Article Abstract

The need to coordinate patterning and growth has been appreciated for many years. The logic that enables seamless integration of the relevant inputs is beginning to be elucidated, particularly in wing imaginal discs of Drosophila. In this tissue, multiple regulatory layers involving the two morphogens Wingless and Dpp, the wing-specific determinant, Vestigial, and the Hippo pathway, converge to regulate growth. Intricate cross-regulation between these components may explain why, at the local level, there is no direct correlation between growth and the graded signalling activity of Wingless and Dpp, despite the requirement of these two pathways for growth.

A fundamental focus of evolutionary-developmental biology is uncovering the genetic mechanisms responsible for the gain and loss of characters. One approach to this question is to investigate changes in the coordinated expression of a group of genes important for the development of a character of interest (a gene regulatory network). Here we consider the possibility that modifications to the wing gene regulatory network (wGRN), as defined by work primarily done in , were involved in the evolution of wing dimorphisms of the pea aphid ().

Spongy moth, Lymantria dispar Linnaeus (Lepidoptera: Erebidae), stands as a pervasive international threat, marked by its designation as one of the "world's 100 worst invasive species" by IUCN, owing to its voracious leaf-eating habits encompassing over 500 plant species. Its strong flight ability facilitates its spread and invasion. The present study aims to uncover differential gene expression, utilizing the Illumina Novaseq6000 sequencing platform for comprehensive transcriptome sequencing and bioinformatic analysis of total RNA extracted from larvae and pupae.

During development, unique combinations of transcription factors and signaling pathways carve the nascent eye-antennal disc of the fruit fly Drosophila melanogaster into several territories that will eventually develop into the compound eye, ocelli, head epidermis, bristles, antenna and maxillary palpus of the adult head. Juxtaposed patterns of Hedgehog (Hh) and Decapentaplegic (Dpp) initiate compound eye development, while reciprocal domains of Dpp and Wingless (Wg) induce formation of the antennal and maxillary palp fields. Hh and Wg signaling, but not Dpp, contribute to the patterning of the dorsal head vertex.

Article Synopsis
  • This study explores DNA methylation and gene expression in blood cells from systemic sclerosis (SSc) patients, particularly those with interstitial lung disease (ILD), to understand how these factors influence Wnt/β-catenin and chemokine signaling pathways.
  • Blood samples were taken from 19 SSc patients (including a subgroup with ILD) and 18 healthy controls, with techniques used to measure DNA methylation and gene expression.
  • Findings revealed significant differences in DNA methylation and gene expression between the SSc with ILD and SSc without ILD groups, highlighting specific genes and signaling pathways that may be impacted by methylation in autoimmune responses.

Morphogens provide quantitative and robust signaling systems to achieve stereotypic patterning and morphogenesis. Heparan sulfate (HS) proteoglycans (HSPGs) are key components of such regulatory feedback networks. In Drosophila, HSPGs serve as co-receptors for a number of morphogens, including Hedgehog (Hh), Wingless (Wg), Decapentaplegic (Dpp) and Unpaired (Upd, or Upd1).
