Article Abstract

Platelet reactive protein 2 (PRP2) is closely related to the characteristics of tumor stem cells. Its role in cancer development and metastasis has received increasing attention, especially its interaction with the immune microenvironment. The study used cluster analysis to extract expression data of multiple cancer types from public databases, and combined with immune infiltration analysis, to evaluate the expression level of PRP2 and its correlation with different immune cell infiltration. Bioinformatics tools were used to analyze the correlation between PRP2 and tumor stem cell markers. The results show that PRP2 is significantly upregulated in a variety of cancers and is closely related to tumor stem cell characteristics. Immunoinfiltration analysis showed that the high expression of PRP2 was associated with a significant increase in immunosuppression-related cell infiltration. Through cluster analysis, we identified the expression pattern of PRP2 in different cancer types, indicating that it may be used as a biomarker for early diagnosis and prognosis assessment, and its expression is closely related to the immune microenvironment, indicating its important role in cancer biology and potential application value in the tumor immune microenvironment.

Background: The cluster of differentiation 47 (CD47)-signal regulatory protein alpha (SIRPα) axis is a key regulator of innate immune surveillance, facilitating the neoplastic evasion of macrophage-mediated phagocytosis. Although this pathway has been implicated in tumor immune escape in multiple malignancies, its clinical and prognostic significance in esophageal squamous cell carcinoma (ESCC) remain to be fully elucidated.

Methods: We retrospectively analyzed 100 patients who underwent esophagectomy for resectable ESCC.

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.

Background: Informal caregivers of home-dwelling people with dementia experience significant unmet needs. However, family physician teams as primary health care gatekeepers for aging populations in China remain an underused resource for structured caregiver support.

Objective: This hybrid effectiveness-implementation study aimed to evaluate a policy-aligned integration of the World Health Organization's iSupport web-based program with China's family physician contract services for informal dementia caregivers while systematically assessing implementation determinants using the Consolidated Framework for Implementation Research (CFIR).
