Relative gene expression (RQ) of a KRAS, b PIK3CA, c AKT1, d CDKN2A in people with giardiasis by Real-time PCR method. Standard: Non-infected group. A2, A4, A8: Sample number of people with giardiasis. a The expression of gene KRAS was observed to decrease in samples A2 and A8 and increase in sample A4. b The expression of gene PIK3CA was decreased in samples A4 and A8, and there was no expression in sample A2. c The expression of gene AKT1 was increased in samples A4 and A8, and it was absent in sample A2. d The expression of gene CDKN2A in samples A2 and A4 had increased expression, and in sample A8, gene expression was almost equal to the standard sample
