Please answer all questions
1. What can mutation lead trastuzumab resistance with lapatinib sensitivy from HER2+ cancers.
2. What can another oncogeneic mutation be which lets HER2+ tumors being positive, have resistance to the lapatanib.
*NOTE: Kindly repost for other question. Dear Student as per the guidelines we are supposed to answer only one of the question. So please repost the question for getting the answers for others too thank you.
1.Lapatanib is a HER2 kinase inhibitor and it is used for people with over breast cancer who will have HER2 kinase in excessive as it will inhibit the HER2 kinase it is given to people with over breast cancer.
* JIMT-1 and MDA453 are the cells which possess PIK3CA mutation that is resistance to trastuzumab also reduced sensitivity to lapatinib.
*So these mutations will cause sensitivity to lapatinib these will make it to sensitive to HER2+ cancers .

Group of answer choices True FalseThis is homework not a test! From NTSA case study https://static.nsta.org/case_study_docs/case_studies/cystic_fibrosis.pdf Please help with questions 2, 3 and 4 of part four 2. "The successful use of gene therapy to cure SCID syndrome (2000) is hoped to be a permanent cure for those patients because a good copy of the problem gene was inserted into the patients' blood stem cells in the bone marrow (hematopoietic stem cells). Once white blood cells enter the blood stream they have a limited life span, on the order of a few week to months. The blood stem cells are the cells that create more white blood cells to replace those that are lost. If the gene was only inserted into the circulating mature white blood cells, the patient would only be temporarily cured until those cells were used up or died." The current gene therapy approaches to cure CF involve inserting a functional CFTR gene into the mature epithelial cells of the lungs. In light of the preceding paragraph, do you think that…My follow up question is Are the genes mention previously important to adencarcinoma tumours in colorectal cancer in humans which is MSH1 MSH2.
