expand this into 1000 words for a conclusion of a report. context is that the title is Identification of Differentially Expressed Genes in Breast Cancer Using RNA-Seq. Also STATE THAT THE RESULT SUPPORT THE HYPOTHESIS. "In conclusion, the RNA-Seq analysis has identified several genes that are differentially expressed in breast cancer. These genes may play important roles in the development and progression of breast cancer and could potentially serve as targets for therapeutic intervention. The comparison underscores the complex interplay between TONSL expression and gene regulation, highlighting distinct gene expression profiles in primary cells versus TONSL-overexpressing cells. These findings provide valuable insights into the regulatory roles of TONSL and its potential implications for cellular physiology and disease mechanisms. Understanding the differences in gene expression dynamics between primary cells and TONSL-overexpressing cells is crucial for elucidating the molecular…
how do i expand this into 1000 words for a result section of a report The objective is to interpret the results of an RNA-Seq analysis to identify differentially expressed genes in breast cancer using figure 1. The data provided includes gene symbols, chromosome location, start and end points, strand, fold change, log2 fold change, p-value, and false discovery rate (FDR). The RNA-Seq analysis has identified several genes that are differentially expressed in breast cancer. These genes are located on various chromosomes and have varying levels of fold change, indicating the degree to which their expression levels differ between normal and cancerous cells. The gene with the highest fold change is EYA4, located on chromosome 6, with a fold change of 3604.4176. This indicates that the expression of this gene is over 3600 times higher in cancer cells compared to normal cells. The log2 fold change is 11.81555, which is a measure of the magnitude of the difference in gene expression. The…

Glioblastoma multiforme (GBM) is the most commonand aggressive form of brain cancer in humans.Without any treatment, the mean survival rate is aboutthree months. Even with standard treatments such assurgical resection, radiation, and chemotherapy, themean survival rate is between seven and 14 months.GBM tumors differ in their spectrum of geneticchanges, and these changes may influence the effectof particular treatments. Answer the following questions about the relevance of particular mutations toparticular treatments and outcomes.a. Biopsies of about 20% of GBMs show the expression of a certain mutational variant of the EGFR(epidermal growth factor receptor) protein calledEGFRvIII. The same cancerous cells of theseGBMs also show the expression of normal, wildtype EGFR. Is the gene encoding EGFR a tumorsuppressor gene or a proto-oncogene?b. It is very difficult to induce cells expressingEGFRvIII to undergo apoptosis. If you werea radiologist treating a patient with a GBMthat expresses…
Below is a figure (here called Figure 1) from “Prognostic Significance of CpG Island Methylator Phenotype and Microsatellite Instability in Gastric Carcinoma,” by An et al., published in Clinical Cancer Research in 2005. The authors look at five microsatellite loci (BAT 25, BAT 26, D2S123, D5S346, and D17S250) in normal (N) and tumor (T) tissue from patients with Gastric Carcinoma. They amplify the loci by PCR and then instead of using standard agarose gel electrophoresis, they run the PCR products through capillary gel electrophoresis and detect bands as they pass a laser near the positive charge terminal. The x-axis in these plots is the time at which the band passed the laser (aka size of the PCR product) and the intensity of the peaks represents the amount of DNA in that band A. Which patient- 18, 30, or 1- shows the most microsatellite instability? Which patient shows the least? How do you know? B. In which repair pathway is it most likely that you will find the driver mutations…
Question -The FDA has authorized the use of direct-to-consumer testing for three mutations in BRCA genes that elevate cancer risk, but cautions that a negative result does not rule out increased cancer risk. How can this be true? A. It is impossible to trust companies that are selling genetic tests. B. They have a conflict of interest, and so the tests should be used for entertainment value only C. These tests are not highly accurate, and false negatives are possible. Individuals with a family history should have a negative result confirmed with a different test to be sure they are truly at low risk of developing cancer There are more ways to get cancer than a mutation in the BRCA gene. D. The test only detects three out of more than 1,000 known BRCA mutations. This means a negative result does not rule out the possibility that an individual carries other BRCA mutations that increase cancer risk..
