The role of statins in lung cancer

open access: yesArchives of Medical Science, 2021
Lung cancer is one of the most common causes of cancer-related mortality in the 21st century. Statins as inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase not only reduce the cholesterol levels in the blood and decrease the risk of ...

The Role of Mg2+ Cofactor in the Guanine Nucleotide Exchange and GTP Hydrolysis Reactions of Rho Family GTP-binding Proteins*

open access: yesJournal of Biological Chemistry, 2000
The biological activities of Rho family GTPases are controlled by their guanine nucleotide binding states in cells. Here we have investigated the role of Mg2+ cofactor in the guanine nucleotide binding and hydrolysis processes of the Rho family members ...

Involvement of the GTP binding protein Rho in constitutive endocytosis in Xenopus laevis oocytes. [PDF]

open access: yesThe Journal of cell biology, 1995
To study an endocytotic role of the GTP-binding protein RhoA in Xenopus oocytes, we have monitored changes in the surface expression of sodium pumps, the surface area of the oocyte and the uptake of the fluid-phase marker inulin. Xenopus oocytes possess intracellular sodium pumps that are continuously exchanged for surface sodium pumps by constitutive ...

Sensor potency of the moonlighting enzyme-decorated cytoskeleton [PDF]

open access: yes, 2013
Background: There is extensive evidence for the interaction of metabolic enzymes with the eukaryotic cytoskeleton. The significance of these interactions is far from clear.

Cdc42/Rac Interactive Binding Containing Effector Proteins in Unicellular Protozoans With Reference to Human Host: Locks of the Rho Signaling

open access: yesFrontiers in Genetics, 2022
Small GTPases are the key to actin cytoskeleton signaling, which opens the lock of effector proteins to forward the signal downstream in several cellular pathways. Actin cytoskeleton assembly is associated with cell polarity, adhesion, movement and other

Bimodal expression of RHOH during myelomonocytic differentiation: Implications for the expansion of AML differentiation therapy

open access: yeseJHaem, 2021
RhoH is an unusual member of the Rho family of small GTP‐binding proteins in that it lacks GTPase activity. Since the RhoH protein is constantly bound by GTP, it is constitutively active and controlled predominantly by changes in quantitative expression.

Vav family exchange factors: Potential regulator in atherosclerosis

open access: yesBiochemistry and Biophysics Reports
The Vav family of guanosine nucleotide exchange factors (GEFs) regulates the phosphorylation of tyrosinase, influencing various physiological and pathological processes by modulating the binding of Rho GTPases to GDP/GTP.

Secretopathies emerge as a new class of neurocristopathies

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Neural crest cells are a transient embryonic population of cells that give rise to a wide range of structures, including craniofacial cartilage and bone, peripheral neurons and glia, as well as components of the cardiac outflow tract, among others.

Baicalein Sensitizes Radioresistant BT549 and MCF7‐R Breast Cancer Cells by Modulating Rac1 Signaling

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Radioresistance remains a key barrier in breast cancer (BC) treatment. Baicalein, a flavonoid from Scutellaria baicalensis, has shown potential to enhance radiosensitivity. This study investigates its efficacy and mechanism in radioresistant BC models. Radioresistant BC cell models were established via fractionated irradiation and validated by
