摘要: Hormones can be regarded as chemical mediators which, under the control of central nervous system (CNS), elicit responses in specific tissues necessary for homeostasis organism a whole. The last few years have witnessed an intensive search molecular mechanisms underlying physiological action hormones. Because complexity multicellular organism, hormonal occurring at cellular sites are far removed, both spatially and temporally, from site hormone synthesis release. Attempts to define primary biochemical locus therefore fraught with difficulties. Karlson(1) Zalokar(2) formulated concept that certain hormones involved functional differentiation capable modifying gene expression. This theory, which is inherent “operon” model Jacob Monod,(3) has had propelling influence on recent investigations into mode regulating protein biosynthesis; such studies providing valuable insights genetic regulatory synthesis.
