Abstract Cancer frequently develops resistance to the majority of chemotherapy treatments. This study aimed to examine the synergistic cytotoxic and antitumor effects of SGLT2 inhibitors, specifically Canagliflozin (CAN), Dapagliflozin (DAP), Empagliflozin (EMP), and Doxorubicin (DOX), using in vitro experimentation. The precise combination of CAN+DOX has been found to greatly enhance the cytotoxic effects of doxorubicin (DOX) in MCF-7 cells. Interestingly, it was shown that cancer cells exhibit an increased demand for glucose and ATP in order to support their growth. Notably, when these medications were combined with DOX, there was a considerable inhibition of glucose consumption, as well as reductions in… More > Graphic Abstract

Abstract Biocompatible graphene derivative materials (GBMs) to harness the maximum potential of pristine graphene biologically, is the most important strategy for its advanced applications in pharmaceutical and other biomedical fields. Currently, scientists are trying to find this by using biopolymer nanocomposites or anchored materials. Nevertheless, tuning the bare GBMs towards biocompatibility is a beautiful approach to exploit the fundamental potential of pristine graphene vis-à-vis suppressing the effects of incorporated biopolymers or anchored materials. Herein, a large-scale, cost-effective, facile, and environment-friendly green synthetic strategy is used for the synthesis of reduced graphene oxide (rGO) nanosheet using L-ascorbic acid (L-AA) as a reducing/stabilizing/capping… More >

Abstract 5-Fluorouracil (5-FU) is a commonly used chemotherapeutic agent for various cancers. However, the drug resistance developed by tumor cells hinders the therapeutic effect. Konjac glucomannan (KGM) is indicated to sensitize 5-FU-resistant hepatocellular carcinoma (HCC) cells to 5-FU. In our study, we found that KGM or 5-FU treatment alone did not affect the malignant cell behaviors and endoplasmic reticulum (ER) stress of 5-FU-resistant HCC cells or HepG2/5-FU and Bel-7402/5-FU cells, while cotreatment with KGM and 5-FU significantly facilitated HCC cell apoptosis and ER stress and suppressed cell proliferation potential and migration abilities. Moreover, we explored the underlying mechanism by which KGM… More >

Abstract Glioma is a commonly diagnosed brain tumor that shows high mortality rate. Despite the great advancement of cancer therapy in recent years, chemotherapy is still an important approach for treatment of glioma. However, long-term chemotherapy usually causes serious side effects or complications. It is desirable to take strategies to enhance the efficacy of current chemotherapy. In the present study, we observed obvious upregulation of miR-374a in glioma cells. More importantly, we found that knockdown of miR-374a was able to enhance the etoposide-induced cytotoxicity against glioma cells. Mechanically, we demonstrated that FOXO1 was the target of miR-374a in glioma. Treatment with… More >

Abstract

Microbial infections cause complicated health influences along with bad economic impacts. In the present investigation, three dominant seaweeds namely, Amphiroa anceps, Corallina officinalis and Sargassum filipendula were collected from different Egyptian sites at the Red Sea and Mediterranean Sea during autumn 2019. Organic extracts of the three algae were screened for their antibacterial activity against three pathogenic bacteria Salmonella typhiimurium, Staphylococcus aureus and Escherichia coli, in addition to in vitro antiviral activity against Rotavirus (RV), and Coxsackie virus B3 (CVB3) that cause severe diseases in human. Organic extract of A. anceps, C. officinalis and S. filipendula inhibit E. coli cells… More >

Abstract The medicinal plant of Acer tegmentosum Maxim is traditionally used in the southern part of Asia to treat oxidative stress-related diseases, including cancer, diabetes mellitus , wounds, infections, etc. Based on this, the current study was designed to investigate the phytochemical analysis, antioxidants and anti-cancer activities of Acer tegmentosum Maxim (AT). The total phenolic content (TPC), total flavonoid content (TFC), free radicals scavenging (DPPH and ABTS), chemical constituents as well as cytotoxicity potential ATWE (Acer tegmentosum Maxim water extracts) and ATEE (Acer tegmentosum Maxim ethanolic extracts) were tested. The cytotoxic efficacy ATWE and ATEE were studied in Human embryonic kidney… More >

Abstract A protective action of melatonin (MELAT) on docetaxel (DCT)-induced inflammation, apoptosis, and reactive free oxygen radical (fROS) generation values via blocking of TRPM2 calcium-permeable channel was investigated in different cells except for laryngo-tracheal epithelial (LT-Epi) cells. Hence, the protective action of MELAT on DCT-induced oxidative toxicity and inflammation in LT-Epi tissue and cells of mice were investigated in the current study. MELAT treatment ameliorated DCTinduced mitochondrial ROS in the LT-Epi cells by reducing the generation of fROS (cytosolic and mitochondrial), lipid peroxidation, and depolarization of the mitochondrial membrane, while increasing reduced glutathione (GSH), GSH peroxidase, and total antioxidant status. In… More >

Abstract The flower of Butea monosperma (Lam.) (Fabaceae) has been used in traditional Indian medicine in the treatment of many ailments including liver disorders. To understand the pharmacological basis of its beneficial effects, the extracts of dried flowers in water, methanol, butanol, ethyl acetate and acetone were evaluated for free radical scavenging and pro-apoptotic activities in cell cultures (human hepatoma Huh-7 cell line and immortalized AML-12 mouse hepatocytes). Butrin and butein -the active constituents of flower extracts- were used as reference molecules. The levels of cell injury markers like lactate dehydrogenase, glutathione and lipid peroxidation and primary antioxidant enzymes glutathione S-transferase… More >

Abstract Cell-based biosensors have become a research hotspot in the biosensors and bioelectronics fields. The main feature of cell-based biosensors is immobilization of living cells on the surface of transducers. Different types of polymers which are used as scaffolds for cell growth should be biocompatible and should have reactive functional groups for further attachment of biomolecules. In this work, cell attachment and proliferation on chitosan hydrogel, chitosan-gelatin and gold nanoparticle-chitosan nanocomposite membranes was studied. Characterization of the membranes was performed using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Cytotoxicity assessment on HEK293 cells was carried out for all… More >

Abstract Current investigation has shown that human exposure to aflatoxins is not limited to the administration of contaminated cereals, but water is another possible source. This study was aimed to design easily applicable method to eliminate aflatoxin B2 (AFB2) from contaminated drinking water. Electrospinning has been used for preparation of probiotic-coated polyvinyl alcohol (PVA) and cellulose acetate (CA) nanofibers. Both of these hybrid nanofibers were studied by scanning electron microscopy (SEM) and Fourier-transformed infrared spectroscopy (FT-IR). SEM showed the proper coating of probiotic strains (Kluyveromyces lactis CBS 2359 and Saccharomyces cerevisiae ATCC 9763) on both nanofiber types. Different areas (1-5 cm²)… More >
