This review examines the origins and mechanisms of tumor initiation in common skin cancers, but does not present new experimental findings; it emphasizes the need for further research on cancer stem cells.

This review explores various theories of colorectal cancer stem cell biology and highlights the need for better identification and targeting of these cells to advance treatment strategies, but reports no new clinical findings.

This review summarizes existing knowledge on androgen receptor activity in breast cancer and reports no new clinical findings, with emphasis on therapies targeting androgen signaling in specific BC subtypes.

This study found that loss of the Pten gene in Lgr5+ hair follicle stem cells promoted squamous cell carcinoma formation through the Akt/β-catenin signaling pathway.

This article discusses the challenges in differentiating between basaloid follicular hamartoma and infundibulocytic basal cell carcinoma, highlighting the need for clarity in diagnosis but reports no new results.

Targeted therapies for lung cancer are effective but require careful management of side effects to benefit patients.

The debate focuses on the role of catagen and hair shedding mechanisms in telogen effluvium.

This study highlighted Keratin 17's critical role in cancer therapy resistance across several malignancies, involving various signaling pathways, and identified it as a significant biomarker and potential therapeutic target, particularly in reversing resistance.

In this study on adult-onset, whole body Spry1/2/4 triple knockout mice, researchers observed endocrine abnormalities and no increased tumor incidence, despite similar food intake and motor function.

The book is a valuable reference on androgenic disorders for professionals but not suitable for laypeople or medical students.

This article critiques the limited clinical applicability of recognizing catagen in hair cycle studies, emphasizing its importance in histologic diagnosis and the continuum with telogen effluvium.

This study found that cucurbitacin I from bitter melon most effectively inhibited the growth of lung cancer cells and promoted hair cell growth in cell cultures.

Some people with primary cicatricial alopecia also have inflammatory bowel disease, suggesting a possible connection.

This study suggests that phenotypic plasticity, including processes like dedifferentiation and transdifferentiation, plays a crucial role in cancer initiation, progression, and therapy resistance, broadening our understanding of cancer dynamics and potential treatment strategies.

This study found that induced expression of mir-302 can reprogram human hair follicle cells into induced pluripotent stem cells through a novel epigenetic mechanism involving global demethylation.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This review discusses the WNT signaling pathway's involvement in human diseases and highlights recent advances in WNT-related treatments, but it presents no new research findings.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This study shows that BMP2 and BMP7 play complex, necessary roles in feather development by regulating dermal condensation formation, with BMP7 acting early as a chemoattractant and BMP2 halting cell migration.

This study found that quiescence in hair follicle stem cells acts as a tumor suppression mechanism for cutaneous squamous cell carcinoma, with Pten activity necessary to maintain this state.

The p53 protein has complex, sometimes contradictory functions, including tumor suppression and promoting cell survival.

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 review discusses the role of tumor suppressors in controlling tumor-associated inflammation and suggests that targeting this inflammation may counteract the effects of tumor suppressor loss.

This study found that nobiletin-loaded vesicles effectively restored skin condition in a mouse model of skin cancer, suggesting they are a promising treatment delivery system.

This review discusses the structure, expression, regulation, and potential roles of NcoA4 in cancer and other pathologies, reporting no new experimental findings.

This review discusses the role of the androgen receptor in breast cancer diagnosis and treatment, and notes a lack of new research results on its therapeutic potential.

The authors suggest that nanoparticles, synthesized from biological sources, may enable targeted cancer therapy with fewer side effects than traditional methods.

This review discusses various applications of CRISPR-based tools in cancer research, emphasizing their potential for investigating microRNA functions and developing microRNA-based therapies, despite challenges like off-target effects and delivery issues in using CRISPR/Cas9.

This study found that the expression of LRIG1 in Merkel cell carcinoma tumors was associated with improved overall and cancer-specific survival.

In this study, researchers developed a new photoactivatable Cre recombinase mouse model, DiLiCre, which allows precise light-induced genetic modifications and cell tracing, demonstrating its effectiveness for advancing biological and biomedical research.
