Scientific Reports: A CIC-related-epigenetic factors-based model associated with prediction, the tumor microenvironment and drug sensitivity in osteosarcoma (Kitagawa Lab)

January 16, 2024

Bin Yu, Chengkui Geng, Zhongxiong Wu, Zhongzi Zhang, Aili Zhang, Ze Yang, Jiazheng Huang, Ying Xiong, Huiqin Yang & Zhuoyuan Chen Abstract Osteosarcoma is generally considered a cold tumor and is characterized by epigenetic alterations. Although tumor cells are surrounded by many immune cells such as macrophages, T cells may be suppressed, be inactivated, or not [...]

MDPI Cells: Survivin-Sodium Iodide Symporter Reporter as a Non-Invasive Diagnostic Marker to Differentiate Uterine Leiomyosarcoma from Leiomyoma (Bishop Lab)

January 10, 2024

Natalia Garcia 1,2,†,Mara Ulin 1,3,†,Qiwei Yang 1,4ORCID,Mohamed Ali 1,4,5ORCID,Maarten C. Bosland 6,Weiqiao Zeng 1,Liaohai Chen 1 andAyman Al-Hendy 1,4, Abstract Leiomyosarcoma (LMS) has been challenging to diagnose because of limitations in clinical and radiographic predictors, as well as the lack of reliable serum or urinary biomarkers. Most uterine masses consist of benign leiomyoma (LM). However, [...]

Scientific Reports: Associations of tissue damage induced inflammatory plasticity in masseter muscle with the resolution of chronic myalgia (Lai)

January 4, 2024

Abstract Gene plasticity during myogenous temporomandibular disorder (TMDM) development is largely unknown. TMDM could be modeled by intramuscular inflammation or tissue damage. To model inflammation induced TMDM we injected complete Freund’s adjuvant (CFA) into masseter muscle (MM). To model tissue damage-induced TMDM, we injected extracellular matrix-degrading collagenase type 2 (Col). CFA and Col produced distinct [...]

Nucleic Acids Research: The protein phosphatase EYA4 promotes homologous recombination (HR) through dephosphorylation of tyrosine 315 on RAD51 (Sung Lab)

December 14, 2023

Bárbara de la Peña Avalos, Nicolas Paquet, Romain Tropée, Yan Coulombe, Hannah Palacios, Justin W Leung, Jean-Yves Masson, Pascal H G Duijf, Eloïse Dray Abstract Efficient DNA repair and limitation of genome rearrangements rely on crosstalk between different DNA double-strand break (DSB) repair pathways and their synchronization with the cell cycle. The selection, timing, and efficacy of DSB repair pathways are influenced by post-translational modifications of histones and [...]
