Introduction: Esophageal squamous cell carcinoma (ESCC), is the most common type of
esophageal cancer worldwide, mainly occurring in the Asian esophageal cancer.
Phosphatidlinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin
(mTOR) signaling pathway is one of the most important cellular signaling pathways, which
plays a crucial role in the regulation of cell growth, differentiation, migration, metabolism and
proliferation. MicroRNAs, are small noncoding RNAs which regulate gene expression
primarily at the posttranscriptional level and their expression profile improve classification
diagnosis and prognostic information of malignancies including ESCC cancer as oncogene or
tumor suppressor. Here in, this study investigates the communication between mir-199a-5p,
3120d, 215, 194, 664a and ESCC cancer in cellular pathways.
Methods: By using mirbase,
miRNA properties were obtained. The mirtarbase and MIRWALK2.0 target genes were
identified. Through NCBI, the expression of target genes in the normal and ESCC tissue was
obtained. Using DAVID, signal paths were obtained and the pathways associated with ESCC
were interpreted. The gene network was obtained through GENE MANIA.
Results: The result
demonstrated that mir199a-5p, 3120d, 215, 194 and 664a inhibit ERK by blocking Ras, SOS
which active Raf, MEK through phosphorylation. So ERK by blocking ELK, MYC effect on
adhesion increasing through preventing cell migration and suppress cancer. Mentioned
microRNA by inhibiting EGFR, Ras, SOS, ERK inhibit proliferation of cancer cell and tumor
spread. MicroRNAs by inhibiting Ras, PI3K take their stimulation impact of PIP3 and block
Act, IKK, NFkB and prevent cell migration and metastasis.
Conclusion: Mir199a-5p, 3120d,
215, 194 and 664a effect on metastasis, proliferation and adhesion of cancer cell. Mentioned
microRNAs by effecting on Act, Ras, SOS, EGFR, MAPK1, PI3K in ERB, Non-small cell
ESCC cancer, RAS, PI3-ACT pathways, inhibit proliferation and metastasis by effecting on
adhesion increasing and prevent cell migration. Therefore MicroRNAs act as tumor suppressor
and destroy cancer by preventing the development of cancer cell and spread of
tumor.
