Overlaying single cell readouts of cell cycle and apoptosis onto a multidimensional analysis of pulsed cisplatin signalling dynamics reveals targetable mechanisms of platinum resistance in lung adenocarcinoma.
The Ras activator RasGRP1 that impacts Ras signals in immune cells, leukemias, and colorectal cancer, switches to an active conformation aided by a pH-sensitive histidine residue in a central location of the RasGRP1 molecule.
The major cytosolic yeast peroxiredoxin Tsa1 controls aging and H2O2-resistance by inhibiting protein kinase A through a conserved cysteine in the catalytic subunit activation loop and not by scavenging H2O2.
In response to tissue damage, reactive oxygen species can be sensed by cation channels TRPA1/RyR to cause increases of cytosolic Ca2+ in intestinal stem cells, activating Ras/MAPK activity and stimulating stem cell proliferation in Drosophila.
Mitochondrial-targeted SS-31 peptide ameliorates mitochondrial dysfunction and rescues pre-existing cardiac dysfunction in old mice, supporting the translational potential of mitochondrial protective interventions to treat age-related diseases.
Lipocalin-2 is a strong predictor of hunger scores, reflects an anti-obesity response that is deregulated in severely obese subjects, and exerts an anorexigenic function with a conserved interspecies mechanism.
