OBJECTIVE(S) Regarding the presence of many active biological constituents in Avicennia marina, the present investigation was carried out to study cytotoxic activity of crude methanol leave extract and column chromatographic fractions of A. marina against MDA-MB 231 cell line (human breast cancer cell) and HEK (Human embryonic kidney cell) line. MATERIALS AND METHODS The anticancer activity o...

shiga toxins (stxs) are bacterial virulence factors produced by shigella dysenteriae serotype 1 and escherichia coli strains. stxs are critical factors for the development of diseases such as severe bloody diarrhea and hemolytic uremic syndrome. additionally, stxs trigger the secretion of pro- inflammatory cytokines and chemokines, particularly in monocytes or macrophages. the inflammatory cyto...

UBIAD1 plays critical roles in physiology including vitamin K and CoQ10 biosynthesis as well as pathophysiology including dyslipimedia-induced SCD (Schnyder's corneal dystrophy), Parkinson's disease, cardiovascular disease and bladder carcinoma. Since the subcellular localization of UBIAD1 varies in different cell types, characterization of the exact subcellular localization of UBIAD1 in specif...

Abstract Nickel oxide (NiO) nanoparticles are gaining popularity in multiple fields owing to their useful properties. The application biomedicine has been further enhanced by combining them with plant extracts that possess unique biological In this report, NiO were synthesized mediating the reaction process leaf of Kei-apple ( Dovyallis Caffra ), a local fruit tree found South Africa. Various c...

Studies on the adenovirus type 2-simian virus 40 (SV40) hybrid population demonstrated two genetically stable variants within this population, which were isolated by plaquing in African green monkey kidney cells. These variants were similar in that each induced SV40 T antigen in human embryonic kidney cells and contained similar concentrations of nonhybrid adenovirus type 2 virions and adenovir...

The possibility to reprogram somatic human cells will greatly and deeply change genetic approach and allow the development of new tools to study genetics diseases. Indeed, our ability to study human genetic diseases suffers from the lack of valid in vitro models. The latter should (i) be originating from human primary cells, (ii) be able to self-renew for a long time and (iii) be able to differ...

DiGeorge Syndrome (DGS) Critical Region 8 (DGCR8) is a primary candidate gene in they DGS. The DGCR8 microprocessor complex subunit an essential cofactor the canonical miRNA biogenesis which involved diverse cellular functions such as cell fate decisions, apoptosis and different signaling pathways. However, role of these processes or development DGS not fully understood. Here we present heteroz...
