miRNA (micro-RNA) arrays can detect mature miRNAs and differentiate highly similar miRNA molecules. It is widely used for detecting and comparing the expression status of microRNAs in different samples and for analyzing the target genes they regulate.
Overview of miRNA
The microRNA, often known as miRNA, is a vast family of RNA molecules that are around 22 nucleotides long and are widely expressed in eukaryotic organisms. There are at least hundreds of microRNAs that are encoded in complex genomes. These microRNAs are principally responsible for inhibiting the expression of the target post-transcriptional gene. A growing body of evidence suggests that microRNAs play crucial roles in normal cellular processes (differentiation, proliferation, and cell death) and the stress response. This evidence also suggests that microRNAs are involved in developing cancer and other pathological conditions. Because of this, microRNAs have the potential to act as a diagnostic and prognostic tool for illnesses. Therefore, it is necessary to have a solid understanding of the expression of miRNAs as well as their functions in a variety of diverse environments.

Functions of miRNA
The RNA-induced silencing complex is responsible for miRNAs' regulatory actions (RISC). MiRNA forms complexes with RISC, activating the complex to target messenger RNA (mRNA) designated by miRNA. Numerous models of RISC assembly have been presented, and researchers continue to investigate the mechanisms of RISC loading and activation. The degree and form of complementarity between the miRNA and its target dictate the gene silencing mechanism, slicer-dependent mRNA degradation, or slicer-independent translation inhibition.

| Abstract | Biomedical research often uses the Rag2 knockout (KO) mouse. The immunologically impaired state concurrently affects several signaling channels and molecules, including miRNAs and mRNA transcripts that are engaged in essential biological activities. In addition, miRNAs and transcripts are interdependent, often creating a feedback loop; dysregulation in one can influence the expression of the other, and both participate in many physiological processes including immune control. They present a comprehensive dataset comparing Rag2 KO mice to wild-type mice in miRNA and mRNA expression. The miRNA and mRNA expression profiles were obtained from whole RNA using a miRNA expression microarray or a BeadChip microarray, respectively. Hence, this dataset will offer the framework for a comparative examination of the miRNAs and mRNAs that are dysregulated in Rag2 KO mice. The results should reveal how miRNAs regulate immune function and interact with mRNAs in Rag2 KO mice. |
| Result |
The expression of twenty-eight microRNAs and 936 genes varied by at least twofold between Rag2 KO mice and their wild-type counterparts. qRT-PCR was used to check the expression of these differentially expressed miRNAs and genes in order to verify the validity of these microarray studies. For these experiments, a second group of Rag2 KO and wild-type mice were employed; these mice were maintained and grown under the same experimental circumstances as the animals used for the microarray analysis of miRNA expression and the BeadChip microarray analysis.

Our miRNA Array Services
Real-time PCR, microarrays, and deep sequencing have been used extensively to profile miRNA expression. Among these, the miRNA microarray technique is widely utilized since it is high throughput, generally less expensive, and most of the experimental and analysis steps can be performed in the molecular biology laboratories of the majority of universities, medical schools, and affiliated institutions. However, the prefabricated miRNA microarray cannot suit the individual needs of researchers doing an in-depth analysis of miRNAs. As a renowned biotechnology firm, Creative Biolabs possesses vast knowledge and experience that enables it to deliver unique and tailored miRNA microarray services.
