Lytic polysaccharide monooxygenases (LPMOs) are relatively new enzymes that have been discovered 10 years ago. LPMOs comprise a diverse group of enzymes which play a pivotal role in the depolymerization of sugar-based biopolymers including cellulose, hemicellulose, chitin, and starch. Their mechanism of action relies on the correct coordination of...

Background: Selenium is a mineral that showed both pro- and anti-oxidant activities in various disease models. In this study, we evaluated the anti-tumor effect of selenium against 1,2-dimethylhydrazine (DMH)-induced colorectal cancer in BALB/C mice and its effect on apoptosis and angiogenesis. Methods: Colorectal cancer was induced by subcutane...

Hepatocellular carcinoma (HCC) is the second leading cause of cancer‐related death worldwide. Oxidative stress contributes significantly to HCC pathogenesis. In this study, we investigated the possible chemoprotective effect of the thiol group‐containing compound, tiopronin, against HCC induced chemically by diethylnitrosamine (DENA) in rats. In ad...
Article
Background: HOX transcript antisense RNA (HOTAIR) and H19 are two long noncoding RNAs that play vital functions in the development of colorectal cancer (CRC). Subjects and Methods: The expression level of HOTAIR and H19 in the sera samples of Egyptian CRC patients along with normal controls was evaluated by quantitative real-time PCR. The possible...
Article
Hesperidin is a flavanone glycoside that is found in the Citrus species and showed antioxidant, hepatoprotective as well as anticancer activity. This study investigated the effect of hesperidin on the PI3K/Akt pathway as a possible mechanism for its protective effect against diethylnitrosamine (DEN)‐induced hepatocellular carcinoma (HCC). Adult Wis...

Colon cancer is a complex disease that involves numerous genetic alterations that change the normal colonic mucosa into invasive adenocarcinoma. In the current study, the protective effects of inulin (prebiotic), Lactobacillus casei (L. casei, probiotic) and their combination (synbiotic) on 1,2-dimethylhydrazine (DMH)-induced colon cancer in male S...
Article
Chlorpyrifos (CPF) is an agricultural pesticide and a potential food contaminant, which causes neurotoxicity. Here, we aimed at exploring the link between the repeated exposure to CPF and memory dysfunction in rats and the possible protective effect of kaempferol, a flavonoid with appreciable antioxidant and anti-inflammatory activities. Rats were...
Article
The chronic exposure to chlorpyrifos (CPF) pesticide induces several human disorders including hepatotoxicity. Alpha-lipoic acid (ALA) is a natural antioxidant compound found in plants and animals. The present study aimed to investigate the possible protective effect of ALA against CPF-induced hepatotoxicity and the possible underlying molecular me...
Article
Introduction: Patients with type 2 diabetes mellitus develop many complications including osteopenia, which is associated with high fracture risk. Osteocalcin is a non collagenous protein derived from the osteoblasts. Recently, it was found that osteocalcin enhances the pancreatic beta cell proliferation, insulin secretion and protection against t...

Hepatitis C virus (HCV) infection represents a serious health problem. The –174 G/C mutation in the pro inflammatory cytokine interleukin-6 (IL-6) is associated with developing liver diseases. Likewise, the S and Z mutations in the serine protease inhibitor α1-antitrypsin (A1AT) are associated with pulmonary emphysema and/or liver cirrhosis. We exp...

Alzheimer’s disease is a progressive neurodegenerative disease characterized by the accumulation and aggregation of extracellular amyloid β (Aβ) peptides and intracellular aggregation of hyper-phosphorylated tau protein. Recent evidence indicates that accumulation and aggregation of intracellular amyloid β peptides may also play a role in disease p...

HSPB5 (also called αB-crystallin) is a ubiquitously expressed small heat shock protein. Mutations in HSPB5 have been found to cause cataract, but are also associated with a subgroup of myofibrillar myopathies. Cells expressing each of these HSPB5 mutants are characterized by the appearance of protein aggregates of primarily the mutant HSPB5. Like s...

The human molecular chaperone protein DNAJB6 was recently found to inhibit the formation of amyloid fibrils from polyglutamine peptides associated with neurodegenerative disorders such as Huntington's disease. We show in the present study that DNAJB6 also inhibits amyloid formation by an even more aggregation-prone peptide (the amyloid-beta peptide...

Small heat-shock protein chaperones are important players in the protein quality control system of the cell, because they can immediately respond to partially unfolded proteins, thereby protecting the cell from harmful aggregates. The small heat-shock proteins can form large polydisperse oligomers that are exceptionally dynamic, which is implicated...

Question
I am using the same 1ry antibody , 2ry and ECL with the same dilutions?
Question
but I always see other bands around 120 , 100, 85 and 48 kDa even in the controls (untransfected cells) . these extra bands are endogenous APP or metabolic products or they are non specific bands? did anyone face this problem ?
Question
What concentrations or incubation times should I try in order to be able to detect AB aggregates inside my cells? Any hint will help.
Question
I need the recipe for making the gels and sample buffer, and electrophoresis settings.
