After evaluating the expression of multiple lncRNAs in blood samples of untreated BC patients, Pourramezan et al. identified that UCA1 was significantly upregulated in BC patients compared to healthy women; however, the correlation between UCA1 levels and clinicopathological characteristics, such as race, histological grade, tumor size, TNM staging, and molecular subtypes, was not statistically significant [30]. This evidence concerns the gene UCA1 and breast cancer.
