Zhu Z, Deng X, Xie W, Li H, Li Y, Deng Z. Pharmacological effects of bioactive agents in earthworm extract: A comprehensive review. Animal Model Exp Med 2024. [PMID: 38957072 DOI: 10.1002/ame2.12465] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Accepted: 06/17/2024] [Indexed: 07/04/2024] Open
Abstract
This review compiles information from the literature on the chemical composition, pharmacological effects, and molecular mechanisms of earthworm extract (EE) and suggests possibilities for clinical translation of EE. We also consider future trends and concerns in this domain. We summarize the bioactive components of EE, including G-90, lysenin, lumbrokinase, antimicrobial peptides, earthworm serine protease (ESP), and polyphenols, and detail the antitumor, antithrombotic, antiviral, antibacterial, anti-inflammatory, analgesic, antioxidant, wound-healing, antifibrotic, and hypoglycemic activities and mechanisms of action of EE based on existing in vitro and in vivo studies. We further propose the potential of EE for clinical translation in anticancer and lipid-modifying therapies, and its promise as source of a novel agent for wound healing and resistance to antibiotic tolerance. The earthworm enzyme lumbrokinase embodies highly effective anticoagulant and thrombolytic properties and has the advantage of not causing bleeding phenomena due to hyperfibrinolysis. Its antifibrotic properties can reduce the excessive accumulation of extracellular matrix. The glycolipoprotein extract G-90 can effectively scavenge reactive oxygen groups and protect cellular tissues from oxidative damage. Earthworms have evolved a well-developed defense mechanism to fight against microbial infections, and the bioactive agents in EE have shown good antibacterial, fungal, and viral properties in in vitro and in vivo experiments and can alleviate inflammatory responses caused by infections, effectively reducing pain. Recent studies have also highlighted the role of EE in lowering blood glucose. EE shows high medicinal value and is expected to be a source of many bioactive compounds.

Lumbrokinase Extracted from Earthworms Synergizes with Bevacizumab and Chemotherapeutics in Treating Non-Small Cell Lung Cancer by Targeted Inactivation of BPTF/VEGF and NF-κB/COX-2 Signaling. Biomolecules 2024; 14:741. [PMID: 39062456 PMCID: PMC11274885 DOI: 10.3390/biom14070741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 06/11/2024] [Accepted: 06/18/2024] [Indexed: 07/28/2024] Open
Abstract
As a kind of proteolytic enzyme extracted from earthworms, lumbrokinase has been used as an antithrombotic drug clinically. Nevertheless, its potential in anti-cancer, especially in anti-non-small cell lung cancer (NSCLC), as a single form of treatment or in combination with other therapies, is still poorly understood. In this study, we explored the anti-tumor role and the responsive molecular mechanisms of lumbrokinase in suppressing tumor angiogenesis and chemoresistance development in NSCLC and its clinical potential in combination with bevacizumab and chemotherapeutics. Lumbrokinase was found to inhibit cell proliferation in a concentration-dependent manner and caused metastasis suppression and apoptosis induction to varying degrees in NSCLC cells. Lumbrokinase enhanced the anti-angiogenesis efficiency of bevacizumab by down-regulating BPTF expression, decreasing its anchoring at the VEGF promoter region and subsequent VEGF expression and secretion. Furthermore, lumbrokinase treatment reduced IC50 values of chemotherapeutics and improved their cytotoxicity in parental and chemo-resistant NSCLC cells via inactivating the NF-κB pathway, inhibiting the expression of COX-2 and subsequent secretion of PGE2. LPS-induced NF-κB activation reversed its inhibition on NSCLC cell proliferation and its synergy with chemotherapeutic cytotoxicity, while COX-2 inhibitor celecoxib treatment boosted such effects. Lumbrokinase combined with bevacizumab, paclitaxel, or vincristine inhibited the xenograft growth of NSCLC cells in mice more significantly than a single treatment. In conclusion, lumbrokinase inhibited NSCLC survival and sensitized NSCLC cells to bevacizumab or chemotherapeutics treatment by targeted down-regulation of BPTF/VEGF signaling and inactivation of NF-κB/COX-2 signaling, respectively. The combinational applications of lumbrokinase with bevacizumab or chemotherapeutics are expected to be developed as promising candidate therapeutic strategies to improve the efficacy of the original monotherapy in anti-NSCLC.

[PMID: 37439684 DOI: 10.1002/jbt.23456] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 05/15/2023] [Accepted: 07/04/2023] [Indexed: 07/14/2023]
Abstract
We aim to study the inhibitory effect of alkaline serine protease (ASPNJ) on lymphocytic leukemia Jurkat cells and its related mechanism through examining the expression of membrane proteins or membrane-associated proteins. MTT assay and trypan blue staining were used to detect the inhibitory effect of ASPNJ on the proliferation and growth of Jurkat cells. Wright-Giemsa staining was used to observe the effect of ASPNJ on the morphology of Jurkat cells. The effect of ASPNJ on Jurkat cell apoptosis was detected by flow cytometry. Two-dimensional electrophoresis-mass spectrometry (2-DE-MS) was used to detect and identify the differentially expressed proteins of Jurkat cells treated with ASPNJ (4 μg/mL, 3 h), of which three were selected and verified by Western blot. ASPNJ significantly inhibited the proliferation of leukemia cells (Raji, U937, and Jurkat), caused obvious morphological changes, and induced apoptosis of Jurkat cells. ASPNJ also increased the sensitivity of Jurkat cells to vincristine (VCR). Seven differentially expressed proteins were obtained through 2DE-MS, of which Peroxiredoxin-6 (PRDX6), Calcium-binding protein (CHP1), and 40S ribosomal protein SA (RPSA) were validated. ASPNJ can cause significant toxic effects on Jurkat cells and enhance the effects of VCR. The mechanism of action of ASPNJ on Jurkat cells may be related to differentially expressed proteins such as PRDX6. This study provides a new experimental basis and direction for antileukemia research.

Abstract
BACKGROUND Lumbrokinase derived from earthworms, Lumbricus rubellus is known to have fibrinolytic enzymes that have potential as therapeutic drugs due to its ability to dissolve fibrin. The current study is aimed to purify the Lumbrokinase from L. rubellus and identify its protein component. METHODS Water extract of local earthworm Lumbricus rubellus revealed several proteins. Therefore, to identify its protein component, purification through HiPrep DEAE fast flow and proteomic analysis were conducted prior to identifications. A combination of two-dimension gel electrophoresis (2DE) and electrospray ionization mass spectrometry analysis was used to identify the purified fractions. RESULTS The purified fractions contain five protein bands, namely F25-1, F25-2, F85-1, F85-2, and F85-3, which displayed strong fibrinogenolytic activity. F25 fractions showed fibrinogenolytic activity of 974.85 U/mg, while F85 fractions showed higher activity of 1,484.11 U/mg. Fractions F85-1, F85-2, and F85-3 showed molecular weights of 42.6 kDa, 27.03 kDa, and 14 kDa, respectively and were identified as Lumbrokinase iso-enzymes. CONCLUSION This preliminary study indicates that the F25 and F85 fractions are similar to published fibrinolytic protease-1 and lumbrokinase, respectively, in terms of their amino acid sequence.

Abstract
Earthworms have long been used as traditional medicine. The purposes of this research were to create bioactive peptides from the unique Amynthas arenulus earthworm (PAAEs) and test their potentials on liver cancer bioprophylactic activity, antioxidant, oxidative stress protection, and immune cell activation. This earthworm had a high protein content ratio, at 55.39%. Besides, PM 35 is one out of 58 bacteria isolated from the earthworm carcasses that exhibited the highest protease and yield protein production which was chosen as the protease-producing bacteria to hydrolyze the protein. The genera were identified by 16S rRNA and 16S–23S rRNA comparison and confirmed as Bacillus velezensis PM 35. The response surface methodology was applied to optimize these hydrolysis parameters, i.e., the enzyme/substrate (E/S) concentration ratio [1%–3% (v/v)] and time (1–3 h) of the hydrolyzing earthworm’s proteins. The optimal hydrolyzing conditions were 3% (v/v) of E/S concentration ratio and 3 h of hydrolysis time, which found protein-hydrolysate yield (24.62%) and degree of hydrolysis (85.45%) as the highest. After being challenged in the gastrointestinal tract-resistant model, these PAAEs (MW <3 and 3–5 kDa) induced liver cancer cell (HepG2) death via apoptotic action modes (cell morphological change and DNA fragmentation). The PAAEs (MW <3 kDa) exhibited significant antioxidant activity via DPPH, ABTS, and FRAP with IC50 values of 0.94, 0.44, and 6.34 mg/ml, respectively. The PAAEs (MW < 3 kDa) were non-cytotoxic and protected the mouse fibroblast cells (L929) against oxidative stress. These PAAEs (MW < 3 kDa, 0.2 mg/ml) stimulated the B lymphocytes (122.3%), and T lymphocytes (126.7%) proliferation. This research suggests that PAAEs can be used in a variety of applications, especially in the food and pharmaceutical industries.

Abstract
The functioning of soil ecosystems greatly depends on the interactions occurring between soil biota communities. It is well known that earthworms are an important soil component that substantially affects its function, including their meaningful impact on the development of different phytopathogenic soil fungi. Phytopathogenic fungi are responsible for crop disease and cause great economic damage. It has previously been established that earthworms’ coelomic fluid can suppress the growth of phytopathogenic fungi, but the exact molecular mechanism is unknown. The present study aimed at broadening the proof of this observed phenomenon by investigating the effects of the coelomic fluid extract of three different earthworm species (Eisenia andrei, Dendrobaena veneta and Allolobophora chlorotica) on the growth of six different phytopathogenic fungi species (Berkeleyomyces basicola, Fusarium culmorum, Globisporangium irregulare, Rhizoctonia solani, Macrophomina phaseolina, and Sclerotinia sclerotiorum). Coelomic fluid extract was obtained by electrostimulation or usage of extraction buffer (only in case of A. chlorotica) and prepared in three different concentrations by diluting the obtained coelomic fluid with physiological saline. The coelomic fluid extract of the three investigated earthworm species had an inhibitory effect on the growth of all six phytopathogenic fungi species. The greatest inhibitory effect was achieved with the E. andrei coelomic fluid extract reducing the growth of R. solani fungi. The findings of this research confirm the antifungal activity of coelomic fluid obtained from earthworm species belonging to different ecological categories and may be of potential use in crop protection against phytopathogenic fungi.

Abstract
Pheretima posthuma (Vaillant, 1868), a native earthworm of Pakistan and Southeast Asia, has wide utilization in vermicomposting and bioremediation process. In this study, P. posthuma coelomic fluid (PCF) and body paste (PBP) was evaluated as antibacterial agent against ampicillin (AMP) resistant five Gram positive and four Gram negative clinical isolates. The antibacterial effect of different doses (i.e. 25-100 µg/ml) of PCF and PBP along with AMP and azithromycin (AZM) (negative and positive controls, respectively) were observed through disc diffusion and micro-dilution methods. All nine clinical isolates were noticed as AMP resistant and AZM sensitive. Antibacterial effects of PCF and PBP were dose dependent and zone of inhibitions (ZI) against all clinical isolates were between 23.4 ± 0.92 to 0 ± 00 mm. The sensitivity profile of PCF and PBP against clinical isolates was noticed as 44.44 and 55.56%, respectively. Both PCF and PBP showed bacteriostatic (BTS) action against S. aureus, S. pyogenes, K. pneumonia, N. gonorrhoeae. Moreover, the cumulative BTS potential of PCF and PBP against all isolates was 66.67 and 55.56%, respectively. The MICs of PCF and PBP were ranged from 50-200 µg/ml against selected isolates. The bacterial growth curves indicated that PCF and PBP inhibited the growth of all isolates at their specific MIC concentrations. However, PBP has better antibacterial potential compared to PCF against selected isolates. Therefore, it is concluded that both PCF and PBP of P. posthuma possess antibacterial and BTS potential against ampicillin resistant clinical isolates. This organism might be considered as a second choice of antibacterial agents and can further be utilized in pharmaceutical industries for novel drug manufacturing by prospecting bioactive potential agents.

Abstract
Tissue regeneration and wound healing are still serious clinical complications globally and lack satisfactory cures. Inspired by the impressive regeneration ability of the post-injury earthworms and their widely accepted medicinal properties, we screened and identified a novel collagen-like peptide from the amputated earthworms using high-throughput techniques, including transcriptomics, proteomics, and mass spectrum. The identified collagen-like peptide col4a1 was cloned and expressed to comprehensively investigate the wound healing effect and underlying mechanism. It exerted significant effects on wound healing both in vitro and in vivo, including enhanced viability, proliferation, migration of fibroblasts, granulation, and collagen deposition. Moreover, the col4a1 functioned via binding with integrin α2β1 and upregulating the RAS/MAPK signaling pathway. This work demonstrates that the novel collagen-like peptide col4a1 obtained from the amputated earthworms enables enhanced wound healing and provides new opportunities for wound care.

Abstract
Ulcerative colitis is a major risk factor that increases the occurrence of colorectal cancer. In colorectal cancer due to colitis, intestinal inflammation plays an important role which causes DNA damage. The aim of this study is to investigate the anticancer effect of coelomic fluid of Eisenia fetida (CFEF) and cetuximab combinations. Colitis associated colon cancer was induced in BALB/c mice by DSS/AOM. The mice were randomly divided into six groups: group 1 received vehicle (control), groups 2–6 received DSS/AOM, groups 3–5 received cetuximab + CFEF (30, 60, or 120 mg/kgBW), and group 6 received CFEF only. After the 12th week of treatments, the colon tissues were removed for histological examination and immune-fluorescence. Intestinal Epithelial Cells (CECs) were analyzed by flow cytometer. Administration of CFEF significantly decreased the severity of DSS/AOM-induced CAC in a dose-dependent manner. The combinations of CFEF-cetuximab were revealed by histological change. The CFEF significantly reduced the severity scores (P < 0.05). The combinations of CFEF-cetuximab significantly inhibited K-Ras and vimentin expressions, whereas the percentage of RUNX3 significantly increased in CECs. The increasing of RUNX3 could prevent EMT, so that it can decrease K-Ras and vimentin to suppressed cell invasion and migration by CFEF. Our results suggest that CFEF has the therapeutic potential to CAC.

Abstract
Great efforts have been made to explore the potential treatment for cancers, and the most common therapies include surgery, chemotherapy and radiotherapy. As an alternative medication, earthworms have drawn increased attention considering its abundance in resource, easy access and minor side effects compared to traditional therapies. However, few studies had focused on the antitumor effect of earthworm-derived components. The purpose of this study is to investigate whether earthworm extract has an effect on tumor cell apoptosis and growth. Earthworm extract (EE) was purified through multiple steps of centrifugation and chromatography. Mice were inoculated with ascitic fluid derived from mice inoculated with S180 sarcoma tumor cells and fed orally with different amounts of EE for 25 days. Tumor samples were analyzed for size and cell apoptosis. And we found that the weight and sizes of tumor decreased gradually as the amount of EE administered increased. More apoptotic cells and lowered level of lactate dehydrogenase (LDH), a biomarker of tumor invasiveness, was detected in EE-treated group than the untreated group. Our results suggested that EE could dramatically promote tumor apoptosis and reduce tumor size in vivo, suggesting a novel alternative therapy for cancer patients.

Abstract
It is known that earthworm coelomic fluid (CF) can affect not only cancer but also normal cells. The study demonstrated that the CF of the earthworm Dendrobaena veneta exhibited cytotoxicity against A549 lung cancer cells but did not toward the bronchial epithelial cell line BEAS-2B. The selective effect on the tumor cells was achieved after a short-term CF heat pre-treatment at 70 °C. The cytotoxic effect of the CF was time- and concentration-dependent. The CF noticeably decreased the viability and affected the morphology of the A549 cells. Scanning electron microscopy revealed a different degree of destruction of the nucleus and cytoplasm of A549 cells. As determined by atomic force microscopy, the cell surface roughness increased while the cell stiffness was reduced upon the CF treatment. A twofold increase in the caspase 3, 4, 5, and 10 levels was observed in the A549 cells after the incubation with the CF. The results obtained by flow cytometry using Annexin V confirmed the proapoptotic effect of the earthworm CF on A549 lung cancer cells. The D. veneta CF and active fraction obtained with cytotoxicity toward A549 lung cancer is an interesting and promising preparation for further biological, chemical, and biomedical research.

Abstract
The influence of lecithin from egg yolk (LE) on calcium carbonate (CaCO3) biomineralization was investigated. In the present study, spherical CaCO3 particles were synthesized via coprecipitation in the presence of LE. LE multilamellar liposomes were first tuned by sonication to provide better control over the nucleation of CaCO3. Subsequently, monodisperse microspheres ~2 µm in size were generated by controlling the aggregation and growth of CaCO3 under appropriate concentrations of LE. In contrast to unstable vaterite, the microspheres generated in aqueous solution remained stable for at least 10 days without transforming into calcite, due to the strong interaction between the LE and calcium ions. The microspheres as drug carriers of doxorubicin (DOX) were assessed and were observed to have a good encapsulation efficiency, sustained drug release without a burst release and notable pH sensitivity. In addition, in vivo tumor inhibition examination demonstrated that DOX‑loaded CaCO3 microspheres formulation had more superior efficacy to significantly restrain tumor growth. These novel LE/CaCO3 hybrids may provide novel options for various biomedical applications.

Abstract
Salidroside is one of the most potent compounds extracted from the plant Rhodiola rosea, and its cardiovascular protective effects have been studied extensively. However, the role of salidroside in human ovarian carcinoma remains unknown. The aim of the current study was to investigate the effects of salidroside on the proliferation and apoptosis of SKOV3 and A2780 cells using MTT assay and acridine orange/ethidium bromide staining. Salidroside activated caspase-3 and upregulated the levels of apoptosis-inducing factor, Bcl-2-associated X and Bcl-2-associated death promoter (Bad) proteins. Furthermore, salidroside downregulated the levels of Bcl-2, p-Bad and X-linked inhibitor of apoptosis proteins. Salidroside activated the caspase-dependent pathway in SKOV3 and A2780 cells, upregulating p53, p21Cip1/Waf1 and p16INK4a. These results suggest that the p53/p21Cip1/Waf1/p16INK4a pathway may serve a key function in salidroside-mediated effects on SKOV3 and A2780 cells. The current findings indicate that salidroside may be a promising novel drug candidate for ovarian cancer therapy.

Abstract
Nereis active protease (NAP) is a novel fibrinolytic active serine protease from the polychaete Nereis virens. In this study, NAP was purified from Nereis virens and the effects of NAP on human lung cancer cells were investigated. Our results indicated that NAP inhibited the proliferation and induced apoptosis of H1299 cells in a time- and dose-dependent manner. The loss of mitochondrial membrane potential, the activation of Bax and cleaved-caspase 3/9, the release of cytochrome C, and the suppression of Bcl-2 and poly-ADP ribose polymerase were observed in NAP-treated H1299 cells by flow cytometry and Western blotting. Moreover, the expression levels of Bax and Bcl-2 mRNA were determined by real-time quantitative polymerase chain reaction and the Bax/Bcl-2 expression ratio was increased in the NAP-treated cell lines. The results indicated that NAP-induced apoptosis may be related to mitochondria mediated apoptosis and occurs through caspase-dependent pathways. Then, the effects of NAP on tumor growth in animal models were observed, where 5 or 10 mg/kg of NAP noticeably reduced tumor volume and weight and increased apoptosis as determined by Western blotting when compared to the negative control group. Therefore, our findings suggest that NAP could be a hopeful anticancer medicine for its propensity to inhibit growth and induce of apoptosis in human lung cancer cells.

Abstract
The potential application of anti-inflammatory and analgesic compounds in medication and therapeutic care have become of increasing interest. We purified and characterized two novel analgesic and anti-inflammatory peptides, VQ-5 and AQ-5, from the coelomic fluid of the earthworm (Eisenia foetida). Their primary structures were determined as VSSVQ and AMADQ, respectively. Both peptides, especially AQ-5, exhibited analgesic activity in mouse models of persistent neuropathic pain and inflammation. AQ-5 also inhibited tumor necrosis factor alpha and cyclooxygenase-2 production. The mitogen-activated protein kinase signaling pathway, which is involved in analgesic and anti-inflammatory functions, was inhibited by AQ-5. Thus, the analgesic and anti-inflammatory effects of these peptides, especially AQ-5, demonstrated their potential as candidates for the development of novel analgesic medicines.

Abstract
Ovarian carcinoma is a common malignant disease worldwide with a poor therapeutic response. The present study investigated the effects of Na7CrCuW11O39.16H2O (CrCuW11) on ovarian cancer cell growth and investigated the mechanisms underlying its actions. The effects of CrCuW11 on cell viability and apoptosis were measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, acridine orange/ethidium bromide staining and electron microscopy in human ovarian cancer SKOV3 cells. The expression of bcl-2-like protein 4 (Bax), B-cell lymphoma 2 (Bcl-2), cytochrome c, phosphorylated (p)-p38 and p38 was determined by western blot analysis. Caspase-3 activity was measured by caspase-3 activity kit. CrCuW11 concentrations of 1.87×10-3 mol. l-1 at 12 h reduced viability induced apoptosis in SKOV3 cells in a concentration-and time-dependent manner. Forced expression of CrCuW11 upregulated the expression of certain proteins (Bax, cytochrome c, and p-p38), and downregulated Bcl-2 protein expression. Furthermore, CrCuW11 also enhanced caspase-3 activity. The p38 inhibitor SB203580 was able to inhibit the activity of CrCuW11. Caspase-3 and p38 signaling pathways were associated with CrCuW11-regulated multiple targets involved in SKOV3 cell proliferation. Therefore, the results of the present study indicated that CrCuW11 may be used as a novel clinical drug for the treatment of ovarian cancer.

Abstract
Lung cancer is the leading cause of cancer-associated mortality worldwide. The present study investigated the effects of K9(C4H4FN2O2)2Nd(PW11O39)2·25H2O (FNdPW), a chemically synthesized polyoxometalate that contains rare earth elements, on lung cancer growth, and explored the mechanism underlying its actions. The effects of FNdPW on the cell viability and apoptosis of human lung cancer A549 cells were measured using MTT assay, acridine orange/ethidium bromide staining and electron microscopy. The expression of apoptosis-related proteins, including B-cell lymphoma (Bcl)-2-associated death promoter (Bad), phosphorylated (p)-Bad, X-linked inhibitor of apoptosis (XIAP), apoptosis-inducing factor (AIF), Bcl-2-associated X protein (Bax) and Bcl-2, was determined by western blotting. Caspase-3 activity was measured using a caspase-3 activity kit. After 72 h of incubation, FNdPW reduced cell viability and induced apoptosis in A549 cells in a concentration- and time-dependent manner. FNdPW upregulated the pro-apoptotic Bad and Bax proteins, and downregulated the anti-apoptotic p-Bad, Bcl-2 and XIAP proteins. Furthermore, FNdPW also enhanced caspase-3 activity and increased the protein level of AIF in A549 cells, which was independent of the caspase-3 pathway. These events were associated with the regulation exerted by FNdPW on multiple targets involved in A549 cell proliferation. Therefore, FNdPW may be a novel drug for the treatment of lung cancer.

Abstract
Enzymes are the most versatile molecules in the biological world. These amazing molecules play an integral role in the regulation of various metabolic pathways and physiology subsequently. Promiscuity of an enzyme is the capacity to catalyze additional biochemical reactions besides their native one. Catalytic promiscuity has shown great impact in enzyme engineering for commercial enzyme and therapeutics with natural or engineered catalytic promiscuity. The earthworm serine protease (ESP) is a classic example of enzyme promiscuity and studied for its therapeutic potential over the last few decades. The ESP was reported for several therapeutic properties and fibrinolytic activity has been much explored. ESP, a complex enzyme exists as several isoforms of molecular weight ranging from 14 to 33 kDa. The fibrinolytic capacity of the enzyme has been studied in different species of earthworm and molecular mechanism is quite different from conventional thrombolytics. Cytotoxic and anti-tumor activities of ESP were evaluated using several cancer cell lines. Enzyme had shown tremendous scope in fighting against plant viruses and microbes. ESP is also reported for anti-inflammatory activity and anti-oxidant property. Apart from these, recently, ESP is reported for DNase activity. The daunting challenge for researchers is to understand the molecular mechanism for such diverse properties and possibility of enzyme promiscuity. This review emphasizes molecular mechanism of ESP governing various biochemical reactions. Further, the concept of enzyme promiscuity in ESP towards development of novel enzyme based drugs has been reviewed in this study.

Abstract
Bone cell activities are very important in bone remodeling. This study investigates the effects of lumbrokinase on bone cell activities in cultures. Moreover, a biodegradable composite (GGT) containing genipin-crosslinked gelatin and β-tricalcium phosphate was prepared to carry lumbrokinase (GGTLK). Rat calvarial bone defects were filled with GGT and GGTLK composites. Bone healing was monitored in vivo by bioluminescence imaging and micro-CT. Lumbrokinase was found to have a dose-dependent effect on bone cell activities. Low concentrations (<1μg/ml) of lumbrokinase increased the viability, total alkaline phosphatase activity and mobility of osteoblasts, the number of total calcified nodules and the expression of osteopontin and osteocalcin; however, they considerably reduced the total tartrate-resistant acid phosphatase activity of osteoclasts. IVIS images revealed a stronger fluorescent signal in GGTLK-treated animals than in GGT-treated animals. Micro-CT analysis revealed that GGTLK induced more new bone formation than did GGT. These observations suggest that lumbrokinase released from GGTLK composite can enhance bone tissue regeneration.

Abstract
The widely-used Chinese medicinal herb Hypericum japonicum, also known as Hypericum japonicum Thunb or Tianjihuang, displays potent anti-carcinogenic effects against liver cancer. However, the molecular mechanism underlying the therapeutic effects of Hypericum japonicum remains to be elucidated. The present study investigated the in vivo efficacy of ethyl acetate extract of Hypericum japonicum (EAEHJ) against tumor growth in an H22 cell-bearing liver cancer mouse model. Treatment with EAEHJ significantly reduced tumor weight, but had no effect on murine body weight. The results of the present study also showed that EAEHJ induced H22 cell apoptosis in vivo. In addition, the anti-carcinogenic effects of EAEHJ were investigated in vitro. The results of the present study demonstrate that both phospholipid asymmetry in the plasma membrane and mitochondrial membrane potential were deregulated in HepG2 human hepatoma cells, following treatment with EAEHJ. Treatment with EAEHJ also increased the ratio of pro-apoptotic B-cell lymphoma 2 (Bcl-2)-associated X protein (Bax) to anti-apoptotic Bcl-2, and activated the caspase-9 signaling pathway. These results suggest that EAEHJ is able to trigger the apoptosis of liver cancer cells via the mitochondria-dependent pathway.

Abstract
The shiitake mushroom Lentinula edodes has health benefits and is used to treat various diseases due to its immunomodulatory and antineoplastic properties. In the present study, the Latcripin-13 domain, isolated from L. edodes, was expressed in Escherichia coli Rosetta-gami(DE3) in the form of inclusion bodies. The Latcripin-13 domain was purified by Ni-His affinity chromatography with high purity and refolded by urea gradient dialysis. The product showed biological activity in A549 cells, a human lung cancer cell line, by flow cytometry and the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) method. The MTT assay and the flow cytometry results revealed that there was a great difference between the Latcripin-13 domain-treated group and the control group (p<0.05). Similarly, cell apoptosis observed by transmission electron microscopy (TEM) supported the flow cytometry results. This work demonstrated that the Latcripin-13 domain can induce apoptosis of A549 cells, which will bring new insights into the development of new antitumor drugs in the future.

Abstract
Arenicola cristata, a marine annelid, is a well-known and prized traditional Chinese medicine. However, the serine protease gene of A. cristata has not been cloned yet. In this study, a novel protease of A. cristata was cloned, sequenced, and expressed in Escherichia coli, and the functions of this recombinant protease were also investigated. The whole complementary DNA (cDNA) of this novel protease was of 980 bp in length and consisted of an open reading frame of 861 bp encoding 286 aa. Sequence analysis of the deduced amino acid sequence revealed that the protease belongs to the serine protease family. The active enzyme of the proposed A. cristata protease is composed of a signal peptide, a propeptide, and a mature polypeptide. The molecular weight of the recombinant mature protein was ~26 kDa after over-expression in E. coli. The recombinant protein significantly inhibited cell growth and induced cell apoptosis of esophageal squamous cell carcinoma (ESCC) in vitro, and reduced tumorigenicity in vivo. Furthermore, administration of the recombinant protein led to the activation of caspase-9 as well as down-regulation of Mcl-1 and Bcl-2. Taken together, our findings indicated that the recombinant serine protease of A. cristata could inhibit ESCC cell growth by mitochondrial apoptotic pathway and might act as a potential pharmacological agent for ESCC therapy.

Abstract
The polysaccharide-protein complex (PPC) isolated from metabolites of gut bacteria Raoultella ornithinolytica from Dendrobaena veneta earthworms exhibits activity against Candida albicans, in breast ductal carcinoma (line T47D) and in the endometrioid ovarian cancer line (TOV-112D) in vitro. The action against C. albicans was analyzed using light, SEM, TEM, and AFM microscopes. The changes observed indicated two directions of the action of the complex, that is, disturbance of metabolic activity and cell wall damage. The PPC is an adhesion-promoting complex inducing death of C. albicans cells by necrosis. Owing to its significant effect on C. albicans, the complex is a promising source of antifungal compounds. The PPC showed a minimal cytotoxic effect against human skin fibroblasts; however, the cytotoxicity against the T47D line was determined at 20% and 15% against the TOV-112D line. The action of the PPC against the T47D line exerted a cytopathic effect, whereas in the TOV-112D line, it caused a reduction in the cell number. The PPC induced death of tumor cells by apoptosis and necrosis. In view of the negligible cytotoxicity on fibroblasts, the PPC will be subjected to chemical modifications to increase its antitumor activity for prospective medical applications.

Abstract
NPC (nasopharyngeal carcinoma) is a common malignancy in southern China without defined aetiology. Recent studies have shown that TGFBR3 (transforming growth factor type III receptor, also known as betaglycan), exhibits anticancer activities. This study was to investigate the effects of TGFBR3 on NPC growth and the mechanisms for its actions. Effects of TGFBR3 overexpression on cell viability and apoptosis were measured by MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide], AO/EB (acridine orange/ethidium bromide) staining and electron microscopy in human NPC CNE-2Z cells. The expression of apoptosis-related proteins, p-Bad, Bad, XIAP (X-linked inhibitor of apoptosis), AIF (apoptosis-inducing factor), Bax and Bcl-2, was determined by Western blot or immunofluorescence analysis. Caspase 3 activity was measured by caspase 3 activity kit and [Ca2+]i (intracellular Ca2+ concentration) was detected by confocal microscopy. Transfection of TGFBR3 containing plasmid DNA at concentrations of 0.5 and 1 μg/ml reduced viability and induced apoptosis in CNE-2Z in concentration- and time-dependent manners. Forced expression of TGFBR3 up-regulated pro-apoptotic Bad and Bax protein, and down-regulated anti-apoptotic p-Bad, Bcl-2 and XIAP protein. Furthermore, transient overexpression of TGFBR3 also enhanced caspase 3 activity, increased [Ca2+]i and facilitated AIF redistribution from the mitochondria to the nucleus in CNE-2Z cells, which is independent of the caspase 3 pathway. These events were associated with TGFBR3-regulated multiple targets involved in CNE-2Z proliferation. Therefore transient overexpression of TGFBR3 may be a novel strategy for NPC prevention and therapy.

Abstract
Schwann cell proliferation is critical for the regeneration of injured nerves. Dilongs are widely used in Chinese herbal medicine to remove stasis and stimulate wound-healing functions. Exactly how this Chinese herbal medicine promotes tissue survival remains unclear. The aim of the present study was to investigate the molecular mechanisms by which Dilong promote neuron regeneration. Our results show that treatment with extract of Dilong induces the phosphorylation of the insulin-like growth factor-I (IGF-I)-mediated phosphatidylinositol 3-kinase/serine-threonine kinase (PI3K/Akt) pathway, and activates protein expression of cell nuclear antigen (PCNA) in a time-dependent manner. Cell cycle analysis showed that G1 transits into the S phase in 12–16 h, and S transits into the G2 phase 20 h after exposure to earthworm extract. Strong expression of cyclin D1, cyclin E and cyclin A occurs in a time-dependent manner. Small interfering RNA (siRNA)-mediated knockdown of PI3K significantly reduced PI3K protein expression levels, resulting in Bcl2 survival factor reduction and a marked blockage of G1 to S transition in proliferating cells. These results demonstrate that Dilong promotes the proliferation and survival of RSC96 cells via IGF-I signaling. The mechanism is mainly dependent on the PI3K protein.

Abstract
The medicinal value of earthworm has been widely known since the history of Asian ancient medicine. This present study aims to determine the mechanism of action and effect of a standardized extract of Lumbricus rubellus named as DLBS1033. The fibrinogen degradation, antiplatelet aggregation, and ex vivo antithrombotic assay using human blood were performed to study antithrombotic activity. Fibrin plate and clot lysis assay were also done to examine thrombolytic properties. DLBS1033 was found to possess fibrinogenolytic activity on α-, β-, and γ-chain of fibrinogen. It also induced antiplatelet aggregation and prolonged blood clotting time, which further confirmed its antithrombotic properties. In addition, thrombolytic properties of DLBS1033 were shown with its fast and long-acting fibrinolytic activity, as well as its effective blood clot lysis activities. In conclusion, DLBS1033 conferred antithrombotic and thrombolytic action which could be used as a safe and promising oral thrombolytic drug.

INTRODUCTION Earthworms respond to microbial infection through cellular and humoral defense mechanisms such as antimicrobial protein secretions. Most of the humoral defense proteins are synthesized in the skin itself. MATERIALS AND METHODS In the present study, a dried powder was prepared from two indigenous earthworms (Lampito mauritii and Perionyx excavatus) and tested against two gram-positive bacteria (Staphylococcus aureus and Staphylococcus epidermidis) and five gram-negative bacteria (Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Proteus vulgaris, and Pseudomonas aeruginosa). RESULTS The dried earthworm powder of two species shows a strong antibacterial activity against the S. aureus, P. mirabilis, and P. aeruginosa bacterial strains. Of these, the 60 μg/mL/disc of P. excavatus earthworm powder shows more activity than the L. mauritii.

Schwann Cell Migration Induced by Earthworm Extract via Activation of PAs and MMP2/9 Mediated through ERK1/2 and p38. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2011; 2011:395458.

Abstract
The earthworm, which has stasis removal and wound-healing functions, is a widely used Chinese herbal medicine in China. Schwann cell migration is critical for the regeneration of injured nerves. Schwann cells provide an essentially supportive activity for neuron regeneration. However, the molecular migration mechanisms induced by earthworms in Schwann cells remain unclear. Here, we investigate the roles of MAPK (ERK1/2, JNK and p38) pathways for earthworm-induced matrix-degrading proteolytic enzyme (PAs and MMP2/9) production in Schwann cells. Moreover, earthworm induced phosphorylation of ERK1/2 and p38, but not JNK, activate the downstream signaling expression of PAs and MMPs in a time-dependent manner. Earthworm-stimulated ERK1/2 and p38 phosphorylation was attenuated by pretreatment with U0126 and SB203580, resulting in migration and uPA-related signal pathway inhibition. The results were confirmed using small interfering ERK1/2 and p38 RNA. These results demonstrated that earthworms can stimulate Schwann cell migration and up-regulate PAs and MMP2/9 expression mediated through the MAPK pathways, ERK1/2 and p38. Taken together, our data suggests the MAPKs (ERK1/2, p38)-, PAs (uPA, tPA)-, MMP (MMP2, MMP9) signaling pathway of Schwann cells regulated by earthworms might play a major role in Schwann cell migration and nerve regeneration.

Expression, purification, and characterization of recombinant lumbrokinase PI239 in Escherichia coli. Protein Expr Purif 2009; 69:198-203. [PMID: 19716893 DOI: 10.1016/j.pep.2009.08.013] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2009] [Revised: 08/20/2009] [Accepted: 08/24/2009] [Indexed: 11/21/2022]
Abstract
Lumbrokinase (LK) is an important fibrinolytic enzyme derived from earthworms. It has been found that LK is composed of a group of isoenzymes. To construct and express the mature peptide of LK PI239 in Escherichia coli, we amplified and optimized the gene of LK which was then cloned into the prokaryotic expression vector pET-22b(-). The recombinant LK (rLK) protein was expressed as inclusion bodies and we have developed a purification process of rLK from these inclusion bodies. A step-down urea concentration strategy was applied to the rLK renaturation process. The purified and renatured rLK apparently ameliorated the conditions of the model thrombosis rats used, and may be developed into a therapeutic agent for thrombotic-associated diseases.

The phytoestrogen genistein affects zebrafish development through two different pathways. PLoS One 2009; 4:e4935. [PMID: 19319186 PMCID: PMC2655710 DOI: 10.1371/journal.pone.0004935] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2008] [Accepted: 02/10/2009] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Endocrine disrupting chemicals are widely distributed in the environment and derive from many different human activities or can also be natural products synthesized by plants or microorganisms. The phytoestrogen, genistein (4', 5, 7-trihydroxy-isoflavone), is a naturally occurring compound found in soy products. Genistein has been the subject of numerous studies because of its known estrogenic activity. METHODOLOGY/PRINCIPAL FINDINGS We report that genistein exposure of zebrafish embryos induces apoptosis, mainly in the hindbrain and the anterior spinal cord. Timing experiments demonstrate that apoptosis is induced during a precise developmental window. Since adding ICI 182,780, an ER antagonist, does not rescue the genistein-induced apoptosis and since there is no synergistic effect between genistein and estradiol, we conclude that this apoptotic effect elicited by genistein is estrogen-receptors independent. However, we show in vitro, that genistein binds and activates the three zebrafish estrogen receptors ERalpha, ERbeta-A and ERbeta-B. Furthermore using transgenic ERE-Luciferase fish we show that genistein is able to activate the estrogen pathway in vivo during larval stages. Finally we show that genistein is able to induce ectopic expression of the aromatase-B gene in an ER-dependent manner in the anterior brain in pattern highly similar to the one resulting from estrogen treatment at low concentration. CONCLUSION/SIGNIFICANCE TAKEN TOGETHER THESE RESULTS INDICATE THAT GENISTEIN ACTS THROUGH AT LEAST TWO DIFFERENT PATHWAYS IN ZEBRAFISH EMBRYOS: (i) it induces apoptosis in an ER-independent manner and (ii) it regulates aromatase-B expression in the brain in an ER-dependent manner. Our results thus highlight the multiplicity of possible actions of phytoestrogens, such as genistein. This suggests that the use of standardized endpoints to study the effect of a given compound, even when this compound has well known targets, may carry the risk of overlooking interesting effects of this compound.
