TLDR
It is shown that mice lacking the protein lysyl oxidase–like 1 (LOXL1) do not deposit normal elastic fibers in the uterine tract post partum and develop pelvic organ prolapse, enlarged airspaces of the lung, loose skin and vascular abnormalities with concomitant tropoelastin accumulation.Abstract:
Elastic fibers are components of the extracellular matrix and confer resilience1. Once laid down, they are thought to remain stable2, except in the uterine tract where cycles of active remodeling occur3. Loss of elastic fibers underlies connective tissue aging and important diseases including emphysema4,5,6,7. Failure to maintain elastic fibers is explained by a theory of antielastase-elastase imbalance8, but little is known about the role of renewal. Here we show that mice lacking the protein lysyl oxidase–like 1 (LOXL1) do not deposit normal elastic fibers in the uterine tract post partum and develop pelvic organ prolapse, enlarged airspaces of the lung, loose skin and vascular abnormalities with concomitant tropoelastin accumulation. Distinct from the prototypic lysyl oxidase (LOX), LOXL1 localizes specifically to sites of elastogenesis and interacts with fibulin-5. Thus elastin polymer deposition is a crucial aspect of elastic fiber maintenance and is dependent on LOXL1, which serves both as a cross-linking enzyme and an element of the scaffold to ensure spatially defined deposition of elastin.read more

TL;DR: In this paper, the authors investigated the bladder and urethral function in a rat model lacking the protein lysyl oxidase-like 1 (Loxl1) and found increased looseness and redundancy of the skin, decreased intercontraction interval and voided volume in cystometry, lower leak-point pressure, thinner elastic fibers of the mesentery, bladder, urethra and vagina, and smaller contractile response of detrusor strips to carbachol when compared to the WT rats.

Requirement for Macrophage Elastase for Cigarette Smoke-Induced Emphysema in Mice
TL;DR: Smoke-exposed MME-/- mice that received monthly intratracheal instillations of monocyte chemoattractant protein-1 showed accumulation of alveolar macrophages but did not develop air space enlargement, indicating that macrophage elastase is probably sufficient for the development of emphysema that results from chronic inhalation of cigarette smoke.

Lysyl oxidase: Properties, specificity, and biological roles inside and outside of the cell
TL;DR: Although the three‐dimensional structure of LO has yet to be determined, the present treatise offers hypotheses based upon its primary sequence, which may underlie the prominent electrostatic component of its unusual substrate specificity as well as the catalysis‐suppressing function of the propeptide domain of prolysyl oxidase.

TL;DR: It is reported that fibulin-5 (also known as DANCE), a recently discovered integrin ligand, is an essential determinant of elastic fibre organization and may provide anchorage of elastic fibres to cells, thereby acting to stabilize and organize elastic fibre in the skin, lung and vasculature.

TL;DR: Fibulin-5-/- mice develop marked elastinopathy owing to the disorganization of elastic fibres, with resulting loose skin, vascular abnormalities and emphysematous lung, which resembles the cutis laxa syndrome in humans.
