Abstract
Observational studies have shown controversial associations between alcohol intake and radiographic osteoarthritis (OA). This study investigated whether this association was causal using a Mendelian randomization (MR) study in a population-based cohort in Korean. The study enrolled 2429 subjects (1058 men, 1371 women) from the Dong-gu Study. X-rays of the hand and knee joints were scored using a semi-quantitative grading system to calculate the total score of the hand and knee joints. ALDH2 rs671 genotyping was performed by high-resolution melting analysis. MR instrumental variable analysis and observational multivariable regression analysis were used to estimate the association between genetically predicted alcohol intake and the radiographic severity of OA. Subjects with the G/G genotype had a higher current alcohol intake than those with the G/A and A/A genotypes in both men and women (all P < 0.001). Men with the G/G genotype had higher total knee (P < 0.001) and hand scores (P = 0.042) compared to those with the G/A and A/A genotypes after adjusting for age and body mass index, but not in women. In the observational multivariable regression analysis, each alcohol drink per day in men was associated with increased knee (P = 0.001) and hand joint scores (P = 0.013) after adjustment, but not in women. In our MR analysis, utilizing ALDH2 rs671 genotypes as instrumental variables for alcohol consumption, has shown a significant link between each additional daily alcohol drink and increased radiographic joint severity in men.

Abstract
The obvious degeneration of articular cartilage occurs in the late stage of osteonecrosis of the femoral head (ONFH), which aggravates the condition of ONFH. This study aimed to demonstrate aberrant activation of autophagy processes in ONFH chondrocytes through bioinformatics and to predict and identify relevant hub genes and pathways. Differentially expressed genes (DEGs) were identified using R software in the GSE74089 dataset from the GEO database. DEGs were crossed with the Human Autophagy Database (HADb) autophagy genes to screen out autophagy-related differential genes (AT-DEGs). GSEA, GSVA, GO, and KEGG pathway enrichment analyses of AT-DEGs were performed. The STRING database was used to analyze the protein-protein interaction (PPI) of the AT-DEGs network, and the MCODE and CytoHubba plugin in the Cytoscape software was used to analyze the key gene cluster module and screen the hub genes. The PPI network of hub genes was constructed using the GeneMANIA database, and functional enrichment and gene connectivity categories were analyzed. The expression levels of hub genes of related genes in the ONFH patients were verified in the dataset GSE123568, and the protein expression was verified by immunohistochemistry in tissues. The analysis of DEGs revealed abnormal autophagy in ONFH cartilage. AT-DEGs in ONFH have special enrichment in macroautophagy, autophagosome membrane, and phosphatidylinositol-3-phosphate binding. In the GSE123568 dataset, it was also found that ATG2B, ATG4B, and UVRAG were all significantly upregulated in ONFH patients. By immunohistochemistry, it was verified that ATG2B, ATG4B, and UVRAG were significantly overexpressed. These three genes regulate the occurrence and extension of autophagosomes through the PI3KC3C pathway. Finally, we determined that chondrocytes in ONFH undergo positive regulation of autophagy through the corresponding pathways involved in three genes: ATG2B, ATG4B, and UVRAG.

Alcohol Clin Exp Res 2022; 46:915-927.

Abstract
BACKGROUND During bone fracture repair, mesenchymal stem cells (MSC) differentiate into chondrocytes and osteoblasts to form a fracture callus. Our laboratory previously reported that alcohol-exposed rodents with a surgically created tibia fracture display deficient fracture callus formation and diminished signs of endochondral ossification characterized by the absence of chondrocytes and mature hypertrophic chondrocytes, suggesting that alcohol may inhibit MSC differentiation. These findings led to our hypothesis that alcohol exposure inhibits mesenchymal stem cell chondrogenic differentiation within the developing fracture callus. METHODS In the present study, we utilized a lineage-tracing approach to determine which stage(s) of chondrogenic differentiation are affected by alcohol exposure. We utilized lineage-specific reporter mice to determine the effects of alcohol on MSC and early and late chondrogenic cell frequencies within the fracture callus. In addition, serially sectioned slides were stained immunofluorescently and immunohistochemically and quantified to determine the effect of alcohol on cell proliferation and apoptosis, respectively, within the fracture callus of alcohol-administered rodents. RESULTS Alcohol-administered rodents had a reduced fracture callus area at 4, 6, and 9 days postfracture. Alcohol had no effect on apoptosis in the fracture callus at any of the examined timepoints. Alcohol-administered rodents had significantly fewer proliferative cells in the fracture callus at 9 days postfracture, but no effect on cell proliferation was observed at earlier fracture callus timepoints. Alcohol-administered rodents had reduced Collagen2a1- and Collagen10a1-expressing cells in the developing fracture callus, suggesting that alcohol inhibits both early chondrogenic differentiation and later chondrocyte maturation during fracture callus development. CONCLUSION The data suggest that alcohol could affect normal fracture healing through the mitigation of MSC chondrogenic differentiation at the callus site.

Abstract
OBJECTIVE We sought to evaluate the effect of different concentrations of ethanol on phenotype and activity of articular chondrocyte synthesis of neonatal rats in 2-dimensional (2D) and 3-dimensional (3D) culture. METHODS Chondrocytes were cultured in chondrogenic medium with different concentrations of ethanol: 0.0% v/v (control); 0.05% v/v (8.6 mM); 0.25% v/v (42.9 mM), and 0.5% v/v (85.7 mM). Chondrocytes under 2D culture were subjected to MTT assay, while chondrocytes under 3D culture were processed for paraffin inclusion and stained by periodic acid Schiff (PAS) to evaluate mean chondrocyte diameter and percentages of cells, nucleus, cytoplasm, well-differentiated matrix, and PAS+ areas. The expression of gene transcripts for aggrecan, Sox9, and type II collagen was evaluated by real-time quantitative polymerase chain reaction. RESULTS There was no difference between groups by the MTT assay. PAS staining revealed that chondrocytes treated with 0.5% v/v ethanol had higher percentages of cytoplasm and nuclear areas, but with a reduction in PAS+ matrix area. The mean diameter of chondrocytes was similar between groups. The expression of aggrecan in the group treated with 0.5% v/v ethanol was lower in comparison to that in the control. In the groups treated with 0.25% v/v and 0.5% v/v ethanol, the percentage of differentiated cartilage was lower in comparison with that in the control. The group treated with 0.05% v/v ethanol was similar to the control in all parameters. CONCLUSIONS Ethanol acted directly on in vitro cultured articular chondrocytes of newborn rats, altering the chondrocyte phenotype and its synthesis activity, and these effects were dose dependent.

Abstract
Femoral head osteonecrosis, also known as avascular necrosis, is a disease with a multifactorial etiology, characterized by a profound change of bone architecture, which leads to the diminishing of bone resistance and femoral head collapse. The main causes that lead to femoral head necrosis are represented by the decrease of local blood perfusion and increase of intraosseous pressure, because of an excessive development of adipose tissue in the areolas of the trabecular bone tissue in the femoral head. The histopathological and immunohistochemical (IHC) study performed by us showed that most of bone trabeculae were damaged by necrotic-involutive processes, their sizes being reduced, both regarding their length and their diameter; generally, the spans were thin, fragmented, distanced among them, which led to the occurrence of some large areolar cavities, full of conjunctive tissue, rich in adipocytes. Some of the residual bone spans even presented microfractures. In the structure of the trabecular bone tissue, numerous cavities showed lack of content, which indicates the death of osteocytes inside, while the endosteum appeared very thin, with few osteoprogenitor, flattened, difficult to highlight cells. The IHC study showed a low reaction of the bone reparatory processes and a reduced multiplication capacity of bone cells involved in the remodeling and remake of the diseased bone tissue. Nevertheless, there were identified numerous young conjunctive cells (fibroblasts, myofibroblasts), positive to proliferating cell nuclear antigen (PCNA), cells that have a high capacity of multiplication, participating in the formation of a fibrous conjunctive tissue (sclerous) instead of the damaged bone trabeculae. The formation of fibrous conjunctive tissue causes the reduction of mechanical resistance of the femoral head and its collapse. The IHC study of the microvascularization in the femoral head damaged by aseptic osteonecrosis showed the presence of a very low vascular system, both in the residual bone trabeculae and in the sclerous conjunctive tissue. Of the inflammatory cells present in the spongy bone tissue of the femoral head affected by osteonecrosis, the most numerous ones were the macrophages. Both macrophages and T- and B-lymphocytes had a heterogenous distribution.

Abstract
ABSTRACT There is still debate regarding the pathogenic relationship between alcohol intake and osteoarthritis (OA). This study investigated the association between alcohol consumption and knee OA in a Korean population.Among 8058 subjects who participated in the Korea National Health and Nutrition Examination Survey (KNHANES) 2012, a total of 2917 subjects over the age of 50 and taken plain radiography was included in this analysis. Knee OA was classified based on the Kellgren-Lawrence (K-L) grading scale. Multivariate logistic regression analyses were used to evaluate the odds ratios (ORs) and 95% confidence intervals (CIs) of variables for knee OA (K-L grade ≥ 2).There were 1022 subjects with knee OA (29.2%). Subjects with knee OA tended to have lower daily alcohol intake (g/day) than did those without knee OA (10.4 [6.2-14.6] vs. 15.8 [12.8-18.8], P = .04). Similarly, those with knee OA demonstrated less makgeolli intake than did those without knee OA (P = .002). Subjects who consumed >0.6 g/day of beer also demonstrated less knee OA than did those who consumed <0.6 g/day of beer (OR 0.68, 95% CI 0.46-0.99). However, knee OA was not associated with the categories of alcohol consumption amount (g/day), including total daily alcohol intake (g/day), soju daily intake (g/day), and makgeolli daily intake (g/day) (P > .05 of all).Alcohol consumption was negatively associated with prevalence of knee OA in a Korean population. This preliminary observation will need to be confirmed in future studies.

Abstract
BACKGROUND During bone fracture repair, resident mesenchymal stem cells (MSCs) differentiate into chondrocytes, to form a cartilaginous fracture callus, and osteoblasts, to ossify the collagen matrix. Our laboratory previously reported that alcohol administration led to decreased cartilage formation within the fracture callus of rodents and this effect was mitigated by postfracture antioxidant treatment. Forkhead box protein O (FoxO) transcription factors are activated in response to intracellular reactive oxygen species (ROS), and alcohol has been shown to increase ROS. Activation of FoxOs has also been shown to inhibit canonical Wnt signaling, a necessary pathway for MSC differentiation. These findings have led to our hypothesis that alcohol exposure decreases osteochondrogenic differentiation of MSCs through the activation of FoxOs. METHODS Primary rat MSCs were treated with ethanol (EtOH) and assayed for FoxO expression, FoxO activation, and downstream target expression. Next, MSCs were differentiated toward osteogenic or chondrogenic lineages in the presence of 50 mM EtOH and alterations in osteochondral lineage marker expression were determined. Lastly, osteochondral differentiation experiments were repeated with FoxO1/3 knockdown or with FoxO1/3 inhibitor AS1842856 and osteochondral lineage marker expression was determined. RESULTS EtOH increased the expression of FoxO3a at mRNA and protein levels in primary cultured MSCs. This was accompanied by an increase in FoxO1 nuclear localization, FoxO1 activation, and downstream catalase expression. Moreover, EtOH exposure decreased expression of osteogenic and chondrogenic lineage markers. FoxO1/3 knockdown restored proosteogenic and prochondrogenic lineage marker expression in the presence of 50 mM EtOH. However, FoxO1/3 inhibitor only restored proosteogenic lineage marker expression. CONCLUSIONS These data show that EtOH has the ability to inhibit MSC differentiation, and this ability may rely, at least partially, on the activation of FoxO transcription factors.

Abstract
Like other ciliates, Philasterides dicentrarchi, the scuticociliate parasite of turbot, produces a feeding-only or growing stage called a trophont during its life cycle. Exposure of the trophonts to heat-inactivated serum extracted from the turbot host and containing specific antibodies that induce agglutination/immobilization leads to the production of a mucoid capsule from which the trophonts later emerge. We investigated how these capsules are generated, observing that the mechanism was associated with the process of exocytosis involved in the release of a matrix material from the extrusomes. The extruded material contains mucin-like glycoproteins that were deposited on the surface of the cell and whose expression increased with time of exposure to the heat-inactivated immune serum, at both protein expression and gene expression levels. Stimulation of the trophonts with the immune serum also caused an increase in discharge of the intracellular storage compartments of calcium necessary for the exocytosis processes in the extrusomes. The results obtained suggest that P. dicentrarchi uses the extrusion mechanism to generate a physical barrier protecting the ciliate from attack by soluble factors of the host immune system. Data on the proteins involved and the potential development of molecules that interfere with this exocytic process could contribute to improving the prevention and control of scuticociliatosis in turbot.

Abstract
Background Alcohol-induced osteonecrosis of the femoral head (ONFH) is caused by the interaction of genetic and environmental factors. Genetic variations of matrix metalloproteinase (MMP) system are associated with ONFH development and progression. In this study, we aimed to evaluate the relationships between MMP20 gene polymorphisms and the risk of alcohol-induced ONFH in Chinese Han males. Material/Methods In this case-control study, genotypes of 14 selected SNPs in the MMP20 gene were assayed using MassARRAY in 299 male cases with alcohol-induced ONFH and in 197 healthy males. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the influence of gene polymorphism on occurrence of alcohol-induced ONFH by allelic model analysis, genotype model analysis and haplotype analysis. Results After allelic model analysis, the minimum alleles of rs10895322, rs1784424, rs3781788, and rs1573954 correlated with an increased risk of alcohol-induced ONFH (P<0.05). Genetic model analysis revealed significant associations of 9 SNPs with alcohol-induced ONFH occurrence even after adjustment for age (P<0.05): 2 protective SNPs (rs1711423 and rs1784418) and 7 high-risk SNPs (rs10895322, rs1784424, rs3781788, rs7126560, rs1573954, rs1711399, and rs2292730). Moreover, 8 SNPs showed a statistically significant association with different clinical phenotypes (P<0.05). Beyond that, haplotype “CGGTTCCA” in MMP20 was discovered to correlate with a 1.63-fold increased risk of alcohol-induced ONFH (OR: 1.63, 95% CI: 1.15–2.30, P=0.0058). Conclusions Our data sheds new light on the associations of MMP20 gene polymorphisms with alcohol-induced ONFH predisposition in Chinese Han males.

Abstract
For patients undergoing total joint replacement (TJR), one of the complications, aseptic loosening, could cause serious consequences, such as revision surgery. In early research, pattern recognition receptors (PRRs) were reported to play vital roles in recognizing wear particles from the prosthesis and initiating an inflammation response. In this research, we aimed to clarify the role of nucleotide-binding and oligomerization domain containing protein 2 (NOD2), one of the PRRs, in macrophage-induced aseptic loosening in vivo and in vitro. High expressions of NOD2 and TNFα were observed from twenty patients who underwent primary or revision total hip replacements (THR). The effect of NOD2 on the activation of inflammation pathways was observed in RAW264.7 cells and CRISPR-Cas9 NOD2-knockout mice. The expressions of NOD2, the NF-κB pathway, the MAPK pathway and proinflammatory cytokine TNF-α in macrophages stimulated by wear particles were up-regulated. Otherwise, inhibition of NOD2 further up-regulated the expressions of NOD2, the NF-κB pathway, the MAPK pathway and TNF-α. Knockdown of the NOD2 gene enhanced the cranial osteolysis induced by titanium particles in a mouse model. In conclusion, our study demonstrated that NOD2 plays a negative role in osteolysis induced by titanium particles in vitro and in vivo.
