Understanding where cancer cells come from helps create better prevention and treatment methods.

This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

This study found that transgenic mice expressing human keratin K8 in the epidermis showed increased progression of skin lesions toward malignancy, suggesting a role for K8 in the development of invasive skin cancer.

This workshop review discusses the dual role of cellular senescence in cancer, highlighting both its anticancer effects and pro-tumorigenic potential, while reporting no new research results.

This study suggests that PDCD4 regulates keratinocyte proliferation and contact inhibition, playing a role in epidermal homeostasis and wound healing.

Active oxygen species might be involved in skin tumor growth, but their exact role is unclear.

This study found no correlation between clinical signs and sex steroid levels in ferrets with hyperadrenocorticism and noted that androstenedione was elevated in many cases.

This study found that skin adnexal tumors are mostly benign, with 98.6% of cases being non-cancerous, and highlighted histopathological examination as essential for accurate diagnosis and management, given their frequent clinical misdiagnosis.

This study describes a functional disorder in the ovary, known as stromal hyperplasia, characterized by the proliferation of ovarian stroma and luteinization of stromal cells, which is linked to excessive androgen production and elevated testosterone levels.

Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.

Hair transplantation effectively treated a bald patch in an 18-year-old woman with Temporal Triangular Alopecia.

Testosterone and dihydrotestosterone affect hair growth, and new techniques like the folliculogram help study it, but fully understanding hair growth is still complex.

This study describes a case where finasteride treatment for benign prostatic hypertrophy was associated with gynecomastia in a 62-year-old man, which resolved after the drug was discontinued.

In this study, topical application of α-methylspermidine during the telogen phase in mice induced hair growth by increasing the polyamine pool and mimicking the anagen phase's characteristics.

This study reported that new drugs, despite lower specificity compared to certain immunobiological therapies, are effective across various challenging dermatological diseases, such as psoriasis, psoriatic arthritis, atopic dermatitis, alopecia areata, and vitiligo.

This study found that VEGF-deficient keratinocytes can form tumors using different aneuploidy and signaling patterns, highlighting VEGF's role beyond angiogenesis in tumor cell growth and survival.

This review summarizes current evidence on the use of contact immunotherapy, excluding alopecia areata, for various skin diseases, discussing its safety, efficacy, and the underlying mechanisms as reported from studies in the PubMed database.

Collagen VII helps skin heal and stay strong, sirolimus may lower skin cancer risk in kidney transplant patients, high-molecular-mass hyaluronan helps naked mole rats resist cancer, dermal γδ T cells aid in hair growth in rodents, and overexpression of IL-33 in mouse skin causes itchiness, offering a model for studying allergic inflammation treatments.

Treatments for acute leukaemia lead to high remission rates, but relapses occur, requiring ongoing advancements in care.

This systematic review suggests that turmeric and curcumin products, both oral and topical, may offer therapeutic benefits for various skin conditions, though further research is necessary to evaluate efficacy more thoroughly.

This article reviews the potential of combining antiandrogenic and antiestrogenic treatments for BPH, highlighting aromatase inhibitors, but presents no new clinical results; further research is needed.

In this study, transplanted hair follicles from different body sites showed changes in morphology and immune status, suggesting their ability to adapt and function in new recipient areas such as the scalp or eyebrows.

This study presents a detailed overview of lymphatic vessel development and highlights the role of abnormal lymphangiogenesis in various diseases, suggesting that targeting lymphangiogenic factors may improve treatment strategies.

This study found that reflexology massage significantly improved hair regrowth in women with chemotherapy-induced alopecia compared to those receiving usual care.

In this animal study, the researchers found that DPP4 plays a crucial role in scar formation and wound-induced hair follicle neogenesis in mice, impacting regenerative repair.

This study found that the protein p63 requires morphogenetic signals to regulate gene expression effectively during skin cell differentiation, highlighting its complex role in therapeutic reprogramming for conditions like epidermolysis bullosa.

This research outlines how retinoids, compounds based on vitamin A, activate nuclear receptors to influence cellular processes such as differentiation and carcinogenesis, with benefits like anti-inflammatory properties but requiring careful management of dose-dependent side effects.

Oral retinoids are effective for severe skin conditions but require careful use due to side effects.

This article suggests that imaging abnormalities in intestinal stem cell compartments could potentially be incorporated into colorectal cancer screening, but provides no new clinical results.
