This study found that overexpression of ornithine decarboxylase and activated Ha-ras together led to a high rate of tumor development in a mouse model without additional carcinogens.

This study suggests that IGFBP-2 may play a role in basal cell carcinoma development by mediating epidermal progenitor cell expansion in hair follicles with activated Shh signaling.

This study found that baricitinib, a Janus kinase inhibitor, was more effective than traditional treatments for severe alopecia areata, with higher rates of significant hair regrowth after 6 months, despite mild-to-moderate side effects and some instances of weight gain.

This study found that inhibiting AP-1 transcription factors in mice causes squamous tumors to transform into sebaceous tumors and regulates tumor cell lineage.

This study suggests that the CXCL8 gene may regulate cashmere fineness in Liaoning cashmere goats, providing new insights into the cellular mechanisms of cashmere growth and quality.

In a mouse model of chemotherapy-induced alopecia, this study found that enhancing ETV2 expression improved angiogenesis and hair regrowth following 5-fluorouracil treatment.

In this study, researchers found that TCDD exposure accelerated differentiation and altered gene expression in human epidermal cells, indicating the epidermal barrier as a target of TCDD-activated AHR.

This study found that Atlantic croaker nuclear androgen receptors AR1 and AR2 have different binding affinities for androgens, suggesting that they may mediate distinct physiological actions in teleosts.

In this multicenter retrospective study, 61.5% of Italian patients with severe alopecia areata achieved significant hair improvement after 52 weeks of treatment with baricitinib, with no major safety issues reported, indicating long-term effectiveness in a real-world setting.

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.

In this ongoing phase 3 study, ritlecitinib demonstrated sustained efficacy up to 24 months in patients aged 12 or older with alopecia areata, showing increased response rates with or without an initial loading dose and supporting its long-term use.

This study observed that in mouse hair follicles, enzymes Aldh1a2 and Aldh1a3 have distinct expression patterns that suggest they are involved in different signaling pathways during the hair cycle.

In this retrospective study, researchers found that baricitinib was effective for treating moderate to severe alopecia areata, with response rates in 24 patients comparable to existing real-world data, and no new safety concerns were identified.

This study found that male 5α-reductase 2 knockout mice showed deficits in social dominance behaviors and reduced dopamine receptor binding in a brain region related to social ranking.

This study suggests that inactivation of β-catenin is necessary for chick retina regeneration, as it allows cells to enter the cell cycle during injury and promotes regeneration without needing FGF2.

In this study, the combination of two compounds activated AMPK levels in skin cells, reducing oxidative damage and improving energy production, which may support faster recovery and repair in aging skin.

In a Belgian cohort study, nearly 90% of alopecia areata patients treated with oral baricitinib experienced hair regrowth, with more than 70% achieving a favorable SALT score, particularly in patchy cases, though some relapsed post-treatment. No serious adverse events were noted.

This article reviews and critiques Tamsin Wilton's arguments on MTF transsexualism, suggesting her work reaffirms Cartesian dualism rather than dismantling it, and emphasizes the need for continued dialogue in transsex, lesbian, and feminist communities.

This study found that baricitinib, taken for 24 weeks, significantly reduced alopecia severity in patients with moderate-to-severe alopecia areata, with 50% showing marked improvement and overall favorable safety and efficacy reported.

This study found that activin B promotes epithelial wound healing in mice through the RhoA-Rock-JNK-cJun signaling pathway, suggesting a potential therapeutic role for activin B in wound repair.

This study found that prostaglandin E2 pretreatment may reduce radiotherapy-induced alopecia by enhancing hair follicle self-repair through transient G1 arrest, suggesting a potential preventive treatment.

This study found no significant difference in the therapeutic response to intralesional triamcinolone acetonide at concentrations of 2.5, 5, and 10 mg/mL for various dermatologic conditions.

This article discusses the effects of ablative carbon dioxide laser treatment for skin rejuvenation, noting it requires only a single treatment but involves more complex postoperative management, without reporting new clinical outcomes.

Baricitinib stops hair loss and promotes regrowth in alopecia areata.

Ritlecitinib significantly regrows scalp hair in people with alopecia areata.

This study found that prostaglandin D2 increases testosterone production in human keratinocytes through a mechanism involving ROS and REDOX potential, which could inform treatments for androgenic alopecia.

In this study on mice, a baricitinib-loaded microneedle patch enhanced hair growth in alopecia areata lesions (68% vs control: 33%, p < 0.05), suggesting it may deliver treatment effectively and pain-free, with fewer systemic side effects.
