Mechanism and effects of pulsatile GABA secretion from cytosolic pools in the human beta cell

Steinunn Baekkeskov Hanahan, Chiara Cianciaruso, Petra Catalina Schwalie, Edward Allen Phelps

Pancreatic beta cells synthesize and secrete the neurotransmitter GABA (gamma-aminobutyric acid) as a paracrine and autocrine signal to help regulate hormone secretion and islet homeostasis. Islet GABA release has classically been described as a secretory- ...

Stimulus-induced modulation of transcriptional bursting in a single mammalian gene

Felix Naef, Benjamin Zoller, David Michael Suter, Rosamaria Cannavo

Mammalian genes are often transcribed discontinuously as short bursts of RNA synthesis followed by longer silent periods. However, how these "on" and "off" transitions, together with the burst sizes, are modulated in single cells to increase gene expressio ...
