A Traditional Chinese Medicine botanical drug exerts a competitive antagonism on the cAMP-induced modulation of sinoatrial node pacemaker channels and this functional inhibition reduces the slope of the diastolic depolarization hence spontaneous cell automaticity.

Structural and biochemical analysis of semisynthetic Akt forms and mutants has revealed the importance of a key interaction network involving Arg86, Glu17, and Tyr18 that controls Akt conformation and activity.

Specific inhibition of cyclin-dependent kinase-like 5 (CDKL5), a kinase linked to a severe neurodevelopmental disorder, demonstrates an important role in the regulation of excitatory hippocampal synapses and synaptic plasticity that was not previously appreciated in rodent knock-out models.

Single-molecule fluorescence experiments reveal transcription initiation proceeds via a 'bind-unwind-load-and-lock' mechanism where promoter DNA unwinds outside the RNA polymerase (RNAP) cleft, the unwound template-DNA loads into the cleft, and RNAP 'locks' the template-DNA by closing the RNAP clamp module.

Low expression of Cbfb may be the cause of osteoarthritis, and local admission of Cbfb may rescue and protect against osteoarthritis through decreasing Wnt/β-catenin signaling, and increasing Hippo/Yap signaling and Tgfβ/Smad2/3 signaling in osteoarthritis articular cartilage.

Mitochondrial fission, associated with fatty acids oxidation, is fundamental for AgRP neuronal activity during negative energy balance and in regulating fasting- and/or ghrelin-induced feeding.

Signalling and metabolic interactions of the plant energy organelles, chloroplasts and mitochondria, depend on the nuclear regulatory protein RCD1.

Regulatory T cells produce analgesic opioid peptides that limit heat sensitivity in mice, revealing a novel pain regulation mechanism independent of inflammation control.

Colored surfaces induce gamma oscillations in human early visual cortex that are equally strong for red and green colors when L-M cone contrast is controlled for.

Talaromyces (Tsp_PR) fungus render Aedes aegypti mosquitoes more susceptible to dengue virus infection through secreted molecules that impair midgut digestive enzyme transcription and activity.
