An Overview of Heavy Chain Ferritin in Cancer
FRONTIERS IN BIOSCIENCE-LANDMARK(2023)
Abstract
As a spherical protein that acts as a repository for intracellular iron, Ferritin is the most important iron storage form and is known to influence tumor immunity. Unbound ferritin is composed of 24 subunits, made up of ferritin light chain (FTL) and ferritin heavy chain (FTH). Ferritin can be automatically put together to form hollow nanocages that measure 12 nm around the outside and 8 nm around the inside. Cancer causes the second-most deaths worldwide, effective elimination of tumor cells while protecting normal cells is the foundation of modern tumor therapy. To this end, the innate tumor-targeting activity of human FTH1, first identified ten years ago, is highly appealing. Unmodified human FTH1 binds to its receptor, transferrin receptor 1 (TfR1), which is frequently overexpressed in cancer cells. FTH1-TfR1 binding permits improved drug efficacy by promoting ferritin-mediated targeted delivery. In addition, FTH is also associated with the prognosis of multiple typies of cancer. The level of FTH1 is significantly and positively correlated with the infiltration of tumor-associated macrophages. FTH1 also plays an important role in regulating the tumor immunity of solid cancer. As such, FTH1 has been extensively applied in the targeted delivery of anticancer drugs, diagnostic molecules (e.g., radioisotopes and fluorophones), and inorganic nanoparticles (NPs) to tumors.This article reviews the role of FTH in cancer and its potential as a therapeutic target.
