This study concluded that hair follicle hyperplasia found in pseudolymphomatous folliculitis can also occur in genuine cutaneous lymphomas, potentially as a coincidental result of underlying pathological processes.

This study found that finasteride treatment decreased VEGF expression in the prostate tissue of patients with benign prostatic hyperplasia, although it did not affect vascular density or serum VEGF levels.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This study found that L-type channel blockers can induce hair growth in Timothy syndrome by overcoming delays in anagen phase, suggesting a potential therapeutic role for tissue regeneration.

This study found that the protein CCN2 in dermal papilla cells is a physiologically relevant suppressor of hair follicle formation by destabilizing β-catenin, which may help maintain stem cell quiescence.

This study found that finasteride decreased DHT-stimulated AR activity and cell growth in prostate cancer cells with mutant AR, but not in those with wild type AR.

This study reports that PDRN, commonly used for wound healing, may also have anti-melanogenesis and potential skin whitening effects in both experimental models and clinical settings.

This study demonstrates that keratinocyte cell lines derived from cultured hair follicles can fully differentiate in organotypic skin models, offering a minimally invasive alternative to obtaining keratinocytes for research.

This study reported that Indian hedgehog (Ihh) signaling plays a crucial role in regulating tumor progression and metastasis in epithelial cancers, with Ihh deficiency leading to increased malignancy and metastasis in mice.

In this study, activation of oncogenic K-ras in a mouse model caused the oral mucosa to rapidly progress from squamous hyperplasia to carcinoma within 14 days, demonstrating its acute sensitivity.

This study describes a method for labeling and tracking hair follicle stem cells in mouse skin using a Cre/lox recombination system with tamoxifen, providing insights into stem cell behavior and contribution to tissue regeneration.

In this study, PKC ε transgenic mice exposed to ultraviolet radiation showed increased hair follicle stem cell frequency and altered gene expression compared to wild-type mice, suggesting a potential role in skin cancer susceptibility.

This study found that COX-2 expression in normal rat skin is linked to the hair cycle, with varying levels observed in different skin structures during anagen, catagen, and telogen phases.

This study observed that both Factor XIIIa+ dermal dendrocytes and microvasculature size decreased with scalp aging and that alopecia changes resembled stress-induced premature senescence.

This review summarizes the characteristics of the peri-malignant melanoma stroma, indicating its potential role in early dermal metastatic migration and increased metastasis risk.

This study found that nestin-negative hair follicle stem cells can differentiate into neural stem cell-like cells, but not mature neurons, through a multi-step neuro-induction process.

This study found that TPA induces apoptosis in pig renal epithelial cells by affecting cell cycle proteins, and activated ras can prevent this process.

This study found that implanting hair-follicle-associated pluripotent stem cell sheets facilitated wound healing and early macrophage activity while reducing inflammation in a diabetic mouse model, suggesting clinical potential for difficult-to-heal diabetic ulcers.

This study found that in hairpoor mice, disruptions in hair follicle stem cell quiescence and signaling pathways lead to disturbed hair cycles, which may help explain alopecia development in Marie-Unna Hypotrichosis patients.

This study found that maternal caffeine intake during gestation and lactation can lead to skin lesions like hypotrichosis and alopecia in both mother and offspring rats, irrespective of maternal cortisol levels.

The study found that CK15 expression, representing hair follicle stem cell activity, was reduced or absent in scarred primary cicatricial alopecia lesions, suggesting stem cell damage may contribute to the scarring process.

This study suggests that follicular stem cells in the bulge region are not directly targeted in androgenetic alopecia, based on the consistent presence of cytokeratin 15 across scalp samples from affected patients.

The researchers suggest that combining microneedle technology with nanocarriers could enhance drug delivery systems for treating central neurological diseases due to nanoparticles' ability to prolong blood circulation time and improve brain targeting.

This study identified novel genetic variants in APOE ε4 non-carriers associated with Alzheimer's disease age-of-onset, linking them to regulatory mechanisms like the unfolded protein response in the pathology of Alzheimer's and other degenerative diseases.

This study examined older adults undergoing chemotherapy and found that nutritional-inflammatory biomarker ratios were significantly linked to cognitive impairments, treatment side effects, and quality of life indicators, suggesting these lab measurements might help identify high-risk individuals for intervention.

This case report describes a patient with adrenomyeloneuropathy, highlighting unusual MRI findings of high signal areas in the right striatum.

This study reported that machine learning analysis of protein profiles in hair segments achieved high accuracy in distinguishing women with non-suicidal self-injury disorder from healthy controls, suggesting hair proteomics as a promising non-invasive biomarker for stress-related psychopathology with potential clinical applications.

This study investigated NNAT expression in embryonic and postnatal rat tissues, finding its localization in both undifferentiated and differentiated cells across tissues such as the pancreas, tongue, and testis.

This study developed a two-step diagnostic model using transcriptome biomarkers from hair follicles to improve the accuracy of methamphetamine use disorder diagnosis, achieving high prediction accuracy in distinguishing non-recovered and almost-recovered patients from healthy controls.
