Extracellular signals regulate protein translation in many cell functions. A key advantage of control at the translational level is the opportunity to regulate protein synthesis within specific cellular subregions. However, little is known about mechanisms that may link extracellular cues to translation with spatial precision. Here, we show that a transmembrane receptor, DCC, forms a binding co...

Initiation of DNA synthesis in confluent quiescent 3T3 cell cultures stimulated by epidermal growth factor (EGF), vasopressin, and insulin was abolished by removing extracellular Na+. The inhibition was reversible, time- and Na+-concentration-dependent, and not due to an effect on binding or internalization of 125I-EGF. Stimulation by combinations of other growth factors with different mechanis...

previous studies had shown that sub-inhibitory concentrations of silver sulphadiazine (agsd) stimulated the production of toxic shock syndrome toxin-1 in certain strains (responder strains) of staphylococcus aureus and that protease production was also affected. no changes were detected in other strains (non-responders). extracellular proteins from eleven responder and non-responder strains gro...
