This review discusses WHO group 2 anovulation, highlighting polycystic ovary syndrome as a common cause of infertility and noting current treatment options without presenting new clinical results.

This study found that BMP-2 activates Dlx3 gene transcription in murine keratinocytes by binding with Smad1/Smad4, suggesting a mechanism for BMP signaling's role in skin and hair follicle regulation.

This study found that PRC2 plays a crucial role in maintaining intestinal homeostasis by supporting progenitor cell proliferation and limiting secretory lineage differentiation.

This study demonstrated that high oral doses of finasteride caused external genital abnormalities in male rhesus monkey fetuses, but intravenous doses did not lead to abnormalities.

This background review discusses alopecia areata, highlighting the role of CD8+NKG2D+ T cells in hair follicle pathogenesis, and notes that the exact mechanisms causing hair loss remain unclear.

This study found that overexpression of the transcription factor Tcf3 accelerates keratinocyte migration and skin wound healing in mice, highlighting its potential as a therapeutic target for wound repair.

This review discusses the origins of skin and esophageal cancers and reports no clinical results; it emphasizes the role of cyclooxygenase-2 in tumorigenesis and differentiation.

In this study, cisplatin was found to induce cell death in human hair follicle cells through hydroxyl radical generation and Bcl-2 down-regulation, suggesting potential strategies for preventing chemotherapy-induced alopecia.

This study found that hyperandrogenemia in Chinese women with PCOS is associated with higher risks of type 2 diabetes and obesity, suggesting it should be prioritized in managing PCOS-related infertility.

This letter discusses the limited treatment options for pediatric alopecia areata and the lack of controlled studies for therapies like systemic and off-label immunosuppressive drugs, without reporting new clinical results.

Type I keratin genes are closely linked to the rex locus on mouse chromosome 11, affecting hair development.

Tofacitinib 2% ointment helped hair regrow in 3 out of 10 patients with alopecia areata, but caused side effects like scalp irritation and raised cholesterol in some.

This study found that KAP7.1 and KAP8.2 genes were significantly more expressed in secondary hair follicles than primary follicles, suggesting their role in regulating cashmere fiber diameter.

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 study found that finasteride at 1 mg/day was the most effective dose for treating male pattern hair loss, with similar efficacy to 5 mg/day and better results than lower doses.

This study found that nanoemulsion-based formulations, such as nanoemulgel and NFs, might serve as promising topical delivery systems for treating inflammatory diseases, potentially offering an alternative to traditional nonsteroidal anti-inflammatory drugs, which are associated with adverse effects.

This study found that SRD5a-3 is a highly efficient enzyme for converting hormones into androgens, with dutasteride being a much more potent inhibitor of SRD5a-3 than SRD5a-2.

This study found that sebaceous glands predominantly exhibit oxidative activity of the type 2 17β-hydroxysteroid dehydrogenase isozyme, which is not inhibited by 13-cis retinoic acid.

This study used a new statistical approach, PLACO, to identify several novel shared genetic regions associated with both Type 2 Diabetes and Prostate Cancer in two large GWAS datasets.

This study observed that PAI-2 is consistently expressed in differentiating cells of murine hair and nail, suggesting it may function as a marker of differentiation and possibly protect against premature cell death.

This study suggests that the COX-2 enzyme plays a role in hair follicle biology, as transgenic overexpression in mice induced hair follicle cycling disturbances and alopecia, which was mitigated by COX-2 inhibition.

In this study, photodynamic therapy significantly reduced inflammatory acne lesions and sebum secretion, possibly by inducing apoptosis in sebaceous glands and down-regulating TLR-2 and TLR-4 expression.

This study observed that VEGF165 increases proliferation and migration but alters adhesion properties of cultured human hair follicle cells, indicating a potential role for VEGF/VEGFR-2 in hair follicle regulation beyond angiogenesis.

This study found that overexpressing PKCδ in transgenic mice did not reduce squamous cell carcinoma development induced by UV radiation, despite its effectiveness against TPA-promoted cancer in these mice.

This study found that activating the erbB-2 oncogene in transgenic mice led to severe skin abnormalities and fatal defects, indicating erbB-2's significant role in skin and hair follicle development.

In this study, l-Ascorbic acid 2-phosphate was found to stimulate hair follicle growth in vitro by promoting IGF-1 expression via the PI3K pathway.

This article reviews the molecular interactions involved in hair follicle cycling and highlights the role of dermal papilla cells, but it presents no new research findings.

This study identified a new enzyme, skin l‐tryptophan‐2,3‐dioxygenase, that may play a role in rat hair growth regulation, showing increased activity during peak hair growth periods.

This letter to the editor discusses a potential link between new onset alopecia areata and SARS-CoV-2 infection, but reports no new clinical results.

This study found that radiofrequency treatment, with or without hydrolyzed collagen, increased dermis thickness, neocollagenesis, and FGF2 overexpression in rat skin tissue.
