Biomolecular NMR Assignments : The 1H, 15N and 13C backbone resonance assignments of an intrinsically disordered region (467–696) of breast cancer type 1 susceptibility protein (BRCA1) (Sung, Libich)

October 1, 2026

 Hoang H. Dinh, Angela M. Jasper, Antoine Baudin, Patrick Sung & David S. Libich The tumor suppressor protein breast cancer type 1 susceptibility protein (BRCA1) plays a central role in maintaining genome stability through its involvement in DNA damage repair, transcriptional regulation, and cell-cycle control. BRCA1 functions as an obligate heterodimer with its binding partner, [...]

Cell Reports: EWSR1::FLI1 promotes neocentromere formation in Ewing sarcoma cells (Zheng, Sung Lab, Kitagawa Lab)

August 17, 2026

 Risa Kitagawa1,2 ∙ Ediri E. Metitiri1,2 ∙ Bin Yu1,2 ∙ Changxian Shen1,2,6 ∙ Alexander J.R. Bishop1,3,5 ∙ Siyuan Zheng1,4 ∙ Peter J. Houghton1,2 ∙ Katsumi Kitagawa1,2,7 Send email to kitagawak@uthscsa.edu Highlights Summary Ewing sarcoma (EwS) is characterized by chimeric fusions such as EWSR1::FLI1. Chromosome gain or loss is prevalent in EwS, and this chromosome instability (CIN) phenotype correlates with poor treatment outcomes. We previously showed that CENP-A, a centromere-specific histone H3 variant, interacts with EWSR1 via its SYGQ2 motif, an [...]

International Journal of Molecular Sciences: Biogenic Metal Nanoparticles from Indian Flora as Programmable Bio-Interfaces: From Phytochemical Coronas to Precision Nanomedicine (Wasmuth Lab)

August 3, 2026

 Sharad Shriram Tat Kailas D. Datkhile Jayant R. Pawar Amar R. Mohite Tanisha Sharma Abstract Biogenic metal nanoparticles are naturally covered with the phytochemical corona, which includes plant-derived metabolites. Emerging evidence suggests that the phytochemical corona, together with the intrinsic properties of the metallic core, contributes significantly to the biological identity, therapeutic behavior, and safety [...]

Function: Constitutive mTORC1 Activation in Skeletal Muscle Increases Inflammation but is not Sufficient to Impair Glucose Tolerance (Lai Lab)

July 23, 2026

 Erik D. Marchant, Hanna Kalenta, Sean P. Kilroe, Jacquelyn May, Wenjun Z. Martini, Korri S. Weldon, Zhao Lai, and Blake B. Rasmussen  Abstract Aberrant mechanistic target of rapamycin complex 1 (mTORC1) signaling in skeletal muscle has been implicated in aging and insulin resistance; however, it is not known whether chronic mTORC1 activation directly causes glucose intolerance. We tested the hypothesis that constitutive mTORC1 activation in mouse skeletal muscle impairs glucose [...]

Nature Communications: Break-induced replication forms long mutable single-strand DNA during meiosis (Malkova)

June 22, 2026

 Thanks to advances in treatment, more than 85% of children diagnosed with cancer now survive into adulthood. However, many survivors face long-term health challenges caused by their cancer treatments, including heart disease, diabetes, high blood pressure, anxiety, depression, and reduced quality of life. In this study, researchers followed more than 18,000 childhood cancer survivors over [...]
