The discovery of regulated cell death (RCD) revolutionized chemotherapy. With caspase-dependent apoptosis initially being thought to be the only form of RCD, many drug development strategies aimed to synthesize compounds that turn on this kind of cell death. While yielding a variety of drugs, this approach is limited, given the acquired resistance of cancers to these drugs and the lack of specificity of the drugs for targeting cancer cells alone. The discovery of non-apoptotic forms of RCD is leading to new avenues for drug design. Evidence shows that ferroptosis, a relatively recently discovered iron-based cell death pathway, has therapeutic potential for anticancer application. Recent studies point to the interrelationship between iron and other essential metals, copper and zinc, and the disturbance of their respective homeostasis as critical to the onset of ferroptosis. Other studies reveal that several coordination complexes of non-iron metals have the capacity to induce ferroptosis. This collective knowledge will be assessed to determine how chelation approaches and coordination chemistry can be engineered to program ferroptosis in chemotherapy.

Dynamic death decisions: How mitochondrial dynamics shape cellular commitment to apoptosis and ferroptosis
The incorporation of mitochondria into early eukaryotes established organelle-based biochemistry and enabled metazoan development. Diverse mitochondrial biochemistry is essential for life and its homeostatic control via mitochondrial dynamics supports organelle quality and function. Mitochondria crosstalk with numerous regulated cell death (RCD) pathways to control the decision to die. In this review, we will focus on apoptosis and ferroptosis, two distinct forms of RCD, that utilize divergent signaling to kill a targeted cell. We will highlight how proteins and processes involved in mitochondrial dynamics maintain biochemically diverse subcellular compartments to support apoptosis and ferroptosis machinery; as well as unite disparate RCD pathways through dual control of organelle biochemistry and the decision to die.

The classic roles of mitochondria in energy production, metabolism, and apoptosis have been well defined. However, a growing body of evidence suggests that mitochondria are also active players in regulating stem cell fate decision and lineage commitment via signaling transduction, protein modification, and epigenetic modulations. This is particularly interesting for spermatogenesis, during which germ cells demonstrate changing metabolic requirements across various stages of development. It is increasingly recognized that proper male fertility depends on exquisitely controlled plasticity of mitochondrial features, activities, and functional states. The unique role of mitochondria in germ cell ncRNA processing further adds another layer of complexity to mitochondrial regulation during spermatogenesis. In this review, we will discuss potential regulatory mechanisms of how mitochondria swiftly reshape their features, activities, and functions to support critical germ cell fate transitions during spermatogenesis. In addition, we will also review recent findings of how mitochondrial regulators coordinate with germline proteins to participate in germ cell-specific activities.more » « less

The use of nanoparticle-based materials to improve the efficacy of photodynamic therapy (PDT) to treat cancer has been a burgeoning field of research in recent years. Polysilsesquioxane (PSilQ) nanoparticles with remarkable features, such as high loading of photosensitizers, biodegradability, surface tunability, and biocompatibility, have been used for the treatment of cancer in vitro and in vivo using PDT. The PSilQ platform typically shows an enhanced PDT performance following a cell death mechanism similar to the parent photosensitizer. Ferroptosis is a new cell death mechanism recently associated with PDT that has not been investigated using PSilQ nanoparticles. Herein, we synthesized a protoporphyrin IX (PpIX)-based PSilQ platform (PpIX-PSilQ NPs) to study the cell death pathways, with special focus on ferroptosis, during PDT in vitro. Our data obtained from different assays that analyzed Annexin V binding, glutathione peroxidase activity, and lipid peroxidation demonstrate that the cell death in PDT using PpIX-PSilQ NPs is regulated by apoptosis and ferroptosis. These results can provide alternative approaches in designing PDT strategies to enhance therapeutic response in conditions stymied by apoptosis resistance.more » « less

Abstract The physical characteristics of brown adipose tissue (BAT) are defined by the presence of multilocular lipid droplets (LDs) within the brown adipocytes and a high abundance of iron‐containing mitochondria, which give it its characteristic color. Normal mitochondrial function is, in part, regulated by organelle‐to‐organelle contacts. For example, the contact sites that mediate mitochondria–LD interactions are thought to have various physiological roles, such as the synthesis and metabolism of lipids. Aging is associated with mitochondrial dysfunction, and previous studies show that there are changes in mitochondrial structure and the proteins that modulate organelle contact sites. However, how mitochondria–LD interactions change with aging has yet to be fully clarified. Therefore, we sought to define age‐related changes in LD morphology and mitochondria–lipid interactions in BAT. We examined the three‐dimensional morphology of mitochondria and LDs in young (3‐month) and aged (2‐year) murine BAT using serial block face‐scanning electron microscopy and the Amira program for segmentation, analysis, and quantification. Our analyses showed reductions in LD volume, area, and perimeter in aged samples in comparison to young samples. Additionally, we observed changes in LD appearance and type in aged samples compared to young samples. Notably, we found differences in mitochondrial interactions with LDs, which could implicate that these contacts may be important for energetics in aging. Upon further investigation, we also found changes in mitochondrial and cristae structure for the mitochondria interacting with LDs. Overall, these data define the nature of LD morphology and organelle–organelle contacts during aging and provide insight into LD contact site changes that interconnect biogerontology with mitochondrial function, metabolism, and bioactivity in aged BAT.more » « less

Abstract In addition to critical roles in bioenergetics, mitochondria are key contributors to the regulation of many other functions in cells, ranging from steroidogenesis to apoptosis. Numerous studies further demonstrate that cell type‐specific differences exist in mitochondria, with cells of a given lineage tailoring their endogenous mitochondrial population to suit specific functional needs. These findings, coupled with studies of the therapeutic potential of mitochondrial transplantation, provide a strong impetus to better understand how mitochondria can influence cell function or fate. Here an inducible mitochondrial depletion modelis used to study how cells lacking endogenous mitochondria respond, on a global protein expression level, to transplantation with lineage‐mismatched (LM) mitochondria. It is shown that LM mitochondrial transplantation does not alter the proteomic profile in nonmitochondria–depleted recipient cells; however, enforced depletion of endogenous mitochondria results in dramatic changes in the proteomic landscape, which returns to the predepletion state following internalization of LM mitochondria. These data, derived from a cell system that can be rendered free of influence by endogenous mitochondria, indicate that transplantation of mitochondria—even from a source that differs significantly from the recipient cell population, effectively restores a normal proteomic landscape to cells lacking their own mitochondria.more » « less
