This review discusses the characteristics, potential genetic components, and treatment options for trichotillomania, a psychiatric condition that involves compulsive hair pulling, without reporting new clinical results.

In this case-control study, researchers did not find genome-wide significant genetic variants for trichotillomania, but cases had higher polygenic risk for psychiatric disorders and certain neuropsychiatric-associated copy number variants.

This review highlights that obsessive-compulsive disorder and body-focused repetitive behaviors are increasingly encountered in dermatology, often going undetected, and emphasizes the role of dermatologists in early identification and interdisciplinary treatment to address both physical and psychological aspects for improved outcomes.

This study found that sinapic acid promotes the browning of 3T3-L1 adipocytes and may offer therapeutic potential for obesity by influencing mitochondrial biogenesis through the p38 MAPK/CREB signaling pathway.

In this clinical trial, the topical agent AP-FHG0604T significantly increased hair counts and growth rates in women with female pattern hair loss compared to a placebo, though some reported mild local irritation.

This study suggests that KRTAP2-3 may serve as a novel biomarker to identify cells in the polyaneuploid cancer cell state, which is linked to therapy resistance and poor prognosis in prostate cancer.

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 study suggests that sinapic acid may promote hair growth in human hair follicle dermal papilla cells by activating specific signaling pathways and inducing the expression of growth factors.

In this study, researchers identified two new keratin-associated proteins, hKAP1.6 and hKAP1.7, in human hair follicles, contributing to understanding hair fiber differentiation.

Caspase-3 helps control cell growth and organ size by activating YAP.

This case report describes an 87-year-old woman diagnosed with type 3 autoimmune polyendocrine syndrome, highlighting the importance of recognizing and managing coexisting autoimmune conditions.

In this study, researchers used scanning electron microscopy to analyze hair damage from 3% hydrogen peroxide and UVB radiation, observing that Caesalpinia sappan hair tonic formulations coated and interacted with the hair cuticle, potentially modifying hair fiber damage.

This article proposes an updated naming system for keratin-associated proteins and genes, aiming to improve data storage and retrieval by including species information and genetic variation.

In this study, gel containing apigenin and celery herb extract was observed to effectively stimulate hair growth and did not cause skin irritation in male Sprague-Dawley rats.

This study identified numerous size polymorphisms in the human ultrahigh sulfur KAP4 genes due to intragenic sequence variations, suggesting these polymorphisms may have arisen through deletions and duplications during evolution.

This study identified 16 novel high sulfur KAP genes and two KAP pseudogenes on chromosome 21q23, showing expression in a specific region of the hair fiber cuticle.

In this study, researchers identified five unique sequences of the ovine KAP13-3 gene, with potential implications for wool traits due to observed amino acid changes.

This study found that inhibiting AP-1 activity in mice can induce lineage transdifferentiation between squamous and sebaceous tumors, suggesting AP-1's role in maintaining tumor cell identity.

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 successfully synthesized acetyl tetrapeptide-3 on a laboratory scale with over 56% yield and 100% purity, supporting its use in developing hair loss and scalp care products.

This study found that a powder made from papaya seeds and celery leaves remained stable for 3 weeks when stored at room or cold temperatures, suggesting potential for hair health applications.

This study identified a new compound from fermented Carica papaya L. with moderate antioxidant and potent hair growth-stimulating activities in vitro.

This study analyzed the ethanol extract of pacing tawar leaves and found it contains alkaloids, saponins, tannins, and steroids but not flavonoids, suggesting potential for use in natural medicinal products.

This study identified a compound heterozygous mutation in a hairless rhesus macaque, which was associated with skin abnormalities similar to those in hairless mice and humans with APL.

In this study, researchers identified a cluster of hair-specific keratin-associated protein genes within the 21q22.3 region, revealing a novel transcription mechanism involving TSPEAR/C21orf29 that may bypass typical transcriptional termination sites.

This report describes a Sapajus nigritus investigated for multiparasitism after rescue from illegal home possession, highlighting public health and biodiversity conservation concerns related to human-primate proximity.

This study found that 3-Deoxysappanchalcone may stimulate hair growth in mice by promoting proliferation of hair follicle dermal papilla cells through WNT/β-catenin and STAT signaling modulation.

This study found that inhibiting AP-1 activity in mice modified tumor development, leading to transdifferentiation between squamous and sebaceous tumors, with molecular analysis suggesting AP-1's role in maintaining tumor cell identity.

This study identified two novel genes, pmg-1 and pmg-2, expressed in various skin and gland tissues and potentially involved in the differentiation of epithelial cells in epidermal appendages.
