Application

Application Comment Organism
medicine isozyme LH2 is of interest as candidate mediator of a p21-independent transcriptional program that regulates the metastatic propensity of KC cells. LH2 promotes lung cancer metastatic behavior and predicts poor prognosis in patients Homo sapiens

Protein Variants

Protein Variants Comment Organism
additional information in syngeneic wild-type Cdkn1a mice, LH2-deficient KC2 tumors are smaller and generate fewer lung metastases than KC2 tumors transfected with scrambled shRNA do Mus musculus
additional information overexpression of isozyme LH2 in osteoblasts induces a switch in the predominant type of collagen cross-link from LCC to HLCC, which qualitatively affects fibrillogenesis and matrix organization Homo sapiens

General Information

General Information Comment Organism
malfunction patients with Bruck syndrome, a recessively inherited disorder with inactivating mutations in the gene encoding LH2 (PLOD2/LH2), have traits of osteogenesis imperfecta with congenital contractures of the large joints. Conversely, skin fibroblasts from patients with systemic sclerosis, a fibrotic disease involving skin and other organs, have elevated LH2 expression and increased production of HLCCs Homo sapiens
physiological function intracellular procollagen-lysine, 2-oxoglutarate 5-dioxygenase enzymes induce hydroxylation of Lys residues on collagen prior to formation of triple helical pro-collagen molecules. Following secretion of pro-collagen molecules into the extracellular space, the telopeptidyl Hyl residues undergo LOX-induced oxidative deamination into Hylald, which then forms Hylald-derived aldimine cross-links that spontaneously rearrange into stable ketoamines; these further mature into stable Hylald-derived collagen cross-links (HLCCs). Epithelial tumor metastasis is preceded by an accumulation of collagen cross-links that heighten stromal stiffness and stimulate the invasive properties of tumor cells. Epithelial tumorigenesis is accompanied by changes in the biochemical type of collagen crosslinks. Ectopic LH2 expression increases cell migration and invasion in Boyden chambers and enhances tumor growth and metastatic capacity in syngeneic wild-type Cdkn1a mice Mus musculus

Epithelial tumor metastasis is preceded by an accumulation of collagen cross-links that heighten stromal stiffness and stimulate the invasive properties of tumor cells. Epithelial tumorigenesis is accompanied by changes in the biochemical type of collagen crosslinks. relative to normal lung tissues, tumor stroma contains higher levels of hydroxylysine aldehyde-derived collagen cross-links (HLCCs) and lower levels of lysine aldehyde-derived cross-links (LCCs), which are the predominant types of collagen cross-links in skeletal tissues and soft tissues, respectively. Lysyl hydroxylase 2 (LH2) hydroxylates telopeptidyl lysine residues on collagen, and shifts the tumor stroma toward a high-HLCC, low-LCC state, increasing tumor stiffness, and enhancing tumor cell invasion and metastasis. LH2 enhances the metastatic properties of tumor cells and functions as a regulatory switch that controls the relative abundance of biochemically distinct types of collagen cross-links in the tumor stroma Homo sapiens
