Serotonin 5‐HT7 receptor signaling in neuropsychiatric disorders
5‐HT7R recruits Gs, G12, and β‐arrestin signaling to regulate neuronal plasticity, circuit function, and kinase‐linked intracellular responses. This review summarizes how these pathway‐selective modules contribute to autism spectrum disorder, depression, and schizophrenia, highlighting 5‐HT7R as a pathway‐informed therapeutic target. Abstract Serotonin

Vav1 inhibits RANKL-induced osteoclast differentiation and bone resorption [PDF]
Vav1 is a Rho/Rac guanine nucleotide exchange factor primarily expressed in hematopoietic cells. In this study, we investigated the potential role of Vav1 in osteoclast (OC) differentiation by comparing the ability of bone marrow mononuclear cells (BMMCs)

Interaction Between Actin and Microtubules During Plant Development
ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

The role of Rho GTPases in facial morphogenesis
The role of small GTPases, RHOA, RAC1, and CDC42 and pathway mediators is reviewed in the context of embryonic facial development. Lip fusion requires cytoskeletal remodeling during morphogenesis of the facial processes and during lip fusion. Fnm, frontonasal mass; lnp, lateral nasal process; mnp, medial nasal process; mxp, maxillary process; np, nasal

Effects of decreased Rac activity and malignant state on oral squamous cell carcinoma in vitro.
Rac proteins, members of the Rho family of small GTP-binding proteins, have been implicated in transducing a number of signals for various biological mechanisms, including cell cytoskeleton organization, transcription, proliferation, migration, and ...

Secretopathies emerge as a new class of neurocristopathies
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.
