Oncogenes are mutated forms of normal genes known as proto-oncogenes.

Proto-oncogenes regulate cell development and division, whereas oncogenes encourage uncontrolled cell growth and division, which results in the establishment of a malignant tumor.

In numerous ways, the presence of an oncogene can result in the creation of a malignant tumor. For starters, oncogenes can generate proteins that promote cell division and prevent cell death. These proteins can also disrupt normal signals that control cell growth and division, resulting in uncontrolled cell proliferation.

Second, oncogenes can disrupt the repair processes that repair damaged DNA in cells, resulting in the accumulation of mutations and the progression of cancer.

Third, oncogenes can stimulate the formation of new blood vessels to feed the expanding tumor, a process known as angiogenesis. This procedure provides the tumor with the nutrition and oxygen it requires to continue growing and spreading.

Poisoning proton pumps would reduce anion uptake.

Proton pumps are responsible for maintaining a low pH environment within cells, which is essential for many cellular processes, including the transport of anions. Anions are negatively charged ions that are transported across cell membranes with the help of transport proteins.

These transport proteins rely on the proton gradient generated by proton pumps to function properly. If proton pumps are poisoned, the pH of the cell will increase, which can lead to dysfunction of anion transport proteins and a subsequent reduction in anion uptake. This can have significant physiological consequences, such as electrolyte imbalances and impaired cellular function.
