Abstract Exosomes derived from cancer are regarded as significant mediators of cancer-host crosstalk. Hypoxia, on the other hand, is one essential characteristics solid tumors. This research set out to discover how circulating exosomes hypoxic esophageal squamous cell carcinoma (ESCC) contribute formation metastatic niches and distant metastasis. First, we noticed that human umbilical vein endothelial cells (HUVECs) had their tight connections disrupted expression proteins involved in angiogenesis boosted by ESCC exosomes. Hypoxia significantly induced Circ-ZNF609 ESCC, which was then internalized HUVECs, determined circular RNA screening. High HUVECs facilitated vascular permeability, thereby promoting pre-metastatic niche formation, enhancing metastasis vitro vivo. Exosomal activated growth factor A (VEGFA) mechanistically sponging miR-150-5p. also interacted with HuR inhibited binding ZO-1, Claudin-1, Occludin mRNAs, reducing translation. Collectively, our findings identified an function for exosomal cells, suggesting potential therapeutic value patients.

MicroRNAs (miRNAs) are mighty post-transcriptional regulators in cell physiology and pathophysiology. In this review, we focus on the role of miR-223-3p (henceforth miR-223) various cancer types. MiR-223 has established roles hematopoiesis, inflammation, most cancers, where it can act as either an oncogenic or oncosuppressive miRNA, depending specific molecular landscapes. also been linked to sensitivity resistance cells treatments a context-dependent way. Through detailed highlight that for some cancers (i.e., breast, non-small lung carcinoma, glioblastoma), miR-223 is consistently reported literature, while others colorectal, ovarian, pancreatic acute lymphocytic leukemia), prevails. prostate other hematological malignancies, although frequently described, there less consensus. Intriguingly, NLRP3 FBXW7 identified targets when miRNA acts oncosuppressor oncogene, respectively, different cancers.

Glioblastoma remains one of the most aggressive cancers brain, warranting new methods for early diagnosis and more efficient treatment options. Circular RNAs (circRNAs) are rather entities with increased stability compared to their linear counterparts that interact proteins act as microRNA sponges, among other functions. Herein, we provide a critical overview recently described glioblastoma-related circRNAs in literature, focusing on roles glioblastoma cancer cell proliferation, survival, migration, invasion metastasis, metabolic reprogramming, therapeutic resistance. The main regulating processes due regulatory essential oncogenic pathways, including MAPK, PI3K/AKT/mTOR, Wnt, which influenced by various circRNAs. present work pictures wide implication glioblastoma, thus highlighting potential future biomarkers targets/agents.

CircRNAs are a class of non-coding RNAs able to regulate gene expression at multiple levels. Their involvement in physiological processes, as well their altered regulation different human diseases, both tumoral and non-tumoral, is documented. However, little known about female reproduction. This study aims identify circRNAs potentially involved reproductive women’s health. Candidate expressed ovary sponging miRNAs, already be the ovary, were selected by computational approach. Using real time PCR, we verified identified circPUM1 most interesting candidate circRNA for further analyses. We assessed its linear counterpart all follicle compartments and, using experimental approach, direct indirect targets, miRNAs mRNAs, respectively, cumulus cells. found that mRNA host co-expressed proposed potential regulator PTEN, finding strong positive correlation between PTEN mRNA. These results suggest possible cells point out important role inside pathways related growth oocyte maturation.

This review examines the prevalence, molecular mechanisms, and clinical implications of RAS mutations in Central Nervous System (CNS) tumors, with a particular focus on glioblastoma. We summarize current understanding RAS-driven oncogenic pathways, their contribution to tumor progression, potential therapeutic strategies targeting its downstream effectors. Although direct are rare primary CNS alterations signaling, such as NF-1 loss aberrant receptor tyrosine kinase activation, contribute malignant progression. Furthermore, emerging evidence links brain metastases, highlighting significance oncology. also discuss recent trials investigating RAS-targeted therapies, including covalent inhibitors, MEK novel combination approaches.
