Promises of phytochemical based nano drug delivery systems in the management of cancer.

Cancer is the leading cause of human disease and death worldwide, accounting for 7.6 million deaths per year and projected to reach 13.1 million by 2030.

A review on epidermal growth factor receptor's role in breast and non-small cell lung cancer.

Epithelial growth factor receptor (EGFR) is a cell surface transmembrane receptor that mediates the tyrosine signaling pathway to carry the extracellular messages inside the cell and thereby alter the function of nucleus. This leads to the generation of various protein products to up or downregulate the cellular function. It is encoded by cell erythroblastosis virus oncogene B1, so called C-erb B1/ERBB2/HER-2 gene that acts as a proto-oncogene.

Nuclear factor-kappa B and its role in inflammatory lung disease.

Nuclear factor-kappa B, involved in inflammation, host immune response, cell adhesion, growth signals, cell proliferation, cell differentiation, and apoptosis defense, is a dimeric transcription factor. Inflammation is a key component of many common respiratory disorders, including asthma, chronic obstructive pulmonary disease (COPD), bronchiectasis, and acute respiratory distress syndrome. Many basic transcription factors are found in NF-κB signaling, which is a member of the Rel protein family.

Virological surveillance, molecular phylogeny, and evolutionary dynamics of hepatitis C virus subtypes 1a and 4a isolates in patients from Saudi Arabia.

Hepatitis C virus (HCV) subtypes are pre-requisite to predict endemicity, epidemiology, clinical pathogenesis, diagnosis, and treatment of chronic hepatitis C infection. HCV genotypes 4 and 1 are the most prevalent in Saudi Arabia, however; less consensus data exist on circulating HCV subtypes in infected individuals. This study was aimed to demonstrate the virological surveillance, phylogenetic analysis, and evolutionary relationship of HCV genotypes 4 and 1 subtypes in the Saudi population with the rest of the world.

Consensus small interfering RNA targeted to stem-loops II and III of IRES structure of 5' UTR effectively inhibits virus replication and translation of HCV sub-genotype 4a isolates from Saudi Arabia.

Being the most conserved region of all hepatitis C virus (HCV) genotypes and sub-genotypes, the 5' untranslated region (5' UTR) of HCV genome signifies it's importance as a potential target for anti-mRNA based treatment strategies like RNA interference. The advent and approval of first small interference RNA (siRNA) -based treatment of hereditary transthyretin-mediated amyloidosis for clinical use has raised the hopes to test this approach against highly susceptible viruses like HCV. We investigated the antiviral potential of consensus siRNAs targeted to stem-loops (SLs) II and III nucleotide motifs of internal ribosome entry site (IRES) structure within 5' UTR of HCV sub-genotype 4a isolates from the Saudi population.

Cardioprotective effect of 6-shogaol against hyperglycemia-induced toxicity in H9c2 cardiomyocytes via suppressing of NF-κB pathway.

Diabetic cardiomyopathy (DC) is a serious complication of diabetes. Apoptosis, inflammatory and ROS production are among the factors that are involved in the progression of diabetic cardiomyopathy. 6-shogaol is reported to inhibit apoptosis and reduce inflammatory and ROS production.

6-shogaol protects against diabetic nephropathy and cardiomyopathy via modulation of oxidative stress/NF-κB pathway.

Diabetes dramatically increases the risk of numerous heart and kidney troubles. Diabetic nephropathy (DN) and cardiomyopathy (DC) are major causes of death. The pathophysiology of DN/DC includes inflammatory and oxidative stress mechanisms.

In vitro inhibitory analysis of consensus siRNAs against NS3 gene of hepatitis C virus 1a genotype.

Objective: To explore inhibitory effects of genome-specific, chemically synthesized siRNAs (small interference RNA) against NS3 gene of hepatitis C virus (HCV) 1a genotype in stable Huh-7 (human hepatoma) cells as well as against viral replication in serum-inoculated Huh-7 cells.

Methods: Stable Huh-7 cells persistently expressing NS3 gene were produced under antibiotic gentamycin (G418) selection. The cell clones resistant to 1000 μg antibiotic concentration (G418) were picked as stable cell clones.

Real-world challenges for hepatitis C virus medications: a critical overview.

From 2010, the landscape of hepatitis C therapeutics has been changed rapidly, and today we are standing at a cusp of a pharmacological revolution where highly effective and interferon (IFN)-free direct acting antivirals (DAAs) are already on the market. Such treatment paradigms attain 90-95% sustained virologic response (SVR; undetectable viral load at week 12 or 24 at the end of therapy) rates in treated individuals compared to 50-70% with treatment completion of dual-therapy-pegylated interferon (PEG-IFN) and ribavirin (RBV). As the major goal now for the hepatologists, clinicians, physicians, and health care workers is likely to eradicate hepatitis C infection in parallel to treatment, the demand is for a one-size-fits-all pill that could be prescribed beyond the limitations of hepatitis C genotype, viral load, previous treatment history, advanced hepatic manifestations (fibrosis, cirrhosis) and antiviral drug resistance.

Assessment methods for angiogenesis and current approaches for its quantification.

Angiogenesis is a physiological process which describes the development of new blood vessels from the existing vessels. It is a common and the most important process in the formation and development of blood vessels, so it is supportive in the healing of wounds and granulation of tissues. The different assays for the evaluation of angiogenesis have been described with distinct advantages and some limitations.
