In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

In this study, researchers found that autophagy is crucial for maintaining the mature protein composition of hair shafts, with its disruption leading to increased levels of various proteins, suggesting potential diagnostic applications for detecting impaired autophagy through hair proteomic analysis.

This study suggests that epidermal turnover could be a regulated mechanism of iron excretion, with systemic iron levels influencing keratinocyte behavior and differentiation markers in the skin.

This study observed that melanogenesis in human hair follicles is linked to anagen phases, with melanocyte activity and enzyme expression being region-specific to the nascent bulb.

In this study, the researchers identified a temperature-sensitive mutant in Arabidopsis thaliana, showing disrupted root hair formation and altered responses to plant hormone treatments at elevated temperatures.

In this study, researchers identified a temperature-sensitive mutation in the FERONIA gene of plants that prevents root hair formation at elevated temperatures, highlighting its role in maintaining root hair growth and response to plant hormones.

This study found that tight junctions extend to the most superficial layer of the stratum granulosum in human skin, challenging previous claims of their limited presence in the epidermis.

This study found that blocking autophagy in Atg7-deficient mouse hair keratinocytes altered the molecular composition of hair shafts by increasing the abundance of proteins involved in protein turnover while keratins remained unchanged, highlighting autophagy's role in reducing non-cytoskeletal protein concentrations in hair.

This study examined the effects of six surfactants on hair and scalp, finding varying irritation levels and impacts on protein denaturation and scalp turnover time, with AMT suggested as a good detergent.

This study found that long-lived proteins in mice, identified across various tissues, may be linked to neurodegenerative and cardiovascular diseases due to their low renewal rate and increased risk of damage.

This review discusses the potential of mesenchymal stem/stromal cells and their exosomes in promoting wound healing and skin regeneration, but reports no new experimental results.

This study uncovered how Staphylococcus hominis transports an odor precursor molecule, potentially leading to new ways to control body odor production in humans.

This study reports that a specific transporter protein in Staphylococcus hominis is responsible for transporting a malodour precursor, thereby playing a key role in human body odor production.

The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.

This study identified KLHL24 as a new gene linked to a subtype of epidermolysis bullosa simplex, highlighting its role in unresolved cases by involving a degradation-resistant truncated protein impacting keratin turnover.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

This study concluded that MEX3A is critical for maintaining Lgr5+ intestinal stem cells by regulating the PPARγ pathway, impacting intestinal homeostasis during postnatal development in mice.
