In this study, researchers report that CDK inhibitors like palbociclib and ribociclib, initially developed for cancer therapy, show potential in treating neutrophilic inflammation-related conditions such as ARDS and psoriasis, although their clinical repurposing requires further research on safety and dose adjustments.

This study found that ablating cyclin D3 in a Ras-dependent skin carcinogenesis model increased apoptosis in hair follicles, reducing papilloma development but potentially facilitating malignant progression when CDK6 is overexpressed.

This study found that altering cyclin-dependent kinase 4 (CDK4) levels in the bulge region of hair follicles affects the balance of stem cell numbers, potentially influencing hair follicle self-renewal and proliferation.

This study found that epidermal growth factor significantly enhances the proliferation of hair follicle-derived mesenchymal stem cells through the EGFR/ERK and AKT pathways, without involving the STAT3 pathway.

This study found that CDK4/6 inhibitors in hormone-positive metastatic breast cancer were linked to increased risks of fatigue, alopecia, and stomatitis compared to placebo.

This study found that RhoA influences embryonic stem cell proliferation through the PKN1-cyclin D1 pathway in vitro, suggesting RhoA as a potential target for wound healing therapies.

In this study, circ-Smad5 was found to inhibit the proliferation and cell cycle progression of JB6 cells by suppressing Wnt/β-catenin/Lef 1 signaling activation, marking the first report of its function.

This study found that the expressions of CDK inhibitors p21waf1/cip1 and p27kip1 were higher during the anagen phase compared to telogen, suggesting a role in follicular epithelial cell differentiation.

This study found that CDK4/6 inhibitors for HR+/HER2- advanced breast cancer are linked to typical adverse events such as fatigue and neutropenia, while also identifying unexpected reactions, highlighting potential safety concerns in their real-world use.

In this multicentric retrospective study, researchers reported that cutaneous adverse events were common among advanced breast cancer patients treated with cyclin-dependent kinase inhibitors (CDK4/6i), generally mild, and manageable with topical treatments, though in some cases, they led to treatment discontinuation.

In this research on cinnamon and virgin coconut oil hair tonics, F2 and F3 demonstrated stable physical properties and mild irritation potential, while formula 1 remained non-irritating but less stable regarding pH and viscosity.

This study suggests that FGF18 may enhance radioresistance in telogen hair follicles by inducing cell cycle arrest, potentially serving as a radioprotector against radiation-induced hair follicle damage.

This study found that altering CDK4 expression in mice affects the population of keratinocyte stem cells, suggesting a correlation with susceptibility to skin papillomas.

This study demonstrated that the highly divergent WDSV rv-cyclin significantly stimulates eukaryotic cell proliferation, leading to hyperplastic skin lesions in transgenic mice.

In this study, researchers found that the number of dermal papilla cells in hair follicles determines hair size and shape in mice, suggesting potential avenues for addressing hair loss.

In this study, Msx2-deficient mice showed progressive hair loss due to shortened anagen phase and prolonged catagen and telogen phases, resulting in cyclic alopecia with structurally abnormal hair shafts.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This paper argues that the cycling hair follicle serves as a valuable model for systems biology research, highlighting its potential for translational medicine.

This study reported that deleting the MED1 subunit from the MED complex in keratinocytes resulted in disrupted hair differentiation and cycling, leading to hair loss in mice.

This research found that activating a KrasG12D mutation in mice led to skin thickening, papillomas, and hair growth issues, suggesting that even rare KRAS mutations can mimic human RAS/MAPK syndrome symptoms.

This study found that Foxp1, a transcriptional factor, plays a key role in regulating hair follicle stem cell proliferation by modulating oxidative stress and the cell cycle during hair growth phases.

In this case study, a girl with hereditary vitamin D resistant rickets had a novel mutation in the VDR gene that affected hair cycling without causing total alopecia, suggesting ligand-independent VDR function in hair cycling.

This study found that MED1 plays a role in maintaining keratinocyte quiescence and hair follicle stem cell populations, as its absence in mice led to increased keratinocyte proliferation and reduced stem cell numbers.

In this study, kartogenin promoted hair growth by enhancing cell proliferation and migration in vitro and extended hair length in mice, suggesting its potential as a treatment for hair loss.

This study observed distinct sex differences in hair growth cycles and regeneration in C3H/He mice, noting that females regenerated hair faster after adhesive material application, whereas males were more reliant on macrophage activity for this process.

This study found that perifollicular vascularization around the dermal papilla adjusts dynamically to physiological changes, with minoxidil enhancing vessel mobilization and aging processes inhibiting it, highlighting potential targets for treating hair loss and skin aging.

This study found that perifollicular vascularization adapts to physiological changes, with minoxidil enhancing capillary growth around the dermal papilla and aging-related factors inhibiting it, suggesting potential interventions for hair loss.

This study suggests that the Leptin receptor may serve as a novel cell surface marker for dermal papilla cells, potentially aiding future isolation and research efforts in hair follicle regeneration studies.
