Mechanical Cues Regulate Cargo Sorting and Export at the Golgi

open access: yesAdvanced 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.

Phase II evaluation of VDC-1101 in canine cutaneous T-cell lymphoma. [PDF]

open access: yes, 2014
BackgroundCanine cutaneous T-cell lymphoma (CTCL) is an uncommon disease for which efficacious therapies are lacking. The novel anticancer nucleotide prodrug VDC-1101 (formerly known as GS-9219) has shown efficacy in dogs with multicentric lymphoma.

eIF4E Enriched Extracellular Vesicles Induce Immunosuppressive Macrophages through HMGCR‐Mediated Metabolic Rewiring

open access: yesAdvanced Science, EarlyView.
Here, it is revealed that ovarian cancer cells release extracellular vesicles enriched with eIF4E, which alters protein production in macrophages. This leads to increased expression of 3‐hydroxy‐3‐methyl‐glutaryl‐coenzyme A reductase (HMGCR), boosting cholesterol synthesis and activating an immunosuppressive pathway through X‐box binding protein 1 and ...

Homologous and unique G protein alpha subunits in the nematode Caenorhabditis elegans [PDF]

open access: yes, 1991
A cDNA corresponding to a known G protein alpha subunit, the alpha subunit of Go (Go alpha), was isolated and sequenced. The predicted amino acid sequence of C. elegans Go alpha is 80-87% identical to other Go alpha sequences.

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

open access: yesAdvanced 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.

Hydration of a B-DNA Fragment in the Method of Atom-atom Correlation Functions with the Reference Interaction Site Model Approximation

open access: yes, 1998
We propose an efficient numerical algorithm for solving integral equations of the theory of liquids in the Reference Interaction Site Model (RISM) approximation for infinitely dilute solution of macromolecules with a large number of atoms.

7‐Ketodeoxycholic Acid Promotes Colonic Mucosal Healing by Inducing Calcium Release from Endoplasmic Reticulum via the TGR5‐IP3R Pathway

open access: yesAdvanced Science, EarlyView.
7‐KDCA functions by driving intestinal epithelial cell migration through induction of calcium release from the endoplasmic reticulum. The findings emphasize a previously unrecognized property of 7‐KDCA in regulating cell migration, a required process for effective epithelial restitution and repair that is particularly critical for patients with UC to ...

Design and Properties of Ligand-Conjugated Guanine Oligonucleotides for Recovery of Mutated G-Quadruplexes

open access: yesMolecules, 2018
The formation of a guanine quadruplex DNA structure (G4) is known to repress the expression of certain cancer-related genes. Consequently, a mutated G4 sequence can affect quadruplex formation and induce cancer progression. In this study, we developed an

Xylose Metabolism Perturbation in Yarrowia lipolytica for Efficient Succinic Acid Bioproduction from Lignocellulosic Biomass

open access: yesAdvanced Science, EarlyView.
This study engineers Yarrowia lipolytica to produce succinic acid (SA) from lignocellulosic biomass. Adaptive evolution and multi‐omics analysis identify regulators that alleviate xylose metabolic disorder. Multi‐copy integration of xylose metabolic genes resolves redox imbalances from a futile fatty acid cycle, producing high‐titer SA from corn stover

Intermediate filaments spatially organize intracellular nanostructures to produce the bright structural blue of ribbontail stingrays across ontogeny

open access: yesFrontiers in Cell and Developmental Biology
In animals, pigments but also nanostructures determine skin coloration, and many shades are produced by combining both mechanisms. Recently, we discovered a new mechanism for blue coloration in the ribbontail stingray Taeniura lymma, a species with ...
