Abstract
Prolyl 3-hydroxylase 1 (P3H1) has been implicated in cancer development, but no pan-cancer analysis has been conducted on P3H1. In this study, for the first time, aspects associated with P3H1, such as the mRNA expression, any mutation, promoter methylation, and prognostic significance, the relationship between P3H1 and clinicopathological parameters, drug sensitivity, and immune cell infiltration were investigated by searching several databases including The Cancer Genome Atlas (TCGA), Genotype-Tissue Expression (GTEx), cBioPortal, and The Tumor Immune Evaluation Resource (TIMER2.0) using bioinformatics tools. The findings indicate significant differential expression of P3H1 in most tumors when compared to normal tissues, with a strong association with clinical prognosis. A pan-cancer Cox regression analysis revealed that high P3H1 expression is significantly associated with low overall survival in patients with brain lower grade glioma, kidney clear cell carcinoma, adrenocortical cancer, liver hepatocellular carcinoma, mesothelioma, sarcoma, uveal melanoma, bladder urothelial carcinoma, kidney papillary cell carcinoma, kidney chromophobe, thymoma, and thyroid carcinoma. A negative correlation was observed between P3H1 DNA methylation and its expression. P3H1 is significantly associated with infiltrating cells, immune-related genes, tumor mutation burden, microsatellite instability, and mismatch repair. Finally, A significant correlation was found between P3H1 expression and sensitivity to nine drugs. Thus, enhanced P3H1 expression is associated with poor prognosis in a variety of tumors, which may be due to its role in tumor immune regulation and tumor microenvironment. This pan-cancer analysis provides insight into the function of P3H1 in tumorigenesis of different cancers and provides a theoretical basis for further in-depth studies to follow.

Abstract
Rhegmatogenous retinal detachment (RRD) is a sight threatening condition that warrants immediate surgical intervention. To date, 29 genes have been associated with monogenic disorders involving RRD. In addition, RRD can occur as a multifactorial disease through a combined effect of multiple genetic variants and non-genetic risk factors. In this review, we provide a comprehensive overview of the spectrum of hereditary disorders involving RRD. We discuss genotype-phenotype correlations of these monogenic disorders, and describe genetic variants associated with RRD through multifactorial inheritance. Furthermore, we evaluate our current understanding of the molecular disease mechanisms of RRD-associated genetic variants on collagen proteins, proteoglycan versican, and the TGF-β pathway. Finally, we review the role of genetics in patient management and prevention of RRD. We provide recommendations for genetic testing and prophylaxis of at-risk patients, and hypothesize on novel therapeutic approaches beyond surgical intervention.

Abstract
BACKGROUND Osteogenesis imperfecta (OI) is a genetic disorder in which there are problems in tissues containing type I collagen, predominantly the cornea and sclera in the eye. Although there are many studies on problems with the anterior segment of the eye in patients with OI, studies on posterior structures are limited. Involvement of the sclera may affect the retinal nerve fibre layer (RNFL), which is indirectly related to intraocular pressure. In addition, the retina and choroid containing type I collagen may be affected. The aim of the study was to compare the posterior segment structures of the eye, including the RNFL, retina, and choroid, in patients with OI to those of healthy control subjects. METHODS This cross-sectional study recruited 19 patients with OI, as well as 22 age- and gender-similar healthy control subjects. Measurements of the RNFL, retina, and choroid were obtained with optical coherence tomography (Spectralis SD-OCT, Heidelberg Engineering, Heidelberg, Germany). RESULTS Patients with OI (mean age 14.32 ± 5.08 years) and the control group (mean age 13.73 ± 3.56 years) had similar age, refractive error, and intraocular pressure values (p > 0.05). There was no difference between groups in terms of RNFL thickness, including the superonasal, nasal, inferonasal, inferotemporal, temporal, and superotemporal sectors, retinal thickness, and choroidal thickness from five different locations (p > 0.05, for all). CONCLUSION According to these results, OI does not clinically affect the RNFL, retina, and choroid in childhood.

Abstract
Purpose To identify the characteristic corneal biomechanical properties of osteogenesis imperfecta (OI), and to compare the corneal biomechanical properties between OI and keratoconus. Methods We included 46 eyes of 23 patients with OI, 188 eyes of 99 keratoconus patients, and 174 eyes of 92 normal controls to compare corneal biomechanical parameters between OI corneas, keratoconus, and normal controls by using Corneal Visualization Scheimpflug Technology (Corvis ST). Results Patients with OI had significantly higher Corvis biomechanical index (CBI) (P < 0.001), higher tomographic and biomechanical index (TBI) (P = 0.040), lower Corvis Biomechanical Factor (CBiF) (P = 0.034), and lower stiffness parameter at first applanation (SP-A1) (P < 0.001) compared with normal controls. In contrast, OI group showed lower CBI (P < 0.001), lower TBI (P < 0.001), higher CBiF (P < 0.001), and higher SP-A1 (P = 0.020) than keratoconus group. Notably, the stress-strain index (SSI) was not significantly different between the OI and normal controls (P = 1.000), whereas keratoconus showed the lowest SSI compared with OI group (P = 0.025) and normal controls (P < 0.001). Conclusions Although the corneal structures of OI patients are less stable and easier to deform as compared to those of the control group, there is no significant difference in material stiffness observed between the OI and normal controls. In contrast, the corneas of keratoconus showed not only lower structural stability and higher deformability but also lower material stiffness compared with those of OI cornea and normal controls. Translational Relevance The biomechanical alterations are different between OI corneas and keratoconus.

Abstract
BACKGROUND Osteogenesis imperfecta (OI) is a hereditary disease caused by affected collagen type 1. Collagen type 1 is an important structural component of the eye. Ocular manifestations in OI are described in literature, but little is known about the risk of eye diseases in OI. OBJECTIVE To investigate the risk of eye diseases in OI. DESIGN A Danish nationwide register-based cohort study based on data from the Danish National Patient Register. PARTICIPANTS All patients registered with an OI diagnosis between January 1977 and December 2018 matched 1:5 with a reference population on gender and birth month and birth year. MEASUREMENTS Incidence rates (IR) per 1000 patient years and sub-hazard ratio (SHR) for any eye disease, corneal diseases, cataract, refraction disorders, vitreous haemorrhage, retinal detachment, retinopathy, angiopathy, retinal haemorrhage, retinal degeneration, retinal changes, optic nerve disorders, and traumatic eye lesions. RESULTS We identified 907 OI patients (493 women) and 4535 persons (2465 women) in the reference population. The IR for any eye disease was 4.07 [95% CI 3.41-4.85] in the OI cohort and 1.96 [95% CI 1.89-2.12] in the reference cohort. The two diseases with highest incidence was cataract (2.41 [95%CI 1.93-3.03] vs 1.29 [95% CI 1.12-1.47], SHR 1.76 [95% CI 1.34-2.33]) and glaucoma (1.08 [95% CI 0.77-1.51] vs 0.42 [95% CI 0.33-0.54], SHR 2.33 [95% CI 1.55-3.53]). The absolute risk of most other eye diseases was low, but the SHR indicated a higher risk in the OI cohort compared to the reference group showing statistically increased risk of refractive disorders, vitreous haemorrhage, retinal detachment or ruptures, other retinal diseases (i.e., retinopathy, angiopathy, retinal haemorrhage, degeneration, retinal changes), and optic nerve disorders. Corneal diseases and traumatic eye lesions were not statistically significantly increased in OI-patients. CONCLUSION Patients with OI have a higher risk of cataract, refractive disorders, glaucoma, vitreous haemorrhages, retinal detachment/ruptures, retinal diseases, and optic nerve disorders.

Abstract
Leucine proline-enriched proteoglycan 1 has been extensively explored because of its protective function in cell homeostasis and correlation with osteogenesis imperfect. Human osteosarcoma is the most common primary malignant tumor of bone with multiple and complex genomic aberrations. However, the functional role of leucine proline-enriched proteoglycan 1 is still unknown in osteosarcoma. Thus we performed this study to explain the leucine proline-enriched proteoglycan 1 effect in osteosarcoma. Gene arrays of human osteosarcoma were downloaded from the Gene Expression Omnibus database. Quantitative real-time PCR was conducted to assess the expression of leucine proline-enriched proteoglycan 1 in osteosarcoma cell lines. Then we attenuated leucine proline-enriched proteoglycan 1 expression in MG63 cells by siRNA strategy and assessed the effect of leucine proline-enriched proteoglycan 1 on cell proliferation, migration and invasion through in-vitro experiments. Additionally, we detected the role of leucine proline-enriched proteoglycan 1 knockdown on PI3K/AKT pathway-related proteins using western blotting. Leucine proline-enriched proteoglycan 1 was increased in osteosarcoma tissues and cells. The overall survival curve demonstrated that high-regulated leucine proline-enriched proteoglycan 1 was linked with poor prognosis of patients with osteosarcoma. The capabilities of proliferation, migration and invasion were all inhibited in MG63 cell because of the downregulation of leucine proline-enriched proteoglycan 1. Furthermore, the expression of phosphorylated PI3K and AKT was impaired after knockdown the leucine proline-enriched proteoglycan 1 as well as P70S6K. In conclusion, leucine proline-enriched proteoglycan 1 might function as an important therapeutic factor in human osteosarcoma through regulating the PI3K/AKT signaling pathway.

Abstract
Osteogenesis imperfecta (OI) type VIII (OMIM: 610915) is a rare autosomal recessive disorder characterized by white sclerae, severe growth deficiency, and bone fragility. This condition results from pathogenic variants of P3H1, a gene that codes for P3H1, an important protein involved in the prolyl-3-hydroxylation complex required for collagen type I folding. Here, we described a woman with OI type VIII due to a homozygous mutation of c.1914+1G>C (NM_001243246.1) in P3H1 and retinal detachment. We compared our case to five severe OI and retinal detachment cases reported in the literature. The only case previously reported with a molecular diagnosis had a similar mutation in P3H1 c.1914+1G>A and a giant retinal detachment. We suggest that individuals with OI type VIII should be submitted to careful fundoscopic examination.

Abstract
Telescopic rodding has been developed in order to obtain long-lasting osteosynthesis in the growing long bones of children with osteogenesis imperfecta (OI). The major and still unsolved drawback of any telescopic rod or nail design is a lack of rotational stability and, currently, no telescopic system allows immediate weight-bearing. When these problems are associated with insufficient longitudinal bone stability and diminished healing capacity, the result can be unfavourable causing secondary bone fragment displacement, delayed or non-union. This article presents a case report of operative treatment in a 9-year-old girl affected with OI type VIII complicated with postoperative defect and pseudarthrosis of the femur causing functional impairment with loss of walking ability. A combination of intramedullary flexible nailing and minimal external fixation was applied for treatment of femoral defect-pseudarthrosis in a girl of 9 years with OI type VIII. Intramedullary and extramedullary nails with wrapping of titanium nickel mesh subperiosteally provided osteosynthesis and deformity correction of the tibia of a small intramedullary canal diameter. Upright standing and walking with progressive weight-bearing was started 4 days after surgery. There were no septic or vascular complications nor complications related to Ilizarov fixator. Radiographs demonstrated bone union in the femur 46 days after surgery. At the follow-up visit 9 months after fixator removal, clinical alignment remained excellent without any relapse of deformity. Bone remodelling with restitution of medullary canal was noted on lower limb radiographs. The patient was able to stand and walk without pain with an aide or walker. At the follow-up visit 17 months after fixator removal, there was no decrease in achieved functional abilities and the treatment outcome remained satisfactory. Use of an external fixator with intramedullary nailing for treatment of postoperative pseudarthrosis in patient with severe OI (recessive form of OI, type VIII) provides longitudinal, rotational and angular stability. Furthermore, this approach ensured early functional activity and walking with full weight-bearing, both favourable conditions for bone tissue regeneration. The external fixator was applied for a short period and only for additional stability and not for progressive deformity correction or other manipulation. In addition, the combination of intramedullary and extramedullary nailing and subperiosteal titanium nickel mesh seems to be promising for osteosynthesis in the deformity correction of bones with small diameter in children with OI.
