Efficacy of photodynamic therapy in vulvar lichen sclerosus treatment based on immunohistochemical analysis of CD34, CD44, myelin basic protein, and Ki67 antibodies
Introduction:Lichen sclerosus (LS) is a chronic skin and mucosa inflammatory disease. It affects mainly the female anogenital area especially in postmenopausal period. The main symptoms include pruritus, burning, pain, sometimes urinary problems, or difficulties in defecation. Usually, porcelain-white plaques are seen in the skin and mucosa. The etiology and pathogenesis of LS are still uncertain. There are some research studies on possible genetic predisposition, yet autoimmune, hormonal, or infectious factors are not excluded. The typical treatment of LS is mainly pharmacological, although the alternative treatment method used in LS is photodynamic therapy (PDT), which is noninvasive tech…
The complex interplay between Notch signaling and Snail1 transcription factor in the regulation of epithelial–mesenchymal transition (EMT)
Background The epithelial–mesenchymal transition (EMT) is a highly coordinated process observed during embryonic development and adult tissue repair. It is characterized by the loss of cell–cell adhesion and apicobasal polarity, and the transition to a cell type with a spindle-like phenotype able to migrate through the basal membranes. Methods This review article includes available date from peer-reviewed publications associated with the role of Notch signaling and Snail1 transcription factor in activation and regulation of EMT. Results Growing evidences in the past few years demonstrated a significant role of Notch in EMT activation. It is not surprising because this pathway is the nexus o…
