This review discusses the critical role of BMP signaling in the development and regulation of skin and hair follicles and notes that further research could aid therapeutic advances; it presents no new clinical results.

This study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

This study found that ocu-miR-205 affects signaling pathways, promoting the apoptosis of dermal papilla cells and influencing hair follicle density in Rex rabbits.

This review discusses epithelial-mesenchymal interactions in hair follicle development and their regulation by molecular signals, but reports no new results; the authors emphasize the need for further research to apply these findings clinically.

This review highlights potential therapeutic mechanisms of natural products for androgenetic alopecia, suggesting they may modulate signaling pathways and have anti-inflammatory and antioxidant effects.

This study identified mefloquine as a potent inducer of lethal ER stress that effectively eliminated vemurafenib-resistant and sensitive melanoma cells, suggesting its potential for repurposing as a melanoma treatment.

This article reviews the role of skin appendages in wound healing and appendage regeneration, discussing cellular and molecular mechanisms but reports no new experimental findings.

This study found that TRPV3 ion channels on human epidermal keratinocytes suppress cell proliferation, induce cell death, and trigger a proinflammatory response, suggesting a role in cutaneous inflammatory processes.

This study found that normal human melanocytes can be protected from apoptosis through both PI 3-kinase/Akt-dependent and independent pathways, with insulin and TPA offering nearly complete protection.

This study found that WWOX deficiency in mice leads to impaired skin development, reduced epidermal thickness, and significant hypothermia due to disrupted cell proliferation and homeostasis.

This study reported that in mouse models, deletion of EGFR resulted in stem cell hyper-proliferation followed by apoptosis, leading to scarring alopecia, and implicated EGFR's role in maintaining hair follicle quiescence and immune privilege during inflammation.

This study found that Danthron induced apoptosis in a human malignant melanoma cell line through mitochondrial, endoplasmic reticulum, and death receptor pathways.

This study observed that exosomes from adipose-derived stem cells promoted hair growth by enhancing dermal papilla cell proliferation and activating signaling pathways, suggesting potential for treating immune-mediated alopecia.

This study demonstrated that a ligand-independent action of the vitamin D receptor significantly affects keratinocyte behavior in hair follicles and skin, pointing to its crucial role in maintaining normal hair and skin structures in rats.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

Results are not reported in this abstract, which outlines research investigating why diabetic mice experience suppressed hair follicle stem cell activation, potentially contributing to chronic diabetic wounds.

This study found that topical trypsin application after hair removal in mice led to cell death at the follicular papilla, which delayed hair growth and pigmentation.

In this study, researchers found that activating the delta opioid receptor with a specific agonist significantly promoted hair growth in mice, suggesting potential for developing new hair-loss treatments.

This review discusses the potential of ginseng and its metabolites for treating hair loss and reports no new clinical findings.

In this study, researchers observed that patients with androgenetic alopecia show differences in scalp microbial communities compared to the general population, including an increase in Cutibacterium acnes, particularly in males, which may interact with lipid and immune pathways to contribute to hair follicle miniaturization.

This study found that exosomes derived from dermal papilla cells can enhance the proliferation of hair follicle stem cells by stimulating the LEF1 pathway, offering insights into hair follicle growth regulation.

This study found that minoxidil stimulates the Kir6.2/SUR2 potassium channel, leading to tumor growth arrest in an ovarian cancer xenograft model by disrupting mitochondrial function and inducing cell death.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

This study mapped a detailed genetic profile of goat hair follicle apoptosis, identifying key genes and regulatory factors involved in the hair cycle, offering new insights into programmed cell death.

This study observed that reduced activation of SMAD2/3 proteins in cutaneous squamous cell carcinoma tissue compared to adjacent tissue may indicate a tumor suppressor role in disease progression.

This review discusses how targeting apoptosis pathways in hair and skin cells can inform the development of novel therapies, but it reports no clinical findings.

This review examines androgenetic alopecia, detailing its causes and current treatments, but reports no new clinical results; the authors emphasize understanding its complexity for personalized therapy development.

In this study, topical application of Angelica sinensis extract on mice promoted hair regrowth by influencing key hair cycle pathways and reducing keratinocyte apoptosis during the catagen phase.

In this study, ebastine significantly increased the proliferation of human follicle dermal papilla cells and may contribute to hair regrowth by activating the ERK signaling pathway.

This review discusses how TGF-β3 influences fate decisions of various stem cell types, highlighting its role in proliferation, differentiation, and cell death through classical and non-classical signalling pathways.
