Abstract
Helping neurons to compensate for proteotoxic stress and maintain function over time (neuronal compensation) has therapeutic potential in aging and neurodegenerative disease. The stress response factor FOXO3 is neuroprotective in models of Huntington’s disease (HD), Parkinson’s disease and motor-neuron diseases. Neuroprotective compounds acting in a FOXO-dependent manner could thus constitute bona fide drugs for promoting neuronal compensation. However, whether FOXO-dependent neuroprotection is a common feature of several compound families remains unknown. Using drug screening in C. elegans nematodes with neuronal expression of human exon-1 huntingtin (128Q), we found that 3ß-Methoxy-Pregnenolone (MAP4343), 17ß-oestradiol (17ßE2) and 12 flavonoids including isoquercitrin promote neuronal function in 128Q nematodes. MAP4343, 17ßE2 and isoquercitrin also promote stress resistance in mutant Htt striatal cells derived from knock-in HD mice. Interestingly, daf-16/FOXO is required for MAP4343, 17ßE2 and isoquercitrin to sustain neuronal function in 128Q nematodes. This similarly applies to the GSK3 inhibitor lithium chloride (LiCl) and, as previously described, to resveratrol and the AMPK activator metformin. Daf-16/FOXO and the targets engaged by these compounds define a sub-network enriched for stress-response and neuronally-active pathways. Collectively, these data highlights the dependence on a daf-16/FOXO-interaction network as a common feature of several compound families for prolonging neuronal function in HD.

Hypoxia-inducible Factor-1 (HIF-1)-independent hypoxia response of the small heat shock protein hsp-16.1 gene regulated by chromatin-remodeling factors in the nematode Caenorhabditis elegans.

Abstract
Oxygen deprivation is accompanied by the coordinated expression of numerous hypoxia-responsive genes, many of which are controlled by hypoxia-inducible factor-1 (HIF-1). However, the cellular response to hypoxia is not likely to be mediated by HIF-1 alone, and little is known about HIF-1-independent hypoxia responses. To better establish the molecular mechanisms of HIF-1-independent hypoxia responses, we sought to characterize the molecular basis of the hypoxia response of the hsp-16.1 gene in the nematode Caenorhabditis elegans; this gene has been shown to be induced by hypoxia independently of hif-1. Using affinity purification followed by LC-MS/MS, we identified HMG-1.2 as a protein that binds to a specific promoter region under hypoxic conditions. By systematic prediction followed by validation of these interactions through RNAi, we identified the chromatin modifiers isw-1 and hda-1, histone H4, and NURF-1 chromatin-remodeling factors as new components of the hif-1-independent hypoxia response. These data suggest that the modulation of nucleosome positioning at the hsp-16.1 promoter may be important for the hypoxia response. In addition, we found that calcineurin acts independently of hif-1 to modulate the cellular response to hypoxia and that calcium ions are necessary for the induction of hsp-16.1 under hypoxic conditions.
