Cancer is a complex genetic disorder characterized by abnormalities in both coding and regulatory non-coding RNAs. microRNAs (miRNAs) are key RNAs that modulate cancer development, functioning as tumor suppressors oncogenes. miRNAs play critical roles progression, influencing processes such initiation, promotion, metastasis. They exert their effects targeting suppressor genes, thereby facilitating while also inhibiting oncogenes to prevent further disease advancement. The miR-10 family, particularly miR-10a-5p miR-10b-5p (miR-10a/b-5p), notably involved progression. Intriguingly, functions can differ across different cancers, sometimes promoting at other times suppressing growth depending on the type target genes. This review explores dual of miR-10a/b-5p tumor-suppressive (TSmiRs) or oncogenic (oncomiRs) various cancers examining molecular cellular mechanisms impact microenvironment. Furthermore, we discuss potential therapeutic targets, emphasizing miRNA-based strategies for treatment. insights discussed this aim advance our understanding miR-10a/b-5p’s biology application developing innovative therapies.

Therefore, understanding how this communicates with crucial for the development new anti-cancer therapies. MicroRNAs (miRNAs) are small non-coding RNAs that inhibit gene expression. They secreted into extracellular medium in vesicles called exosomes, which allow communication via transfer cargo. Consequently, we hypothesized circulating endothelial miRNAs could be transferred to modify phenotype. Using exogenous miRNA, demonstrated can miRNA exosomes. profiling, identified exhibited downregulated levels exosomes released from cultured under tumoral conditions. modulation miR-503 breast cancer altered proliferative invasive capacities. We then two targets CCND2 CCND3. Moreover, measured increased plasmatic patients after neoadjuvant chemotherapy, partly due secretion by cells.

Immune Modulatory microRNAs Involved in Tumor Attack and Tumor Immune Escape

JNCI Journal of the National Cancer Institute, Год журнала: 2017, Номер 109(10)

Опубликована: Март 16, 2017

Current therapies against cancer utilize the patient's immune system for tumor eradication. However, cells can evade surveillance of CD8+ T and/or natural killer (NK) by various strategies. These include aberrant expression human leukocyte antigen (HLA) class I antigens, co-inhibitory or costimulatory molecules, and components interferon (IFN) signal transduction pathway. In addition, alterations microenvironment could interfere with efficient antitumor responses downregulating inhibiting frequency functional activity effector professional antigen-presenting cells. Recently, microRNAs (miRNAs) have been identified as major players in post-transcriptional regulation gene expression, thereby controlling many physiological also pathophysiological processes including neoplastic transformation. Indeed, cellular miRNA pattern is frequently altered tumors distinct origin, demonstrating suppressive oncogenic potential miRNAs. Furthermore, there increasing evidence that miRNAs influence affecting modulatory molecules Apart from their important role escape tumor-host interaction, often exert properties, thus representing promising targets future combined immunotherapy approaches. This review focuses on characterization involved use diagnostic prognostic biomarkers therapeutic targets.

MicroRNA Control of TGF-β Signaling

International Journal of Molecular Sciences, Год журнала: 2018, Номер 19(7), С. 1901 - 1901

Transcriptional and post-transcriptional regulation shapes the transcriptome proteome changes induced by various cellular signaling cascades. MicroRNAs (miRNAs) are small regulatory RNAs that approximately 22 nucleotides long, which direct of diverse target genes control cell states. Transforming growth factor (TGF)-β family is a multifunctional cytokine family, plays many roles in development pathogenesis diseases, including fibrotic disease, cardiovascular disease cancer. Previous studies have shown TGF-β pathway includes miRNA as an important component its downstream Multiple epithelial–mesenchymal transition (EMT)-related miRNAs highlighted constitute intrinsic bistable molecular switches states forming double negative feedback loops with EMT-inducing transcription factors. This may be for understanding reversibility EMT at single-cell level, presence distinct intra- inter-tumor heterogeneity cancer phenotypes. In present review, I summarize connection between pathway, placing particular emphasis on expression signaling, modulation miRNAs, miRNA-mediated endothelial–mesenchymal well crosstalk pathways tumor microenvironment.

Hepatic stellate cells (HSCs) are a significant component of the hepatocellular carcinoma (HCC) tumor microenvironment (TME). Activated HSCs transform into myofibroblast-like to promote fibrosis in response liver injury or chronic inflammation, leading cirrhosis and HCC. The hepatic TME is comprised cellular components, including activated HSCs, tumor-associated macrophages, endothelial cells, immune non-cellular components such as growth factors, proteolytic enzymes their inhibitors, other extracellular matrix (ECM) proteins. Interactions between HCC have become topics under active investigation. These interactions within potential drive carcinogenesis create challenges generating effective therapies. Current studies reveal mechanisms through which hepatocarcinogenesis utilizing matricellular proteins paracrine crosstalk TME. Since primary secretors ECM during they help fibrogenesis, infiltrate stroma, contribute development. In this review, we examine several recent revealing roles clinical implications development
