The effect of Nrf deletion on the proteomic signature in a human colorectal cancer cell line.

Background: Colorectal cancer is one of the most common cancer and the third leading cause of death worldwide. Increased generation of reactive oxygen species (ROS) is observed in many types of cancer cells. Several studies have reported that an increase in ROS production could affect the expression of proteins involved in ROS-scavenging, detoxification and drug resistance.

Autophagy stimulation delayed biological aging and decreased cardiac differentiation in rabbit mesenchymal stem cells.

Cardiovascular disease (CVD) is a type of disease that affects the function of cardiac-vascular tissues. This study aimed to consider the possible effects of autophagy, as an intrinsic catabolic pathway of cells, on the differentiation and aging process of mesenchymal stem cells (MSCs). In this study, bone marrow-derived MSCs were obtained from rabbit bone marrow aspirates.

Current status of cardiac regenerative medicine; An update on point of view to cell therapy application.

Cardiovascular diseases (CVDs) are the leading cause of death globally. Because of the economic and social burden of acute myocardial infarction and its chronic consequences in surviving patients, understanding the pathophysiology of myocardial infarction injury is a major priority for cardiovascular research. MI is defined as cardiomyocytes death caused by an ischemic that resulted from the apoptosis, necrosis, necroptosis, and autophagy.

Pathophysiological Effects of Sulfur Mustard on Skin and its Current Treatments: Possible Application of Phytochemicals.

Background: Sulfur-(SM) and nitrogen (NM)-based mustards are the mutagenic incapacitating compounds which are widely used in vesicating the chemical warfare and cause toxicity in many organs, especially skin. SM, as a potent vesicating agent, contributes to the destruction of skin in dermis and epidermis layers. The progression of the lesion depends on the concentration of SM and the duration of exposure.

The relationship between ANT1 and NFL with autophagy and mitophagy markers in patients with multiple sclerosis.

Multiple sclerosis (MS) is the most common inflammatory neurodegenerative disease. Neurofilament light chain (NFL) is a novel adverting biomarker of axonal damage that suggested as a useful assistant in the monitoring of MS patients. It has been shown that the auto/mitophagy associated with MS pathogenesis.

Distinct Effects of Royal Jelly on Human Endothelial Cells Under High Glucose Condition.

To assess different effects of royal Jelly in protecting the human endothelial cells from high glucose level, human umbilical vein endothelial cells were exposed to various concentrations of royal jelly, from 0.625 to 10 mg/mL, at the presence of 5 and 30 mM glucose contents over a course of 72 h. In addition to cell viability assessment by conventional MTT assay, we also analyzed the feature of stemness by expression of Sox-2 and CD133 factors.

Chronic Exposure of Human Endothelial Progenitor Cells to Diabetic Condition Abolished the Regulated Kinetics Activity of Exosomes.

By virtue of lifestyle change, incidence of diabetes mellitus type 2 is increasingly being raised with different up-surging pathologies. It was showed that endothelial progenitor cells (EPCs) were disqualified in neo-angiogenesis induction. Besides, to an aborted differentiation property, malfunctioned paracrine activities worsen off vascular abnormality.

Telomerase activity and telomere on stem progeny senescence.

The end of linear chromosomes is formed of a special nucleoprotein heterochromatin structure with repetitive TTAGGG sequences called telomere. Telomere length is regulated by a special enzyme called telomerase, a specific DNA polymerase that adds new telomeric sequences to the chromosome ends. Telomerase consists of two parts; the central protein part and the accessory part which is a RNA component transported by the central part.

Copper sulfate pentahydrate reduced epithelial cytotoxicity induced by lipopolysaccharide from enterogenic bacteria.

The over usage of multiple antibiotics contributes to the emergence of a whole range of antibiotic-resistant strains of bacteria causing enterogenic infections in poultry science. Therefore, finding an appropriate alternative natural substance carrying an antibacterial capacity would be immensely beneficial. It has been previously discovered that the different types of cupric salts, especially copper sulfate pentahydrate (CuSO·5HO), to carry a potent bactericidal capacity.

Endothelial cells' biophysical, biochemical, and chromosomal aberrancies in high-glucose condition within the diabetic range.

To date, many studies have been conducted to find out the underlying mechanisms of hyperglycemia-induced complications in diabetes mellitus, attributed to the cellular pathologies of different cells-especially endothelial cells. However, there are still many ambiguities and unresolved issues to be clarified. Here, we investigated the alteration in biophysical and biochemical properties in human umbilical vein endothelial cells exposed to a high-glucose concentration (30mM), comparable to glucose content in type 2 diabetes mellitus, over a course of 120 hours.

Type 2 Diabetes Inhibited Human Mesenchymal Stem Cells Angiogenic Response by Over-Activity of the Autophagic Pathway.

The current study aimed to address the impact of serum from type 2 diabetes patients on the angiogenic properties of human bone marrow mesenchymal stem cells and its relationship to autophagy signaling. Human primary stem cells were enriched and incubated with serum from diabetic and normal subjects for 7 days. Compared to data from the control group, diabetic serum was found to induce a higher cellular death rate (P < 0.

A reversal of age-dependent proliferative capacity of endothelial progenitor cells from different species origin in in vitro condition.

A large number of cardiovascular disorders and abnormalities, notably accelerated vascular deficiencies could be related to aging changes and increased length of life. During the past decades, the discovery of different stem cells facilitates ongoing attempts for attenuating many disorders, especially in vascular beds. Endothelial progenitor cells (EPCs) are a subtype of stem cells that have potent capacity to differentiate into mature endothelial cells (ECs).

Taq1B Polymorphism of Cholesteryl Ester Transfer Protein (CETP) and Its Effects on the Serum Lipid Levels in Metabolic Syndrome Patients.

The metabolic syndrome (MetS) is one of the most important risk factors for type 2 diabetes and cardiovascular disease. This syndrome is characterized by abdominal obesity, hypertension, insulin resistance, and dyslipidemia. The plasma origin of Cholesteryl ester transfer protein (CETP) is responsible for transferring cholesterol esters from high-density lipoprotein particles to apolipoprotein B containing lipoproteins compartment.

Effects of combination of melatonin and laser irradiation on ovarian cancer cells and endothelial lineage viability.

The main goal of anti-cancer therapeutic approaches is to induce apoptosis in tumor masses but not in the normal tissues. Nevertheless, the combination of photodynamic irradiation with complementary oncostatic agents contributes to better therapeutic performance. Here, we applied two different cell lines; SKOV3 ovarian carcinoma cells and HUVECs umbilical cord cells as in vitro models to pinpoint whether pharmacological concentration of melatonin in combination with photodynamic therapy induces cell cytotoxicity.

Potent anti-angiogenic and cytotoxic effect of conferone on human colorectal adenocarcinoma HT-29 cells.

Background: Cancer is one of the leading causes of death worldwide, both in developed and developing countries. Of note, colorectal adenoma encompasses a high rate of gastrointestinal-associated cancer death in human being. Today, different strategies, including surgery approaches, photodynamic therapy, radiation and particularly natural compounds have been extensively used to manage tumor behavior in human body.
