This review discusses the challenges and opportunities in targeting the hedgehog pathway for aggressive cancers, emphasizing the complexities of treatment resistance, immune response, and the potential of combining immune checkpoint inhibitors with hedgehog pathway inhibitors, but reports no new clinical results.

This study identified a shared gene signature in scarring alopecia subtypes, with increased mast cell presence, suggesting similar treatment approaches may be effective across these hair loss disorders.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

This study observed significant differences in immune cell infiltration and gene expression across different skin sites, with the back displaying higher tolerance-promoting immune mechanisms, which may enhance epicutaneous immunotherapy outcomes.

This study found that in Pomeranians with Alopecia X, key genes in the Wnt and Shh signaling pathways and stem cell markers are downregulated, which may explain the absence of anagen hair follicles.

This study proposes that mammalian target of rapamycin (mTOR) may connect various signaling pathways in hair follicle tumor formation, offering a potential unified model for understanding these tumors.

This study found that their system effectively supports the rapid formation of human hair follicle organoids, providing a platform for studying hair regeneration and drug screening.

This study found that human hematopoietic mesenchymal stem cells increased the viability and migration of human outer root sheath cells in an in vitro alopecia areata model, involving Wnt/β-catenin and JAK/STAT pathways.

This study found that differentially expressed genes in horses with white versus black coats may regulate coat color, providing insights into the genetics of skin melanin synthesis.

This study found that a titrated extract of Centella asiatica enhanced the hair growth potential of 3D spheroid cultured human dermal papilla cells.

This study found that carvone, a plant-derived compound, decreases melanin content and inhibits melanoma cell proliferation through the cAMP pathway, suggesting potential benefits for treating melanomas and other hyperpigmentation disorders.

This study observed that 5% minoxidil topical foam alters gene expression and signaling pathways in the scalp, providing insights into its mechanism of action in men with androgenetic alopecia.

This study investigated the formation of Type III brush hair in Chinese Haimen goats and identified genetic factors that may involve heat stress in the process.

This review highlights that while sonidegib and vismodegib offer promising treatment options for advanced basal cell carcinoma, their use is often limited by treatment-emergent adverse events, which can be managed through protocol modifications and supportive interventions.

This study found that myristoleic acid promotes dermal papilla cell proliferation and anagen signaling through autophagy, cell cycle progression, and activation of the Wnt/β-catenin and ERK pathways.

This review discusses the role of YAP/TAZ proteins in skin cancer physiology and tumorigenesis, and the potential of targeting these proteins in skin cancer treatments, but presents no new experimental findings.

This study found that 5-bromo-3,4-dihydroxybenzaldehyde (BDB) promoted hair growth in rat vibrissa follicles by activating Wnt/β-catenin and autophagy pathways and inhibiting the TGF-β pathway in dermal papilla cells.

In this case report, a 62-year-old woman's persistent frontal fibrosing alopecia while on the psoriasis medication ustekinumab suggests that IL-12 and IL-23 inhibition may not be effective in treating this scarring alopecia, challenging the role of Th1 and Th17 pathways in its pathogenesis.

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.

This study identified key genes and signaling pathways involved in cashmere goat hair follicle growth cycles, influenced by melatonin implantation, suggesting a basis for further research on melatonin's regulatory mechanism.

In this study, miR-221 was identified as a key factor in androgenetic alopecia pathogenesis due to its role in suppressing hair growth by interacting with androgen receptors and affecting related pathways.

In a mouse model, this study found that nano-sized molybdenum accelerated hair growth and reduced oxidative stress markers, with enhancements observed when combined with minoxidil. It suggests potential for this combination as a novel topical treatment for hair loss, pending further clinical validation.

This study found that administering lower doses of sodium pentaborate pentahydrate increased hair growth in rats via specific molecular pathways, while a higher dose suppressed these pathways and impaired hair growth.
