Abstract Recent developments in immuno-oncology demonstrate that not only cancer cells, but also the tumor microenvironment can guide precision medicine. A comprehensive and in-depth characterization of is challenging since its cell populations are diverse be important even if scarce. To identify clinically relevant microenvironmental features, we applied single-cell RNA sequencing to ten human lung adenocarcinomas normal control tissues. Our analyses revealed heterogeneous carcinoma transcriptomes reflecting histological grade oncogenic pathway activities, two distinct patterns. The immune-activated CP²E was composed cancer-associated myofibroblasts, proinflammatory monocyte-derived macrophages, plasmacytoid dendritic cells exhausted CD8+ T prognostically unfavorable. In contrast, inert N³MC characterized by normal-like non-inflammatory NK myeloid conventional associated with a favorable prognosis. Microenvironmental marker genes signatures identified profiles had progonostic value bulk profiles. summary, profiling adenocarcinoma provides additional prognostic information based on microenvironment, may help predict therapy response reveal possible target for future therapeutic approaches.

Among all the stromal cells that present in tumor microenvironment, cancer-associated fibroblasts (CAFs) are one of most abundant and critical components mesenchyme, which not only provide physical support for but also play a key role promoting retarding tumorigenesis context-dependent manner. CAFs have been involved modulation many immune system, recent studies revealed their roles evasion poor responses to cancer immunotherapy. In this review, we describe our current understanding tumorigenic significance, origin, heterogeneity CAFs, as well different subtypes distinct cell types.

Abstract Metastasis is the primary cause of cancer morbidity and mortality. The process involves a complex interplay between intrinsic tumor cell properties as well interactions cells multiple microenvironments. outcome development nearby or distant discontiguous secondary mass. To successfully disseminate, metastatic acquire in addition to those necessary become neoplastic. Heterogeneity mechanisms involved, routes dissemination, redundancy molecular pathways that can be utilized, ability piggyback on actions surrounding stromal makes defining hallmarks metastasis extraordinarily challenging. Nonetheless, this review identifies four distinguishing features are required: motility invasion, modulate site local microenvironments, plasticity, colonize tissues. By these first principles metastasis, we provide means for focusing efforts aspects will improve patient outcomes.

Intratumoral heterogeneity is a critical frontier in understanding how the tumor microenvironment (TME) propels malignant progression. Here, we deconvolute human pancreatic TME through large-scale integration of histology-guided regional multiOMICs with clinical data and patient-derived preclinical models. We discover "subTMEs," histologically definable tissue states anchored fibroblast plasticity, relationships to immunity, subtypes, differentiation, treatment response. "Reactive" subTMEs rich complex but functionally coordinated communities were immune hot inhabited by aggressive cell phenotypes. The matrix-rich "deserted" harbored fewer activated fibroblasts tumor-suppressive features yet markedly chemoprotective enriched upon chemotherapy. SubTMEs originated differentiation trajectories, transitory notable both single-cell transcriptomics situ. intratumoral co-occurrence produced patient-specific phenotypic computationally predictable tightly linked biology.

Abstract Extracellular vesicles (EVs) are nano-sized, membranous structures secreted into the extracellular space. They exhibit diverse sizes, contents, and surface markers ubiquitously released from cells under normal pathological conditions. Human serum is a rich source of these EVs, though their isolation proteins non-EV lipid particles poses challenges. These transport various cellular components such as proteins, mRNAs, miRNAs, DNA, lipids across distances, influencing numerous physiological events, including those within tumor microenvironment (TME). Their pivotal roles in communication make EVs promising candidates for therapeutic agents, drug delivery systems, disease biomarkers. Especially cancer diagnostics, EV detection can pave way early identification offers potential diagnostic Moreover, subtypes emerging targeted tools, highlighting clinical significance. The need non-invasive biomarkers to monitor biological processes purposes remains unfulfilled. Tapping unique composition could unlock advanced avenues future.

Hypoxia, a common feature of the tumor microenvironment in various types cancers, weakens cytotoxic T cell function and causes recruitment regulatory cells, thereby reducing tumoral immunogenicity. Studies have demonstrated that hypoxia hypoxia-inducible factors (HIFs) 1 2 alpha (HIF1A HIF2A) are involved immune escape. Under hypoxia, activation HIF1A induces series signaling events, including through programmed death receptor-1/programmed ligand-1. Moreover, triggers shedding complex class I chain-associated molecules nitric oxide impairment to disrupt surveillance by natural killer cells. The HIF-1-galactose-3-O-sulfotransferase 1-sulfatide axis enhances escape via increased cell-platelet binding. HIF2A upregulates stem factor expression recruit tumor-infiltrating mast cells increase levels cytokines interleukin-10 transforming growth factor-β, resulting an immunosuppressive microenvironment. Additionally, tumor-associated long noncoding RNAs suppresses function, enabling Overall, elucidating underlying mechanisms which HIFs promote evasion will allow for targeting HIF treatment.

Abstract Metastasis is initiated and sustained through therapy by cancer cells with stem-like immune-evasive properties, termed metastasis-initiating (MIC). Recent progress suggests that MICs result from the adoption of a normal regenerative progenitor phenotype malignant cells, intrinsic programs to survive stresses metastatic process, undergo epithelial–mesenchymal transitions, enter slow-cycling states for dormancy, evade immune surveillance, establish supportive interactions organ-specific niches, co-opt systemic factors growth recurrence after therapy. Mechanistic understanding molecular mediators MIC phenotypes host tissue ecosystems could yield therapeutics improve patient outcomes.
