(. ) is widely used in traditional Chinese medicine due to its anti-tumor effects. . shifts liver cancer tumor microenvironment towards regression by hindering tumor-associated macrophages polarization. Huang have demonstrated in their study that . inhibits M2-tumour-associated macrophages (TAM) polarization by halting the Wnt/β-catenin pathway. The mechanism of action by which . exerts its anti-tumor effects is multifaceted and includes network pharmacology, transcriptomics and molecular docking. assays demonstrated that . -containing serum inhibited M2-TAMs polarization in human hepatocellular carcinomas cells. . was found to have 22 active components of which 11 were detected in the bloodstream. The anti-neoplastic activity of . lies in suppressing M2-TAM polarization by modulation of the Wnt/B-catenin pathway. and experiments have shown that . suppresses M2-TAM polarization and halts the Wnt signaling pathway. The inhibitory effect of . on M2-TAM was reversed by SKL2001, a Wnt agonist, which highlights . 's selectivity and specificity. . inhibits M2-TAM polarization by modulating the Wnt/ β-catenin pathway, thus impeding liver cancer growth. Owing to the "cross-talk" between transforming growth factor-β (TGF-β) signaling pathways, this paper highlights the potential significance of . in controlling the tumor microenvironment not only through hindering the polarization of M2-TAMs the Wnt signaling pathway, but also by downregulating TGF-β. Therefore, . serves as an igniter to fuel a cascade of signaling events that culminates in the regression of the tumor microenvironment by compromising oncogenesis and angiogenesis. TGF-β is also known for its pro-fibrotic properties. Therefore, . may play a pivotal role in treating liver fibrosis by downregulating TGF-β, thus hindering oncogenesis, angiogenesis and liver fibrosis. Hence, the "domino effect".

Tumorigenesis involves a multifaceted and heterogeneous interplay characterized by perturbations in individual immune surveillance. Tumor-infiltrating lymphocytes, as orchestrators of adaptive immune responses, constitute the principal component of tumor immunity. Over the past decade, the functions of tumor-specific T cells have been extensively elucidated, whereas current understanding and research regarding intratumoral B cells remain inadequate and underexplored.

Copper plays an important role in the regulation of PD-L1, suggesting that reducing copper levels within tumors may enhance anti-cancer immunotherapy. Tumor microenvironment responsive copper nanodeprivator (TMECN) was developed for enhancing immunotherapy of tumor via the cross-link of mercaptopolyglycol bipyridine and dimercaptosuccinic acid modifying FePt nanoalloy using the disulfide bond. Upon entering tumor cells, the disulfide bond in TMECN is cleaved by the overexpressed glutathione, exposing abundance of sulfhydryl groups.

Glioblastoma IDH wild type (GBM IDH wt) has a poor prognosis and a strongly associated with inflammatory processes. Inflammatory molecules generate positive feedback with tumor cells fueling tumor growth as well as recruitment of immune cells that promote aggressiveness. Although the role of many inflammatory molecules is well known, there are many macromolecules, such as the S100A proteins, whose role is only now beginning to be established.

Oral squamous cell carcinoma (OSCC) is a highly aggressive and malignant tumor of oral cavity with a poor prognosis and high mortality due to the limitations of existing therapies. The significant role of tumor microenvironment (TME) in the initiation, development, and progression of OSCC has been widely recognized. Various cells in TME, including tumor-associated macrophages (TAMs), cancer-associated fibroblasts (CAFs), T lymphocytes, tumor-associated neutrophils (TANs), myeloid-derived suppressor cells (MDSCs) and dendritic cells (DCs), form a complicated and important cellular network to modulate OSCC proliferation, invasion, migration, and angiogenesis by secreting RNAs, proteins, cytokines, and metabolites.

Autophagy is a common cellular degradation and recycling process that plays crucial roles in the development, progression, immune regulation, and prognosis of various cancers. However, a systematic assessment of the autophagy-related genes (ATGs) across cancer types is deficient. Here, a transcriptome-based pan-cancer analysis of autophagy with potential implications in prognosis and therapy response was performed.
