MicroRNA MIR21 and T Cells in Colorectal Cancer.
The complex interactions between colorectal neoplasia and immune cells in the tumor microenvironment remain to be elucidated. Experimental evidence suggests that microRNA MIR21 (miR-21) suppresses antitumor T-cell-mediated immunity. Thus, we hypothesized that tumor MIR21 expression might be inversely associated with T-cell density in colorectal carcinoma tissue. Using 538 rectal and colon cance...
متن کاملMicroRNA MIR21 (miR-21) and PTGS2 Expression in Colorectal Cancer and Patient Survival.
PURPOSE Prostaglandin-endoperoxide synthase 2 (PTGS2, cyclooxygenase-2; a target of aspirin) produces inflammatory mediator prostaglandin E2 (PGE2), and contributes to colorectal neoplasia development. PTGS2-driven inflammatory responses can induce tumor expression of microRNA MIR21 (miR-21) that can increase local PGE2 level by downregulating PGE2-metabolizing enzymes. We hypothesized that the...
متن کاملinterpersonal function of language in subtitling
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولSpecificity and functionality of microRNA inhibitors
BACKGROUND Micro(mi)RNAs regulate gene expression through translational attenuation and messenger (m)RNA degradation, and are associated with differentiation, homeostasis and disease. Natural miRNA target recognition is determined primarily by perfect complementarity in a seed region (nucleotide positions 2 to 7) with additional interactions contributing in a sequence- and target-specific manne...
متن کاملMicroRNA control of ovarian function.
Post-transcriptional gene regulation, a regulatory mechanism classically involved in female and male germ cell function has recently been implicated in control of somatic cells of the ovary and testis. Recent advancements in this field may be attributed primarily to the discovery and study of microRNAs (miRNA), small RNA transcripts that can influence mRNA expression via post-transcriptional ge...
