The autophagy-related gene in regulates both neuron and midgut homeostasis.

is an autophagy-related gene identified in worms, flies, mice, and mammals, which encodes a protein that functions in autophagosome formation by associating with the ULK1-Atg13-Fip200 complex. In the last few years, the critical role of Atg101 in autophagy has been well-established through biochemical studies and the determination of its protein structure. However, Atg101's physiological role, both during development and in adulthood, remains less understood.

Hcf regulates the Hippo signaling pathway via association with the histone H3K4 methyltransferase Trr.

Control of organ size is a fundamental aspect in biology and plays important roles in development. The Hippo pathway is a conserved signaling cascade that controls tissue and organ size through the regulation of cell proliferation and apoptosis. Here, we report on the roles of Hcf (host cell factor), the homolog of Host cell factor 1, in regulating the Hippo signaling pathway.

A positive role of Sin3A in regulating Notch signaling during Drosophila wing development.

Notch is a transmembrane receptor that mediates intercellular signaling through a conserved signaling cascade in all animal species. Transcriptional and posttranscriptional regulation of Notch receptor are important for maintaining Notch signaling activity. Here, we show that depletion of Drosophila Sin3A leads to loss of the adult wing margin and downregulation of Notch target gene expression in the developing wing disc.

The histone deacetylase HDAC1 positively regulates Notch signaling during wing development.

The Notch signaling pathway is highly conserved across different animal species and plays crucial roles in development and physiology. Regulation of Notch signaling occurs at multiple levels in different tissues and cell types. Here, we show that the histone deacetylase HDAC1 acts as a positive regulator of Notch signaling during wing development.
