MYC gene alterations have been identiﬁed in other mature B-cell neoplasms that are usually associated with an aggressive clinical behavior. Most of these tumors originate in cells that do not normally express MYC protein. The oncogenic events leading to MYC up-regulation seem to overcome the inhibitory effect of physiological repressors such as BCL6 or BLIMP1. Aggressive lymphomas frequently carry additional oncogenic alterations that cooperate with MYC dysregulation, likely counteracting its proapoptotic function. The development of FISH probes and new reliable antibodies have facilitated the study of MYC gene alterations and protein expression in large series of patients, providing new clinical and biological perspectives regarding MYC dysregulation in aggressive lymphomas. MYC gene alterations in large B-cell lymphomas are frequently associated with BCL2 or BCL6 translocations conferring a very aggressive behavior. Conversely, MYC protein up-regulation may occur in tumors without apparent gene alterations, and its association with BCL2 overexpression also confers a poor prognosis.

Heeney1 1Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, Boston, MA Iron is an ubiquitous metal of vital importance to the normal physiologic processes of many organisms. Over the last 2 decades, the discovery of mutations in genes leading to hereditary disorders of iron overload, iron deﬁciency, and iron maldistribution have accelerated our understanding of human iron homeostasis. This chapter provides an updated overview of the human iron cycle, regulation of iron homeostasis, and how perturbations in these homeostatic mechanisms lead to iron overload disease and provides strategies for the diagnosis of hereditary iron overload. This excess cellular iron deposition ultimately exceeds the capacity of iron-binding proteins, thereby leading to cellular damage, organ dysfunction, and eventually to clinical symptoms. Introduction Iron is an essential metal for many biological processes due to its Ferritin is the primary intracellular iron storage protein, which ability to transfer electrons in reduction/oxidation reactions. This forms multimeric complexes that facilitate iron sequestration and reactivity also provides the potential for great damage to biological mobilization depending on cellular need. In contrast, hemosiderin is systems if iron is not chaperoned through a tightly regulated an amorphous and poorly bioavailable iron-containing conglomer- network of iron-binding proteins and transporters. If the capacity of ate the presence of which is generally a pathologic sign of cellular these iron-binding proteins is exceeded, “free” iron is capable of iron excess. A soluble form of ferritin is also found in the plasma forming reactive oxygen species that may damage macromolecular and is expelled primarily from reticuloendothelial macrophages and cellular components such as nucleic acids, proteins, and lipids and the liver; however, its biological role remains unclear. Iron homeostasis in humans is maintained ferritin correlates with iron stores in many conditions; however, almost exclusively at the level of intestinal absorption because caution must be taken before interpreting in the setting of inﬂamma- evolution has not provided a physiologically regulated mechanism tion and cellular injury. The large size and electrochemical properties of iron require that it Iron homeostasis be transported across the mammalian cell membranes by speciﬁc transmembrane proteins that mediate cellular iron uptake (import) Iron recycling and storage and iron release (export). Although hepatocytes, intestinal mucosal The primary role of iron in mammals is to provide a binding site for cells, and macrophages possess speciﬁc carriers for iron import and oxygen in the heme moiety of hemoglobin. The average adult male export, erythroid cells only import iron and do not “release” iron has a total body iron content of 4g, 2/3 of which is contained in until they are lysed or phagocytosed within the reticuloendothelial the erythroid compartment. When iron stores are depleted through decreased dietary intake cyte cytoplasm as ferritin and the remainder is exported through the or intestinal absorption, increased requirements (eg, pregnancy) or enterocyte basolateral membrane into the plasma via the transmem- loss (eg, intestinal blood loss), erythropoiesis becomes iron re- brane iron exporter ferroportin (FPN; described more fully in the stricted and eventually results in the characteristic microcytic, Cellular iron export section). In contrast, erythropoiesis in most iron overload states is relatively unperturbed; however, Nonheme iron is imported into nonintestinal cell types from the HFE hemochromatosis is associated with increases in hemoglobin, plasma by the transferrin (TF) cycle (for review, see Chen and 202 American Society of Hematology Paw6). Almost all plasma iron exists bound to the abundant hepcidin leads to enhanced intestinal absorption and macrophage glycoprotein TF. Each TF molecule binds 2 Fe3 iron atoms with iron release, elevated plasma iron levels, and iron loading. The TF cycle begins with Hepcidin exerts its central role in iron homeostasis through its iron-loaded plasma TF binding with high afﬁnity to TF receptor 1 effect on FPN, the only known receptor for hepcidin and cellular (TFR1) on the cell surface and being endocytosed. Hepcidin binds to FPN at the cell surface, resulting then acidiﬁed, prompting the release of iron from TF and the empty in endocytosis and lysosomal degradation,19 blocking of iron TF and TFR1 return to the cell surface and are available to repeat the efﬂux into the plasma, hypoferremia, and iron-restricted cycle again. The unbound Fe3 iron in the acidiﬁed endosome is erythropoiesis. Clinically, plasma hepcidin concentration is modulated by several “regulators. It is unclear whether intestinal heme absorption uses The physiologic regulation of hepcidin expression is controlled at membrane-bound transporters or endocytic uptake. Although a responsive gene-1, (HRG-1), initially identiﬁed by homology to great deal remains to be elucidated regarding the molecular control heme transporters found in Caenorhabditis elegans.
