This article discusses the classification of mental retardation based on IQ ranges and provides no new experimental findings.

This study used a probabilistic Boolean network model to explore hair follicle cell fate regulation and predicted that varying TGF-β levels, in coordination with BMP and TNF, can influence either apoptosis or cell proliferation during different follicle growth stages.

This study found that inactivating CerS4 in mice led to hair follicle stem cell exhaustion and hair loss, indicating its role in regulating hair regeneration through ceramide composition and signaling pathways.

In this study, the researchers analyzed skin samples from Dun Mongolian horses to uncover molecular pathways linked to the "Bider" marking, identifying differential gene expression and several pigment-related signaling pathways that may play key roles in its formation.

This animal study observed that while topical MBEH and intraperitoneal phenol induced hair graying in eumelanic mice, they had little effect on pheomelanic mice, and amcinonide reduced certain epidermal melanocytes in both.

In this study, Msx2-deficient mice showed progressive hair loss due to shortened anagen phase and prolonged catagen and telogen phases, resulting in cyclic alopecia with structurally abnormal hair shafts.

This study introduces a co-design framework using finite element analysis to optimize separable bubble microneedles, demonstrating enhanced transdermal and sublingual drug delivery in preclinical models. In vivo results showed faster hair regrowth and glucose lowering in animals, indicating potential improvements over traditional methods.

This study found that inhibiting the enzyme ornithine decarboxylase (ODC) prevented UVB-induced basal cell carcinomas in a mouse model, suggesting ODC is a potential target for chemoprevention strategies.

This study found that stem cells derived from spinal and bulbar muscular atrophy patients exhibited reduced androgen receptor levels and HDAC6, providing potential insights into the disease mechanism for future therapies.

This review examines PAK4 signaling pathways in prostate cancer, Parkinson's disease, and melanogenesis, focusing on the potential role of the PAK4-CREB axis, without reporting new clinical results.

This case report discusses the diagnostic challenges and management options for three siblings with 46, XY DSD due to type 2 5-α reductase deficiency, highlighting the genetic basis and impact on their quality of life.

This study found that overexpression of neurotrophin 4 in mouse skin increased hair follicle and Meissner corpuscle innervation without altering sensory neuron numbers, differing from brain-derived neurotrophic factor by not affecting Merkel cell numbers.

This study found that A(3)B(5) downregulates melanin production and suppresses melanoma cell growth by promoting proteasomal degradation of TRP-2.

This study found that finite element analysis-guided design improved bubble microneedles' controlled tip separation and insertion strength, supporting effective transdermal and sublingual drug delivery.

This study found that mrp/plf-mRNA expression in murine skin increases in response to different tumor promoters, suggesting its potential as a short-term biomarker for chemical carcinogenesis.

This study found that deleting the Mad2l1 gene in mice leads to rapid onset of acute lymphoblastic leukemia and liver cancer due to induced chromosomal instability.

This study found that the BIK1 gene in Arabidopsis thaliana modulates defense responses to pathogens and is essential for normal root growth and development.

In this study, deleting the gene Mettl3 in mouse epidermal progenitors resulted in impaired epithelial development and self-renewal, highlighting m⁶A's crucial role in regulating chromatin modifiers and maintaining normal epithelial tissue function.

This study found that immune-mediated destruction of bulge stem cells is a key factor in the alopecia observed in AE mice, suggesting it as a model for studying primary cicatricial alopecias, particularly lichen planopilaris.

This study found that the K6/ODC transgenic mouse model is highly sensitive to identifying genotoxic carcinogens, showing 100% concordance with traditional rodent bioassays.

This paper reviews the role of ATP-dependent chromatin remodeling complexes in epidermal homeostasis, hair regeneration, and skin repair, noting contributions to 3D-genomic organization and suppression of UV-induced hyper-proliferation, without presenting new results.

In this study, the researchers found that thymosin beta-4 promotes odontoblastic differentiation in human dental pulp cells, suggesting it as a potential mechanism for regenerative endodontics.

This study found that mycophenolate may stabilize β-catenin and counteract interferon-γ-induced catagen changes in human dermal papilla cells, which could promote hair growth.

This commentary discusses how common latent viruses might contribute to male-pattern baldness through mechanisms involving transcription factor deficiency and overexpression of specific proteins, based on a concept called microcompetition; it reports no new research results.

This study reports that the loss of the protein Memo in mice leads to a reduced lifespan and suggests that Memo is a key regulator of FGFR signaling and vitamin D production.

This study reported that rice bran oil from the Thai rice variety BB4CMU showed potential in promoting melanin production and inhibiting steroid 5α-reductase, suggesting a natural option for hair revitalization.

This report detailed the British Hair and Nail Society's national grand round, which aids in diagnosing and treating complex hair disorders, showcasing rare diagnoses and suggesting novel therapies.

This study found that Minoxidil included in triamino alpha-cyclodextrin significantly promoted hair growth in mice, potentially due to its enhanced substantivity on skin.

This study found that during amelogenesis in Msx2 null mice, a dysfunctional enamel organ developed due to abnormal epithelial transformation and lacked proper enamel formation.

This study demonstrated that a combination of four types of honey significantly improved hair integrity, porosity, and surface roughness after exposure to UV-A and pollution stress.
