Description
The NF-B pathway is a master regulator of inflammatory processes and is implicated in insulin resistance and pancreatic beta cell dysfunction in the metabolic syndrome. While canonical NF-B signaling is well studied, there is little information on the divergent non-canonical NF-B pathway in the context of pancreatic islet dysfunction in diabetes. Here, we demonstrate that pharmacological activation of the non-canonical NF-B inducing kinase (NIK) disrupts glucose homeostasis in zebrafish in vivo. Further, we identify NIK as a critical negative regulator of beta cell function as pharmacological NIK activation results in impaired glucose-stimulated insulin secretion in mouse and human islets. NIK levels are elevated in pancreatic islets isolated from diet-induced obese (DIO) mice, which exhibit increased processing of non-canonical NF-B components p100 to p52, and accumulation of RelB. Tumor necrosis factor (TNF) and receptor activator of NF-B ligand (RANKL), two ligands associated with diabetes, induce NIK in islets. Mice with constitutive beta cell intrinsic NIK activation present impaired insulin secretion with DIO. NIK activation triggers the non-canonical NF-B transcriptional network to induce genes identified in human type 2 diabetes genome-wide association studies linked to beta cell failure. These studies reveal that NIK contributes a central mechanism for beta cell failure in diet-induced obesity.

Description
Huntington’s disease (HD) is an autosomal dominant neurodegenerative disease whose predominant neuropathological signature is the selective loss of medium spiny neurons in the striatum. Despite this selective neuropathology, the mutant protein (huntingtin) is found in virtually every cell so far studied, and, consequently, phenotypes are observed in a wide range of organ systems both inside and outside the central nervous system. We, and others, have suggested that peripheral dysfunction could contribute to the rate of progression of striatal phenotypes of HD. To test this hypothesis, we lowered levels of huntingtin by treating mice with antisense oligonucleotides (ASOs) targeting the murine Huntingtin gene. To study the relationship between peripheral huntingtin levels and striatal HD phenotypes, we utilized a knock-in model of the human HD mutation (the B6.HttQ111/+ mouse). We treated mice with ASOs from 2-10 months of age, a time period over which significant HD-relevant signs progressively develop in the brains of HttQ111/+ mice. Peripheral treatment with ASOs led to persistent reduction of huntingtin protein in peripheral organs, including liver (64% knockdown), brown adipose (66% knockdown), and white adipose tissues (71% knockdown). This reduction was not associated with alterations in the severity of HD-relevant signs in the striatum of HttQ111/+ mice at the end of the study, including transcriptional dysregulation, the accumulation of neuronal intranuclear inclusions, and behavioral changes such as subtle hypoactivity and reduced exploratory drive. These results suggest that the amount of peripheral reduction achieved in the current study does not significantly impact the progression of HD-relevant signs in the central nervous system. Overall design: HttQ111/+ and Htt+/+ mice were given weekly intraperitoneal injections of Htt ASO, control ASO, or saline from 2 to 10 months of age. Striatal mRNA was sequenced from and N of 5-6 per arm (N=35 total).

Description
Excessive consumption of beverages sweetened with high-fructose corn syrup (HFCS) is associated with obesity and with an increased risk of colorectal cancer. Whether HFCS contributes directly to tumorigenesis is unclear. We investigated the effects of daily oral administration of HFCS in APC mutant mice, which are predisposed to develop intestinal tumors. The HFCS-treated mice showed a dramatic increase in tumor size and tumor grade in the absence of obesity or metabolic syndrome. HFCS increased the levels of fructose and glucose in the intestinal lumen and serum, respectively, and the tumors absorbed both sugars. Within the tumors, fructose was converted to fructose-1-phosphate, leading to activation of glycolysis and increased synthesis of fatty acids that support tumor growth. These mouse studies support the hypothesis that the combination of dietary glucose and fructose, even at a moderate dose, can enhance tumorigenesis. Overall design: We investigated tumor and small intestines in APC mutant mice, which are predisposed to develop intestinal tumors.

Description
Huntington''s disease (HD) is an autosomal dominant neurodegenerative disorder that is characterized by motor, cognitive, and psychiatric alterations. The mutation responsible for this disease is an abnormally expanded and unstable CAG repeat within the coding region of the gene encoding huntingtin (Htt). Knock-in mouse models of HD with human exon 1 containing expanded CAG repeats inserted in the murine huntingtin gene (Hdh) provide a genetic reconstruction of the human causative mutation within the mouse model. The goal of this study is RNA expression profiling by RNA sequencing (RNA-seq) in 2, 6, and 10 month old knock-in mice with CAG lengths of 20, 80, 92, 111, 140, 175 along with littermate control wild-type animals Overall design: mRNA expression profiles were obtained via RNA-seq analysis performed on tissue samples from the cortex of 2, 6, and 10 month old knock-in mice with CAG lengths of 20, 80, 92, 111, 140, 175 along with littermate control wild-type animals.
