We have previously provided molecular evidence of expression of aquaporin 3 (AQP3) in normal human urothelium and in UBC of various stages. Whereas former studies demonstrated that loss of AQP3 was associated with invasive and high-grade disease and worse progression-free and cancer-specific survival, this report investigates the expression of AQP3 in associated CIS. Contrary to what we had expected, all CIS specimens were shown to exhibit strong AQP3 expression, suggesting loss of AQP3 in UBC is primarily associated with the ability of tumor cells for invasion but not with grading as sign of dedifferentiation.

Skin wound healing is a complex process involving various cellular and molecular events. However, chronic wounds, particularly in individuals with diabetes, often experience delayed wound healing, potentially leading to diabetic skin complications. In this study, we examined the effects of umbelliferone on skin wound healing using dermal fibroblasts and skin tissues from a type 2 diabetic mouse model.

Skin ageing is influenced by both intrinsic and extrinsic factors, with excessive ultraviolet (UV) exposure being a significant contributor. Such exposure can lead to moisture loss, sagging, increased wrinkling, and decreased skin elasticity. Prolonged UV exposure negatively impacts the extracellular matrix by reducing collagen, hyaluronic acid, and aquaporin 3 (AQP-3) levels.

Three genes involved in poly-γ-glutamic acid(γ-PGA)synthesis cloned from Bacillus licheniformis were transformed into cucumber for the first time. Compared with control, its water content increased by 6-14 % and water loss rate decreased by 11-12 %. In zebrafish and human skin experiments, the moisturizing effect of transgenic cucumber was significantly higher than that of CK, γ-PGA and hyaluronic acid group.
