The interaction of tumor cells and their microenvironment is thought to be a key factor in tumor development. We present spatial RNA profiles obtained from 30 lung adenocarcinoma patients at the non-invasive and later invasive stages. We use spatial transcriptome sequencing data in conjunction with in situ RNA profiling to conduct higher resolution analyses. The detailed examination of each case, as well as the subsequent computational analyses based on the observed diverse profiles, reveals that significant changes in the phenotypic appearances of tumor cells are frequently associated with changes in immune cell features. The phenomenon coincides with the induction of a series of cellular expression programs that enable tumor cells to transform and break through the immune cell barrier, allowing them to progress further. The study shows how lung tumors develop through interaction in their microenvironments.

Although cold atmospheric plasma is a promising therapeutic technique for tumor immunotherapy via reactive oxygen and nitrogen species (RONS), the challenges associated with the generation and delivery of these RONS hamper clinical adoption. Herein, a dual-mode hybrid discharge plasma-activated sodium alginate hydrosols (PAH) is proposed to enhance the antitumor immune response. Gaseous highly reactive RONS are generated by dual-mode hybrid plasma produced by mixed O and NO modes, which are converted into aqueous RONS in PAH via gas-liquid reactions between plasma and hydrosols.

Compared to sun-exposed melanomas, acral melanomas are genetically diverse and occur in areas with low sun exposure and high mechanical loads. During metastatic growth, melanomas invade from the epidermis to the dermis layers through dense tumor stroma and are exposed to fibrillar collagen architectures and mechanical stresses. However, the role of these signals during acral melanoma pathogenesis is not well understood.

Background: Inflammation impacts the prognosis of numerous types of tumors. Inflammatory indicators such as the neutrophil-to-lymphocyte ratio, lymphocyte-to-monocyte ratio, and neutrophil-to-eosinophil ratio (NER) have emerged as potential prognostic markers and are closely correlated with the outcomes of cancer patients. However, the connection between NER and cancer prognosis remains incompletely understood.

Purpose: We reviewed recent advancements in the characterization of intraductal oncocytic papillary neoplasm (IOPN) of the pancreas, with a specific focus on developments in immunohistochemical markers, molecular pathology, and pathogenic mechanisms over the past ten years (2015-2024). Through comprehensive analysis of current literature, we aimed to elucidate the evolving understanding of IOPN's biological behavior and diagnostic features, while identifying potential areas for future research in this distinctive pancreatic neoplasm.
Methods: English-language articles on IOPN were searched from Pubmed from the first report of IOPN of the pancreas in 2015 to 2024.

It has become evident from decades of clinical trials that multimodal therapeutic approaches with focus on cell intrinsic and microenvironmental cues are needed to improve understanding and treat the rare, inoperable, and ultimately fatal diffuse intrinsic pontine glioma (DIPG), now categorized as a diffuse midline glioma. In this study we report the development and characterization of an in vitro system utilizing 3D Tumor Tissue Analogs (TTA), designed to replicate the intricate DIPG microenvironment. The innate ability of fluorescently labeled human brain endothelial cells, microglia, and patient-derived DIPG cell lines to self-assemble has been exploited to generate multicellular 3D TTAs that mimic tissue-like microstructures, enabling an in- depth exploration of the spatio-temporal dynamics between neoplastic and stromal cells.
