Genes & Cancer: Roles of USP1 in Ewing sarcoma (Shiio Lab)

February 13, 2024

 Panneerselvam Jayabal1, Xiuye Ma1 and Yuzuru Shiio1,2,3 ABSTRACT Ewing sarcoma is a cancer of bone and soft tissue in children and young adults that is driven by the EWS-ETS fusion transcription factor, most commonly EWS-FLI1. We previously reported that Ewing sarcoma harbors two populations of cells, the CD133high population displaying higher growth rate and the CD133low population displaying [...]

Cancers: The Versatile Attributes of MGMT: Its Repair Mechanism, Crosstalk with Other DNA Repair Pathways, and Its Role in Cancer (Sung Lab)

February 5, 2024

 by  Qingming Fang Simple Summary This review offers a thorough examination of the potential role and structural properties of MGMT, the progression in targeting MGMT, and the interactions between MGMT and DNA repair pathways involved in processing DNA lesions. Abstract O6-methylguanine-DNA methyltransferase (MGMT or AGT) is a DNA repair protein with the capability to remove [...]

Genetic Counseling: Families’ experiences accessing care after genomic sequencing in the pediatric cancer context: “It’s just been a big juggle” (Tomlinson)

January 18, 2024

 Blake Vuocolo, Amanda M. Gutierrez, Jill O. Robinson, Alva M. Recinos, Lauren R. Desrosiers, Mary A. Majumder, Juan Carlos Bernini, Jonathan Gill, Timothy Griffin, Gail E. Tomlinson, Kelly Vallance, Amy L. McGuire, D. Williams Parsons, Sharon E. Plon, Sarah Scollon Abstract Access to genomic sequencing (GS) and resulting recommendations have not been well described in pediatric oncology. GS results may provide a cancer predisposition syndrome (CPS) diagnosis that warrants [...]

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 [...]
