Undergraduate degree programs named “Physiology” have existed for over 50 yr. The number of programs and enrolled students have been growing since ~2005 (5, 9). There are many thousands of students currently enrolled in physiology pro- grams across the United States and indeed across the world. Despite the long history and current popularity of the physiol- ogy major, there is no coordinated plan articulated for the design, administration, or assessment of degree programs in physiology at the undergraduate level.

Although several professional societies have invested in under- graduate physiology education in various ways, none has under- taken the task of …

Characterization Of Mechanotransduction In Annulus Fibrosus Cells, Min Kyu M. Kim 2020 The University of Western Ontario

Characterization Of Mechanotransduction In Annulus Fibrosus Cells, Min Kyu M. Kim

Electronic Thesis and Dissertation Repository

IVD degeneration is a multifactorial pathological process associated with back pain. While biomechanical factors are important regulators of IVD homeostasis, mechanical loading also contribute to the onset of IVD degeneration. Importantly, the mechanotransduction pathways that mediate cell type-specific responses to mechanical loading are not well understood. Transient receptor potential vanilloid 4 (TRPV4) is a multimodally activated cell surface cation channel implicated as a mechanoreceptor regulating the mechano-response in other musculoskeletal cell types. Using both in vitro and in vivo models, the current study aimed to characterize the role of TRPV4 in annulus fibrosus (AF) cell mechanotransduction. Using a mechanically dynamic …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Bacterial oxidative stress responses are generally controlled by transcription factors that modulate the synthesis of RNAs with the aid of some sRNAs that control the stability, and in some cases the translation, of specific mRNAs. Here, we report that oxidative stress additionally leads to inactivation of tRNAGly in Escherichia coli, inducing a series of physiological changes. The observed inactivation of tRNAGly correlated with altered efficiency of translation of Gly codons, suggesting a possible mechanism of translational control of gene expression under oxidative stress. Changes in translation also depended on the availability of glycine, revealing a mechanism whereby bacteria …
