420-450 / 491 results research Keratin-6 driven ODC expression to hair follicle keratinocytes enhances stemness and tumorigenesis by negatively regulating Notch
The study investigated the role of ornithine decarboxylase (ODC) in skin carcinogenesis by using genetically modified mice to direct ODC expression to specific epidermal compartments. It was found that K6-driven ODC over-expression in the outer root sheath of hair follicles significantly increased tumorigenesis compared to K14-driven ODC expression in inter-follicular epidermal keratinocytes. Mice with K6-ODC expression developed an average of 15 tumors per mouse, while K14-ODC mice developed 6.8 tumors per mouse. The K6-ODC mice also showed higher UVB-induced proliferation, pro-inflammatory responses, and a greater number of stem-like cells, with reduced Notch1 expression linked to stem cell expansion. The study concluded that ODC enhances tumorigenesis by negatively regulating the Notch pathway, leading to an expansion of the stem cell compartment.

research Alkaline Ceramidase 1 Protects Mice from Premature Hair Loss by Maintaining the Homeostasis of Hair Follicle Stem Cells
The study demonstrated that the alkaline ceramidase 1 (ACER1) gene was crucial for maintaining the homeostasis of hair follicle stem cells (HFSCs) in mice by regulating ceramide metabolism. Mice deficient in the Acer1 gene exhibited elevated levels of ceramides and sphingoid bases, leading to progressive hair loss. The loss of Acer1 resulted in a widened follicular infundibulum and a reduction in HFSC survival and stemness. These findings suggested that ACER1 was essential for preserving the structure and function of hair follicles by controlling ceramide metabolism in the epidermis.

research Stem Cell Heterogeneity and Plasticity in Epithelia
Different types of stem cells exist within individual skin layers, and they can adapt to damage, transplantation, or tumor growth. These cells are regulated by their environment and genetic factors. Tumor growth is driven by expanding, genetically altered cells, not long-lived mutant stem cells. There's evidence of cancer stem cells in skin tumors. Other cells, bacteria, and genetic factors help maintain balance and contribute to disease progression. A method for growing mini organs from single cells has been developed.
