The expression levels of (A) mir-16, (B) mir-21, (C) mir-29a, (D) mir-223, and (E) mir-874 in the Caco-2 cell line co-incubated with B3STA, isolated from symptomatic carrier, 24 h after exposure. Accordingly, the B3STA significantly downregulated mir-29a, and upregulated mir-223 and mir-874. In addition, LPS significantly downregulated mir-16, while upregulated mir-29a, mir-223, and mir-874. Comparison between LPS and B3STA was statistically significant only in mir-16, mir-29a, and mir-874. * P value < 0.05; ** P value < 0.01; *** P value < 0.001; **** P value < 0.0001. Comparisons were carried out using the Student’s t-test. Mir: microRNA; Caco-2: human colon carcinoma; B3STA: Blastocystis sp., ST3 soluble total antigen; LPS: lipopolysaccharide; NS: not significant
