Long non-coding RNAs (lncRNAs) play critical roles in regulating cell signaling pathways in cancer. Recent studies have shown that lncRNAs can influence gene expression through various mechanisms, including transcriptional and post-transcriptional regulation, chromatin modification, and protein interaction. They can act as scaffolds to recruit proteins, regulate alternative splicing, and modulate mRNA stability and translation. LncRNAs are involved in key signaling pathways such as p53, NF-κB, PI3K/AKT, and Notch, which are crucial for cancer development and progression. In the p53 pathway, lncRNAs can regulate p53 expression and stability, either by enhancing or suppressing its activity. For example, Linc-RoR can both induce and suppress p53, depending on the cellular context. LncRNAs also interact with p53 to modulate its transcriptional activity and influence downstream gene expression. In the NF-κB pathway, lncRNAs such as NKILA and Lethe can regulate NF-κB activity by interacting with its components, either by inhibiting or enhancing its signaling. LncRNAs can also act as scaffolds to recruit proteins involved in NF-κB signaling, thereby modulating its activity. In the PI3K/AKT pathway, lncRNAs such as AK023948 and LINK-A can regulate AKT activity by interacting with key components of the pathway, including PI3K and AKT. These lncRNAs can either promote or inhibit AKT signaling, which is essential for cell proliferation and survival. In the Notch pathway, lncRNAs such as LUNAR1 and TUG1 can regulate Notch signaling by modulating the expression of genes involved in stem cell maintenance and tumor progression. LncRNAs have been shown to promote or suppress tumor growth by regulating various signaling pathways. For example, MALAT1 and HOTAIR are associated with cancer progression by promoting metastasis and tumor growth. Conversely, some lncRNAs, such as GAS5 and Loc285194, act as tumor suppressors by inhibiting cancer cell proliferation and metastasis. The regulation of lncRNAs in these pathways highlights their importance in cancer biology and their potential as therapeutic targets. Overall, lncRNAs are critical regulators of cell signaling pathways in cancer, influencing various aspects of tumorigenesis. Their ability to interact with signaling molecules and modulate gene expression makes them important players in cancer development and progression. Further research is needed to fully understand the complex roles of lncRNAs in cancer and to develop targeted therapies based on their functions.Long non-coding RNAs (lncRNAs) play critical roles in regulating cell signaling pathways in cancer.
