Pex30-dependent membrane contact sites maintain ER lipid homeostasis

In eukaryotic cells, communication between organelles and the coordination of their activities depend on membrane contact sites (MCS). How MCS are regulated under the dynamic cellular environment remains poorly understood. Here, we investigate how Pex30, a membrane protein localized to the endoplasmic reticulum (ER), regulates multiple MCS in budding yeast. We show that Pex30 is […]

Advances in Radiotherapy for Advanced Lung Cancer

In a groundbreaking meta-analysis published in BMC Cancer, researchers have shed new light on the evolving radiotherapy paradigms for treating locally advanced non-small cell lung cancer (LA-NSCLC), emphasizing innovations that could dramatically alter clinical outcomes. The study meticulously compares high-dose-rate (HDR) brachytherapy, stereotactic body radiotherapy (SBRT), and hypofractionated proton therapy—three cutting-edge modalities within the domain […]

Phosphatidic acid drives spatiotemporal distribution of Pex30 at ER-LD contact sites

Lipid droplets (LDs) are ubiquitous neutral lipid storage organelles that form at discrete subdomains in the ER bilayer. The assembly of these ER subdomains and the mechanism by which proteins are recruited to them is poorly understood. Here, we investigate the spatiotemporal distribution of Pex30 at the ER-LD membrane contact sites (MCSs). Pex30, an ER […]

Cargo adaptors use a handhold mechanism to engage with myosin V for organelle transport

Myo2, a class V myosin motor, is essential for organelle transport in budding yeast. Its association with cargo is regulated by adaptor proteins that mediate both attachment and release. Vac17, a vacuole-specific adaptor, links Myo2 to the vacuole membrane protein Vac8 and plays a key role in assembling and disassembling the Myo2–Vac17–Vac8 complex during vacuole […]

Broad-Spectrum Covalent Inhibitor Targets Coronavirus Mpro

In a groundbreaking leap forward for antiviral drug development, researchers have unveiled a novel covalent inhibitor that shows broad-spectrum efficacy against the main protease (M^pro) of human coronaviruses. This breakthrough illuminates a promising pathway toward universal antiviral therapies that could decisively curtail the threat posed by not only the current SARS-CoV-2 virus but also future […]

Anillin links up with RhoA to break the symmetry of cytokinetic ring closure

During animal cell cytokinesis, active RhoA assembles actomyosin-based contractile rings that tend to close asymmetrically. Through imaging C. elegans zygotes, Lebedev et al. (https://doi.org/10.1083/jcb.202405182) reveal that the scaffold protein, anillin, promotes asymmetric ring closure by locally sequestering RhoA from its canonical effectors and thereby limiting actomyosin contractility.

Crushing vs. Slashing: New skull scans reveal how giant dinosaurs killed

A new analysis of the bite strength of 18 species of carnivorous dinosaurs shows that while the Tyrannasaurus rex skull was optimized for quick, strong bites like a crocodile, other giant, predatory dinosaurs that walked on two legs — including spinosaurs and allosaurs — had much weaker bites and instead specialized in slashing and ripping […]
