• Physical exercise can exert antitumorigenic effects; however, the molecular mechanisms are still poorly understood. • Single-cell analysis may help to characterize the molecular mechanisms underlying the effects of exercise on anticancer immune function as well as on the complex tumor microenvironment. • Recent research using single-cell analysis provides preliminary insights into the molecular mechanisms behind an improved antitumor immunity in response to exercise. Particularly, there is evidence for a “reprogramming” of several immune effectors towards a higher antitumoral toxicity.

Background: Most RNA-seq datasets harbor genes with extreme expression levels in some samples. Such extreme outliers are usually treated as technical errors and are removed from the data before further statistical analysis. Here we focus on the patterns of such outlier gene expression to investigate whether they provide insights into the underlying biology.

Lung adenocarcinoma (LUAD) associated with usual interstitial pneumonia (UIP) harbours distinct features compared to lung adenocarcinoma without UIP. Therefore, we aimed to characterise the tumour microenvironment of LUAD with UIP by focusing on cancer-associated fibroblasts (CAFs) and stromal composition. Immunohistochemistry was performed on 32 LUAD samples (16 each with and without UIP) to evaluate CAF marker expression and lymphocyte infiltration.

Structural biology is fundamental to understanding the molecular basis of biological processes. While machine learning-based protein structure prediction has advanced considerably, experimentally determined structures remain indispensable for guiding structure-function analyses and for improving predictive modeling. However, experimental studies of protein complexes continue to pose challenges, particularly due to the necessity of high protein concentrations and purity for downstream analyses such as cryogenic electron microscopy.

Breast cancer is a highly heterogeneous disease with diverse outcomes, and intra-tumoral heterogeneity plays a significant role in both diagnosis and treatment. Despite its importance, the spatial distribution of intra-tumoral heterogeneity is not fully elucidated. Spatial transcriptomics has emerged as a promising tool to study the molecular mechanisms behind many diseases.

Background And Purpose: Colonoscopy is an essential diagnostic and therapeutic tool for lower gastrointestinal bleeding (LGIB), with colonoscopic hemostasis needed in a subset of patients. We aim to identify risk factors associated with colonoscopic hemostasis requirement in acute LGIB patients.
Methods: This retrospective study examined consecutive patients who underwent colonoscopy for acute LGIB at a single tertiary hospital between November 2020 and May 2023.
