Excessive osteoclastogenesis-mediated osteoporosis has been recognized as a global health concern.Candidate compounds derived from medicinal plants or functional foods are promising to treat osteoporosis due to their high safety and efficiency.(−)-Epigallocatechin-3-gallate(EGCG)is the most abundant and biologically active polyphenol in green tea.It can inhibit osteoclastogenesis in vitro by blocking receptor activator of nuclear factor(NF)-κB(RANK)signaling pathways.This study used the ovariectomized(OVX)mouse model to estimate the therapeutic effect of EGCG on osteoporosis and verified the molecular mechanism in vivo.The results revealed that EGCG significantly inhibited the OVX-induced body weight gain.Moreover,no adverse effects were observed on blood glucose,histomorphological features,weights,as well as indices of liver and kidney in OVX mice.EGCG could significantly ameliorate bone loss in OVX mice by inhibiting osteoclastogenesis.This effect was evidenced by the reduced number of osteoclasts and the increased trabecular bone area in the femurs.Moreover,EGCG inhibited the activities of c-telopeptide of type I collagen(CTX-I)and tartrate-resistant acid phosphatase 5b(TRACP-5b)and strengthened bone gla protein(BGP)and procollagen I N-terminal peptide(PINP)activities in OVX mice.Mechanistically,EGCG significantly downregulated the expression of osteoclastogenesis-related marker genes and proteins,including nuclear factor of activated T cells,cytoplasmic 1(NFATc1),c-Fos,tartrate-resistant acid phosphatase(TRAP),c-Src,and cathepsin K.In addition,the phosphorylation levels of p65,c-Jun N-terminal kinase(JNK),extracellular signal-regulated kinase 1/2(ERK1/2),p38,and protein kinase B(AKT)were significantly suppressed in OVX mice.It was found that EGCG could alleviate OVX-induced bone loss in mice by suppressing osteoclastogenesis by blocking the NF-κB,mitogen-activated protein kinase(MAPK),and AKT signaling pathways.EGCG has the potential to prevent and treat osteoclast-related diseases such as osteoporosis. 展开更多

BACKGROUND Inguinal hernias are common after surgery.Tension-free repair is widely accepted as the main method for managing inguinal hernias.Adequate exposure,coverage,and repair of the myopectineal orifice(MPO)are necessary.However,due to differences in race and sex,people’s body shapes vary.According to European guidelines,the patch should measure 10 cm×15 cm.If any part of the MPO is dissected,injury to the nerves,vascular network,or organs may occur during surgery,thereby leading to inguinal discomfort,pain,and seroma formation after surgery.Therefore,accurate localization and measurement of the boundary of the MPO are crucial for selecting the optimal patch for inguinal hernia repair.AIM To compare the size of the MPO measured on three-dimensional multislice spiral computed tomography(CT)with that measured via laparoscopy and explore the relevant factors influencing the size of the MPO.METHODS Clinical data from 74 patients who underwent laparoscopic tension-free inguinal hernia repair at the General Surgery Department of the First Affiliated Hospital of Anhui University of Science and Technology between September 2022 and July 2024 were collected and analyzed retrospectively.Transabdominal preperitoneal was performed.Sixty-four males and 10 females,with an average age of 58.30±12.32 years,were included.The clinical data of the patients were collected.The boundary of the MPO was measured on three-dimensional CT images before surgery and then again during transabdominal preperitoneal.All the preoperative and intraoperative data were analyzed via paired t-tests.A t-test was used for comparisons of age,body mass index,and sex between the groups.In the comparative analysis,a P value less than 0.05 indicated a significant difference.RESULTS The boundaries of the MPO on 3-dimensional CT images measured 7.05±0.47 cm and 6.27±0.61 cm,and the area of the MPO was 19.54±3.33 cm^(2).The boundaries of the MPO during surgery were 7.18±0.51 cm and 6.17±0.40 cm.The errors were not statistically significant.However,the intraoperative BD(the width of the MPO,P=0.024,P<0.05)and preoperative AC(the length of the MPO,P=0.045,P<0.05)significantly differed according to sex.The AC and BD measurements before and during surgery were not significantly different according to age,body mass index,hernia side or hernia type(P>0.05).CONCLUSION The application of this technology can aid in determining the most appropriate dissection range and patch size. 展开更多

Steroidal alkaloids are the main active components in many medicinal plants and exhibit diverse biological activities.Axillaridine A(AA)is a newly discovered steroidal alkaloid.However,whether AA could suppress osteoclastogenesis and alleviate ovariectomy-induced bone loss in mice remains unknown.In vitro,AA significantly suppressed the receptor activator of nuclear factor-κB(NF-κB)ligand(RANKL)-induced osteoclast differentiation via downregulating the expression of osteoclastogenesis-related marker genes,proteins,and transcriptional regulators,including tartrate-resistant acid phosphatase(TRAP),c-Src,matrix metallopeptidase-9(MMP-9),cathepsin K,nuclear factor of activated T cells,cytoplasmic 1(NFATc1),and c-Fos.This was achieved by blocking RANKL-RANK interaction and inhibiting RANKL-mediated RANK signaling pathways,including NF-κB,AKT,and mitogen-activated protein kinases(MAPKs)in osteoclast precursors.In vivo,AA significantly inhibited the ovariectomized(OVX)-induced body weight gain and blood glucose increase in mice.AA did not adversely affect the histomorphologies,weights,and indices of the kidney and liver in OVX mice.AA effectively ameliorated bone loss in OVX mice by inhibiting osteoclastogenesis.AA significantly inhibited the serum levels of tartrate-resistant acid phosphatase 5b(TRACP-5b)and C-telopeptide of type I collagen(CTX-I).AA significantly inhibited the OVX-induced expression of osteoclastogenesis-related marker genes and proteins in the femur.In summary,AA alleviates ovariectomy-induced bone loss in mice by suppressing osteoclastogenesis via inhibition of RANKL-mediated RANK signaling pathways and could be potentially used for the prevention and treatment of osteoclastrelated diseases such as osteoporosis. 展开更多

People living long-term in areas with UV will cause premature photoaging.An abnormal reduction in autophagy is a key feature of photoaging,and p38 MAPK has been regarded as a key regulator of autophagy.Isothiocyanate is one of the main active components of Moringa oleifera Lam.seeds.Studies have reported that M.oleifera Lam.seeds iso thiocyanate(MITC)has anticancer,anti-inflammatory,cardio metabolic repair,nervous system protection,blood lipid regulation and diabetes prevention properties.However,the molecular mechanisms of MITC with protective effects against skin photoaging have not been studied thus far.In this study,we aimed to evaluate the antiphotoaging activity of MITC and to investigate the effect of p38 MAPK-dependent autophagy in vivo and in vitro models of photoaging.In this research we found that MITC can reverse the intracellular reactive oxygen species(ROS)content and inhibit the activation of p38 MAPK to improve the autophagy level,reduce the expression of matrix metalloproteinases(MMPs),and finally protect against photoaging by UV.Our results will uncover the molecular mechanisms of MITC that play a role in the protective effects against skin photoaging,provide helpful information for developing MITC as an anti-photoaging plant material and improve the utilization of M.oleifera Lam.seeds. 展开更多

Moringa oleifera have laxative effects,but their active compositions and mechanisms are not very clear thus far.To this end,we systematically explored the active components and mechanism of M.oleifera leaves in relieving constipation by using the slow transit constipation(STC)mouse model and network pharmacology.The results of animal experiments showed that M.oleifera aqueous extract(MOA)had good laxative activity,and its 70%alcohol soluble part(ASP)also showed significant laxative activity(P<0.01).Network pharmacological prediction results suggested that L-phenylalanine(Phe)was the key compound of ASP,and it might relieve constipation through tachykinin receptor 1(TACR1)and three kinds of adrenergic receptors,includingα_(1A)(ADRA1A),α_(2A)(ADRA2A),andα_(2B)(ADRA2B).Further animal experiment results showed that Phe significantly promoted gastrointestinal motility.Phe may relieve STC by enhancing the release of substance P(SP)and upregulating the m RNA expression of TACR1 in the ileum.Importantly,Phe may also promote intestinal movement by downregulating the m RNA expression of ADRA2A and ADRA2B and upregulating the m RNA expression of Calm and the m RNA and protein expression of myosin light chain 9 in the ileum,thereby activating the G protein-coupled receptor-myosin light chain signaling pathway.These results lay a foundation for the application of M.oleifera and Phe in constipation. 展开更多

Obesity has brought great challenges to global human health,and how to effectively prevent and control the occurrence and development of obesity has become an urgent problem.The role and mechanism of 4-[(α-Lrhamnosyloxy)benzyl]isothiocyanate(MITC),an active ingredient of Moringa oleifera Lam.,in the regulation of lipid metabolism have not been comprehensively investigated.In the present study,we investigated the mechanism of MITC in inhibiting lipid accumulation in mice fed with a high-fat diet(HFD)in terms of both lipolysis and central appetite regulation mediated by the gut microbe-gut-brain axis.MITC enhanced the characteristic indices associated with HFD mice and also promoted adipocytolysis and brown fat thermogenesis.Moreover,MITC was observed to improve leptin resistance,modulate the composition of gut microbiota such as Ruminococcaceae,Parasutterella,and Acetatifactor,promote 5-hydroxytryptamine secretion,further enhance the secretion of glucagon-like peptide-1(GLP-1)and peptide tyrosine-tyrosine(PYY)to activate peroxisome proliferator-activated receptor(PPAR)signaling in the hypothalamus,and modulate feeding behavior to inhibit lipid accumulation in HFD mice.These data suggest that MITC supplementation can help to alleviate obesity or obesity-related diseases. 展开更多

Tumor necrosis factor-α(TNF-α)is a key player in the pathogenesis of rheumatoid arthritis(RA)and considered a promising target for therapeutic drug development.Activation of the nuclear factor-kappa B(NF-κB)pathway upon TNF-αbinding to its receptor is crucial for progression of RA.Stephanine(SA),an isoquinoline aporphine-type alkaloid recently identified in Stephania plants,exhibits anti-inflammatory properties,but its underlying mechanisms of action are unknown at present.In this study,we explored whether SA could ameliorate RA through inhibition of the NF-κB signaling pathway in association with TNF-αactivity.Our experiments revealed a binding affinity(K_(D))of SA for TNF-αof 2.934×10^(-6)mol/L.Additionally,SA at a concentration of 10μmol/L effectively hindered the binding of TNF-αto its receptors tumor necrosis factor receptor 1(TNFR1)and TNFR2.In vitro,SA prevented TNF-α-induced death of L929 cells and blocked NF-κB activation triggered by TNF-αin 293-TNF-αresponsive,as well as human fibroblast-like synoviocytes(HFLS)and human RA fibroblast-like synoviocytes(MH7A)cell lines.Furthermore,in a collagen-induced arthritis(CIA)mouse model,SA alleviated the symptoms of RA through suppression of NF-κB signaling.Our collective findings support the therapeutic efficacy of SA,a natural compound targeting TNF-α,in the management of RA. 展开更多

Insects first began evolving hundreds of millions of years ago,and aided by gut microbes,they have been consuming hydrocarbon polymers ever since.Few man-made plastic polymers are chemically novel,so it is reasonable that insect/microbe systems can be found or developed to degrade them rapidly.However,remediation of global plastic waste problems should involve more than just conversion into CO_(2).Some industryscale microbial enzymatic degradation of plastic polymers may yield valuable monomers,but the plastic waste starting material must be of uniform chemistry and clean.This adds cost to the process.Many insect species can be utilized for animal feed as well as human food.Some of these insects have the capability to degrade plastic polymers.However,valorizing plastic wastes by producing edible insects or useful frass has largely been overlooked.Here we assemble the current knowledge of plastic degradation rates by insects.In addition,we also show the first instance of insect degradation of polyurethane and the first identification and isolation of insect gut fungi as directly aiding insect degradation. 展开更多

Walnut dreg protein hydrolysates(WDPHs)exhibit a variety of biological activities,however,the cyclooxygenase-2(COX-2)inhibitory peptide of WDPHs remain unclear.The aim of this study was to rapidly screen for such peptides in WDPHs through a combination of in silico and in vitro analysis.In total,1262 peptide sequences were observed by nano liquid chromatography/tandem mass spectrometry(nano LC-MS/MS)and 4 novel COX-2 inhibitory peptides(AGFP,FPGA,LFPD,and VGFP)were identified.Enzyme kinetic data indicated that AGFP,FPGA,and LFPD displayed mixed-type COX-2 inhibition,whereas VGFP was a non-competitive inhibitor.This is mainly because the peptides form hydrogen bonds and hydrophobic interactions with residues in the COX-2 active site.These results demonstrate that computer analysis combined with in vitro evaluation allows for rapid screening of COX-2 inhibitory peptides in walnut protein dregs. 展开更多

Since its outbreak in 1993, the virus has caused huge economic losses. Studies have confirmed that in the early stage of infection, VP28, the main envelope protein of WSSV, as a viral adhesion protein, binds to PcRab7 of <em>Penaeus chinensis</em> to help the virus enter the host cells. Understanding the mechanism of PcRab7-VP28 interaction is of great significance to understand the mechanism of WSSV infection and the development of antiviral drugs. In this research, the interaction interface and interaction sites were predicted by using the methods of molecular simulations. Results showed that VP28 binds to the second <em>β</em>-sheet (L73-D86) of PcRab7, which is consistent with the region detected in previous studies. Furthermore, we speculated the possible interaction sites in PcRab7 are E81, F77 and D76. These results may contribute to a deep understanding of the infection mechanism of WSSV on the host. 展开更多

Most proteins adopt an approximate structural symmetry. However, they have no symmetry detectable in their sequences and it is unclear for most of these proteins whether their structural symmetry originates from duplication. As one of the six popular folds (super-folds) possessing an approximate structural symmetry, the triosephosphate isomerase barrel (TIM-barrel) domain has been widely studied. Using modified recurrent quantification analysis of primary sequences, we identified the same 2-, 3-, and 4-fold symmetry pattern as their tertiary structures. This result indicates that the symmetry in tertiary structure is coded by symmetry in the primary sequence and that the TIM-barrel adopts a 2-, 3-, or 4-fold repeat pattern during evolution. This discovery will be useful for understanding the evolutionary mechanisms of this protein family and the symmetry pattern that may be a clue into the ancient origin of duplication of half-barrels or the β a unit. 展开更多

White spot syndrome virus (WSSV) is one of the most important pathogens that endanger the global shrimp aquaculture. Studies have confirmed that in the early stage of infection, VP28, the main envelope protein of WSSV, is used as a viral adhesion protein to bind PcRab7 of Penaeus chinensis, helping virus enter the host cells, resulting in shrimp infection. Hence, inhibition of envelope protein VP28 would be a novel way to deal with the infection. Peptide 2E6 was confirmed to have a high specificity and blocked virus infection. However, the mechanism by which it combines with VP28 is not clear. Clarifying the binding mechanism between peptides and VP28 is of great significance for further optimization and screening of antiviral peptides. In this research, the MD simulation and binding free energy analysis were implemented to validate and capture intermolecular interactions aims to clarify the blocking mechanism. 展开更多

Titanium(Ti)and its alloy implants often face issues such as insufficient tissue adhesion and vulnerability of the bio inert surface.Given that the long-term stability of implants depends on their perfect integration with the surrounding tissues to withstand various environmental stresses,current research mainly focuses on mimicking the structure of the extracellular matrix.The aim is to promote bone tissue formation through regulation of the immune response by metal ions,thereby enhancing the effectiveness of tissue integration.The self-assembled zinc(Zn)-doped hydroxyapatite nanoparticles(nHA)with polydopamine(PDA)and copper ions(Cu^(2+))was deposited onto the alkali treated Ti surface to fabricate the P-Zn-Cu/Ti coating.The so-constructed multifunc-tional coating with bionic micro/nano-structures on the Ti surface can achieve the sequential release of Cu^(2+)and zinc ions(Zn^(2+))through the rapid release of Cu^(2+)in the early stage and the slow release of Zn^(2+),and followed the functional characteristics of sequentially regulating antibacterial,immune,and osteogenic responses.This study presents a promising strategy to address the challenges associated with the failure of Ti implants,thus promoting the development of implant technology and improving clinical efficacy. 展开更多

Tea is the world's oldest and most popular caffeine-containing beverage with immense economic, medicinal, and cultural importance. Here, we present the first high-quality nucleotide sequence of the repeat-rich (80.9%), 3.02-Gb genome of the cultivated tea tree Camellia sinensis. We show that an extraordinarily large genome size of tea tree is resulted from the slow, steady, and long-term amplification of a few LTR retrotransposon families. In addition to a recent whole-genome duplication event, lineage-specific expansions of genes associated with flavonoid metabolic biosynthesis were discovered, which enhance catechin production, terpene enzyme activation, and stress tolerance, important features for tea flavor and adaptation. We demonstrate an independent and rapid evolution of the tea caffeine synthesis pathway relative to cacao and coffee. A comparative study among 25 Camellia species revealed that higher expression levels of most flavonoid- and caffeinebut not theanine-related genes contribute to the increased production of catechins and caffeine and thus enhance tea-processing suitability and tea quality. These novel findings pave the way for further metabolomic and functional genomic refinement of characteristic biosynthesis pathways and will help develop a more diversified set of tea flavors that would eventually satisfy and attract more tea drinkers worldwide. 展开更多

Dendrobium officinale Kimura et Migo is a traditional Chinese orchid herb that has both ornamental value and a broad range of therapeutic effects. Here, we report the first de novo assembled 1.35 Gb genome se- quences for D. officinale by combining the second-generation Illumina Hiseq 2000 and third-generation PacBio sequencing technologies. We found that orchids have a complete inflorescence gene set and have some specific inflorescence genes. We observed gene expansion in gene families related to fungus symbiosis and drought resistance. We analyzed biosynthesis pathways of medicinal components of D. officinale and found extensive duplication of SPS and SuSy genes, which are related to polysaccharide generation, and that the pathway of D. officinale alkaloid synthesis could be extended to generate 16- epivellosimine. The D. officinale genome assembly demonstrates a new approach to deciphering large complex genomes and, as an important orchid species and a traditional Chinese medicine, the D. officinale genome will facilitate future research on the evolution of orchid plants, as well as the study of medicinal components and potential genetic breeding of the dendrobe. 展开更多
