Altered hemodynamics due to aortic stenosis and regurgitation and also defects in aortic media like elastin fragmentation, decreased fibrillin, matrix disruption, loss of smooth muscle and increase in collagen have been thought to be the cause.
Fibrillin is an important part of connective tissue, the diseases of which can affect several parts of the body; such as skin, muscles, skeleton, pulmonary system, blood vessels in varying degrees (3, 7).
This gene contains 66 exons, is located on chromosome 15q21.1 and encodes fibrillin, an important protein of the extracellular matrix, that contributes to the final structure of a microfibril (1, 2).
During photoaging there is also an accumulation of degenerated elastic fibers combined with other proteins, such as glycosaminoglycans, fibrillin, and lysozyme, which are deposited in the upper dermis triggering elastosis [18].

The accumulation of fibronectin in the extracellular space also modulates the secretion of other repairing components such as collagen type I and type III, tenascin, laminin, and fibrillin.
A recent study found that miR29 acts as an antifibrotic factor by accelerating the expression of multiple extracellular matrix genes including elastin [61], fibrillin 1 (Fbn1), collagen type I, [alpha] 1 and 2 (Col1[alpha]1, Col1[alpha]2), collagen type III, [alpha]1 (Col3[alpha]1), and fibronectin (FBN) [62,63].
The pathogenesis of striae is unknown but probably relates to changes in the components of extracellular matrix, including fibrillin, elastin and collagen.
