Biochem/physiol Actions

U-104 is an inhibitor of CA IX that binds only to CA IX under hypoxic conditions in vivo. The binding results in significant inhibition of tumor growth and metastasis formation in both spontaneous and experimental models of metastasis. U-104 reduces the medium acidity by inhibiting the catalytic activity of the CA IX. It binds specifically only to hypoxic cells expressing CA IX.

Fibrolamellar carcinoma (FLC) is a rare, therapeutically intractable liver cancer that disproportionately affects youth. Although FLC tumors exhibit a distinct gene expression profile, the chromatin regulatory landscape and the genes most critical for tumor cell survival remain unclear. Here, we

The mechanism of proton pump inhibitors (PPIs) suppressing intestinal Mg2+ uptake is unknown. The present study aimed to investigate the role of purinergic P2Y receptors in the regulation of Mg2+ absorption in normal and omeprazole-treated intestinal epithelium-like Caco-2 monolayers. Omeprazole
