Which of the following are true for the Bax gene? Select all that apply The Bax gene is a proto-oncogene The Bax gene is a tumor suppressor gene In cancer or transformed cells, the Bax gene mutation would be dominant, and a gain of function mutation In cancer or transformed cells, the Bax gene mutation would be recessive, and a loss of function mutation Jm

The p53 gene is a tumor-suppressor gene while p634 gene is an oncogene. Mutation in either one can result in the transformation of a normal cell into a cancer cell. Explain the difference between the functions of the two proteins and how their mutation can lead to cancer development.
Which of the following types of mutations would be advantageous to a cancer cell (select all that apply)? A. An inactivating mutation in a tumor suppressor gene B. Methylation of the promoter of a tumor suppressor gene C. An inactivating mutation in an oncogene D. Mutation that inactivated DNA repair gene E. An inactivating mutation in an oncogene
Which of these events do you think is likely to promote tumorigenesis in affected cells? Group of answer choices DNA methylation of the promoter region of a tumor suppressor gene Hypermethylation of transcription factors that antagonize Wntsignaling Open chromatin in the region of of DNA harboring an activating mutation of beta-catenin All of these
p53 gene, as is the Rb gene, is a tumor suppressor gene. p53 protein binds to DNA leading to the simulation of p21 that work together with cdk2. When p21 is defective and cannot joined to cdk2 the cell cannot pass through to the next stage of cell division. Mutated p53 cannot bind to DNA in an effective way, and therefore the p21 protein is not available to act as the 'stop signal' for cell division. Thus cells divide uncontrollably, and form tumors. Hi, can you please elaborate on this: based on the info above, what is the relationship between genetics and environment in the development of these type of cancer. Which factor (genetics or environment) is playing a larger role in the generation of these types of cancers?
BAX proteins stimulate apoptosis. Mutations in BAX genes can help developing cancers but not necessarily trigger a tumor. This is because mutations in BAX do not contribute to tumorigenesis, but BAX can prevent the formation of a tumor mutations in BAX may over-stimulate apoptosis mutations in BAX contribute to tumorigenesis only with other inhibitors of apoptosis mutations in BAX prevent the formation of tumors
