Chloride Intracellular Channel Proteins Respond To Heat Stress In Caenorhabditis Elegans, Jun Liang, Yakov Shaulov, Cathy Savage-Dunn, Stéphane Boissinot, Tasmia Hoque

Publications and Research

Chloride intracellular channel proteins (CLICs) are multi-functional proteins that are expressed in various cell types and differ in their subcellular location. Two CLIC homologs, EXL-1 (excretory canal abnormal like-1) and EXC-4 (excretory canal abnormal± 4), are encoded in the Caenorhabditis elegans genome, providing an excellent model to study the functional diversification of CLIC proteins. EXC-4 functions in excretory canal formation during normal animal development. However, to date, the physiological function of EXL-1 remains largely unknown. In this study, we demonstrate that EXL-1 responds specifically to heat stress and translocates from the cytoplasm to the nucleus in intestinal cells and body …

Maternal Hypothalamic-Pituitary-Adrenal Axis Response To Foraging Uncertainty: A Model Of Individual Vs. Social Allostasis And The "Superorganism Hypothesis", Jeremy D. Coplan, Nishant K. Gupta, Asif Karim, Anna Rozenboym, Eric L.P. Smith, John G. Kral, Leonard A. Rosenblum

Publications and Research

Introduction: Food insecurity is a major global contributor to developmental origins of adult disease. The allostatic load of maternal food uncertainty from variable foraging demand (VFD) activates corticotropin-releasing factor (CRF) without eliciting hypothalamic-pituitary-adrenal (HPA) activation measured on a group level. Individual homeostatic adaptations of the HPA axis may subserve second-order homeostasis, a process we provisionally term “social allostasis.” We postulate that maternal food insecurity induces a “superorganism” state through coordination of individual HPA axis response.

Methods: Twenty-four socially-housed bonnet macaque maternal-infant dyads were exposed to 16 weeks of alternating two-week epochs of low or high foraging demand shown to compromise …

The Farnesoid X Receptor Negatively Regulates Osteoclastogenesis In Bone Remodeling And Pathological Bone Loss, Ting Zheng, Ju-Hee Kang, Jung-Sun Sim, Jung-Woo Kim, Jeong-Tae Koh, Chan Soo Shin, Hyungsik Lim, Mijung Yim

Publications and Research

Farnesoid X receptor (FXR, NR1H4) is a member of the nuclear receptor superfamily of ligand-activated transcription factors. Since the role of FXR in osteoclast differentiation remains ill-defined, we investigated the biological function of FXR on osteoclastogenesis, using FXR-deficient mice. We demonstrated that FXR deficiency increases osteoclast formation in vitro and in vivo. First, FXR deficiency was found to accelerate osteoclast formation via down-regulation of c-Jun N-terminal kinase (JNK) 1/2 expression. Increased expression of peroxisome proliferator-activated receptor (PPAR)γ and peroxisome proliferator-activated receptor gamma coactivator 1 (PGC- 1)β seems to mediate the pro-osteoclastogenic effect of FXR deficiency via the JNK pathway. In …

State Reform And Respect For The Rights Of The Disabled People: A Reflection On The Olmstead Decision The Case Of New York State, Roseanne L. Flores

Publications and Research

Individuals with serious mental illness are often forced to live in institutional settings which limit their freedom and rights to become fully integrated into the community. The Olmstead v. L.C., 527 U.S. 581 (1999) decision ruled that states must provide individuals with disabilities the opportunity to live in the most integrated settings based on their needs. Since that time several lawsuits have been filed on behalf of individuals with disabilities against states for failing to comply with the Olmstead decision. New York State is one such state. The purpose of this paper is to describe the lawsuit which was brought …

Inflammation And Bone Mineral Density: A Mendelian Randomization Study, Jian V. Huang, C. Mary Schooling

Publications and Research

Osteoporosis is a common age-related disorder leading to an increase in osteoporotic fractures and resulting in significant suffering and disability. Inflammation may contribute to osteoporosis, as it does to many other chronic diseases. We examined whether inflammation is etiologically relevant to osteoporosis, assessed from bone mineral density (BMD), as a new potential target of intervention, or whether it is a symptom/biomarker of osteoporosis. We obtained genetic predictors of inflammatory markers from genome-wide association studies and applied them to a large genome wide association study of BMD. Using two-sample Mendelian randomization, we obtained unconfounded estimates of the effect of high-sensitivity C-reactive …

Coding Of Velocity Storage In The Vestibular Nuclei, Sergei B. Yakushin, Theodore Raphan, Bernard Cohen

Publications and Research

Semicircular canal afferents sense angular acceleration and output angular velocity with a short time constant of ≈4.5 s. This output is prolonged by a central integrative network, velocity storage that lengthens the time constants of eye velocity. This mechanism utilizes canal, otolith, and visual (optokinetic) information to align the axis of eye velocity toward the spatial vertical when head orientation is off-vertical axis. Previous studies indicated that vestibular-only (VO) and vestibular-pause-saccade (VPS) neurons located in the medial and superior vestibular nucleus could code all aspects of velocity storage. A recently developed technique enabled prolonged recording while animals were rotated and …
