WebApr 7, 2024 · Normal genes that help cells grow, called proto-oncogens, can become "oncogenes" (or those with the potential to cause cancer) when mutated and code for proteins that drive the growth of cancer. By contrast, tumor suppressor genes are genes within the cell that tell cells to slow down and stop growing and repair damaged DNA. crypto sites that pay interestsWebApr 14, 2024 · Abstract. Chronic myeloid leukemia (CML) is a hematological malignancy mainly caused by the Bcr-Abl oncogene that results from the reciprocal translocation between human chromosome 9 and 22, and occurs in more than 90% of CML cases.
