Cellular Essay Samples and Topic Ideas
cellular processes and molecular changes that underpins physiological or pathological states. Radical developments in the field of molecular biology have paved the way for practicing molecular medicine. Hence, I am interested for pursuing the Masters program in Molecular Medicine at your esteemed institution. The Masters program would increase my competence in the field of cellular and molecular biology. Such skills and competence would help me in undertaking research activities in molecular medicine and also for aiding me in my clinical practice. My interests in molecular medicine pivot around management of cancer. I have done by baccalaureate in medicine and surgery (M.B.B.S) from the...

cellular apoptosis (Jansen et al. 885), although Liu, Zhao and Li (1793) it is best used in combination with other antitumor agents. Gemcitabine has been used to treat different cancer forms to include lung, breast, cervical and pancreatic cancers. In this respect, the proposed research study intends to evaluate the degradation characteristics of gemcitabine injection with the intention of identifying the most effective, stable and soluble formulation of the drug to guarantee favorable results. Gemcitabine has been identified as the compound of interest since it has the potential to counteract cancer effectively. In fact, Anliker et al. (716) report that gemcitabine is active in inhibiting tumor...
cellular molecular and genetic mechanisms. Histological and Cellular Mechanisms Different auto-regulatory mechanisms protect the kidneys from a systemic elevation in blood pressure. The auto-regulatory mechanisms which operate in the kidneys are glomerulotubular feedback and tubuloglomerular feedback (Shankland, 2006). Autoregulation helps to maintain the glomerular filtration rate and the renal arterial pressure. The extent of renal damage due to hypertension is directly proportional to the sustained elevation of blood pressure within the renal microvasculature (Romagnani & Remuzzi, 2013). If the afferent arterioles are intact, the auto-regulatory mechanisms prevent damage to the renal...
cellular extracts were then immunoprecipitated and the resulting material analyzed by western blotting for the PCAF and Tat. The authors also conducted another test by replacing with arginines the Tat residues K50 and K51. Further assessment of the PCAF bromodomain role in Tat activation involved raising “a polyclonal antiserum using recombinant PCAF bromodomain in Escherichia coli” (Dorr et al. 2716). The study results and consequent discussion present the experimental evidence of the specific interaction between acetylated Tat and PCAF, which is a direct process under the mediation of the PCAF's bromodomain. This interaction and subsequent synergy lead to activation of the HIV promoter. Their...

cellular responses. However, it is still unclear on how the molecular processes and mechanism by which an activation of a particular GPCR on the same ligand allows coupling to many G proteins subsets (Soto et al. n.p). An experiment conducted proved that PAR1 mutant which was deficient in glycosylation at extracellular loop 2 (ECL2) was more reliable at stimulating Gq-linked phosphoinositide communications in comparison with glycosylated wild-type receptor. In another event, wild type PAR1 was more efficient at G12/13 dependent RhoA activation concerning the mutant receptor not glycolysed at ECL2.Another experiment involving the use of endogenous PAR1 deglycolysed using tunicamycin, a glycoprotein...
cellular division in both mitosis and meiosis. Some activities take place during metaphase; the nuclear membrane disappears, therefore, the chromosomes are free in the cytoplasm. Spindle fibers elongate fully and are attached to the centrioles at opposite poles. The chromosomes line up themselves at the center of the spindle fibers and are connected to the spindle fibers by the centromeres ready to migrate to the opposite poles. Question 5 In mitosis, diploid cells are produced because the cell contains the same number of chromosomes as the body cell, whereas in meiosis haploid cells are produced because they contain half the number of chromosomes as the body cell. Question 6 Cellular DNA is...
cellular damage. It has also been found that carotenoids are instrumental in boosting cardiovascular and male reproductive health. Work Cited Krishnan, Anagha, et al. "Metabolic and photosynthetic consequences of blocking starch biosynthesis in the green alga Chlamydomonas reinhardtii sta6 mutant." The Plant Journal 81.6 (2015):...
