The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

This review discusses current concepts in wound repair and suggests that these evolving paradigms might also explain regenerative processes in various organ systems, but it reports no new research findings.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

This study found that the subtilisin protease Sub3 from Microsporum canis is essential for adherence to the feline epidermis but is not necessary for invading epidermal structures.

This abstract contains no research results; it provides information about the JAMA Dermatology journal and its access options.

This research describes a process for producing caffeine nanocrystals, which may enhance skin penetration by accumulating in hair follicles and maintaining stability for two months, paving the way for in vivo testing.

This study found that DNA strand segregation in multipotent hair follicle stem cells occurs randomly during development and tissue homeostasis, challenging the immortal strand hypothesis.

This article reviews hair analysis for drug detection and its applications in various fields, but reports no new research findings, emphasizing the need to consider the method's complexities and potential pitfalls.

This study found that high-dose oral zinc significantly influences hair growth in mice, showing both inhibition and promotion effects depending on the timing and duration of administration.

This review discusses potential mechanisms contributing to higher COVID-19 mortality among men, particularly the roles of smoking, genetic factors, and reproductive hormones, without presenting new clinical findings.

This review examines the roles of Smad-4 and Smad-7 in hair follicle differentiation and development through BMP signaling and TGFβ/Activin/BMP pathway inhibition but reports no new experimental results.

This study successfully developed a reproducible mouse model demonstrating fetal scarless wound healing, which may provide insights for minimizing scarring in adults.

This study utilized a sequence-structure alignment approach to improve the characterization of Class A Rhodopsin GPCR superfamily, including orphan and unclassified receptors, through evolutionary analysis.

In this animal study, topical minoxidil shortened the telogen phase of hair growth cycles in rats, suggesting it may stimulate certain follicles to progress more rapidly to anagen.

This review discusses the use of platelet lysate and its growth factors in treating diseases and regenerative medicine but reports no new clinical findings.

This study screened synthesized pyridinecarboxamides for antitumor properties and found that many, particularly 5c and 7a, showed moderate in vitro activity against various human tumor cell lines.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

In this cell study, Eclipta alba extract inhibited cancer cell proliferation and induced apoptosis, showing potential antiproliferative and anti-metastasis effects on liver and related cancer cell lines.

Genes and hormones cause hair loss, with four genes contributing equally.

This study found that after injury, the bone marrow microenvironment's increased Wnt10b expression supports hematopoietic stem cell regeneration by enhancing Wnt signaling, revealing a vital interaction during recovery.

This review summarizes the application of microneedles in treating various skin diseases and highlights challenges like low drug loading, noting no new clinical results are reported.

This article reviews emerging treatments for androgenetic alopecia, including topical 5-alpha-reductase inhibitors and prostaglandin modulators, but reports no clinical results and calls for further efficacy evidence, especially for PRP.

This study concluded that polymeric nanoparticles effectively targeted hair follicles for drug delivery, but the organogel formulation did not enhance their penetration into the hair shaft.
