Objective To study TCF3 expression in back skin of C57BL/6 (B6) mice in treatment of tetradecanoylphorbol acetate (TPA). Methods Seven-week old B6 mice were treated with TPA (TPA group) or acetone (acetone group) on their back skins for 1
2 and 4 weeks
respectively. Immunofluorescence
RT-PCR and Western blotting were applied to examine TCF3 expression in hair follicles of mice. Results Compared with the acetone group
the back skins of the TPA group were thicker
and the resting hair follicles transformed into growing hair follicles after the treatment of TPA for 4 weeks. After the treatment of TPA for 1and 2 weeks
the protein and mRNA level of TCF3 was up-regulated and TCF3 was mainly expressedin the nuclei of hair follicle bulge and secondary hair germ. After the treatment of TPA for 4 weeks
TCF3 was upregulated in the protein and mRNA level and was mainly expressed in hair follicle bulge and hair follicle stem cells in the out root sheath. However
TCF3 of the acetone group was expressed in hair follicle bulge and secondary hair germ all the time. Conclusion TPA can promote abnormal activation of hair follicle stem cells and meanwhile induce up-regulation of TCF3.
