Summary: The study aimed to investigate the mechanism of cell death in breast and lung cancer cell lines treated with fractions derived from bitter melon extract. The results showed that the fractions reduced mitochondrial membrane potential and intracellular ATP levels, while increasing reactive oxygen species levels. However, they did not activate caspase-3 or release cytochrome c in the cancer cells, suggesting a different mechanism of cell death induction.

Summary: The combination of PDT and PTT shows significant therapeutic outcomes in cancer phototherapy. A new small-molecule mixed-ligand Ni(II)dithiolene complex, Ni-TDD, has been developed, which exhibits potent red-light PDT and near-infrared light PTT activity against cancer cells and 3D multicellular tumour spheroids (MCTSs).

Summary: Researchers have found that nickel oxide nanoparticles affect the exposed roots of Allium cepa by disrupting cell membranes and being internalized within cell organelles, leading to disturbances in cellular homeostasis and survival. This external intervention causes changes in the cellular environment, reflected in crucial biochemical profiles.

Summary: ROS are highly reactive molecules that regulate important signaling pathways. Tumor cells have altered redox balance compared to normal cells, making them susceptible to anti-tumoral therapy targeting ROS levels and antioxidant system capacity. Melatonin has potential as an innovative cancer treatment, but its mechanism of action remains unclear, limiting its clinical applications.

Summary: This study investigated the toxicity of microplastics on different cell lines and found that microplastics showed significant toxicity to THP-1 macrophages, with toxicity correlated to the generation potential of reactive oxygen species (ROS). Weathering process reduced the ROS generation potential of microplastics, as weathered microplastics had increased affinity to bind serum protein acting as ROS scavenger.

Summary: The relationship between mitophagy and ROS production is complex and not fully understood. This review discusses mtROS generation and their detrimental effects on cellular viability, along with the cellular defense mechanisms against oxidative stress. Furthermore, the prominent mechanisms governing mitophagy induction that bear on oxidative stress are explored.

Summary: This study investigated the protective mechanism of rutin in alleviating TEGDMA-induced toxicity in macrophages. Results showed that rutin substantially reduced cytotoxicity, apoptosis, and genotoxicity, and decreased oxidative stress and ROS generation caused by TEGDMA.

Summary: Pyraoxystrobin (SYP-3343), a newly-invented strobilurin fungicide, exhibits high toxicity to aquatic organisms, particularly in zebrafish embryos, through affecting cell cycle, mitochondrial membrane potential, and reactive oxygen species generation. This toxicity is dose- and time-dependent, inducing apoptosis in zebrafish embryos.

Summary: This study investigated the biological effects of ZnO nanosheets on embryonic bovine lung cells. The nanosheets caused morphological changes, oxidative stress, cell proliferation, and apoptosis in the cells. The concentration and time of exposure played important roles in the toxic effects of ZnO nanosheets on the cells.

Summary: Mitochondrial dysfunction and oxidative stress are associated with T cell-mediated autoimmune diseases, and targeting metabolic pathways can inhibit autoreactive T cell activation. Increasing the requirements of Tregs for ROS and oxidative phosphorylation can promote self-tolerance and inhibit the activity of autoreactive T cells.

Summary: Environmental surveillance-mediated behavior in Caenorhabditis elegans integrates multiple cues and is coordinated by neurons through signaling cascades. Despite lacking eyes, C. elegans is able to perceive and react to the color blue. This study explains this color perception by showing that internally-generated reactive oxygen species (ROS), in response to light, add to exogenous sources of ROS. Multiple sub-threshold sources of ROS are integrated to coordinate behavioral responses with internal cues. Blue light affects C. elegans behavior through ROS generation by endogenous flavins, mediated by the neuronal gustatory photoreceptor like protein, LITE-1. Overall, this study demonstrates that ROS and LITE-1 play central roles in C. elegans foraging behavior through integration of multiple inputs, including light.

Summary: Here we report the synthesis of a novel fluorescent probe P182 for quantitative measurement of H2O2. This fluorometric probe displays a fluorescence turn-on response in the presence of H2O2. It offers good performances in terms of sensitivity and response time, and shows non-toxic activity for in vivo studies. This study provides research on molecular fluorescence probe for the detection of H2O2.

Summary: A series of 4-anilinoquinolinylchalcone derivatives were synthesized and evaluated for their antiproliferative activities. Among them, compound 4a showed the highest cytotoxicity in breast cancer cells and low cytotoxicity in normal cells. Compound 4a caused ATP depletion, apoptosis, and ROS-dependent caspase 3/7 activation in breast cancer cells. These findings suggest that 4-anilinoquinolinylchalcone derivatives have potential as anticancer agents.

Summary: Sinularin was found to effectively inhibit the growth of hepatocellular carcinoma SK-HEP-1 cells at a concentration of 10 μM, inducing DNA fragmentation and apoptosis, as well as affecting cell migration and colony formation. Additionally, it altered the expression levels of various proteins related to cell signaling and metastasis.
