Djsix-1 gene is one of the important eyespots-regulating genes in planarians. In this experiment, the expression of Djsix-1 and morphogenesis of eyespots during planarians eyespots regeneration were investigated. The planarians were subjected to two rounds of transverse amputation. Nineteen time points in the first round and ten ones in the second one(More)
Dugesia japonica has become the suitable model system for studying the visual system molecular developmental processes because of their simple structure and high regenerative capacity. To further dissect the molecular events of genetic network controlling the visual system regeneration in D. japonica, we investigated the morphogenesis of regenerating eyes(More)
Heat-shock protein 70 (HSP70) is ubiquitously found in a variety of organisms and plays an important role in cytoprotection, environmental monitoring, and disease resistance. In this study, the full-length complementary DNA (cDNA) of hsp70 from planarian Polycelis sp. was first cloned using rapid amplification of cDNA ends (RACE). The expression levels of(More)
Sox genes play important roles in animal developmental processes, including embryogenesis, neural cell stemness, neurogenesis, sex determination, among others. Here, the full length sox gene in planarian Dugesia japonica, named DjsoxB, was cloned using rapid amplification of cDNA ends (RACE). Phylogenetic analysis demonstrates that DjsoxB is highly(More)
Planarians provide the ideal model for studying eye development, with their simple eye structure and exceptionally rapid regeneration. Here, we observed the eye morphogenesis, photophobic behavior, spectral sensitivity and expression pattern of Djopsin in the freshwater planarian Dugesia japonica. The results showed that: (i) Djopsin encoding the putative(More)
The SPSB family is comprised of four highly conserved proteins, each containing a C-terminal SOCS box motif and a central SPRY domain. Presently, Spsb genes have been found in mammals and in a few invertebrates, however, the specific functions of these genes are still unknown. In this study, we identified a Spsb gene from the planarian Dugesia japonica and(More)
