چکیده
Insulin/Insulin-like growth factors play important roles in promoting proliferation, differentiation, growth and development of organisms. In this article, bioinformatics analysis was performed to locate and identify the Bombyx mori insulin-like peptide (BmILP) gene, which had two introns, three exons, and a predicted signal peptide at the front, and it also determined that BmILP was the same to the gene Bombyxin Z1, a member of the bombyxin family. Both the full-length BmILP gene and the gene without the signal peptide expressed mainly existed in inclusion body forms at different induction conditions and it was noted that the signal peptide had significant influence on the expression level. In addition, protein-protein interaction experiments suggested that there was interaction between BmILP and the autophagy-related protein Atg8, indicating that BmILP may play a role in immunity. It was found was that BmILP predominantly produced by the ovary among different tissues in the silkworm. Particularly, the adult females had higher expression levels than the adult males, and the expression level appeared to be the highest in the mated female moths, suggesting that BmILP may be a key factor in the regulation of egg maturation in Bombyx mori.

The immune and neuroendocrine systems of invertebrates, as well as vertebrates, share a common pool of molecules that have been conserved throughout evolution. Now we add a new interface to this bidirectional interaction, demonstrating the involvement of the gut system, showing that these three systems use the same biologically active peptides.
متن کاملComparison of the effectiveness of ISJ and SSR markers and detection of outlier loci in conservation genetics of Pulsatilla patens populations
BACKGROUND Research into the protection of rare and endangered plant species involves genetic analyses to determine their genetic variation and genetic structure. Various categories of genetic markers are used for this purpose. Microsatellites, also known as simple sequence repeats (SSR), are the most popular category of markers in population genetics research. In most cases, microsatellites ac...
متن کاملFingerprinting of some Egyptian rice genotypes using Intron-exon Splice Junctions (ISJ) markers
DNA fingerprinting has become an important tool for diversity assessment and varietal identification in plant breeding programs. Semi- random PCR primers targeting intron-exon splice junctions (ISJ) were used to evaluate the potential of these markers in identification and classification of rice genotypes. A total of 12 ISJ primers were used for screening fourteen Egyptian rice genotypes, inclu...
متن کاملInhibition of protein kinase C by isojacareubin suppresses hepatocellular carcinoma metastasis and induces apoptosis in vitro and in vivo
Targeted inhibition of protein kinase C (PKC) inhibits hepatocellular carcinoma (HCC) proliferation and metastasis. We previously reported the cytotoxicity of a series of synthetic phenyl-substituted polyoxygenated xanthone derivatives against human HCC. In the current study, the most potent natural product, isojacareubin (ISJ), was synthesized, and its cellular-level antihepatoma activities we...
