International Journal of Molecular Sciences: Targeting Metabolic and Epigenetic Vulnerabilities in Glioblastoma with SN-38 and Rabusertib Combination Therapy (Penalva)

January 16, 2025

 Jennifer Chiou Valeria Impedovo Yen Bao Huynh ,Ruggiero Gorgoglione Luiz O. F. Penalva Alessia Lodi Andrew J. Brenner Stefano Tiziani Abstract Glioblastoma (GBM), the most prevalent primary malignant brain tumor, remains challenging to treat due to extensive inter- and intra-tumor heterogeneity. This variability demands combination treatments to improve therapeutic outcomes. A significant obstacle in treating [...]

Aging Cell: Age-Dependent Bi-Phasic Dynamics of Ly49+CD8+ Regulatory T Cell Population (Rao)

December 19, 2024

Saranya Srinivasan, Shruti Mishra, Kenneth Ka-Ho Fan, Liwen Wang, John Im, Courtney Segura, Neelam Mukherjee, Gang Huang, Manjeet Rao, Chaoyu Ma, Nu Zhang ABSTRACT Aging is tightly associated with reduced immune protection but increased risk of autoimmunity and inflammatory conditions. Regulatory T cells are one of the key cells to maintaining immune homeostasis. The age-dependent changes in CD4+Foxp3+ regulatory T cells (Tregs) have been well […]

SLAS Discovery: The History, Landscape, and Outlook of Human Cell Line Authentication and Security (Pertsemlidis)

November 20, 2024

 Elijah Harbut1,2,3 ∙ Yiorgos Makris4 ∙ Alexander Pertsemlidis5,6,7 ∙ Leonidas Bleris1,2,3 1 Introduction The phenomenon of cellular cross-contamination and misidentification (“CCCM”) was identified more than six decades ago and continues to pose significant challenges for laboratories globally. The prevalence of CCCM is alarmingly high, with estimates suggesting that up to 30% of cell lines may be misidentified, leading to substantial financial losses[2–4]. Accelerating progress in [...]

Molecular Oncology: Hijacking the BAF complex: the mechanistic interplay of ARID1A and EWS::FLI1 in Ewing sarcoma (Libich Lab)

October 3, 2024

 Erich J. Sohn, David S. Libich Abstract Ewing sarcoma, an aggressive pediatric cancer, is driven by the EWS::FLI1 fusion protein, which disrupts gene expression by hijacking the BAF chromatin remodeling complex. Central to this mechanism is the formation of biomolecular condensates, mediated by the prion-like domains (PrLDs) of EWS and ARID1A, a core BAF subunit. ARID1A serves [...]
