Mechanical Cues Regulate Cargo Sorting and Export at the Golgi

Advanced Science, EarlyView.
A pathway is identified linking extracellular matrix stiffness to secretion via Src–FAK–AMPK–GBF1 signaling. Golgi‐localized GBF1 acts as a mechanotransducer whose phosphorylation controls post‐Golgi cargo sorting toward secretion or lysosomal degradation.

Tubulins in C. elegans [PDF]

, 2018
The C. elegans tubulin family is composed of nine α-, six β-, and one γ-tubulin. Tubulins are highly conserved, functioning as α-β heterodimers that assemble into microtubules.

Adenylosuccinate Synthase 1 Deficiency Improves Energy Metabolism by Promoting Adipose Tissue Re‐esterification via Glycerol Kinase Upregulation

Advanced Science, EarlyView.
Working model of Adss1‐mediated regulation of energy metabolism in adipose tissue. In beige adipocytes, Adss1 interacts with HDAC3 in the cytoplasm, and its loss reduces nuclear HDAC3 while increasing cytosolic fractions. This redistribution suppresses HDAC activity and enhances H3K27 acetylation at the Gk promoter, leading to transcriptional ...

RAB family gene expression in breast cancer cells under influence of paclitaxel [PDF]

, 2011
The aim of this study was to investigate the role of paclitaxel on RAB family of genes in primary breast cancer cell lines. The cancer breast cells obtained from 40 women during mastectomy were used to address this issue. The group included patients with

Chlamydia Hijacks ARF GTPases To Coordinate Microtubule Posttranslational Modifications and Golgi Complex Positioning. [PDF]

, 2017
The intracellular bacterium Chlamydia trachomatis develops in a parasitic compartment called the inclusion. Posttranslationally modified microtubules encase the inclusion, controlling the positioning of Golgi complex fragments around the inclusion.

Gigaxonin Potentiates Antiviral Innate Immune Responses by Targeting cGAS and TREX1

Advanced Science, EarlyView.
TREX1 antagonizes DNA sensor cGAS by degrading cytosolic DNA. This work identifies gigaxonin as a molecular switch that coordinates DNA sensing and clearance pathways to amplify antiviral responses. Under the steady state, gigaxonin maintains cellular homeostasis by mediating TREX1 ubiquitination and proteasomal degradation. During DNA virus infection,

The long noncoding RNA CARDINAL attenuates cardiac hypertrophy by modulating protein translation

The Journal of Clinical Investigation
One of the features of pathological cardiac hypertrophy is enhanced translation and protein synthesis. Translational inhibition has been shown to be an effective means of treating cardiac hypertrophy, although system-wide side effects are common ...

Molecular mechanism of Gαi activation by non-GPCR proteins with a Gα-Binding and Activating motif [PDF]

, 2017
Heterotrimeric G proteins are quintessential signalling switches activated by nucleotide exchange on Gα. Although activation is predominantly carried out by G-protein-coupled receptors (GPCRs), non-receptor guanine-nucleotide exchange factors (GEFs) have

Novel Evolutionarily Conserved Oncogene COA4 is Driven by KRAS Mutant and Promotes Cancer Metastasis Through Dual Mitochondrial Metabolism‐Dependent and ‐Independent Mechanisms

Advanced Science, EarlyView.
In KRAS‐mutant tumors, KRAS transcriptionally upregulates COA4 via the PI3K/AKT/E2F1 axis, promoting metastasis. Mechanistically, COA4 enhances tumor cell migration through dual pathways: within mitochondria, it boosts oxidative phosphorylation; in the cytoplasm, it binds and activates CDC42 to stimulate pseudopodia formation.
