Dong G et al. discovered that F-box and leucine-rich repeat protein 19 antisense RNA 1 (FBXL19-AS1) is a lncRNA and serves as an oncogene in breast cancer via miR-876-5p/FOXM1 axis: miR-876-5p was reported as a tumor suppressor which represses the expression of FOXM1 [163,164], and FBXL19-AS1 overexpression circumvents the function of miR-876-5p via directly absorbing it in the cytoplasm, thereby upregulating the expression of FOXM1 to induce breast cancer [50]. This evidence concerns the gene PTGDR and neoplasm.
