The study of the insulin-like peptides of Drosophila can provide insight of their similarities to mammalian insulin and their potential usage in treating human insulin-related diseases. In this study, we isolated and characterized cDNA encoding insulin-like peptide (ILP) 5 in D. virilis by using RNA purification, reverse transcription, and RACE protocols. Subsequently, various bioinformatic softwares were employed to predict peptide structure. The ILP5 gene (587 base pairs) codes for 121 amino acids that make up prepro-ILP5. After maturation, functional ILP5 is a peptide of two 25 amino acid chains, A- and B-chain, connected by two disulfide bonds. Sequencing genomic DNA …

Alzheimer’s disease is a degenerative neurological illness characterized by the deterioration of brain regions implicated in memory and cognitive function. While researchers have yet to find a cure or effective treatment, they have gained a better understanding of its pathology and development. Through years of neuroscience research, scientists have discovered much of what happens in the brain during Alzheimer’s disease onset and how this causes its symptoms; many hypotheses regarding this aspect of the illness involve temporal lobe atrophy, neurofibrillary tangles, and amyloid plaques. Although Alzheimer’s disease affects millions of people every day, it seems that most are unaware of …
