This study used developing mouse hair follicles to explore early epithelial bud formation, finding that the Rho GTPase regulator ARHGEF3 plays a crucial role in regulating cell fate and cadherin patterning, with knockouts showing disrupted morphology and increased straight hair follicle growth.

This study found that a catalytically active version of Vav2 significantly altered gene expression patterns in hair follicle stem cells in mice, with these changes varying over the animals' lifespans.

This article reviews methods for examining the localization and activity of ROP GTPase, cortical microtubule organization, and F-actin dynamics in plant cell models, but reports no new experimental results.

This study found that Rac1 is crucial for maintaining the integrity of hair follicle structure but is not needed for skin epidermis maintenance in mice.

This study found that epithelial cells in the skin of live mice regulate the density and spatial organization of immune cells, which actively maintain their position despite constant cell turnover.

This study analyzed gene expression in Pashmina goats and identified key biological processes and molecular functions involved in long-fibre production, suggesting potential pathways for enhancing this trait in other goat breeds.

This study found that Rac1 activity in specific skin compartments is sufficient for hair formation, but results in hair with altered structure and pigmentation compared to normal.

This study identifies specific molecular components involved in the intracellular trafficking of LGR5, revealing mechanisms that differ from typical GPCR recycling processes.

This study found that ILK/ELMO2 complexes in epidermal keratinocytes are selectively activated by epidermal growth factor to induce cell migration, unlike with other growth factors.

This study found that low temperatures and nitrogen deficiency trigger root hair elongation through a molecular mechanism involving the receptor kinase FERONIA and the TOR Complex 1.

This study suggests that CD151-integrin complexes inhibit epithelial cell migration, and that disruption of these complexes enhances migration, regulated by Rho GTPase activation differences on distinct laminins.

This study reports that localized Rho GTPase activity and ROS production play a critical role in polarized growth and movement in both migrating endothelial cells and developing plant root hairs.

This study suggests that disruptions in the Ran system related to nuclear transport may be a key factor in the development of cellular issues in Hutchinson Gilford Progeria Syndrome.

This review highlights the role of reactive oxygen species in root hair growth and cell expansion in plants but does not report new empirical findings.

In this study, the authors reported that AtRXR3, a phosphorus-inducible DUF506 protein, modulates root hair growth under phosphorus stress by interacting with calmodulin and influencing calcium oscillations.

This study identified genetic variations associated with black and white wool color in Gangba sheep, enhancing understanding of wool color genetics and aiding selective breeding for specific wool colors in Tibetan sheep.

This study found that vimentin is essential for proper wound healing and cell growth by influencing EMT signaling and mTOR activity in mice.

This study identified hair follicle stem cells as a source of squamous cell carcinoma in an inducible mouse model and proposes targeting these for future cancer therapies.

This study found that deleting the CD98hc protein in mouse skin impairs wound healing and homeostasis, resembling aging effects, due to disrupted integrin signaling pathways.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

This review examines PAK4 signaling pathways in prostate cancer, Parkinson's disease, and melanogenesis, focusing on the potential role of the PAK4-CREB axis, without reporting new clinical results.

In this study, enteroendocrine cells were shown to coordinate intestinal stem cell migration towards a wound in Drosophila by releasing a ligand that activates non-canonical Wnt signaling, aiding efficient tissue repair.

AGD1 is important for root hair development in Arabidopsis, working with phosphoinositide signaling and the actin cytoskeleton.

This research suggests that the barley protein RACB supports cell polarity functions rather than interfering with immunity, as it aids nucleus positioning during fungal attack rather than affecting early immune responses.

This study found that ion-paired solutions significantly improved the skin penetration of risedronate in hairless mice compared to risedronate alone.

This study found that conditional knockout of N-WASP in keratinocytes of mice led to skin barrier defects, increased immune cell infiltration, and hyperproliferation of keratinocytes, indicating its crucial role in skin homeostasis.

In this study, researchers discovered that ROR2, a Wnt receptor, plays a crucial role in regulating hair follicle stem cell self-renewal and maintenance, compensating for the absence of β-catenin.

In this study, activation of oncogenic K-ras in a mouse model caused the oral mucosa to rapidly progress from squamous hyperplasia to carcinoma within 14 days, demonstrating its acute sensitivity.

In this study, researchers found that AGD1 is crucial for membrane recruitment during root hair development in Arabidopsis thaliana, with its pleckstrin homology domain essential for targeting specific plasma membrane regions.

This study identified proteins that are differentially expressed in balding versus non-balding dermal papilla cells, potentially aiding the understanding and treatment of androgenetic alopecia.
