Polymerizing Actin Regulates Myosin-Independent Mechanosensing By Modulating Actin Elasticity And Flow Fluctuation, Nikhil Mittal, Etienne Michels, Kathleen Pakenas, Shaina P. Royer-Weeden, Sangyoon J. Han

Michigan Tech Publications

The stiffness of the extracellular matrix induces differential tension within integrin-based adhesions. However, it has been unclear if the stiffness-dependent differential tension is induced solely by myosin activity. Here, we report that in the absence of myosin contractility, 3T3 fibroblasts still transmit stiffness-dependent differential levels of traction. This myosin-independent differential traction is regulated by polymerizing actin assisted by actin nucleators Arp2/3 and formin where formin has stronger contribution than Arp2/3. Interestingly, we report a four-fold reduction in traction of cells when both Arp2/3 and myosin were inhibited, compared to cells with only myosin inhibition, while there was only a slight …

Photocatalytic oxidizing (PCO) air cleaners are offered for the abatement of gaseous pollutants (i.e., Volatile Organic Compounds or VOCs). However, due to a lack of testing standards, the overall characterization of the technology's effectiveness has been met with conflicting results. Different studies use varying experimental setups, test conditions, and different PCO air cleaner designs. According to the literature, the majority of testing has been in controlled laboratory setups with favorable conditions. As PCO air cleaner testing is scaled up to more realistic environments and conditions, the PCO removal efficiency tends to significantly decrease. The differences in removal efficiency can be …

Yap Mechanotransduction Under Cyclic Mechanical Stretch Loading For Mesenchymal Stem Cell Osteogenesis Is Regulated By Rock, Eunju Kim, Brandon D. Riehl, Tasneem Bouzid, Ruiguo Yang, Bin Duan, Henry J. Donahue, Jung Yul Lim

Department of Mechanical and Materials Engineering: Faculty Publications

While yes-associated protein (YAP) is now recognized as a potent mechanosensitive transcriptional regulator to affect cell growth and differentiation including the osteogenic transcription of mesenchymal stem cells (MSCs), most studies have reported the YAP mechanosensing of static mechanophysical cues such as substrate stiffness. We tested MSC response to dynamic loading, i.e., cyclic mechanical stretching, and assessed YAP mechanosensing and resultant MSC osteogenesis. We showed that cyclic stretching at 10% strain and 1 Hz frequency triggered YAP nuclear import in MSCs. YAP phosphorylation at S127 and S397, which is required for YAP cytoplasmic retention, was suppressed by cyclic stretch. We also …

Inclusive Counterfactual Generation: Leveraging Llms In Identifying Online Hate, M. Atif Qureshi, Arjumand Younus, Simon Caton

Articles

Counterfactually augmented data has recently been proposed as a successful solution for socially situated NLP tasks such as hate speech detection. The chief component within the existing counterfactual data augmentation pipeline, however, involves manually flipping labels and making minimal content edits to training data. In a hate speech context, these forms of editing have been shown to still retain offensive hate speech content. Inspired by the recent success of large language models (LLMs), especially the development of ChatGPT, which have demonstrated improved language comprehension abilities, we propose an inclusivity-oriented approach to automatically generate counterfactually augmented data using LLMs. We show …
