,
September 2007 in “Wound repair and regeneration” This study found that in vivo bioluminescence can track Smad2/3-dependent TGF-β signaling during the wound healing process in mice, with signaling increasing after healing rather than immediately post-wounding.
25 citations
,
June 2017 in “Journal of Investigative Dermatology” This study found that in a transgenic mouse model, β-HPV infection led to increased skin thickness and proliferation of specific keratinocyte stem cells, which may contribute to squamous cell carcinoma development.

July 1997 in “PubMed” In this study, targeting ornithine decarboxylase overexpression to hair follicle keratinocytes in mice was sufficient to promote skin tumor development without additional tumor promoters.
20 citations
,
April 2000 in “Experimental dermatology” This study observed that overexpression of the enzyme ODC in transgenic mice caused hair loss and skin changes similar to human papular atrichia, suggesting that ODC might be involved in a critical hair follicle function pathway.
March 2021 in “Cell stem cell” This study found that actomyosin contractility in suprabasal keratinocytes influences the proliferation and differentiation of epidermal stem/progenitor cells by acting as a niche element in the skin.

,
June 2004 in “Human molecular genetics online/Human molecular genetics” This study suggests that the HCR risk allele within the PSORS1 locus may contribute to psoriasis susceptibility by altering gene expression related to skin structure and differentiation, although these changes alone might not result in clinical symptoms.
201 citations
,
May 2001 in “Proceedings of the National Academy of Sciences” This study found that transgenic expression of COX-2 in mouse basal keratinocytes causes epidermal hyperplasia and certain dysplastic features at specific body sites.

,
March 2012 in “Molecular Carcinogenesis” This study found that keratin 15 expressing cells from the hair follicle contribute to the development and long-term persistence of cutaneous papillomas in transgenic mice, with a subset showing the Ha-ras mutation.
January 2009 in “Bradford Scholars (University of Bradford)” The study observed that the tumor suppressor activity of bone morphogenetic proteins in mouse skin epithelium depends on Noggin levels, inhibiting Wnt and Shh signaling pathways to prevent tumor initiation and progression.
88 citations
,
August 1998 in “Carcinogenesis” This study found that overexpression of ornithine decarboxylase and activated Ha-ras together led to a high rate of tumor development in a mouse model without additional carcinogens.
41 citations
,
September 2003 in “Journal of Investigative Dermatology” This study suggests that the COX-2 enzyme plays a role in hair follicle biology, as transgenic overexpression in mice induced hair follicle cycling disturbances and alopecia, which was mitigated by COX-2 inhibition.
