Although it is unknown whether anemia itself causes the extensive morbidity or mortality seen in older anemic adults, it is plausible to Z-VAD-FMK chemical structure suggest that anemia, potentially leading to local

tissue hypoxia, could aggravate functional decline and, furthermore, that treatment of anemia has the potential to ameliorate some, if not all, of these significant negative effects. This trial involved performing a comprehensive battery of physical, cognitive, quality of life, and frailty tests. Although the findings were modest, this study shows that it is feasible to perform comprehensive evaluations in this population. Such investigation could form the basis for future studies in older anemic adults to better ascertain the exact benefits across relevant domains of physical function, cognition, quality of life, and frailty. Future trials focusing on treatment of UAE should utilize streamlined, patient-friendly design, minimal entry criteria, and intensive recruitment efforts tailored toward older ATM/ATR cancer adults. It will also be critical for future studies of UAE to significantly expand the patient recruitment base by increasing the numbers of participating institutions.

“Hepcidin is a cysteine-rich peptide hormone that regulates the absorption and distribution of iron in humans and other animals [1]. Hepcidin production is transcriptionally regulated in the liver in response to body iron stores and inflammation [2]. Increases in plasma iron levels result in enhanced signaling via bone morphogenic proteins [3] and phosphorylation of Smad1,5, and 8, which facilitates Smad4 binding to the Hepcidin promoter and greater Hepcidin transcription [4]. The inflammatory cytokine, interleukin-6, IL-6, can also upregulate Hepcidin by activating Stat3 and enhancing Stat3 binding to the Hepcidin promoter [5]. Hepcidin binds ferroportin1, the only known vertebrate iron exporter, resulting in internalization and degradation of both proteins [6].
