Abstract
Drugs that can treat one disease may either be detrimental or beneficial toward another due to possible cross-interactions. Therefore, care in choosing a suitable drug for patients with multiple diseases is crucial in successful patient management. This study explores several currently available ophthalmic drugs used to treat common ocular diseases to understand how they can affect the amyloidogenesis of a transforming growth factor β-induced protein (TGFBIp) peptide fragment found in abundance in the corneal protein aggregation deposits of lattice corneal dystrophy (LCD) patients. Results from this study provided supporting evidence that some drugs intended to treat other diseases can enhance or inhibit fibrillar aggregation of TGFBIp peptide, which may have potential implication of affecting the disease progression of LCD by either worsening or ameliorating it. Comparisons of the different properties of ophthalmic compounds explored in this study may also provide some guidance for future design of drugs geared toward the treatment of LCD.

Iordache S, Cursaru A, Serban B, Costache M, Spiridonica R, Cretu B, Cirstoiu C. Melorheostosis: A Review of the Literature and a Case Report. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59050869. [PMID: 37241101 DOI: 10.3390/medicina59050869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/24/2023] [Revised: 04/07/2023] [Accepted: 04/28/2023] [Indexed: 05/28/2023]
Abstract
Background and Objectives: Melorheostosis, also referred to in the literature as Leri's disease, is an unusual mesenchymal dysplasia with the clinical appearance of benign sclerosing bone dysplasia; it frequently occurs in late adolescence. Any bone in the skeletal system can be affected by this disease, though the long bones of the lower extremities are the most common, at any age. Melorheostosis has a chronic evolution, and symptoms are usually absent in the early stages. The etiopathogenesis is still unknown, however, numerous theories have been proposed that could explain the appearance of this lesion formation. An association with other benign or malignant bone lesions is also possible, and associations with osteosarcoma, malignant fibrous histiocytoma, or Buschke-Ollendorff syndrome have also been reported. There have also been reported cases of the malignant transformation of a pre-existing melorheostosis lesion into malignant fibrous histiocytoma or osteosarcoma. The diagnosis of melorheostosis can be made only based on radiological images, but, due to its polymorphism, additional imaging investigations are often necessary and sometimes only a biopsy can establish a definite diagnosis. Because there are currently no guidelines for treatment based on scientific evidence, due to the low number of cases diagnosed worldwide, our objective was to highlight the early recognition and specific surgical treatments for better prognosis and outcomes. Materials and Methods: We conducted a review of the literature consisting of original papers, case reports, and case series and presented the clinical and paraclinical characteristics of melorheostosis. We aimed to synthesize the treatment methods available in the literature as well as determine possible future directions related to the treatment of melorheostosis. Furthermore, we presented the results of a case of femoral melorheostosis admitted to the orthopedics department of the University Emergency Hospital of Bucharest in a 46-year-old female patient with severe pain in the left thigh and limitation of joint mobility. Following the clinical examination, the patient complained of pain in the middle third of the left thigh in the antero-medial compartment; the pain appeared spontaneously and was aggravated during physical activity. The pain started about two years prior, but the patient experienced complete pain relief after the administration of non-steroidal anti-inflammatory drugs. In the last six months, the patient presented an increase in pain intensity without significant improvement following the administration of non-steroidal anti-inflammatory drugs. The patient's symptoms were mainly determined by the increase in the volume of the tumor and the mass effect on the adjacent tissues, especially on the vessels and the femoral nerve. The CT examination and bone scintigraphy showed a unique lesion in the middle third of the left femur and no oncological changes in the thoracic, abdominal, and pelvic regions; however, at the level of the femoral shaft, there was a localized cortical and pericortical bone lesion formation that surrounded approximately 180 degrees of the femoral shaft (anterior, medial, and lateral). It had a predominantly sclerotic structure but was associated with lytic areas with thickening of the bone cortex and areas of periosteal reaction. The next therapeutic gesture was to perform an incisional biopsy using a lateral approach at the level of the thigh. The histopathological result supported the diagnosis of melorheostosis. Additionally, immunohistochemical tests completed the data obtained after the microscopic examination through the classic histopathological technique The patient was discharged and included in a full medical recovery program for eight weeks in a specialized medical center, during which she also received analgesic treatment in maximum doses, but without improvement regarding her symptoms. Taking into account the chronic evolution of the pain, the complete lack of response to conservative treatment after eight weeks, and the lack of treatment guidelines in the case of melorheostosis, a surgical approach needed to be considered. The surgical option in this case, considering the circumferential location of the lesion at the level of the femoral diaphysis, was a radical resection. The surgical approach consisted of segmental resection to healthy bone tissue and reconstruction of the remaining defect with a modular tumoral prosthesis. At the 45-day postoperative control, the patient no longer complained of pain in the operated-on limb and was mobile with full support without gait difficulties. The follow-up period was one year, and the patient presented complete pain relief and a very good functional outcome. Results: In the case of asymptomatic patients, conservative treatment seems to be a good option with optimal results. However, for benign tumors, it remains unclear whether radical surgery is a viable option. Conclusions: Melorheostosis remains an incompletely understood disease, given the limited number of cases worldwide, and thus, there is a lack of clinical guidelines regarding specialized treatment.

Abstract
Extracellular matrix proteins are associated with metabolically healthy adipose tissue and regulate inflammation, fibrosis, angiogenesis, and subsequent metabolic deterioration. In this study, we demonstrated that transforming growth factor-beta (TGFBI), an extracellular matrix (ECM) component, plays an important role in adipose metabolism and browning during high-fat diet-induced obesity. TGFBI KO mice were resistant to adipose tissue hypertrophy, liver steatosis, and insulin resistance. Furthermore, adipose tissue from TGFBI KO mice contained a large population of CD11b+ and CD206+ M2 macrophages, which possibly control adipokine secretion through paracrine mechanisms. Mechanistically, we showed that inhibiting TGFBI-stimulated release of adipsin by Notch-1-dependent signaling resulted in adipocyte browning. TGFBI was physiologically bound to Notch-1 and stimulated its activation in adipocytes. Our findings revealed a novel protective effect of TGFBI deficiency in obesity that is realized via the activation of the Notch-1 signaling pathway.

Abstract
INTRODUCTION Transforming growth factor beta induced (TGFBI) gene mutations have been reported as the cause of a group of genetically inherited, visually debilitating, corneal dystrophies (CD). A scoping literature review to identify and categorize compounds that inhibit corneal TGFBI expression and/or promote TGFBIp degradation was performed. Emphasis was given to their potential to be used as a cost-effective approach via drug repurposing. AREAS COVERED We performed a thorough search of original peer-reviewed literature using electronic bibliographic databases and selected articles according to a set of criteria. The total number of articles retrieved from the search terms applied to the databases was 2344. The number of relevant full-text articles included added up to 19. We identified 16 compounds that can theoretically reduce the levels of mutant TGFBIp in human corneal cells. EXPERT OPINION Currently, the only temporary treatments available for this condition are lubricant drops and surgery. Here, we explored the crosstalk between cascades that regulate TGFBI expression and identified compounds that target these pathways. Compounds that inhibit DNA synthesis and function, increase elimination of TGFBIp or bind to mutant TGFBIp were also explored with the aim of highlighting promising compounds that can be used in future cost-effective drug-repurposing studies.

Abstract
Many cancer types metastasize to bone. This propensity may be a product of genetic traits of the primary tumour in some cancers. Upon arrival, cancer cells establish interactions with various bone-resident cells during the process of colonization. These interactions, to a large degree, dictate cancer cell fates at multiple steps of the metastatic cascade, from single cells to overt metastases. The bone microenvironment may even influence cancer cells to subsequently spread to multiple other organs. Therefore, it is imperative to spatiotemporally delineate the evolving cancer-bone crosstalk during bone colonization. In this Review, we provide a summary of the bone microenvironment and its impact on bone metastasis. On the basis of the microscopic anatomy, we tentatively define a roadmap of the journey of cancer cells through bone relative to various microenvironment components, including the potential of bone to function as a launch pad for secondary metastasis. Finally, we examine common and distinct features of bone metastasis from various cancer types. Our goal is to stimulate future studies leading to the development of a broader scope of potent therapies.

Abstract
INTRODUCTION Melorheostosis is a rare sclerosing bone disease characterized by linear hyperostotic bone dysplasia with its radiological appearance as melting candle wax dripping by its side. It usually affects long bones, especially the lower limb. The exact cause of the disease has not been clearly explained though many theories are available. It is insidious in onset and symptoms being pain, deformity, and joint stiffness. Although there is no definitive treatment, the administration of bisphosphonates dramatically reduces pain and improves the patient clinically. CASE REPORT We described a case of a 28-year-old female who presented with a history of pain and swelling in her left leg for the past 2 years. The onset of complaints was insidious. On physical examination, there was tender swelling over the shaft of the tibia with irregular borders. Knee and ankle range of movements were normal. Radiographs showed hyperostosis of the proximal two-thirds of the tibia of the left leg with a flowing candle wax appearance. The patient was treated with a single dose of intravenous zolendronic acid and physical therapy. The patient had dramatic alleviation of pain without the need for any further treatment till 1 year follow-up. CONCLUSION Although there is no specific treatment available for this disease, the intravenous infusion of zolendronic acid has dramatically improved the patient clinically.

Abstract
Several studies have suggested that extracellular matrix (ECM) remodeling and the microenvironment are tightly associated with adipogenesis and adipose angiogenesis. In the present study, we demonstrated that transforming growth factor-beta induced (TGFBI) suppresses angiogenesis stimulated by adipocyte-conditioned medium (Ad-CM), both in vitro and in vivo. TGFBI knockout (KO) mice exhibited increased numbers of blood vessels in adipose tissue, and blood vessels from these mice showed enhanced infiltration into Matrigel containing Ad-CM. The treatment of Ad-CM-stimulated SVEC-10 endothelial cells with TGFBI protein reduced migration and tube-forming activity. TGFBI protein suppressed the activation of the Src and extracellular signaling-related kinase signaling pathways of these SVEC-10 endothelial cells. Our findings indicated that TGFBI inhibited adipose angiogenesis by suppressing the activation of Src and ERK signaling pathways, possibly because of the stimulation of the angiogenic activity of endothelial cells.

Abstract
The outbreak of the highly contagious and deadly severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), also known as coronavirus disease 2019 (COVID-19), has posed a serious threat to public health across the globe, calling for the development of effective diagnostic markers and therapeutics. Here, we report a highly reliable severity diagnostic biomarker, acetylated 676th lysine transforming growth factor-beta-induced protein (TGFBIp K676Ac). TGFBIp K676Ac was consistently elevated in the blood of patients with SARS-CoV-2 pneumonia (n = 113), especially in patients in the intensive care unit (ICU) compared to non-ICU patients. Patients' blood samples showed increased cytokines and lymphopenia, which are exemplary indicators of SARS-CoV-2 pneumonia. Treatment with TGFBIp neutralizing antibodies suppressed the cytokine storm. The increased level of TGFBIp K676Ac in ICU patients suggests the promise of this protein as a reliable severity diagnostic biomarker for severe SARS-CoV-2 disease.

Abstract
Sepsis is a potentially fatal complication of infections and there are currently no effective therapeutic options for severe sepsis. In this study, we revealed the secretion mechanism of transforming growth factor β-induced protein (TGFBIp) that was recently identified as a therapeutic target for sepsis, and designed TGFBIp acetylation inhibitory peptide (TAIP) that suppresses acetylation of lysine 676 in TGFBIp. To improve bioavailability and biodegradation of the peptide, TAIP was conjugated to polyamidoamine (PAMAM) dendrimers. Additionally, the cell-penetrating peptide (CPP) was conjugated to the TAIP-modified PAMAM dendrimers for the intracellular delivery of TGFBIp. The resulting nanostructures, decorated with TAIP and CPP via poly(ethylene glycol) linkage, improved the mortality and organ damage in the septic mouse model and suppressed lipopolysaccharide-activated severe vascular inflammatory responses in endothelial cells. Thus, the dendrimer-based nanostructures for delivery of TAIP using CPP show great promise in practical applications in sepsis therapy.

[PMID: 30312962 PMCID: PMC6180235 DOI: 10.1016/j.ijscr.2018.09.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2018] [Revised: 08/31/2018] [Accepted: 09/05/2018] [Indexed: 11/28/2022] Open
Abstract
Melorheostosis of the elbow associated with elbow stiffness is extremely rare. In the standard radiology or orthopedics literature Melorheostosis (from the Greek: melos = limb, rheos = flow) is described monotonously as a “flowing hyperostosis” resembling dripping candle wax. Patients with this condition may have joint pain, stiffness, deformity, and restricted range of motion due to bony and soft-tissue contracture. Involvement usually follows a sclerotomal distribution and usually affects only one extremity. There is no standard treatment for melorheostosis, and management plans must be made on an individual patient basis. The aims of treatment are pain relief and maintaining function. Some Surgical treatment for this condition includes tendon lengthening, excision of fibrous and osseous tissue, fasciotomy, capsulotomy, sympathectomy, corrective osteotomy, Ilizarov lengthening, arthrodesis, implant arthroplasty, and even amputation of severely affected limbs with vascular ischemia. In this study we found that debridement arthroplasty is safe and effective in treating elbow stiffness associated with Melorheostosis.
Introduction Elbow stiffness is a common condition that affects the quality of life of patients. Melorheostosis of the elbow associated with elbow stiffness is extremely rare. Presentation of case We report the case of a 28 yr old male who presented with elbow stiffness which occurred within one year without prior history of trauma or infection. The patient had decrease in range of motion together with progressive worsening pain that forced him to seek medical attention. Discussion There is no standard treatment for melorheostosis, and management plans must be made on an individual patient basis. The aims of treatment are pain relief and maintaining function. Conclusion Debridement arthroplasty is safe and effective in treating elbow stiffness associated with Melorheostosis.

Abstract
Background A 20-year-old Danish woman with melorheostosis in her right femoral shaft and disabling pain in the affected area, whose symptoms did not in the long term respond to zoledronic acid, experienced continuous remission of pain after treatment with denosumab. To the best of our knowledge, this is the first case report on denosumab treatment for melorheostosis. Case presentation Radiologic findings and bone biopsy showed irregular cortical hyperostosis in the right femoral shaft with increased tracer uptake on Tc99-bone scan. The diagnosis of melorheostosis was made based on the radiological findings. There was a good initial response to zoledronic acid administration, but after relapse of pain, the second and third administrations had a poor effect. As a second line of treatment denosumab was administered at 8-week intervals, the frequency was based on our patient’s symptoms and on biochemical markers of bone turnover. Conclusion This is the first report indicating that denosumab has a place in the treatment of melorheostosis when the effect of bisphosphonate treatment is insufficient.

Abstract
The Fasciclin 1 (FAS1) domain is an ancient structural motif in extracellular proteins present in all kingdoms of life and particularly abundant in plants. The FAS1 domain accommodates multiple interaction surfaces, enabling it to bind different ligands. The frequently observed tandem FAS1 arrangement might both positively and negatively regulate ligand binding. Additional protein domains and post-translational modifications are partially conserved between different evolutionary clades. Human FAS1 family members are associated with multiple aspects of health and disease. At the cellular level, mammalian FAS1 proteins are implicated in extracellular matrix structure, cell to extracellular matrix and cell to cell adhesion, paracrine signaling, intracellular trafficking and endocytosis. Mammalian FAS1 proteins bind to the integrin family of receptors and to protein and carbohydrate components of the extracellular matrix. FAS1 protein encoding plant genes exert effects on cellulosic and non-cellulosic cell wall structure and cellular signaling but to establish the modes of action for any plant FAS1 protein still requires biochemical experimentation. In fungi, eubacteria and archaea, the differential presence of FAS1 proteins in closely related organisms and isolated biochemical data suggest functions in pathogenicity and symbiosis. The inter-kingdom comparison of FAS1 proteins suggests that molecular mechanisms mediating interactions between cells and their environment may have evolved at the earliest known stages of evolution.

BIGH3 Promotes Osteolytic Lesions in Renal Cell Carcinoma Bone Metastasis by Inhibiting Osteoblast Differentiation. Neoplasia 2017; 20:32-43. [PMID: 29190493 PMCID: PMC5711998 DOI: 10.1016/j.neo.2017.11.002] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2017] [Revised: 11/01/2017] [Accepted: 11/02/2017] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND: Bone metastasis is common in renal cell carcinoma (RCC), and the lesions are mainly osteolytic. The mechanism of bone destruction in RCC bone metastasis is unknown. METHODS: We used a direct intrafemur injection of mice with bone-derived 786-O RCC cells (Bo-786) as an in vivo model to study if inhibition of osteoblast differentiation is involved in osteolytic bone lesions in RCC bone metastasis. RESULTS: We showed that bone-derived Bo-786 cells induced osteolytic bone lesions in the femur of mice. We examined the effect of conditioned medium of Bo-786 cells (Bo-786 CM) on both primary mouse osteoblasts and MC3T3-E1 preosteoblasts and found that Bo-786 CM inhibited osteoblast differentiation. Secretome analysis of Bo-786 CM revealed that BIGH3 (Beta ig h3 protein), also known as TGFBI (transforming growth factor beta-induced protein), is highly expressed. We generated recombinant BIGH3 and found that BIGH3 inhibited osteoblast differentiation in vitro. In addition, CM from Bo-786 BIGH3 knockdown cells (786-BIGH3 KD) reduced the inhibition of osteoblast differentiation compared to CM from vector control. Intrafemural injection of mice with 786-BIGH3 KD cells showed a reduction in osteolytic bone lesions compared to vector control. Immunohistochemical staining of 18 bone metastasis specimens from human RCC showed strong BIGH3 expression in 11/18 (61%) and moderate BIGH3 expression in 7/18 (39%) of the specimens. CONCLUSIONS: These results suggest that suppression of osteoblast differentiation by BIGH3 is one of the mechanisms that enhance osteolytic lesions in RCC bone metastasis, and raise the possibilty that treatments that increase bone formation may improve therapy outcomes.

Melorheostosis: Exome sequencing of an associated dermatosis implicates postzygotic mosaicism of mutated KRAS. Bone 2017; 101:145-155. [PMID: 28434888 PMCID: PMC5518630 DOI: 10.1016/j.bone.2017.04.010] [Citation(s) in RCA: 31] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2017] [Revised: 04/04/2017] [Accepted: 04/10/2017] [Indexed: 10/19/2022]
Abstract
Melorheostosis (MEL) is the rare sporadic dysostosis characterized by monostotic or polyostotic osteosclerosis and hyperostosis often distributed in a sclerotomal pattern. The prevailing hypothesis for MEL invokes postzygotic mosaicism. Sometimes scleroderma-like skin changes, considered a representation of the pathogenetic process of MEL, overlie the bony changes, and sometimes MEL becomes malignant. Osteopoikilosis (OPK) is the autosomal dominant skeletal dysplasia that features symmetrically distributed punctate osteosclerosis due to heterozygous loss-of-function mutation within LEMD3. Rarely, radiographic findings of MEL occur in OPK. However, germline mutation of LEMD3 does not explain sporadic MEL. To explore if mosaicism underlies MEL, we studied a boy with polyostotic MEL and characteristic overlying scleroderma-like skin, a few bony lesions consistent with OPK, and a large epidermal nevus known to usually harbor a HRAS, FGFR3, or PIK3CA gene mutation. Exome sequencing was performed to ~100× average read depth for his two dermatoses, two areas of normal skin, and peripheral blood leukocytes. As expected for non-malignant tissues, the patient's mutation burden in his normal skin and leukocytes was low. He, his mother, and his maternal grandfather carried a heterozygous, germline, in-frame, 24-base-pair deletion in LEMD3. Radiographs of the patient and his mother revealed bony foci consistent with OPK, but she showed no MEL. For the patient, somatic variant analysis, using four algorithms to compare all 20 possible pairwise combinations of his five DNA samples, identified only one high-confidence mutation, heterozygous KRAS Q61H (NM_033360.3:c.183A>C, NP_203524.1:p.Gln61His), in both his dermatoses but absent in his normal skin and blood. Thus, sparing our patient biopsy of his MEL bone, we identified a heterozygous somatic KRAS mutation in his scleroderma-like dermatosis considered a surrogate for MEL. This implicates postzygotic mosaicism of mutated KRAS, perhaps facilitated by germline LEMD3 haploinsufficiency, causing his MEL.

Abstract
PURPOSE OF REVIEW Melorheostosis is a rare sclerosing bone dysplasia that affects both cortical bone and adjacent soft tissue structures in a sclerotomal distribution. In this review, we describe the natural history, radiological features, proposed pathogenesis, and management options for this debilitating condition. RECENT FINDINGS Since its first description in 1922, about 400 cases of melorheostosis have been reported, either as single reports or in small case series. Melorheostosis affects the appendicular skeleton more commonly than the axial skeleton and usually presents with lower limb deformity. Diagnosis is based on a combination of clinical and radiological features that help differentiate this condition from other sclerosing bone dysplasias. LEM domain-containing protein 3 (LEMD3) gene mutations have been demonstrated in several familial cases, but these have been more strongly correlated with other hereditary dysplasias, such as osteopoikilosis, and are not thought to be the causative gene for melorheostosis. The exact etiology of classic sporadically occurring melorheostosis remains unknown, with possible causes being somatic LEMD3 mutations, somatic mutations in the bone morphogenetic protein/transforming growth factor-beta pathway, mutations in multiple genes, or other non-genetic causes. Management in recent years has involved nitrogen-containing bisphosphonates in addition to traditional orthopedic surgical approaches and physical therapy. Melorheostosis may present as mixed or atypical osseous involvement in addition to the classically described "dripping candle wax" appearance of hyperostosis. Some patients may have overlap with osteopoikilosis or Buschke-Ollendorff syndrome. In the future, better characterization of genetic and developmental factors predisposing to melorheostosis may lead to the development of targeted therapy for this condition, as well as for more commonly encountered skeletal abnormalities.

Abstract
PURPOSE Transforming growth factor-β-induced protein (TGFBIp) is highly expressed in the cornea, and mutant TGFBIp induces corneal diseases. However, the function of TGFBIp in cornea epithelium is not fully investigated. Here, we tested the importance of TGFBIp in regulation of gene expression and corneal epithelial cell (CEC) activity. MATERIALS AND METHODS The effect of TGFBIp on CEC activity was analyzed by cell migration, adhesion, proliferation and wound healing assay. Analysis of gene expression was examined by western blot and quantitative reverse transcription PCR. RESULTS The results demonstrated that TGFBIp increased adhesion, migration, proliferation, and wound healing of CECs. Analysis of gene expression presented that TGFBIp-stimulated CECs exhibited increased expression of mucin family genes, such as MUC1, -4, -5AC, and -16. Furthermore, TGFBIp treatment increased the expression of MUC1, -4, -5AC, -7, and -16 in conjunctival epithelial cells. TGFBIp also increased the activity of intracellular signaling molecules ERK and AKT in CECs. Using pharmacologic inhibitors of ERK and AKT, we showed that the expression of mucin genes by TGFBIp is mediated by the activation of ERK and AKT signaling. CONCLUSION Our findings demonstrate that the locally generated TGFBIp in the cornea may contribute to wound healing of CECs by enhancing the migration, adhesion, and proliferation of CECs. In addition, our results suggest that TGFBIp has a protective effect on ocular surfaces by inducing the expression of mucin genes in corneal and conjunctival epithelial cells. These data suggest that TGFBIp is a useful therapeutic target for patients with corneal wounds.

Abstract
Transforming growth factor β-induced protein (TGFBIp) is an extracellular matrix protein whose expression in several cell types is greatly increased by TGF-β. TGFBIp is released by the human umbilical vein endothelial cells (HUVECs) and functions as a mediator of experimental sepsis. Cyclopia subternata is a medicinal plant commonly used in traditional medicine to relieve pain in biological processes. In this study, we investigated the antiseptic effects and underlying mechanisms of vicenin-2 and scolymoside, two active compounds in C. subternata against TGFBIp-mediated septic responses in HUVECs and mice. The anti-inflammatory activities of vicenin-2 or scolymoside were determined by measuring permeability, human neutrophils adhesion and migration, and activation of pro-inflammatory proteins in TGFBIp-activated HUVECs and mice. According to the results, vicenin-2 or scolymoside effectively inhibited lipopolysaccharide-induced release of TGFBIp and suppressed TGFBIp-mediated septic responses, such as hyperpermeability, adhesion and migration of leukocytes, and expression of cell adhesion molecules. In addition, vicenin-2 or scolymoside suppressed the production of tumor necrosis factor-α and interleukin 6 and activation of nuclear factor-κB and extracellular regulated kinases 1/2 by TGFBIp. Vicenin-2 or scolymoside reduced cecal ligation and puncture (CLP)-induced septic mortality and pulmonary injury. Collectively, these results indicate that vicenin-2 and scolymoside could be a potential therapeutic agent for treatment of various severe vascular inflammatory diseases via inhibition of the TGFBIp signaling pathway.

Abstract
Maintenance of haematopoietic stem cells and differentiation of committed progenitors occurs in highly specialized niches. The interactions of haematopoietic stem and progenitor cells (HSPCs) with cells, growth factors and extracellular matrix (ECM) components of the bone marrow (BM) microenvironment control homeostasis of HSPCs. We only start to understand the complexity of the haematopoietic niche(s) that comprises endosteal, arterial, sinusoidal, mesenchymal and neuronal components. These distinct niches produce a broad range of soluble factors and adhesion molecules that modulate HSPC fate during normal hematopoiesis and BM regeneration. Adhesive interactions between HSPCs and the microenvironment will influence their localization and differentiation potential. In this review we highlight the current understanding of the functional role of ECM- and adhesion (regulating) molecules in the haematopoietic niche during homeostatic and regenerative hematopoiesis. This knowledge may lead to the improvement of current cellular therapies and more efficient development of future cellular products.

Abstract
Transforming growth factor-beta-induced protein (TGFBIp) is ubiquitously expressed in the extracellular matrix (ECM) of various tissues and cell lines. Progressive accumulation of mutant TGFBIp is directly involved in the pathogenesis of TGFBI-linked corneal dystrophy. Recent studies reported that mutant TGFBIp accumulates in cells; however, the trafficking of TGFBIp is poorly understood. Therefore, we investigated TGFBIp trafficking to determine the route of its internalization and secretion and to elucidate its roles in the pathogenesis of granular corneal dystrophy type 2 (GCD2). Our data indicate that newly synthesized TGFBIp was secreted via the endoplasmic reticulum/Golgi-dependent secretory pathway, and this secretion was delayed in the corneal fibroblasts of patients with GCD2. We also found that TGFBIp was internalized by caveolae-mediated endocytosis, and the internalized TGFBIp accumulated after treatment with bafilomycin A1, an inhibitor of lysosomal degradation. In addition, the proteasome inhibitor MG132 inhibits the endocytosis of TGFBIp. Co-immunoprecipitation revealed that TGFBIp interacted with integrin αVβ3. Moreover, treatment with arginine-glycine-aspartic acid (RGD) tripeptide suppressed the internalization of TGFBIp. These insights on TGFBIp trafficking could lead to the identification of novel targets and the development of new therapies for TGFBI-linked corneal dystrophy.

Abstract
Transforming growth factor-β-induced protein (TGFBIp) is an extracellular matrix protein that has a role in a wide range of pathological conditions. However, the role of TGFBIp signaling in lymphangiogenesis is poorly understood. The purpose of this study was therefore to analyze the effects of TGFBIp on lymphangiogenesis and determine whether TGFBIp-related lymphangiogenesis is important for the metastasis of tumor cells. TGFBIp increased adhesion, migration, and morphologic differentiation of human lymphatic endothelial cells (LECs), consistent with an increase in lymphatic vessel sprouting in a three-dimensional lymphatic ring assay. TGFBIp also induced phosphorylation of intracellular signaling molecules SRC, FAK, AKT, JNK and ERK. TGFBIp-induced lymphatic vessel sprouting was inhibited by addition of anti-integrin β3 antibody and pharmacologic inhibitors of FAK, AKT, JNK or ERK. TGFBIp increased both CCL21 expression in LECs, a chemokine that actively recruits tumor cells expressing the cognate chemokine receptors to lymphatic vessels and LEC permeability by inducing the dissociation of VE-cadherin junctions between LECs via the activation of SRC signaling. In vivo, inhibition of TGFBIp expression in SW620 cancer cells dramatically reduced tumor lymphangiogenesis and metastasis. Collectively, our findings demonstrate that TGFBIp is a lymphangiogenic factor contributing to tumor dissemination and represents a potential target to inhibit metastasis.

Abstract
AIM Sepsis is a systemic inflammatory response syndrome resulting from a microbial infection. Transforming growth factor β-induced protein (TGFBIp) is an extracellular matrix protein expressed by human endothelial cells and platelets that induces sepsis through interaction with integrin αvβ5. The aim of this study was to investigate the role of TGFBIp in vascular permeability and the underlying mechanisms using TGFBIp-neutralizing antibody. METHODS Mice were subjected to caecal ligation and puncture (CLP) with or without neutralizing anti-TGFBIp antibody (300 μg kg(-1), intravenously). Wild-type or integrin β5-null mice received TGFBIp (0.1 mg kg(-1), intravenously) or were subjected to CLP. Human umbilical vein endothelial cells were exposed to lipopolysaccharide (100 ng mL(-1)) with or without neutralizing anti-TGFBIp antibody (50 μg mL(-1)). RESULTS Administration of neutralizing anti-TGFBIp antibody in mice attenuated CLP-induced secretion of TGFBIp, leucocyte migration and vascular permeability and reduced septic mortality. Injected TGFBIp did not enhance vascular barrier permeability or leucocyte migration in β5-null mice. Finally, neutralizing anti-TGFBIp antibody inhibited the specific interactions between TGFBIp and its receptor, integrin αvβ5. CONCLUSION Our findings demonstrate that treatment with a TGFBIp-neutralizing antibody can ameliorate the deleterious effects of sepsis.

Abstract
A rare disease afflicts less than 200,000 individuals, according to the National Organization for Rare Diseases (NORD) of the United States. Over 6,000 rare disorders affect approximately 1 in 10 Americans. Rare genetic bone disorders remain the major causes of disability in US patients. These rare bone disorders also represent a therapeutic challenge for clinicians, due to lack of understanding of underlying mechanisms. This systematic review explored current literature on therapeutic directions for the following rare genetic bone disorders: fibrous dysplasia, Gorham-Stout syndrome, fibrodysplasia ossificans progressiva, melorheostosis, multiple hereditary exostosis, osteogenesis imperfecta, craniometaphyseal dysplasia, achondroplasia, and hypophosphatasia. The disease mechanisms of Gorham-Stout disease, melorheostosis, and multiple hereditary exostosis are not fully elucidated. Inhibitors of the ACVR1/ALK2 pathway may serve as possible therapeutic intervention for FOP. The use of bisphosphonates and IL-6 inhibitors has been explored to be useful in the treatment of fibrous dysplasia, but more research is warranted. Cell therapy, bisphosphonate polytherapy, and human growth hormone may avert the pathology in osteogenesis imperfecta, but further studies are needed. There are still no current effective treatments for these bone disorders; however, significant promising advances in therapeutic modalities were developed that will limit patient suffering and treat their skeletal disabilities.

Abstract
RATIONALE Sepsis is a systemic inflammatory condition resulting from bacterial infections; it has a high mortality rate and limited therapeutic options. Despite extensive research into the mechanisms driving bacterial sepsis, the target molecules controlling vascular leakage are still largely unknown. Transforming growth factor β-induced protein (TGFBIp) is an extracellular matrix protein expressed in several cell types, which is known to interact with integrins. OBJECTIVES The aim of this study was to determine the roles of TGFBIp in vascular proinflammatory responses, and the mechanisms of action driving these responses. METHODS Circulating levels of TGFBIp were measured in patients admitted to the hospital with sepsis, severe sepsis, and septic shock and in cecal ligation and puncture (CLP)-induced septic mice. Effects of TGFBIp knockout on CLP-induced septic mortality and effects of TGFBIp on multiple vascular proinflammatory responses were determined. MEASUREMENTS AND MAIN RESULTS Circulating levels of TGFBIp were significantly elevated compared with healthy controls, and were strongly correlated with disease severity. High blood TGFBIp levels were also observed in CLP-induced septic mice. The absence of the TGFBIp gene in mice attenuated CLP-induced sepsis. TGFBIp enhanced vascular proinflammatory responses including vascular permeability, adhesion and migration of leukocytes, and disruption of adherence junctions through interacting with integrin αvβ5. CONCLUSIONS Collectively, our findings demonstrate that the TGFBIp-αvβ5 axis can elicit severe inflammatory responses, suggesting it to be a potential target for development of diagnostics and therapeutics for sepsis.

Abstract
Introduction: Melorheostosis(synonyms: candle bone disease, melting wax syndrome, Leri disease) is a rare chronic bone disorder, first described in 1922 by Leri and Joanny. Men and women are equally affected, and no hereditary features have been discovered. Onset is insidious, and most common symptom is pain. Most common part of bone is diaphysis of the long bone of lower limb rarely the axial skeleton. Classical radiological appearance of ’flowing hyperosteosis’ resembling hardened wax that has dripped down the side of a candle. Case Report: A 35 years old woman presented with left leg pain with mild swelling and limitation of knee movement. On examination non tender bony heard swelling, hyperpigmented and restriction of knee movement present. Plain radiographs showed extensive, dense, undulating or irregular cortical hyperostosis, resembling candle wax, extending along the length of bone. Pamidronate as well asanalgesic were given to the patient. Physiotherepy started for the deformity. Conclusion: Routine laboratory findings usually are normal. The exact cause remain unclear. There is no definite treatment available for this disease. Only symptomatic treatment improve the condition of the patients, more fruitful result obtain with pamidronate and physiotherapy.

Abstract
Periostin (Postn) and transforming growth factor β-induced protein (TGFβIp) are two closely related extracellular matrix (ECM) proteins predominantly distributed in collagen-rich connective tissues submitted to mechanical strain, including bone and more specifically the periosteum. We have investigated the expression of Postn and TGFβIp mRNA by primary osteoblasts isolated from mouse periosteum and calvaria, or by the osteoblast-like MC3T3-E1 cell line, and by osteoclasts from mouse long bones differentiated in vitro. Secretion of Postn was measured with a specific ELISA. Postn and TGFβIp mRNA were concomitantly expressed in all three osteoblast models all along the differentiation process in a time-dependent manner. Both Postn and TGFβIp transcripts appeared early in osteoblast differentiation, and their expression increased 3-10 times in mature osteoblast cells. Expression decreased after differentiation was achieved and when the cultures mineralised. ELISA for secreted Postn showed a similar pattern. When MC3T3-E1 cells were treated with TGF-β, Postn and TGFβIp mRNA expression and secretion were stimulated, whereas 1.25(OH)(2)D(3) had no detectable effect. Osteoclasts also expressed both Postn and TGFβIp during in vitro differentiation. Expression of both Postn and TGFβIp peaks in the early phases of osteoblast differentiation, and decreases later at the start of mineralisation. A novel finding is that Postn and TGFβIp are expressed by osteoclasts in vitro. Therefore Postn and TGFβIp proteins are potential biomarkers of early osteoblast differentiation and new bone formation.

Abstract
We present a case report of melorheostosis with the novel radiographic finding of underlying cortical resorption. A number of radiographic patterns of melorheostosis have been described; however, the combination of new bone formation and resorption of the original cortex appears unique. Although the presence of underlying lysis has been postulated in published studies, direct radiographic evidence of bony resorption in melorheostosis has not been reported. These findings can be subtle and might go unnoticed using standard imaging. An in-depth review of the radiographic features is presented, including multimodality imaging with magnetic resonance imaging and computed tomography.

Abstract
Transforming growth factor-beta induced (TGFBI) and periostin are two closely related proteins in structure as well as in function. A previous study found that periostin positively regulates bone size. Here, we hypothesize that TGFBI has a similar function in bone development. To test this hypothesis, we employed TGFBI-deficient mice, which were generated by targeted disruption of the TGFBI gene. We bred these mice with C57BL/6J mice to generate homozygous TGFBI-deficient (TGFBI(-/-)) mice and homozygous wild-type littermates. All mice were raised to 12 weeks of age. Bone mass parameters were determined by PIXImus and micro-CT, bone strength parameters by three-point bending, and bone formation and resorption parameters by histomorphometry. We found that targeted disruption of TGFBI led to reduced body size, bone mass, bone size, and bone strength. This indicates that, like periostin, TGFBI also positively regulates bone size and that changes in bone size affect bone strength. Furthermore, there was also a significant decrease in periosteal, but not endosteal, bone formation rate of cortical bone in TGFBI(-/-) mice, suggesting that the observed effect of TGFBI on bone mass and bone size was largely caused by the effect of TGFBI on periosteal bone formation.

Abstract
It is known that VEGF receptors (VEGFR) and integrins interact with each other to regulate angiogenesis. We reported previously that the fasciclin 1 (FAS1) domain-containing protein, TGFBIp/βig-h3 (TGF-β-induced protein) is an angiogenesis regulator that inhibits both endothelial cell migration and growth via αvβ3 integrin. In an attempt to target the interaction between VEGFR-2 and αvβ3 integrin, we determined whether the FAS1 domain region of TGFBIp/βig-h3 (FAS1 domain protein) can block the interaction between the two receptors, leading to the suppression of angiogenesis. In this study, we showed that FAS1 domain protein inhibits VEGF165-induced endothelial cell proliferation and migration via αvβ3 integrin, resulting in the inhibition of VEGF165-induced angiogenesis. We also defined a molecular mechanism by which FAS1 domain protein blocks the association between αvβ3 integrin and VEGFR-2, showing that it binds to αvβ3 integrin but not to VEGFR-2. Blocking the association of these major angiogenic receptors with FAS1 domain protein inhibits signaling pathways downstream of VEGFR-2. Collectively, our results indicate that FAS1 domain protein, in addition to its inhibitory effect on αvβ3 integrin-mediated angiogenesis, also inhibits VEGF165-induced angiogenesis. Thus, FAS1 domain protein can be further developed into a potent anticancer drug that targets two principal angiogenic pathways.

Abstract
Background Transforming growth factor β induced (TGFBI) product, an extracellular matrix (ECM) protein, has been implicated as a putative tumor suppressor in recent studies. Our previous findings revealed that expression of TGFBI gene is down-regulated in a variety of cancer cell lines and clinical tissue samples. In this study, ectopic expression of TGFBI was used to ascertain its role as a tumor suppressor and to determine the underlying mechanism of mesothelioma and breast cancer. Methods Cells were stably transfected with pRc/CMV2-TGFBI and pRc/CMV2-empty vector with Lipofectamine Plus. Ectopic expression of TGFBI was quantified by using quantitative PCR and Western-blotting. Characterization of cell viability was assessed using growth curve, clonogenic survival and soft agar growth. The potential of tumor formation was evaluated by an in vivo mouse model. Cell cycle was analyzed via flow cytometry. Expressions of p21, p53, p16 and p14 were examined using Western-blotting. Senescent cells were sorted by using a Senescence β-Galactosidase Staining Kit. Telomerase activity was measured using quantitative telomerase detection kit. Results In this study, an ectopic expression of TGFBI in two types of cancer cell lines, a mesothelioma cell line NCI-H28 and a breast cancer cell line MDA-MB-231 was found to have reduced the cellular growth, plating efficiency, and anchorage-independent growth. The tumorigenicity of these cancer cell lines as determined by subcutaneous inoculation in nude mice was similarly suppressed by TGFBI expression. Likewise, TGFBI expression reduced the proportion of S-phase while increased the proportion of G1 phase in these cells. The redistribution of cell cycle phase after re-expression of TGFBI was correspondent with transiently elevated expression of p21 and p53. The activities of senescence-associated β-galactosidase and telomerase were enhanced in TGFBI-transfected cells. Conclusion Collectively, these results imply that TGFBI plays a suppressive role in the development of mesothelioma and breast cancer cells, possibly through inhibitions of cell proliferation, delaying of G1-S phase transition, and induction of senescence.

Abstract
In this paper, we report the clinical and molecular features of the distinct TGFBI (human transforming growth factor β-induced, OMIM No. 601692) gene-linked corneal dystrophy. Altogether, five pedigrees and ten unrelated individuals diagnosed as corneal dystrophy were recruited. Peripheral venous DNA was extracted, and then amplified by polymerase chain reaction (PCR) and scanned for mutation by single-stranded conformation polymorphism (SSCP). Direct DNA sequencing was used to analyze the mutations of the TGFBI gene. In our study, thirty patients from five pedigrees and ten sporadic patients were diagnosed as four TGFBI gene-linked corneal dystrophies of granular corneal dystrophy type I (GGCD I), Avellino corneal dystrophy (ACD), lattice corneal dystrophy type I (LCD I), and lattice corneal dystrophy type IIIA (LCD IIIA), and in total, seven disease-causing mutations, namely R555W, A546D, A546T, and T538P mutations in exon 12, R124H and R124C mutations in exon 4, and P501T mutation in exon 11, were identified, while four polymorphisms of V327V, L472L, F540F, and 1665-1666insC were screened in exons 8, 11, and 12. The study ascertained the tight genotype-phenotype relationship and confirmed the clinical and genetic features of four TGFBI gene-linked corneal dystrophies.

Abstract
Transforming growth factor-beta-induced protein (TGFBIp)/beta ig-h3 is a 68-kDa extracellular matrix protein that is functionally associated with the adhesion, migration, proliferation, and differentiation of various cells. The presence of TGFBIp in platelets led us to study the role of this protein in the regulation of platelet functions. Upon activation, platelet TGFBIp was released and associated with the platelets. TGFBIp mediates not only the adhesion and spread of platelets but also activates them, resulting in phosphatidylserine exposure, alpha-granule secretion, and increased integrin affinity. The fasciclin 1 domains of TGFBIp are mainly responsible for the activation of platelets. TGFBIp promotes thrombus formation on type I fibrillar collagen under flow conditions in vitro and induces pulmonary embolism in mice. Moreover, transgenic mice, which have approximately a 1.7-fold greater blood TGFBIp concentration, are significantly more susceptible to collagen- and epinephrine-induced pulmonary embolism than wild-type mice. These results suggest that TGFBIp, a human platelet protein, plays important roles in platelet activation and thrombus formation. Our findings will increase our understanding of the novel mechanism of platelet activation, contributing to a better understanding of thrombotic pathways and the development of new antithrombotic therapies.

Abstract
Melorheostosis is a rare disorder marked by increased bony sclerosis on radiographs. In addition to bone changes, the skin and soft tissues overlying affected bone often demonstrate increased fibrosis, which can create joint contracture. These can all affect surgical planning for a patient with melorheostosis. This article reviews the literature and describes the surgical intervention and 4-year follow-up of a 10-year-old boy with melorheostosis.

Abstract
The extracellular matrix protein Tgfbi has been shown to localise to myotendinous junctions in mouse and postulated to interact with the transmembrane protein Integrin alpha7beta1, which, in parallel with the Dystrophin-associated protein complex, is critical for linkage between the extracellular matrix and the cytoskeleton of muscle fibres. Here we use a GFP-tagged form of Tgfbi to analyse its distribution in the developing skeletal muscle of the zebrafish embryos and antisense morpholino oligonucleotides to investigate the function of the endogenous protein. We find that although tagged Tgfbi accumulates at the myosepta, the attachment of muscle fibres to the myosepta is established and maintained normally in morphant embryos; however, the fibres show a marked reduction in their growth and a disruption of their myofibril bundles.

Abstract
Osteoporosis (OP) is a common age-related systemic skeletal disease, with a strong genetic component, characterised by loss of bone mass and strength, which leads to increased bone fragility and susceptibility to fracture. Although some progress has been made in identifying genes that may contribute to OP disease, much of the genetic component of OP has yet to be accounted for. Therefore, to investigate the molecular basis for the changes in bone causally involved in OP and fragility fracture, we have used a microarray approach. We have analysed altered gene expression in human OP fracture bone by comparing mRNA in bone from individuals with fracture of the neck of the proximal femur (OP) with that from age-matched individuals with osteoarthritis (OA), and control (CTL) individuals with no known bone pathology. The OA sample set was included because an inverse association, with respect to bone density, has been reported between OA and the OP individuals. Compugen H19K oligo human microarray slides were used to compare the gene expression profiles of three sets of female samples comprising, 10 OP-CTL, 10 OP-OA, and 10 OA-CTL sample pairs. Using linear models for microarray analysis (Limma), 150 differentially expressed genes in OP bone with t scores >5 were identified. Differential expression of 32 genes in OP bone was confirmed by real time PCR analysis (p<0.01). Many of the genes identified have known or suspected roles in bone metabolism and in some cases have been implicated previously in OP pathogenesis. Three major sets of differentially expressed genes in OP bone were identified with known or suspected roles in either osteoblast maturation (PRRX1, ANXA2, ST14, CTSB, SPARC, FST, LGALS1, SPP1, ADM, and COL4A1), myelomonocytic differentiation and osteoclastogenesis (TREM2, ANXA2, IL10, CD14, CCR1, ADAM9, CCL2, CTGF, and KLF10), or adipogenesis, lipid and/or glucose metabolism (IL10, MARCO, CD14, AEBP1, FST, CCL2, CTGF, SLC14A1, ANGPTL4, ADM, TAZ, PEA15, and DOK4). Altered expression of these genes and others in these groups is consistent with previously suggested underlying molecular mechanisms for OP that include altered osteoblast and osteoclast differentiation and function, and an imbalance between osteoblastogenesis and adipogenesis.

Abstract
betaig-h3 is a TGF-beta-induced extracellular matrix protein which is expressed in many tissues including bones and cartilages. In previous reports, we showed that betaig-h3 mediates cell adhesion and migration and, especially in bones, negatively regulates the mineralization in the end stage of endochondral ossification. Here, to elucidate the expression pattern and role of betaig-h3 in chondrocyte differentiation, ATDC5 chondrocytes and embryonic and postnatal mice were used for in vitro differentiation studies and in vivo studies, respectively. betaig-h3 was strongly induced by the treatment of TGF-beta1 and the expression level of betaig-h3 mRNA and protein were highly expressed in the early stages of differentiation but decreased in the late stages in ATDC5. Furthermore, the patterns of TGF-beta1, -beta2, and -beta3 mRNA expression were concurrent with betaig-h3 in ATDC5. betaig-h3 was deeply stained in perichondrium (PC), periosteum (PO), and prehypertrophic chondrocytes (PH) through the entire period of endochondral ossification in mice. betaig-h3 was mainly expressed in PC and PH at embryonic days and obviously in PH in postnatal days. These results suggest that betaig-h3 may play a critical role as a regulator of chondrogenic differentiation in endochondral ossification.

Abstract
Monocyte recruitment from the blood in response to chemoattractant gradients is a key phenomenon in inflammation. Various extracellular matrix proteins, at the site of inflammation, have chemoattractant activity and mediate monocyte adhesion and migration as ligands of integrins. In this report, we demonstrate that transforming growth factor-beta-induced gene product (betaig-h3/TGFBIp), as an extracellular matrix protein, mediates monocytes adhesion under both static and flow conditions mainly through integrin alphaMbeta2. Fasciclin 1 domains of betaig-h3/TGFBIp are responsible for the interaction with integrin alphaMbeta2, not only enhances monocyte migration in both chemotactic and haptotactic manners but also mediates their transendothelial migration and subendothelial matrix invasion. These activities are also mediated through integrin alphaMbeta2. Intraperitoneal injection of betaig-h3/TGFBIp promotes the recruitment of monocytes but not neutrophils. Our results demonstrate that betaig-h3/TGFBIp produced at inflammatory sites is a novel chemoattractant for monocytes and interacts with integrin alphaMbeta2 to serve as a substrate for their migration, suggesting that betaig-h3/TGFBIp plays an important role in inflammation.

Abstract
OBJECTIVE To delineate the expression of transforming growth factor beta-inducible gene h3 (betaIG-H3) in rheumatoid synovitis and to determine the regulatory role of betaIG-H3 in the adhesion and migration of fibroblast-like synoviocytes (FLS). METHODS Synovial tissue was obtained from patients with rheumatoid arthritis (RA) during joint replacement surgery, and FLS were isolated using enzymatic treatment. Immunohistochemical staining was performed to show the expression of betaIG-H3 within rheumatoid synovium. Synthesis of betaIG-H3 from FLS was determined by semiquantitative reverse transcription-polymerase chain reaction, Western blot analysis, and enzyme-linked immunosorbent assay. Cell adhesion and migration assays were performed using the YH18 peptide in the fourth fas-1 domain of betaIG-H3 and function-blocking antibodies to integrins. RESULTS Expression of betaIG-H3 was up-regulated in RA synovial tissue compared with synovial tissue from patients with osteoarthritis. FLS isolated from RA synovial tissue constitutively produced betaIG-H3, which was up-regulated by transforming growth factor beta1, interleukin-1beta, and tumor necrosis factor alpha. Although FLS expressed a variety of integrins, betaIG-H3 mediated adhesion and migration of FLS through interaction with alpha v beta3 integrin. Cytokines failed to affect the betaIG-H3-mediated adhesion. However, migration of FLS guided by betaIG-H3 was enhanced by interferon-gamma and platelet-derived growth factor type BB. The YH18 peptide in the fourth fas-1 domain of betaIG-H3 inhibited adhesion and migration in a dose-dependent manner. CONCLUSION The results suggest that betaIG-H3, which is abundantly expressed in RA synovial tissue, plays a regulatory role in chronic destructive inflammation through the modulation of the adhesion and migration of FLS. This finding indicates the relevance of betaIG-H3 and alpha v beta3 integrin-interacting motifs as potential therapeutic targets in this disease.

Abstract
Although the U.S. Environmental Protection Agency has restricted the industrial use of regulated forms of asbestos in the United States since the early 1970s, environmental exposure to asbestos remains a health concern in the United States and is a significant health issue among developing countries. Exposure to asbestos is associated with chronic pulmonary diseases and cancer of the lung, pleura, and peritoneum. The mechanism of fiber carcinogenesis is far from clear and is likely to be complex, depending on fiber dimensions, surface properties, and physical durability. The induction of reactive oxygen and nitrogen species upon phagocytosis of fibers plays an important role in fiber genotoxicity. The beta igH3, a secreted protein induced by the transforming growth factor-beta and essential for cell adhesion, is downregulated in asbestos-induced tumorigenic human bronchial epithelial cells. Ectopic expression of the beta igH3 gene abrogates the tumorigenic phenotype and suggests that the gene plays a causal role in fiber carcinogenesis. A better understanding of the carcinogenic mechanism of asbestos and other mineral fibers will provide useful information on interventional and preventive measures for asbestos-mediated diseases such as human pleural and peritoneal mesotheliomas.

Abstract
Gene silencing by CpG island methylation in the promoter region is one of the mechanisms by which tumor suppressor genes are inactivated in human cancers. It has been shown previously that Betaig-h3 gene, which encodes an extracellular matrix protein involved in cell adhesion and tumorigenesis, is down-regulated or silenced in a variety of human cancer cell lines. To unravel the underlying molecular mechanism(s) for this phenomenon, DNA methylation patterns of Betaig-h3 CpG island were examined in normal, immortalized, and cancer cell lines derived from lung, prostate, mammary, and kidney. A good correlation was observed between promoter hypermethylation and lost expression of Betaig-h3 gene, which was supported by the data that demethylation of promoter by 5-aza-2'-deoxycytidine reactivated Betaig-h3 and restored its expression in Betaig-h3-silenced tumor cell lines. This result was further substantiated by a luciferase reporter assay, showing the restoration of promoter activities and increased response to transforming growth factor-beta treatment in Betaig-h3-negative 293T cells when transfected with unmethylated Betaig-h3 promoter. In contrast, activity of Betaig-h3 promoter was completely inactivated by in vitro methylation. Furthermore, CpG methylation of Betaig-h3 promoter was also shown in primary lung tumors that expressed decreased level of Betaig-h3 protein. These results suggest that promoter methylation plays a critical role in promoter silencing of the Betaig-h3 gene in human tumor cells.

Abstract
Epithelial basement membrane corneal dystrophy (EBMD), also known as Cogan microcystic epithelial dystrophy or map-dot-fingerprint dystrophy, is a common bilateral epithelial dystrophy. Usually, this disease is not considered to be inherited although several families with autosomal dominant inheritance have been described. We report the analysis of two families with an autosomal dominant pattern of inheritance as well as the analysis of single affected individuals; we identified two different point mutations in the TGFBI/BIGH3 genes, genes known to be associated with other corneal dystrophies. This is the first report of a molecular mutation in individuals with EBMD and it increases the spectrum of mutations in the TGFBI/BIGH3 gene. Based on our screening, up to 10% of EBMD patients could have a mutation in this gene.
