Although the heat-stress response has been extensively studied for decades, very little is known about its effects on nucleic acids and nucleic acid-associated processes. This is due to the fact that the research has focused on the study of heat shock proteins and factors (HSPs and HSFs), their involvement in the regulation of transcription, protein homeostasis, etc. Recently, there has been some progress in the study of heat stress effects on DNA integrity. In this review, we summarize and discuss well-known and potential mechanisms of formation of various heat stress-induced DNA damage.

Living organisms are continuously exposed to a myriad of DNA damaging agents that can impact health and modulate disease-states. However, robust repair damage-bypass mechanisms faithfully protect the by either removing or tolerating damage ensure an overall survival. Deviations in this fine-tuning known destabilize cellular metabolic homeostasis, as exemplified diverse cancers where disruption deregulation pathways results genome instability. Because routinely used biological, physical chemical human health, testing their genotoxicity regulating use have become important.

GC pairs are generally more stable than AT pairs; GC-rich genomes were proposed to be adapted high temperatures AT-rich genomes. Previous studies consistently showed positive correlations between growth temperature and the contents of structural RNA genes. However, for whole genome sequences silent sites codons in protein-coding genes, relationship content is a long-lasting debate.

Cell Painting assays generate morphological profiles that are versatile descriptors of biological systems and have been used to predict in vitro vivo drug effects. However, features extracted from classical software such as CellProfiler based on statistical calculations often not readily biologically interpretable. In this study, we propose a new feature space, which call BioMorph, maps these with readouts comprehensive Health assays. We validated the resulting BioMorph space effectively connected compounds only associated their bioactivity but deeper insights into phenotypic characteristics cellular processes given bioactivity.

In all aspects, exposure to hyperthermia was shown higher therapeutic effect than therapy alone. However, it is ultimately consequence that results significant death rat glioma C6 cells. Excitation cells laser observed create cellular environment which enhanced efficiency hyperthermia, resulting remarkable anticancer mediated by ROS-dependent apoptosis via pathway.
