Studies on a nonpolysomal ribonucleoprotein coding for myosin heavy chains from chick embryonic muscles.
A messenger ribonucleoprotein (mRNP) particle containing the mRNA coding for the myosin heavy chain (MHC mRNA) has been isolated from the postpolysomal fraction of homogenates of 14-day-old chick embryonic muscles. The mRNP sediments in sucrose gradient as 120 S and has a characteristic buoyant density of 1.415 g/cm3, which corresponds to an RNA:protein ratio of 1:3.8. The RNA isolated from the...
متن کاملMyosin isozymes in normal and cross-reinnervated cat skeletal muscle fibers
Immunocytochemical characteristics of myosin have been demonstrated directly in normal and cross-reinnervated skeletal muscle fibers whose physiological properties have been defined. Fibers belonging to individual motor units were identified by the glycogen-depletion method, which permits correlation of cytochemical and physiological data on the same fibers. The normal flexor digitorum longus (...
متن کاملCharacterization of myosin heavy chains from the mantle muscles of cephalopods
Myosin heavy chain (MyHC) genes from the mantle muscles of three cephalopod species, namely, golden cuttlefish Sepia esculenta, Japanese common squid Todarodes pacificus, and spear squid Loligo bleekeri were subjected to synthesis of first strand cDNA by reverse transcription-PCR. As a result of sequencing of the obtained cDNA fragments, the MyHCs from S. esculenta and L. bleekeri were found to...
متن کاملImmunohistochemical analysis of myosin heavy chain expression in laryngeal muscles of the rabbit, cat, and baboon.
We studied myosin heavy chain (MyHC) expression and fiber type distribution in laryngeal muscles in the rabbit, cat, and baboon using immunohistochemistry with highly MyHC-specific antibodies. Two types of variation in MyHC expression were found: between muscles of different function within species and within specific muscles between species. Within species, thyroarytenoid (Ta), an adductor, ha...
متن کاملThe content of myosin heavy chains in hindlimb muscles of female and male rats.
The aim of the study was to test whether the considerable differences in the hindlimb muscles mass, the number and diameter of muscles fibers were connected with differences in the myosin heavy chain isoform content (expressed as the percentage of the given isoform in respect to total myosin heavy chains). Therefore, the content of myosin heavy chain (MHC) isoforms was studied in four hindlimb ...
