This study found that activation of the TRPV3 ion channel inhibits human hair growth by affecting hair follicles and outer root sheath keratinocytes.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This review discusses recent advancements in hair rejuvenation strategies and assesses the potential of herbal drugs as safer alternatives, but reports no new clinical results.

This study found that the absence of the vitamin D receptor disrupts hair follicle structure during the first catagen in mice, linked to increased expression of the hairless gene.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

This study found that p53 plays a crucial role in regulating apoptosis during hair follicle regression (catagen) in mice, and its absence leads to delayed progression and altered expression of apoptosis-related markers.

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

This study found that overexpressing the BMP inhibitor Noggin in transgenic mice led to a significant loss of nontylotrich hair follicles, suggesting a critical role for BMP signaling in hair follicle morphogenesis and cycling.

This study found that overexpression of Wnt1a in bone marrow mesenchymal stem cells enhanced mouse hair follicle regeneration and promoted hair cycling.

In this study, UVB irradiation of organ-cultured human anagen hair follicles in vitro reduced hair elongation and increased cell death, affecting hair growth and regulatory processes.

This case study reported that absence of alopecia does not reliably predict responsiveness to vitamin D treatment in Vitamin D-dependent rickets type II, as demonstrated by a patient with normal hair growth who showed extreme resistance.

In this study, lipid peroxides were found to induce apoptosis in hair follicle cells and advance the catagen phase in mice, suggesting a potential mechanism for alopecia development.

This study found that overexpressing human Bcl-2 in mice protected epidermal keratinocytes from UVB-induced apoptosis but unexpectedly increased apoptosis during hair follicle regression and chemotherapy.

This review discusses polycystic ovary syndrome treatments, focusing on the potential benefits and safety of herbs and phytochemicals, and reports no new clinical results.

This article reviews the role of vasoactive intestinal peptide in maintaining immune privilege in hair follicles and does not report new findings; the authors propose it as essential for immune homeostasis in alopecia areata.

This review discusses the use of platelet-rich plasma for musculoskeletal pain relief and function improvement, but notes the current studies' limitations regarding methods and types of treatment.

This study found that ultraviolet radiation negatively affects hair follicle functions in human scalp skin, and caffeine application may provide some protective effects against this damage.

In this study, topical application of the SCD1 inhibitor XEN103 significantly reduced sebaceous gland size and number in mouse skin, suggesting potential local therapeutic effects for acne treatment without systemic side effects.

In this study, oral finasteride treatment for four weeks reduced the weight of the corpus cavernosum in rats but did not significantly affect erectile function.

This study found that deleting the Hes1 gene disrupts hair regeneration by delaying anagen initiation and shortening the anagen phase, suggesting it's crucial for maintaining hair cycle homeostasis.

This study concluded that administering dutasteride for more than 8 weeks in rats could lead to irreversible erectile dysfunction, even after stopping the medication.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

In this study, topical 5% roxithromycin was effective in restoring hair growth in about half of individuals with androgenetic alopecia without causing adverse effects.

In this study, treatment with DHEA induced mild to moderate hyperplasia of sebaceous glands in ovariectomized rats, which was prevented by the antiandrogen Flutamide but not by the antiestrogen EM-800.

This article discusses the potential for topical caffeine as a natural alternative for treating androgenetic alopecia due to its ability to penetrate skin, but it reports no new clinical findings.

This article describes the immunofluorescence tomography method to achieve high-resolution 3-D reconstruction of epithelial tissues and reports no clinical results.

This study presents evidence that specific thymus-derived peptides affect human hair follicle growth, identifying thymulin as a potential hair growth stimulator despite interindividual response variations.

This review summarizes major growth factors that promote hair follicle growth, but it reports no new experimental findings.

This study found that Origanum vulgare extract improved testicular structure and function in mice against finasteride-induced damage by enhancing antioxidant defense and modulating gene expression related to apoptosis.

This review discusses the potential application of platelet-rich plasma (PRP) therapy as a regenerative treatment approach, particularly as an alternative and complementary therapy for severe respiratory conditions, though clinical protocols are needed to verify its efficacy.
