Bioinformatic Evaluation of the MiR-5011 Effect On the Crutial Genes That Involved in Colorectal Cancer

Zahra Bayat, Bahram Mohamad Soltani
Abstract

Introduction: The microarray technique has been established as the reference method for studying the genes that are in the control of miRNAs. However, the high cost of this method has hampered its use in most research centers. On the other hand, the improvement of the bioinformatical algorithms and computer modeling systems has led to the development of the bioinformatical softwares that can predict mRNA targets for miRNAs. Therefore, the aim of this theoretical study was bioinformatically evaluation of the effect of miR-5011 on genes that can be involved in colorectal cancer, by using various specific softwares.

Methods/Materials: By Using different algorithms in TargetScan, DIANA and miRWalk databases, the potential gene targets of miR-5011 were identified. Then, a score table from the candidate genes was prepared based on the affinity of the seed region of miR-5011 and the number of MRE in the 3`-UTR region of genes. Finally, genes with highest scores were chosen as the candidates for practical analysis.

Results: The results of the bioinformatical‌ analysis showed that SMAD6 and SMAD7 genes in TGFB signaling pathway and WNT3A and LRP6 genes in WNT signaling pathway are the most potential genes that might be affected by miR-5011 in colorectal cancer.

Discussion: It seems that WNT3A, LRP6, SMAD6 and SMAD7 suppressed by miR-5011 and this microRNA maybe act as a tumor suppressor and downregulated in colorectal cancer, Therefore this microRNA and its target genes can be considered as a suitable new candidate for experimental evaluation.

Entomology and Applied Science Letters is an international double-blind peer reviewed publication which publishes scientific research & review articles related to insects that contain information of interest to a wider audience, e.g. papers bearing on the theoretical, genetic, agricultural, medical and biodiversity issues. Emphasis is also placed on the selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance. In addition to full-length research articles and reviews, the journal publishes interpretive articles in a Forum section, Short Communications, and Letters to the Editor. The journal publishes reports on all phases of medical entomology and medical acarology, including the systematics and biology of insects, acarines, and other arthropods of public health and veterinary significance.

Entomology and Applied Science Letters supports the submission of entomological papers that contain information of interest to a wider reader groups e. g. papers bearing on taxonomy, phylogeny, biodiversity, ecology, systematic, agriculture, morphology. The selection of comprehensive, revisionary or integrated systematics studies of broader biological or zoogeographical relevance is also important. Distinguished entomologists drawn from different parts of the world serve as honorary members of the Editorial Board. The journal encompasses all the varied aspects of entomological research.
