Successful clinical repair of non-healing skeletal defects requires the use of bone substitutes with robust bone inductivity and excellent biomechanical stability. Thus, three-dimensionally functionalised porous calcium phosphate-Ti6Al4V (CaP-Ti) hybrids were produced by perfusion electrodeposition, and the in vitro and in vivo biological performances were evaluated using human periosteum derived cells (hPDCs). By applying various current densities at the optimised deposition conditions, CaP coatings with sub-micrometer to nano-scale porous crystalline structures and different ion dissolution kinetics were deposited on the porous Ti6Al4V scaffolds. These distinctive physicochemical properties caused a significant impact on in vitro proliferation, osteogenic differentiation, and matrix mineralisation of hPDCs. This includes a potential role of hPDCs in mediating osteoclastogenesis for the resorption of CaP coatings, as indicated by a significant down-regulation of osteoprotegerin (OPG) gene expression and by the histological observation of abundant multi-nucleated giant cells near to the coatings. By subcutaneous implantation, the produced hybrids induced ectopic bone formation, which was highly dependent on the physicochemical properties of the CaP coating (including the Ca(2+) dissolution kinetics and coating surface topography), in a cell density-dependent manner. This study provided further insight on stem cell-CaP biomaterial interactions, and the feasibility to produced bone reparative units that are predictively osteoinductive in vivo by perfusion electrodeposition technology.

Bone sialoprotein (BSP) is a small, highly posttranslationally modified integrin binding protein found in the mineral compartment of developing bone. The recent discovery that BSP can be detected in a variety of human cancers, particularly those that metastasize preferentially to the skeleton, shed light on potential new biological functions for this protein. The demonstration of a positive association between BSP expression in primary breast tumors and the development of bone metastases suggests that this glycoprotein could play a role in the selective implantation of breast cancer cells in bone. BSP is also expressed in most lung and prostate cancers as well as in multiple myeloma, three other osteotropic malignancies. Because thyroid carcinoma also metastasizes preferentially to the skeleton, we decided to look at the expression of BSP in a collection of 145 thyroid malignant lesions including 24 follicular thyroid carcinomas (FTCs), 55 papillary thyroid carcinomas (PTCs), 19 medullary thyroid carcinomas (MTCs), 23 anaplastic carcinomas (ACs), and 24 poorly differentiated carcinomas (PDCs). BSP expression was evaluated by immunoperoxidase technique using two specific polyclonal antibodies. Most of the thyroid carcinomas (72%) examined expressed high levels of BSP. Expression of BSP was significantly lower in FTCs and MTCs compared with PDCs, which are more aggressive (p = 0.0009 and 0.0003, respectively). Our study demonstrates for the first time that ectopic BSP expression is a common feature of thyroid cancer. The prognostic value of BSP detection in thyroid adenocarcinoma and the potential role of BSP in the propension of this type of cancer to metastasize to bone are currently under investigation.

The callipyge (CLPG) phenotype is an inherited skeletal muscle hypertrophy described in sheep. It is characterized by an unusual mode of inheritance ("polar overdominance") in which only heterozygous individuals having received the CLPG mutation from their father (+(MAT)/CLPG(PAT)) express the phenotype . +(MAT)/CLPG(PAT) individuals are born normal and develop the muscular hypertrophy at approximately 1 month of age. The CLPG mutation was identified as an A to G transition in a highly conserved dodecamer motif located between the imprinted DLK1 and GTL2 genes . This motif is thought to be part of a long-range control element (LRCE) because the CLPG mutation was shown, in postnatal skeletal muscle, to enhance the transcript levels of the DLK1, PEG11, GTL2, and MEG8 genes in cis without altering their imprinting status . As a result, the +(MAT)/CLPG(PAT) individuals have a unique expression profile thought to underlie the callipyge phenotype: an overexpression of the paternally expressed protein encoding DLK1 (Figure 1A) and PEG11 transcripts in the absence of an overexpression of the maternally expressed noncoding GTL2 and MEG8 transcripts . However, the way in which this distinct expression profile causes the callipyge muscular hypertrophy has remained unclear. Herein, we demonstrate that the callipyge phenotype is perfectly correlated with ectopic expression of DLK1 protein in hypertrophied muscle of +(MAT)/CLPG(PAT) sheep. We demonstrate the causality of this association by inducing a generalized muscular hypertrophy in transgenic mice that express DLK1 in skeletal muscle. The absence of DLK1 protein in skeletal muscle of CLPG/CLPG animals, despite the presence of DLK1 mRNA, supports a trans inhibition mediated by noncoding RNAs expressed from the maternal allele.

Background Ectopic hormone-secreting pheochromocytomas <br />are rare; only case reports exist in the literature. This <br />condition has been linked with increased malignancy, <br />familial syndromes, and ACTH secretion. We wanted to <br />test these hypotheses and shed light on the nature of ectopic <br />hormone-secreting pheochromocytomas. <br />Methods This is a multicenter (francophone) observational <br />study. Inclusion was based upon abnormal preoperative <br />hormone tests in patients with pheochromocytoma <br />that normalized after removal of the tumor. Where <br />possible, immunohistochemistry was performed to confirm <br />that ectopic secretion came from the tumor. <br />Results Sixteen cases were found: nine female and seven <br />male patients. Median age was 50.5 (range 31–89) years. <br />Most presented with hypertension, diabetes, or cushingoid <br />features. Ten patients had specific symptoms from the <br />ectopic hormone secretion. Two had a familial syndrome. <br />Of eight patients with excess cortisol secretion, three died <br />as a result of the tumor resection: two had pheochromocytomas[ <br />15 cm and their associated cortisol hypersecretion <br />complicated their postoperative course. The other died <br />from a torn subhepatic vein. The 13 survivors did not <br />develop any evidence of malignancy during follow-up <br />(median 50 months). Symptoms from the ectopic secretion <br />resolved after removal of the tumor. Immunohistochemistry <br />was performed and was positive in eight tumors: five <br />ACTH, three calcitonins, and one VIP. <br />Conclusions Most pheochromocytomas with ectopic <br />secretion are neither malignant nor familial. Most ectopic <br />hormone-secreting pheochromocytoma cause hypercortisolemia. <br />Patients with a pheochromocytoma should be <br />worked up for ectopic hormones, because removal of the <br />pheochromocytoma resolves those symptoms. Associated <br />cortisol secretion needs careful attention. [less ▲]

Ureteral ectopia is a congenital abnormality in which one or both ureters does not open into the bladder. This is the most common cause of urinary incontinence in the immature bitch, but is rarely diagnosed in the male dog. Some breeds are predisposed (Siberian Husky, Labrador, Golden Retriever). Typical clinical signs are a continuous (but sometimes intermittent) leakage of urine since birth, although micturition can be normal. Other associated congenital abnormalities can be present (hydronephrosis, double vagina, cryptorchidism). Diagnostic techniques include excretory urography coupled with a pneumocystography, vaginourethrography, cystoscopy, vaginoscopy, and ultrasonography. Ectopic ureters can be unilateral (most commonly) or bilateral, and they are either intramural or extramural. Surgical correction is the treatment of choice. After a successful surgery, some patients can still show some degree of incontinence, due to the presence of urethral sphincter mechanism incompetence. This residual incontinence can be resolved in the majority of the cases with the use of alpha-adrenergic agents. [less ▲]
