Development Of A Structurally Distinct Topbp1 Inhibitor That Enhances Parp Blockade And Reverses Osimertinib Resistance, Fang-Tsyr Lin, Shwu-Jiuan Lin, Kang Liu, Yang Xiao, Lidija A Wilhelms Garan, Helena Folly-Kossi, Weei-Chin Lin

Faculty, Staff and Students Publications

Therapeutic resistance remains a major challenge in cancer treatment, driven by compensatory signaling and stress response pathways that sustain tumor survival. Topoisomerase IIβ-binding protein 1 (TopBP1), a multifunctional scaffold protein with nine BRCT domains, integrates replication stress signaling with oncogenic networks and is frequently overexpressed in aggressive cancers. Its BRCT7/8 domains mediate critical interactions with E2F1, mutant p53, MIZ1, PLK1, and CIP2A, making TopBP1-BRCT7/8 an attractive therapeutic target. Using docking-guided screening and structure-activity relationship–driven optimization, we developed CS18 as a potent and selective BRCT7/8 inhibitor that disrupts oncogenic TopBP1 complexes without interfering with DNA replication. CS18 suppresses MYC transcriptional programs, …

Development Of Minimalist Trifunctional Building Blocks For Chemical Biology Probe Synthesis, Luke E. Bohrer

Electronic Theses and Dissertations

The completion of the Human Genome Project in 2003 generated expectations that genomic information would accelerate the discovery of new protein drug targets and FDA-approved therapies. However, many small-molecule drug candidates continue to fail in clinical trials, and much of the human proteome remains undercharacterized in terms of structure, function, and disease relevance. Chemical tools are therefore essential for defining protein function, mapping protein interactions, and identifying disease-associated molecular mechanisms. Among these tools, small-molecule chemical probes provide a powerful strategy for connecting biological activity with target identification, functional analysis, and the development of effective therapies.

Empathetic Political Communication As The Political Identity Of Female Legislators: A Phenomenological Study In The Surabaya City Dprd, Nurannafi Farni Syam Maella, Farida Farida, Herlina Harsono Njoto, Hamizah Sahharon, Vinna Amalia

JURNAL KOMUNIKASI INDONESIA

Politics has long been constructed as a masculine arena dominated by discourses of power, authority, and instrumental rationality. The presence of female legislators disrupts this hegemony by foregrounding empathetic modes of political communication that emphasize inclusivity, relational engagement, and responsiveness to social realities. These communicative practices not only contest dominant masculine norms in political discourse but also expand deliberative spaces and support the formulation of gender-responsive public policies. Accordingly, this study examines how female legislators in the Surabaya Legislative Council construct and enact empathetic political communication as a core expression of their political identity. Using a qualitative phenomenological approach, this …

Electrocatalytic Oxidation Of Ethylene Glycol To Glycolic Acid: From Mechanism And Catalyst Design To Emerging Neutral Electrolyte Systems, Man Zhang, Xue Li, Xinyu Peng, Lin Wang, Wenwen Chen, Yaoyue Yang

Online First

Polyethylene terephthalate (PET) waste represents both an environmental burden and a loss of carbon resources. Alkaline depolymerization of PET yields terephthalic acid and ethylene glycol (EG). Electrocatalytic oxidation of EG to glycolic acid (GA), the monomer of biodegradable polyglycolic acid (PGA), offers a sustainable route driven by renewable electricity. However, the ethylene glycol oxidation reaction (EGOR) involves competing pathways toward C2 products (GA and oxalic acid) and C1 products (formic acid and CO₂), making selective GA production a central challenge. This review provides a comprehensive overview of recent progress in selective EG-to-GA electrooxidation from catalyst design, mechanistic understanding, …

Reducing Hospital-Acquired Pressure Injuries In Acute Care Using Structured Prevention Strategies, Yemisi Adesuyi Akinfenwa

Walden Dissertations and Doctoral Studies

Pressure injuries that patients develop while hospitalized continue to be a major safety concern in hospitals treating very sick patients. These wounds hurt, make infections more likely, keep people in the hospital longer, and increase expenses. On many units, the steps meant to stop these injuries, like checking each patient's risk level and turning patients regularly are not carried out the same way for everyone. Because of this inconsistency, some patients develop preventable pressure injuries. The purpose of this Doctor of Nursing Practice (DNP) project was to create a clinical practice guideline (CPG) for organized pressure injury prevention and to …

Genotypic Triggers: Exposing Pharmacogenomic Blind Spots Via Host-Specific Backdoors In Generative Antimicrobial Peptide Models, Doniyorkhon Obidov, Xiaolong Guo, Yonghui Li, Kaichen Yang

Michigan Tech Publications

Large Language Models (LLMs) have accelerated drug discovery, particularly in the automated design of antimicrobial peptides (AMPs). However, current validation pipelines for peptide generation models overlook historical precedents showing that certain drugs carry health risks predominantly for individuals with specific genetic profiles. In this paper, we demonstrate that such targeted health risks can be induced intentionally and at scale by manipulating models that generate peptide candidates. We introduce the Genotypic Trigger, a backdoor attack that shifts a model’s generative distribution toward peptides with elevated predicted immunogenicity risk, an adverse immune reaction, specifically for carriers of a tar- geted HLA allele, …
