Willoughby DS and Rosene J. Effects of oral creatine and resistance training
on myosin heavy chain expression.
Heart: Scientists of my generation didn't speak much about the heart unless, like me, they were working
on myosin structure or some such architectural piece.
Not exact matches
In their film, the researchers saw the
myosin crawl
on actin in contracting muscles.
«Actin can function as a track for
myosin, or as a motor
on its own via this comet tail mechanism.»
We have placed fluorescent labels
on portions of the tail regions of Arabidopsis
myosin XIs in order to determine whether they localize, and therefore what role a particular
myosin may play in movement of different types of organelles.
His recently published work defined the role of Rab11a and Rab8a interactions with
myosin Vb in the development of severe neonatal diarrhea in children with Microvillus Inclusion Disease and he has recently published work
on the phenotypes of mouse models of MYO5B KO.
«Future studies are focusing
on the molecular mechanisms underlying the ageing - related changes in skeletal muscle and the specific effects of HRT
on the structure and function of the dominant protein in skeletal muscle, called
myosin, which generates force and movement.»
The researchers found, however, that in mice these specialized training cells couldn't train
on the alpha -
myosin heavy chain protein because none of that protein was being produced in those cells.
These insights provide details about how
myosin motor proteins work, and this knowledge could advance the understanding of diseases related to movement
on a molecular level.
A final note
on the fate of amino acids - once absorbed, amino acids can be used directly by cells for the synthesis of new enzymes or new cell structures, for the building of structural proteins (such as actin and
myosin in the muscles), for the synthesis of OTHER amino acids (via transamination), or used for energy.
Engaging a muscle from its most optimal position and modulating the speed of contraction will result in the highest yield of actin -
myosin cross bridges for contractile purposes, being less dependent
on the mass of the object.
