Are there changes of gene expression related to mechanotransduction and stress response under s-µG condition? 


Best insight from top research papers

Changes in gene expression related to mechanotransduction and stress response have been observed under simulated microgravity (s-µG) conditions. Studies have shown that microgravity affects genes involved in circadian clocks, mechanotransduction pathways, immune response, metabolism, and cell proliferation . Additionally, the response to mechanical stress in living organisms includes upregulation of genes involved in stress response, cuticle development, and signaling pathways such as WNT, TGFβ, AMPK, and Hedgehog signaling . Furthermore, the nuclear architecture and cytoskeleton play a role in mechanotransduction, with alterations in nuclear stiffness and nuclear remodeling influencing gene expression and cell fate . Actin remodeling, regulated by the Rho/Rho-kinase signaling pathway, has been shown to control gene expression in response to mechanical stimuli . These findings suggest that changes in gene expression related to mechanotransduction and stress response occur under s-µG conditions, highlighting the importance of understanding the molecular mechanisms involved in adapting to altered gravitational forces.

How do specific genes respond to different types of cellular stress?5 answersSpecific genes respond differently to various types of cellular stress through distinct transcription factors and signaling pathways. Cellular stress triggers rapid adaptation mechanisms, leading to changes in gene expression at multiple levels, including chromatin structure, transcription, mRNA stability, and translation. Studies have shown that stress-responsive genes can be identified and classified more accurately using machine learning models that integrate time-series transcriptome data from different stress types. Furthermore, in response to stress, genes can alter their interactions with other genes, forming stress-specific coexpression networks that are associated with disease pathways. Overall, the cellular stress response is a highly regulated process involving intricate gene regulatory mechanisms that ensure cell survival and adaptation.

Are modifications of mRNA a stress response?4 answersModifications of mRNA, particularly N6-methyladenosine (m6A), have been shown to play a role in the stress response in plants. RNA modifications, including m6A, have been implicated in cellular stress responses and diseases in various contexts and cell types. In bacteria, RNA modifications have been found to affect the bacterial response to sub-MIC antibiotics and are critical factors involved in the bacterial response to stress. Additionally, in the gut commensal and opportunistic pathogen Enterococcus faecalis, an ROS-sensing RNA-modifying enzyme has been discovered, which regulates translation of stress-response proteins. While the role of mRNA modifications in stress response in the heart is not explicitly mentioned, post-transcriptional alteration of mRNA levels has been identified as a driver of heart disease. Therefore, modifications of mRNA have been shown to be involved in stress responses in plants, bacteria, and potentially in heart disease.
How do cellular molecular changes from stress disorders?5 answersChronic stress can lead to cellular and molecular changes in the brain, which can contribute to the pathophysiology of stress disorders such as major depressive disorder (MDD) and posttraumatic stress disorder (PTSD). These changes can affect neural plasticity, synaptic transmission, and cognitive functions, particularly in memory-related brain regions like the hippocampus, amygdala, and prefrontal cortex. Stress can alter dendritic arborization, dendritic spine density, and glutamatergic-mediated synaptic transmission, which can impair long-term memory formation. Additionally, stress can modulate neurotransmitter signaling, microRNA expression, and glial activity in the brain, further contributing to memory impairment and cognitive decline. In the context of major depressive disorder, altered excitation-inhibition balance (EIB) in cortical brain regions has been observed, involving changes in GABAergic and glutamatergic signaling, as well as impaired pyramidal cell dendritic morphology and decreased somatostatin-cell function. These findings highlight the complex cellular and molecular mechanisms underlying stress disorders and their impact on brain function.
