A Case Against Gun Control It seems to be all over the news these days. The next big mass shooting has occurred and the politicians are clambering for stronger regulations. Meanwhile, the American public goes into panic mode and flocks to the nearest gun store to buy anything and everything that soon might be ripped from the market. Time and time again, this same series of events occurs. Questions about how to fix this likely weigh heavily on people 's minds but, there seems to be no solution. Some
that play a role in cancer: oncogenes and tumor suppressor genes. Proto-oncogenes are regular genes that can become oncogenes if mutated and an oncogene is a gene that can lead to a tumor when mutated because it causes cells to divide unrestrainedly (Heidi 2008). On the contrary, tumor-suppressor genes slow down cell division. When tumor-suppressor genes do not function properly, cells can grow as rapidly as an oncogene (Heidi 2008). Tumor-suppressor genes involve the BRCA1 and BRCA2 genes that are
Reductionism is a method of explanation that assumes the workings of complex phenomena are reducible to the relationship of their simpler, fundamental, constituents. This practice is utilized in some form or another throughout nearly all fields of science: including physics, chemistry, ecology, sociology, medical sciences, etc. Reducing complex systems to the mechanisms of their parts is risky – it neglects properties that may emerge from the system as a whole. These emergent properties may be unpredictable
Introduction TP53, more commonly known as the Tumor Suppressor Gene is what protects a gene from over developing into cancerous cell. TP53 is responsible for regulating nuclear processes within the chromosome ultimately maintaining the cell's cycle and making sure it stays on its correct course, even assisting in apoptosis. The TP53 gene sends signals to make a protein called tumor protein p53 (or p53). This protein is the tumor suppressor itself, it regulates cell division by keeping cells from

The Genetic Update Conference was surprisingly interesting and fascinating. There were many thought-provoking topics of discussion at the Conference. One of those main topics was Cancer and Genes. This topic was very informative and helped further educate others about the role of Genetics on Cancer. According to Sam Rhine, tumor can be best defined as diseases in which a single cell acquires the ability to proliferate abnormally, resulting in an accumulation of progeny. Cancers are those tumors which
distilled all the existing research to depict the fundamental characteristics of cancer. Hanahan and Weinberge proposed six hallmarks shared among all cancers mentioned in this article includes supporting proliferative signaling, evading growth suppressor, resisting cell death, enabling replicative immortality, sustaining angiogenesis, and tissue invasion and metastasis. Four emerging hallmarks are also introduced in this article, depicting the current 10 underlying principles shared by cancerous
Thought to be an oncogene, a gene that has potential in transforming normal cells into tumor cells, p53 was regarded as the most prominent tumor suppressor gene [1]. P53 is a gene which signals apoptosis (programmed cell death) if a cell cannot be repaired due to an extensive amount of damage. As stated in the textbook, p53 regulation occurs by an E3 ubiquitin-protein ligase known as MDM2 [1]. "Controlling the controller" is a statement that describes the molecular interaction where the presence
Normally, tumor suppressor genes slow down cell division to repair damaged DNA or signals that the cells have to die. If the tumor suppressor gene isn’t functioning or turns off, it’ll cause DNA mutations. Since the cell won’t be able to slow down cell division, it begins to grow out of control and keeps dividing. They can be from genetics, but mostly acquired. P53 and INK4 genes are examples of tumor suppressor genes. Proto-Oncogenes, or Oncogenes (when mutated)
proteins - so that’s how we build ourselves. Mutations change those instructions, and that’s where things start to go wrong. Now, we know by this point that cancers usually come from mutations of two kinds of genes, called oncogenes and tumor suppressors. An oncogene starts out as just a normal gene that codes for proteins that signal the cell to grow. And normally, they just spend a lot of their time inactive, because growth is generally good, but cells

Hypomethylation of DNA and hyperacetylation of histones in the promoter region leads to successful transcription of the DNA. Therefore, any alteration in either of the two will disrupt the
(apoptosis). This process is tightly regulated by the genes within a cell’s nucleus. In cancer, as a result of genetic mutations, this process malfunctions, resulting in uncontrolled cell proliferation. Mutations in proto-oncogene or in a tumour suppressor gene allow a cancerous cell to grow and divide without the normal control imposed by the cell cycle. A change in the DNA sequence of the proto-oncogene gives rise to an oncogene, which
although it may be inherited or genetically unrelated [2]. Cancer occurs when mutations in the DNA cause uncontrolled cell proliferation and hence tumor formation. Cancer causing genes can be divided into two classes: 1.) Tumor suppressor genes 2.) Oncogenes. Tumor suppressors if underexpressed are unable to check cell proliferation, resulting in tumor formation. On the other hand, the same results if proto-oncogenes (the precursors of oncogenes) are overexpressed or activated. Isolating the causal
but more so for those with European than Asian values. Suppressors with bicultural Asian-European values were perceived as less hostile and detached than those with dominant European cultures. In addition, suppressors with bicultural values were more responsive than European counterparts. The study has strengths as it responds to an important gap in literature and tests how participants would actually suppress emotions and respond to suppressors. Nonetheless, the small
to have a separator column for ion separation and a suppressor column that reduced the conductance of the eluent used to elute the ions (Fritz and Gjerde 3). An alternative method was discovered where a single column could be used for the whole process by using eluent solutions that had naturally reduced conductance but had good eluting capabilities. The reason that led to the development of this single column IC was the resin in the suppressor column. Some of the analytes interacted with the resin
Inactivates its Tumor Suppressor Function in Cervical Carcinogenesis, is to investigate the mechanism by which the KLF4 gene is silenced in cervical carcinomas. Cervical cancer accounts for 250,000 female deaths every year. Developing therapies for cervical cancer has been limited due to the lack of genetic and epigenetic data of the mechanism causing the cancer. The KLF4 gene is a transcriptional regulator of cell growth and differentiation. It functions as a tumor suppressor in cervical cancer
Everyday students begin their day by listening to the Pledge of Allegiance. Some may speak the words, but do the people really understand what is being said? “One nation under god, indivisible, with liberty and justice for all”. The nation claims, as one, it ensures “liberty and justice for all”. However, the treatment towards certain groups, and the “extent” of liberty given to the people is limited. Thus, revealing America does not guarantee equal rights for all its citizens. Due to racial profiling
Hence this mechanism is repressive to transcription, by that enhancing genomic stability. However, there exist “CpG” islands that are associated with gene promoters that escape methylation hence stability. Hypermethylation of CpG islands at tumor suppressor genes turns them off, while hypomethylation leads to the instability and inappropriate activation of oncogenes and transposable elements. Methylation can be directly related to genetic mutations, an example of this case is methylated cytosine. Methylated
that affect women and ovarian cancer is the fourth most common cause of cancer mortality in American women1. These cancers are triggered by germline mutations on the C-terminal of a gene called BRCA1 (or “Breast Cancer 1, Early Onset Gene”) tumor suppressor. The BRCA1 gene is located on the long (q) arm of chromosome 17 at region 2 band 1, consists of 24 exons and encodes a multidomain protein of 1863 amino acid residues in human2. The BRCA1 proteins produced from BRCA1 gene help preventing cells from
many opinions thought to be true have later been proven to be false such as slavery being accepted to it being inhumane. His strongest argument for this claim is that to suppress an opinion, one must be certain that it is incorrect and that the suppressor is infallible. There are many issues that arise when one tries to suppress an opinion, whether that opinion be true or not. A true opinion should not be suppressed, even if it is not widely believed in. Others are free to disagree with it, but
