Expression and crucial role of long non-coding RNA FGD5-AS1 in human cancers.

Long non-coding RNAs (lncRNAs) are transcribed by RNA polymerase II and are longer than 200 nucleotides. Several studies have revealed that lncRNAs are important regulators of cancer progression. The lncRNA FGD5-AS1, first identified in 2018, has emerged as a crucial regulator of processes related to carcinogenesis. The expression levels of FGD5-AS1 are known to be significantly up-regulated in a variety of human cancers. Moreover, FGD5-AS1 expression closely correlates with clinical features and poor prognosis and its expression has been shown to attenuate cell proliferation, cell migration, cell invasiveness, drug resistance, and the epithelial-mesenchymal transition through several pathways. Here, we provide an overview of the role of FGD5-AS1 in various cancers and discuss its potential clinical utility in tumor progression. In addition, we used a gene expression profiling interactive analysis dataset to explore associations between FGD5-AS1 pan-cancer expressions and prognoses.
