Actinic elastosis, also known as solar elastosis, is an accumulation of abnormal elastin (elastic tissue) in the dermis of the skin, [2] or in the conjunctiva of the eye, [3] which occurs as a result of the cumulative effects of prolonged and excessive sun exposure, a process known as photoaging.
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 ]
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 ]
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]
Hereditary connective tissue disorders are a diverse set of broad, single-gene disorders that impact one or more of the main components of connective tissues, such as ground substance (glycosaminoglycans), collagen, or elastin. Many result in anomalies of the skeleton and joints, which can substantially impair normal growth and development.
Skin cancer is the most commonly diagnosed form of cancer in humans. [11] [12] [13] There are three main types of skin cancers: basal-cell skin cancer (BCC), squamous-cell skin cancer (SCC) and melanoma. [1] The first two, along with a number of less common skin cancers, are known as nonmelanoma skin cancer (NMSC).
With increasing tissue deformation the collagen is gradually stretched in the direction of deformation. When taut, these fibers produce a strong growth in tissue stiffness. The composite behavior is analogous to a nylon stocking, whose rubber band does the role of elastin as the nylon does the role of collagen. In soft tissues, the collagen ...
Elaunin (Greek verb ἐλαύνω "I steer") is a component of elastic fibers formed from deposition of elastin between oxytalan fibers. It is found in the periodontal ligament and the connective tissue of the dermis, particularly in association with sweat glands. [1]
