Abstract: 

THE INTERACTIONS BETWEEN ProteinS OF A LIVING CELL ARE IMPORTANT FOR ITS BIOLOGICAL FUNCTIONS AND DETERMINING THESE INTERACTIONS PROVIDE VALUABLE INFORMATION ABOUT HOW DO BIOLOGICAL SYSTEMS WORK. REGARDING THE IMPORTANCE OF THE Protein-Protein INTERACTIONS (PPI), IN ONE HAND SEVERAL EXPERIMENTAL TECHNIQUES HAVE BEEN DEVELOPED TO DETECT THE PPIS AND ON THE OTHER HAND, COMPUTATIONAL METHODS TRY TO PREDICT THESE INTERACTIONS VIA MUCH CHEAPER AND FASTER WAYS. THE sequence OF A Protein IS ONE OF THE MOST AVAILABLE INFORMATION AND SO, IT HAS BEEN USED BY SEVERAL COMPUTATIONAL APPROACHES TO PREDICT THE PPIS. IN THIS STUDY, WE USED N-GRAM ENCODING APPROACH TO TRANSFORM THE sequenceS INFORMATION OF ProteinS INTO FEATURE VECTORS. AFTER CONCATENATING THE VECTORS OF ALL Protein PAIRS, A RELAXED VARIABLE KERNEL DENSITY ESTIMATOR (RVKDE) IS USED AS A MACHINE LEARNING TOOL TO PREDICT THE INTERACTIONS. OUR RESULTS SHOW THAT AMONG N-GRAM ENCODING METHODS, 2-GRAM HAS SUPERIOR PERFORMANCE AND IMPROVES THE PREDICTION RESULTS.

Abstract: 

2Introduction: Human genome consists of the three billion base pairs that has about one percent of genetic variation from one person to another، which determines physical، psychological، and susceptibility to diseases. Among the types of genetic diversity, single nucleotide polymorphisms are one of the most important genetic differences between two people. Single nucleotide polymorphism variation is located in the promoter region, exons، introns، untranslated regions and other Deoxyribonucleic acid (DNA) regions. While variation in the exon region can change susceptibility to diseases depending on whether it changes the Protein structure or affects translation kinetics. Diversity in the promoter region can affect the interaction of genetic and epigenetic elements. Also، variation in the promoter region can affect the DNA methylation status. Polymorphic variation in the intron region can affect Messenger Ribonucleic acid splicing and the function of cis-regulatory elements. Polymorphic variation in the 5' Untranslated region، region causes a change in translation efficiency,، while a change in the 3' Untranslated region binds micro Ribonucleic acids to their position then affects the effects. In some cases، variations in Transfer Ribonucleic acid (tRNA) and Ribosomal ribonucleic acid (rRNA) affect the function of these regulatory cis elements. Conclusion: From a clinical point of view, a deep knowledge of this type of genetic variation can help the treatment process, manage patients and understand the prognosis based on these SNPs. Private or personalized medicine is also fundamentally based on genetic diversity. In this article, it was reviewed the types of single nucleotide genetic variation and presented examples of types of cancer, neurological and immunological diseases.

Abstract: 

IN RECENT YEARS, WE ARE FACED WITH LARGE AMOUNTS OF SPORADIC UNSTRUCTURED DATA ON THE WEB. WITH THE EXPLOSIVE GROWTH OF SUCH DATA, THERE IS A GROWING NEED FOR EFFECTIVE METHODS SUCH AS CLUSTERING TO ANALYZE AND EXTRACT INFORMATION. BIOLOGICAL DATA FORMS AN IMPORTANT PART OF UNSTRUCTURED DATA ON THE WEB. Protein sequence DATABASES ARE CONSIDERED AS A PRIMARY SOURCE OF BIOLOGICAL DATA. CLUSTERING CAN HELP TO ORGANIZE sequenceS INTO HOMOLOGOUS AND FUNCTIONALLY SIMILAR GROUPS AND CAN IMPROVE THE SPEED OF DATA PROCESSING AND ANALYSIS. ProteinS ARE RESPONSIBLE FOR MOST OF THE ACTIVITIES IN CELLS. THE MAJORITY OF ProteinS SHOW THEIR FUNCTION THROUGH INTERACTION WITH OTHER ProteinS. HENCE, PREDICTION OF Protein INTERACTIONS IS AN IMPORTANT RESEARCH AREA IN THE BIOMEDICAL SCIENCES. MOTIFS ARE FRAGMENTS FREQUENTLY OCCURRED IN Protein sequenceS. A WELL-KNOWN METHOD TO SPECIFY THE Protein INTERACTION IS BASED ON MOTIF CLUSTERING. EXISTING WORKS ON MOTIF CLUSTERING METHODS SHARE THE PROBLEM OF LIMITATION IN THE NUMBER OF CLUSTERS. HOWEVER, REGARDING THE VAST AMOUNT OF MOTIFS AND THE NECESSITY OF A LARGE NUMBER OF CLUSTERS, IT SEEMS THAT AN EFFICIENT, SCALABLE AND FAST METHOD IS NECESSARY TO CLUSTER SUCH LARGE NUMBER OF sequenceS. IN THIS PAPER, WE PROPOSE A NOVEL APPROACH TO CLUSTER A LARGE NUMBER OF MOTIFS. OUR APPROACH INCLUDES EXTRACTING MOTIFS WITHIN Protein sequenceS, FEATURE SELECTION, PREPROCESSING, DIMENSION REDUCTION AND UTILIZING BIGFCM (A LARGE-SCALE FUZZY CLUSTERING) ON SEVERAL DISTRIBUTED NODES WITH HADOOP FRAMEWORK TO TAKE THE ADVANTAGE OF MAPREDUCE PROGRAMMING. EXPERIMENTAL RESULTS SHOW VERY GOOD PERFORMANCE OF OUR APPROACH.

Abstract: 

Since methods for sequencing machine learning sequences were not successful in classifying healthy and cancerous Proteins, it is imperative to find a way to represent these sequences to classify healthy and ill individuals with deep learning approaches. In this study different methods of Protein sequence representation for classification of Protein sequence of healthy individuals and leukemia have been studied. Results showed that conversion of amino acid letters to one-dimensional feature vectors in classification of 2 classes was not successful and only one disease class was detected. By changing the feature vector to colored numbers, the accuracy of the healthy class recognition was slightly improved. The binary Protein sequence representation method was more efficient than the previous methods with the initiative of sequencing the sequences in both one-dimensional and two-dimensional (image by Gabor filtering). Protein sequence representation as binary image was classified by applying Gabor filter with 100% accuracy of the Protein sequence of healthy individuals and 98. 6% Protein sequence of those with leukemia. The findings of this study showed that the representation of Protein sequence as binary image by applying Gabor filter can be used as a new effective method for representation of Protein sequences for classification.

Abstract: 

Background and Aims: Hepatitis C Virus infects more than 170 million people globally despite highly effective direct acting antiviral drugs that greatly improved treatment. The Hepatitis C virus envelope glycoProteins E1 and E2 are the major target to induce immune responses. Since, the different aspects of E1 such as its function and structure are still discussed and require further study, in current study critical regions of E1 were evaluated. Materials and Methods: Mutation diversity in these areas was determined using strains that were available in online databanks and authentic software. Furthermore, RT-PCR for E1 was done on HCV-1a positive samples and the sequences were analyzed. The percentage of substitutions, desired and stable residues for mutation in each position were indicated. Results: The integrated results exhibited bNAb epitope (residues 313-328) which is the most conserved epitope in E1 glycoProtein sequence among all genotypes of HCV. Conclusion: These kinds of studies may shed light on identification more binding sites of virus and broadly cross-neutralization of antibodies. Moreover, it may facilitate the modeling of peptides to new antiviral design or boosting the immune response in multi-epitope vaccine studies.
