In a recently published paper in Proc Natl Acad Sci USA, Fang et al. elegantly demonstrated that doxorubicin treatment or transient ischemia/reperfusion in mice triggers ferroptosis, a distinctive form of necrotic cell death marked by iron-dependent lipid peroxidation, which is the main underlying mechanism in the pathogenesis of cardiomyopathy.

In 2016, heart disease was the leading cause of death for both men and women, accounting for over 600,000 cases annually in the United States alone. While the loss of terminally differentiated cardiomyocytes is a key event in the pathophysiological process of cardiac disorders, such as cardiomyopathies, the molecular mechanisms underlying cardiac cell death are incompletely understood.

Ferroptosis is a recently discovered, pharmacologically amenable form of regulated necrosis that is implicated in a myriad of pathophysiologically degenerative conditions including ischemia/reperfusion injury (IRI), acute kidney failure, neurodegeneration and hemochromatosis.1,2 In terms of morphological, biochemical and genetic traits, ferroptosis is distinct from other cell death routines such as apoptosis, necroptosis or autophagy. One of the hallmarks of ferroptotic signaling is iron-dependent lipid peroxidation, which precedes the execution of cell death. Therefore, efforts to prevent ferroptosis in pathological contexts have focused on the use of radical trapping agents, such as Ferrostatin-1 (Fer-1) and Liproxstatin-1, as well as iron-chelating agents.3,4

In terms of the subcellular localization of free iron release and lipid peroxidation, the authors found significant accumulation of free iron and lipid peroxides in mitochondria compared to the cytosol in the hearts of DOX-treated animals. Additionally, administration of the mitochondria-targeted antioxidant mitoTEMPO yielded significant cardioprotective effects compared to its untargeted version (TEMPO). While the relevance of mitochondria in ferroptosis is currently still under debate,7,8 lipid peroxidation in the context of DOX-induced cardiotoxicity is likely confined to mitochondria.

Interestingly, although iron overload-induced ferroptosis seems to be a major contributor to the pathology of DOX-induced cardiomyopathy, blocking necroptosis in mice by knockout of receptor interacting serine/threonine kinase 3 (Ripk3) resulted in increased survival rates compared to Fer-1 treatment alone. This effect is consistent with previous observations demonstrating the simultaneous involvement of distinct cell death pathways in tissue damage.9 In fact, a recent study investigating acute kidney injury was able to show that regulated necrotic cell death events may proceed in a chronological order.10 Therefore, one may speculate whether iron overload-induced ferroptosis is the initial trigger for organ damage in DOX-induced cardiomyopathy followed by secondary necroptosis, presumably activated via necroinflammation.11

In summary, in their most recent paper, Fang et al. provide intriguing insights into the role of HMOX1 as the major culprit for iron release in DOX-induced cardiotoxicity and draw for the first time an in vivo link between cardiac cell death and ferroptosis induced by iron overload. While the regulation of HMOX1 in ferroptosis is still considered pleiotropic as both protective and potentiating effects have been reported,12 it remains to be clarified whether distinct tissue and disease contexts are implicated.

Hence, the data presented by Fang et al. advocate for the development and exploitation of ferroptosis inhibitors as a new and promising therapeutic strategy to prevent cardiomyopathy induced by DOX, IRI and perhaps other insults. Future studies are thus warranted to explore the clinical implementation of these important findings for the treatment of heart disease.

The Iron Imprisoner is an Unversed that is found in Kingdom Hearts Birth by Sleep. It is one of the bosses at Mirage Arena. When it is first fought, it is chained and imprisoned in a gibbet, but it gradually releases itself over the course of its battles.

The Iron Imprisoner is a large, armored Unversed with four different forms. In its first form, the Iron Imprisoner I's lower body is locked in a black gibbet with silver highlights and several black, diamond-shaped gems set in it. Its arms, which are covered in black armor with two blue gauntlets, are bound by four red chains. Only its head, encased in a helmet that is light grey on its right half and grey on its left half, is free to move. It has jagged, black horns on either side of its helmet, though they are not of the same shape. The right horn is somewhat straighter and more horizontal, while the left horn hooks upward sharply. Its eyes are red, set in an angry expression, and slightly uneven.

The Iron Imprisoner II is identical to its first form, save for two significant changes. The Iron Imprisoner's chains are gone and its arms are free, making its gauntlets and red collar clearer. It is also now wielding a large, red and black hammer with spikes on its head. The handle of this hammer is tan and the pommel is a black spike. The head of the hammer can conjure fire.

The Iron Imprisoner III is now free of its gibbet, exposing its grey legs. Both of its feet sport black bands with blue highlights on them. Its collar is much smaller and the grey breastplate it wears is now clearly visible. Its hammer has also filled out.

The Iron Imprisoner IV has shed the last of his shackles. Its black, angry face has been revealed from under its iron mask, and the silver bands on its upper arms have been removed. Its boots and gauntlets have been removed, revealing its natural hands and feet. Most importantly, its hammer has grown even larger, and is more intricately detailed. Its lower legs are light grey and the tips of its feet are red. Its hands are red and black.

The former part of the Iron Imprisoner's name resembles its metallic appearance, while the latter part represents its ability to imprison players in cages. It may also reference the Unversed's own imprisonment in its chains and gibbet.

For the Iron Imprisoner's Final Mix color scheme, its body is now purple with fuchsia arms and legs. The collars on its arms and legs are now green. Its lower body is now locked in a black gibbet with gold highlights, bound in gold chains. The hammer handle is now silver, with a gold spike, and the hammer itself is purple with green highlights. The Iron Imprisoner's helmet is half black and half white.

The Iron Imprisoner is one of the more powerful bosses in the game. The player should have their strongest available Shotlock equipped, but should use the basic form of the available evasive ability, as the offensive versions do not provide invincibility frames to avoid damage. It is also vital that the player equip the Once More and Second Chance abilities, and have several Cure-type Commands in its deck. Vanish, which keeps the Iron Imprisoner from targeting the player, is also a very good idea, but is not necessary. The Damage Syphon ability is also mandatory as the protagonist can absorb the damage taken to charge the Shotlock.

The Iron Imprisoner is stunned by any successful use of Firaga, Triple Firaga, Sonic Blade, Meteor, Double Impact, most projectile Shotlocks, or a finishing attack or combo finisher from certain Command Styles, especially Firestorm.

Note that for all forms, while playing as Aqua, Firaga Burst will damage and remove the cage when it is summoned. While playing as Ventus, Multivortex can deal the most damage for all forms. While playing as Terra, Double Impact is guaranteed to stun all forms, and can be used to stun-lock the Iron Imprisoner until it is defeated.

This is the slowest of the Iron Imprisoner's four forms. In this form, the Iron Imprisoner is chained and trapped in a gibbet. It attacks mainly by swinging the gibbet at you or spinning around like a fiery tornado. It can also entrap you in a cage or erupt out of the ground like a volcano. The best way to start the battle is to use your Shotlock to shave away at its HP bar, then attack normally. It can occasionally shoot lasers from the bottom of its gibbet, dealing fire damage on impact, regardless of how much HP it has.

Overall, it is the easiest of the four forms. Merely dodge the lasers and attack. Alternatively, if you wish to stop any one of its attacks and keep it immobilized, cast Firaga on it repeatedly. While this will inevitably trigger the Firestorm Command Style (or Bladecharge), do not bother too much about attacking with Command Styles unless the player character's Command Style finisher is available for use, as he/she is invincible when performing finishes.

In its second form, the Iron Imprisoner's arms are free, and it holds a massive hammer. It can also spin with the hammer outstretched, dealing fire damage on contact. It retains all of its attacks from its first form, only that it moves slightly faster. Simply dodge, attack and use Shotlocks or cast multiple Firagas on it when possible.

In this form, the Iron Imprisoner's legs are now free of its gibbet. As a result, it is much faster, but it cannot shoot lasers. It retains its other moves so the strategy is the same. Shotlock commands are the most effective way to damage the Iron Imprisoner, and as a result the Damage Syphon ability is very useful. While it will pause periodically, the window of attack is very small, and it is safer to use the time to heal, use a Shotlock or cast multiple Firagas. As it HP dwindles, its movement speed increases and it will unleash its true strength and ferocity on the protagonist which will be a regular move for its true, fourth and final form.
