LINC00641/miR-378a and Their Cross-Talk with TNF-α/IFN-γ as Potential Biomarkers in Ulcerative Colitis and Crohn's Diseases.

The most well-known forms of inflammatory bowel disease (IBD) that affect the entire gastrointestinal tract are ulcerative colitis (UC) and Crohn's disease (CD). The serum profile of inflammatory biomarkers and noncoding RNA and their role in the propagation of the inflammatory process remains controversial. Thus, this study was designed to examine the relationship between hematological profile, C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), interferon-gamma (INF-γ), and the expression of LINC00641 and miR-378a in individuals with IBDs. In addition, we elucidated the correlation between the expression of LINC00641 and miR-378a and the biochemical variables analyzed. This retrospective study analyzed 94 unrelated participants. Group I included healthy controls, Group II consisted of participants diagnosed with UC, and Group III consisted of participants diagnosed with CD. Patients with IBDs experienced significant elevations in CRP, total leukocyte count, platelets, erythrocyte sedimentation rate, TNF-α, and INF-γ. However, participants with IBD had lower hemoglobin and albumin levels than healthy control participants. Moreover, the expression levels of LINC00641 and miR-378a were elevated in participants with IBD, with a significant difference between participants with IBD and healthy controls. The most striking observation was a clear association between serum LINC00641 and miR-378a levels and the biochemical variables assessed. This study demonstrated a positive correlation between the expression of LINC00641/miR-378a and TNF-α in patients with UC and CD patients. This study suggests that LINC00641 and miR-378a are prospective biomarkers and noninvasive screening tools for IBDs, which may help predict the progression of complications.
