Discovery of an Atypical Arp2/3 Complex in Malaria Parasites Sheds New Light on Nuclear Actin

Cytoskeleton, EarlyView.
ABSTRACT The Arp2/3 complex is a key actin nucleator essential for cytoskeletal dynamics in eukaryotes. Previously believed absent in apicomplexan parasites, we recently identified an atypical Arp2/3 complex in malaria parasites consisting of five divergent subunits and a putative kinetochore‐associated factor.

A high-throughput screen identifies that CDK7 activates glucose consumption in lung cancer cells. [PDF]

, 2019
Elevated glucose consumption is fundamental to cancer, but selectively targeting this pathway is challenging. We develop a high-throughput assay for measuring glucose consumption and use it to screen non-small-cell lung cancer cell lines against ...

Isoform Specificity of a Compound Targeting Actin Filaments Containing Tropomyosin Tpm1.8/1.9

Cytoskeleton, EarlyView.
ABSTRACT The unbranched actin filaments in mammalian cells are usually composed of co‐polymers of a specific tropomyosin isoform with actin. Genetic manipulation has revealed that the tropomyosins largely define the functional properties of actin filaments in an isoform‐specific, non‐redundant manner.

Berberine bridge enzyme-like oxidase-catalysed double bond isomerization acts as the pathway switch in cytochalasin synthesis

Nature Communications, 2022
Cytochalasans are a large family of fungal polyketide-nonribosomal peptide hybrid natural products that exhibit important pharmaceutical activities, but the mechanism of conversion of the monocytochalasans to the polycyclic, fused analogues is unclear ...

Compartmentalisation and localisation of the translation initiation factor (eIF) 4F complex in normally growing fibroblasts [PDF]

, 2006
Previous observations of association of mRNAs and ribosomes with subcellular structures highlight the importance of localised translation. However, little is known regarding associations between eukaryotic translation initiation factors and cellular ...

Mitochondria and the Actin Cytoskeleton in Neurodegeneration

Cytoskeleton, EarlyView.
ABSTRACT Mitochondrial dysfunction and cytoskeletal disorganization are widely recognized hallmarks of neurodegenerative diseases such as Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), and amyotrophic lateral sclerosis (ALS).

PHYTOTOXIC CONSTITUENTS FROM ENDOPHYTIC FUNGUS Xylaria cubensis ASSOCIATED WITH Eugenia brasiliensis

Química Nova
The upscaling of Xylaria cubensis, an endophyte of Eugenia brasiliensis (Myrtaceae), in PDB medium led to the isolation of known compounds including cytochalasin D (7) and cytochalasin C (8), which exhibited relatively higher phytotoxic activity in all ...

Regulation of elastase and plasminogen activator secretion in resident and inflammatory macrophages by receptors for the Fc domain of immunoglobulin G. [PDF]

, 1984
We have determined that the interaction of IgG-coated erythrocytes (EIgG) and complement-coated erythrocytes (EIgMC) with macrophage Fc and complement receptors, respectively, modulates the secretion of the neutral proteinases, elastase, and plasminogen ...
