This study found that applying topical thymidine dinucleotide (pTT) to newborn mice before UV exposure delayed and reduced melanoma development compared to untreated controls.

This study found that aged tritiated thymidine breaks down and incorporates into cytoplasmic macromolecules, not DNA, suggesting caution in its use.

In this study, insulin-like growth factor-1 did not impact hair follicle elongation in rat pelage hair follicles, while transforming growth factor-beta 1 inhibited both elongation and thymidine uptake.

This study identified histologic lesions and a defect in adhesion molecules causing hair loss in mice with the bal mutation, linked to a mutation in the desmoglein 3 gene.

This study observed that applying polyamines to the skin of hairless mice stimulates thymidine incorporation, suggesting polyamines may play a role in DNA synthesis control in the epidermis.

This study found that areola formation in mice requires a combination of pregnancy hormones and mechanical strain, with individual stimuli causing only modest changes in epidermal proliferation and connective tissue remodeling.

This study investigated the use of spironolactone in patients with estrogen-dependent cancers, aiming to determine if it is linked to increased cancer recurrence risk, but results are not reported.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

Minoxidil slows fibroblast growth and collagen production, potentially treating keloids, hypertrophic scars, and connective tissue disorders.

The new system can grow hair in the lab and test hair growth treatments.

This article reviews a new method to accurately estimate proliferative and migratory epithelial cell numbers post-wounding but reports no experimental findings; the authors suggest its relevance to skin stem-cell biology research.

This study examined the role of biotin deficiency and adequacy on cell proliferation and DNA synthesis in isolated mohair follicles.

This study investigated the effects of biotin deficiency and adequacy on cell proliferation and DNA synthesis in isolated mohair follicles, particularly focusing on the incorporation of [methyl-3 H]thymidine.

This study found that keratin 19 may be a marker for skin stem cells, helping to characterize these cells in different conditions and potentially explaining variations in healing rates between children and adults.

This study found that melatonin's effect on HaCaT keratinocyte proliferation varied with concentration and incubation time, with no cytotoxic effects observed at suitable concentrations for skin treatment.

This study identified a novel mutation in the coproporphyrinogen oxidase gene, contributing to hereditary coproporphyria in a family, with decreased enzyme activity observed in the affected members.

This review discusses techniques for analyzing the cell cycle, highlighting emerging tools for measuring cell cycle speed at single-cell resolution in live animals, and reports no new results.

In this study, high concentrations of dihydrotestosterone and testosterone reduced the growth of human hair follicle cells in vitro, while high estradiol levels increased their growth.

This review discusses the current state of early diagnosis and targeted therapy for gastric cancer, emphasizing the benefits of minimally invasive surgical approaches and suggesting future advancements may improve prevention and treatment without major lifestyle changes.

The European School of Oncology organized various educational events in 1994, highlighting important cancer research findings.

In this study, silver oxide-based nanoparticles were used to ionize analytes and detect specific target molecules through adduct formation with silver isotopes, facilitating signal correlation with these molecules.

This study found that loss of the DNA methyltransferase Dnmt3a, but not Dnmt3b, increased carcinogen-induced squamous tumors in murine epidermis, with combined deletion leading to more aggressive and metastatic carcinomas.

The research found that while Dnmt3a and Dnmt3b are not necessary for skin homeostasis in mice, the loss of Dnmt3a increases squamous tumor formation from carcinogens, and combined deletion of both results in more aggressive and metastatic tumors.

This study observed morphological changes in scalp hair follicles of humans deprived of protein for 15 days, which suggests potential use in diagnosing protein-calorie malnutrition.

This study found that topical finasteride and flutamide both significantly reduced sebaceous gland growth and decreased prostatic weights in hamsters, indicating systemic effects despite local application.

This study found that hair follicle cells' growth in vitro is influenced by the concentration of androgens and antiandrogens, with papilla cells and outer root sheath keratinocytes showing distinct sensitivity.

This study found that bisindolylmaleimide PKC inhibitors increased DNA synthesis in mouse hair follicles, suggesting that PKC may inhibit hair follicle proliferation.

This study found that the androgen precursors DHEA and androstenedione stimulated androgen-sensitive parameters in the sebaceous glands of the skin in castrated male hamsters.

This review discusses the various dermatological applications of zinc, including its use in treating infections, inflammatory dermatoses, pigmentary disorders, and neoplasias, and reports no new clinical findings.

This review discusses the distinct roles and surprising developmental flexibility of multiple somatic stem cell types in tissue maintenance and repair, reporting no new results but highlighting emerging questions about their regulation and origins.
