Abstract
- Objective: MicroRNAs are fine regulators for gene expression during the post-transcriptional stage in many autoimmune diseases. HypoxamiRs (miR-210 and miR-21) play an important role in hypoxia and in inflammation-associated hypoxia. Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune disease that would potentiate many pathological complications, including hemolytic anemia. This study aimed to investigate the role of hypoxamiRs in SLE/hemolytic anemia patients.<br />Methods: This work was designed to analyze the circulating levels of↱ the miR-210 and miR-21 expressions and hypoxia-inducible factor-1α (HIF-α) in SLE/hemolytic anemia patients. SLE activity was evaluated for all patients by SLE Disease Activity Index (SLEDAI). Clinical manifestations/complications and serological/hematological investigations were reported. HIF-α concentration was assayed by ELISA and expression of miR-21 and miR-210 was analyzed by qRT-PCR.<br />Results: The results indicated that the fold change of the miR-210/miR-21 expressions in plasma was significantly elevated in SLE/hemolytic anemia patients. A strong positive correlation between the miR-210 and miR-21 expression levels was also recorded. Among the associated-disease complications, hypertension, arthritis, oral ulcers, and serositis were associated with a high circulating miR-210 expression, while the occurrence of renal disorders was associated with the increased miR-21 expression. Furthermore, the HIF-α level was remarkably elevated in SLE/hemolytic anemia patients. A high positive correlation was recorded between the HIF-α concentration and miR-210/miR-21 expression levels. The occurrence of oral ulcers, arthritis, and hypertension was associated with the increased HIF-α concentration. On the other hand, SLEDAI and white blood cell count were positively correlated with miR-21/ miR-210. The erythrocyte sedimentation rate was positively correlated with miR-21.<br />Conclusion: The dysregulation of the circulating miR-210/miR-210/HIF-1α levels in SLE/hemolytic anemia patients advocated that the hypoxia pathway might have an essential role in the pathogenesis and complications of these diseases.<br /> (© 2022.
