Summary: Abnormal subchondral bone remodeling leading to sclerosis is a main feature of osteoarthritis. Osteomodulin (OMD), a proteoglycan, is associated with the sclerotic phenotype. This study found that OMD binds to RANKL and inhibits osteoclastogenesis, thus regulating bone remodeling and contributing to bone and cartilage homeostasis. Targeting OMD may be a promising personalized approach for osteoarthritis.

Summary: This paper reports the chemical synthesis of polylactosamine fragments up to 22-mer using a blockwise synthetic approach. The synthesis of an octasaccharide of keratan sulfate glycan was achieved using large building blocks as glycosyl donors and acceptors. The coupling reaction between these building blocks facilitated the purification of glycosylated products.

Summary: This study aims to characterize bone mineralization using an in-vivo long bone fracture healing model in the rat. Multi-scale measurements indicated that zinc is required for both the initial mineral deposition and resorption processes, zinc and MMP-13 show similar spatio-temporal trends during early mineralization, and iron acts locally and in coordination with zinc during mineralization. These findings improve the understanding of bone mineralization.

Summary: Achilles tendon rupture is a common medical condition that can result in functional loss. The healing process is slow and can be affected by heterotopic ossification (HO), which is the pathological formation of bone tissue instead of tendon tissue. This study used advanced imaging techniques to examine the temporal and spatial progression of HO during Achilles tendon healing in a rat model. The results revealed that HO deposition begins as early as one week after injury in the distal stump and mostly grows on preexisting HO deposits. These deposits become larger and calcified, occupying up to 10% of the tendon volume. The study provides valuable insights into the ossification process in healing tendons.

Summary: The gene encoding the key GlcNAc sulfation enzyme CHST2 is induced by Snail in multiple breast cancer cells. Depletion of CHST2 inhibits breast cancer cell migration and metastasis, while overexpression of CHST2 promotes cell migration and lung metastasis in nude mice. Blocking the cell surface MECA79 antigen and sulfation inhibitor sodium chlorate effectively inhibit the cell migration induced by CHST2. These findings provide new insights into the biology of Snail/CHST2/MECA79 axis in breast cancer progression and metastasis, and potential therapeutic strategy for breast cancer metastasis.

Summary: In arthroscopic procedures in horses, the synovial membrane in osteoarthritis (OA) presents distinctive characteristics compared to osteochondritis dissecans (OCD). The OA group showed higher macroscopic scores and correlation between macroscopic and histological aspects of the membrane, with decreased IL-10 expression and higher IL-1 beta and IL-6 concentrations. OCD group exhibited similarities in macroscopic and histological aspects in comparison to the control and OA groups.

Summary: The negative charge of glycosaminoglycans (GAG) allows them to form complexes with positively charged biomolecules and ions, regulating homeostatic functions. Copying these interactions enables the assembly of biofunctional devices with unprecedented biocompliance. However, there are challenges in complexing GAG into intricate three-dimensional networks.

Summary: This study found that pancreatic tumor tissues exhibit increased sulfation levels, particularly Delta Di-4S and Delta Di-6S, while the changes in KS were not significant. The expression levels of CHST1 and CHST4 were significantly increased and could be used to differentiate between healthy and cancerous tissues. The up-regulation of CHST3, CHST12, CHST13, and CHST15 was directly correlated with sulfation.

Summary: Research findings suggest that certain protein concentrations are significantly related to poor surgical outcomes, while others are not. Bilateral masticatory muscle palpation pain is associated with disc displacement and osteoarthritis diagnoses, which may lead to unfavorable surgical outcomes. The multivariate model indicates that chronic inflammatory arthritis and patient-reported TMJ disability might be related to an unfavorable outcome.

Summary: This study aimed to investigate the relationship between cytokine concentrations in synovial fluid and synovial tissue and analyze the correlation between clinical parameters reflecting local inflammation and cytokine concentrations. The results showed weak correlations between cytokine concentrations in synovial fluid and synovial tissue, except for IL-8. Synovial tissue seemed to better reflect inflammation, suggesting the need for further exploration of synovial tissue in TMJ pathology and inflammation research.

Summary: Oral cGVHD is a heterogeneous clinical disorder, and its diagnosis and assessment still rely on clinical interpretation and patient-reported symptoms. This study highlights the importance of immunohistopathological profiles, specifically CD4, CD8, and CD68 immune profiling, and histological grading for staging oral cGVHD, to broaden our understanding of the biology and individual disease course.

Summary: Chronic Graft-versus-Host Disease (cGVHD) is a common complication after allogenic hematopoietic cell transplantation (HCT). It frequently affects the mouth and can be diagnosed by mucosal lichenoid lesions, salivary gland dysfunction, and limited oral aperture. The pathophysiology of oral cGVHD involves acute and chronic inflammation, dysregulated immunity, and fibrotic healing, which may lead to increased malignant transformation rate.

Summary: This study developed new techniques to define zones of BMU activity based on the 3D morphology of remodeling spaces in rabbit cortical bone and integrated morphological data with the BMU longitudinal erosion rate (LER) to elucidate the spatial-temporal coordination of BMUs and estimate mineral apposition rate (MAR). The results showed that the manual and semi-automated methods accurately defined the zones of remodeling spaces, and these techniques have the potential to assess dynamic parameters of bone resorption and formation.

Summary: Age- and disuse-related bone loss both lead to decreases in bone mineral density, cortical thickness, and trabecular thickness and connectivity. It is important to experimentally compare these two mechanisms at a structural and transcriptomic level to better understand their similarities and differences. This study compares the effects of hindlimb unloading and aging on bone microarchitecture and gene expression in mice, finding that while both induce similar changes, aging has a greater impact on the transcriptome and tissue level.

Summary: Osteogenesis imperfecta is a hereditary bone disease that weakens bones and increase fracture risk. Current interventions mainly focus on increasing bone mass, but the compromised tissue-level material properties are not addressed. A study found that a RAL analog could reduce fracture risk, but further development is needed for optimal results in patients with osteogenesis imperfecta.

Summary: The study analyzed the relationship between serum lumican levels and osteosarcopenia in older adults, showing that older adults with osteosarcopenia had lower serum lumican levels. Lower serum lumican levels were associated with reduced bone mass and grip strength, indicating that lumican levels could be used as a biomarker for assessing the risk of osteosarcopenia, osteoporosis, or sarcopenia in older adults.

Summary: Intramembranous bone regeneration is important in joint and tooth replacement, but its underlying mechanisms are not well understood. This study found that increased periostin gene expression preceded increases in osteogenic genes during bone regeneration. Using a genetic mouse model, the researchers discovered that cells transiently expressing periostin played a critical role in intramedullary intramembranous bone regeneration.

Summary: The increased risk of fractures observed in adults with type 1 diabetes (T1D) cannot be solely explained by modest decreases in areal bone mineral density (BMD). Accumulation of advanced glycation endproducts (AGEs) in bone has been suggested as a possible cause for the increased bone fragility in diabetes. Although the evidence linking AGEs and fractures in individuals with T1D is limited, recent data show that AGEs, as measured by skin intrinsic fluorescence, are a risk factor for lower BMD in T1D. Further research is needed to determine if there is a causal relationship between fractures and AGEs in T1D. If confirmed, this could lead to interventions that can reduce AGE accumulation and ultimately reduce fractures in T1D patients.
