Pancreatic cancer (PC) is an extremely deadly type of cancer, and the 5-year survival rate remains less than 10%. The tumour microenvironment (TME) affects the occurrence, progression and treatment outcomes of PC. MicroRNAs (miRNAs) are essential to regulate PC TME. This review delves into the different roles of miRNAs in the PC TME, including exosome communication, angiogenesis, interactions with cancer-associated fibroblasts, the immunological and neuronal microenvironments and metabolic reprogramming. However, research on the complex regulatory networks and synergistic effects of miRNAs in the TME is still insufficient, and their clinical translation and application face challenges. This review summarised the activities of miRNAs in the PC TME, guiding future research and therapeutic strategies involving miRNAs in PC. Future studies should integrate advanced technologies to decode the spatiotemporal dynamics of miRNA regulation within the TME and develop optimised nanodelivery systems for stable and targeted miRNA delivery, advancing clinical applications in PC treatment.

Tumour progression depends on the bidirectional interactions between cancer and stroma in the heterogeneous tumour microenvironment (TME) partially through extracellular vesicles (EVs). However, the secretary mechanism and biological effect of cancer cell derived EVs on tumour survival under starvation is poorly defined. Here, we identify cancer cells selectively secrete miR-33a with the assistance of aconitase 1 (ACO1), an iron-responsive RNA binding protein, under glucose starvation and lower iron level, which affiliates the binding capability of miR-33a and ACO1.

Ferroptosis, a form of regulated cell death characterized by the accumulation of lipid peroxides, has emerged as a crucial player in cancer biology, particularly in breast cancer. This review article explores the intricate regulation of ferroptosis by non-coding RNAs (ncRNAs) within the breast cancer tumor microenvironment (TME). We delve into the mechanisms through which various classes of ncRNAs, including microRNAs, long non-coding RNAs, and circular RNAs, modulate the ferroptotic response in breast cancer cells.

Glioblastoma multiforme (GBM) is the most aggressive and lethal primary brain tumor in adults, characterized by high intratumoral heterogeneity, therapy resistance, and poor prognosis. Nuclear factor-κB (NF-κB) signaling plays a pivotal role in GBM pathogenesis by promoting proliferation, invasion, inflammation, immune evasion, and treatment resistance. This review provides a comprehensive overview of canonical and non-canonical NF-κB signaling pathways and their molecular mechanisms in GBM, with a focus on their regulation in glioma stem-like cells (GSCs), interactions with key oncogenic factors (including STAT3, FOSL1, and TRPM7), and roles in maintaining tumor stemness, metabolic adaptation, and angiogenesis.

Background: Cervical cancer remains a global public health challenge, particularly in regions with limited access to screening and vaccination. While high-risk HPV infection is the primary cause, the genetic and molecular mechanisms driving cervical cancer progression are not fully understood.
Objective: This study integrates Mendelian randomization (MR) and single-cell RNA sequencing (scRNA-seq) to identify causal eQTL-related genes and explore their roles in tumorigenesis.

Background: Communication between cancer cells and tumor microenvironment (TME) plays a complicated role in cancer malignancy. Circular RNAs (circRNAs), known for their stability and conservation, contribute to TME remodeling in various cancers. This study aims to investigate the role of N6-methyladenosine (m6A)-modified circZNF548 in the proliferation and migration of non-small cell lung cancer (NSCLC) within the TME.
