Cytogenetic and protein quantification in polyploid somatic tissue of Myrmeleon uniformis (Neuroptera, Myrmeleontidae)

C. A. Pacheco, da Silva, T. L., and Kobayashi, M. K. H., Cytogenetic and protein quantification in polyploid somatic tissue of Myrmeleon uniformis (Neuroptera, Myrmeleontidae), vol. 14, pp. 3877-3878, 2015.

Myrmeleon unifomis Malpighian tubules cells were analyzed under two aspects: chro­matin structure and total protein quantification in the three larval phases (L1, L2 and L3) and in adults. This insect Malpighian tubules present polyploid tissue resultant from endoreduplica­tion, which probably begins in the first larval phases.

Methylation status and chromatin structure of the myostatin gene promoter region in the sea perch Lateolabrax japonicus (Perciformes)

E. M. Abbas, Takayanagi, A., Shimizu, N., and Kato, M., Methylation status and chromatin structure of the myostatin gene promoter region in the sea perch Lateolabrax japonicus (Perciformes), vol. 10, pp. 3306-3315, 2011.

Myostatin is a negative regulator of the growth and development of skeletal muscle mass. In fish, myostatin is expressed in several organs in addition to skeletal muscle. To understand the mechanisms regulating myostatin gene expression in the sea perch, Lateolabrax japonicus, we examined the methylation status of the myostatin gene promoter region in several tissues (liver, eye, kidney, brain, and heart) isolated from adult specimens.
