Phosphatidylserine polarization is required for proper Cdc42 localization and for development of cell polarity. [PDF]
We used genetically-encoded fluorescent probes to visualize the distribution of phosphatidylserine (PS) in live S. cerevisiae. The majority of the PS was found to reside in the cytosolic leaflet of the plasma membrane.

Ect2/Pbl Acts via Rho and Polarity Proteins to Direct the Assembly of an Isotropic Actomyosin Cortex upon Mitotic Entry. [PDF]
Entry into mitosis is accompanied by profound changes in cortical actomyosin organization. Here, we delineate a pathway downstream of the RhoGEF Pbl/Ect2 that directs this process in a model epithelium.

Comparison of extracellular vesicles with parental cells through proteomic profiling, followed by an integrated bioinformatic pipeline including disease association and transcriptomic analyses, identifies candidate biomarkers for multiple myeloma. Among these, MIF emerges as a clinically relevant marker, supported by validation in patient samples and ...

The pH dependence of polymerization and bundling by the essential bacterial cytoskeltal protein FtsZ [PDF]
There is a growing body of evidence that bacterial cell division is an intricate coordinated process of comparable complexity to that seen in eukaryotic cells.

Genome-Wide Analysis of Gene and Protein Expression of Dysplastic Naevus Cells
Cutaneous melanoma, a type of skin tumor originating from melanocytes, often develops from premalignant naevoid lesions via a gradual transformation process driven by an accumulation of (epi)genetic lesions.

Regulation of vacuolar H+-ATPase activity by the Cdc42 effector Ste20 in Saccharomyces cerevisiae [PDF]
In the budding yeast Saccharomyces cerevisiae, the Cdc42 effector Ste20 plays a crucial role in the regulation of filamentous growth, a response to nutrient limitation.

The primary function of statins is to inhibit cholesterol synthesis, which contributes to their antidiabetic effects. However, the majority of the diabetic effects of statins are due to inhibition of isoprenoid synthesis. Atorvastatin, simvastatin and rosuvastatin possess the most pronounced diabetogenic properties. In contrast, lovastatin, fluvastatin,

Functional Specialization of Clathrin‐Independent Endocytic Routes: Mechanisms and Cellular Roles
Distinct clathrin‐independent endocytic (CIE) routes support specialized cellular functions across different contexts. Created with Biorender.com. ABSTRACT Clathrin‐independent endocytosis (CIE) comprises a diverse repertoire of internalization mechanisms that operate in parallel with clathrin‐mediated endocytosis.

Guanosine nucleotides regulate B2 kinin receptor affinity of agonists but not of antagonists: Discussion of a model proposing receptor precoupling to G protein [PDF]
The effect of nucleotides on binding of the B2 kinin (BK) receptor agonist {[}H-3]BK and the antagonist {[}H-3]NPC17731 to particulate fractions of human foreskin fibroblasts was studied.
