The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

Hoxc13 is important for hair and tongue development by controlling hair keratin genes.

This study provides evidence that psychoemotional stress inhibits hair growth in mice by affecting the brain-hair follicle axis, with specific neuropeptides and treatments modulating this effect.

In this study, researchers identified novel LMNA mutations in patients with atypical progeroid syndrome, revealing clinical features distinct from other similar disorders, but unrelated to mutant prelamin A accumulation.

This study found that Oncostatin M, via JAK-STAT5 signaling, keeps hair follicle stem cells inactive, and its removal leads to hair growth initiation in mice.

In this mouse study, severe selenoprotein deficiency in epidermal cells was linked to skin abnormalities, disrupted hair follicle development, and progressive alopecia, highlighting the role of selenoproteins in skin and hair health.

This study found that parents of women with PCOS have a higher prevalence of insulin resistance and Type II diabetes than parents of healthy women.

This study found that organ-cultured human scalp hair follicles can mimic chemotherapy-induced damage in vivo and serve as a model to explore molecular targets and protective agents for hair follicle preservation.

This study suggests that there is a U-shaped relationship between vitamin D hormonal forms and aging, with an optimal serum calcidiol concentration needed to minimize aging-related chronic disease risk.

In this study, researchers found that p75 neurotrophin receptor signaling affects apoptosis during hair follicle regression in mice, and altering its activity might help manage disorders involving early catagen entry.

This study found that estrogen receptor beta plays a significant role in murine hair growth control, potentially acting as a silencer of estrogen receptor alpha's catagen-promoting effects.

This study created transgenic mouse models with the LMNA gene mutation common in Hutchinson-Gilford progeria syndrome, revealing skin and teeth abnormalities related to transgene expression levels.

Amenorrhea is relatively rare and initial testing should check FSH, TSH, and prolactin levels.

This article discusses the potential effects of exogenous testosterone, highlighting that its impact on prostate cancer progression, cardiovascular health, and behavior remains uncertain and needs further investigation.

This review discusses the various triggers and diagnostic challenges in determining the cause of telogen effluvium-related hair loss, without providing new clinical results.

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 review discusses the role of lamins in development, tissue maintenance, and stress response, and does not report new experimental findings.

This study reports that eliminating both Trp53 and Rb genes in mouse epidermis accelerates aggressive squamous cell carcinoma development due to early activation of the epidermal growth factor receptor/Akt pathway.

This article reviews various office treatments for common cosmetic issues but does not report any new clinical findings, focusing instead on discussing techniques like dermabrasion and chemical peels.

This study demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

This study found that activating Nrf2 in human hair follicles significantly reduced oxidative stress, lipid peroxidation, and protected against hair growth inhibition, suggesting a protective role for Nrf2 against redox insult in this context.

This study found that a specific mutation in the mouse RXRalpha gene significantly impacts immune responses and causes hair loss and skin cysts.

This study found no protective effect of topical calcipotriol on hair loss in chemotherapy patients, and the authors propose the term "atrophic telogen effluvium" for this type of hair loss.

This study observed that hair breakage may indicate early central centrifugal cicatricial alopecia in African American women, suggesting that it should be considered in their differential diagnosis.

This study found that autophagy plays a novel role in human hair growth, with altered autophagic flux during hair development phases influencing hair follicle behavior in a preclinical model.

This study suggests that myotonic dystrophies may qualify as segmental progeroid disorders due to molecular and clinical similarities with typical progeroid syndromes.

The researchers reported that in mice, prolactin signaling in the skin epithelium inhibits hair follicle stem cell activation, promoting quiescence during periods of high serum prolactin like pregnancy and lactation.

This review discusses the diagnostic criteria and guidelines for managing loose anagen syndrome and differentiating it from non-scarring alopecias, but it reports no new clinical results.

Blood tests confirmed a baby in the womb had a CMV infection.

This study found that Par3 plays a crucial role in maintaining epidermal homeostasis by regulating Rho/actomyosin contractility and ensuring mitotic accuracy, with potential implications for other self-renewing epithelia.
