The titin immunoglobulin domain (TTID) protein localizes to the Z line in muscle and binds to alpha-actinin and gamma-filamin. It plays an indispensable role in stabilizing and anchoring of thin filaments. In this study, the 5'-regulatory region of the porcine TTID gene was analyzed with bioinformatic methods. Another objective of this study was to further investigate the polymorphism in the intron 6 of the porcine TTID gene. We determined allele frequency among six Chinese porcine purebreds.
Polymerase chain reaction-restriction fragment length polymorphism
The TaqI B polymorphism in the cholesterol ester transfer protein (CETP) (B1 and B2 alleles; rs708272) is associated with changes in enzyme activity and lipid concentrations. The B1 allele of the CETP gene is a known independent risk factor for genetic susceptibility to atrial fibrillation (AF); however, little is known about this polymorphism in the minority groups of Xinjiang, China.
Endangered angelsharks and a protected dolphin species are illegally traded in Brazil. In this study, we determined prospective molecular markers for detecting these species in the trade of angelshark carcasses and ‘dolphin’ eyeball amulets. We compiled publicly available as well as new and unpublished cytochrome b (cyt b) DNA sequences for species involved in these trades. These sequences were digested in silico using restriction enzymes.
Tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) is expressed in different tissues and cells, including the pancreas and lymphocytes, and it can selectively induce apoptosis in tumor cells but not in most normal cells. TRAIL plays critical roles in type 1 diabetes mellitus, and is involved in type 2 diabetes mellitus (T2DM).
