This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This study observed that hepatocyte adhesion to human hair keratin biomaterials was mediated by the hepatic ASGPR, as blocking this receptor reduced cell attachment.

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.

In this study, researchers found that size polymorphisms in certain hKAP1 genes are linked to the hKAP1.1B and hKAP1.3 genes, arising from intragenic deletions and duplications in Japanese and Caucasian populations.

This article discusses the development and clinical progress of PROTAC technology, particularly focusing on the New Drug Application for vepdegestrant, an estrogen receptor-targeting PROTAC, marking significant advancements in targeted protein degradation therapies.

This study reports that the autotaxin–LPA–LPA3 signaling pathway at the embryo-epithelial boundary plays a critical role in decidualization by up-regulating HB-EGF and COX-2 in the uterine epithelium.

This study discusses the potential association between low vitamin D levels and insulin resistance, suggesting that vitamin D deficiency may contribute to disorders like obesity and diabetes, but emphasizes the need for further research to confirm these links.

This review discusses the negative health impacts of testosterone deficiency and the potential adverse effects of 5α-reductase inhibitors, emphasizing the need for patient-physician discussions regarding these treatments.

This review establishes a tolerable upper intake level of 255 μg/day for selenium in adults, warning that supplements and Brazil nuts may cause excess intake.

This review discusses insulin resistance in women with polycystic ovary syndrome and reports no new clinical results; it highlights the potential benefits of lifestyle changes and insulin-sensitizing drugs.

This study found that liposterolic extracts of Serenoa repens enhanced hair regeneration and repair in DHT-induced hair loss mouse models, suggesting potential effects comparable to finasteride.

This study reported that baicalin activates the Wnt/β-catenin signaling pathway in mouse hair follicles, suggesting its potential as a topical treatment for hair loss.

In this study, the researchers observed that MMP-2 and MMP-9 significantly fluctuated with the hair growth cycle in mice, suggesting their important role in hair development.

This study found that synthetic melanin particles applied topically in mouse injury models improved wound healing, showing potential as a therapy for accelerated healing, including in human skin explants.

This study found that using layer-by-layer encapsulation techniques on dermal papilla cells can support their function and may help treat hair loss when used in conjunction with freshly isolated epidermal cells.

This study found that keratinocyte stem/progenitor cell-conditioned medium significantly enhanced hair growth in mice and increased the proliferation of human hair follicle cells.

This study found that ferulic acid promotes wound healing by inhibiting β-catenin in keratinocytes and activating Nrf2 to reduce inflammation at the wound edge.

This study reported that Panax ginseng extract significantly inhibited DKK-1-induced catagen-like changes in human hair follicles by promoting cell proliferation and reducing apoptosis, suggesting it may help mitigate hair loss associated with DKK-1.

This study found that the humanin analogue HNG significantly promoted hair growth in vitro and in vivo by prolonging the anagen phase and inhibiting hair follicle cell apoptosis in mice.

In this study, rabies virus antigens were detected in the outer root sheath of the follicle-sinus complex in the muzzle skin of rabid dogs, suggesting its usefulness as an alternative diagnostic specimen.

In this study, finasteride was found to enhance stem cell properties in dermal papilla cells, suggesting potential benefits for hair loss management and regenerative therapies.

In this study, around 1% of proteins in skin fibroblasts significantly changed in response to reductive stress, affecting collagens and MAPK signaling pathways.

In this study, researchers found that disrupting EGFR signaling in mice led to increased inflammation and hair follicle damage but that inhibiting the JAK-STAT1 pathway could restore hair growth and skin function.

This study suggests that the herbal formulation Phyllotex™ may promote hair growth in androgenetic alopecia by enhancing cell proliferation and reducing oxidative stress and TGF-β1 expression in vitro.

This review discusses the challenges in diagnosing PCOS in adolescents due to overlapping symptoms with normal puberty and reports no new clinical findings, emphasizing the need for more research on treatment options.

This study found that α-ketoglutarate protected dermal papilla cells from oxidative stress by enhancing the Nrf2 pathway and mitigating cell damage through the ERK/Nrf2 axis.

In this study, voglibose, commonly used for diabetes management, was found to reduce melanin synthesis and inhibit melanogenic signaling pathways in B16F10 melanoma cells, suggesting it could be repurposed for treating hyperpigmentation disorders with confirmed topical safety in human tests.

This study found that low-level laser therapy effectively reduced relapse rates, while functional appliances did not; combining them offered no additional benefits.

This study reports that some human cell surface HLA-I molecules (including HLA-B27) can appear without their usual peptide component, potentially altering immune interactions, influencing arthritis development in specific mice models, and exhibiting upregulation in certain cancer cells.

This review discusses recent advances in the treatment of alopecia areata, highlighting new potential therapies like JAK inhibitors and PRP, and reports no new clinical results.
