In this study, researchers found that recombinant human HAPLN1 promoted hair growth in mice and human hair matrix cells by activating specific signaling pathways, suggesting it may offer a potential hair loss treatment with fewer side effects than existing medications.

This study found that the RNA helicase DDX6 is essential for maintaining self-renewal in epidermal progenitor cells by promoting the translation of proliferation regulators and degrading differentiation-inducing mRNAs.

This study found significant differences in mRNA and miRNA expression between yak dermal papilla cells and epidermal hair matrix cells, suggesting important roles for these molecules in hair follicle development.

This study found that ARHGEF3 is crucial for hair follicle development in mice, as its absence leads to defects in placode compaction and impaired follicle downgrowth, highlighting its role in regulating cell shape rearrangements during embryogenesis.

This study found that the enzyme encoded by Dgat1 acts as a retinol acyltransferase in murine epidermis, protecting against retinoid toxicity and alopecia by preventing retinol accumulation.

This study found that targeting mTORC1 with rapamycin effectively inhibited skin tumor promotion in a mouse model, highlighting a potential target for cancer chemoprevention.

This study found that transgenic mice expressing a mutant E1a oncoprotein in their skin had disturbed hair follicle maturation but did not show increased tumor development or proliferation.

This study identifies two previously unreported pathogenic RIPK4 gene variants, suggesting a functional link with cell adhesion molecules in ectodermal dysplasias.

This study constructed a single-cell atlas of hair follicle cells from yaks and taurine cattle, revealing that differences in WNT signaling within dermal papilla cells may be key to the yak's adaptation to cold environments on the Qinghai-Tibet Plateau.

This study found that EGR1 promotes the proliferation of dermal papilla cells, suggesting its close association with hair follicle growth and development.

This study found that PBX1 overexpression reduces hair follicle-derived mesenchymal stem cell senescence and apoptosis by alleviating ROS-mediated DNA damage, rather than enhancing DNA repair.

In this study, the authors found that targeting mTORC1 with rapamycin inhibited TPA-induced skin tumor promotion by affecting keratinocyte proliferation, including critical stem cell populations in the mouse epidermis.

This study showed that knocking out the Ppp2ca gene in the epidermis of mice led to significant hair loss and disrupted hair follicle morphogenesis and regeneration.

This study identified intramembrane proteolysis as a key feature of Astrotactin2 maturation, providing insights into its role in planar cell polarity hair patterning.

This study found that the desmosomal protein desmoplakin is crucial for proper epidermal morphogenesis and radial intercalation in developing Xenopus embryos, affecting keratin organization and ectodermal structures.

This study found that deleting the transcription factor Twist1 in keratinocytes significantly reduced UVB-induced skin carcinogenesis in mice, suggesting a potential target for preventing cutaneous squamous cell carcinoma.

In this study of pediatric melanocytic lesions, researchers at Massachusetts General Hospital observed no concurrent BAP1 loss and BRAFV600E positivity, characteristics of adult BIMT, suggesting that these tumors may develop at a later age rather than in childhood.

This study demonstrated that in live rodents, actin filaments adjust their structure to facilitate membrane transfer between cellular compartments with different biophysical properties.

This study found that the N-terminal fragment of AIMP1 enhances hair growth and proliferation of hair follicle stem cells in mice, suggesting its potential as a therapeutic peptide for hair loss treatment.

This study identified that Eda-A1 unexpectedly induces placode inhibitors dkk4 and lrp4, indicating the importance of tightly regulated signaling for proper ectodermal organ development.

This study identified and characterized a gene called 4C32, which is expressed in the periderm of embryonic mouse skin and has a structure similar to keratin-associated proteins.

Mutations in β1 integrins cause embryonic death but have milder effects on skin.

This study found that KAP7.1 and KAP8.2 genes were significantly more expressed in secondary hair follicles than primary follicles, suggesting their role in regulating cashmere fiber diameter.

This study found that rapamycin effectively inhibits TPA-induced keratinocyte proliferation and skin tumor promotion by targeting mTORC1 signaling in both wild-type and transgenic mice.

This study suggests that the transcription factor PDF2 in Arabidopsis may link lipid sensing with growth responses to phosphate starvation by acting as a sensor for lyso-PCs through its START domain.

This study reports that lower levels of N-myc mRNA are observed when hair growth ceases in certain phases in mice, and attempts to create transgenic mice for further investigation resulted in high embryonic mortality.
