% group showing significantly higher deposition than the 0% group by day 42. Lower expressions of chondrocyte hyperotrophy marker Collagen X and chondrogenic marker Sox9 and maintained high expressions of osteogenic markers osteopontin, osteonectin, and osteocalcin suggest an osteogenic lineage for the stem cells. In conclusion, addition of HA particles influenced hMSC proliferation, matrix deposition, and may induce an osteogenic differentiation response from the stem cells.
