This review discusses persistent adverse effects of 5α‐reductase inhibitors, like diminished libido and erectile dysfunction, in some patients and highlights the need for patient discussions before therapy, especially for androgenetic alopecia.

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.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

This study found that dermoscopic indicators like black dots and tapering hairs are valuable markers for diagnosing and assessing the severity and activity of alopecia areata in Asian patients.

This study demonstrated that blocking the Sonic hedgehog signaling pathway in mice led to reversible inhibition of body coat hair morphogenesis, while whisker development was unaffected.

Fungi-produced compounds can change plant root growth.

This review discusses the role of the sonic hedgehog pathway in skin development and cancer, highlighting its potential as a target for chemoprevention and treatment; it reports no new findings.

This review outlines various dermatologic adverse events associated with targeted therapies and immunotherapies, emphasizing the need for collaboration between dermatologists and oncologists to manage these effects effectively; it reports no new clinical findings.

This review discusses the cutaneous symptoms associated with COVID-19 and their potential use in diagnosing and assessing the severity of the disease, but it reports no new clinical results.

This study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.

This study found that active BMP signaling prevents epithelial stem cell activation and expansion in hair follicles, while its inhibition leads to HF stem/progenitor cell overproduction and matricomas.

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 found that manipulating Wnt signaling pathways in cutaneous wounds can induce skin structures resembling regeneration, suggesting a potential role for Wnt signals in restoring skin architecture during wound healing.

The enzyme PA-PLA1α is important for proper hair follicle development.

This review discusses the WNT signaling pathway's involvement in human diseases and highlights recent advances in WNT-related treatments, but it presents no new research findings.

This review discusses the role of the endocannabinoid system in skin health and disease, highlighting its potential for future research and applications, but reports no new experimental results.

This review argues that the immunocompetence hypothesis, linking masculine facial features to attractiveness through health benefits, lacks sufficient evidence and sidesteps alternative explanations.

In this study, researchers found that transgenic expression of the Hairless gene in keratinocytes can restore hair follicle regeneration in Hr-deficient mice by repressing Wise, a modulator of Wnt signaling.

This review discusses recent advancements in scar reduction techniques, highlighting promising therapeutic targets and the role of Wnt/β-catenin signaling in promoting scarless wound healing, but reports no new clinical results.

This study found that in mice, epidermal Wnt/β-catenin signaling influences adipocyte differentiation and hair growth, suggesting its critical role in synchronizing adipogenesis with the hair growth cycle.

This review discusses the dermatologic symptoms associated with severe eating disorders like anorexia nervosa and bulimia nervosa and how they can aid in early diagnosis, without reporting new results.

This study concluded that higher androgen levels in males and specific skeletal sites may contribute to differences in skeletal morphology, with glucocorticoids, E2, and D3 enhancing androgen receptor expression and mitogenic action in human osteoblastic cells.

This study reported a 6.3% prevalence of PCOS among women in a Sri Lankan community, with most cases presenting as oligo/amenorrhea and polycystic ovaries.

This study observed a high prevalence of androgenetic alopecia in patients hospitalized with severe COVID-19, with 79% of men and 42% of women affected, suggesting a potential link between androgen sensitivity and COVID-19 severity.

This study found that the protein MIM is crucial for maintaining cilia and Sonic hedgehog signaling in mesenchymal cells by counteracting Src-mediated phosphorylation of Cortactin, impacting hair follicle formation.

This study identified that Eda-A1 unexpectedly induces placode inhibitors dkk4 and lrp4, indicating the importance of tightly regulated signaling for proper ectodermal organ development.

This study reports that Iressa, an anti-cancer agent, commonly causes acneiform eruptions and xerosis as cutaneous side effects, similar to other agents targeting epidermal growth factor receptors.

The authors concluded that the dermal response to epidermal Wnt/β-catenin signaling depends on distinct fibroblast lineages, with each responding to different paracrine signals such as Hedgehog and TGF-β.

This study found that KSR1 is necessary for v-Ha-ras-mediated skin tumor formation but not for MT-driven mammary cancer, indicating its potential as a therapeutic target in Ras/MAPK signaling-related tumors.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.
