The role of the mitochondrial electron transport chain (ETC) in regulating ferroptosis is not fully elucidated. Here, we reveal that pharmacological inhibition of the ETC complex I reduces ubiquinol levels while decreasing ATP levels and activating AMP-activated protein kinase (AMPK), the two effects known for their roles in promoting and suppressing ferroptosis, respectively. Consequently, the impact of complex I inhibitors on ferroptosis induced by glutathione peroxidase 4 (GPX4) inhibition is limited. The pharmacological inhibition of complex I in LKB1-AMPK-inactivated cells, or genetic ablation of complex I (which does not trigger apparent AMPK activation), abrogates the AMPK-mediated ferroptosis-suppressive effect and sensitizes …

RNA transcribed from enhancers, i.e., eRNA, has been suggested to directly activate transcription by recruiting transcription factors and co-activators. Although there have been specific examples of eRNA functioning in this way, it is not clear how general this may be. We find that the AT-hook of SWI/SNF preferentially binds RNA and, as part of the esBAF complex, associates with eRNA transcribed from intronic and intergenic regions. Our data suggest that SWI/SNF is globally recruited in cis by eRNA to cell-type-specific enhancers, representative of two distinct stages that mimic early mammalian development, and not at enhancers that are shared between the …


Parkinson's Disease - Association With Anxiety, Depression, And Sleep Disorders, Isabella J. Boroje May 2024

Parkinson's Disease - Association With Anxiety, Depression, And Sleep Disorders, Isabella J. Boroje

Doctoral Dissertations and Projects

Parkinson’s disease (PD) is a progressive neurological disorder presenting with motor symptoms, such as tremors at rest, bradykinesia, rigidity, and gait instability, and non-motor symptoms, such as anxiety, depression, excessive daytime sleepiness (EDS), and REM Sleep Behavior Disorder (RBD). The purpose of this study was to examine the associations of anxiety, depression, and EDS scores with being Prodromal (PPD) - at risk of developing the disease (PPD), having been diagnosed with PD, or being a Healthy Control (HC) using a multinomial logistic regression model. Additional analysis examined RBD scores and their difference across PPD, PD, and HC cohorts. The study …

BRG1 (SMARCA4) and BRM (SMARCA2) are the mutually exclusive core ATPases of the chromatin remodeling BAF (BRG1/BRM-associated factor) complexes. They enable transcription factors/cofactors to access enhancers/promoter and modulate gene expressions responsible for cell growth and differentiation of acute myeloid leukemia (AML) stem/progenitor cells. In AML with MLL1 rearrangement (MLL1r) or mutant NPM1 (mtNPM1), although menin inhibitor (MI) treatment induces clinical remissions, most patients either fail to respond or relapse, some harboring menin mutations. FHD-286 is an orally bioavailable, selective inhibitor of BRG1/BRM under clinical development in AML. Present studies show that FHD-286 induces differentiation and lethality in AML cells with …

Explaining The Staircase Gelb Illusion, Simultaneous Contrast, And Perceptual Fading Of Stabilized Images With A Neural Model Driven By Fixational Eye Movements, Michael E. Rudd May 2024

Explaining The Staircase Gelb Illusion, Simultaneous Contrast, And Perceptual Fading Of Stabilized Images With A Neural Model Driven By Fixational Eye Movements, Michael E. Rudd

MODVIS Workshop

A neural model of lightness computation driven by fixational eye movements is described and used to simulate various lightness phenomenon, including the Staircase Gelb illusion and its variants, simultaneous contrast, the Chevreul illusion, and perceptual fading of stabilized images. The model provides a precise account of the lightness matches from several experiments, with an overall error of only 1.5%. In the model, spatial maps of transient ON and OFF cell activations—produced as the eyes traverse the visual scene—are sorted by eye movement direction in visual cortex. At a subsequent processing stage, the activations within these maps are summed across space …

The Palestinian Feature Film "200 Meters" Addresses The Issue Of The Apartheid Wall, Samar Abd Al Karim Farahat

Middle East Journal of Communication Studies

This study aimed to explain the methods of processing the Palestinian feature film" 200 meters " to the issue of the apartheid wall, using sub-objectives highlighting political, social and psychological issues and topics in addition to the characters and cinematic elements, to identify the form of processing carried out by the film in an integrated manner. Given the nature of this study, which aimed to find out how the 200-meter film dealt with the issue of the apartheid wall, the researcher adopted the most appropriate approach to studying this type of phenomena, which is the analytical approach. The results of …
