Cytokeratin expression in smooth muscle and smooth muscle tumours
Histopathology, 1987The expression of cytokeratin intermediate filaments by a tumour has been accepted as evidence of an epithelial origin. Although there have been anecdotal reports of Cytokeratin expression within tissues and neoplasms of non‐epithelial origin, particularly muscle, there have been no comprehensive studies of its frequency and distribution.

Cytokeratins in smooth muscle cells and smooth muscle tumours
Histopathology, 1988A keratin positive metastatic leiomyosarcoma in the lung, which resulted in diagnostic error, is reported. The results of additional studies of 17 benign and malignant leiomyogenic tumours with various keratin antibodies are presented and discussed in the light of recent bibliographical data.

Annual Review of Physiology, 1989
Muscle energetics now emcompasses several related areas. Historically, the approach of energetics was largely phenomenological and primarily involved quantitation of muscle heat production and mechanical output in order to define performance characteristics.

The greatest impetus to research in elucidating the fundamental biophysics and biochemistry of airway smooth muscle (ASM) has undoubtedly been provided by the need to understand how these are altered in asthma. Many of the biophysical and biochemical properties of this muscle have been reviewed before (Stephens, 1970; Stephens, 1977; Mulvaney, 1979 ...

Contraction of tracheal smooth muscle requires the binding of Ca2+ to calmodulin, which then binds to and activates MLCK. The Ca2+-calmodulin-MLCK complex catalyzes the phosphorylation of myosin, which causes contraction by stimulating actin-activated Mg2+-ATPase activity of myosin.
