Abstract:
LncRNAs and miRNAs are the two most important non-coding RNAs, which have been identified to be associated with cancer progression or prevention. The dysregulation of lncRNAs conducts tumorigenesis and metastasis in different ways. One of the mechanisms is that lncRNAs interact with miRNAs to regulate distinct cellular and genomic processes and cancer progression. LncRNA SNHG7 as an oncogene sponges miRNAs and develops lncRNA-miRNA-mRNA axes, leading to the regulation of several signaling pathways such as Wnt/β-Catenin, PI3K/AKT/mTOR, SIRT1, and Snail-EMT. Therefore, in this article, after a brief overview of lncRNA SNHG7-miRNA-mRNA axes' contribution to cancer development, we will discuss the role of lncRNA SNHG7 in the genes expression and signaling pathways related to cancers development via acting as a ceRNA.
Insights
Long non-coding RNAs (lncRNAs) like SNHG7 act as oncogenes by sponging microRNAs (miRNAs), influencing cancer development through lncRNA-miRNA-mRNA pathways and key signaling routes.
Area of Science:
- Molecular Biology
- Genetics
- Oncology
Background:
- Long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) are critical non-coding RNAs involved in cancer.
- Dysregulated lncRNAs contribute to tumorigenesis and metastasis through various mechanisms.
- lncRNAs can interact with miRNAs, affecting cellular processes, genomic stability, and cancer progression.
Purpose of the Study:
- To provide an overview of the contribution of lncRNA SNHG7-miRNA-mRNA axes to cancer development.
- To discuss the role of lncRNA SNHG7 in regulating gene expression and signaling pathways in cancer.
- To explore lncRNA SNHG7's function as a competing endogenous RNA (ceRNA).
Main Methods:
- Literature review and analysis of existing research on lncRNA SNHG7.
- Examination of lncRNA-miRNA interactions and their downstream effects.
- Investigation of signaling pathways modulated by lncRNA SNHG7, including Wnt/β-Catenin, PI3K/AKT/mTOR, SIRT1, and Snail-EMT.
Main Results:
- LncRNA SNHG7 functions as an oncogene by sponging miRNAs.
- SNHG7 participates in the formation of lncRNA-miRNA-mRNA axes.
