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 ]
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 ]
Merkel cell carcinoma (MCC) is a rare and aggressive skin cancer occurring in about three people per million members of the population. [1] It is also known as cutaneous APUDoma, primary neuroendocrine carcinoma of the skin, primary small cell carcinoma of the skin, and trabecular carcinoma of the skin. [2]
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 ...
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]
In the earlier stages of actinic elastosis, elastic fiber proliferation can be seen in the dermis. As the condition becomes more established, the collagen fibers of the papillary dermis and reticular dermis become increasingly replaced by thickened and curled fibers that form tangled masses and appear basophilic under routine haematoxylin and eosin staining.
Type IV collagen is expressed close to the cancer cells in vivo, forming basement membrane like structures on the cancer cell surface that colocalize with the integrin receptors. The interaction between type IV collagen produced by the cancer cell, and integrins on the surface of the cancer cells, are important for continuous cancer cell growth ...
