May 2003 in “Development” The study demonstrated that Myc activation in mouse epidermis led to the depletion of the epidermal stem cell compartment by altering adhesive interactions with the local microenvironment. This was evidenced by the transcriptional analysis of over 10,000 genes, revealing that Myc activation induced genes related to RNA and protein synthesis, cell proliferation, and differentiation, while downregulating over 40% of genes associated with cell adhesion and cytoskeleton proteins. These changes impaired keratinocyte adhesion, motility, and wound healing, correlating with decreased expression of extracellular matrix proteins and integrins, and reduced formation of hemidesmosomes and actomyosin cytoskeleton assembly. Consequently, Myc activation prompted stem cell exit and differentiation into sebocytes and interfollicular epidermis at the expense of hair lineages, due to impaired keratinocyte migration necessary for hair differentiation.

April 2012 in “Cancer Research” The study used transgenic mice to investigate the role of MEK and Antizyme (AZ) in skin tumorigenesis and keratinocyte differentiation. Mice overexpressing MEK showed increased epidermal stem cell expansion and decreased keratinocyte differentiation, leading to epidermal hyperplasia and tumor development. However, co-expression of AZ reduced tumor development by decreasing ornithine decarboxylase (ODC) activity, which is linked to polyamine biosynthesis and tumor promotion. AZ expression counteracted MEK-induced effects, normalizing the number of transient amplifying (TA) cells and stem cells, and restoring differentiation marker levels in keratinocytes. The findings suggested that ODC and polyamines were crucial in regulating epidermal stem cell behavior and keratinocyte differentiation.

June 2013 in “The Journal of Pathology” The study on lichen planopilaris (LPP) involved 42 adult patients and demonstrated that the disease was characterized by the collapse of immune privilege in the hair follicle's epithelial stem cell niche, specifically in the bulge area. This collapse was marked by increased expression of MHC class I and II molecules and a reduction in TGFβ2 and CD200 expression, leading to a Th1-biased cytotoxic T cell response. The findings suggested that interferon-γ (IFNγ) played a significant role in this process, indicating that LPP might be an autoimmune disease. The study proposed that protecting or restoring immune privilege in the bulge could be a therapeutic strategy for managing this form of cicatricial alopecia.
