Traditional Turkish coffee (TTC) is highly associated with caffeine and is known as a mind and heart stimulant as it helps keep tiredness at bay. Daily consumption of TTC naturally benefits human health such as anti-cancer, anti-diabetic, improved energy, anti-depression, reduced risk of heart disease, etc. The TTC was derived from particular types of Arabic coffee beans (ACB), and the preparation method of TTC is unique from other types of coffee. The main objective of the study was to investigate the therapeutic and biological effects of TTC. The ACB powder was characterized physicochemically using UV-Vis spectroscopy, Fourier transforms infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). In vitro analysis using HaCaT (Human keratinocyte cell line) proved the biocompatibility of ACB powder. Case studies which were focusing on healthy individuals as the research populace were conducted using TTC. Consumption of TTC was found beneficially compared to other types of coffee. The TTC was obtained from ACB, which was characterized by spectroscopic techniques and displayed biocompatibility due to the results on HaCaT cell lines. The TTC has beneficial therapeutic effects on individuals. According to statistical analysis, the disease-affected ratio of diabetes, heart disease, and depression was significantly decreased.

Lipid fractions of gonads present in sea urchins serves as a source of bioactive agents with potent pharmaceutical properties. The present study reports the in-vitro biological effects of lipids isolated from gonads of sea urchin: Stomopneustes variolaris collected from the East coast of India. The extracted lipids were characterized by spectroscopic techniques such as GCMS and FTIR and tested for in-vitro biological effects. GCMS analysis of the lipid extract detected high levels of hexa triacontane (17.023 %), tetratetracontane (15.913%), and octacosane (15.628%) and low concentrations of oleic acid (2.206%) and sulfurous acid, pentadecy 2-propyl ester (1.744%). FTIR analysis identified rich composition of functional groups present in the lipids such as 3418.93 cm-1 (hydroxyl), 2921.08cm-1 and 2854.81 cm-1 (alkane), 2660.69 cm-1 (carboxylic acid), 1596.11 cm-1 (amine), 1291.76 cm-1 (aromatic amine). The lipid fraction evaluated by agar diffusion assay measured in terms of zone of inhibition showed bactericidal effects against gram-positive bacteria: Streptococcus aureus (30 mm); Pseudomonas aeruginosa (28.5 mm) and gram-negative bacteria: Escherichia coli (29.5 mm); Klebsiella pneumonia (27.5 mm) and Vibrio cholera (28 mm) respectively. The lipid fraction also showed an effective anti-fungal effect against C.albicans (25 mm). Further, the lipid fractions showed good radical scavenging effect against total phenolic, flavonoid content (15.12 mg GAE/g and 32.72 mg QE/g), and hydrogen peroxide radicals (IC50- 48.28mg/ml) confirming its anti-oxidant potential. Based on the observed results, it was identified that the lipid fraction of gonads of Stomopneustes variolaris demonstrated various biological effects such as bactericidal, anti-fungal and radical scavenging activities which could have a great scope in the formulation of biopharmaceutical agents.

Abstract Background: Radiation-induced heart disease have been reported, but the mechanisms remain unclear. Mesenchymal stem cells (MSCs), also resident in heart are highly susceptible to radiation. We examined the hypothesis that altered secretion of exosomes from MSCs as the triggers of radiation-induced heart disease. Methods: By exposing human placental tissue-derived MSCs to 5 Gy γ-rays, we will then isolate exosomes from the culture medium 48h later and use to evaluate the quantity and quality changes of exosomes from MSCs after radiation exposures. The biological effects of exosomes from irradiated MSCs on HUVEC and H9c2 cells were also examined. Results: Although the amount and size distribution of exosomes did not differ between the non-irradiated and irradiated MSCs, miRNA sequences indicated many up- or down-regulated miRNAs in irradiated MSCs-exosomes. In vitro experiments using HUVEC and H9c2 cells showed that irradiated MSCs-exosomes significantly decreased cell proliferation, but increased cell apoptosis and DNA damage. Moreover, irradiated MSCs-exosomes impaired the tube formation of HUVEC cells and induced calcium overload of H9c2 cells. Conclusions: Exosomes released from irradiated MSCs shows an altered miRNA profiling and harmful effect to damage heart cells, which provides new insight on the mechanism of radiation-related heart disease risks.

Sesame (Sesamum indicum L.) seeds have been authenticated for its medicinal value in both Chinese and Indian systems of medicine. Its numerous potential nutritional benefits are attributed to its main bioactive constituents, sesamol. As a result of those studies, several molecular mechanisms are emerging describing the pleiotropic biological effects of sesamol. This review summarized the most interesting in vitro and in vivo studies on the biological effects of sesamol. The present work summarises data available from Pubmed and Scopus database. Several molecular mechanisms have been elucidated describing the pleiotropic biological effects of sesamol. Its major therapeutic effects have been elicited in managing oxidative and inflammatory conditions, metabolic syndrome and mood disorders. Further, compelling evidence reflected the ability of sesamol in inhibiting proliferation of the inflammatory cell, prevention of invasion and angiogenesis via affecting multiple molecular targets and downstream mechanisms. Sesamol is a safe, non‐toxic chemical that mediates anti‐inflammatory effects by down‐regulating the transcription of inflammatory markers such as cytokines, redox status, protein kinases, and enzymes that promote inflammation. In addition, sesamol also induces apoptosis in cancer cells via mitochondrial and receptor‐mediated pathways, as well as activation of caspase cascades. In the present review, several pharmacological effects of sesamol are summarised namely, antioxidant, anti-cancer, neuroprotective, cardioprotective, anti-inflammatory, hypolipidemic, radioprotective, anti-aging, anti-ulcer, anti-dementia, anti-depressant, antiplatelet, anticonvulsant, anti-anxiolytic, wound healing, cosmetic (skin whitening), anti-microbial, matrix metalloproteinase (MMPs) inhibition, hepatoprotective activity and other biological effects. Here we have summarized the proposed mechanism behind these pharmacological effects.

Mesenchymal stem cell (MSC) derived extracellular vesicles (EV) are emerging as acellular therapeutics for solid organ injury and as carriers for drug delivery. Graphene-based materials are novel two-dimensional crystal structure-based materials with unique characteristics of stiffness, strength and elasticity that are being explored for various structural and biological applications. We fabricated a biomaterial that would capture desirable properties of both graphene and stem cell derived EV. Metabolically engineered EV that express azide groups were cross-linked with alkyne-functionalized graphene oxide (GO) via a copper catalyzed alkyne-azide cycloaddition (CuAAC) reaction. The crosslinking between EV and GO was accomplished without the need for ligand expression on the metal. Scanning electron and fluorescence microscopy demonstrated excellent cross-linking between EV and GO. Biological effects were assessed by phagocytosis studies and cell viability studies. The uptake of GO or sonicated GO (sGO) resulted in a durable pro-inflammatory immune response. Cell studies further showed that crosslinked GO-EV scaffolds exhibited cell-type dependent cytotoxicity on liver cancer cells whereas there was minimal impact on healthy hepatocyte proliferation. In vitro, neither GO-EV nor sGO-EV induced DNA strand breaks. In vivo studies in zebrafish revealed gross developmental malformations but treatment-induced mortality was only seen with the highest doses of GO-EV and sGO-EV. With these advantages, this engineered biomaterial combining the versatility of graphene with the therapeutic effects of MSC-EV has potential for applications in tissue engineering and regenerative medicine.

Antidiabetic Effects

Type-2 diabetes mellitus (T2DM) and therapy options have been studied increasingly due to their rising incidence and prevalence. The trend of applying traditional Chinese medicine (TCM) to treat T2DM is increasing as a crucial medical care for metabolic dysfunctions. Gegen Qinlian decoction (GQL), a well-known classical TCM formula used in China, has been clinically applied to treat various types of chronic metabolic diseases. However, antidiabetic effects of GQL administration during T2DM have never been studied systematically. We assessed physiological and molecular targets associated with therapeutic effects of GQL by evaluating network topological characteristics. The GQL-related biological pathways are closely associated with antidiabetic effects, including the TNF and PI3K–AKT signaling pathways. Associated primary biological processes such as RNA polymerase II promoter transcription participate in the inflammatory response, oxidative stress reduction, and glucose metabolic process, thereby exerting multiple biological effects on the antidiabetic mechanism. Furthermore, our results showed that GQL can affect blood glycemic levels and ameliorate inflammatory symptoms, and liver and pancreas tissue injury in high-fat diet plus streptozotocin-induced diabetic mice. In vivo and in vitro experiments confirmed that antidiabetic effects of GQL were associated with a modulation of the TNF and PI3K–AKT–MTOR pathways.

Glucocorticoids (GC ) have been an integral component of the treatment of leukemias and lymphomas for several decades. Specific cytotoxic effect of GC on transformed lymphoblasts mediates their use at the stage of the remission induction as well as consolidation of treatment. However, the main problem of the long-term GC use is the development of atrophic and metabolic side effects as well as GC resistance. The biological effects of GC are realized via activation of the glucocorticoid receptor (GR) by two mechanisms: transrepression (TR) associated with the therapeutic effects of GC , and transactivation (TA ), which mediates the development of metabolic and atrophic complications. It was demonstrated that an increase in the expression of the GC - dependent gene REDD1 associated with GC -induced skin, muscle and bone atrophy of the skin, muscle and bone tissue was realized via the induction of transactivation. Therefore, identification of potential inhibitors of REDD1 expression and study of their biological effects in combination with GC in models of leukemia and lymphoma is of particular interest. In our recent study we have selected a number of drugs from the class of PI 3K/Akt/mTO R modulators using bioinformatic screening. These drugs effectively inhibited REDD1 expression, modulated GR activity and shifted it towards transrepression, and prevented the development of GC -induced side effects in mice. Here we aimed to study the effects of potential inhibitors of REDD1 expression from different pharmacological groups, the compounds Emetine and CGP -60474, on leukemia and lymphoma cells in combination with GC . We demonstrated antitumor effect of the compounds in vitro, a decrease in the expression of TA -associated genes and an increase in TR induction. Further studies of the antitumor effects of REDD1 expression inhibitors (Emetine and CGP -60474 is a promising area of research.

Abstract Biotin, a water-soluble B complex vitamin, is possibly involved in chronic inflammatory diseases, although the detailed mechanisms are unclear. In this study, we investigated the effects of biotin status on nickel (Ni) allergy in mice. Mice were fed a basal or biotin-deficient (BD) diet for 8 wk and sensitized with an intraperitoneal injection of NiCl2 and lipopolysaccharide. Ten days after sensitization, NiCl2 was intradermally injected into pinnas and ear swelling was measured. For in vitro analysis, we cultured a murine macrophage cell line, J774.1, under a biotin-sufficient (C, meaning control) or BD condition for 4 wk and analyzed interleukin (IL)-1 production. Significantly higher ear swelling was induced in BD mice than C mice. Adaptive transfer of splenocytes from both C and BD mice induced Ni allergy in unsensitized mice. Regardless of donor mice, ear swelling was significantly higher in BD recipient mice than C recipient mice. Ni allergy was not induced in either C or BD IL-1−/− mice. Splenocytes from BD mice produced a significantly higher amount of IL-1β than those from C mice. Production and mRNA expression of IL-1β were significantly higher in BD J774.1 cells than in C cells. Biotin supplementation inhibited the augmentation of IL-1β production in vitro. In vivo supplementation of biotin in drinking water dose-dependently decreased ear swelling in C and BD mice. These results indicate that biotin status affects Ni allergy in the elicitation phase via the upregulation of IL-1β production in mice, suggesting that biotin supplementation may have therapeutic effects on human metal allergy.

Mapk Signaling Pathways

Hepatocellular carcinoma (HCC) is the fifth most common malignant tumor and the second leading cause of cancer-related death in the world. Plumbagin (PL) is a small molecule naphthoquinone compound isolated from Plumbago zeylanica L. that has important anticancer properties, but its mechanism requires further investigation. In this study, we used a comprehensive network pharmacology approach to study the mechanism of action of PL for the treatment of HCC. The method includes the construction of multiple networks; moreover, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to identify biological processes and signaling pathways. Subsequently, in vitro experiments were performed to verify the predicted molecular mechanisms obtained from the network pharmacology-based analysis. Network pharmacological analysis showed that PL may exert anti-HCC effects by enhancing reactive oxygen species (ROS) production to generate oxidative stress and by regulating the PI3K/Akt and MAPK signaling pathways. In vitro experiments confirmed that PL mainly mediates the production of ROS, regulates the PI3K/Akt and MAPK signaling pathways to promote apoptosis and autophagy, and shows significant therapeutic effects on HCC. In conclusion, our work proposes a comprehensive systems pharmacology approach to explore the potential mechanism of PL for the treatment of HCC.
