Tumorigenesis - Study guides, Class notes & Summaries

NBME PATHOLOGY EXAM WITH LATEST VERIFIED QUESTIONS AND 100% CORRECT ANSWERS GRADED A+ Apoptosis: - ANS-Programmed cell death. REQUIRES ATP. Can occur via the intrinsic or extrinsic pathways, both of which involve activation of cytosolic caspases which mediate cellular breakdown. ***Unlike necrosis, apoptosis does not involve significant inflammation. Involves eosinophilic cytoplasm, cell shrinkage, pyknosis and basophilia, membrane blebbing and karyorrhexis, and formation of apoptot...

Answer the following questions as if you were explaining them to a layperson (non-scientist). Your answers should be accurate but should not be too detailed or use jargon that a non-scientist would not understand. -What is cancer? -What causes cancer? -How can we treat cancer? - Answer--Cancer is the abnormal and uncontrolled growth of cells. It's a genetic disease that occurs when there are mutations in the DNA, and it can occur over the lifetime of an organism. -Cancer can be caused by...

Notes from Onc 401 explain many different tumor suppressors and oncogenes. Many different genes and their functions are explained, as well as cancer steps that are explained in full detail. Many experiments done are listed with the purpose and findings, as well as pictures modeling experiments or microscopic images. The overall goal of this course is to explain tumorigenesis and its ability to be a multi-step process. DNA damage and repair, as well as chromosome abnormalities, are explained. An...

A4M Practice Test 37 Questions with Verified Answers 1. Identify the true statement(s) concerning the role of mitochondria in longevity, aging, and disease. a. Decreased mitochondrial function results in increased oxidative damage, caused by free radical formation combined with a decrease in antioxidant enzyme system activity. b. Maternal transmission of mitochondrial genomes is a factor in differences in longevity between male and female organisms (Drosophila model) c. Alteration of the e...

BIO 235 HW Questions And Answers All Correct Why do mutations in genes that encode DNA-repair enzymes often produce a predisposition to cancer? A. The loss of DNA-repair enzymes makes a cell more susceptible to viral infection. B. Cancer is the result of an accumulation of mutations in tumor-suppressor genes and proto-oncogenes and a deficiency in DNA repair can accelerate this process. C. Genes for DNA-repair enzymes are usually genetically linked to proto-oncogenes on chromosomes, so muta...
