Colorectal cancer (CRC) progression is profoundly shaped by the tumor microenvironment. Among stromal components, cancer-associated fibroblasts (CAFs) release small extracellular vesicles (exosomes) that deliver miRNAs, lncRNAs, circRNAs, proteins, and metabolites to malignant and immune cells. In CRC, CAF-derived exosomes (CAF-Exo) drive epithelial–mesenchymal transition, sustain stemness, stimulate angiogenesis, suppress antitumor immunity, and promote resistance to fluoropyrimidines and oxaliplatin. Representative mechanisms include exosomal miR-92a-3p activation of Wnt/β-catenin signaling, the lncRNA WEE2-AS1–mediated suppression of Hippo restraint with YAP activation, and circRNA cargos that reprogram autophagy or endothelial dynamics. Circulating CAF-Exo signatures are emerging as minimally invasive biomarkers for diagnosis, prognosis, and therapy stratification. However, translation remains limited by CAF heterogeneity, cargo variability, and incomplete in vivo characterization of vesicle dynamics. Therapeutic opportunities include blockade of exosome biogenesis or uptake, pharmacologic reprogramming of CAFs, and engineering vesicles to deliver targeted inhibitors or RNA-based therapeutics. This review synthesizes current mechanistic insights, evaluates biomarker potential, and outlines clinical priorities for targeting CAF-exosomal pathways in CRC.

Immune checkpoint inhibitors (ICIs) can elicit durable remissions, yet most solid tumors show primary non-response or acquired resistance because the tumor microenvironment (TME) limits T-cell priming, trafficking and effector fitness. Cytokines orchestrate these barriers by shaping spatial immune architecture, regulating suppressive myeloid programmes and inducing inhibitory ligands such as PD-L1. In this Review, we synthesize mechanistic and clinical evidence and propose a push–pull framework for cytokine modulation during checkpoint blockade: locally amplifying Th1/CTL-supporting signals (IL-2/IL-12/IL-15 and type I/II interferons) while selectively attenuating dominant suppressive circuits (TGF-β, IL-6/STAT3, IL-8–CXCR1/2, IL-10 and TNF-driven exhaustion). We critically contrast successful and failed cytokine–ICI combinations, highlighting how systemic exposure, network redundancy and counter-regulatory feedback have constrained several engineered agonists and explain why certain blockade strategies can improve efficacy while reducing immune-related toxicity. We discuss next-generation solutions—tumor-activated pro-cytokines, intratumoral gene delivery and immunocytokines—that concentrate activity within resistant niches and widen the therapeutic window. Finally, we outline actionable biomarkers, including transcriptomic signatures, plasma cytokine kinetics, myeloid/neutrophil metrics and spatial TME profiling, to stratify patients and guide dosing, sequencing and adaptive add-on strategies. Rational, biomarker-guided cytokine modulation offers a path to convert immune-excluded tumors into durable ICI responders.

Photodynamic therapy (PDT) has been extensively applied in the management of superficial cutaneous squamous cell carcinoma (cSCC). However, the efficacy of PDT was limited by issues including poor tissue penetration and hypoxia. In recent years, to enhance the effectiveness of PDT in cSCC, various combination strategies have been derived. Here, we revisit the basic mechanism of PDT and summarize clinical and basic researches of PDT-based combination strategies in treating cSCC, including topical agents, systemic therapies, and physical interventions. Evidences indicate that most of these combination approaches significantly enhanced the efficacy of PDT and leveraged three primary synergistic mechanisms: enhanced photosensitizer accumulation and delivery, potentiated tumor cell death, and augmented anti-tumor immunity. Future research should focus on optimizing light dosimetry, validating combination protocols in large clinical trials, and developing more tumor-targeted photosensitizers to improve PDT's clinical outcomes.

Non-small cell lung cancer (NSCLC) remains the leading cause of cancer-related death, driven by late diagnosis and therapeutic resistance. microRNAs (miRs) regulate post-transcriptional networks across cancer hallmarks and are unusually stable in biofluids, positioning them as powerful, minimally invasive biomarkers and therapeutic targets. This review summarizes current knowledge on miR biogenesis, regulation, and function in NSCLC; critically evaluates circulating and compartment-specific biomarkers (plasma/serum, sputum, and peripheral blood mononuclear cells (PBMCs); and appraises translational advances in oncomiR inhibition and tumor-suppressor restoration using modern delivery systems. We also analyze methodological progress, highlight persistent pre-analytical and normalization challenges, and outline practical routes toward regulatory-grade standardization. Convergent evidence indicates that circulating and exosomal miR panels can improve early detection and malignant-nodule triage, particularly when integrated with imaging and proteomic markers, and provide independent prognostic and treatment-monitoring value, often anticipating radiographic response or resistance. Despite strong pre-clinical efficacy, the clinical translation of miR mimics and inhibitors has been limited by delivery barriers and immunotoxicity, constraining progress into late-phase development. Unstandardized workflows and incomplete attribution of tumor-derived signals remain key barriers to clinical adoption. Overall, miRs hold strong potential to advance precision oncology in NSCLC through real-time disease monitoring and pathway-level targeting. Progress will likely depend on multimodal integration with circulating tumor DNA (ctDNA), proteomics, and imaging, alongside optimized delivery strategies, improved immunosafety, and rigorous multicenter validation to enable translation into routine care.

Breast cancer (BC) immunotherapy has transformed treatment paradigms, yet response rates remain limited by the complex interplay between cytokine networks and immune checkpoints. This review synthesizes emerging evidence on how cytokines dynamically regulate immune checkpoint expression and function within the breast tumor microenvironment. We examine pro-tumorigenic cytokine circuits alongside immunostimulatory pathways. A key focus is the subtype-specific nature of these interactions, with triple-negative breast cancers (TNBC) exhibiting distinct cytokine-checkpoint crosstalk compared to hormone receptor-positive subtypes. The review highlights innovative therapeutic strategies, including cytokine-targeting agents in clinical trials and engineered approaches like spatial-targeted nanocarriers. We further discuss how cutting-edge technologies from single-cell RNA sequencing to spatial proteomics are revealing novel biomarker opportunities. By decoding these intricate immune dialogues, this review provides a framework for developing precision immunotherapy combinations tailored to BC immunological heterogeneity.

Glioblastoma (GBM) is the most malignant form of primary brain tumor in adults, described by profound molecular heterogeneity, rapid progression, and limited therapeutic response. Despite advances in chemotherapy (TMZ), radiotherapy, and surgery, patient outcomes remain poor, with a median survival of 12–15 months. Traditional single-omics studies have identified critical biomarkers such as IDH mutations, MGMT promoter methylation, and EGFR alterations; however, these provide only partial insight into the disease's complexity. Recent integrative multi-omics approaches encompassing genomics, transcriptomics, epigenomics, proteomics, metabolomics, and non-coding RNAs have transformed the landscape of biomarker discovery in GBM. Genomic profiling has revealed recurrent mutations and subtype-specific aberrations, while transcriptomic analyses refine molecular classification and uncover alternative splicing and fusion events. Epigenomic markers, particularly MGMT methylation and G-CIMP status, are now central to prognosis and therapy stratification. Proteomic and metabolomic studies highlight dysregulated pathways, metabolic vulnerabilities, and non-invasive biomarkers in cerebrospinal fluid and plasma. Integrating multi-omics data not only improves diagnostic and prognostic accuracy but also unveils therapeutic targets, offering opportunities for precision oncology. Furthermore, liquid biopsy and single-cell/spatial omics enhance real-time monitoring of disease progression and treatment response, addressing challenges posed by intratumoral heterogeneity. This review synthesizes recent advances in GBM biomarker research across multiple omics layers, emphasizing their complementary roles in unravelling tumor biology, guiding personalized treatment, and shaping future therapeutic strategies.

As the most abundant innate immune cells in bone marrow and peripheral blood, neutrophils were once considered functionally homogeneous and exerted inflammatory and anti-infection functions. However, emerging evidence reshapes the perception of neutrophils from passive effectors to dynamic regulators with high plasticity and heterogeneity, especially within the tumor microenvironment (TME). This review summarizes recent advances, particularly driven by single-cell technologies, demonstrating that tumor-associated neutrophils (TANs) represent a continuum of distinct functional states originating from heterogeneous developmental pathways in bone marrow, circulation and spleen. We classified TANs into diverse subsets based on unique molecular signatures and functions, including pro-tumor, inflammatory, interferon-stimulated genes (ISGs)high, and antigen-presenting subsets, and highlighted that TANs profoundly impacting tumor progression through distinct molecular mechanisms. Importantly, we delineate how TANs functionally interact with T cells, NK cells, macrophages and other immune cells, revealing the pivotal role of TANs in reconfiguring immune response networks to modulate tumor progression. Lastly, we discuss emerging therapeutic strategies targeting TAN recruitment, reprogramming, or specific pro-tumor subsets to overcome therapy resistance, aiming to provide insights for future research directions on neutrophils and the development of neutrophil-targeted cancer therapeutic strategies.

The histone acetyltransferase complex HBO1 (KAT7) is an oncogenic regulator across multiple cancers, promoting cell proliferation and migration. Though clinically important, no targeted therapies address HBO1 dysregulation. HBO1 forms complexes with MEAF6, JADE(1/2/3), ING(ING4/5), and BRPF1/2/3 to acetylate histones H3 and H4, especially at H3K14, promoting transcriptional activation and genomic stability. It colocalizes with active transcriptional sites and participates in gene regulation, DNA repair and replication. Most HBO1-associated cancer mutations are missense, though their effects remain unclear. Silencing HBO1 restores normal proliferation and gene expression, underscoring its oncogenic role. HBO1 activity supports cancer pathways, including apoptosis resistance, DNA damage response, and cell cycle regulation. The HBO1 inhibitor WM-3835 disrupts H3K14 acetylation, reducing tumor growth in several cancers. This review provides insights into the function of HBO1 in cancer, especially in histone acetylation, ubiquitination, stem cell maintenance, and pro- and anti-oncogenic signaling. Understanding the roles of HBO1 may guide new epigenetic therapies for HBO1-driven malignancies.

F-box only protein 31 (FBXO31), a substrate adapter of SKP1-Cullin1-F-box (SCF) E3 ubiquitin ligase, was first identified as a candidate tumor suppressor in breast cancer due to its role in inducing senescence. Over the past two decades, FBXO31 has emerged as a crucial regulator in several human cancers, where it promotes the proteasomal degradation of various oncoproteins. FBXO31 plays a crucial role in regulating the cell cycle to maintain genomic integrity and inhibits processes such as epithelial-to-mesenchymal transition (EMT), invasion, and metastasis. This review examines the molecular mechanisms underlying the potent tumor-suppressive functions of FBXO31 in diverse human cancers. We also discuss the underlying causes of FBXO31 deregulation in cancer, providing insights into the intricate regulatory networks governing its expression. Additionally, we also examine the unexpected oncogenic functions of FBXO31 in certain cellular contexts. Finally, we highlight the clinical potential of FBXO31 in human malignancies, discussing its implications as both a biomarker and a therapeutic target. In conclusion, understanding the nuanced biology of FBXO31 is crucial for unravelling its role in tumorigenesis and advancing future therapeutic strategies.
F-box only protein 31 (FBXO31)是SKP1-Cullin1-F-box (SCF) E3泛素连接酶的底物适配器,由于其在诱导衰老中的作用,首次被发现是乳腺癌的候选肿瘤抑制因子。在过去的二十年中,FBXO31已经成为几种人类癌症的关键调节因子,它促进各种癌蛋白的蛋白酶体降解。FBXO31在调节细胞周期以维持基因组完整性和抑制上皮-间质转化(EMT)、侵袭和转移等过程中起着至关重要的作用。本文综述了FBXO31在多种人类癌症中有效肿瘤抑制功能的分子机制。我们还讨论了FBXO31在癌症中解除调控的潜在原因,提供了对控制其表达的复杂调控网络的见解。此外,我们还研究了FBXO31在某些细胞环境下意想不到的致癌功能。最后,我们强调了FBXO31在人类恶性肿瘤中的临床潜力,讨论了它作为生物标志物和治疗靶点的意义。总之,了解FBXO31的微妙生物学对于揭示其在肿瘤发生中的作用和推进未来的治疗策略至关重要。

Prostate cancer (PCa) is the second most common cancer among men worldwide and poses a significant threat to male health. A key feature of tumor progression is metabolic reprogramming, which involves the abnormal activation of glycolysis. This metabolic process supports PCa proliferation, metastasis, and drug resistance through rapid energy production, the provision of biosynthetic precursors, and the remodeling of the tumor microenvironment (TME). Key enzymes such as hexokinase 2 (HK2), phosphofructokinase (PFK), pyruvate kinase M2 (PKM2), glucose transporters (GLUTs), and lactate dehydrogenase A (LDHA) play pivotal roles in regulating aerobic glycolysis in PCa cells. Glycolytic enzymes are modulated by a variety of mechanisms, including the PI3K/AKT and AMPK signaling pathways, hypoxia-inducible factor 1α (HIF-1α), c-Myc, and non-coding RNAs. Current therapeutic strategies targeting glycolysis include natural products and small-molecule inhibitors. Targeting glycolysis presents novel opportunities to address existing limitations in PCa management. This review discusses the advances, challenges, and future research directions in glycolysis-focused PCa studies, providing a theoretical foundation for the development of precise metabolic interventions.
