Abstract
SIGNIFICANCE Detailed knowledge about cell death and cell survival mechanisms and how these pathways are impaired in neurodegenerative disorders and cancer forms the basis for future drug development for these diseases that affect millions of people around the world. RECENT ADVANCES In neurodegenerative disorders such as Alzheimer's disease (AD), cell death pathways are inappropriately activated, resulting in neuronal cell death. In contrast, cancer cells develop resistance to apoptosis by regulating anti-apoptotic proteins signaling via mitochondria. Mounting evidence shows that mitochondrial function is central in both cancer and AD. Cancer cells typically shut down oxidative phosphorylation (OXPHOS) in mitochondria and switch to glycolysis for ATP production, making them resistant to hypoxia. In AD, for example, amyloid-β peptide (Aβ) and reactive oxygen species impair mitochondrial function. Neurons therefore also switch to glycolysis to maintain ATP production and to produce molecules involved in antioxidant metabolism in an attempt to survive. CRITICAL ISSUES One critical difference between cancer cells and neurons is that cancer cells can survive without OXPHOS, while neurons are dependent on OXPHOS for long-term survival. FUTURE DIRECTIONS This review will focus on these abnormalities of mitochondrial function shared in AD and cancer and discuss the potential mechanisms underlying links that may be key steps in the development of therapeutic strategies.

Abstract
Systemic delivery of fenretinide in oral cancer chemoprevention trials has been largely unsuccessful due to dose-limiting toxicities and subtherapeutic intraoral drug levels. Local drug delivery, however, provides site-specific therapeutically relevant levels while minimizing systemic exposure. These studies evaluated the pharmacokinetic and growth-modulatory parameters of fenretinide mucoadhesive patch application on rabbit buccal mucosa. Fenretinide and blank-control patches were placed on right/left buccal mucosa, respectively, in eight rabbits (30 min, q.d., 10 days). No clinical or histological deleterious effects occurred. LC-MS/MS analyses of post-treatment samples revealed a delivery gradient with highest fenretinide levels achieved at the patch-mucosal interface (no metabolites), pharmacologically active levels in fenretinide-treated oral mucosa (mean: 5.65 μM; trace amounts of 4-oxo-4-HPR) and undetectable sera levels. Epithelial markers for cell proliferation (Ki-67), terminal differentiation (transglutaminase 1-TGase1) and glucuronidation (UDP-glucuronosyltransferase1A1-UGT1A1) exhibited fenretinide concentration-specific relationships (elevated TGase1 and UGT1A1 levels <5 μM, reduced Ki-67 indices >5 μM) relative to blank-treated epithelium. All fenretinide-treated tissues showed significantly increased intraepithelial apoptosis (TUNEL) positivity, implying activation of intersecting apoptotic and differentiation pathways. Human oral mucosal correlative studies showed substantial interdonor variations in levels of the enzyme (cytochrome P450 3A4-CYP3A4) responsible for conversion of fenretinide to its highly active metabolite, 4-oxo-4-HPR. Complementary in vitro assays in human oral keratinocytes revealed fenretinide and 4-oxo-4-HPR's preferential suppression of DNA synthesis in dysplastic as opposed to normal oral keratinocytes. Collectively, these data showed that mucoadhesive patch-mediated fenretinide delivery is a viable strategy to reintroduce a compound known to induce keratinocyte differentiation to human oral cancer chemoprevention trials.

Abstract
Protein complexes are a cornerstone of many biological processes and together they form various types of molecular machinery. A broad understanding of these protein complexes is crucial for revealing and building models of protein function and regulation. Pancreatic cancer is a highly lethal disease which is difficult to diagnose at early stage and even more difficult to cure. In this study, we applied a gradient clear native gel system combined with subsequent second-dimensional SDS-PAGE to separate protein complexes from cell lysates of SW1990 and PANC-1 pancreatic cancer cell lines with different degrees of differentiation. Ten heat-shock-protein- (HSP-) associated protein complexes were separated and identified, and the differentially expressed proteins related to cancers were also found, such as HSP60, protein disulfide-isomerase A4 (ERp72), and transitional endoplasmic reticulum ATPase (TER ATPase).

Abstract
Wilms tumor is the most common malignant tumor in the pediatric kidney. Anaplasia, focal or diffuse as defined by histological criteria, is the most important parameter to guide the clinical treatment plan. We sought to identify and characterize potential useful biomarkers associated with anaplasia and provide insight into the peculiar molecular biology of Wilms tumor with unfavorable histology. Utilizing isobaric tagging technology for relative and absolute quantitation, coupled with tandem mass spectrometry, we identified proteins that are differently regulated in different Wilms tumor histologies. Four Wilms tumor specimens were selected, including two with classic favorable histology, one with focal anaplasia, and one with diffuse anaplasia. A total of 256 proteins with a Protein Score >1.0 are identified from all samples (proteins with >90% confidence). Compared with classic favorable morphology: in the focal anaplasia group, we identified a total of 26 proteins of which six were underexpressed and 20 were overexpressed; in the diffuse anaplasia group, we identified a total of 20 proteins of which eight were underexpressed and 12 were overexpressed. With a total of 39 involved proteins, seven were common to both the focal and diffuse anaplasia cases, and clearly seemed to have a similar regulation. The newly identified potential markers for Wilms tumor with unfavorable histology include ENO1, GAPDH, ALDOA, SLC25A6, LDHA, PGAM1, MIF, RBP1, HBA, HP, COL1A1, CFL1, and FSCN1 etc. In Wilms tumors, though there are unfavorable histology differences (focal or diffuse anaplasia), the protein expression seems to be similarly dysregulated compared with the favorable histology group. The newly identified potential markers may provide insights into the molecular biology of Wilms tumor and may have practical implications.

Abstract
This review focuses on post sampling changes and how the Stabilizor system has been used to control this natural biological process and potential implications on cancer-specific biomarkers due to post sampling changes. Tissue sampling is a major traumatic event that can have drastic effects within a very short timeframe at the molecular level [1] resulting in loss of sample quality due to post-mortem changes. A heat-stabilization technology, using the Stabilizor system, has been developed to quickly and permanently abolish the enzymatic activity that causes these changes post-sampling and so preserve sample quality. The Stabilizor system has been shown to give better sample quality when analyzing a variety of tissues in various proteomic workflows. In this paper we discuss the impact of using heat-stabilized tissue in different proteomic applications. Based on our observations regarding the overlap between commonly changing proteins and proteins found to change post-mortem we also highlight a group of proteins of particular interest in cancer studies.
