TPI1 Loss Triggers a Metabolite‐Driven Mitochondrial Redox Vulnerability via the SARM1–cADPR–Ca2+ Axis

Advanced Science, EarlyView.
Metabolite‐driven redox stress governs cancer cell senescence. TPI1 deficiency elevates DHAP, initiating SARM1‐dependent cADPR‐Ca2+ release. Mitochondrial ROS surge subsequently induces DNA damage and senescence, offering a conserved therapeutic target in multiple cancers.

Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila

Advanced Science, EarlyView.
While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.

SOX5 Orchestrates Malignant Evolution via Promoter‐Centric Chromatin Remodeling in MYC‐Driven B‐Cell Lymphoma

Advanced Science, EarlyView.
In MYC‐enforced B‐cell lymphoma, SOX5 occupies promoter‐proximal regulatory regions and is associated with reduced chromatin accessibility at the PCNP locus. PCNP repression promotes proliferative remodeling by limiting apoptosis and cell‐cycle restraint.

Phosphorylation of Pnut in the Early Stages of Drosophila Embryo Development Affects Association of the Septin Complex with the Membrane and Is Important for Viability

G3: Genes, Genomes, Genetics, 2018
Septin proteins are polymerizing GTPases that are found in most eukaryotic species. Septins are important for cytokinesis and participate in many processes involving spatial modifications of the cell cortex. In Drosophila, septin proteins Pnut, Sep1, and

Current Challenges of Transcription Compartmentalization Research

Advanced Science, EarlyView.
Transcription factors, coactivators, and RNA polymerase II assemble into transcription compartments ranging from small, defined complexes to liquid‐like condensates. This review unifies these seemingly competing descriptions along a single continuum and asks what these compartments have been shown to do, and what they have not, revealing that the most ...

Regulation of actin-Spectrin cytoskeleton by ICA69 at the Drosophila neuromuscular junction

Communicative & Integrative Biology, 2018
Bin-Amphiphysin-Rvs (BAR) domain containing proteins with their membrane deforming properties have emerged as key players in shaping up neuronal morphology and regulating cytoskeletal dynamics.

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia

Advanced Science, EarlyView.
Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

Untangling Inositol (Pyro)Phosphate Biology Through Emerging Technologies

Advanced Science, EarlyView.
Inositol (pyro)phosphates represent a vital class of intracellular messengers that govern multiple biological processes. The last decade has experienced a surge of interest in the functions of this class of signaling molecules, primarily due to the introduction of several innovative analytical technologies.

iProteinDB: An Integrative Database of Drosophila Post-translational Modifications

G3: Genes, Genomes, Genetics, 2019
Post-translational modification (PTM) serves as a regulatory mechanism for protein function, influencing their stability, interactions, activity and localization, and is critical in many signaling pathways.

Polarity proteins duel in Drosophila [PDF]

Journal of Cell Biology, 2014
![Figure][1] A control fly embryo (left) shows a normal cuticle, whereas the cuticle has fragmented in an embryo with a nonphosphorylatable version of Yurt (right). Gamblin et al. reveal how two proteins grapple to control polarity in epithelial cells.
