Despite its fundamental role, research on the TRAP/SSR complex in human diseases remains limited, focusing mainly on its involvement in cancer, diabetes, neurodegenerative and spinal disorders, and hepatitis B virus infection. This review summarizes recent advances in understanding TRAP/SSR function in disease pathogenesis, highlighting its pro-tumorigenic activity, regulation of insulin biosynthesis and secretion, and potential as a biomarker for early diagnosis of neurodegenerative and spine-related disorders. Furthermore, the TRAP/SSR complex facilitates the translocation and secretion of the hepatitis B e antigen, emphasizing its role in viral pathogenesis. However, substantial research gaps persist due to the novelty of this field, and the molecular mechanisms underlying TRAP/SSR-mediated disease regulation remain incompletely understood. Therefore, future investigations should aim to elucidate the mechanistic links between TRAP/SSR dysfunction and diverse pathological conditions, including metabolic, neurodegenerative, infectious, and malignant diseases. Defining disease-specific downstream effectors and interactions with ER stress pathways – particularly the unfolded protein response and ER-associated degradation – will be critical to clarifying its contribution to cellular homeostasis and disease progression. The development of targeted therapeutic strategies to modulate TRAP/SSR activity, supported by integrative multi-omics and structural biology approaches, may ultimately enable the translation of these insights into diagnostic and therapeutic applications.</div></div>","PeriodicalId":29686,"journal":{"name":"Human Gene","volume":"46 ","pages":"Article 201510"},"PeriodicalIF":0.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145519418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to identify molecular signature genes associated with GBM heterogeneity using scRNA-seq datasets from 10× Genomics. Two scRNA-seq datasets were processed through the Cell Ranger pipeline, followed by quality control, normalization, and scaling. After data integration using R, Principal Component Analysis was performed, and clusters were visualized using UMAP.
