From lymphocytes to sharks: V(D)J recombinase moves to the germline.

The antigen-receptor genes of vertebrates are rearranged by a specialized somatic recombination mechanism in developing lymphocytes - and, unexpectedly, also in the germline of cartilaginous fishes. The recombination system that carries out these DNA rearrangements may thus be a significant evolutionary force, perhaps not limited to rearrangements at antigen-receptor loci.

Improvement of shark type I collagen with microbial transglutaminase in urea.

In the presence of urea, type I collagen could form a gel with crosslinks with microbial transglutaminase (MTGase). Collagen self-assembly was accelerated with the addition of MTGase. The proportion of reconstructed collagen fibrils was raised with the addition of MTGase. MTGase-treated collagen gel remained gelled at high temperatures at which collagen denatured. By treatment with MTGase, collagen could form the gel under impossible condition to collagen self-assembly, and that denaturation temperature was raised.
