Abstract
Lupus nephritis (LN) is a serious problem that results from systemic lupus erythematosus (SLE) complications. Recent studies have highlighted that non-coding RNA (ncRNA) dysregulation is a notable feature in patients with SLE. As a result, this research was designed to investigate lncRNA CASC2 and miR-155 levels as non-invasive diagnostic biomarkers in SLE patients, including those with and without nephritis, and to investigate their effectiveness in assessing disease severity and predicting LN. Our study included 60 patients with SLE who were subclassified into (30 non-LN and 30 LN groups), along with 30 control subjects. Quantification of lncRNA CASC2 and miR-155 in serum samples from the Egyptian population was carried out with real-time polymerase chain reaction (RT-PCR). The disease activity index (SLEDAI) for SLE was evaluated, and the analysis of the receiver operating characteristic (ROC) curve was implemented. Increased levels of lncRNA CASC2 were observed in SLE patients compared to healthy controls, with even higher levels observed in the LN group versus the non-LN patients' group. Conversely, miR-155 was noted to be down-regulated in SLE patients relative to controls, and its levels were lower in the LN group relative to the non-LN patients' group. The elevated expression of lncRNA CASC2 and reduced expression of miR-155 were both correlated to the severity of the disease. The current study illustrated that both lncRNA CASC2 and miR-155 could act as valuable non-invasive diagnostic biomarkers for SLE and predicting LN among SLE patients, as well as their abilities to detect the disease severity and progression.
