This study investigated differences in gene expression in the mammary glands of SLICK and wild-type Holstein cattle, finding limited differences overall but identifying enriched pathways related to arachidonic acid metabolism and oxytocin production, which merit further exploration.

This study found that maintaining a low level of Wnt/β-catenin activity is crucial for mammary gland development, as excessive activity inhibits branching and promotes characteristics of hair follicles instead, highlighting its role in skin appendage identity decisions.

This study found that mTOR gene expression was significantly higher in individuals with acne vulgaris compared to healthy controls, suggesting its potential as a biomarker for acne prognosis and treatment response.

This study reported that mammary stem cells in terminal end buds of the mammary gland primarily contribute to branching morphogenesis through dynamic positional regulation and cellular rearrangement.

This research found that Foxc1 is critical for maintaining quiescence in activated hair follicle stem cells and that the cancer cell-of-origin influences tumor heterogeneity in mouse skin squamous cell carcinoma.

This study observed very high thallium levels in small mammals near a zinc smelter in Poland, accompanied by severe population and health impacts.

mTORC2 is crucial for healthy skin barrier by regulating lipids and filaggrin.

In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study found evidence that polythelia pilosa, previously excluded from classification, should be reintroduced as it marks true aberrant mammary structures in men and hirsute women.

This article explores the structure of mammal body hair and the challenges in explaining its evolutionary origins, reporting no new empirical findings.

This study found that the mammalian Hr protein can interact with the p53 pathway by binding to a specific p53 response element, influencing the regulation of genes involved in cell cycle control.

This study observed that developing mammary organs in Monodelphis domestica show mammary hairs in 12-week-old females, which disappear by 18 weeks, with findings suggesting shared characteristics between their nipples and eutherian nipples, supporting the evolutionary link between mammary glands and hair organs.

Long-term use of finasteride may cause breast cancer in men.

This review discusses advances in understanding mammalian stem cell niches, particularly in bone marrow, tooth, and hair follicle, and highlights the potential for developing therapies targeting these niches for tissue repair.

This review discusses the role of mTOR kinase in pulmonary fibrosis and explores how mTOR inhibitors may help slow the progression of this condition, but it reports no new results.

This study found that the retinoid LGD1069 suppressed mammary tumorigenesis in a mouse model without observable toxicity, while TTNPB showed modest effects but was associated with significant toxicity.

This review explores the structural and functional sex differences in mammals beyond reproductive organs, highlighting variations in life expectancy, organ size, metabolism, and immune function, but it reports no new results.

This review discusses mammalian models of epimorphic regeneration to define a vertebrate regeneration blastema, concluding that regenerative failure likely stems from cellular responses to the microenvironment after injury, not progenitor cell availability, and calls for targeted modification studies in mammals to advance human regeneration.

This review examines the neuroendocrine mechanisms underlying seasonal changes in mammals and highlights areas needing further research, reporting no new experimental results.

This review explores embryonic epidermal development and discusses key molecular regulators and roles of the sub-epidermal mesenchyme, but reports no new experimental results.

In this study, researchers demonstrated that in a mouse model, the stimulation of mammary tumor growth due to progesterone is primarily caused by its metabolite, 5αP, not progesterone itself.

This review highlights the possibility of safely altering hair color through innovative cosmetics by targeting key biological processes in hair follicles, using insights from mammalian pigmentation studies and drug-induced hair color changes as potential pathways.

This study found that mammary resident macrophages play a key role in mammary tissue development by influencing cell division and maintaining mammary stem cell activity through the TNF-α-Cdk1/Cyclin B1 signaling pathway, highlighting their importance in the mammary stem cell niche.

This study introduced the concept of spatiotemporal clocks to understand how different phases of mammalian wound healing are coordinated, with a focus on the spatial domains and oscillatory molecular signals involved, while highlighting the potential for regenerative therapeutic strategies.

In this review, the potential role of the hormone prolactin in skin biology and its implications for treating skin diseases and hair disorders are explored, with a focus on its stress-related impacts and possible immunomodulatory function in the context of COVID-19.

This paper provides a comprehensive review of melanocytes' roles in skin biology, focusing on their pigmentation and immune functions, and suggests potential research opportunities for preventing and treating skin disorders.

This study detailed the developmental stages of the buffalo mammary gland during prenatal growth, identifying key morphological features at various gestation lengths.

This discussion highlights inflammation's potential role in hair loss symptoms like androgenic alopecia but reports no new research findings.

This study found that overexpression of NSD3 in the mammary gland of transgenic mice led to mammary hyperplasia, dysplasia, and invasive ductal carcinoma, mirroring patterns seen in human breast cancer.
