Coronary Microvascular Dysfunction: Epidemiology, Pathophysiology, Diagnosis, and Treatment

open access: yesMedComm, Volume 7, Issue 8, August 2026.
This visual summary illustrates the key aspects of coronary microvascular dysfunction (CMD) in angina with nonobstructive coronary artery disease (NOCAD), including epidemiology, pathophysiology (microvascular remodeling and endothelial dysfunction), the protective NRG‐1/ErbB signaling pathway, diagnostic methods, and both Western and traditional ...

Cell wall stress depolarizes cell growth via hyperactivation of RHO1 [PDF]

open access: yes, 1999
Cells sense and physiologically respond to environmental stress via signaling pathways. Saccharomyces cerevisiae cells respond to cell wall stress by transiently depolarizing the actin cytoskeleton.

rho, a Small GTP-Binding Protein, Is Essential for Shigella Invasion of Epithelial Cells [PDF]

open access: yesThe Journal of Experimental Medicine, 1997
Shigella, the causative agents of bacillary dysentery, are capable of invading mammalian cells that are not normally phagocytic. Uptake of bacteria by the mammalian cells is directed by bacterial factors named IpaB, IpaC, and IpaD invasins, in which Ipa invasins secreted into the bacterial environment can interact with α5β1 integrin.

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

open access: yesFEBS Open Bio, Volume 16, Issue 7, Page 1414-1427, July 2026.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

Ect2/Pbl Acts via Rho and Polarity Proteins to Direct the Assembly of an Isotropic Actomyosin Cortex upon Mitotic Entry. [PDF]

open access: yes, 2015
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.

Role of Phospholipase D in G-Protein Coupled Receptor Function

open access: yesMembranes, 2014
Prolonged agonist exposure of many G-protein coupled receptors induces a rapid receptor phosphorylation and uncoupling from G-proteins. Resensitization of these desensitized receptors requires endocytosis and subsequent dephosphorylation.

Natural Biomaterials for Osteochondral Repair: From Source to Strategy

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 27, 17 July 2026.
Biological origin‐guided overview of natural biomaterials and therapeutic strategies for osteochondral tissue engineering. The circular diagram categorizes representative materials and strategies into plant/algae‐derived, microbial‐derived, animal‐derived, and human‐derived sources, centered on an osteochondral defect repair model.

Characterization of the RhoGAP proteins RGA-3 and RGA-4 and the centrosomal protein SAS-5 in the early "Caenorhabditis elegans" embryo [PDF]

open access: yes, 2007
The Caenorhabditis elegans embryo serves as a great tool to study cell biological processes like polarization and cell divison. The first cell division is unequal and cell polarization is dependant on the Rho GTPase regulated rearrangement of the cell ...

Unraveling the Molecular Mechanisms Underlying Spontaneous Multipolar Mitosis Through CIN‐seq

open access: yesAdvanced Science, Volume 13, Issue 40, 17 July 2026.
Multipolar mitosis, a hallmark of chromosomal instability (CIN), drives tumor heterogeneity but is challenging to study in live cells. Using CIN‐seq, a single‐cell multiomics method, we profiled rare CIN events and identified mechanisms associated with viable multipolar mitosis, including PTEN attenuation, Rho GTPase‐driven cytokinesis failure, and ...

Annexin 11 is required for midbody formation and completion of the terminal phase of cytokinesis [PDF]

open access: yes, 2004
Annexins are Ca(2+)-binding, membrane-fusogenic proteins with diverse but poorly understood functions. Here, we show that during cell cycle progression annexin 11 translocates from the nucleus to the spindle poles in metaphase and to the spindle midzone ...
