This paper reports that noggin inhibits BMP-2 and BMP-4 functions by binding and blocking their interaction with the BMP receptor, impacting multiple developmental processes without presenting new research results.

This review summarizes existing reports on placenta extract for treating liver injury and discusses its mechanisms but provides no new clinical results.

This study found that loss of the ACER1 gene in mice led to increased ceramide levels and progressive hair loss, highlighting ACER1's role in maintaining hair follicle stem cell homeostasis.

Mechanical stretching can improve or hinder skin regeneration depending on duration.

This review discusses recent in vitro and in vivo research suggesting that components of ginseng, such as ginsenosides and gintonin, may have potential skincare benefits, including anti-aging effects and treatment of skin conditions like atopic dermatitis and hypertrophic scars.

This study found that elevated epidermal ODC activity in transgenic mice promotes skin tumor development by recruiting bulge stem cells, rather than through reactive oxygen species generation by polyamine catabolic oxidases.

Mutations in β1 integrins cause embryonic death but have milder effects on skin.

This study found that normal human melanocytes can be protected from apoptosis through both PI 3-kinase/Akt-dependent and independent pathways, with insulin and TPA offering nearly complete protection.

This review highlights the role of the receptor TLR4 in cellular aging and age-related diseases, suggesting it as a potential therapeutic target due to its contribution to persistent inflammation and symptom regulation in these conditions.

This study identifies KLK14 as a significant factor contributing to hair defects and skin inflammation in a mouse model of Netherton syndrome.

This study observed that transgenic mice expressing keratin K10 under bovine K6beta control developed severe oral abnormalities, suggesting keratin composition changes can affect the physiology of epithelial cells, especially in the oral mucosa.

In this study, researchers found that basal cell carcinomas with common Hedgehog signaling mutations may require additional mutations to hyperactivate downstream signaling and progress beyond dormancy.

This study found that BNC2 is critical for hair follicle regeneration and other developmental processes, as Bnc2−/− mice exhibit incomplete hair follicle development and developmental defects, and BNC1 cannot substitute for BNC2.

This study found that in mice, low-dose irradiation causes stem cells in hair follicles to undergo chromatin alterations, which may eventually lead to long-term functional loss in tissues or organs.

This review discusses the role of telomere length dynamics in hair follicle biology and reports no new clinical findings, emphasizing the need for further research in humans.

This study found that ISX9 may activate the Wnt/β-catenin signaling pathway and holds potential as a therapeutic agent for treating alopecia.

This study suggests that distinct chromatin topologies allow different lineage-specific enhancers to regulate Hoxd genes in mouse vibrissae and chicken feather primordia, while conserved regulatory elements maintain transcriptional robustness in the embryonic trunk across species.

This review evaluates the potential of natural products and medicinal plants for myocardial infarction treatment, highlighting their therapeutic promise and mechanisms such as reducing oxidative stress and inflammation, but reports no new clinical results.

This study found that hair follicles play a significant role in regulating skin barrier function, with disruptions in the upper hair follicle affecting the epidermis, influencing processes like desquamation and sebum release, and leading to cell movement into the epidermis.

This study found that PBX1 overexpression reduces hair follicle-derived mesenchymal stem cell senescence and apoptosis by alleviating ROS-mediated DNA damage, rather than enhancing DNA repair.

This study found that LEF-1 expression influences dermal papilla cells' proliferation through Wnt signaling, impacting the potential for cashmere yield improvement.

This review discusses the role of Wnt signaling in cardiac development and explores attempts to modulate it for improving heart function after ischemic injury, but reports no new experimental results.

This study developed a genetic toolbox to engineer Cutibacterium acnes for dermal applications, successfully creating a strain that secretes antioxidants to reduce oxidative stress in a UV stress model.

In this review, researchers explored how PGC-1α might improve aged skin barrier function by influencing mitochondrial function and reducing inflammation, factors that are linked to epidermal health during aging.

This review explores the potential of self-amplifying RNA technology for protein replacement therapy in various health disorders but reports no new experimental results, indicating challenges remain for clinical approval.

This review discusses the potential of extracellular vesicles for facial aesthetic applications, including scar reduction and skin rejuvenation, but reports no new clinical results; further research into production and mechanisms is needed.

This study reports that actively proliferating Lgr5+ stem cells in hair follicles do not appear to drive tumor formation in experimental skin carcinogenesis.

In this study, researchers found that a subset of mammary cells with active Wnt signaling in mice does not develop tumors upon ErbB2 activation and instead undergoes apoptosis, potentially protecting against carcinogenesis.

This study discusses how redox imbalance, specifically through reduced Insulin-like Growth Factor-1 mediated by the transcription factor JunB and sphingolipid metabolism changes, contributes to skin aging by depleting stem cell pools and altering the extracellular matrix, ultimately impacting skin integrity and function.

This review highlights that current in vitro models often fail to replicate the physiological oxygen levels experienced by different skin cell types, which could affect redox states and functions, potentially accelerating skin aging.
