Alterations in flight muscle ultrastructure and function in Drosophila tropomyosin mutants
Drosophila indirect flight muscle (IFM) contains two different types of tropomyosin: a standard 284-amino acid muscle tropomyosin, Ifm-TmI, encoded by the TmI gene, and two > 400 amino acid tropomyosins, TnH-33 and TnH-34, encoded by TmII. The two IFM-specific TnH isoforms are unique tropomyosins with a COOH-terminal extension of approximately 200 residues which is hydrophobic and rich in proli...
متن کاملLeukemogenesis: Small differences in Myb have large effects
The avian retroviruses E26 and AMV carry mutated versions of the gene encoding the cellular transcription factor c-Myb. Surprisingly, these two mutant forms of Myb differ in the subsets of myeloid cells that they transform, the target genes that they activate, and the way in which they are regulated.
متن کاملMyocyte-specific enhancer factor 2 acts cooperatively with a muscle activator region to regulate Drosophila tropomyosin gene muscle expression.
MEF2 (myocyte-specific enhancer factor 2) is a MADS box transcription factor that is thought to be a key regulator of myogenesis in vertebrates. Mutations in the Drosophila homologue of the mef2 gene indicate that it plays a key role in regulating myogenesis in Drosophila. We show here that the Drosophila tropomyosin I (TmI) gene is a target gene for mef2 regulation. The TmI gene contains a pro...
متن کاملThe Effects of Photobiomodulation on Shoulder Pain, Muscle Thickness, and Function in Subjects With Adhesive Capsulitis
Background: Adhesive capsulitis or frozen shoulder is among the most prevalent causes of pain and disability in individuals. Objectives: We aimed to evaluate the effect of Photobiomodulation (PBM) on pain, range of motion, and thickness and function of supraspinatus muscle in patients with adhesive capsulitis. Materials & Methods: Overall, 52 subjects (n=26/group) with adhesive capsulitis r...
متن کاملThe Differences in the Relaxant Effects of Different Fractions of Rosa damascena on Guinea Pig Tracheal Smooth Muscle
Objective(s) In the present study, the differences in the relaxant effects of aqueous, ethyl acetate and n-butanol fractions of Rosa damascena on tracheal smooth muscle of guinea pigs were examined. Materials and Methods The relaxant effects of three cumulative concentrations of each fraction (0.1, 0.2 and 0.4 g%) in comparison with saline and three cumulative concentrations of theophylline ...
