FlyVar is a publicly and freely available platform that addresses the increasing need of next generation sequencing data analysis in the Drosophila research community. It is composed of three parts. First, a database that contains 5.94 million DNA polymorphisms found in Drosophila melanogaster derived from whole genome shotgun sequencing of 612 genomes of D. melanogaster. In addition, a list of 1094 dispensable genes has been identified. Second, a graphical user interface (GUI) has been implemented to allow easy and flexible queries of the database. Third, a set of interactive online tools enables filtering and annotation of genomic sequences obtained from individual D. melanogaster strains to identify candidate mutations. FlyVar permits the analysis of next generation sequencing data without the need of extensive computational training or resources. Database URL: www.iipl.fudan.edu.cn/FlyVar.

Balanced self-renewal and differentiation of stem cells are crucial for maintaining tissue homeostasis, but the underlying mechanisms of this process remain poorly understood. Here, from an RNA interference (RNAi) screen in adult Drosophila intestinal stem cells (ISCs), we identify a factor, Pax, which is orthologous to mammalian PXN, coordinates the proliferation and differentiation of ISCs during both normal homeostasis and injury-induced midgut regeneration in Drosophila. Loss of Pax promotes ISC proliferation while suppressing its differentiation into absorptive enterocytes (ECs).

The current investigation intended to assess the controlled delivery of 7-sulfonamide-2-(4-methylphenyl) imidazo[2,1-b] [1, 3] benzothiazole an anticancer agent (ACA) by tamarind seed gum-based hydrogel; for its potential activity against hepatocellular carcinoma. The FTIR spectra, SEM, C NMR, PXRD, and TGA analyses evidenced the successful loading of ACA into the hydrogel system. The rheological testing conveyed the increase in the elastic nature of ACA-loaded hydrogel helping in an effective release.

Non-nutritive sweeteners (NNSs) are used to reduce caloric intake by replacing sugar with compounds that are sweet but contain little or no calories. In this study, we investigate how non-nutritive sweetener sucralose to promote acute food intake in the fruit fly Drosophila melanogaster. Our results showed that acute exposure to NNSs sweetness induces a robust hyperphagic response in flies.

Norepinephrine in vertebrates and its invertebrate analog, octopamine, regulate the activity of neural circuits. We find that, when hungry, larvae switch activity in type II octopaminergic motor neurons (MNs) to high-frequency bursts, which coincide with locomotion-driving bursts in type I glutamatergic MNs that converge on the same muscles. Optical quantal analysis across hundreds of synapses simultaneously reveals that octopamine potentiates glutamate release by tonic type Ib MNs, but not phasic type Is MNs, and occurs via the G-coupled octopamine receptor (OAMB).

Dorsal closure is a process that occurs during embryogenesis of . During dorsal closure, the amnioserosa (AS), a one-cell thick epithelial tissue that fills the dorsal opening, shrinks as the lateral epidermis sheets converge and eventually merge. During this process, both shape index and aspect ratio of amnioserosa cells increase markedly.
