Computational predictions of the tensile properties of electrospun fibre meshes: Effect of fibre diameter and fibre orientation
(2008)The mechanical properties of biomaterial scaffolds are crucial for their efficacy in tissue engineering and regenerative medicine. At the microscopic scale, the scaffold must be sufficiently rigid to support cell adhesion, ...

Mutation in a gene for type I procollagen (COL1A2) in a woman with postmenopausal osteoporosis: Evidence for phenotypic and genotypic overlap with mild osteogenesis imperfecta
(1991)Mutations in the two genes for type I collagen (COL1A1 or COL1A2) cause osteogenesis imperfecta (OI), a heritable disease characterized by moderate to extreme brittleness of bone early in life. Here we show that a 52-year-old ...

Pirfenidone normalizes the tumor microenvironment to improve chemotherapy
(2017)Normalization of the tumor microenvironment by selectively targeting components of the tumor extracellular matrix has been recently proposed to have the potential to decompress tumor blood vessels, increase vessel perfusion ...

A sequence polymorphism in the 3′-nontranslated region of the proα1 chain of type I procollagen
(1990)

Article
A single base mutation that converts glycine 907 of the α2(I) chain of type I procollagen to aspartate in a lethal variant of osteogenesis imperfecta. The single amino acid substitution near the carboxyl terminus destabilizes the whole triple helix
(1989)Type I procollagen was examined in cultured skin fibroblasts from a patient with a lethal variant of osteogenesis imperfecta. About half of the pro-α chains were post-translationally overmodified and had a decreased thermal ...

Somatic cell mosaicism: Another source of phenotypic heterogeneity in nuclear families with osteogenesis imperfecta
(1993)Mutations in the genes coding for the proα1 and proα2 chains of type I procollagen have been found in many patients with osteogenesis imperfecta (OI), a heritable disorder of connective tissue. The severity of the disease ...

The substitution of arginine for glycine 85 of the α1(I) procollagen chain results in mild osteogenesis imperfecta. The mutation provides direct evidence for three discrete domains of cooperative melting of intact type I collagen
(1991)We report a case of mild osteogenesis imperfecta in a 56-year-old male undergoing aortic valve replacement surgery. The primary defect in this patient was the substitution of arginine for glycine 85 in one of the two chains ...

Substitution of cysteine for glycine-α1-691 in the proα1(I) chain of type I procollagen in a proband with lethal osteogenesis imperfecta destabilizes the triple helix at a site C-terminal to the substitution
(1991)Skin fibroblast from a proband with lethal osteogenesis imperfecta synthesized a type I procollagen containing a cysteine residue in the α1(I) helical domain. Assay of thermal stability of the triple helix by proteinase ...

Article
Substitution of serine for α1(I)-glycine 844 in a severe variant of osteogenesis imperfecta minimally destabilizes the triple helix of type I procollagen. The effects of glycine substitutions on thermal stability are either position or amino acid specific
(1989)Recent reports have demonstrated that a series of probands with severe osteogenesis imperfecta had single base mutations in one of the two structural genes for type I procollagen that substituted amino acids with bulkier ...

Vasodilator-Stimulated Phosphoprotein (VASP) depletion from breast cancer MDA-MB-231 cells inhibits tumor spheroid invasion through downregulation of Migfilin, β-catenin and urokinase-plasminogen activator (uPA)
(2017)A hallmark of cancer cells is their ability to invade surrounding tissues and form metastases. Cell-extracellular matrix (ECM)-adhesion proteins are crucial in metastasis, connecting tumor ECM with actin cytoskeleton thus ...
