Increased transcription of a major stress gene in spontaneously hypertensive miceP Hamet
Clinical Research Institute of Montreal, Quebec, Canada
Hypertension 15:904-8. 1990..The present studies demonstrate that increased hsp70 gene expression is due to its heightened transcription rate. The genetic basis of environmental susceptibility to hypertension may thus involve an abnormal control of heat shock genes...
HCO3-dependent impact of Na+,K+,2Cl- cotransport in vascular smooth muscle excitation-contraction couplingSvetlana V Koltsova
