Essay On Cell Morphological Features

While completing a BS degree in Cell and Molecular Biology at the University of Michigan, I was able to focus on a small independent project at Wicha lab, investigating CSC epithelial-mesenchymal and mesenchymal-epithelial transition states in breast tumors, their clinical relevance, and how scientists may push either transition in various cell lines. Throughout this project, I became familiar with planning and running molecular biology experiments, which requires detailed knowledge especially in analysis, trouble-shooting, and developing further

You may use the lab manual, pre-lab lectures, and credible internet resources, however you may not use your cell bio lab classmates as a resource. You will most likely see this material again on the Final and I highly encourage you to work individually and seek help from myself or your TA. Plagiarism will result in an automatic zero.

1. The feature that most clearly separates eukaryotes from prokaryotes is the presence of _______ in eukaryotic cells.

On 07/11/2015 at the Lower Buckeye Jail (located at the above listed address) I was assigned as the floor officer for Tower 12. At approximately 1555 hours, Inmate Asad, Sami T188658 (V1) came out to Level 1 core stating that he had been hit in the back of the head multiple times inside his cell in T12 B pod. Inmate Asad was placed into the level 1 holding tank awaiting medical.

Thus an interdisciplinary approach should be utilized as a broad range of scientific discipline from biochemistry to informatics which will help us to identify and understand the mechanism for cancer progression and its prognosis. With the rapid changes in the technology, there has been various challenges which have come into the picture due to regulatory oversight and legislation. One of the major challenges is to manage large amount of data generated via assays thus it requires massive computational resources for data storage, processing and interpretation. Certain informatics resources such as ClinGen and ClinVar database of the National Center for Biotechnology Information (NCBI) has provided us with easily accessible data. The identification and routine deployment of molecular markers to improve classification of indeterminate lesions will be of great benefit to patients and surgeons and will reduce costs to the health care system by limiting unnecessary surgical procedures. More multidisciplinary research, closer collaborations is required between drug and cancer biomarker developers, clinicians, biologists, biostaticians and IT professionals, so to develop cancer biomarkers to improve patient outcome as well as to help the clinician in rapid clinical decision

Drug discovery is expensive and challenging. One such challenge is identifying clinically active cancer targets out of a huge number of biomolecules that are known to have a role in cancer initiation and progression. Below I have outlined the key information that should be gathered about a novel drug target, the experiments that are required to validate such a target, and discussed what needs to be considered when deciding whether a target has been validated.

Integrated motif activity response analysis (ISMARA) - a bioinformatic tool to predict altered transcription factor activity - predicted the E2f family as upregulated in ENT1-/- AF tissue. E2f transcription factors are associated with cell cycle progression from G1 to S phase.14 Indeed, the expression of numerous E2f transcription factors was significantly upregulated in ENT1-/- AF tissue. We will further investigate the role of E2f factors in ENT1-/- AF tissues using a combination of RT-qPCR, immunohistochemistry and western blotting to examine tissue specific changes in the IVD and their association with markers of cell proliferation (i.e. Ki-67, PCNA). Further, we will use established protocols for AF cell isolation and culture to assess whether changes observed in vivo are recapitulated in vitro. Additionally, shRNA knockdown in WT AF cells will be used to identify specific E2f members responsible for increased cell proliferation, and genes downstream of altered E2f

P1 – Describe the microstructure of a typical animal cell and the functions of the main cell components. A typical animal cell is seen as a tiny, three dimensional sac which is in fact made up of many components, each as important as the other. The microstructure of an animal cell was in fact uncovered mainly through the use of both cell fractionation and electron microscopy. Each main component has its own, individual function which helps a cell to function and maintains the cell membrane. The components that I will be describing include the cell membrane, nucleus, cytoplasm, mitochondria, lysosomes, Golgi bodies, centrioles, endoplasmic reticulum (both smooth and rough) and ribosomes.

1. Proto-oncogenes and tumor suppression genes are both used to help regulate the cell cycle. Tumor suppression genes produce proteins that inhibit cell division, and proto-oncogenes produce proteins that stimulate cell growth and division. The balance between the activities of these two genes ensure cells are dividing at a suitable rate for their body. Mutations affect these cells in two different ways. When mutation occurs, proto-oncogenes become oncogenes. Oncogenes promote excessive growth and causes the cells to divide excessively, even when it is unnecessary for the cell to keep dividing. When mutation occurs for tumor suppression genes, the tumor suppression genes can become inactive. Because tumor suppression genes inhibit and lessen

Good morning. This is Larry Lysosome here. I work at The Cell Corporation. My job here at Cell Co. is to recycle the other malfunctioning parts of the cell and return their nutrients back into the cell. I write to you because I am aware that you will soon be firing some employees here at Cell Co. and wanted to inform you that Cell Co. would be a complete mess without me (no pun intended). I'm a vital part of the corporation and it would be nearly impossible for the other organelles as well as you Mrs.Eukaryote to work properly without me. So I ask that you take a moment to listen to me and consider what I have to say.

Cells are some of the smallest organisms around. All living things consist of cells, and yet they are invisible to the naked eye. Cells are the basic structural and functional units of life. Cells are made up of many different parts which allow them to function properly.

Carol W. Greider is a cell biologist who has discovered the enzyme telomerase in 1984 which she won the nobel prize award. Greider pioneered research on the structure of telomeres, the ends of the chromosomes. She works in a lab which can work with DNA bases to the ends of chromosomes. The thesis she made was “The identification of a specific telomere terminal transferase activity in Tetrahymena extracts.”

Results: We found that minoxidil stimulates the survival of bulge and DP cells. Kras, Akt, Erk, Shh and β-catenin mRNA levels were significantly upregulated in response to minoxidil treatment in the bulge and DP cells. Apoptotic cells significantly decreased by HPL treatment in DP cells. Moreover, HPL mediated Erk up-regulation in the bulge and DP cells. HPL-treated bulge regions exhibited significantly increase in β-catenin mRNA
