Cordyceps militaris is used widely as a traditional medicine in East Asia. Although a few studies have attempted to elucidate the anticancer activities of C. militaris, the precise mechanism of C. militaris therapeutic effects is not fully understood. We examined the anticancer activities of C. militaris ethanolic extract (Cm-EE) and its cellular and molecular mechanisms. For this purpose, a xenograft mouse model bearing murine T cell lymphoma (RMA) cell-derived cancers was established to investigate in vivo anticancer mechanisms. MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay, immunoblotting analysis, and flow cytometric assay were employed to check in vitro cytotoxicity, molecular targets, and proapoptotic action of Cm-EE. Interestingly, cancer sizes and mass were reduced in a C. militaris-administered group. Levels of the phosphorylated forms of p85 and AKT were clearly decreased in the group administered with Cm-EE. This result indicated that levels of phosphoglycogen synthase kinase 3β (p-GSK3β) and cleaved caspase-3 were increased with orally administered Cm-EE. In addition, Cm-EE directly inhibited the viability of cultured RMA cells and C6 glioma cells. The number of proapoptotic cells was significantly increased in a Cm-EE treated group compared with a control group. Our results suggested that C. militaris might be able to inhibit cancer growth through regulation of p85/AKT-dependent or GSK3β-related caspase-3-dependent apoptosis.

Extracorporeal Shock Wave

Extracorporeal Shock Wave Therapy (ESWT) is used clinically in various disorders including chronic wounds for its pro-angiogenic, proliferative, and anti-inflammatory effects. However, the underlying cellular and molecular mechanisms driving therapeutic effects are not well characterized. Macrophages play a key role in all aspects of healing and their dysfunction results in failure to resolve chronic wounds. We investigated the role of ESWT on macrophage activity in chronic wound punch biopsies from patients with non-healing venous ulcers prior to, and two weeks post-ESWT, and in macrophage cultures treated with clinical shockwave intensities (150–500 impulses, 5 Hz, 0.1 mJ/mm2). Using wound area measurements and histological/immunohistochemical analysis of wound biopsies, we show ESWT enhanced healing of chronic ulcers associated with improved wound angiogenesis (CD31 staining), significantly decreased CD68-positive macrophages per biopsy area and generally increased macrophage activation. Shockwave treatment of macrophages in culture significantly boosted uptake of apoptotic cells, healing-associated cytokine and growth factor gene expressions and modulated macrophage morphology suggestive of macrophage activation, all of which contribute to wound resolution. Macrophage ERK activity was enhanced, suggesting one mechanotransduction pathway driving events. Collectively, these in vitro and in vivo findings reveal shockwaves as important regulators of macrophage functions linked with wound healing. This immunomodulation represents an underappreciated role of clinically applied shockwaves, which could be exploited for other macrophage-mediated disorders.

Macrophages, a major subset of innate immune cells, are main infiltrating cells in the kidney in lupus nephritis. Macrophages with different phenotypes exert diverse or even opposite effects on the development of lupus nephritis. Substantial evidence has shown that macrophage M2 polarization is beneficial to individuals with chronic kidney disease. Further, it has been reported that PD-1 ligands (PD-Ls) contribute to M2 polarization of macrophages and their immunosuppressive effects. Total glucosides of paeony (TGP), originally extracted from Radix Paeoniae Alba, has been approved in China to treat some autoimmune diseases. Here, we investigated the potentially therapeutic effects of TGP on lupus nephritis in a pristane-induced murine model and explored the molecular mechanisms regulating macrophage phenotypes. We found that TGP treatment significantly improved renal function by decreasing the urinary protein and serum creatinine, reducing serum anti-ds-DNA level and ameliorating renal immunopathology. TGP increased the frequency of splenic and peritoneal F4/80+CD11b+CD206+ M2-like macrophages with no any significant effect on F4/80+CD11b+CD86+ M1-like macrophages. Immunofluorescence double-stainings of the renal tissue showed that TGP treatment increased the frequency of F4/80+Arg1+ subset while decreasing the percentage of F4/80+iNOS+ subset. Importantly, TGP treatment increased the percentage of both F4/80+CD11b+PD-L1+ and F4/80+CD11b+PD-L2+ subsets in spleen and peritoneal lavage fluid as well as the kidney. Furthermore, TGP augmented the expressions of CD206, PD-L2 and phosphorylated STAT6 in IL-4-treated Raw264.7 macrophages in vitro while its effects on PD-L2 were abolished by pretreatment of the cells with an inhibitor of STAT6, AS1517499. However, TGP treatment did not affect the expressions of STAT1 and PD-L1 in Raw264.7 macrophages treated with LPS/IFN-γ in vitro, indicating a possibly indirect effect of TGP on PD-L1 expression on macrophages in vivo. Thus, for the first time, we demonstrated that TGP may be a potent drug to treat lupus nephritis by inducing F4/80+CD11b+CD206+ and F4/80+CD11b+PD-L2+ macrophages through IL-4/STAT6/PD-L2 signaling pathway.

Abstract Background: Silica nanoparticles (SiNPs) are found in environmental particulate matter and are proven to have adverse effects on fertility. The relationship and underlying mechanisms between miRNAs and apoptosis induced by SiNPs during spermatogenesis is currently ambiguous. Experimental design: The present study was designed to investigate the role of miRNA-450b-3p in the reproductive toxicity caused by SiNPs. In vivo, 40 male mice were randomly divided into control and SiNPs groups, 20 per group. The mice in the SiNPs group were administrated 20 mg/kg SiNPs by tracheal perfusion once every 5 days, for 35 days, and the control group were given the equivalent of a normal luminal saline. In vitro, spermatocyte cells were divided into 0 and 5 μg/mL SiNPs groups, after passaged for 30 generations, the GC-2spd cells in 5 μg/mL SiNPs groups were transfected with miRNA-450b-3p and its mimic and inhibitor. Results: In vivo, the results showed that SiNPs damaged tissue structures of testis, decreased the quantity and quality of the sperm, reduced the expression of miR-450b-3p, and increased the protein expressions of the MTCH2, BID, BAX, Cytochrome C, Caspase-9, and Caspase-3 in the testis. In vitro, SiNPs obviously repressed the viability and increased the LDH level and apoptosis rate, decreased the levels of the miR-450b-3p, significantly enhanced the protein expressions of the MTCH2, BID, BAX, Cytochrome C, Caspase-9, Caspase-3; while the mimic of miR-450b-3p reversed the changes induced by SiNPs, but inhibitor further promoted the effects induced by SiNPs.Conclusion: The result suggested that SiNPs could induce the spermatocyte apoptosis by inhibiting the miR-450b-3p expression to target promoting the MTCH2 resulting in activating mitochondrial apoptotic signaling pathways in the spermatocyte cells.

Polymeric nanoparticles were widely used as delivery vehicles for targeted delivery of anticancer drugs, because of their targeting property and versatility. Mitochondria are one of the important organelles that regulate the apoptosis of cancer cells and can be considered as a pivotal target for cancer treatment. A pH-responsive charge-reversal and mitochondrial targeting nanoparticles, Vitamin B6-oligomeric hyaluronic acid-dithiodipropionic acid-berberine (B6-oHA-SS-Ber), were prepared in this study. Ber is a lipophilic cation that was conjugated with oHA through disulfide bonds to produce mitochondria-targeted conjugates (oHA-SS-Ber). B6 was conjugated to oHA to obtain B6-oHA-SS-Ber and the two types of Cur-loaded nanoparticles (Cur-NPs) were formulated by the dialysis method. Due to pKa of B6, the charge they carried in the tumor tissue acidic microenvironment can be transferred from negative charge to positive charge, further targeting mitochondria. In our study, we successfully synthesized B6-HA-SS-Ber and characterized the structure by 1H-NMR. According to the results of transmission electron microscopy (TEM), we found that the B6-oHA-SS-Ber/Cur micelles could self-assembled in water to form spherical nanoparticles, with a hydrodynamic diameter of 172.9±13 nm. Moreover, in vitro cytotoxicity, cellular uptake, lysosome escape and mitochondrial distribution researches revealed the better effect of B6-oHA-SS-Ber/Cur micelles in comparison to oHA-SS-Ber/Cur. In vivo anticancer activities indicated that the B6-oHA-SS-Ber/Cur micelles exhibited effective inhibition of tumor growth.

Purpose. Hydroxytyrosol (HT) processes multiaspect pharmacological properties such as antithrombosis and antidiabetes. The aim of this study was to explore the antistherosclerotic roles and relevant mechanisms of HT. Methods. Male apoE-/- mice were randomly divided into 2 groups: the control group and the HT group (10 mg/kg/day orally). After 16 weeks, blood tissue, heart tissue, and liver tissue were obtained to detect the atherosclerotic lesions, histological analysis, lipid parameters, and inflammation. And the underlying molecular mechanisms of HT were also studied in vivo and in vitro. Results. HT administration significantly reduced the extent of atherosclerotic lesions in the aorta of apoE-/- mice. We found that HT markedly lowered the levels of serum TG, TC, and LDL-C approximately by 17.4% (p=0.004), 15.2% (p=0.003), and 17.9% (p=0.009), respectively, as well as hepatic TG and TC by 15.0% (p<0.001) and 12.3% (p=0.003), respectively, while inducing a 26.9% (p=0.033) increase in serum HDL-C. Besides, HT improved hepatic steatosis and lipid deposition. Then, we discovered that HT could regulate the signal flow of AMPK/SREBP2 and increase the expression of ABCA1, apoAI, and SRBI. In addition, HT reduced the levels of serum CRP, TNF-α, IL-1β, and IL-6 approximately by 23.5% (p<0.001), 27.8% (p<0.001), 18.4% (p<0.001), and 19.1% (p<0.001), respectively, and induced a 1.4-fold increase in IL-10 level (p=0.014). Further, we found that HT might regulate cholesterol metabolism via decreasing phosphorylation of p38, followed by activation of AMPK and inactivation of NF-κB, which in turn triggered the blockade of SREBP2/PCSK9 and upregulation of LDLR, apoAI, and ABCA1, finally leading to a reduction of LDL-C and increase of HDL-C in the circulation. Conclusion. Our results provide the first evidence that HT displays antiatherosclerotic actions via mediating lipid metabolism-related pathways through regulating the activities of inflammatory signaling molecules.

Human neutrophil elastase (HNE) is a serine protease that degrades matrix proteins. An excess of HNE may trigger several pathological conditions, such as psoriasis. In this work, we aimed to synthesize, characterize and formulate new HNE inhibitors with a 4-oxo-β-lactam scaffold with less toxicity, as well as therapeutic index in a psoriasis context. HNE inhibitors with 4-oxo-β-lactam scaffolds were synthesized and characterized by NMR, FTIR, melting point, mass spectrometry and elemental analysis. In vitro cytotoxicity and serine protease assays were performed. The compound with the highest cell viability (AAN-16) was selected to be incorporated in an emulsion (AAN-16 E) and in a microemulsion (AAN-16 ME). Formulations were characterized in terms of organoleptic properties, pH, rheology, droplet size distribution, in vitro drug release and in vivo psoriatic activity. All compounds were successfully synthesized according to analytical methodology, with good yields. Both formulations presented suitable physicochemical properties. AAN-16 E presented the most promising therapeutic effects in a murine model of psoriasis. Overall, new HNE inhibitors were synthesized with high and selective activity and incorporated into topical emulsions with potential to treat psoriasis.

The efficacy of the plant-derived polyphenol curcumin, in various aspects of health and wellbeing, is matter of public interest. An internet search of the term “Curcumin” displays about 12 million hits. Among the multitudinous information presented on partly doubtful websites, there are reports attracting the reader with promises ranging from eternal youth to cures for incurable diseases. Unfortunately, many of these reports are not based on scientific evidence, but they feed the desideratum of the reader for a “miracle cure”. This circumstance makes it very difficult for researchers, who work in a scientifically sound and evidence-based manner on the therapeutic benefits (or side effects) of curcumin, to demarcate their results from sensational reports that circulate in the web and in other media. This is only one of many obstacles making it difficult to pave curcumin’s way into clinical application; others are its nonpatentability and low economic usability. A further impediment comes from scientists who never worked with curcumin or any other natural plant-derived compound in their own labs. They have never tested these compounds in any scientific assay, neither in vitro nor in vivo; however, they claim, in a sometimes polemic manner, that everything that has so far been published on curcumin’s molecular effects is based on artefacts. The here presented Special Issue comprises a collection of five scientifically sound articles and nine reviews reporting on the therapeutic benefits and the molecular mechanisms of curcumin or of chemically modified curcumin in various diseases ranging from malignant tumors to chronic diseases, microbial infection, and even neurodegenerative diseases. The excellent results of the scientific projects that underlie the five original papers give reason to hope that curcumin will be part of novel treatment strategies in the near future—either as monotherapy or in combination with other drugs or therapeutic applications.

32 Background: Patients retreated with rituximab often relapse which limit patient treatment options (Goldman/Cairo, Leukemia, 2013). Our group has successfully expanded functional and active peripheral blood NK cells (exPBNK) to target BL (Chu/Cairo, et al, Can Imm Res, 2015). 2B8T2M was generated by fusing ALT-803, an IL-15 superagonist, to four single-chains of rituximab (Liu/Wong, et al, JBC, 2016). 2B8T2M displayed tri-specific CD20 binding activity, activated NK cells to enhance antibody-dependent cellular cytotoxicity, and induced apoptosis of B-lymphoma cells (Liu/Wong, et al, JBC, 2016). Methods: ALT-803 and 2B8T2M were generously provided by Altor BioScience Corporation. NK expansion, NK receptors expression and cytotoxicity were examined as we previous described (Chu/Cairo, et al, Can Imm Res 2015). IFNg and granzyme B levels were examined by ELISA assays. Equal doses of IgG, Rituximab, ALT-803, Rituximab+ALT-803, obinutuzumab (obinu, generously provided by Christian Klein, PhD from Roche) were used for comparison. Results: 2B8T2M significantly enhanced exPBNK cytotoxicity against rituximab-sensitive Raji cells compared to the controls IgG, Rituximab, ALT-803, Rituximab+ALT-803, obinu (p < 0.001, E:T = 1:1). 2B8T2M also significantly enhanced exPBNK cytotoxicity against rituximab-resistant Raji-2R cells (p < 0.001, E:T = 1:1) and resistant Raji-4RH cells (p < 0.001, E:T = 1:1). Furthermore, 2B8T2M significantly enhanced IFN-g and granzyme B production from exPBNK against Raji, Raji-2R and Raji-4RH compared to IgG (p < 0.001), rituximab (p < 0.001), ALT-803 (p < 0.001), Rituximab+ALT-803 (p < 0.001), and obinutuzumab (p < 0.001). Conclusions: 2B8T2M compared to rituximab, ALT-803 or obinutuzumab significantly enhanced exPBNK in vitro cytotoxicity against rituximab-sensitive and –resistant BL cells. The in vivo functions of 2B8T2M with exPBNK using humanized NSG models are under investigation.

Swietenia Macrophylla

BACKGROUND: Insulin resistance (IR) is known as the root cause of type 2 diabetes; hence, it is a substantial therapeutic target. Nowadays, studies have shifted the focus to natural ingredients that have been utilized as a traditional diabetes treatment, including Swietenia macrophylla. Accumulating evidence supports the hypoglycemic activities of S. macrophylla seeds extract, although its molecular mechanisms have yet to be well-established. AIM: This review focuses on the hypoglycemic molecular mechanisms of S. macrophylla seeds extract and its safety profiles. METHODS: An extensive search of the latest literature was conducted from four main databases (PubMed, Scopus, Science Direct, and Google Scholar) using several keywords: “swietenia macrophylla, seeds, and diabetes;” “swietenia macrophylla, seeds, and oxidative stress;” “swietenia macrophylla, seeds, and inflammation;” “swietenia macrophylla, seeds, and GLUT4;” and “swietenia macrophylla, seeds, and toxicities.” RESULTS: The hypoglycemic activities occur through modulating several pathways associated with IR and T2D pathogenesis. The seeds extract of S. macrophylla modulates oxidative stress by decreasing malondialdehyde (MDA), oxidized low-density lipoprotein, and thiobarbituric acid-reactive substances while increasing antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase). Another propose mechanism is the modulating of the inflammatory pathway by attenuating nuclear factor kappa β, tumor necrosis factor α, inducible nitric oxide synthase, and cyclooxygenase 2. Some studies have shown that the extract can also control phosphatidylinositol-3-kinase/ Akt (PI3K/Akt) pathway by inducing glucose transporter 4, while suppressing phosphoenolpyruvate carboxykinase. Moreover, in vitro cytotoxicity and in vivo toxicity studies supported the safety profile of S. macrophylla seeds extract with the LD50 higher than 2000 mg/kg. CONCLUSION: The potential of S. macrophylla seeds as antidiabetic candidate is supported by many studies that have documented their non-toxic and hypoglycemic effects, which involve several molecular pathways.
