Does miRNA-155 Promote Cyclooxygenase-2 Expression in Cancer?

نویسنده

  • Brian S Comer
چکیده

Preclinical Research MicroRNA (miR)-155 and cyclooxygenase (COX)-2 are both elevated in numerous cancers including colorectal cancer. MiR-155 enhances COX-2 expression and is an established regulator of epithelial-mesenchymal transition and inflammation. Inhibition of miR-155 or COX-2 exhibit similar negative effects on tumorigenicity. Thus, it is hypothesized that miR-155 may be a promising target for antagonizing COX-2 expression in colorectal and other cancers.

The role of microRNA in acute/chronic, myeloid/lymphocytic leukemia

MicroRNAs are small, non-coding sequences that regulate gene expression by inducing degradation or translational inhibition of target mRNAs. These molecules control many intracellular physiological and pathological processes.Abnormal expression of these moleculs has been described in different cancers including hematopoietic cancers. According to the type of cancer and the stage, miRNA’s expres...

MicroRNA-155 in oral squamous cell carcinoma: Overexpression, localization, and prognostic potential.

BACKGROUND Oral squamous cell carcinoma (OSCC) is a common malignancy with poor prognosis. MicroRNAs (miRNAs) play an important role in cancer, but their role in OSCC is not clarified. METHODS We performed miRNA microarray, quantitative reverse transcription polymerase chain reaction (qRT-PCR), and fluorescence in situ hybridization (FISH) to examine miRNA expression in OSCC and paired adjace...

Analyzing the Expression Level and Associated Clinical Characteristics of miRNA-138 in Esophageal Squamous Cell Carcinoma in Iranian Patients

Background: Esophageal Squamous Cell Carcinoma (ESCC) is the seventh most common and lethal malignancy worldwide with a high incidence in Iran. Esophageal cancer has a poor prognosis and low 5-years survival rate. Despite several studies on esophageal cancer, its underlying mechanism remains unclear. Therefore, it is significant to analyze the molecular factors involved in disease for introduci...
