Screening for autophagy/hypoxia/ferroptosis/pyroptosis-related genes of tendon injury and repair in a rat model after celecoxib and lactoferrin treatment. J Orthop Surg Res 2023; 18:383. [PMID: 37231424 DOI: 10.1186/s13018-023-03856-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Accepted: 05/13/2023] [Indexed: 05/27/2023] Open
Abstract
BACKGROUND Tendon injuries are among the most common musculoskeletal disorders. Celecoxib possesses an effective anti-inflammatory activity in the tendon injury treatment. Lactoferrin has a great potential for the tendon regeneration. However, the efficacy of celecoxib combined with lactoferrin in the treatment of tendon injury has not been reported. In this study, we aimed to investigate the effect of celecoxib and lactoferrin on tendon injury and repair, and screen for the crucial genes associated with the tendon injury and repair. METHODS The rat tendon injury models were established and divided into four groups: normal control group (n = 10), tendon injury model group (n = 10), celecoxib treatment group (n = 10), and celecoxib + lactoferrin treatment group (n = 10). Then, RNA sequencing was performed to identify differentially expressed lncRNAs (DElncRNAs), miRNAs (DEmiRNAs) and mRNAs (DEmRNAs) in celecoxib treatment group and celecoxib + lactoferrin treatment group. Next, autophagy/hypoxia/ferroptosis/pyroptosis-related DEmRNAs were further identified. Subsequently, functional enrichment, protein-protein interaction (PPI) network and transcriptional regulatory network construction for these genes were performed. RESULTS The animal study demonstrated that combinational administration of celecoxib with lactoferrin rescued the harmful effects caused by celecoxib in the treatment of tendon injury. Compared to tendon injury model group, 945 DEmRNAs, 7 DEmiRNAs and 34 DElncRNAs were obtained in celecoxib treatment group, and 493 DEmRNAs, 8 DEmiRNAs and 21 DElncRNAs were obtained in celecoxib + lactoferrin treatment group, respectively. Subsequently, 376 celecoxib + lactoferrin treatment group-specific DEmRNAs were determined. Then, 25 DEmRNAs associated with autophagy/hypoxia/ferroptosis/pyroptosis were identified. CONCLUSIONS Several genes, such as, Ppp1r15a, Ddit4, Fos, Casp3, Tgfb3, Hspb1 and Hspa8, were identified to be associated with tendon injury and repair.

Abstract
Lactoferrin (Ltf), a naturally active glycoprotein, possesses anti-inflammatory, anti-microbial, anti-tumor, and immunomodulatory activities. Many published studies have indicated that Ltf modulates the proliferation of stem cells. However, the role of Ltf in the proliferation of satellite cells, an important cell type in muscle regeneration, has not yet been reported. Here, by using Ltf systemic knockout mice, we illustrate the role of Ltf in skeletal muscle. Results shows that Ltf deficiency impaired proliferation of satellite cells (SCs) and the regenerative capability of skeletal muscle. Mechanistic studies showed that ERK1/2 phosphorylation was significantly downregulated after Ltf deletion in SCs. Simultaneously, the cell cycle-related proteins cyclin D and CDK4 were significantly downregulated. Intervention with exogenous recombinant lactoferrin (R-Ltf) at a concentration of 1000 μg/mL promoted proliferation of SCs. In addition, intraperitoneal injection of Ltf effectively ameliorated the skeletal muscle of mice injured by 1.2% BaCl2 solution. Our results suggest a protective effect of Ltf in the repair of skeletal muscle damage. Ltf holds promise as a novel therapeutic agent for skeletal muscle injuries.

Abstract
We investigated the potential gastroprotective effects of chrysin on indomethacin induced gastric ulcers in rats. We used six groups of animals: control; indomethacin (Indo); reference (Ulcuran®); indomethacin + 25 mg/kg chrysin (Indo + CHR25); indomethacin + 50 mg/kg chrysin (Indo + CHR50); indomethacin + 100 mg/kg chrysin (Indo + CHR100). All doses of chrysin were given orally to rats before indomethacin. Gastric lesions were examined macroscopically and microscopically. The effects of treatment with chrysin were assessed versus a single dose of 30 mg/kg Ulcuran® (generic ranitidine) as reference standard. We also investigated gastric mucosal superoxide dismutase (SOD), glutathione (GSH), glutathione peroxidase (GPx), catalase (CAT), malonaldehyde (MDA) and arginase activities, and COX-2, PGE2, iNOS, TNF-α, IL-1β, NFκB, MPO, Bax, caspase-3 and 8-OHdG levels. We assessed caspase-3 and Bax levels using immunohistochemistry. Compared to the control and reference groups, SOD, CAT, GPx and arginase activities and GSH levels decreased, and MDA levels increased in the indomethacin induced gastric ulcer group. iNOS, TNF-α, IL-1β, NFκB, MAPK-14, MPO, Bax and 8-OHdG levels were increased in the indomethacin treated gastric group, while COX-2 activity and PGE2 levels were decreased. The three doses of chrysin co-administered with indomethacin increased COX-2 activity and PGE2 levels in rats with ulcers. Chrysin exhibited gastroprotective effects on indomethacin induced gastric ulcer due to its antioxidant, anti-inflammatory and anti-apoptotic activities.

Abstract
Lactoferrin (Lf) possesses various biological properties and therapeutic potentials being a perspective anti-inflammatory, antibacterial, antiviral, antioxidant, antitumor, and immunomodulatory agent. A significant body of literature has also demonstrated that Lf modulates regenerative processes in different anatomical structures, such as bone, cartilage, skin, mucosa, cornea, tendon, vasculature, and adipose tissue. Hence, this review collected and analyzed the data on the regenerative effects of Lf, as well as paid specific attention to their molecular basis. Furthermore, tissue and condition-specific activities of different Lf types as well as problems of their delivery to the targeted organs were discussed. The authors strongly hope that this review will stimulate researchers to focus on the highlighted topics thus accelerating the progress of Lf's wider clinical application.

Abstract
Objective: To evaluate the effects of administering diclofenac and ketoprofen, as well as the effects of environmental oxygen pressure variation on mandibular bone regeneration. Methods: Thirty-six guinea pigs were distributed into two equal groups. Mandibular bone defects were performed on both groups. Group A was monitored under oxygen pressure at altitude (3320msl, 107mm Hg). Group B was monitored at sea level oxygen pressure (150msl, 157mm Hg). Each group was subdivided into 3 equal groups (A1, A2, A3 and B1, B2, B3). Subgroups A1 and B1 were given diclofenac; subgroups A2 and B2 ketoprofen; subgroups A3 and B3 NaCl. Bone regeneration was evaluated histologically on days 15 and 30. Results: After 15 days in the group controlled at sea level, the level of osteoblasts presented by the control subgroup was significantly higher (28.00±2.65) compared to the diclofenac subgroup (16.00±6.25) and to the ketoprofen subgroup (18.00±4.36); (p=0.041). After 15 days in the group controlled at altitude, the level of osteoblasts was significantly higher in the control subgroup (38.00±5.29) compared to the diclofenac subgroup (21.67±6.35) and to the ketoprofen subgroup (19.33±2.52); p=0.007. After 30 days in the group at sea level there was no difference found in the cell counting; p>0.05. After 30 days in the group controlled at altitude, the level of osteoblast was significantly higher in the control subgroup (58.00±4.58) compared to the diclofenac subgroup (34.33±4.73) and the ketoprofen subgroup (34.00±11.14); (p=0.003). Conclusion: The administration of diclofenac and ketoprofen produced lower mandibular bone regeneration, the effect being significantly more negative at sea level.

Abstract
Objective Tendinopathy is a major clinical problem in sports medicine and is often difficult to treat. Traditional therapeutic approaches have focused on reducing inflammation, yet research suggests that little to no inflammation is present in the tendons that fail to heal. The purpose of this review was to evaluate the effectiveness of the available treatment options for tendinopathy and to inform best clinical practices. Design A narrative review. Methods A comprehensive search of electronic databases (PubMed, Google Scholar and Web of Science) was conducted to identify relevant studies through June 2016. Studies were deemed relevant if they were published in English and contained original research on the management of tendinopathy in humans. Results Studies varied in methodological quality and were often limited by small sample size and lack of sufficient control groups. Critical evaluation of the literature suggests that physical therapy with or without eccentric exercise should be considered a first-line treatment. Corticosteroids and nonsteroidal anti-inflammatory drugs provide short-term symptomatic relief, but long-term efficacy has not been demonstrated. Inconsistent results do not support the routine use of prolotherapy, platelet-rich plasma injections and topical nitric oxide patches. Operative intervention should be reserved until conservative measures fail or an obvious operative lesion is present. Conclusions While numerous therapeutic modalities exist for tendinopathy in the athlete, the ideal treatment protocol has not been clearly defined. The development of new targeted therapies for tendinopathy is likely to follow a greater understanding of the cellular and molecular mechanisms that underlie its pathogenesis.

Abstract
Introduction Recently, bone-active factors such as parathyroid hormone and lactoferrin, have been used in pre-clinical models to promote tendon healing. How-ever, there is limited understanding of how these boneactive factors may affect the cells of the ten-don themselves. Here, we present an in vitro study assessing the effects of parathyroid hor-mone and lactoferrin on primary tendon cells (tenocytes), and compare their responses to the tenogenic factors, PDGF, IGF-1 and TGF-β. Materials and Methods Tenocyte proliferation and collagen production were assessed by alamarBlue® and Sirius red as-says, respectively. To assess tenocyte trans-differentiation, changes in the expression of genes important in tenocyte, chondrocyte and osteoblast biology were determined using real-time PCR. Results Parathyroid hormone and lactoferrin had no effect on tenocyte growth or collagen production, with minimal changes in gene expression and no detrimental effects observed to suggest trans-differentiation away from tendon cell behaviour. Tenogenic factors PDGF, IGF-1 and TGF all increasetenocyte collagen production, however, the gene expression data suggests that PDGF promotes severe de-differentiation of the tenocytes. Discussion Our findings suggest that using parathyroid hormone or lactoferrin as a singular factor to promote tendon healing may not be of benefit, but for use in tendon-bone healing there would be no detrimental effect on the tendon itself.

Abstract
Lactoferrin (Lf), a multifunctional glycoprotein, is an important antimicrobial and immune regulatory protein present in neutrophils and most exocrine secretions of mammals. Lactoferricin (Lfcin) is located in the N-terminal region of this protein. In this review, the current state of research into Lf and Lfcin in China is described. Searching with HistCite software in Web Sci located 118 papers published by Chinese researchers from 2011–2015, making China one of the top 3 producers of Lf research and development in the world. The biological functions of Lf and Lfcin are discussed, including antibacterial, antiviral, antifungal, anticarcinogenic, and anti-inflammatory activities; targeted drug delivery, induction of neurocyte, osteoblast, and tenocyte growth, and possible mechanisms of action. The preparation and heterologous expression of Lf in animals, bacteria, and yeast are discussed in detail. Five Lf-related food additive factories and 9 Lf-related health food production companies are certified by the China Food and Drug Administration (CFDA). The latest progress in the generation of transgenic livestock in China, the safety of the use of transgenic animals, and future prospects for the uses of Lf and Lfcin are also covered.

Abstract
Exercising individuals commonly consume analgesics, but these medications alter tendon and skeletal muscle connective tissue properties, possibly limiting a person from realizing the full benefits of exercise training. I detail the novel hypothesis that analgesic medications alter connective tissue structure and mechanical properties by modifying fibroblast production of growth factors and matrix enzymes, which are responsible for extracellular matrix remodeling.

Abstract
Human palatine tonsil-derived mesenchymal stem cells (TMSCs) are known to be a new source of progenitor cells. Using waste tissue after tonsillectomy as a cell provider can be the biggest benefit of TMSCs, compared with other stem cells. The purpose of this study was to investigate tenogenic differentiation of TMSCs and to access the differential effects of transforming growth factor beta 3 (TGF-β3) on the tenogenesis of TMSCs. Human tonsil was obtained after tonsillectomy. Using a cytometric analysis, we were able to find that the TMSCs had typical mesenchymal stem cell markers: positive for CD73, CD90, and CD105, and negative for CD14, CD34, and CD45. Using TGF-β3, the expressions of tenocyte-specific genes and proteins, such as collagen type 1 (COL1), tenomodulin (TNMD), and scleraxis (SCX), were measured by a quantitative polymerase chain reaction (PCR), immunofluorescence staining, immunohistochemistry and Western blot analyses. Quantitative PCR assay showed that TGF-β3 significantly increased the expressions of tenocyte lineage marker genes, including COL1, TNMD, and SCX, at a 3-day treatment, compared with control. However, these increases were not found at long-term exposures (7 or 10 days), except that TNMD expression was maintained at 50 ng/mL at a 7-day exposure to TGF-β3. Like genes, the protein expression levels of COL1, TNMD, and SCX were also induced in TGF-β3-treated TMSCs in a 3-day treatment, which were maintained for 10 days, as evidenced by immunofluorescence staining, immunohistochemistry and Western blot analyses. This study demonstrated that TMSCs in tenogenic stimulation with TGF-β3 have a high tenogenic differentiation potential.
