Hsp90 and Isoform-Selective Inhibitors as Sensitizers for Cancer Immunotherapy.

Pharmaceuticals (Basel)

July 2025

Department of Biological Sciences, Boler-Parseghian Center for Rare Diseases, Harper Cancer Research Institute, University of Notre Dame, Notre Dame, IN 46556, USA.

The 90 kDa heat shock proteins (Hsp90) are molecular chaperones that regulate the stability and maturation of numerous client proteins implicated in the regulation of cancer hallmarks. Despite the potential of -Hsp90 inhibitors as anticancer therapeutics, their clinical development has been hindered by on-target toxicities, particularly ocular and cardiotoxic effects, as well as the induction of pro-survival, compensatory heat shock responses. Together, these and other complications have prompted the development of isoform-selective Hsp90 inhibitors.

MicroRNAs (miRNAs) are small non-coding RNA molecules that modulate gene expression and are essential in numerous biological functions, including reproductive functions. Alterations in miRNA expression can affect ovarian function, sperm development, and implantation processes, potentially leading to different diseases and consequently infertility. Researches have indicated that certain microRNAs play a crucial role in the regulation of hormones and proteins that are vital for reproductive processes, suggesting that dysregulation of these miRNAs may contribute to infertility in both men and women.

Fidelity of Next-Generation Sequencing to Predict Human Epidermal Growth Factor 2 Overexpression Across Solid Tumors.

JCO Precis Oncol

July 2025

Department of Hematology/Oncology, Indiana University Melvin and Bren Simon Comprehensive Cancer Center, Indiana University School of Medicine, Indianapolis, IN.

Purpose: Human epidermal growth factor 2 (HER2/ERBB2) has recently become a pan-tumor-agnostic target after the approval of trastuzumab deruxtecan for solid tumors with HER2 overexpression (3+). HER2 positivity is currently assessed by immunohistochemistry (IHC) and/or amplification through in situ hybridization (ISH), owing to the fact that HER2 overexpression is secondary to HER2 gene amplification in many cases. Outside of breast/gastroesophageal cancer, the optimal IHC scoring method to assess overexpression across solid tumors remains undefined.

Neurofibromatosis type 1 (NF1) is a genetic disorder caused by mutations of the NF1 tumor suppressor gene resulting in the loss of function of neurofibromin, a GTPase-activating protein (GAP) for Ras. While the malignant manifestations of NF1 are associated with loss of heterozygosity of the residual WT allele, the nonmalignant neurodevelopmental sequelae, including autism spectrum disorder (ASD) and/or attention deficit hyperactivity disorder (ADHD) are prevalent morbidities that occur in the setting of neurofibromin haploinsufficiency. We reasoned that augmenting endogenous levels of WT neurofibromin could serve as a potential therapeutic strategy to correct the neurodevelopmental manifestations of NF1.

Modulating hormonally upregulated neu-associated kinase (HUNK) activity in breast cancer: The development of HUNK inhibitors.

J Pharmacol Exp Ther

July 2025

Department of Pharmacology and Toxicology, Indiana University School of Medicine, Indianapolis, Indiana; Indiana University Melvin and Bren Simon Comprehensive Cancer Center, Indianapolis, Indiana. Electronic address:

Hormonally upregulated neu-associated kinase (HUNK) is a serine/threonine protein kinase in the sucrose non-fermenting 1/AMP-activated protein kinase family that promotes cell survival and plays an important role in breast cancer growth and metastasis. Robust methods to alter HUNK expression and activity are currently in use to advance our understanding of this kinase and its function. However, despite its role in the aggressive triple-negative cancer and human epidermal growth factor receptor 2 (HER2)+ breast cancer subtypes, targeted pharmacological inhibition of HUNK is still in its infancy.

Trends Immunol

July 2025

Department of Microbiology and Immunology, Indiana University Cooperative Center of Excellence in Hematology, Indiana University Melvin and Bren Simon Comprehensive Cancer Center, Indiana University School of Medicine, Indianapolis, IN, USA. Electronic address:

Active regulation of T cell quiescence is important to sustain immune responses to vaccination and infection while preventing inappropriate responses such as autoimmunity. Recent studies highlight that quiescence in naïve T cells is actively regulated by transcription factors and tonic signaling. Loss of quiescence in aged T cells has significant consequences because the cells are less responsive to infection or vaccination.

Mod Pathol

May 2025

Division of Computational Pathology, Department of Pathology and Laboratory Medicine, Indiana University School of Medicine, Indianapolis, Indiana; Indiana University Melvin and Bren Simon Comprehensive Cancer Center, Indianapolis, Indiana; Department of Neurological Surgery, Indiana University Scho

Glioblastoma (GBM) is the most common and aggressive malignant adult tumor of the central nervous system, with a grim prognosis and heterogeneous morphologic and molecular profiles. Since the adoption of the current standard-of-care treatment in 2005, no substantial prognostic improvement has been noticed. In this study, we seek the identification of prognostically relevant GBM characteristics from routinely acquired hematoxylin and eosin-stained whole slide images (WSIs) and clinical data, which when integrated via advanced computational methods could yield improved patient prognostic stratification and hence optimize clinical decision making and patient management.

Mitochondrial coupling efficiency and myofiber type related to blood pressure 22 h after high-intensity exercise in premenopausal women.

Eur J Appl Physiol

May 2025

Department of Nutrition Sciences, School of Health Professions, University of Alabama at Birmingham, 1675 University Blvd, Susan Mott Webb Building Suite 439, Birmingham, AL, 35233, USA.

Previously we have shown that systolic blood pressure (SBP) increases in African American (AA) women but decreases in European American (EA) women ≈22 h after a high-intensity exercise bout, suggesting delayed recovery in the AA women. We, therefore, sought to determine whether myofiber type, systemic vascular resistance (SVR), and mitochondrial coupling efficiency may contribute to elevated blood pressure in AA women following a bout of high-intensity exercise. Premenopausal EA (9) and AA (7) women were aerobically trained for 8-16 weeks and was evaluated.
