Hence, the FoF1-ATPase is a vital target for drugs that treat acid-related diseases (Spugnini and Fais, 2017; Abe et al., 2018), such as omeprazole targeting ATPase for gastric ulcer disease (Sachs, 1984), bedaquiline targeting Fo ring of Mycobacterium tuberculosis for tuberculosis (Preiss et al., 2015), and some proton pump inhibitions for cancer (Spugnini and Fais, 2017). Here, DNAH8 is linked to gastric ulcer.
