Cytoplasmic HuR Expression Enhances Chemoresistance in Pleural Mesothelioma Through Increased Expression of CALB2, Promotion of the E2F Pathway, and Suppression of the p53 Pathway
Thoracic Cancer 2025 April [Link] Susumu Kirimura, Morito Kurata, Hironori Ishibashi, Yusuke Taniguchi, Yuko Kinowaki, Keisuke Sugita, Kenichi Okubo Abstract Introduction: Chemotherapy is crucial for treating pleural mesothelioma; however, the outcomes are poor, necessitating an urgent need to study the mechanism of chemotherapy resistance in mesothelioma cells. Human antigen R (HuR), an RNA-binding protein and…
Read MoreUtility and limitations of Merlin immunohistochemistry for mesothelioma diagnosis in tissue sections and cell blocks
Annals of Diagnostic Pathology 2025 August [Link] Kazuki Nabeshima, Makoto Hamasaki, Tomomi Furukawa, Shinji Matsumoto, Katsumi Takizawa, Makiko Adachi, Yuko Goto Abstract Distinguishing pleural mesothelioma (PM) from reactive mesothelial proliferations (RMP) can be challenging. In such cases, immunohistochemistry (IHC)-detected BAP1 or MTAP loss and FISH-detected CDKN2A homozygous deletion are effective. Merlin is the protein product…
