cells or to the ECM. Within the anchoring junctions there are the adherens junctions which wrap around a cell near its apical surface and bind it to its neighbouring cells. The membranes of these junctions contain cadherins that are linked to the actin filaments of the cytoskeleton. Cadherins are a family of glycoproteins that depend on calcium ions to function. (G. Karp) Desmosomes are small circular shaped structures that join cells together by functioning as anchor sites for intermediate…

“A muscle is a tissue composed of cells or fibres, the contraction of which produces movement in the body.” (Dictionary) There are three different types of muscle; voluntary skeletal muscle, involuntary smooth muscle and cardiac muscle. Muscles have many different functions within the body. One function of muscle is movement. It is the only tissue in the body which is able to contract and therefore can move more than other body parts. Another function is the maintenance of posture. The muscles…

2. Materials and methods 2.1. Chemicals Zingerone was obtained from Alfa Aesar, Heysham, UK. Cisplatin, Bradford reagent, trichloroacetic acid (TCA), thiobarbituric acid (TBA), reduced glutathione (GSH), glacial metaphosphoric acid (Gmpa), 5,5ˊ-dithiobis-(2-nitrobenzoic acid) (DTNB), proteinase K and agarose were purchased from Sigma-Aldrich Co, MO, USA. All other chemicals and solvents used were of the highest purity grade available. 2.2. Animals Sixty Adult male albino rats (180-200g) were…

Hypertrophy means that the muscles size will increase. Hypertrophy happens when the amount contractile proteins (Actin & Myosin) increase inside the muscle cells so the way in which the can contract is far greater.the amount of fibres in the muscles remain the same mount. Statistically males have a greater chance in muscle bulk due to higher levels of the hormone testosterone. As it relates to skeletal muscle, hyperplasia defines muscle growth due to an increase in the quantity of muscle…

cell’s bones, muscles, and ligaments by supporting cellular structures and providing the machinery to generate various cell movements (Hopkins, 2010). There are three types of rods in the cytoskeleton, and each filament has specific role microfilaments Actin filaments are considered to be the most abundant in the cell; they also create contractile forces (Hopkins, 2010). Secondly, the Microtubules help with the duplication and the division of in the cells. Lastly, Intermediate filaments are use…

cloning, etc. (Kelly, 2016). This allows for the ability to conduct DNA analysis revealing varying compositions and properties. For the following experiment the genomic DNA from Drosophila melanogaster, was utilized to be cloned and sequenced for either actin or 18s rRNA. In order to clone and sequence the specific section of DNA 9 specific steps had to be conducted and they are as follows: extraction/purification of DNA, amplify the gene utilizing PCR, ligate the product from PCR into plasmid…

I. The most basic unit of life is the cell. All living things are composed of cells. Cells may only from through a process of division and replication of previously existing cells. Cells are microscopic; however their structure is complex. All types of cells possess a plasma membrane which separates its contents from its surroundings. . There are two types of cells: prokaryotic and eukaryotic. a. Prokaryotic cells are simpler than eukaryotic cells. Within prokaryotic cells are bacteria cells…

Since reverse transcription is non-specific to RNA molecules, there is the possibility of having mRNA that code for proteins other than Actin. To solve this problem, there were specific primers that were used in PCR, primers 1 and 2 (forward and reverse, respectively); these primers are specific for gene of interest. The primers are Actin forward (1) and Actin reverse (2). During preparation of the reaction, most of the time the reagents are left on ice, this is to prevent the primers and…

sodium ions exchanging start to spread both sides of muscle cell membrane to form the action potentials, and long with the cell membrane so that both sides of the terminal cistern will release Ca2+, Ca2+ and troponin binding to change tropomyosin, let actin exposed binding site to the cross bridge.…

for it to be looked under the confocal microscope to view the mitochondria and nucleus. After staining the slice they treated the tissue with 4% formaldehyde and 0.05% ethidium bromide in a NaCl solution. In some of the experiments it was evident actin was visible under the fiber…
