Sex Differences In Stress Reactivity, Brain Morphology, And Oxytocin In The Hypothalamus Of The Gray Short-Tailed Opossum (Monodelphis Domestica), Esperanza I. Zacarias, Daniela Rodriguez, Alexandra Chalons, Sasawan Heingraj, Nicole Altamirano, Joseph Rafac, John L. Vandeberg, Mario Gil

Research Colloquium

Understanding the effects of stress on behavior and cognition is important due to its impact on mental health and wellbeing (Schneiderman et al. 2005). Translational animal research can contribute to the development of new treatments that can improve therapeutic outcomes and our understanding of the neurobiology of stress. In the present study, we complement behavioral stress reactivity with immunohistochemical localization of oxytocin in the hypothalamus, a neuropeptide that regulates stress (Neumann & Slattery, 2016). Oxytocin has potential therapeutic use for mental health disorders (Neumann & Slattery, 2016), and the effects of oxytocin seem to be sexually dimorphic (Love, 2018). Using …

However, smart delivery systems that can improve the bioavailability and the delivery of multiple hydrophobic anti-cancer drugs simultaneously at the tumor site without normal organ toxicity could be an effective strategy for cancer treatment.

Methods: Here, a PEGylated drug-drug conjugate (CUR-PEG-S-S-CPT) have been successfully synthesized by conjugating two hydrophobic anti-cancer molecules, curcumin and camptothecin through …

Developing A Chlorophyll-Based Near-Infrared Fluorescent Probe For Cancer Cell Imaging, Benilde E. Adriano, Nycol M. Cotto, Neeraj Chauhan, Meena Jaggi, Subhash C. Chauhan, Murali M. Yallapu

Research Colloquium

Introduction: Near-Infrared (NIR) fluorescence-based imaging is a noteworthy and safer strategy for cancer cells/tissues imaging compared to radiological imaging. NIR fluorescence offers deep tissue penetration and have minimal obstruction by autofluorescence and photon scattering [1]. There are several NIR dyes including indocyanine green (ICG) [2] and IR-1061 [3] that allow high-resolution tissue imaging. However, these dyes possess some low-quality characteristics which limit their use, namely photo instability, toxicity, poor water solubility, and short half-lives [4]. Therefore, more efficient and effective alternatives are urgently required to provide the desired clinical outcomes. Chlorophyll (Chl) is a natural dietary NIR fluorescence emitting …

Seed Coatings Containing Capsaicin Reduce Seed Removal In Temperate Woody Species, Brian M. Connolly, Francesca Lanni, John L. Orrock, Peter W. Guiden

Biology Faculty Scholarship

Coating seeds in taste-averting chemical defenses (e.g., capsaicin from Capsicum spp.) can reduce rodent seed predation, and thus might promote plant establishment and forest regeneration. However, the efficacy of such seed coatings remains unknown for many woody plant species, and seed coatings have not been evaluated across different habitats where forest managers might seek to promote forest regeneration. We used two complementary seed-removal experiments in closed-canopy forests (Michigan) and an old field undergoing reforestation (New York) to examine whether coating seeds of four native tree species (Acer rubrum, Fagus grandifolia, Pinus banksiana, and Pinus resinosa) with chili …

An Intrinsically Disordered Region Controlling Condensation Of A Circadian Clock Component And Rhythmic Transcription In The Liver, Kun Zhu, Isaac J Celwyn, Dongyin Guan, Yang Xiao, Xiang Wang, Wenxiang Hu, Chunjie Jiang, Lan Cheng, Rafael Casellas, Mitchell A Lazar

Faculty, Staff and Students Publications

Circadian gene transcription is fundamental to metabolic physiology. Here we report that the nuclear receptor REV-ERBα, a repressive component of the molecular clock, forms circadian condensates in the nuclei of mouse liver. These condensates are dictated by an intrinsically disordered region (IDR) located in the protein's hinge region which specifically concentrates nuclear receptor corepressor 1 (NCOR1) at the genome. IDR deletion diminishes the recruitment of NCOR1 and disrupts rhythmic gene transcription in vivo. REV-ERBα condensates are located at high-order transcriptional repressive hubs in the liver genome that are highly correlated with circadian gene repression. Deletion of the IDR disrupts transcriptional …
