Abstract
Tibial dyschondroplasia (TD) is an intractable avian bone disease that causes severe poultry economic losses. The pathogenicity of TD is unknown. Therefore, TD disease has not been evacuated yet. Based on continuous research findings, we have gone through the molecular and cellular insight into the TD and proposed possible pathogenicity for future studies. Immunity and angiogenesis-related genes expressed in the erythrocytes of chicken, influenced the apoptosis of chicken chondrocytes to cause TD. TD could be defined as the irregular, unmineralized and un-vascularized mass of cartilage, which is caused by apoptosis, degeneration and insufficient blood supply at the site of the chicken growth plate. The failure of angiogenesis attributed improper nutrients supply to the chondrocytes; ultimately, bone development stopped, poor calcification of cartilage matrix, and apoptosis of chondrocytes occurred. Recent studies explore potential signaling pathways that regulated TD in broiler chickens, including parathyroid hormone-related peptide (PTHrP), transforming growth factor β (TGF- β)/bone morphogenic proteins (BMPs), and hypoxia-inducible factor (HIF). Several studies have reported many medicines to treat TD. However, recently, rGSTA3 protein (50 μg·kg-1) is considered the most proper TD treatment. The present review has summarized the molecular and cellular insight into the TD, which will help researchers in medicine development to evacuate TD completely.

Abstract
Excessive intake of fluoride inhibits bone growth in both humans and animals. It is unknown whether fluoride acts directly on the growth plate to inhibit longitudinal bone growth, and its mechanism of action has not been elucidated. In this study, we used an organ culture system and SW1353 cells to evaluate the effects of fluoride on endochondral ossification. Neonatal rat metatarsal bones were dissected and cultured with or without fluoride for 7 days. The total length and width of the metatarsal rudiments and the length of the calcification zone were measured. Chondrocyte proliferation, differentiation, and apoptosis were analyzed by immunohistochemistry and TUNEL assay in sectioned bones. The apoptosis was detected by flow cytometry, and the expression of apoptosis-related proteins Bax, Bcl-2, and Caspase-3 were detected by western blotting in SW1353 cells. Linear measurements demonstrated that fluoride induced a biphasic effect on longitudinal bone growth in organ culture, with a significant growth inhibition at a high concentration (10-4 M) and a stimulatory action at low concentration (10-6 M) of fluoride. Histomorphometrical analysis of growth plate from fluoride-exposed metatarsal rudiments showed a significant reduction in the height of the proliferative and hypertrophic chondrocyte zones. Analysis of the Col2α1 and Col10α1 expression by immunohistochemistry revealed fluoride-suppressed metatarsal growth plate chondrocyte proliferation and differentiation. In addition, fluoride increased the number of apoptotic chondrocytes in the metatarsal growth plate. Western blotting showed an up-regulated expression of Caspase-3 and Bax and down-regulated expression of anti-apoptotic protein Bcl-2 after treatment with 5 × 10-4 M fluoride in SW1353 cells. Our findings indicated that fluoride inhibited longitudinal bone growth by acting directly at the growth plate in cultured neonatal rat metatarsal bones. Such growth inhibition was mediated by suppressing proliferation and differentiation, increasing apoptosis of resting chondrocytes and causing premature cell senescence in the growth plate.

Camelina sativa cake for broiler chickens: effects of increasing dietary inclusion on clinical signs of toxicity, feed disappearance, and nutrient digestibility. Transl Anim Sci 2020; 4:txaa029.

Abstract
The effect of feeding diets with increasing dietary inclusions of Camelina sativa cake (CC; 22% ether extract, 34% crude protein) on safety, feed disappearance, and nutrient digestibility was evaluated in a 42-day (d) broiler study. Day-old male chicks (Ross 308; n = 744) were divided among 24 test cages in a randomized complete block design with six replicate cages per dietary regimen. Dietary regimens consisted of feeding test diets containing 0, 8, 16, or 24% CC over three growth phases of 2-week duration each. Diets fed from d 14-21 included an indigestible marker. Pen body weight, feed added, and leftover orts for each phase were measured on d 0, 14, 28, and 42 to calculate average daily feed disappearance, average daily weight gain, and gain-to-feed ratio. On d 14, 28, and 42, three broilers per test cage were euthanized by intravenous injection. A gross post mortem examination was conducted and select organs were weighed. Blood was drawn from broilers removed on d 42 to measure serum parameters. Excreta from d 19 to 21 and ileal digesta (10 birds per cage) on d 21 were collected to yield a single pooled sample of each per test cage. Dietary CC inclusion up to 24% did not affect broiler mortality or the incidence of abnormal gross findings. Differences (P < 0.05) in serum levels of P, uric acid, T3, and T4 are explained by differential digestible nutrient intake among broilers fed increasing CC inclusion levels. Organ weight as proportion of body weight was not affected by treatment, except for pancreas on d 28 and 42, which both linearly increased (P < 0.01) with increasing CC inclusion. Daily feed disappearance did not differ among CC inclusion levels for the overall 42-d study. Increasing dietary CC inclusion level linearly reduced nutrient digestibility of test diets (P < 0.01). In conclusion, CC is a safe feedstuff for broilers that can be fed at dietary inclusions up to and including 24% without adverse effects on broiler health.

Abstract
Mechanical loading has been widely considered to be a crucial regulatory factor for growth plate development, but the exact mechanisms of this regulation are still not completely understood. In the growth plate, parathyroid hormone-related protein (PTHrP) regulates chondrocyte differentiation and longitudinal growth. Cyclic mechanical strain has been demonstrated to influence growth plate chondrocyte differentiation and metabolism, whereas the relationship between cyclic mechanical strain and PTHrP expression is not clear. The objective of this study was to investigate whether short-term cyclic tensile strain regulates PTHrP expression in postnatal growth plate chondrocytes in vitro and to explore whether the organization of cytoskeletal F-actin microfilaments is involved in this process. To this end, we obtained growth plate chondrocytes from 2-week-old Sprague-Dawley rats and sorted prehypertrophic and hypertrophic chondrocytes using immunomagnetic beads coated with anti-CD200 antibody. The sorted chondrocytes were subjected to cyclic tensile strain of varying magnitude and duration at a frequency of 0.5 Hz. We found that cyclic strain regulates PTHrP expression in a magnitude- and time-dependent manner. Incubation of chondrocytes with cytochalasin D, an actin microfilament-disrupting reagent, blocked the induction of PTHrP expression in response to strain. The results suggest that short-term cyclic tensile strain induces PTHrP expression in postnatal growth plate prehypertrophic and hypertrophic chondrocytes and that PTHrP expression by these chondrocytes may subsequently affect growth plate development. The results also support the idea that the organization of cytoskeletal F-actin microfilaments plays an important role in mechanotransduction.

Abstract
In order to investigate the effect of manganese (Mn) deficiency on bone metabolism in chicks, ninety 1-day-old male Arbor Acre chicks were randomly divided into 3 groups and each group were given a diet having a different concentration of Mn (60 mg kg(-1), control group; 40 mg kg(-1), Mn-deficient group I; 8.7 mg kg(-1), Mn-deficient group II). The serum was collected at 42 days old. Tests were performed to evaluate the changes in the levels of PTH, CT, ALP, TrACP, HOP TNF-alpha, OC, Mn and Ca in the serum of the chicks and the results showed that the levels of CT, ALP, TrACP, HOP, and Mn decreased markedly (P < 0.05), while PTH, Ca, and TNF-alpha increased markedly (P < 0.05) due to manganese deficiency in the diet, which indicates that Mn deficiency results in disorder of bone regulatory hormones and enzymes of bone metabolism in the serum.

Abstract
Background Tibial dyschondroplasia (TD) is a common skeletal disorder in broiler chickens. It is characterized by the presence of a non-vascularized and unmineralized cartilage in the growth plate. Previous studies have investigated differential expression of genes related to cartilage development during latter stages of TD. The aim of our study was to identify differentially expressed genes (DEGs) in the growth plate of broiler chickens, which were associated with early stage TD. We induced TD using tetramethylthiuram disulfide (thiram) for 1, 2, and 6 days and determined DEGs with chicken Affymetrix GeneChip assays. The identified DEGs were verified by quantitative polymerase chain reaction (qPCR) assays. Results We identified 1630 DEGs, with 82, 1385, and 429 exhibiting at least 2.0-fold changes (P < 0.05) at days 1, 2, and 6, respectively. These DEGs participate in a variety of biological processes, including cytokine production, oxidation reduction, and cell surface receptor linked signal transduction on day 1; lipid biosynthesis, regulation of growth, cell cycle, positive and negative gene regulation, transcription and transcription regulation, and anti-apoptosis on day 2; and regulation of cell proliferation, transcription, dephosphorylation, catabolism, proteolysis, and immune responses on day 6. The identified DEGs were associated with the following pathways: neuroactive ligand-receptor interaction on day 1; synthesis and degradation of ketone bodies, terpenoid backbone biosynthesis, ether lipid metabolism, JAK-STAT, GnRH signaling pathway, ubiquitin mediated proteolysis, TGF-β signaling, focal adhesion, and Wnt signaling on day 2; and arachidonic acid metabolism, mitogen-activated protein kinase (MAPK) signaling, JAK-STAT, insulin signaling, and glycolysis on day 6. We validated seven DEGs by qPCR. Conclusions Our findings demonstrate previously unrecognized changes in gene transcription associated with early stage TD. The DEGs we identified by microarray analysis will be used in future studies to clarify the molecular pathogenic mechanisms of TD. From these findings, potential pathways involved in early stage TD warrant further investigation.

Abstract
Extracellular matrix mineralization is an essential physiologic process in bone, teeth, and hypertrophic cartilage. Matrix Gla protein (MGP), an inhibitor of mineralization, is expressed by chondrocytes and vascular smooth muscle cells to inhibit calcification of those soft tissues. Tibial dyschondroplasia (TD), a skeletal abnormality apparent as a plug of non-vascularized, non-mineralized, white opaque cartilage in the tibial growth plate of avian species can serve as a good model for studying process and genes involved in matrix mineralization and calcification. In this work, we studied the involvement of MGP in the development of TD, as well as in the processes of spontaneous and induced recovery from this syndrome. First, we found that during normal bone development, MGP is expressed in specific time and locations, starting from wide-spread expression in the yet un-ossified diaphysis during embryonic development, to specific expression in hypertrophic chondrocytes adjacent to the chondro-osseous junction and the secondary ossification center just prior to calcification. In addition, we show that MGP is not expressed in the impaired TD lesion, however when the lesion begins to heal, it strongly express MGP prior to its calcification. Moreover, we show that when calcification is inhibited, a gap is formed between the expression zones of MGP and BMP2 and that this gap is closed during the healing process. To conclude, we suggest that MGP, directly or through interaction with BMP2, plays a role as ossification regulator that acts prior to ossification, rather then simple inhibitor.

Abstract
The evaluation of the structure of the spongious substance of the tibiotarsal (TT) bones of the domestic duck aged 4 to 8 wk was performed using radiological analysis. The Trabecula program (Czerwiński, 1994) used in the study identified a map of radiological trabeculae and calculated the number, average volume, density, and width of trabeculae. It was stated that the number of trabeculae differed significantly (P ≤ 0.05) variant on age, sex, and a unique fragment of the studied bone. Six-week-old hens whose TT bones were most often exposed to deformities and fractures possessed attenuated bone mass. The number of trabeculae per 1 mm(2) during breeding was the lowest (10.34 and 9.54 mm(2) in the proximal and distal epiphyses, respectively). The tibial bones of the 6-wk-old hens also possessed the lowest volume of trabeculae (44.62 and 39.84% for the proximal and distal epiphyses, respectively). Dependant variances between the BW, the number of recognized radiological trabeculae, and the volume, density, and width of trabeculae were calculated using a selected correlation and regression coefficient (r = 0.41; P ≤ 0.05). Results expounded a unique linear relationship between BW and the volume of trabeculae. Indeed, the larger the BW, the more numerous the trabeculae observed. No significant correlation was determined between the BW and the number of recognized trabeculae nor their density and width. A small number of trabeculae and the lowered density may be the cause of fractures and deformities of the TT bones of the domestic duck.

Abstract
A disintegrin and metalloproteinase with thrombospondin motifs 9 (ADAMTS9) is known to influence aggrecan degradation in endochondral ossification, but its role has not been well understood. In the present study, in vitro gene expression of ADAMTS9 was investigated by RT-PCR in ATDC5 cells in which experimentally chondrogenic differentiation had been induced. We also investigated the protein localization and gene expression pattern of ADAMTS9 in the tibia growth plate cartilage of male mice in a day 1 neonate, 7-week-old young adult, and a 12-week-old adult by immunohistochemistry and in situ hybridization and compared the results with the expression of proliferating cell nuclear antigen (PCNA) and type X collagen for the identification of proliferative and hypertrophic chondrocyte phenotypes, respectively. We found the gene expression of ADAMTS9 by ATDC5 cells as a dual mode, both before the expression of type X collagen and after hypertrophic differentiation. The immunoreactivity of ADAMTS9 was observed in chondrocytes of proliferative and hypertrophic zones in the growth plate. The population of ADAMTS9 positive cells decreased with age. The results of the present study suggest that ADAMTS9 might have a role in aggrecan cleavage around the chondrocytes to allow chondrocyte proliferation and hypertrophy.

Abstract
Type X collagen (Col-X) deposition is a marker of terminal differentiation during chondrogenesis, in addition to appositional growth and apoptosis. The parathyroid hormone/parathyroid hormone related peptide (PTH/PTHrP) receptor, or PPR, is a G-Protein coupled receptor (GPCR), which activates several downstream pathways, moderating chondrocyte differentiation, including suppression of Col-X deposition. An Avian sterna model was used to analyze the PPR GPCR downstream kinase role in growth rate and extracellular matrix (ECM) including Col-II, IX, and X. Phosphatidylinositol kinase (PI3K), mitogen activating protein kinase (MAPK) and protein kinase A (PKA) were inhibited with specific established inhibitors LY294002, PD98059, and H89, respectively to test the hypothesis that they could reverse/inhibit the PTH/PTHrP pathway. Excised E14 chick sterna were PTH treated with or without an inhibitor and compared to controls. Sternal length was measured every 24 hr. Cultured sterna were immuno-stained using specific antibodies for Col-II, IX, or X and examined via confocal microscopy. Increased growth in PTH-treated sterna was MAPK, PI3K, and PKA dose dependent, suggesting growth was regulated through multiple pathways. Col-X deposition was rescued in PTH-treated sterna in the presence of PI3K or MAPK inhibitors, but not with the PKA inhibitor. All three inhibitors moderately disrupted Col-II and Col-IX deposition. These results suggest that PTH can activate multiple pathways during chondrocyte differentiation.

Abstract
Tibial dyschondroplasia (TD) is characterized by expansion of the proximal growth plates of the tibiotarsus that fail to form bone, lack blood vessels, and contain non-viable cells. Thiram (a carbamate pesticide), when fed to young broiler chicks, induces TD with high regularity and precision. We used this experimental model to understand the cause of the defects associated with TD by selecting and identifying the genes differentially expressed in the TD growth plate of broiler chickens. Broiler chicks at 7 days of age were randomly divided into two groups. After fasting overnight, they were fed with regular diet (control) or the same diet containing 100 mg/kg thiram for 96 h to induce TD (thiram-fed). mRNA was purified from the growth plates of control and thiram-fed broilers. Forward and reverse-subtracted cDNA libraries were generated by suppression subtractive hybridization technology. Ten selected genes from cDNA libraries were identified by real-time quantitative polymerase chain reaction. All were differentially expressed in TD growth plates (P<0.05 or P<0.01). The levels of collagen type X (Col X), pro-alpha-1 collagen type I (Col I alpha1), collagen type IX (Col IX), NADH dehydrogenase (NADH DH), cytochrome C oxidase subunit III (COX III), enolase 1, alpha (ENO1), carbonic anhydrase II (CA2) and heat shock protein 90 (Hsp90) mRNA transcripts were up-regulated, while the expression levels of Matrilin 3 (MATN3) and chondromodulin-I (ChM-I) were down-regulated. Col I and Hsp90 were detected by immunohistochemistry at different stages. Given that these genes are involved in matrix formation, endochondral ossification, developmental regulation, electron transport in the mitochondrial respiratory chain and vascularization, our findings may provide new insights into understanding the pathogenesis of TD.

Abstract
Tibial dyschondroplasia is a disease of rapid growth rate that occurs in many avian species. It is characterized by an avascular lesion in which the life span of the growth plate chondrocyte is essentially doubled. A characteristic pattern of gene expression and gene product localization has emerged that mimics the pattern observed with endoplasmic reticulum (ER) stress in growth plate chondrocytes. This activates a cell-survival mechanism called autophagy. The initial phases of this mechanism appear to originate in the avascular transition zone of the growth plate. Because specific genes and gene products are associated with autophagy and ER stress, it should now be possible to identify the mechanisms involved in the development of this cartilage abnormality. The potential biochemical pathways responsible for initiating ER stress are discussed.

Abstract
Two trials were conducted to determine if thiram-induced tibial dyschondroplasia (TD) in chickens was linked to a vitamin D deficiency and calcium homeostasis dysregulation, and whether feeding vitamin D fortified diets may prevent it. Day-old chickens were given grower diets containing different vitamin D products throughout the experiment until necropsy on day 16. Half of the birds in each feed group received thiram at levels of 100 ppm (trial 1) or 50 ppm (trial 2) between days 7-9 to induce TD. The birds were weighed, bled, and euthanized to determine TD incidences and severity by examining the growth plates. Tibial bones were used to measure biomechanical strength and ash content. Blood concentrations of 25-hydroxyvitamin D, Ca, P, alkaline phosphatase, and creatine kinase were measured in serum that showed no differences between different groups. Thiram reduced body weight and induced TD regardless of any vitamin D treatment to the same extent as untreated birds.

Abstract
Tibial dyschondroplasia (TD) is a prevalent skeletal abnormality associated with rapid growth rate in many avian species; it causes enormous economic losses and is an animal welfare problem. Tibial dyschondroplasia is characterized by the presence of a nonvascularized, nonmineralized lesion that extends from the epiphyseal growth plate into the metaphysis of the proximal tibiotarsal bones. The mechanisms underlying TD development are not known, although they have been extensively studied in broilers using different induction models. However, an effective model for TD induction in turkeys has never been described. The objective of this study was to establish such a model by using tetramethylthiuram disulfide (thiram), an agent that is frequently used in broilers to induce TD. We found that dramatically longer exposures to much higher concentrations of thiram were required to induce TD in turkeys vs. broilers. In contrast to broilers, in which 50 mg/kg of thiram induces a high incidence of severe TD within 10 d, in turkeys, an exposure to 400 mg/kg of thiram for 11 wk was necessary for the development of severe TD lesions. These results show different mechanisms for TD induction in these 2 closely related species, suggesting differences in TD etiology between them.

Abstract
The long bones of the developing skeleton arise from the process of endochondral ossification, which begins during the embryonic stages and resumes later in the growth plates located at the extremities of the long bones. This process includes commitment of cells to the chondrocytic lineage and further differentiation into hypertrophic chondrocytes, which subsequently undergo apoptosis and are replaced by osteoblasts laying down the trabecular bone. In this study we characterize, for the first time, the endochondral bone development of the turkey during embryonic and juvenile stages. Turkey tibias were collected on embryonic d 11, 14, and 18; and at 3 and 7 d posthatching, alcian blue and Von Kossa staining, alkaline phosphatase activity, and in situ expression of collagen types II and X were studied in these samples. We showed that the principles of bone development in the turkey follow the known vertebrate pattern, and that the initiation of ossification is related to the perichondrium and compact bone. These results increase the knowledge about this process in the turkey, which is an important animal in the agricultural industries.

Abstract
Matrix metalloproteinases (MMPs) play a crucial role in growth-plate vascularization and ossification by processes involving proteolytic cleavage and remodeling of the extracellular matrix (ECM). Their regulation in the growth plate is crucial for normal vs. impaired matrix assembly. Tibial dyschondroplasia (TD), a prevalent skeletal abnormality in avian species, is characterized by the formation of a nonvascularized, nonmineralized plaque in the growth plate. Here, we show differential regulation of MMPs in cultured chondrocytes from chickens and turkeys; retinoic acid (RA) elevated MMP-2 activity in both species, but only in chicken did it induce MMP-9 activity. In contrast, phorbol 12-myristate 13-acetate (PMA) treatment induced MMP-9 activity in turkey chondrocytes but not in those of chicken. Moreover, we found different developmental patterns of TD in chickens and turkeys in-vivo as lower concentrations of, and shorter exposure to thiram were required in chicken than in turkey for TD induction. Growth-plate cartilage taken from thiram-induced lesions had lower gelatinolytic and caseinolytic activities compared with normal cartilage. Likewise, thiram reduced MMP-2 and MMP-13 activity in both chicken and turkey chondrocytes in vitro, although 10-fold higher concentrations were required for this effect in the latter. Finally, the combined treatments of RA or PMA with thiram induced MMP-9 activity in turkey but not in chicken chondrocytes. Furthermore, RA combined with thiram synergistically upregulated its activity in turkey but not chicken chondrocytes. Taken together, these results suggest that mechanisms of MMP regulation differ in the growth plates of these closely related avian species, resulting in altered matrix assembly as exemplified by TD development.
