Collagen XI alpha 1 (Col11a1) is an extracellular matrix molecule required for embryonic development with a role in both nucleating the formation of fibrils and regulating the diameter of heterotypic fibrils during collagen fibrillar assembly. Although found in many different tissues throughout the vertebrate body, Col11a1 plays an essential role in endochondral ossification. To further underst...

BACKGROUND The single nucleotide polymorphism (SNP) rs2615977 is associated with osteoarthritis (OA) and is located in intron 31 of COL11A1, a strong candidate gene for this degenerative musculoskeletal disease. Furthermore, the common non-synonymous COL11A1 SNP rs1676486 is associated with another degenerative musculoskeletal disease, lumbar disc herniation (LDH). rs1676486 is a C-T transition...

Despite the progress achieved in the treatment of breast cancer, there are still many unsolved clinical issues, being the diagnosis, prognosis, and treatment of papillary diseases, one of the highest challenges. Because of its unpredictable clinical behavior, treatment of intraductal papilloma has generated a great controversy. Even though considered as a benign lesion, it presents high rate of...

PURPOSE To identify mutations in COL2A1 and COL11A1 genes and to examine the genotype-phenotype correlation in a cohort of Chinese patients with Stickler syndrome. METHODS A total of 16 Chinese probands with Stickler syndrome were recruited, including nine with a family history of an autosomal dominant pattern and seven sporadic cases. All patients underwent full ocular and systemic examinati...

Background: Collagen type XI, alpha 1 (COL11A1) is a minor component of extracellular matrix and its overexpression associated with tumoral progression poorer outcome in several human cancers; data on breast cancer are promising but scarce. FGD3 expression has been shown to be strong independent prognostic factor cancer. The aim our study was investigate whether COL11A1 correlates other classic...

BACKGROUND Stickler syndromes types 1, 2 and 3 are usually dominant disorders caused by mutations in the genes COL2A1, COL11A1 and COL11A2 that encode the fibrillar collagens types II and XI present in cartilage and vitreous. Rare recessive forms of Stickler syndrome exist that are due to mutations in genes encoding type IX collagen (COL9A1 type 4 Stickler syndrome and COL9A2 type 5 Stickler sy...

BACKGROUND The collagen11A1 (COL11A1) gene is overexpressed in pancreatic cancer. The expression of COL11A1 protein could be involved in desmoplastic events in pancreatic cancer, but an antibody that specifically stains the COL11A1 protein is not currently available. METHODS AND FINDINGS A total of 54 pancreatic ductal adenocarcinomas (PDAC), 23 chronic pancreatitis (CP) samples, and cultured...

Aim Due to limited information on these genes and to a better understanding of common biomarkers associated with cancer of the digestive tract routes, we aim to evaluated expression level of Olfactomedin4 (OLFM4) and (pro)collagen11A1/COL11A1 genes in people with gastric cancer in Iran. Background Gastric cancer is one of the main cause of cancer death. The early prognosis of gastric cancer i...

PURPOSE To investigate the association of PLEKHA7 and COL11A1 with primary angle closure glaucoma, as well as acute and chronic subphenotype, in a Han Chinese population. METHODS A total of 984 cases, including 606 primary angle closure glaucoma (PACG) and 378 primary angle closure (PAC), and 922 normal controls were recruited. Twelve single nucleotide polymorphisms (SNPs) (rs1676486, rs37538...

Stickler and Marshall syndromes are dominantly inherited chondrodysplasias characterized by midfacial hypoplasia, high myopia, and sensorineural-hearing deficit. Since the characteristics of these syndromes overlap, it has been argued whether they are distinct entities or different manifestations of a single syndrome. Several mutations causing Stickler syndrome have been found in the COL2A1 gen...
