Elastin-like polypeptides (ELPs) are synthetic biopolymers with potential applications in the fields of cancer therapy, tissue scaffolding, metal recovery, and protein purification. For cancer therapy, the addition of functional groups to ELPs can enable them to conjugate with cytotoxic drugs. [ 1 ]
Skin elastosis causes Condition Distinctive features Histopathology Actinic elastosis (most common, also called solar elastosis) Elastin replacing collagen fibers of the papillary dermis and reticular dermis: Elastosis perforans serpiginosa: Degenerated elastic fibers and transepidermal perforating canals (arrow in image points at one of them) [18]
Elastin is a protein encoded by the ELN gene in humans and several other animals. Elastin is a key component in the extracellular matrix of gnathostomes (jawed vertebrates). [ 5 ] It is highly elastic and present in connective tissue of the body to resume its shape after stretching or contracting. [ 6 ]
Stem cells give rise to progenitor cells, which are cells that are not self-renewing, but can generate several types of cells. The extent of stem cell involvement in cutaneous (skin) wound healing is complex and not fully understood. [citation needed] Stem cell injection leads to wound healing primarily through stimulation of angiogenesis. [70]
Cutaneous squamous-cell carcinoma is the second-most common cancer of the skin (after basal-cell carcinoma, but more common than melanoma). It usually occurs in areas exposed to the sun. Sunlight exposure and immunosuppression are risk factors for SCC of the skin, with chronic sun exposure being the strongest environmental risk factor. [26]
Lysyl oxidase has also proven crucial to the development of the respiratory system and the skin, as collagen and elastin represent 50-60% of the composition of the lung, and 75% of the skin. In Lox homozygous null models ( Lox -/- ), the activity of LOX was reduced by up to 80%, and the phenotype of the lungs resembles those of patients with ...
