patients (1). Many pathways that involved in DN have been postulated such as hyperglycemia, oxidative stress (OS) and activation of protein kinase C (PKC) (2-4) (Table 1). The up-regulation of the receptors for AGE (RAGE) has been implicated as a major mediator in the development and progression of DN. Renal fibrosis characterized by accumulation of extracellular matrix protein results in CKD including DN. It was found that transforming growth factor (TGF-β1) signaling pathway plays a key role…

anatomically observe the location of a specific protein or antigen in cells by the use of a specific primary antibody that binds to it. A staining reagent or chromagen is used to help detect certain proteins used in this experiment, called 3,3'-Diaminobenzidine (DAB). 3,3'-Diaminobenzidine (DAB) DAB, a derivative of benzene, is an organic compound, which is both chemically and thermodynamically stable, used in the staining of nucleic acids and proteins, most commonly for immunohistochemical…

leucine to proline at amino acid position 1544(Ashcroft, 2005). This mutation simply reduce the activation of the channel by stimulatory nucleotide MgADP, as the NBDs sensitivity to this nucleotide is greatly/entirely lost. The failure of the channel activation means the open state of the channel pore is greatly reduced/blocked. This occurs as the inhibitory nucleotide (ATP) would have higher affinity for the channel than the activating nucleotide (MgADP). Closure of the K+ channel leads to…

alterations can cause a range of phenotypic effects from no effect to cell death for essential genes. Disruptions that result in an essential phenotype are typically important to core activities of the cell, such as energy metabolism, DNA replication, or protein processing. Mutations can also have complex buffering effects, where a mutation that would normally have a phenotypic effect but does not while in the…

Downstream Targets Due to the lack of developing an effective Ras treatment, some have turned to targeting downstream effectors of Ras. Downstream effectors have a critical role in Ras carcinogenesis and are commonly found in KRAS mutated cancers. The most intensely targeted pathways are the Raf-MEK-ERK (MAPK) and PI3K-AKT-mTOR signaling pathways. Raf-MEK-ERK MAPK signaling is initiated through receptor tyrosine kinases after their activation by growth factors (Mccubrey 2006). Once Ras is in its…

discover what kinds of amino acids your body needs and when to take them. It’s amazing that so many bodybuilders know so little about amino acids considering how vital they are to overall health and muscle growth. Muscle building amino acids are what proteins are made out of; therefore they ultimately become part of your muscles and the rest of your body. They affect many different functions in the body including how much energy we have, our mood as well as muscle development and recovery.…

are protein molecules that receive chemical signals in the form of ligands and induce responses at cellular level. They are localized at the cell surface, cytoplasm or the nucleus, depending on their amino acid sequences. In addition to using these three different localizations to categorize receptors, the types of action of receptors are also used as a mean of classification. The four main classifications of receptors are: 1. Ionotropic (or ligand-gated ion channel) receptors, 2. G-protein…

A. What is the purpose of a polymerase chain reaction (PCR)? List the four main components of a PCR. (2 points) The purpose of a PCR is to make large amounts of DNA segments from just a specific DNA sequence. This method is used to scientifically prove if a suspect of committing a crime is truly the person who committed the crime. The four main components of a PCR are: DNA from a sample, nucleotides A, T, G, C, DNA polymerase, and primers. B. What is gene expression? List the two steps of…

in kilobases) (1.2+0.7+0.4+3.1) = 5.4 kb. d) RNA Protein Truncation mutation in exon 2 Same length, same amount of RNA produced. Shorter in length (due to earlier stop codon), same amount of protein produced, usually changes the protein to non-functional, though not always. 3bp in frame deletion in exon 1 Shorter in length by 3pb, same amount of RNA produced. Shorter in length, same amount of protein produced, usually causes the protein to become non-functional, though not always. Splice…

cell growth, cellular differentiation, cell adhesion, the movement of cells and the death of cells. The body is unable to produce ceramidase with Farber’s disease, thus causing the buildup of ceramide. A gene is a section of DNA that codes for one protein. When there is a mistake in the…
